Should it appear that the work to be done or any of the relative matters are not sufficiently detailed or explained in the Contract Documents, the Contractor shall apply to the Engineer for such further explanations as may be necessary and shall conform to them as part of the Contract. In the event of any doubt or question arising respecting the true meaning of the Contract Documents, reference shall be made to the Engineer, whose written decision thereon shall be final and conclusive.

Neither the payment of any estimate nor of any retained percentage shall relieve the Contractor of any obligation to make good any defective work or material. B. No compensation will be made in any case for loss of anticipated profits. Increased or decreased work involving supplemental agreements will be paid for as provided in such agreements. 2.07 PAYMENT OF TAXES A. The Contract prices paid for the work shall include full compensation for all taxes which the Contractor is required to pay, whether imposed by Federal, State, or local governments. 2.08 PATENTS A.

The District may, at any time, by written order make changes in the work as deemed necessary by the Engineer. If such changes cause an increase or decrease in the Contractor's cost of, or time required for, performance of the Contract an equitable adjustment will be made to the Contract and the Contract modified in writing accordingly. Such modifications are subject to approval by the Board, in accordance with Public Contract Code §20206.2 and 20206.3. B. Such modification will be in the form of a Contract Change Order which will describe the work to be done or the method by which the change and cost and/or time adjustment, if any, will be determined, and the time of completion of the work. C. The compensation to be paid for any extra work or change shall be determined in one or more of the following ways: 1. By agreed unit prices; 2. By estimate and acceptance of an agreed upon lump sum; or 3. By cost plus. MARCH 2026 SECTION 00 72 00 2026 WATER METER INSTALLATION PROJECT GENERAL CONDITIONS 4 The unit prices established in the Bid for a particular item shall be valid for deviations in the bid quantity within the range established in the Bid Form (Section 00 41 00). D. Until one of the above methods is agreed on, or if the work is to be paid for on cost plus basis, the Contractor shall keep full and complete records of the cost of such work in the form and manner prescribed by the Engineer and shall permit the Engineer to have access to such records as may be necessary to assist in the determination of the compensation payable for such work. Contractor must obtain the Engineer's permission, on a daily basis, as to the size of the crew, hours worked, and material to be used. E. Upon receipt of a Contract Change Order, the Contractor shall proceed with the ordered work. If ordered in writing by the Engineer, the Contractor shall proceed with the work so ordered prior to actual receipt of a Contract Change Order. A Contract Change Order executed by the Contractor and approved by the Engineer is an executed Contract Change Order as that term is used throughout this Section. F. A Contract Change Order may be issued to the Contractor at any time. Should the Contractor disagree with any terms or conditions set forth in a Contract Change Order which has not been executed, the Contractor shall submit a written protest to the Engineer within ten (10) days after the receipt of such Contract Change Order. The protest shall state the points of disagreement, and, if possible, the quantities and cost involved. If a written protest is not submitted, payment will be made as provided in the Contract Change Order and such payment will constitute full compensation for all work included therein or required thereby. Such unprotested Contract Change Orders will be considered as executed Contract Change Orders. Contractor's disagreement with any Change Order does not relieve the Contractor from performance of the work, including extra work, promptly and expeditiously. G. Where the protest concerning a Contract Change Order relates to compensation, the compensation payable for all work specified or required by said Contract Change Order to which such protest relates will be determined in the same manner as provided in Part 2.10 for claims for extra work. The contractor shall keep full and complete records of the cost of such work and shall permit the Engineer to have such access thereto as may be necessary to assist in the determination of the compensation payable for such work. H. Where the protest concerning a Contract Change Order relates to the adjustment of time and the completion of the work, the time to be allowed therefore will be determined as provided in this Section. I.

MARCH 2026 SECTION 00 72 00 2026 WATER METER INSTALLATION PROJECT GENERAL CONDITIONS 5 2.10 EXTRA WORK A. If, during the performance of the Contract, it shall, in the opinion of the District or the Engineer, become necessary or desirable for the proper completion of the Contract to order work done or materials or equipment furnished which in the opinion of the Engineer are not susceptible of classification under the unit-price items in the Bidding Schedule and are not included in any item for which a lump sum is bid, the Contractor shall do and perform such work and furnish such materials and equipment. Such labor, materials and/or equipment will be classed as extra work, and shall be ordered in writing before such work is started. No extra work will be paid for unless ordered in writing. Extra work and materials will ordinarily be paid for at a lump sum or unit-price agreed on in writing by the Engineer and Contractor prior to the time when the Engineer ordered the extra work to be done. The performance of any extra work or the furnishing of extra material which, in the judgment of the Engineer, is of like character to and susceptible of classification under the unit-price items of the Contract as specified shall, if the order of the Engineer shall so provide, be paid for at the unit-price named for such work in the Bidding Schedule. Whenever, in the judgment of the Engineer, such extra work or such extra material as the case may be, is not of like character to and susceptible of classification under the unit-price items of the Contract as specified, and it is impracticable because of the nature of the work, or for any other reason, to fix the price before order for the extra work shall be issued, the Contractor shall be entitled to be paid the sum of the following costs for doing the extra work, which shall be known as the cost plus basis of payment: 1. Direct Labor Cost - Charges for all of the labor furnished and used by the Contractor shall be as identified in the California Prevailing Wage Determination. Under no circumstances shall the Contractor be allowed to pay for labor, any amount that is less than the California prevailing Wage Determination. The Contractor shall be allowed to add to actual wages paid the labor surcharge set forth in the California Department of Transportation publication entitled Labor Surcharge and Equipment Rental Rates, which is in effect on the date upon which the work is performed. The surcharge shall constitute full compensation for all payments imposed by State and Federal laws and for all other payments made to, or on behalf of, the workers, other than actual wages as defined in Section 9-1.04B1 of the California Department of Transportation Standard Specifications. 2. Equipment Cost - Charges for the rental and operation of the equipment furnished and used by the Contractor shall be made for all prime construction and automotive equipment. It shall not include charges for listed equipment or major tools with a new cost of$500.00 or less. Equipment time charges shall be subject to the daily approval of the Engineer and evidence of such daily approval submitted with the billing. The equipment rental and operation rates used shall be at the established CalTrans rental rates. No time or charges will be allowed except when equipment is actually being used for the proper and efficient performance or completion of the extra work as authorized. A MARCH 2026 SECTION 00 72 00 2026 WATER METER INSTALLATION PROJECT GENERAL CONDITIONS 6 fifteen percent (15%) markup to the equipment rental and operation rates will be allowed. 3. Material Costs - Charges for the cost of materials furnished by the Contractor shall be made provided such furnishing was specifically authorized in the extra work order and the actual use verified by the Engineer. Charges shall be net cost to the Contractor delivered at the job, including all applicable sales taxes and vendor's invoice must accompany the billing along with verification of use of such materials by the Engineer. A fifteen percent (15%) markup to the materials cost will be allowed. 4. Tools, Supplies, Supervision, Overhead and Profit - A charge for major tools, supplies, home office overhead, field overhead, labor liability insurance, additional bond costs, other fixed or administrative costs that are not costs of labor used in the direct performance of the work, supervision, and profit will be allowed in the amount of thirty five percent (35%) of the total direct labor costs as defined above. 5. Work by Subcontractor- When all or any part of extra work is performed by any of the Contractor's Subcontractors, the markups for tools, supplies, additional bond costs, supervision, overhead and profit applied to the Subcontractor's actual cost of such work (determined as above) will be allowed in the amount of ten percent (10%) of the total direct labor costs, equipment costs and material costs, as defined above, to which a markup of five percent (5%) on the subcontracted portion of the extra work may be added by the Contractor. B. The Contractor agrees that he shall not be entitled to claim damages for anticipated profits on any portion of work that may be deleted. The amount of any adjustment for work deleted shall be estimated at the time deletion of work is ordered and the estimated adjustment will be deducted from the Contract amount by Contract Change Order. C. The District reserves the right to contract with any person or firm other than the Contractor for any or all extra work. 2.11 CLAIMS FOR EXTRA COSTS A. The Contractor shall not be entitled to the payment of any additional compensation for any cause, including any act, or failure to act, by the Engineer, or the happening of any event, thing, or occurrence, unless he shall have given the Engineer written notice of claims specified in Part 2.20 below, provided, however, that compliance with this section shall not be a prerequisite as to matters within the scope of the protest provisions in Part 2.09. B. Contractor shall not reserve a right to assert impact costs, extended job site costs, extended overhead, constructive acceleration and/or actual acceleration beyond what is stated in the change order for work. No claims shall be allowed of impact, extended overhead costs, constructive acceleration and/or actual acceleration due to a multiplicity of changes and/or clarifications. The Contractor may not change or modify the District's change order form in an attempt to reserve additional rights. MARCH 2026 SECTION 00 72 00 2026 WATER METER INSTALLATION PROJECT GENERAL CONDITIONS 7 C. The District's liability to Contractor for delays for which the District is responsible shall be limited to only an extension of time unless such delays were unreasonable under the circumstances. In no case shall the District be liable for any costs which are borne by the Contractor in the regular course of business, including, but not limited to, home office overhead and other ongoing costs. Damages caused by unreasonable District delay, including delays caused by items that are the responsibility of the District pursuant to Government Code section 4215, shall be based on actual costs only, no proportions or formulas shall be used to calculate any delay damages. In the event of an emergency endangering life or property, the Contractor shall act as stated in Section 01 35 00, Special Procedures, Part 2.01, and after execution of the emergency work shall present an accounting of labor, materials, and equipment. The procedure for any payment that may be due for emergency work will be as specified in Part 2.09 above. 2.12 CHANGES IN CHARACTER OF WORK A. If an ordered change in the Contract Documents materially changes the character of the work of a Contract item from that upon which the Contractor based its Bid price, and if the change increases or decreases the actual unit costs of such changed item as compared to the actual or estimated unit cost of performing the work of said item in accordance with the Contract Documents originally applicable thereto, in the absence of an executed Contract Change Order specifying the compensation payable, an adjustment in compensation therefore will be made in accordance with the following: 1. The basis of such adjustment in compensation will be the difference between the Contract unit-price to perform the work of said item or portion thereof involved in the change as originally planned and the actual unit cost of performing the work of said item or portion thereof involved in the change, as changed. Actual unit costs will be as agreed upon by the Contractor and the Engineer. If they cannot agree or if there is no unit price for the subject work, then the costs of the work will be determined by the Engineer in the same manner as if the work were to be paid for on the cost plus basis as provided in Part 2.10. Any such adjustment will apply only to the portion of the work of said item actually changed in character. 2. Failure of the Engineer to recognize the change in character of the work at the time the Contract Change Order is issued shall not be construed as relieving the Contractor of its duties and responsibility of filing a written protest within the ten (10) day limit as hereinabove provided. 2.13 RIGHT TO WITHHOLD PAYMENTS A. In addition to all other rights and remedies of the District hereunder and by virtue of the law, the District may withhold or nullify the whole or any part of any partial or final payment to such extent as may reasonably be necessary to protect the District from loss on account of: 1.

Legally permitted penalties, including governmental and regulatory fines incurred by the District as a result of delays resulting from Contractor's performance of the work as set forth in Section 01 35 00, Part 2.06; and 15. Damages and costs incurred by the District as a result of Contractor's performance of the work, including, but not limited to, legal, engineering, inspection, superintendence, regulatory fines, and other expenses. B. Whenever the District shall, in accordance herewith, withhold any monies otherwise due the Contractor, written notice of the amount withheld and the reasons therefore will be given the Contractor. After the Contractor has corrected the enumerated deficiencies, the District will promptly pay to the Contractor the amount so withheld. When monies are withheld to protect the District against claims or liens of mechanics, materialmen, Subcontractors, etc., the District may at its discretion permit the Contractor to deliver a surety bond in terms and amount satisfactory to the District, indemnifying the District against any loss or expense, and upon acceptance thereof by the District, the District shall release to the Contractor monies so withheld.

In the event of failure to complete such repairs within a reasonable time, the District is authorized to have the defect repaired and corrected at the expense of the Contractor who will pay the costs and charges therefor immediately upon demand, including any reasonable management and administrative costs, engineering, legal and other consultant fees incurred to enforce this section. MARCH 2026 SECTION 00 72 00 2026 WATER METER INSTALLATION PROJECT GENERAL CONDITIONS 10 H. If the Engineer deems it inexpedient for the Contractor to correct work damaged or not done in accordance with the Contract, an equitable deduction from the Contract price shall be made therefore, and such sum may be withheld by District from Contractor's payment. I.

The final five percent (5%), or the percentage specified in the notice inviting bids where the District has adopted a finding of substantially complete, shall not become due and payable until five (5) calendar days shall have elapsed after the expiration of the period within which all claims may be filed under the provisions of Civil Code section 9356. If the Contractor has placed securities with the District as described herein, the Contractor shall be paid a sum equal to one hundred percent (100%) of the contract price less any amounts due the District under the terms of the Contract. B. Unless Contractor advises the District in writing prior to acceptance of the final five percent (5%) or the percentage specified in the notice inviting bids where the District has adopted a finding of substantially complete, or the return of securities held as described herein, said acceptance shall operate as a release to the District of all claims and all liability to Contractor for all things done or furnished in connection with this work and for every act of negligence of the District and for all other claims relating to or arising out of this work. If Contractor advises the District in writing prior to acceptance of final payment or return of the securities that there is a dispute regarding the amount due the Contractor, the District may pay the undisputed amount contingent upon the Contractor furnishing a release of all undisputed claims against the District with the disputed claims in stated amounts being specifically excluded by Contractor from the operation of the release. No payments, however, final or otherwise, shall operate to release Contractor or MARCH 2026 SECTION 00 72 00 2026 WATER METER INSTALLATION PROJECT GENERAL CONDITIONS 11 its sureties from the Faithful Performance Bond, Labor and Material Payment Bond, or from any other obligation under this contract. C. In case of suspension of the contract any unpaid balance shall be and become the sole and absolute property of the District to the extent necessary to repay the District any excess in the cost of the Work above the contract price.

Within ten (10) calendar days from the time that all or any portion of the retention proceeds are received by Contractor, Contractor shall pay each of its subcontractors from whom retention has been withheld each subcontractor's share of the retention received. However, if a retention payment received by Contractor is specifically designated for a particular subcontractor, payment of the retention shall be made to the designated subcontractor if the payment is consistent with the terms of the subcontract. 2.17 OCCUPANCY A. The District reserves the right to occupy or utilize any portion of the Work at any time before completion, and such occupancy or use shall not constitute acceptance of any part of Work covered by this Contract. This use shall not relieve the Contractor of its responsibilities under the Contract. 2.18 INDEMNIFICATION A. To the fullest extent permitted by law, Contractor shall immediately defend (with counsel of the District's choosing), indemnify and hold harmless the District, officials, officers, agents, employees, and representatives, and each of them from and against: 1.

Any and all actions, proceedings, damages, costs, expenses, fines, penalties or liabilities, in law or equity, of every kind or nature whatsoever, arising out of, resulting from, or on account of the violation of any governmental law or regulation, compliance with which is the responsibility of Contractor. 4. Any and all losses, expenses, damages (including damages to the Work itself), attorney's fees, and other costs, including all costs of defense which any of them may incur with respect to the failure, neglect, or refusal of Contractor to faithfully perform the Work and all of Contractor's obligations under the agreement.

The requirements of this section must be included in all subawards including all contracts and purchase orders for work or products under this award. 1. Produced in the United States" means, for iron and steel products, that all manufacturing processes, from the initial melting stage through the application of coatings, occurred in the United States. 2. Manufactured products" means items and construction materials composed in whole or in part of non-ferrous metals such as aluminum; plastics and polymer-based products such as polyvinyl chloride pipe; aggregates such as concrete; glass, including optical fiber; and lumber 2.03 DAVIS-BACON ACT PROVISIONS A. Contractor shall comply with the following provisions of the Davis-Bacon Act. "(1) Minimum wages. (i) All laborers and mechanics employed or working upon the site of the work will be paid unconditionally and not less often than once a week, and without subsequent deduction or rebate on any account (except such payroll deductions as are permitted by regulations issued by the Secretary of Labor under the Copeland Act (29 CFR part 3)), the full amount of wages and bona fide fringe benefits (or cash equivalents thereof) due at time of payment computed at rates not less than those contained in the wage determination of the Secretary of Labor which is attached hereto and made a part hereof, regardless of any contractual relationship which may be alleged to exist between the contractor and such laborers and mechanics. Contributions made or costs reasonably anticipated for bona fide fringe benefits under section 1(b)(2) of the DB Act on behalf of laborers or mechanics are considered wages paid to such laborers or mechanics, subject to the provisions of paragraph (a)(1)(iv) of this section; also, regular contributions made or costs incurred for more than a weekly period (but not less often than quarterly) under plans, funds, or programs which cover the particular weekly period, are deemed to be constructively made or incurred during such weekly period. Such laborers and mechanics shall be paid the appropriate wage rate and fringe benefits on the wage determination for the classification of work actually performed, without regard to skill, except as provided in § 5.5(a)(4). Laborers or mechanics performing work in more than one classification may be compensated at the rate specified for each classification for the time actually worked therein: Provided that the employer's payroll records MARCH 2026 SECTION 00 74 00 2026 WATER METER INSTALLATION PROJECT GRANT CONDITIONS 2 accurately set forth the time spent in each classification in which work is performed. The wage determination (including any additional classification and wage rates conformed under paragraph (a)(1)(ii) of this section) and the DB poster (WH-1321) shall be posted at all times by the contractor and its subcontractors at the site of the work in a prominent and accessible place where it can be easily seen by the workers. Sub recipients may obtain wage determinations from DOL's website, https://sam.gov/. (ii)(A) The sub recipient(s), on behalf of EPA, shall require that any class of laborers or mechanics, including helpers, which is not listed in the wage determination and which is to be employed under the contract shall be classified in conformance with the wage determination. The State award official shall approve a request for an additional classification and wage rate and fringe benefits therefore only when the following criteria have been met: (1) The work to be performed by the classification requested is not performed by a classification in the wage determination; and (2) The classification is utilized in the area by the construction industry; and (3) The proposed wage rate, including any bona fide fringe benefits, bears a reasonable relationship to the wage rates contained in the wage determination. (B) If the contractor and the laborers and mechanics to be employed in the classification (if known), or their representatives, and the sub recipient(s) agree on the classification and wage rate (including the amount designated for fringe benefits where appropriate), documentation of the action taken and the request, including the local wage determination shall be sent by the sub recipient (s) to the State award official. The State award official will transmit a completed conformance request form (SF-1444 or similar) and supporting materials to WHDCBACONFORMANCE_INCOMING@dol.gov and to the EPA DB Regional Coordinator concurrently. The DOL Administrator, or an authorized representative, will approve, modify, or disapprove every additional classification request within 30 days of receipt and so advise the State award official or will notify the State award official within the 30- day period that additional time is necessary. (C) In the event the contractor, the laborers or mechanics to be employed in the classification or their representatives, and the sub recipient(s) do not agree on the proposed classification and wage rate (including the amount designated for fringe benefits, where appropriate), documentation of the action taken and the request, including the local wage determination shall be sent by the sub recipient (s) to the State award official. The State award official will transmit a completed conformance request form (SF-1444 or similar) which indicates the State award official's disagreement and supporting materials to WHD- CBACONFORMANCE_INCOMING@dol.gov MARCH 2026 SECTION 00 74 00 2026 WATER METER INSTALLATION PROJECT GRANT CONDITIONS 3 and to the EPA DB Regional Coordinator concurrently. The DOL Administrator, or an authorized representative, will issue a determination within 30 days of receipt of the request and so advise the contracting officer or will notify the contracting officer within the 30-day period that additional time is necessary. (D) The wage rate (including fringe benefits where appropriate) determined pursuant to paragraphs (a)(1)(ii)(B) or (C) of this section, shall be paid to all workers performing work in the classification under this contract from the first day on which work is performed in the classification. (iii) Whenever the minimum wage rate prescribed in the contract for a class of laborers or mechanics includes a fringe benefit which is not expressed as an hourly rate, the contractor shall either pay the benefit as stated in the wage determination or shall pay another bona fide fringe benefit or an hourly cash equivalent thereof. (iv) If the contractor does not make payments to a trustee or other third person, the contractor may consider as part of the wages of any laborer or mechanic the amount of any costs reasonably anticipated in providing bona fide fringe benefits under a plan or program, Provided, That the Secretary of Labor has found, upon the written request of the contractor, that the applicable standards of the DB Act have been met. The Secretary of Labor may require the contractor to set aside assets in a separate account for the meeting of obligations under the plan or program. (2) Withholding. The sub recipient(s), shall upon written request of the EPA Award Official or an authorized representative of the DOL, withhold or cause to be withheld from the contractor under this contract or any other Federal contract with the same prime contractor, or any other federally-assisted contract subject to DB prevailing wage requirements, which is held by the same prime contractor, so much of the accrued payments or advances as may be considered necessary to pay laborers and mechanics, including apprentices, trainees, and helpers, employed by the contractor or any subcontractor the full amount of wages required by the contract. In the event of failure to pay any laborer or mechanic, including any apprentice, trainee, or helper, employed or working on the site of the work, all or part of the wages required by the contract, the EPA may, after written notice to the contractor, sponsor, applicant, or owner, take such action as may be necessary to cause the suspension of any further payment, advance, or guarantee of funds until such violations have ceased. (3) Payrolls and basic records. (i) Payrolls and basic records relating thereto shall be maintained by the contractor during the course of the work and preserved for a period of three years thereafter for all laborers and mechanics working at the site of the work. Such records shall contain the name, address, and social security number of each such worker, his or her correct classification, hourly rates of wages paid (including rates of contributions or costs anticipated for bona fide fringe benefits or cash equivalents thereof of the types described in section 1(b)(2)(B) of the DB Act), daily and weekly number of hours worked, deductions made and actual wages paid. Whenever the Secretary of Labor MARCH 2026 SECTION 00 74 00 2026 WATER METER INSTALLATION PROJECT GRANT CONDITIONS 4 has found under 29 CFR 5.5(a)(1)(iv) that the wages of any laborer or mechanic include the amount of any costs reasonably anticipated in providing benefits under a plan or program described in section 1(b)(2)(B) of the DB Act, the contractor shall maintain records which show that the commitment to provide such benefits is enforceable, that the plan or program is financially responsible, and that the plan or program has been communicated in writing to the laborers or mechanics affected, and records which show the costs anticipated or the actual cost incurred in providing such benefits. Contractors employing apprentices or trainees under approved programs shall maintain written evidence of the registration of apprenticeship programs and certification of trainee programs, the registration of the apprentices and trainees, and the ratios and wage rates prescribed in the applicable programs. (ii)(A) The contractor shall submit weekly, for each week in which any contract work is performed, a copy of all payrolls to the sub recipient, that is, the entity that receives the sub-grant or loan from the State capitalization grant recipient. Such documentation shall be available on request of the State recipient or EPA. As to each payroll copy received, the sub recipient shall provide written confirmation in a form satisfactory to the State indicating whether or not the project is in compliance with the requirements of 29 CFR 5.5(a)(1) based on the most recent payroll copies for the specified week. The payrolls shall set out accurately and completely all of the information required to be maintained under 29 CFR 5.5(a)(3)(i), except that full social security numbers and home addresses shall not be included on the weekly payrolls. Instead, the payrolls shall only need to include an individually identifying number for each employee (e.g., the last four digits of the employee's social security number). The required weekly payroll information may be submitted in any form desired. Optional Form WH-347 is available for this purpose from the Wage and Hour Division website at http://www.dol.gov/whd/forms/wh347instr.htm or its successor site. The prime contractor is responsible for the submission of copies of payrolls by all subcontractors. Contractors and subcontractors shall maintain the full social security number and current address of each covered worker and shall provide them upon request to the sub recipient(s) for transmission to the State or EPA if requested by EPA, the State, the contractor, or the Wage and Hour Division of the DOL for purposes of an investigation or audit of compliance with prevailing wage requirements. It is not a violation of this section for a prime contractor to require a subcontractor to provide addresses and social security numbers to the prime contractor for its own records, without weekly submission to the sub recipient(s). (B) Each payroll submitted shall be accompanied by a "Statement of Compliance," signed by the contractor or subcontractor or his or her agent who pays or supervises the payment of the persons employed under the contract and shall certify the following: (1) That the payroll for the payroll period contains the information required to be provided under§ 5.5 (a)(3)(ii) of Regulations, 29 CFR part 5, the appropriate information is being maintained under§ 5.5 (a)(3)(i) of MARCH 2026 SECTION 00 74 00 2026 WATER METER INSTALLATION PROJECT GRANT CONDITIONS 5 Regulations, 29 CFR part 5, and that such information is correct and complete; (2) That each laborer or mechanic (including each helper, apprentice, and trainee) employed on the contract during the payroll period has been paid the full weekly wages earned, without rebate, either directly or indirectly, and that no deductions have been made either directly or indirectly from the full wages earned, other than permissible deductions as set forth in Regulations, 29 CFR part 3; (3) That each laborer or mechanic has been paid not less than the applicable wage rates and fringe benefits or cash equivalents for the classification of work performed, as specified in the applicable wage determination incorporated into the contract. (C) The weekly submission of a properly executed certification set forth on the reverse side of Optional Form WH-347 shall satisfy the requirement for submission of the "Statement of Compliance" required by paragraph (a)(3)(ii)(B) of this section. (D) The falsification of any of the above certifications may subject the contractor or subcontractor to civil or criminal prosecution under section 1001 of title 18 and section 231 of title 31 of the United States Code. (iii) The contractor or subcontractor shall make the records required under paragraph (a)(3)(i) of this section available for inspection, copying, or transcription by authorized representatives of the State, EPA or the DOL, and shall permit such representatives to interview employees during working hours on the job. If the contractor or subcontractor fails to submit the required records or to make them available, the EPA or State may, after written notice to the contractor, sponsor, applicant, or owner, tak e such action as may be necessary to cause the suspension of any further payment, advance, or guarantee of funds. Furthermore, failure to submit the required records upon request or to make such records available may be grounds for debarment action pursuant to 29 CFR 5.12. (4) Apprentices and trainees (i) Apprentices. Apprentices will be permitted to work at less than the predetermined rate for the work they performed when they are employed pursuant to and individually registered in a bona fide apprenticeship program registered with the DOL, Employment and Training Administration, Office of Apprenticeship Training, Employer and Labor Services, or with a State Apprenticeship Agency recognized by the Office, or if a person is employed in his or her first 90 days of probationary employment as an apprentice in such an apprenticeship program, who is not individually registered in the program, but who has been certified by the Office of Apprenticeship Training, Employer and Labor Services or a State Apprenticeship Agency (where appropriate) to be eligible for probationary employment as an apprentice. The allowable ratio of apprentices to journeymen on the job site in any craft classification shall not be greater than the ratio permitted to the contractor as to the entire work force under the registered program. Any worker listed on a payroll at an apprentice wage rate, who is not registered or otherwise employed as stated MARCH 2026 SECTION 00 74 00 2026 WATER METER INSTALLATION PROJECT GRANT CONDITIONS 6 above, shall be paid not less than the applicable wage rate on the wage determination for the classification of work actually performed. In addition, any apprentice performing work on the job site in excess of the ratio permitted under the registered program shall be paid not less than the applicable wage rate on the wage determination for the work actually performed. Where a contractor is performing construction on a project in a locality other than that in which its program is registered, the ratios and wage rates (expressed in percentages of the journeyman's hourly rate) specified in the contractor's or subcontractor's registered program shall be observed. Every apprentice must be paid at not less than the rate specified in the registered program for the apprentice's level of progress, expressed as a percentage of the journeymen hourly rate specified in the applicable wage determination. Apprentices shall be paid fringe benefits in accordance with the provisions of the apprenticeship program. If the apprenticeship program does not specify fringe benefits, apprentices must be paid the full amount of fringe benefits listed on the wage determination for the applicable classification. If the Administrator determines that a different practice prevails for the applicable apprentice classification, fringes shall be paid in accordance with that determination. In the event the Office of Apprenticeship Training, Employer and Labor Services, or a State Apprenticeship Agency recognized by the Office, withdraws approval of an apprenticeship program, the contractor will no longer be permitted to utilize apprentices at less than the applicable predetermined rate for the work performed until an acceptable program is approved. (ii) Trainees. Except as provided in 29 CFR 5.16, trainees will not be permitted to work at less than the predetermined rate for the work performed unless they are employed pursuant to and individually registered in a program which has received prior approval, evidenced by formal certification by the DOL, Employment and Training Administration. The ratio of trainees to journeymen on the job site shall not be greater than permitted under the plan approved by the Employment and Training Administration. Every trainee must be paid at not less than the rate specified in the approved program for the trainee's level of progress, expressed as a percentage of the journeyman hourly rate specified in the applicable wage determination. Trainees shall be paid fringe benefits in accordance with the provisions of the trainee program.

The Offeror's or Bidder's attention is called to the "Equal Opportunity Clause" and the "Standard Federal Equal Employment Specifications" set forth herein. 2. The goals and timetables for minority and female participation, expressed in percentage terms for the CONTRACTOR's aggregate workforce in each trade on all construction work in the covered area, are as follows: Time- Goals for minority participation Goals for female participation tables for each trade for each trade MARCH 2026 SECTION 00 74 00 2026 WATER METER INSTALLATION PROJECT GRANT CONDITIONS 15 Within Contract Time 14.3% (El Dorado Co.) 6.9% Per Section 00 72 00 The Office of Federal Contract Compliance Programs' web site for compliance issues and preaward registry is at http://www.dol.gov/esa/welcome. These goals are applicable to all the CONTRACTOR's construction work (whether or not it is Federal or federally assisted) performed in the covered area. If the CONTRACTOR performs construction work in a geographical area located outside of the covered area, it shall apply the goals established for such geographical area where the work is actually performed. With regard to this second area, the CONTRACTOR also is subject to the goals for both its federally involved and non-federally involved construction. The CONTRACTOR's compliance with the Executive Order and the regulations in 41 CFR Part 60 4 shall be based on its implementation of the Equal Opportunity Clause, specific affirmative action obligations required by the specifications set forth in 41 CFR 60 4.3(a), and its efforts to meet the goals. The hours of minority and female employment and training must be substantially uniform throughout the length of the contract, and in each trade, and the CONTRACTOR shall make a good faith effort to employ minorities and women evenly on each of its projects. The transfer of minority or female employees or trainees from CONTRACTOR to CONTRACTOR or from project to project for the sole purpose of meeting the CONTRACTOR's goals shall be a violation of the contract, the Executive Order and the regulations in 41 CFR Part 60 4. Compliance with the goals will be measured against the total work hours performed. 3. The CONTRACTOR shall provide written notification to the Director of the Office of Federal Contract Compliance Programs (notify the applicable Regional Office found at www.dol.gov/esa) within 10 working days of award of any construction subcontract in excess of$10,000 at any tier for construction work under the contract resulting from this solicitation. The notification shall list the name, address and telephone number of the subcontractor; employer identification number of the subcontractor; estimated dollar amount of the subcontract; estimated starting and completion dates of the subcontract; and the geographical area in which the subcontract is to be performed. 4. As used in this Notice, and in the contract resulting from this solicitation, the "covered area" is (insert description of the geographical areas where the contract is to be performed giving the state, county and city, if any). § 60 4.3 Equal opportunity clauses (in relevant part) Standard Federal Equal Employment Opportunity Construction Contract Specifications (Executive Order 11246) 1. As used in these specifications: a. "Covered area" means the geographical area described in the solicitation from which this contract resulted; MARCH 2026 SECTION 00 74 00 2026 WATER METER INSTALLATION PROJECT GRANT CONDITIONS 16 b. "Director" means Director, Office of Federal Contract Compliance Programs, United States Department of Labor, or any person to whom the Director delegates authority; c. "Employer identification number" means the Federal Social Security number used on the Employer's Quarterly Federal Tax Return, U.S. Treasury Department Form 941. d. "Minority" includes: 1) Black (all persons having origins in any of the Black African racial groups not of Hispanic origin); 2) Hispanic (all persons of Mexican, Puerto Rican, Cuban, Central or South American or other Spanish Culture or origin, regardless of race); 3) Asian and Pacific Islander (all persons having origins in any of the original peoples of the Far East, Southeast Asia, the Indian Subcontinent, or the Pacific Islands); and 4) American Indian or Alaskan Native (all persons having origins in any of the original peoples of North America and maintaining identifiable tribal affiliations through membership and participation or community identification). 5. Whenever the CONTRACTOR, or any Subcontractor at any tier, subcontracts a portion of the work involving any construction trade, it shall physically include in each subcontract in excess of$10,000 the provisions of these specifications and the Notice which contains the applicable goals for minority and female participation and which is set forth in the solicitations from which this contract resulted. 6. If the CONTRACTOR is participating (pursuant to 41 CFR 60 4.5) in a Hometown Plan approved by the U.S. Department of Labor in the covered area either individually or through an association, its affirmative action obligations on all work in the Plan area (including goals and timetables) shall be in accordance with that Plan for those trades which have unions participating in the Plan. CONTRACTORs must be able to demonstrate their participation in and compliance with the provisions of any such Hometown Plan. Each CONTRACTOR or Subcontractor participating in an approved Plan is individually required to comply with its obligations under the EEO clause, and to make a good faith effort to achieve each goal under the Plan in each trade in which it has employees. The overall good faith performance by other CONTRACTORs or Subcontractors toward a goal in an approved Plan does not excuse any covered CONTRACTOR's or Subcontractor's failure to take good faith efforts to achieve the Plan goals and timetables. 7. The CONTRACTOR shall implement the specific affirmative action standards provided in paragraphs 7 a through p of these specifications. The goals set forth in the solicitation from which this contract resulted are expressed as percentages of the total hours of employment and training of minority and female utilization the CONTRACTOR should reasonably be able to achieve in each construction trade in which it has employees in the covered area. Covered Construction CONTRACTORs performing construction work in geographical areas where they do not have a Federal or federally assisted construction contract shall apply the minority and female goals established for the geographical area where the work is being performed. Goals are published periodically in the Federal Register in notice form, and such notices may be MARCH 2026 SECTION 00 74 00 2026 WATER METER INSTALLATION PROJECT GRANT CONDITIONS 17 obtained from any Office of Federal Contract Compliance Programs office or from Federal procurement contracting officers. The CONTRACTOR is expected to make substantially uniform progress in meeting its goals in each craft during the period specified. 8. Neither the provisions of any collective bargaining agreement, nor the failure by a union with whom the CONTRACTOR has a collective bargaining agreement, to refer either minorities or women shall excuse the CONTRACTOR's obligations under these specifications, Executive Order 11246, or the regulations promulgated pursuant thereto. 9. In order for the non-working training hours of apprentices and trainees to be counted in meeting the goals, such apprentices and trainees must be employed by the CONTRACTOR during the training period, and the CONTRACTOR must have made a commitment to employ the apprentices and trainees at the completion of their training, subject to the availability of employment opportunities. Trainees must be trained pursuant to training programs approved by the U.S. Department of Labor. 10. The CONTRACTOR shall take specific affirmative action's to ensure equal employment opportunity. The evaluation of the CONTRACTOR's compliance with these specifications shall be based upon its effort to achieve maximum results from its actions. The CONTRACTOR shall document these efforts fully, and shall implement affirmative action steps at least as extensive as the following: e.

Provide immediate written notification to the Director when the union or unions with which the CONTRACTOR has a collective bargaining agreement has not referred to the CONTRACTOR a minority person or woman sent by the CONTRACTOR, or when the CONTRACTOR has MARCH 2026 SECTION 00 74 00 2026 WATER METER INSTALLATION PROJECT GRANT CONDITIONS 18 other information that the union referral process has impeded the CONTRACTOR's efforts to meet its obligations. i. Develop on the job training opportunities and/or participate in training programs for the area which expressly include minorities and women, including upgrading programs and apprenticeship and trainee programs relevant to the CONTRACTOR's employment needs, especially those programs funded or approved by the Department of Labor. The CONTRACTOR shall provide notice of these programs to the sources compiled under 7b above. j. Disseminate the CONTRACTOR's EEO policy by providing notice of the policy to unions and training programs and requesting their cooperation in assisting the CONTRACTOR in meeting its EEO obligations; by including it in any policy manual and collective bargaining agreement; by publicizing it in the company newspaper, annual report, etc.; by specific review of the policy with all management personnel and with all minority and female employees at least once a year; and by posting the company EEO policy on bulletin boards accessible to all employees at each location where construction work is performed. k.

Ensure that seniority practices, job classifications, work assignments and other personnel practices, do not have a discriminatory effect by continually monitoring all personnel and employment related activities to ensure that the EEO policy and the CONTRACTOR's obligations under these specifications are being carried out. r. Ensure that all facilities and company activities are Non-Segregated except that separate or single user toilet and necessary changing facilities shall be provided to assure privacy between the sexes. s. Document and maintain a record of all solicitations of offers for subcontracts from minority and female construction CONTRACTORs and suppliers, including circulation of solicitations to minority and female CONTRACTOR associations and other business associations. t. Conduct a review, at least annually, of all supervisors' adherence to and performance under the CONTRACTOR's EEO policies and affirmative action obligations. 11. CONTRACTORs are encouraged to participate in voluntary associations which assist in fulfilling one or more of their affirmative action obligations (7a through p). The efforts of a CONTRACTOR association, joint CONTRACTOR union, CONTRACTOR community, or other similar group of which the CONTRACTOR is a member and participant, may be asserted as fulfilling any one or more of its obligations under 7a through p of these Specifications provided that the CONTRACTOR actively participates in the group, makes every effort to assure that the group has a positive impact on the employment of minorities and women in the industry, ensures that the concrete benefits of the program are reflected in the CONTRACTOR's minority and female workforce participation, makes a good faith effort to meet its individual goals and timetables, and can provide access to documentation which demonstrates the effectiveness of actions taken on behalf of the CONTRACTOR. The obligation to comply, however, is the CONTRACTOR's and failure of such a group to fulfill an obligation shall not be a defense for the CONTRACTOR's noncompliance. 12. A single goal for minorities and a separate single goal for women have been established. The CONTRACTOR, however, is required to provide equal employment opportunity and to take affirmative action for all minority groups, both male and female, and all women, both minority and non minority. Consequently, the CONTRACTOR may be in violation of the Executive Order if a particular group is employed in a substantially disparate manner (for example, even though the CONTRACTOR has achieved its goals for women generally, the CONTRACTOR may be in violation of the Executive Order if a specific minority group of women is underutilized). 13. The CONTRACTOR shall not use the goals and timetables or affirmative action standards to discriminate against any person because of race, color, religion, sex, or national origin. 14. The CONTRACTOR shall not enter into any Subcontract with any person or firm debarred from Government contracts pursuant to Executive Order 11246. 15. The CONTRACTOR shall carry out such sanctions and penalties for violation of these specifications and of the Equal Opportunity Clause, including suspension, termination and cancellation of existing subcontracts as may be MARCH 2026 SECTION 00 74 00 2026 WATER METER INSTALLATION PROJECT GRANT CONDITIONS 20 imposed or ordered pursuant to Executive Order 11246, as amended, and its implementing regulations, by the Office of Federal Contract Compliance Programs. Any CONTRACTOR who fails to carry out such sanctions and penalties shall be in violation of these specifications and Executive Order 11246, as amended. 16. The CONTRACTOR, in fulfilling its obligations under these specifications, shall implement specific affirmative action steps, at least as extensive as those standards prescribed in paragraph 7 of these specifications, so as to achieve maximum results from its efforts to ensure equal employment opportunity. If the CONTRACTOR fails to comply with the requirements of the Executive Order, the implementing regulations, or these specifications, the Director shall proceed in accordance with 41 CFR 60 4.8. 17. The CONTRACTOR shall designate a responsible official to monitor all employment related activity to ensure that the company EEO policy is being carried out, to submit reports relating to the provisions hereof as may be required by the Government and to keep records. Records shall at least include for each employee the name, address, telephone numbers, construction trade, union affiliation if any, employee identification number when assigned, social security number, race, sex, status (e.g., mechanic, apprentice trainee, helper, or laborer), dates of changes in status, hours worked per week in the indicated trade, rate of pay, and locations at which the work was performed. Records shall be maintained in an easily understandable and retrievable form; however, to the degree that existing records satisfy this requirement, CONTRACTORs shall not be required to maintain separate records. 18. Nothing herein provided shall be construed as a limitation upon the application of other laws which establish different standards of compliance or upon the application of requirements for the hiring of local or other area residents (e.g., those under the Public Works Employment Act of 1977 and the Community Development Block Grant Program). 2.08 ELIMINATION OF SEGREGATED FACILITIES - NOTICE TO PROSPECTIVE FEDERALLY-ASSISTED CONSTRUCTION CONTRACTORS A.

Note: Executive Order (EO) 13706, Establishing Paid Sick Leave for Federal Contractors applies to all contracts subject to the Davis-Bacon Act for which the contract is awarded (and any solicitation was issued) on or after January 1, 2017. If this contract is covered by the EO, the contractor must provide employees with 1 hour of paid sick leave for every 30 hours they work, up to 56 hours of paid sick leave each year. Employees must be permitted to use paid sick leave for their own illness, injury or other health-related needs, including preventive care; to assist a family member (or person who is like family to the employee) who is ill, injured, or has other health-related needs, including preventive care; or for reasons resulting from, or to assist a family member (or person who is like family to the employee) who is a victim of, domestic violence, sexual assault, or stalking. Additional information on contractor requirements and worker protections under the EO is available at https://www.dol.gov/agencies/whd/government-contracts. Note: Executive Order 13658 generally applies to contracts subject to the Davis-Bacon Act that were awarded on or between January 1, 2015 and January 29, 2022, and that have not been renewed or extended on or after January 30, 2022. Executive Order 13658 does not apply to contracts subject only to the Davis-Bacon Related Acts regardless of when they were awarded. If a contract is subject to Executive Order 13658, the contractor must pay all covered workers at least $13.30 per hour (or the applicable wage rate listed on this wage determination, if it is higher) for all hours spent performing on the contract in 2025. The applicable Executive Order minimum wage rate will be adjusted annually. Additional information on contractor requirements and worker protections https://sam.gov/wage-determination/CA20260019/4 46/49 3/15/26, 10:43 AM SAM.gov under Executive Order 13658 is available at www.dol.gov/whd/govcontracts. Unlisted classifications needed for work not included within the scope of the classifications listed may be added after award only as provided in the labor standards contract clauses (29CFR 5.5 (a) (1) (iii)). The body of each wage determination lists the classifications and wage rates that have been found to be prevailing for the type(s) of construction and geographic area covered by the wage determination. The classifications are listed in alphabetical order under rate identifiers indicating whether the particular rate is a union rate (current union negotiated rate), a survey rate, a weighted union average rate, a state adopted rate, or a supplemental classification rate. Union Rate Identifiers A four-letter identifier beginning with characters other than ""SU"", ""UAVG"", ?SA?, or ?SC? denotes that a union rate was prevailing for that classification in the survey. Example: PLUM0198-005 07/01/2024. PLUM is an identifier of the union whose collectively bargained rate prevailed in the survey for this classification, which in this example would be Plumbers. 0198 indicates the local union number or district council number where applicable, i.e., Plumbers Local 0198. The next number, 005 in the example, is an internal number used in processing the wage determination. The date, 07/01/2024 in the example, is the effective date of the most current negotiated rate. Union prevailing wage rates are updated to reflect all changes over time that are reported to WHD in the rates in the collective bargaining agreement (CBA) governing the classification. Union Average Rate Identifiers The UAVG identifier indicates that no single rate prevailed for those classifications, but that 100% of the data reported for the classifications reflected union rates. EXAMPLE: UAVG-OH-0010 01/01/2024. UAVG indicates that the rate is a weighted union average rate. OH indicates the State of Ohio. The next number, 0010 in the example, is an internal number used in producing the wage determination. The date, 01/01/2024 in the example, indicates the date the wage determination was updated to reflect the most current union average rate. A UAVG rate will be updated once a year, usually in January, to reflect a weighted average of the current rates in the collective bargaining agreements on which the rate is based. Survey Rate Identifiers The ""SU"" identifier indicates that either a single non-union rate prevailed (as defined in 29 CFR 1.2) for this classification in the survey or that the rate was derived by computing a weighted average rate based on all the rates reported in the survey for that classification. As a weighted average rate includes all rates reported in the survey, it may include both union and non-union rates. Example: SUFL2022-007 https://sam.gov/wage-determination/CA20260019/4 47/49 3/15/26, 10:43 AM SAM.gov 6/27/2024. SU indicates the rate is a single non-union prevailing rate or a weighted average of survey data for that classification. FL indicates the State of Florida. 2022 is the year of the survey on which these classifications and rates are based. The next number, 007 in the example, is an internal number used in producing the wage determination. The date, 6/27/2024 in the example, indicates the survey completion date for the classifications and rates under that identifier. ?SU? wage rates typically remain in effect until a new survey is conducted. However, the Wage and Hour Division (WHD) has the discretion to update such rates under 29 CFR 1.6(c)(1). State Adopted Rate Identifiers The ""SA"" identifier indicates that the classifications and prevailing wage rates set by a state (or local) government were adopted under 29 C.F.R 1.3(g)-(h). Example: SAME2O23-007 01/03/2024. SA reflects that the rates are state adopted. ME refers to the State of Maine. 2023 is the year during which the state completed the survey on which the listed classifications and rates are based. The next number, 007 in the example, is an internal number used in producing the wage determination. The date, 01/03/2024 in the example, reflects the date on which the classifications and rates under the ?SA? identifier took effect under state law in the state from which the rates were adopted. WAGE DETERMINATION APPEALS PROCESS 1) Has there been an initial decision in the matter? This can be: a) a survey underlying a wage determination b) an existing published wage determination c) an initial WHD letter setting forth a position on a wage determination matter d) an initial conformance (additional classification and rate) determination On survey related matters, initial contact, including requests for summaries of surveys, should be directed to the WHD Branch of Wage Surveys.

The Engineer may at any time, by notice in writing to the Contractor, suspend any part of the work for such period of time as may be necessary to prevent improper execution of the work on the project by the Contractor, its Subcontractors or agents, and the Contractor shall have no claim for damages or additional compensation on account of any such suspension. B. The District may at any time suspend any part or all of the work upon ten (10) days written notice to the Contractor, who shall immediately discontinue all work suspended except for all operations to prevent loss or damage to work already executed as may be directed by the Engineer. In the event a part of the work is suspended, the Contractor, if the suspension is not through his MARCH 2026 SECTION 01 35 00 2026 WATER METER INSTALLATION PROJECT SPECIAL PROCEDURES 1 fault or the fault of its Subcontractors or agents, shall be paid on the same basis as Extra Work for costs of work performed in accordance with such orders of the Engineer during such suspension, provided that this shall not include any cost pertaining to work not suspended by said notice. Work shall be resumed by the Contractor after such suspension on written notice from the District. In the event of suspension of the entire work by the District, the Contractor, if the suspension is not through fault of the Contractor or the fault of his Subcontractors or agents, shall be paid the sum of$500.00 for each calendar day during which the entire work shall have been suspended. This amount is fixed as liquidated damages in full settlement of all costs and expenses, losses, and damages resulting to the Contractor from such suspension. The parties expressly agree that it is impractical to determine the actual amount of damage to Contractor by reason of such delay and that this liquidated damages clause is reasonable under the circumstances existing at the time the Contract was made. Work shall be resumed by the Contractor after such suspension on written notice from the District. C. In the event of any suspension of the work in whole or in part B above, the Contractor shall be entitled to an extension of time to complete the work to the extent of the delay caused to the Contractor.

MARCH 2026 SECTION 01 35 00 2026 WATER METER INSTALLATION PROJECT SPECIAL PROCEDURES 2 B. The Contractor shall at all times employ such force, labor plant, materials, and tools as will be sufficient, in the opinion of the Engineer, to prosecute the work at not less than the rate provided in the progress schedule and to complete the work within the time limits fixed by the Contract. C. The District may, after giving ten (10) days written notice to the Contractor, terminate its right to proceed with the work or such part of the work as to which there has been delay. The notice of intent to terminate shall contain the reasons for such intention to terminate. D. The Contractor's right to proceed shall not be so terminated nor the Contractor charged with resulting damage if: 1. The delay in the completion of the work arises from unforeseeable causes beyond the control and without the fault or negligence of the Contractor, including but not restricted to Acts of God, acts of the public enemy, acts of the District, acts of another contractor in the performance of a Contract with the District, fires, floods, excluding site flooding due to groundwater, epidemics, quarantine restrictions, strikes, lockouts, freight embargoes, unusually severe weather, or delays of subcontractors and suppliers arising from unforeseeable causes beyond the control and without the fault or negligence of either the Contractor or such subcontractors and suppliers; and 2. The Contractor, within ten (10) days from the beginning of any such delay (unless the Engineer grants further period of time before the date of final payment under the Contract), notifies the Engineer in writing of the causes of delay and requests an extension of time. E. The Engineer shall ascertain the facts and the extent of the delay and extend the time for completing the work when, in the Engineer's judgment, the findings of fact justify such an extension, and the findings of fact shall be final and conclusive on the parties. F. A request for an extension of time, or the granting of an extension of time, shall not constitute a basis for any claim against the District for additional compensation or damages unless caused by the District or another contractor employed by the District. G. If the Contractor should be adjudged bankrupt, or if he should make a general assignment for the benefit of creditors, or if a receiver should be appointed for the Contractor on account of insolvency and not be discharged within ten (10) days after his appointment, or if the Contractor fails to make prompt payments to subcontractors or suppliers, or should he persistently disregard laws, ordinances, or the instructions of the Engineer, or otherwise commit a material breach of any provisions of the Contract, the District may, after giving ten (10) days written notice to the Contractor, terminate the Contract and the Contractor's right to proceed with the work. H. The rights and remedies of the District provided in this section are in addition to any of the rights and remedies provided by law or under this Contract. MARCH 2026 SECTION 01 35 00 2026 WATER METER INSTALLATION PROJECT SPECIAL PROCEDURES 3 I. In addition to the District's rights under this section, if at any time before completion of the work under the Contract, it shall be determined by the District that reasons beyond the control of the parties render it impossible or against the interests of the District to complete the work, or if the work shall be stopped by an injunction of a court of competent jurisdiction or by order of any competent authority, the District may, upon ten (10) days written notice to the Contractor, discontinue the work and terminate the Contract. Upon service of such notice of termination, the Contractor shall discontinue the work in such manner, sequence, and at such times as the Engineer may direct. The Contractor shall have no claim for damages for such discontinuance or termination, nor any claim for anticipated profits on the work thus dispensed with, nor any other claim except for the work actually performed up to the time of discontinuance, including the cost of materials and equipment on hand, in transit, or on definite commitment and any extra work ordered by the Engineer to be done, nor for any claim for liquidated damages in accordance with the provisions of Part 2.03. The value of the work performed and the cost of materials and equipment delivered to the site will be determined by the Engineer in accordance with the procedure prescribed for the making of the final application for payment. The Contractor shall assign to the District, as directed by the Engineer, all right, title, and interest of the Contractor under the subcontracts terminated, in which case the District shall have the right to settle or to pay any termination settlement proposal arising out of those terminations. As directed by the Engineer, the Contractor shall transfer title and deliver to the District: 1. the fabricated or unfabricated parts, work-in-progress, completed work, supplies, and other materials produced or acquired for the work terminated; and 2. the completed or partially completed plans, drawings, information, and other property that, if the Contract had been completed, would be required to be furnished to the District. 2.05 RIGHTS OF DISTRICT UPON TERMINATION A. In the event the right of the Contractor to proceed with the work, or any portion thereof, has been terminated because of the fault of the Contractor and the Contractor has been given ten (10) days notice to cure such fault and has not done so, the District may issue a notice of termination to the Contractor and the Contractor's surety. B. Upon termination the Contractor shall not be entitled to receive any further payment until the work is finished. If upon completion of the work the total cost to the District, including engineering, legal, and other consultant fees, costs of managerial and administrative services, construction costs, and liquidated damages shall be less than the amount which would have been paid if the work had been completed by the Contractor in accordance with the terms of the Contract, then the difference shall be paid to the Contractor in the same manner as the final payment under the Contract. If the total cost incurred by the District on account of termination of the Contract and subsequent completion of the work by the District by whatever method the District may deem expedient shall exceed said amount which the Contractor MARCH 2026 SECTION 01 35 00 2026 WATER METER INSTALLATION PROJECT SPECIAL PROCEDURES 4 would otherwise have been paid, the Contractor and his sureties shall be liable to the District for the full amount of such excess expense. C. Upon termination, if the District takes over the Work, the District may, without liability for so doing, take possession of and utilize in completing the Work such materials, appliances, plant, and other property belonging to the Contractor as may be left on the Project site. D. The rights and remedies of the District provided in this Section are in addition to any of the rights and remedies provided by law or under this Contract. 2.06 FAILURE TO COMPLETE THE WORK IN THE TIME AGREED UPON; LIQUIDATED DAMAGES A. Liquidated Damages -In case all the work is not completed before or upon the expiration of the time limit as set in the Bid, Contract, and Progress Schedule, or within any time extensions that may have been granted, substantial damage will be sustained by the District; it is impracticable to determine the actual amount of damage by reason of such delay. It is, therefore, agreed that the Contractor and its Surety shall be liable for and pay to the District as damages, and not as a penalty, the amount specified in Section 00 72 00, General Conditions, for each and every day's delay in finishing the work in excess of the number of days specified. The parties expressly agree that this liquidated damage clause is reasonable under the circumstances existing at the time the Contract was made. B. In addition to liquidated damages for delay, if the delay results in the imposition of regulatory fines for late performance, it is agreed that the Contractor and its Surety shall be liable for and pay to the District as damages, and not as a penalty, the liquidated amount specified in Section 00 72 00. C. Exclusions - Notwithstanding the provisions above, the Contractor shall not be liable for liquidated damages or delays caused by the removal or relocation of utilities when such removal or relocation is the responsibility of the District or the owner of the utility under Government Code Section 4215. 2.07 RESPONSIBILITY FOR REPAIR OF FACILITIES A.

PART 3 EXECUTION 3.01 GENERAL A. It is the intent of this Specification to secure for every part of the Work concrete and grout of homogeneous structure, which when hardened will have the required strength, watertightness, and resistance to weathering. MARCH 2026 SECTION 03 30 00 2026 WATER METER INSTALLATION PROJECT CAST-IN-PLACE CONCRETE 7 B. It is recognized that some surface hairline cracks and crazing will develop in the concrete surfaces. Construction, contraction, and expansion joints have been positioned in structures, and curing methods specified, for the purpose of reducing the number and size of these expected cracks, due to the normal expansion and contraction expected from the specified concrete mixes. Class A and Class B concrete shall be watertight. Cracks which develop in walls or slabs shall be repaired. Cracks which show any signs of leakage shall be repaired until all leakage is stopped. C. Pipes, anchor bolts, steps, reglets, castings, and other inserts, as indicated on the Plans or as required, shall be encased in the concrete. Dovetail anchors or ties shall be used in conjunction with the slots or inserts for the various materials as specified under their respective sections and as may be necessary for the required work. 3.02 JOINTS AND BONDING A. As far as practicable the concrete work shall be constructed as a monolith. The locations of contraction, construction, and other joints are indicated on the Plans or specified herein. Where not specified or indicated otherwise, all slabs and walls shall have construction joints at intervals not greater than 30'. In order to preserve the strength and watertightness of the structures, no other joints shall be made except as the Engineer may authorize. At construction joints, the concrete in place shall be thoroughly cleaned of laitance, grease, oil, mud, dirt, curing compounds, mortar droppings, or other objectionable matter by means of a bush hammer or heavy sandblasting, after which the surfaces shall be washed just prior to the succeeding concrete placement. Immediately prior to resuming concrete placing operations, a bed of grout not less than 2" in thickness nor more than 1" in thickness shall be thoroughly spread over the horizontal joint surfaces. Keyways in joints shall be provided as indicated on the Plans. Material for keyways shall be steel, plastic or lumber treated with form release coating, applied in accordance with the manufacturer's published instructions. B. Construction joints shall be washed free of sawdust, chips, and other debris after forms are built and immediately before the concrete placement. Should formwork confine sawdust, chips, or other loose matter in such a manner that it is impossible to remove them by flushing with water, a vacuum cleaner shall be used for their removal, after which the cleaned surfaces shall be flushed with water. A cleanout hole shall be provided at the base of each wall and column for inspection and cleaning. C. In any case where it is necessary to repair concrete by bonding mortar or new concrete to concrete which has reached its initial set, the surface of the set concrete shall first be coated with epoxy bonding agent Concressive No. 1001 LPL as manufactured by Adhesive Engineering; Sikadur Hi-Mod as manufactured by Sika Chemical Corporation; or equal. This material shall be applied in accordance with the manufacturer's published instructions. Bonding agent will not be required for filling form tie holes or for normal finishing and patching of similar sized small defects. MARCH 2026 SECTION 03 30 00 2026 WATER METER INSTALLATION PROJECT CAST-IN-PLACE CONCRETE 8 D. Expansion, contraction, and construction joints shall be constructed where and as indicated on the Plans. Waterstops, expansion joint material, synthetic rubber sealing compound, and other similar materials, shall be as specified elsewhere herein. E. The Contractor shall schedule the placing of concrete in such a manner as to complete any single placing operation to a construction, contraction, or expansion joint. Special care shall be taken to insure that concrete is well consolidated around and against waterstops and that waterstops are secured in the proper position. 3.03 MIXING CONCRETE A. General 1. Mixing equipment shall be subject to review and acceptance by the Engineer. Mixers may be of the stationary plant, paver, or truck mixer type. Adequate equipment and facilities shall be provided for accurate measurement and control of all materials and for readily changing the proportions of the material. 2. The mixing equipment shall be capable of combining the aggregates, cement, and water within the specified time into a thoroughly mixed and uniform mass and of discharging the mixture without segregation. 3. Concrete mixing plant and equipment shall be maintained in good working order and shall be operated at the loads, speeds, and timing recommended by the manufacturer or as specified. 4. The cement and aggregate shall be proportioned by weight. B. Machine Mixing 1. The batch plant shall be capable of controlling the delivery of all material to within 1 percent by weight of the individual material. If bulk cement is used, it shall be weighed on a separate visible scale which will accurately register the scale load at any stage of the weighing operation from zero to full capacity. 2. Cement shall not come in contact with aggregate or with water until the materials are in the mixer ready for complete mixing with all mixing water. The procedure of mixing cement with sand or with sand and coarse aggregate for delivery to the jobsite for final mixing and addition of mixing water will not be permitted. Retempering of concrete will not be permitted. The entire batch shall be discharge before recharging. The volume of the mixed material per batch shall not exceed the manufacturer's rated capacity of the mixer. 3. Mixing shall be done in batch mixers of acceptable type. Each mixer shall be equipped with a device for accurately measuring and indicating the quantity of water entering the concrete, and the operating mechanism shall be such that leakage will not occur when the valves are closed. Each mixer shall be equipped with a device for automatically measuring, indicating, and controlling the time required for mixing. This device shall be interlocked to prevent the discharge of concrete from the mixer before the expiration of the mixing period. 4. Transit-mixed concrete shall be mixed and delivered in accordance with ASTM C 94. The total elapsed time between the addition of water at the batch plant and discharging the completed mix shall not exceed 90 minutes nor shall the elapsed time at the jobsite exceed 30 minutes. Under conditions contributing to quick setting, the total elapsed time permitted may be reduced by the Engineer. Each truck mixer shall be equipped with a device for counting the MARCH 2026 SECTION 03 30 00 2026 WATER METER INSTALLATION PROJECT CAST-IN-PLACE CONCRETE 9 number of revolutions of the drum which device shall be interlocked so as to prevent the discharge of concrete from the drum before the required number of turns. After the drum is once started, it shall be revolved continuously until it has completely discharged its batch. Water shall not be admitted to the mix until the drum has started revolving. The right is reserved to increase the required minimum number of revolutions or to decrease the designated maximum number of revolutions allowed, if necessary, to obtain satisfactory mixing, and the Contractor will not be entitled to additional compensation because of such increase or decrease. 5. In the case of other types of mixers, mixing shall be as follows: The concrete shall be mixed until there is uniform distribution of the materials, and the mixer shall be discharged completely before being recharged. Neither speed nor volume loading of the mixer shall exceed the manufacturer's recommendations. Mixing shall be continued fora minimum of 1-1/2 minutes after all materials are in the drum, and for batches larger than 1 cubic yard the minimum mixing time shall be increased 15 seconds for each additional cubic yard or fraction thereof. 3.04 CONVEYING AND PLACING CONCRETE A. Concrete shall be conveyed from the mixer to the place of final deposit by methods which will prevent the separation or loss of the materials. 3.05 PLACING AND CONSOLIDATION A. General 1. No concrete shall be placed without the prior authorization of the Engineer. 2. Concrete shall not be placed until all reinforcement is securely and properly fastened in its correct position and loose form ties at construction joints have been retightened, nor until all dowels, bucks, sleeves, hangers, pipes, conduits, bolts, and any other fixtures required to be embedded therein have been placed and adequately anchored, nor until the forms have been cleaned and oiled as specified. 3. Placement of concrete in which initial set has occurred or of re-tempered concrete will not be permitted. 4. No concrete shall be placed during rainstorms or high velocity winds. Concrete placed immediately before rain shall be protected to prevent the water from coming in contact with it or winds causing excessive drying. Sufficient protective covering shall be kept on hand at all times for protection purposes. B. Placing Concrete 1. The Contractor shall prepare and submit to the Engineer for review, a proposed sequence of placing concrete showing proposed beginning and ending of individual placements. After acceptance, this sequence shall be adhered to except when specific changes are requested by the Contractor and accepted by the Engineer. The Contractor shall notify the Engineer by written memorandum of his readiness (not just his intention) to place concrete in any portion of the Work. This notification shall be such time in advance of the operation as the Engineer deems necessary for him to make final inspection of the preparations at the location of the proposed concrete placing. All forms, MARCH 2026 SECTION 03 30 00 2026 WATER METER INSTALLATION PROJECT CAST-IN-PLACE CONCRETE 10 steel, screeds, anchors, ties, and inserts shall be in place before the Contractor's notification of readiness is given to the Engineer. 2. Concrete shall be deposited at or near its final position to avoid segregation caused by rehandling or flowing. Concrete shall not be deposited in large quantities in one place and worked along the forms with the vibrator or otherwise. No concrete shall be dropped freely into place from a greater height than 5'. Tremies shall be used for placing concrete where the drop is over 5'. Placement of concrete on slopes shall commence at the bottom of the slope. 3. Concrete shall be placed in approximately horizontal layers not to exceed 24" in depth and shall be brought up evenly in all parts of the forms. Concrete placement shall continue without avoidable interruption, in a continuous operation, until the end of the placement is reached. The placement of concrete in wall forms shall not proceed at a faster rate of rise than 6 feet per hour when the temperature is 70°F or over, and at a lesser rate for lower temperatures. 4. If it takes more than 20 minutes lapse prior to placement of new concrete over concrete previously placed, the depth of the layers being placed at one time shall be reduced, and/or placing equipment increased, until it is possible to return with the placing operation to previously placed concrete within 20 minutes. If concrete is to be placed over previously placed concrete and more than 20 minutes have elapsed, then a layer of grout not less than 2" thick nor more than 1" in thickness shall be spread over the surface before placing the additional concrete. 5. The placement of concrete for slabs, beams, or walkways cast monolithically with walls or columns shall not commence until the concrete in the walls or columns has been allowed to set and shrink. The time allowed for shrinkage shall be not less than one hour. C. Consolidating Concrete 1. Concrete shall be placed with the aid of acceptable mechanical vibrators. Vibration shall be supplemented by manual forking or spading adjacent to the forms on exposed faces in order to secure smooth dense surfaces. The concrete shall be thoroughly consolidated around reinforcement, pipes, or other shapes built into the work. The vibration shall be sufficiently intense to cause the concrete to flow and settle readily into place and to visibly affect the concrete over a radius of a least 18". 2. Sufficient vibrators shall be on hand at all times to vibrate the concrete as placed. In addition to the vibrators in actual use while concrete is being placed, the Contractor shall have on hand one spare vibrator in serviceable condition. No concrete shall be placed until it has been ascertained that all vibrating equipment, including spares, is in serviceable condition. 3. Special care shall be taken to place the concrete solidly against the forms to leave no voids. Every precaution shall be taken to make all concrete solid, compact, and smooth, and if for any reason the surfaces or interiors have voids or are in any way defective, such concrete shall be repaired in a manner acceptable to the Engineer. D. Requirements For Extreme Weather Conditions 1. For concrete placed when the ambient air temperature is above 90°F, the forms and reinforcing steel shall be cooled to below 90°F by water spraying. MARCH 2026 SECTION 03 30 00 2026 WATER METER INSTALLATION PROJECT CAST-IN-PLACE CONCRETE 11 The temperature of the concrete mix at time of placement shall be kept below 90°F by means possible which do not impair the quality of the concrete. 2. The Contractor shall secure the Engineer's acceptance for type of equipment to be used for heating materials and/or new concrete in the process of curing during excessively cold weather. For concrete placed below an ambient air temperature of 40°F, or 45°F and falling, provision shall be made for heating the water. If materials have been exposed to freezing temperatures to the degree that any material is below 35°F, the material shall be heated. Water, cement, or aggregate materials shall not be heated in excess of 160°F. Concrete in the forms shall be protected by means of covering with tarpaulins, or other acceptable covering, and a means shall be provided for circulating warm moist air around the forms to maintain a temperature of 50°F for at least five days. 3. For conditions which promote rapid drying of freshly placed concrete such as low humidity, high temperature, and wind, the Contractor shall take corrective measures to minimize the rapid water loss from the concrete. The Contractor shall submit the corrective measures he plans to use for review and acceptance by the Engineer prior to placing concrete. 4. The Contractor shall provide and use a sufficient number of maximum and minimum self-recording thermometers to adequately indicate the temperature around the concrete. 3.06 FOOTINGS AND SLABS ON GRADE A. Concrete to be placed on ground or compacted fill shall not be placed until the subgrade is in a moist condition acceptable to the Engineer. If necessary, the subgrade shall be well sprinkled with water not less than 6 nor more than 20 hours in advance of placing concrete. If it becomes dry prior to the actual placing of concrete, it shall be sprinkled again, without forming pools of water. No concrete shall be placed if the subgrade is muddy or soft. 3.07 CURING CONCRETE A. GENERAL 1. All concrete shall be cured by the methods specified herein. 2. All concrete shall be cured a minimum of seven days. 3. All concrete that is to be painted shall be water or plastic membrane cured. No curing compound shall be used on any concrete surface that is to receive paint or upon which any material is to be bonded. All other concrete shall be cured by water curing or sprayed curing membrane at the Contractor's option, except floors and slabs which are specified to be sealed with a concrete sealer. Floor slabs may be cured using a plastic film membrane curing. B. WATER CURING 1. All surfaces of concrete being water cured shall be kept constantly and visibly moist day and night for a period of not less than seven days and nights. Each day the forms remain in place may count as one day of water curing. No further curing credit will be allowed for forms in place after contact has once been broken between the concrete surface and the forms. Ties shall not be loosened during the period when concrete is being cured by leaving the forms in place. The top of walls shall be flooded with water at least three times per MARCH 2026 SECTION 03 30 00 2026 WATER METER INSTALLATION PROJECT CAST-IN-PLACE CONCRETE 12 day, and the concrete surface shall be kept moist at all times during the seven day curing period. C. SPRAYED MEMBRANE CURING 1. Membrane curing compound shall be a clear type with fugitive dye conforming to ASTM C 309, Type 1 D. 2. The curing compound shall be applied to the concrete surface after repairing and patching, and within one hour after the forms are removed. If more than one hour elapses after the removal of the forms, membrane compound shall not be used and water curing shall be applied for the full curing period. If the surface requires repairing or painting, the concrete shall be water cured. 3. Curing compound shall not be removed from the concrete in less than seven days. Curing compound may be removed by the Contractor only upon written request by the Contractor and acceptance by the Engineer, stating what measures the Contractor shall take to adequately cure the structure. 4. Care shall be taken to apply curing compound in the area of construction joints to see that curing compound is placed within the construction joint silhouette. The curing compound placed within the construction joint silhouette shall be removed by sandblasting prior to placing any new concrete. The Contractor has the option of water curing the construction joint. Any curing compound shall be removed through heavy sandblasting of the joint. 5. Curing compound shall be applied by a mechanical, power-operated sprayer and mechanical agitator that will uniformly mix all pigment and compound. The compound shall be applied in at least two coats. Each coat shall be applied in a direction opposite to the preceding coat. The compound shall be applied in sufficient quantity so that the surface will have a uniform appearance and will effectively and completely conceal all natural color of the concrete at the time of the spraying. The Contractor shall continue to coat and recoat the surface until the specified coverage is achieved and until a coating film remains on the surface of the concrete. The thickness and coverage of the compound shall be such that the film can be scraped from the surface at any and all points after drying for at least 24 hours. 6. The Contractor is cautioned that the method of applying curing compound specified herein may require more compound than normally suggested by the manufacturer of the compound and also more than is customary in the trade. The amounts specified herein shall be applied, regardless of manufacturer's recommendations or customary practice, if the Contractor elects to use curing compound in place of water curing. 7. If the Contractor desires to use a curing compound other than the specified compound, the Contractor shall coat sample areas of concrete wall with the proposed compound and also a similar adjacent area with the specified compound in the specified manner for comparison. Complete data on the proposed compound shall also be submitted for review. If the proposed sample is not equal or better, in the opinion of the Engineer, in all features, the proposed substitution will not be allowed. 8. Prior to final acceptance of the work, the Contractor shall remove, by sandblasting or other acceptable method, any curing compound on surfaces that will be exposed to view, so that only the natural color of the finished concrete will be visible uniformly over the entire surface. MARCH 2026 SECTION 03 30 00 2026 WATER METER INSTALLATION PROJECT CAST-IN-PLACE CONCRETE 13 3.08 CONCRETE FINISHING A. Concrete surfaces shall be finished as indicated on the Plans and Typical Details. Where not specified or indicated on the Plans, the surfaces shall be finished as follows: Concrete surfaces which are specified or indicated to be painted, and all concrete surfaces, interior or exterior, exposed to view shall have fins removed and joints ground smooth, and shall be "sacked" with cement mortar so that all pits and holes are filled. Surfaces in open channels, basins, and similar structures, which are normally below the water surface shall have fins removed, but need not have joints ground. However, surfaces in such locations which are above the normal water surface and exposed to view shall have fins removed and joints ground smooth, and shall be "sacked" with cement mortar so that all pits and holes are filled. Concrete surfaces in closed boxes or channels where there is normally no access or passageway shall have the fins removed. All form ties shall be removed from all surfaces, and holes shall be filled after roughening with a rotohammer. B. The following surfaces shall receive a smooth steel trowel finish: floors and slabs. C. The final steel trowel finish shall be uniformly smooth and free of all irregularities. Building and machine room floors which are not to be covered with surfacing material shall be free from trowel marks. Trowel marks will be permitted in other locations. Concrete floor surfaces to which a surfacing material is to be applied shall be finished level and smooth with a tolerance of not over 1/8" in 10' in any direction. D. Edges of all control joints shall be as indicated on the Plans and Typical Details. Edges shall include any line where placement is stopped. All wall and slab surfaces at edges shall be protected against concrete spatter and shall be thoroughly cleaned upon completion of each placement. E. Where not shown otherwise on the Plans and Typical Details, all external angles of walkways, slabs, walls, beams, columns, and openings shall have a 3/4" bevel formed by utilizing a true dimensioned wood or solid plastic chamfer strip and external angles of walkways, walls, and slabs as expansion, contraction, and construction joints shall be a 2" bevel formed by utilizing a true dimensioned wood or solid plastic chamfer strip. Reentrant angles may be left square. Level strips shall be installed at the top of all wall concrete placements to maintain a true line at all horizontal construction joints. 3.09 QUALITY ASSURANCE A. TESTING OF CONCRETE 1. During the progress of construction, at the option of the Engineer, the Owner shall have tests made to determine whether the concrete, as being produced, complies with the standards of quality specified herein. These tests shall be made in accordance with ASTM C 31, ASTM C 39, and ASTM C 172. Test MARCH 2026 SECTION 03 30 00 2026 WATER METER INSTALLATION PROJECT CAST-IN-PLACE CONCRETE 14 cylinders will be made and delivered to the laboratory by the Engineer and the testing expense will be borne by the Owner. 2. Not less than three cylinder specimens, 6" x 12", will be tested for each 20 cubic yards of each grade of concrete with a minimum of three specimens for each grade placed. One cylinder will be broken at 7 days and two at 28 days. 3. The Contractor shall test the slump of concrete using a slump cone in accordance with the requirements of ASTM C 143. The Contractor shall provide the test equipment. Concrete that does not meet the Specification requirements as to slump shall not be used but shall be removed from the job. The Contractor shall test the slump at the beginning of each placement, as often as necessary to keep the slump within the specified range, and when requested to do so by the Engineer. 4. The Contractor shall make provisions for and furnish all concrete for the test specimens, and provide manual assistance to the Engineer in preparing said specimens. The Contractor shall be responsible for the care of and providing curing conditions for the test specimens in accordance with ASTM C 31. B. ENFORCEMENT OF STRENGTH REQUIREMENT 1. Concrete is expected to reach a higher compressive strength than that which is indicated in Table A as compressive strength. The strength level of the concrete will be considered satisfactory if the averages of all sets of three consecutive strength test results equal or exceed the required strength by more than 500 psi. Where an individual strength test falls below the required strength by more than 500 psi, the Engineer shall have the right to ask for additional curing of the affected portion followed by cores taken in accordance with ASTM C 42 and ACI 318, all at the Contractor's expense. If the additional curing does not bring the average of three cores taken in the affected area to at least the strength specified, the Engineer may require strengthening of the affected portions of the structures by means of additional concrete or steel or he may require replacement of these affected portions, all at the Contractor's expense. C. TOLERANCES 1. It is the intent that the finished concrete conforms to the shapes, lines, grades, and dimensions indicated on the Plans. It shall be the responsibility of the Contractor to comply with the intent of these Specifications, but it is also recognized that there will be occasions when some deviation will occur or be required. It shall therefore be agreed that the maximum deviation from true line and grade shall not exceed the tolerances listed below at the time of acceptance of the project: a. In general all tolerances shall comply with AC1 117-81, paragraphs 2.0 through 2.2 and paragraphs 4.0 through 4.5, except as modified in the following. All slabs shall be uniformly sloped to drain when a slope is indicated. Slabs which are indicated to be level shall have a maximum deviation of 1/8" in 10' without any apparent changes in grade. b. On circular tank walls, the Contractor may deviate from the finish line indicated on the Plans by the used of chord lengths not to exceed 2'. c. All inserts shall be set to the tolerances required for the proper installation and operation of the equipment or systems to which the insert pertains.

All defective work shall be removed and replaced or repaired. Any work which has not been constructed in accordance with the Plans and Specifications shall be considered defective. B. Correction of defective work shall be as specified herein. No defective work shall be patched, repaired, or covered without inspection by the Engineer. Repair shall have a strength equal or greater than the specified concrete for the area. The Contractor shall provide a mix design for the grout which is proposed for use to the Engineer for review and acceptance. All imperfections in the work shall be chipped out and keyed ready for repair. The dry pack method shall be used for holes having a depth nearly equal to or greater than the least surface dimension of the hole, for cone-bolt, and narrow slots cut for repair. Smooth holes shall be roughened with a rotohammer before repair. The mortar method of replacement shall be used for holes too wide to dry pack and too shallow for concrete replacement and shall be used for comparatively shallow depressions, large or small, which extend no deeper than the reinforcement nearest the surface. Concrete replacement shall be used when holes extend entirely through the concrete section or when holes are more than 1 square foot in area and extend halfway through the section. All surfaces of the set concrete to be repaired shall first be coated with epoxy bonding agent, Adhesive Engineering Concressive No. 1001 LPL; Sika Chemical Corporation, Sikadur Hi-Mod; or equal. No repair shall be made until the Engineer has accepted the method of preparing the surface and proposed method of repair. C. The color of the repair concrete dry pack and grout shall match that of the adjoining concrete. The use of white cement may be required to match color. The Contractor shall prepare test panels for proposed repairs at the beginning of the project for review and approval by the Engineer.

Clearing and Stripping: The Contractor shall remove all paving, subpaving, curbing, gutters, brick, paving block, granite curbing or flagging or shall grub and clear the entire surface over the areas to be excavated and shall remove and dispose of said material as required by the Specifications. In all cases, the Contractor shall machine cut in an approved width and manner all bituminous, asphaltic, and portland cement concrete pavements before stripping or excavating is begun. B. Dewatering: In accordance with Section 31 23 19 Dewatering. C. Maintaining Rights-of-Way: 1. Work shall be conducted as to cause a minimum of inconvenience to pedestrian and vehicular traffic and to private and public properties along the line of work. When specifically directed by the District, the Contractor shall complete the work in private and public rights-of-way up to a designated point MARCH 2026 SECTION 31 20 00 2026 WATER METER INSTALLATION PROJECT EARTHWORK 5 before continuing with further work in order to give required access to local facilities and property. It shall be the duty of the Contractor during the progress of the work to maintain crossings, walks, sidewalks and other roadways open to traffic in a satisfactory condition and to keep all fire hydrants, water valves, fire alarm boxes and mail boxes accessible for use. Whenever it is necessary to maintain pedestrian traffic over open trenches, safe timber bridges at least three (3) feet in width and equipped with side railings shall be provided. Where the trench is so close to the curb line that the excavated material would encroach upon the sidewalk or private property, the District may order the Contractor at the Contractor's expense to erect a plank fence together with other necessary lumber so placed to keep the sidewalk and property clear. 2. In important thoroughfares, highways or in narrow streets, the material excavated from the trench shall, if the District so directs, be removed from the site of the work at the Contractor's expense as soon as excavated in order to provide suitable space for traffic. When it is necessary to haul excavated material over the streets near the job location, the Contractor shall provide suitable type vehicles and shall promptly and thoroughly clean up all material dropped on streets and highways outside of the immediate trenching area. 3. Guard rails and other highway and street structures disturbed or altered in any way by the construction activities shall be promptly restored to a condition equal to or better than original and shall be replaced in proper alignment. Facilities discolored in anyway by the construction activities shall be refinished by the Contractor by washing and repainting as necessary. 3.02 SITE PREPARATION FOR STRUCTURAL FILLS A. All topsoil, soils with significant organics, and organic materials including vegetation shall be removed from the area receiving structural fill. B. All foundation soil which will receive structural fill shall be densified to 8 inches minimum depth, to at least 90 percent relative compaction in accordance with ASTM D1557. Immediately before this densification, soils shall have optimum moisture content, within plus or minus 2 percent, unless otherwise approved by the Engineer. C. Scarification and moisture conditioning of foundation soils may be required. D. If native foundation soils are too coarse to allow density testing (i.e., greater than 30% by weight is retained on a 3/4" sieve), then foundation soil shall be proof-rolled: 1. For mass grading, at least 5 passes with a minimum 10-ton roller. 2. For trenches, at least 5 passes with a hand compactor. E. Where boulders are encountered protruding from an excavation, they shall be removed, and the depression shall be backfilled and compacted with structural fill to meet the moisture-density requirements listed above. The terms of Part 3.04.1 shall also apply to boulder removal activities for excavations. F. Where the undisturbed condition of natural soils is inadequate for support of the planned construction, the Engineer will direct the Contractor to overexcavate to adequate supporting soils. The excavated space shall be filled to the specified MARCH 2026 SECTION 31 20 00 2026 WATER METER INSTALLATION PROJECT EARTHWORK 6 elevation with Engineered (Structural) fill in accordance with Table A- Fill Placement. The overexcavated space under footings may be filled with concrete. The quantity and placement of such material will be compensated as extra work. 3.03 FILL PLACEMENT A. Backfill shall not be dropped directly upon any structure or pipe so as to cause damage. Backfill shall not be placed around or upon any structure until the concrete has attained sufficient strength to withstand the loads imposed. Backfill around water retaining structures shall not be placed until the structures have been tested. B. Except for drain rock materials being placed in over-excavated areas or trenches, backfill shall be placed after all water is removed from the excavation. C. Fill material shall be placed in even horizontal layers and thoroughly mixed as necessary to promote uniformity of material in each layer. Pipe zone backfill materials shall be manually spread around the pipe so that when compacted the pipe zone backfill will provide uniform bearing and side support. D. Where the backfill material moisture content is below the optimum moisture content water shall be added before or during spreading until the proper moisture content is achieved. E. Where the backfill material moisture content is too high to permit the specified degree of compaction the material shall be dried until the moisture content is satisfactory. F. Material type, maximum layer depth, relative compaction, and general application are specified in Table A. G. Fill material shall be compacted with power-operated tampers, rollers, idlers, or vibratory equipment, as appropriate for the soil type and application. 1. Open-graded gravel/drain rock materials shall be compacted by means of at least two passes from a flat plate vibratory compactor. 2. Additionally, when native soil is free draining and above groundwater, pipe zone backfill materials that are granular will be compacted by mechanical means and by jetting, unless directed otherwise by the Engineer. a. Jetting: 1) The purpose of jetting is to consolidate backfill beneath the haunches of the pipe. 2) Jetting will only be performed in the portion of the trench zone from the bottom of the pipe to the top of the pipe. 3) Water is injected into backfill through a jet pipe. The next injection site will be such that each backfill layer is saturated and consolidated to its full depth before the next layer is placed. The amount of jetted water, duration of jetting at each site, and frequency of jetting will be adjusted based on field conditions and equipment used. 4) Jet pipes shall be kept at least 6 inches away from the pipe where the backfill is being consolidated and 2 feet away from other pipes or utilities. Care must be taken to ensure that the install pipe is not floated or moved during this operation. MARCH 2026 SECTION 31 20 00 2026 WATER METER INSTALLATION PROJECT EARTHWORK 7 5) If jetting is used, the pipe shall be filled with water to prevent flotation, if required by the Engineer. 6) Each layer shall not exceed 6" in thickness after compaction 3. Equipment that is consistently capable of achieving the required degree of compaction shall be used and each layer shall be compacted over its entire area while the material is at the required moisture content. 4. Equipment weighing more than 10,000 pounds shall not be used closer to walls than a horizontal distance equal to depth of the fill at that time. 5. Hand operated power compaction equipment shall be used where use of heavier equipment is impractical or restricted due to weight limitations. H. Unless otherwise specified, fill placement classes shall be used where specified in Table A under general application, in accordance with ASTM D1557. Table A, Fill Placement Maximum Minimum Moisture Fill Type uncompressed relative content, layer thickness, compaction, percent General application inches percent Aggregate Base 8 95 ± 2 of Pipe Zone Backfill (No optimum Recycled Material), Tank Floor Base; Final Backfill under pavement Engineered Fill 8 95 ±2 of Structural Fill for (Structural) optimum Foundations, Trench Zone Backfill Beneath Pavement And Under Structures Engineered Fill 12 90 ±2 of Trench Zone Backfill in (Non-Structural) optimum Unpaved Areas.

Unless otherwise specified, site fill and nonstructural fill shall be Engineered (Non- Structural) fill. If the existing slope in an area to be filled is greater than 5:1, the Contractor shall bench and key the slope prior to filling, as shown in the Drawings. 3.05 PIPELINE AND UTILITY TRENCHES A. General: 1. The Contractor shall do all excavating of whatever substance encountered to a depth as indicated on the approved plans or as specified herein. Excavated materials not required or unsuitable for backfill shall be removed from the site and disposed of by the Contractor at a site approved by TRPA. Pipe trenches shall be sufficiently straight between the designated angle points to permit the pipe to be laid true to line in the approximate center of the trench. 2. Unless otherwise shown or ordered, excavation for pipelines and utilities shall be open-cut trenches. Trench widths shall be kept as narrow as is practical for the method of pipe zone densification selected by the Contractor, but shall have a minimum width at the bottom of the trench of 24 inches for pipe 10 inches or less in diameter. For pipe greater than 10 inches but less than 18 inches, minimum trench width shall be 30 inches. The maximum width below the top of the pipe, when laid to the required grade, shall in no event exceed the outside diameter of the pipe plus twenty four inches (24"). Where sheeting and shoring are used, the maximum allowable width shall be measured between the closest interior faces of the sheeting or shoring as placed. Overall width of the excavation equipment used shall in no case exceed the maximum allowable trench width. Whenever, for any reason, the maximum allowable trench width is exceeded at the top of the pipe, the Contractor shall employ one or more of the following procedures as approved by the District: a. The pipe shall be bedded in a monolithic cradle of plain or reinforced concrete having a minimum thickness of one fourth (1/4) the inside pipe diameter or a minimum of four inches (4") under the barrel and extending up the sides for a height equal to one half(1/2) the outside diameter. The cradle shall have a width at least equal to the outside diameter of the pipe barrel plus eight inches (8"). Backfill above the crown of the pipe shall be compacted carefully. b. Provide a higher strength pipe required to withstand the increased loading on the pipe caused by the excessive trench width. c. Install temporary sheeting and shoring while the pipe is being installed with the backfill placed and compacted to a height at least one (1) foot above the top of the pipe. MARCH 2026 SECTION 31 20 00 2026 WATER METER INSTALLATION PROJECT EARTHWORK 9 B. Trench Bottom: Except when pipe bedding is required, the bottom of the trench shall be excavated uniformly to the grade of the bottom of the pipe. The trench bottom shall be given a final trim, using a string line for establishing grade, such that each pipe section when first laid will be continually in contact with the ground along the extreme bottom of the pipe. For bell and spigot pipe, the Contractor shall round out a cradle for the bell so that the bottom of the pipe is in continual contact with the bedding. Rounding out the trench to form a cradle for the pipe will not be required, except as in 3.02.A.2.a described above. C. Open Trench: The maximum amount of open trench permitted in any one location shall be 500 feet, or the length necessary to accommodate the amount of pipe installed in a single day, whichever is greater. All trenches shall be fully backfilled at the end of each day or, in lieu thereof, shall be covered by heavy steel plates adequately braced and capable of supporting vehicular traffic in roadways or smooth, continuous plywood covers suitable for carrying foot or bicycle traffic safety in unpaved areas where it is impractical to backfill at the end of each day. The above requirements for backfilling or use of steel plate or plywood covers will not be waived at any time. In addition, barricades and warning lights meeting OSHA requirements shall be provided and maintained. D. Trench Over-Excavation: Where the Drawings indicate that trenches shall be over- excavated, they shall be excavated to the depth shown, and then backfilled to the grade of the bottom of the pipe. E. Over-Excavation: When ordered by the Engineer, whether indicated on the Drawings or not, trenches shall be over-excavated beyond the depth shown. Such over-excavation shall be to the depth ordered. The trench shall then be backfilled to the grade of the bottom of the pipe. All work specified in this Section shall be performed by the Contractor when the over-excavation ordered by the Engineer is less than 6" below the limits shown. When the over-excavation ordered by the Engineer is 6" or greater below the limits shown, additional payment will be made to the Contractor for that portion of the work which is located below said 6" distance. Said additional payment will be made under separate unit price bid items for over- excavation and bedding if such bid items have been established; otherwise payment will be made in accordance with a negotiated price. F. Completion of Excavation: The Contractor shall notify the District when excavations for pipelines or utilities are completed, and no concrete shall be deposited, nor pipes installed, until the excavations have been approved by the District. G. OVER-EXCAVATION NOT ORDERED, SPECIFIED, OR SHOWN 1. Any over-excavation carried below the grade ordered, specified, or shown, shall be backfilled to the required grade with the specified material and compaction. Such Work shall be performed by the Contractor at his/her own expense. H. TRENCH BACKFILL AND COMPACTION 1. Bedding shall be provided for all pipelines. 2. After compacting the bedding, the Contractor shall perform a final trim using a stringline for establishing grade, such that each pipe section when first laid will MARCH 2026 SECTION 31 20 00 2026 WATER METER INSTALLATION PROJECT EARTHWORK 10 be continually in contact with the bedding along the extreme bottom of the pipe. 3. The pipe zone shall be backfilled with the specified backfill material. The Contractor shall exercise care to prevent damage to the pipe itself during the installation and backfill operations. 4. After the pipe zone backfill has been placed as specified above, and after all excess water has completely drained from the trench, backfilling of the trench zone may proceed. I. EXCAVATION IN LAWN AREAS 1. Where excavation occurs in lawn areas, the sod shall be carefully removed and stockpiled to preserve it for replacement. Excavated material may not, under any circumstances, be placed on the lawn. Immediately after completion of backfilling and testing of the pipeline, the sod shall be replaced in a manner so as to restore the lawn to its original condition. Contractor shall provide new sod if stockpiled sod has remained so for more than 72 hours within the scope of the Contract. Sod compressed or otherwise damaged by the Contractor's operations shall be replaced. J. EXCAVATION AND COMPACTION IN VICINITY OF TREES 1. Except where trees are shown to be removed, trees shall be protected from injury during construction operations. No tree roots over 1-1/2" in diameter shall be cut without express permission of the Engineer. Trees shall be supported during excavation by any means previously reviewed by the Engineer. 2. Where delineated on the plans, or where required for preservation of the roots, the Contractor shall provide hand excavation. Hand excavation shall be to the depth required for pipe installation, up to a depth of 5'. 3. In areas which require hand excavation, the backfill must be compacted such that tree roots 1.5" and larger are preserved. 3.06 ROCK EXCAVATION 1. Rock excavation shall include removal and disposal of the following: a. all boulders that cannot be moved using the largest piece of equipment onsite; b. all rock material in ledges, bedding deposits, and unstratified masses which cannot be removed without systematic drilling and splitting or blasting; c. concrete or masonry structures which have been abandoned; and, d. conglomerate deposits which are so firmly cemented that they possess the characteristics of solid rock and which cannot be removed without systematic drilling and splitting or blasting. 2. No rock splitting or blasting shall commence without the approval of the Engineer. 3. Said rock excavation shall be performed by the Contractor. Should the quantity of rock excavation be affected by any change in the scope of the work, an appropriate adjustment of the contract price will be made under a separate bid item if such bid item has been established; otherwise, payment will be made in accordance with a negotiated price. 4. Explosives and Blasting: MARCH 2026 SECTION 31 20 00 2026 WATER METER INSTALLATION PROJECT EARTHWORK 11 a. Blasting will not be permitted, except by express permission of the Engineer on a case-by-case basis. The use of explosives will be subject to the approval and regulations of all agencies having jurisdiction.

Section 4.1 of AWWA C651 shall be followed as written except that sodium hypochlorite is the only form of chlorine to be used for disinfection. c. Section 5.1.1 of AWWA C651 shall be followed as written except that at least two sample sets, obtained on successive days at a minimum of 24 hours apart, shall be collected from the new main and each branch. 1) A sample set consists of three samples for every 1,200 foot section of pipelines: one at the each end and one in the middle. An extra sample is needed for each additional 600 feet of pipe. 2) Water service lateral connections or dedicated sample ports should be used for sample taps. Samples must not be taken from fire hydrants, unless approved by the Engineer. 3) The sample tap should be flushed enough to clear the sample line and ensure that the sample is from the main. Sample taps should be installed at least one (1) foot above grade to prevent contamination from soil. d. A standard heterotrophic plate count (HPC) will be required. This sample will be drawn at the same time as the first sample set for coliforms. HPC must be less than 500 cfu per mL, in accordance with Section 5.1.4 of AWWA C651. 4. Disinfection and Testing Procedures: a. Charge and chlorinate the line in accordance with AWWA C651, as modified above. Record initial chlorine level in main. b. The chlorinated water shall be retained in the pipeline for at least 24- hours. If water temperature is less than 5 degrees C, the time required for the chlorinated water to remain in the pipeline shall be no less than 48-hours. c. All valves and hydrants in the treated section shall be operated during the 24-hour chlorination period to disinfect the appurtenances. d. At the end of the 24-hour period (or 48-hour period as required in Part 3.03.A.4.a, above), the treated water in all portions of the main shall be tested by District laboratory personnel and found to have a residual of not less than 10 mg/L free chlorine. e. Before the first bacteriological sample is taken, the main shall be flushed so that the total chlorine residual is no greater than that currently in the water distribution system. f. Samples for bacteriological and HPC testing shall be collected by District laboratory personnel. g. After the first sample for bacteriological testing is taken, the water will remain undisturbed in the main for 24 hours, after which, a second set of samples for bacteriological testing shall be collected by District laboratory personnel. In the event that at the time of the second bacteriological sampling the total chlorine residual is greater than that in the water distribution system, the water line will be flushed until the total chlorine residual is no greater than that of the water in the distribution system. It will be the Engineers discretion to decide whether or not water in the main must remain undisturbed for an additional 24 hours before the second bacteriological sample is taken. 5. The new main shall be approved as disinfected when all of the following have been achieved: a. All bacteriological tests on two successive days must be negative for total coliform organisms. MARCH 2026 SECTION 33 13 00 2026 WATER METER INSTALLATION PROJECT WATER PIPELINE TESTING AND DISINFECTION 4 b. HPC is found to be less than 500 cfu per mL, in accordance with Section 5.1.4. 6. Scheduling a. The time required for completing the disinfection and bacteriological testing is at least 4 days and can require up to 6 days, even if test results are acceptable on the first try. b. If the test results show the presence of coliform organisms, more time will be required for further disinfection and testing. c. Flushing of the disinfected water main may take considerable time and should be considered in scheduling work. d. The laboratory should be notified at least 24-hours prior to initial disinfection. e. The Contractor shall provide personnel to assist the District lab personnel to obtain samples. B. Repaired Mains, including system interties: The disinfection and bacteriological testing of repaired water mains shall be performed in accordance with the guidelines provided by AWWA C651 and the additions that are written below. 1. All repairs performed by the Contractor, shall be coordinated with the Engineer 2. New pipe segments and fitting shall be swabbed with sodium hypochlorite, as well as the exposed ends of the repaired section. 3. Schedule lab to take tests within 24 hours. Continue until two (2) consecutive negative samples are collected. Corrective action by the contractor may be required and could include flushing, charging, slug chlorination and/or additional repairs at the direction of the Engineer.

Foreword This foreword is for information only and is not a part ofANSt/AWWA C651. I. Introduction. I.A. Background. This standard describes methods of disinfecting newly constructed potable water mains; mains that have been removed from service for planned repairs or for maintenance that exposes them to contamination; mains that have undergone emergency repairs because of physical failure; and mains that, under normal operation,continue to show the presence of coliform organisms.The disinfecting agents discussed in this standard are chlorine solutions that may be derived from liquid chlorine (C12), calcium hypochlorite (Ca(OC1)2), or sodium hypochlorite (NaOC1). Combinations of free chlorine residual and contact time are provided. Chlorine dosage reference tables are provided as appendix B of this standard. I.B. History. This standard was first approved on Sept. 30, 1947, by the AWWA Board of Directors and published as 7D.2-1948,A Procedure for Disinfecting Water Mains. Revisions were approved on Sept. 14, 1948; Mar. 6, 1953; May 27, 1954; June 2, 1968; and June 7, 1981. All were done under the designation ANSI/ AWWA C601, Standard for Disinfecting Water Mains. In 1986, the designation of the standard was changed to ANSI/AWWA C651, and the subsequent editions were approved on Jan. 26, 1986; June 18, 1992; June 20, 1999; and Jan. 16, 2005. This edition was approved on June 8, 2014. I.C. Acceptance. In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium led by NSF International (NSF) to develop voluntary third-party consensus standards and a certification program for direct and indirect drinking water additives.Other members of the original consortium included the Water Research Foundation (formerly AwwaRF) and the Conference of State Health and Environmental Managers (COSHEM). The American Water Works Association (AWWA) and the Association of State Drinking Water Administrators (ASDWA) joined later. In the United States, authority to regulate products for use in, or in contact with, drinking water rests with individual states.t Local agencies may choose to impose requirements more stringent than those required by the state. To evaluate the health *American National Standards Institute,25 West 43rd Street, Fourth Floor,New York,NY 10036. t Persons outside the United States should contact the appropriate authority having jurisdiction.

An advisory program formerly administered by USEPA, Office of Drinking Water, discontinued on Apr. 7, 1990. 2. Specific policies of the state or local agency. 3. Two standards developed under the direction of NSF*: NSF/ANSI 60, Drinking Water Treatment Chemicals—Health Effects, and NSF/ANSI 61, Drinking Water System Components—Health Effects. 4. Other references, including AWWA standards, Food Chemicals Codex, Water Chemicals Codex,t and other standards considered appropriate by the state or local agency. Various certification organizations may be involved in certifying products in accor- dance with NSF/ANSI 60. Individual states or local agencies have authority to accept or accredit certification organizations within their jurisdictions.Accreditation of certi- fication organizations may vary from jurisdiction to jurisdiction. Annex A, "Toxicology Review and Evaluation Procedures," to NSF/ANSI 60 does not stipulate a maximum allowable level (MAL) of a contaminant for substances not regulated by a USEPA final maximum contaminant level (MCL). The MALs of an unspecified list of"unregulated contaminants" are based on toxicity testing guidelines (noncarcinogens) and risk characterization methodology (carcinogens). Use of Annex A procedures may not always be identical, depending on the certifier. ANSI/AWWA C651 does not address additives requirements. Thus, users of this standard should consult the appropriate state or local agency having jurisdiction in order to 1. Determine additives requirements including applicable standards. 2. Determine the status of certifications by parties offering to certify products for contact with, or treatment of, drinking water. 3. Determine current information on product certification. II. Special Issues. II.A. Information on Application of This Standard. Generally, it is easier to disinfect a new main than one that has had emergency repairs in terms of access, sanitary control, and the time available for disinfection, sampling, and testing. *NSF International,789 North Dixboro Road,Ann Arbor,MI 48105. f Both publications available from National Academy of Sciences,500 Fifth Street,NW,Washington, DC 20001. VIII Copyright©2015 American Water Works Association.All Rights Reserved. For a new main, there is typically more time available for disinfection and test- ing since there is no immediate demand from customers. Given the often significant amount of time and materials involved in a new water main project, careful disin- fection and testing of the main are reasonable and necessary to ensure public health protection. Conditions for pipe repair projects vary tremendously in terms of the size of the repair, the sanitary conditions, and the time constraints resulting from immediate cus- tomer demands. It should be noted if the line is depressurized or opened to the envi- ronment prior to or during repair, the sanitary integrity of the pipe is compromised and it is critical to follow sanitary procedures throughout the repair—not just as it is being returned to service. Crews responsible for the repair of mains should be aware of the potential health hazards and be trained to carefully observe prescribed construction practices and disinfection procedures. Because of the differences between initial installation and repair, the disinfec- tion requirements for each situation are also different. The installation of new mains requires that two sets of samples for coliform analysis are collected at least 16 hr apart, or two sets collected 15 min apart after at least a 16-hr rest period. For repaired mains that are depressurized and/or wholly or partially dewatered, one set of samples may be required,and depending on the sanitary conditions, the line may be returned to service prior to the completion of bacteriological testing. For repaired mains that are main- tained under pressurized conditions at all times, bacteriological testing is not required When required, samples are now specified to be collected at least 16 hr apart, or 15 min apart after a 16-hr rest period. The purpose of this change is to consider the balance between public health, improved test methods, and timely work completion. This timing is sufficient to allow bacterial regrowth within the line if there was a con- tamination problem and provides more flexibility in the scheduling of various work activities. Bacteriological testing in accordance with Sec. 5.1 is used to verify the absence of coli- form organisms and is generally accepted as verification that disinfection of the pipeline has been accomplished; and following sanitary practices for handling and installation of pipe, valves, fittings, and accessories, coupled with adequate flushing of the line before disinfection, is necessary to ensure the disinfected pipeline will be ready for connection to the water system. Failure to pass the bacteriological test requires that the flushing or disinfection process be repeated. It must be remembered that the final water quality test is not the primary means for certifying the sanitary condition of a main. The sanitary ix Copyright©2015 American Water Works Association.All Rights Reserved. handling of materials, the practices during construction, and the continual inspection of the work are the primary means for ensuring the sanitary condition of the water main. Four methods of disinfecting newly constructed water mains are described in this standard: the tablet method, the continuous-feed method, the slug method, and the spray method. The utility should decide which of these methods is most suitable for a given situation. Factors to consider when choosing a method should include the length and diameter of the main, type of joints present, availability of materials, equipment required for disinfection, training of the personnel who will perform the disinfection, and safety concerns. For example, if gas chlorination is the chosen chemical when either continuous-feed or slug methods are being used, use only properly designed and constructed equipment; makeshift equipment is not acceptable when liquid chlorine (gas) cylinders are used. Thorough consideration should be given to the impact of highly chlorinated water flushed into the environment. If there is any question that damage may be caused by chlorinated-waste discharge (to fish life, plant life, physical installations, or other downstream water uses of any type),then an adequate amount of reducing agent should be applied to water being disposed of in order to thoroughly neutralize the chlorine residual remaining in the water. The tablet method cannot be used unless the main can be kept clean and dry. It cannot be used in large-diameter mains if it is necessary for a worker to enter the main to grout joints or perform inspection because the tablets may release toxic fumes after exposure to moist air.When using the tablet method, the chlorine concentration is not uniform throughout the main because the hypochlorite solution is dense and tends to concentrate at the bottom of the pipe. The use of the tablet method precludes prelimi- nary flushing. The tablet method is convenient to use in mains having diameters up to 24 in. (600 mm), and it requires no special equipment. The continuous-feed method is suitable for general application. Preliminary flush- ing removes light particulates from the main but not from the pipe-joint spaces. The chlorine concentration is uniform throughout the main. The slug method is suitable for use in large-diameter mains where the volume of water makes the continuous-feed method impractical and difficult to achieve for short attachments. The slug method results in appreciable savings of chemicals used to disinfect long large-diameter mains. Also, this method reduces the volume of heavily chlorinated water to be flushed to waste. x Copyright©2015 American Water Works Association.All Rights Reserved. The spray method is suitable for use in large-diameter transmission lines where spray equipment can be used to disinfect all surfaces of the pipe. This method reduces the volume of heavily chlorinated water to be flushed to waste. The purpose of all four chlorination methods is to disinfect water lines, resulting in an absence of coliforms as confirmed by laboratory analysis. As noted above, the four methods attempt to provide flexibility in responding to specific situations. The tablet and continuous-feed methods both have initial chlorine concentrations of 25 mg/L and a minimum contact time of 24 hr. Because the tablet method cannot be flushed and cleaned prior to disinfection, the required free chlorine residual must be detectable (>_0.2 mg/L) after 24 hr. Because the continuous-feed method can be used to flush particles, a higher free chlorine residual of 10 mg/L is required after 24 hr. To meet the needs of situations requiring reduced contact times, the slug method allows only a 3-hr contact time but requires a 100-mg/L initial chlorine dosage. For larger transmis- sion lines, spray disinfection using 200 mg/L free chlorine may be a suitable option, minimizing discharges of highly chlorinated water. While the contact times of the methods may not be identical, the end result, absence of coliforms, is the same for all four methods. Disinfectants other than chlorine may be appropriate to use. Although this stan- dard describes only the use of liquid chlorine (gas), sodium hypochlorite solutions, and calcium hypochlorite, the applicability of other disinfectants should be evaluated. Ozone and chemical cleaners have been used, and these warrant further investiga- tion. Whichever disinfectant or method is selected, approval from the local regulatory agency may be required. III.

SECTION 4: REQUIREMENTS Materials shall comply with the requirements of the Safe Drinking Water Act and other federal regulations for potable water, wastewater, and reclaimed water systems as applicable. Sec. 4.1 Forms of Chlorine for Disinfection The forms of chlorine that may be used in the water main disinfection opera- tions are liquid chlorine (gas), sodium hypochlorite solution, and calcium hypo- chlorite granules or tablets. 4.1.1 Liquid chlorine (gas). Liquid chlorine (gas) conforming to ANSI/ AWWA B301 contains 100 percent available chlorine and is packaged in steel containers usually of 100-lb, 150-1b, or 1-ton (45.4-kg, 68.0-kg, or 907.2-kg) net chlorine weight. Liquid chlorine (gas) shall be used only (1) in combination with appropriate gas-flow chlorinators and ejectors to provide a controlled high-concen- tration solution feed to the water to be chlorinated; (2) under the direct supervision of someone familiar with the biological,chemical,and physical properties of liquid chlorine (gas) and who is trained and equipped to handle any emergency that may arise; and (3) when appropriate safety practices are observed to protect working personnel and the public.Makeshift equipment is not acceptable when liquid chlo- rine (gas) cylinders are used. Copyright©2015 American Water Works Association.All Rights Reserved. 4 AWWA C651-14 4.1.2 Sodium hypochlorite. Sodium hypochlorite conforming to ANSI/ AWWA B300 is available in liquid form in glass, rubber-lined, or plastic contain- ers typically ranging in size from 1 qt (0.95 L) to 5 gal (18.92 L). Containers of 30 gal (113.6 L) or larger may be available in some areas. Sodium hypochlorite contains approximately 5 percent to 15 percent available chlorine, and the storage conditions and time must be controlled to minimize its deterioration. (Available chlorine is expressed as a percent of weight when the concentration is 5 percent or less, and usually as a percent of volume for higher concentrations. Percent x 10 = grams of available chlorine per liter of hypochlorite.) 4.1.3 Calcium hypochlorite. Calcium hypochlorite conforming to ANSI/ AWWA B300 is available in granular form or in 5-g tablets and must contain approximately 65 percent available chlorine by weight. The material should be stored in a cool, dry, and dark environment to minimize its deterioration. CAUTION:Tablets dissolve in approximately 7 hr and must be given adequate contact time. Do not use calcium hypochlorite intended for swimming pool disin- fection, as this material has been sequestered and is extremely difficult to eliminate from the pipe after the desired contact time has been achieved. Sec. 4.2 General Considerations for All Methods of Chlorination 4.2.1 General. Four methods of chlorination are explained in this sec- tion: tablet, continuous feed, slug, and spray. The tablet method gives an initial chlorine dose of 25 mg/L; the continuous-feed method gives a 24-hr chlorine residual of not less than 10 mg/L; the slug method gives a 3-hr exposure of not less than 50 mg/L free chlorine; and the spray method gives a 30-min exposure of not less than 200 mg/L free chlorine. Caution should be used with highly chlorinated water when conducting hydrostatic pressure testing and with high- volume flushing of water. 4.2.2 Flushing. Potable water shall be used for disinfection, hydrostatic pressure testing, and flushing. Drainage should take place away from the construc- tion or work area. Adequate drainage must be provided during flushing. If appli- cable, the valve(s) isolating the main from existing system should be locked out and tagged out to prevent unintentional release of the elevated chlorine residual water used for disinfection. 4.2.3 Dechlorination. When dechlorination is required, it is recom- mended that any high-velocity flushing be completed prior to disinfection. Dechlo- rination equipment may not be capable of handling high flows with high levels of chlorine. Copyright©2015 American Water Works Association.All Rights Reserved.

The tablet method consists of placing calcium hypo- chlorite granules or tablets in the water main during installation and then filling the main with potable water to create a chlorine solution.This method may be used only if the pipes and appurtenances are kept clean and dry during construction. WARNING: This procedure must not be used on solvent-welded plastic or on screwed-joint steel pipe because of the danger of fire or explosion from the reaction of the joint compounds with the calcium hypochlorite. 4.3.2 Placement of calcium hypochlorite granules during construction. Cal- cium hypochlorite granules shall be placed at the upstream end of the first section of pipe, at the upstream end of each branch main, and at 500-ft (150-m) intervals. The quantity of granules at each location shall be as shown in Table 1. 4.3.3 Placement of calcium hypochlorite tablets during construction. Cal- cium hypochlorite tablets (5-grams) shall be placed in the upstream end of each section of pipe to be disinfected, including branch lines. Also, at least one tablet shall be placed in each hydrant branch and in other appurtenances.The number of 5-g tablets required for each pipe section shall be 0.0012 d2L rounded to the next higher integer, where d is the inside pipe diameter, in inches, and L is the length of the pipe section,in feet.Table 2 shows the number of tablets required for commonly used sizes of pipe. Calcium hypochlorite tablets shall be attached by an adhesive meeting the requirements of NSF/ANSI 61. There shall be adhesive only on the broadside of the tablet attached to the surface of the pipe.

When installation has been completed, the main shall be filled with water such that the full pipe velocity is no greater than 1 ft/sec (0.3 m/sec). Fill rate must be carefully controlled to ensure tablets do not come loose from pipe. Precautions shall be taken to ensure that air pockets are eliminated. As an optional procedure, if required by the purchaser, water used to fill the new main shall be supplied through a temporary connection that shall include an appropriate cross-connection control device, consistent with the degree of hazard, for backflow protection of the active distribution system (see Figure 1). The chlorinated water shall remain in the pipe for at least 24 hr. If the water temperature is less than 41°F (5°C), the water shall remain in the pipe for at least 48 hr. A detectable free chlorine residual 0.2 mg/L) shall be found at each sampling point after the 24- or 48-hr period. Sec. 4.4 Continuous-Feed Method of Chlorination 4.4.1 Continuous feed method. The continuous-feed method consists of completely filling the main with potable water, removing air pockets, then flush- ing the completed main to remove particulates,and refilling the main with potable water that has been chlorinated to 25 mg/L. After a 24-hr holding period in the main there shall be a free chlorine residual of not less than 10 mg/L. 4.4.2 Preliminary flushing. Before the main is chlorinated,it shall be filled with potable water to eliminate air pockets and flushed to remove particulates. The flushing velocity in the main shall not be less than 3.0 ft/sec (0.91 m/sec) unless Copyright©2015 American Water Works Association.All Rights Reserved.

Table 3 shows the rates of flow required to produce a velocity of 3.0 ft/sec (0.91 m/sec) in commonly used sizes of pipe. (NOTE: flushing is no sub- stitute for preventive measures during construction. Certain contaminants,such as caked deposits, resist flushing at any feasible velocity, and pigging of the main, or other suitable method acceptable to the purchaser, may be required.) Where such flow rates are not possible, flushing at the maximum expected flow rate for the line for 2-3 volumes may be acceptable. For larger mains, pigging (or other suitable method acceptable to the purchaser) is an option in place of high velocity flushing. For 24-in. (600-mm) or larger diameter mains, an acceptable alternative to flushing is to broom-sweep the main, carefully removing sweepings prior to filling and chlorinating the main. WARNING: OSHA requirements for confined space need to be addressed before entering a pipeline. 4.4.3 Procedure for chlorinating the main. 1. Potable water may be supplied from a temporary backflow-protected con- nection to the existing distribution system or other supply source approved by the purchaser. The cross-connection control device shall be consistent with the degree of hazard for backflow protection of the active distribution system (see Figure 1). The flow shall be at a constant, measured rate into the newly installed water main. In the absence of a meter, the rate may be approximated using a Pitot gauge in the discharge, measuring the time to fill a container of known volume, or measuring the trajectory of the discharge and using the formula shown in Figure 2. The main should undergo hydrostatic testing prior to disinfection. 2. At a point not more than 10 ft (3 m) downstream from the beginning of the new main,water entering the new main shall receive a dose of chlorine fed at a constant rate such that the water will have not less than 25 mg/L free chlorine. To ensure that an appropriate concentration is achieved, the free chlorine concentra- tion shall be measured at regular time intervals in accordance with the procedures described in Standard Methods for the Examination of Water and Wastewater or AWWA Manual M12, or using appropriate chlorine test kit (see appendix A). Table 4 gives the amount of chlorine required for each 100 ft (30.5 m)of pipe for various pipe diameters. Solutions with a minimum 1 percent chlorine concen- tration may be prepared with sodium hypochlorite or calcium hypochlorite. The latter solution requires 1 lb (454 g) of calcium hypochlorite in 8 gal (30.3 L) of water. Copyright©2015 American Water Works Association.All Rights Reserved.

Chlorine application shall not cease until the entire main is filled with chlorinated water. The chlorinated water shall be retained in the main for at least 24 hr, during which time valves and hydrants in the treated section shall be oper- ated to ensure disinfection of the appurtenances. At the end of this 24-hr period, the treated water in all portions of the main shall have a residual of not less than 10 mg/L of free chlorine. 4. Direct-feed chlorinators,which operate solely from gas pressure in a chlo- rine cylinder, shall not be used for the application of liquid chlorine (gas). (The Copyright©2015 American Water Works Association.All Rights Reserved. 10 AWWA C651-14 danger of using direct-feed chlorinators is that water pressure in the main can exceed gas pressure in the chlorine cylinder. This allows backflow of water into the cylinder, resulting in severe cylinder corrosion and the escape of chlorine gas.) The preferred equipment for applying liquid chlorine (gas) is a solution-feed, vacuum-operated chlorinator and a booster pump. The vacuum-operated chlori- nator mixes the chlorine gas in solution water; the booster pump then injects the chlorine solution into the main to be disinfected. Hypochlorite solutions may be applied to the water main with a chemical-feed pump designed for feeding chlorine solutions. Feed lines shall be made of material capable of withstanding the corro- sion caused by the concentrated chlorine solutions and the maximum pressures that may be created by the pumps. All connections shall be checked for tightness before the solution is applied to the main. Sec. 4.5 Slug Method of Chlorination 4.5.1 Slug method. The slug method consists of completely filling the main to eliminate air pockets; flushing the main to remove particulates; then slowly flowing through the main a slug of water dosed with chlorine to a concen- tration of 100 mg/L. The slow rate of flow ensures that all parts of the main and its appurtenances will be exposed to the highly chlorinated water for a period of not less than 3 hr. 4.5.2 Preliminary flushing. Same as Sec. 4.4.2. 4.5.3 Procedure for chlorinating the main. 1. Potable water may be supplied from a temporary backflow-protected con- nection to the existing distribution system or other supply source approved by the purchaser. The cross-connection control device shall be consistent with the degree of hazard for backflow protection of the active distribution system (see Figure 1). The flow shall be at a constant, measured rate into the newly installed water main. In the absence of a meter, the rate may be approximated using a Pitot gauge in the discharge, measuring the time to fill a container of known volume, or measuring the trajectory of the discharge and using the formula shown in Figure 2. The main should undergo hydrostatic testing prior to disinfection. 2. At a point not more than 10 ft (3 m) downstream from the beginning of the new main, water entering the new main shall receive a dose of chlorine fed at a constant rate such that the water will have not less than 100 mg/L free chlorine. To ensure that this concentration is achieved, the free chlorine concentration shall be measured at regular time intervals sufficient to guide the completion of the suc- cessful loading of the target chlorine concentration. The chlorine shall be applied Copyright©2015 American Water Works Association.All Rights Reserved. DISINFECTING WATER MAINS 11 continuously and for a sufficient period to develop a solid column, or slug, of chlo- rinated water that will,as it moves through the main,expose all interior surfaces to a concentration of approximately 100 mg/L for at least 3 hr. 3. The free chlorine residual shall be measured in the slug as it moves through the main. If at any time it drops below 50 mg/L, the flow shall be stopped; chlorination equipment shall be relocated at the head of the slug; and, as flow resumes, chlorine shall be applied to restore the free chlorine in the slug to not less than 100 mg/L. 4. As chlorinated water flows past fittings and valves, related valves and hydrants shall be operated so as to disinfect appurtenances and pipe branches. Sec. 4.6 Spray Disinfection for Large Transmission Lines For very large transmission mains (where personnel or equipment may safely enter the pipe), spray disinfection may be an appropriate and efficient means of achieving disinfection. For this method, refer to ANSI/AWWA C652, Sec. 4.3.2 (Disinfection of Water Storage Facilities; Chlorination Method 2). In general, once pipe is cleaned, spray a 200-mg/L free chlorine solution on all surfaces. After 30 min, fill line and sample as described in Sec. 5.1. Sec. 4.7 Basic Disinfection Procedure for New Mains The basic disinfection procedure consists of 1. Inspecting materials to be used to ensure their integrity. 2. Preventing contaminating materials from entering the water main during storage, construction, or repair and noting potential contamination at the con- struction site. 3. Removing, by flushing or other means, those materials that may have entered the water main or appurtenances. 4. Preventing contamination of existing mains from cross-connection dur- ing flushing, pressure testing, and disinfection. 5. Pressure testing the water main to ensure the main meets the purchaser's allowable leakage rate. Hydrostatic pressure tests should be conducted with potable water. 6. Chlorinating and adequately documenting the process used for disin- fection. 7. Flushing the chlorinated water from the main. Refer to ANSI/AWWA C655 Field Dechlorination for dechlorination procedures, if dechlorination is required. Copyright©2015 American Water Works Association.All Rights Reserved. 12 AW WA C651-14 8. Determining the bacteriological quality of water samples collected from the pipe by laboratory test after disinfection. 9. Final connecting of the newly disinfected water main to the active distri- bution system without sacrificing sanitary practices and conditions. Sec. 4.8 Preventive and Corrective Measures During New Construction 4.8.1 General. Heavy particulates generally contain bacteria and prevent even very high chlorine concentrations from contacting and killing these organisms. Therefore, the procedures of this section must be observed to ensure that a water main and its appurtenances have been thoroughly cleaned for the final disinfection by chlorination. Also, any connection of a new water main to the active distribu- tion system before the receipt of satisfactory bacteriological samples may constitute a cross-connection.Therefore,the new main must be isolated until bacteriological tests described in Section 5 of this standard are satisfactorily completed. 4.8.2 Keeping pipe dean and dry. The interiors of pipes, fittings, and valves shall be protected from contamination. 4.8.2.1 Openings. Openings in the pipeline shall be closed with water- tight plugs when pipe laying is stopped at the close of the day's work or for other reasons,such as rest breaks or meal periods. Rodent-proof plugs may be used when watertight plugs are not practicable and when thorough cleaning will be performed by flushing or other means. 4.8.2.2 Stringing pipe. Pipe delivered for construction shall be strung to minimize the entrance of foreign material. 4.8.2.3 Delays. Delay in placement of delivered pipe invites contamina- tion. The more closely the rate of delivery is correlated to the rate of pipe laying, the lower the risk of contamination. 4.8.3 Joints. Joints of pipe in the trench shall be completed before work is stopped. If water accumulates in the trench, the plugs shall remain in place until the trench is free of standing water and mud that may enter the pipe. 4.8.4 Packing materials. Yarning or packing material shall consist of molded or tubular rubber rings, rope of treated paper, or other approved materials. Materials such as jute or hemp shall not be used. Packing material shall be handled in a manner that avoids contamination. 4.8.5 Sealing materials. No contaminated material or any material capa- ble of supporting growth of microorganisms shall be used for sealing joints. Seal- ing material or gaskets shall be handled in a manner that avoids contamination. The lubricant used in the installation of sealing gaskets shall be suitable for use in Copyright©2015 American Water Works Association.All Rights Reserved. DISINFECTING WATER MAINS 13 potable water meeting the requirements of NSF/ANSI 61 and shall not contribute odors. It shall be delivered to the job in closed containers and shall be kept clean and applied with dedicated clean applicators. 4.8.6 Cleaning and swabbing. If dirt enters the pipe, it shall be removed and the interior pipe surface swabbed with a minimum 1 percent free chlorine disinfecting solution. If, in the opinion of the purchaser, the dirt remaining in the pipe will not be removed using the flushing operation, the interior of the pipe shall be cleaned using mechanical means,such as a hydraulically propelled foam pig (or other suitable device acceptable to the purchaser) in conjunction with the appli- cation of a minimum 1 percent free chlorine disinfecting solution. The cleaning method used shall not force mud or debris into the interior pipe-joint spaces and shall be acceptable to the purchaser. 4.8.7 Wet-trench construction. If it is not possible to keep the pipe and fit- tings dry during installation, a scour flush at 3.0 ft/sec (0.91 m/sec) or greater for a minimum of three pipe volumes (see Table 3) followed by slug or continuous-feed chlorination and bacteria testing before release is required. For larger mains, pig- ging or other suitable method acceptable to the purchaser is an option in place of high-velocity flushing. 4.8.8 Flooding by storm or accident during construction. If the main is flooded during construction, it shall be cleared of the floodwater by draining and flushing with potable water until the main is clean. The section exposed to the floodwater shall then be filled with a chlorinated potable water that, at the end of a 24-hr holding period, will have a free chlorine residual of not less than 25 mg/L. The chlorinated water may then be drained or flushed from the main. If chemical contamination occurs, such as a hydraulic oil leak or petroleum product spill, the pipe sections exposed to the contamination should be replaced and not reused for potable water applications.After construction is completed, the main shall be dis- infected using the continuous-feed, slug, or spray methods. 4.8.9 Backflow protection(optional).* As an optional procedure(if required by the purchaser), the new water main shall be kept isolated from the active distri- bution system using a physical separation (see Figure 1) until satisfactory bacterio- logical testing has been completed and the disinfection water flushed out. Water required to fill the new main for hydrostatic pressure testing, disinfec- tion, and flushing shall be supplied through a temporary connection between the *Optional Sec.4.8.9 is not included as part of the standard unless required by the purchaser. Copyright©2015 American Water Works Association.All Rights Reserved. 14 AWWA C651-14 distribution system and the new main or other supply source approved by the pur- chaser. The temporary connection shall include an appropriate cross-connection control device consistent with the degree of hazard (a double check valve assembly or a reduced pressure zone assembly) and shall be disconnected (physically sepa- rated) from the new main during the hydrostatic pressure test. It will be necessary to reestablish the temporary connection after completion of the hydrostatic pres- sure test to flush out the disinfectant water prior to final connection of the new main to the distribution system. NOTE: Exposure to high levels of chlorine or high pH can cause severe irritation to customers. Also, the chlorinated water can be high in disinfection by-products. Sec. 4.9 Final Flushing for New Mains 4.9.1 Clearing the main of heavily chlorinated water. After the applicable retention period,heavily chlorinated water should not remain in prolonged contact with pipe. In order to prevent damage to the pipe lining or to prevent corrosion damage to the pipe itself, the heavily chlorinated water shall be flushed from the main fittings,valves,and branches until chlorine measurements show that the con- centration in the water leaving the main is no higher than that generally prevailing in the distribution system or that is acceptable for domestic use. 4.9.2 Disposing of heavily chlorinated water. The environment to which the chlorinated water is to be discharged shall be inspected. If there is any possibil- ity that the chlorinated discharge will cause damage to the environment, a neutral- izing chemical shall be applied to the water to be wasted to thoroughly neutralize the residual chlorine (see ANSI/AWWA C655 for neutralizing chemicals). Where necessary, federal, state, local, or provincial regulatory agencies should be con- tacted to determine special provisions for the disposal of heavily chlorinated water. Sec. 4.10 Final Connections to Existing Mains Water mains and appurtenances must be completely installed, flushed, disin- fected, and satisfactory bacteriological sample results received prior to permanent connections being made to the active distribution system. Sanitary construction practices must be followed during installation of the final connection so that there is no contamination of the new or existing water main with foreign material or groundwater. 4.10.1 Connections equal to or less than one pipe length (generally _<20 ft [6 ml). The new pipe, fittings, and valve(s) required for the connection may be spray disinfected or swabbed with a minimum 1 percent solution of chlorine just Copyright©2015 American Water Works Association.All Rights Reserved. DISINFECTING WATER MAINS 15 before being installed, if the total length of the connection from the end of a new main to the existing main is equal to or less than 20 ft (6 m). 4.10.2 Connections greater than one pipe length (generally >20 ft[6 m]). The pipe required for the connection must be set up aboveground,disinfected,and bacte- riological samples taken, as described in Section 5, if the total length of the connec- tion from the end of a new main to the existing main is greater than 20 ft(6 m).After satisfactory bacteriological sample results have been received for the predisinfected pipe, the pipe can be used in connecting the new main to the active distribution system. Between the time the satisfactory bacteriological sample results are received and the time that the connection piping is installed, the ends of the piping must be sealed with plastic wraps,watertight plugs, or caps. Sec. 4.11 Disinfection Procedures When Cutting Into or Repairing Existing Pipe 4.11.1 General. The planned, unplanned, or emergency repair of a water main or appurtenance(e.g., valve) is time sensitive—an important goal is to mini- mize the disruption of water service to customers. Nonetheless, the repair work needs to be accomplished using sanitary and safe procedures by well-trained crews with proper supervision and guidance. Refer to preventive and corrective measures described previously in Sec. 4.8.2,4.8.3, 4.8.4, and 4.8.5. Follow all personal pro- tection precautions when working with chlorine solutions. 4.11.2 Basic disinfection. Work should follow basic disinfection and con- tamination prevention procedures: 1. Preventing contaminants from entering the existing pipe during the repair such as by maintaining positive pressure in the leaking pipe until the repair site on the pipe is fully exposed, by maintaining a dewatered trench, and by keeping all pipe materials being used in the repair in a clean and sanitary condition. 2. Inspecting and cleaning, followed by disinfection of spraying or swabbing with a minimum 1 percent chlorine solution: • Exposed portions of existing pipe interior surfaces • Pipe materials used in the repair • Handheld materials and tools used to make the repair 3. As appropriate, advising affected customers to adequately flush their ser- vice lines upon return to service. 4.11.3 Selection of disinfection procedure. The disinfection procedure selected should be determined by the conditions and severity of the main break. Many leaks or breaks can be repaired under controlled conditions without depres- surizing the water main, such as when applying a clamp to a small crack or hole, Copyright©2015 American Water Works Association.All Rights Reserved. 16 AWWA C651-14 thus preventing contaminants from entering the water system. In most other situa- tions, the water main can be maintained pressurized until the break site is secured and the pipe is fully exposed. Some circumstances (e.g., severe erosion of the local environment or icing of the roadway) that impact public safety may require that water pressure be substantially reduced prior to exposing the pipe in the area of the leak. In some cases, situations become catastrophic where there is a pipe blow- out and a loss of water pressure prior to shutdown, requiring disinfection proce- dures equivalent to those of a new main installation. The procedures described in Sec. 4.11.3.1 through 4.11.3.3 describe the contamination risks and the associated disinfection and sampling requirements for different scenarios of pipeline repair. Specific situations not captured below need to be evaluated and the appropriate disinfection and sampling methods followed. Note that the procedures explained in Sec. 4.11.3.1, 4.11.3.2,and 4.11.3.3 for distribution mains may need to be modified for large transmission mains. Large mains may need additional work (such as having a valve replaced or requiring a special order on a connection), may be out of service for more than a day, or may not be able to accommodate a scour flush. These modifications need to be made on a case-by-case basis but should still take into account the procedures outlined in ANSI/AWWA C651. 4.11.3.1 Controlled pipe repair without depressurization. In this situa- tion, activities are well controlled and a full shutdown is not needed, thus main- taining positive pressure to the area of shutdown and around the break site at all times. The repair site is exposed and the trench is adequately dewatered so that the repair site can be cleaned and disinfected by spraying or swabbing with a mini- mum 1 percent chlorine solution. The water main is then returned to service with flushing to obtain three volumes of water turnover, making sure that the flushed water is visually clear. No bacteriological testing is necessary. It is advisable to check for a typical system chlorine residual, and if not found, to continue flushing until residuals are restored to levels maintained in the distribution system by the water utility—if the system operates with a disinfectant residual. 4.11.3.2 Controlled pipe repair with depressurization after shutdown. In this situation, after the repair site has been exposed and secured from trench soil/ water contamination, the water main is depressurized by a shutdown to complete the repair. The repair site should be cleaned and disinfected by spraying or swab- bing with a minimum 1 percent chlorine solution.The water main is then returned to service with flushing to scour the pipe and obtain three volumes of water turn- Copyright©2015 American Water Works Association.All Rights Reserved. DISINFECTING WATER MAINS 17 over, making sure that the flushed water is visually clear. It is advisable to check for a typical system chlorine residual, and if not found, to continue flushing until residuals are restored to levels maintained in the distribution system by the water utility—if the system operates with a disinfectant residual. When the existing pipe has to be opened and the interior surfaces of the water system exposed to the environment, additional procedures need to be followed. The existing pipe should be inspected and cleaned with the help of flushing water into the trench, where possible, until the flush water runs visually clear. The repair site should be accessible and the trench adequately dewatered so that the repair site can be cleaned and disinfected by spraying or swabbing with a minimum 1 percent chlorine solution.Additionally, any accessible upstream and downstream interior of the exist- ing pipe should be disinfected by swabbing or spraying with a minimum 1 percent chlorine solution. If the repair requires a full pipe section replacement, the new pipe should be inspected, cleaned, and disinfected from both ends by swabbing with a minimum 1 percent chlorine solution. The water main may then be returned to service after flushing to scour the pipe and obtain three volumes of water turnover. The flushed water should run visually clear, have a measurable chlorine residual if the system operates with a residual, and be checked with bacteriological testing. The pipeline may be returned to service prior to obtaining bacteriological results. 4.11.3.3 Uncontrolled pipe break with a likelihood of water contamination or loss of sanitary conditions during repair. In situations in which the existing main to be repaired could not be protected and kept free of contamination and there are obvious signs of contamination (e.g., muddy trench water flowing into the broken pipe and a leaking sewer pipe in the trench, or catastrophic pipe failure where pipe is open and there is a likelihood that contamination was drawn into the active system) or when a controlled repair situation turns into a situation in which the internal pipe and water have become contaminated, the procedures outlined in Sec. 4.3, 4.4, 4.5, or 4.6 should be followed where practical. These methods specify chlorine doses of 25-300 mg/L; however, such levels may present greater harm if the line or services cannot be reliably isolated or shut down and exposure of customers to high concentrations of chlorine cannot be controlled. Free chlorine residuals up to 4 mg/L (based on annual averages) are allowed by federal drinking water regulations; therefore this level is suggested as a minimum to be maintained for at least 16 hr in conjunction with flushing, coliform sampling, and associated customer education. Such situations require careful review and need to balance the public health risks of the pipeline failure as well as the repair process. Copyright©2015 American Water Works Association.All Rights Reserved. 18 AWWA C651-14 Where practical and appropriate considering the risks of public exposure to high concentrations of chlorine, in addition to the procedures previously described in this standard, the section of pipe in which the break is located shall be isolated, all service connections shut off, and the section flushed and disin- fected. If the slug chlorination method is employed, the dose may be increased to as much as 300 mg/L and the contact time reduced to as little as 15 min. After chlorination and repair, perform scour flushing at 3.0 ft/sec (0.91 m/sec) or greater for a minimum of three pipe volumes and continue until discolored water is not observed and the chlorine residual is restored to the levels maintained in the distribution system by the water utility. For larger-diameter pipe (12 in. and greater), if a water velocity of 3.0 ft/sec (0.91 m/sec) cannot be achieved, it is desirable to flush at the maximum flow for the main until three pipe volumes have been displaced before returning the main to service. The flushed water should run visually clear, and have typical system chlorine residual (if the system operates with a disinfectant residual). For very-large-diameter pipe (where personnel may safely enter the pipe), in lieu of flushing following disinfection, the interior of the pipe at the repair site may be cleaned by sweeping or high pressure wash using potable water before disinfec- tion. Standing water and debris from the cleaning must be removed from the pipe prior to disinfection.The affected pipe shall be disinfected by swabbing or spraying with a minimum 1 percent chlorine solution. After following the appropriate methods above, prior to returning the pipe to service, the efficacy of the disinfection procedure shall be verified by testing for the absence of coliform bacteria. If allowed by local regulations, the pipeline may be returned to limited service prior to obtaining bacteriological results with proper notification of the affected customers. 4.11.4 Temporary service lines. Temporary water service lines to custom- ers during main repair activities shall be disinfected prior to use. Materials shall meet the NSF/ANSI 61 certification for potable water use. Disinfection should be accomplished by the procedures in Sec. 4.4 or 4.5 followed by scour flushing at 3.0 ft/sec (0.91 m/sec) or greater for a minimum of three pipe volumes (see Table 3), or until the water runs visually clear and preferably a measurable chlo- rine residual is restored.

It should be recognized that the primary means of ensuring the sanitary integrity of a main are the sanitary han- dling of materials, the practices during construction, and continual inspection of work.After disinfection and final flushing such that typical system chlorine residu- als are present, if the system operates with a residual, samples shall be collected as follows: 5.1.1.1 For new mains, the purchaser has two options for the bacteriologi- cal testing for total coliform analysis. Option A: Before approving a main for release, take an initial set of samples and then resample again after a minimum of 16 hr using the sampling site procedures outlined. Both sets of samples must pass for the main to be approved for release. Option B: Before approving a main for release, let it sit for a minimum of 16 hr without any water use. Then collect, using the sampling site procedures outlined and without flushing the main, two sets of samples a minimum of 15 min apart while the sampling taps are left running. Both sets of samples must pass for the main to be approved for release. A set of samples includes all samples collected along the length of the pipeline, as described in Sec. 5.1.1.2. 5.1.1.2 For new mains, sets of samples shall be collected every 1,200 ft (370 m) of the new water main, plus one set from the end of the line and at least one from each branch greater than one pipe length. 5.1.1.3 If trench water has entered the new main during construction or if, in the opinion of the purchaser, excessive quantities of dirt or debris have entered the new main, bacteriological samples shall be taken at intervals of approximately 200 ft (61 m), and the sampling location shall be identified (see Sec. 5.1.3 for sam- pling location details). Samples shall be taken of water that has stood in the new main for at least 16 hr after final flushing has been completed. 5.1.1.4 A standard heterotrophic plate count(HPC) test may be required at the option of the purchaser because new mains do not typically contain coliform bacteria but often contain HPC bacteria. If sample results show HPC greater than 500 CFU/mL, flushing should resume and another set of HPC and coliform sam- ples collected until no coliform are present and the HPC is less than 500 CFU/mL. Copyright©2015 American Water Works Association.All Rights Reserved. 20 AWWA C651-14 5.1.2 Standard conditions for repaired mains. It should be recognized that the primary means of ensuring the sanitary integrity of a main are the sanitary handling of materials, the practices during repair work, and continual inspection of work.After disinfection and final flushing,samples shall be collected as follows: 5.1.2.1 For repaired mains that were depressurized and/or wholly or par- tially dewatered, one set of samples may be required, and depending upon the sanitary conditions, the line may be reactivated prior to the completion of bacte- riological testing. Samples shall be collected downstream of the repair site and at intervals of approximately 200 ft (61 m) within the length of pipe that was shut down. If direction of flow is not known,samples shall be collected on either side of the repair site. Refer to Sec. 4.11. 5.1.2.2 For repaired mains that were maintained under pressurized conditions at all times, disinfection and/or testing may not be required. Refer to Sec. 4.11.3. 5.1.2.3 However, under either main repair scenario, it is advisable where possible to provide a scour flush to clear before the release of the repaired section. 5.1.3 Sampling procedure. Samples for bacteriological analysis shall be col- lected in sterile bottles treated with sodium thiosulfate, in accordance with Section 9060—Samples of Standard Methods fir the Examination of Water and Wastewater. Hoses and fire hydrants are not recommended for the collection of samples that will be used to make decisions on the bacteriological quality of drinking water. How- ever, if no sampling port is available, cleaned fire hydrants that have been cleared of standing water and/or other sanitized sampling apparatus (i.e., sanitized tubing, hose, gooseneck, spigot) may be used with the understanding that they do not rep- resent optimum access to the water main for bacteriological sampling. A suggested combination blowoff and sampling tap used for mains up to and including 8-in. (200-mm) diameter is shown in Figure 2.There should be no water in the trench up to the connection for sampling. The sampling pipe must be dedicated and clean and disinfected and flushed prior to sampling.A corporation cock may be installed in the main with a copper-tube gooseneck assembly.After samples have been collected, the gooseneck assembly may be removed and retained for future use and the corporation cock should be capped or taped for future reuse. If corporation cocks are placed at the 12 o'clock position, they may be struck more easily during future excavations. 5.1.4 Sample results. Samples shall be tested for bacteriological quality in accordance with Standard Methods for the Examination of Water and Wastewater and shall show the absence of coliform bacteria. Copyright©2015 American Water Works Association.All Rights Reserved. DISINFECTING WATER MAINS 21 In addition, it is recommended that samples be tested for acceptable aesthetic quality (e.g., chlorine residual, pH, alkalinity, specific conductance, turbidity). Levels should be as expected or typical for the water system. For new mains,a stan- dard heterotrophic plate count test may be required at the option of the purchaser because new mains do not typically contain coliform bacteria but often contain HPC bacteria. If sample results show HPC greater than 500 CFU/mL, flushing should resume and another set of HPC and coliform samples collected until no coliform are present and the HPC is less than 500 CFU/mL. 5.1.5 Record of compliance. The record of compliance shall be the bacte- riological test results certifying that the water sampled is free of coliform bacteria contamination. 5.1.6 Redisinfection. If the initial disinfection fails to produce satisfac- tory bacteriological results, or if other results indicate unacceptable water quality, the main may be reflushed and shall be resampled. If check samples fail to pro- duce acceptable results, the main shall be rechlorinated by the continuous-feed or slug method until satisfactory results are obtained—that being acceptable samples taken as described in Sec. 5.1.1.1. NOTE: In the case of new mains, high velocities in the adjacent existing sys- tem, resulting from flushing the new main, may disturb sediment that has accu- mulated in the existing mains. When check samples are taken, it is advisable to sample water entering the new main to determine if excessive turbidity is present that could be interfering with results. Sec. 5.2 Optional Sampling and Testing If a pipeline is not promptly returned to service, the situation should be evalu- ated to determine if the water quality may have been impacted and if additional testing is warranted. Test results should confirm that the water quality is appropri- ate for distribution.Although this assessment is unique for each system, parameters considered for testing include disinfectant residual, total coliform bacteria, HPC, turbidity, pH, alkalinity, total chlorine, odor, and specific conductance.

SECTION A.1: DPD DROP DILUTION METHOD (FOR FIELD TEST) The N, N-diethyl-p-phenylenediamine (DPD) drop dilution method of approximating total residual chlorine is suitable for concentrations above 10 mg/L, such as those applied in the disinfection of water mains or tanks. Sec.A.1.1 Apparatus 1. A graduated cylinder for measuring distilled water. 2. An automatic or safety pipette. 3. Two dropping pipettes that deliver a 1-mL sample in 20 drops. One pipette is for dispensing the water sample, and the other is for dispensing the DPD and buffer solutions. The pipettes should not be interchanged. 4. A comparator kit containing a suitable range of standards. Sec.A.1.2 Reagents 1. DPD indicator solution. Prepare as prescribed in Standard Methods for the Examination of Water and Wastewater. Sec.A.1.3 Procedure 1. Add 10 drops of DPD solution and 10 drops of buffer solution (or 20 drops of combined DPD-buffer solution) to a comparator cell. 2. Fill the comparator cell to the 10-mL mark with distilled water. 3.

Chlorine Residual: Concentration of chlorine species present in water after the oxidant demand has been satisfied. Sodium hypochlorite: Sodium hypochlorite contains approximately 5 percent to 15 percent available chlorine South Tahoe Public Utility District 2 Disinfection and Testing Guide Updated:July 2016 (V1-jhr) I. Introduction This Disinfection and Testing Guide has been developed to instruct Contractors in the minimum accepted methods by which new water connections to the existing public water system are tested and disinfected for acceptance.The methods that will be presented are from the latest edition of the American Water Works Association (A.W.W.A) Disinfection Procedures C651, and the District's Standard Specifications.The Contractor shall not deviate from any of the requirements of this Guide without written District consent. At no time shall a new portion of pipeline be connected to the District's existing Water System until the new pipeline has been properly disinfected and has passed all bacteriological tests. II. Procedure Prior to beginning work Owner or Contractor shall develop and provide to the District a written Disinfection Procedure incorporating the requirements below. Only liquid chlorine, Sodium Hypochlorite is allowed to be used for disinfection. Potable water may be supplied from a temporary backflow-protected connection to the existing distribution system or other supply source approved by the District. The backflow assembly shall be a District tested and Approved Reduced Pressure Principle backflow assembly(see Figure 1). III. Initial Tie In Connection Tie in to the existing District's Water System will be conducted by Hot Tap or Cut In method. Cut-In Method Cut In method may be performed by the Contractor, and must be closely coordinated with District Staff to notify affected Customers and to facilitate the shut-down of the District's Water System at the Tie in point. At no time is the Contractor or any other non-District personnel allowed to operate existing valves on the District's Water System.The installation work must be conducted in a safe and sanitary condition.The pipe trench shall be continuously dewatered to maintain the water level well below the open pipe ends. All new materials to be installed, tools, and all exposed surfaces of the existing pipe shall be kept clean and sanitary by spraying and swabbing with sodium hypochlorite. Hot Tap Method If a Hot Tap is selected,the work to tap the main will be performed by the District, with advance notice. The saddle and valve are to be provided and installed on the main by the Owner's Contractor. Scheduling with District for Hot Tap or Shut Down shall be in writing a minimum of 2 working days. Following the hot tap, disinfection and bacteriological tests will be conducted by trained District personnel from a nearby sampling location on the existing system. IV. Leak Testing Assembled piping and appurtenances from the point of tie in at the existing District Water System to the terminus point of the new pipeline (generally defined by a service valve or backflow protection device), shall be tested for leaks.The method of leak testing shall be determined based on the assembled length of the new piping and appurtenances (fittings and valves). Assembled Length of 20 linear feet or less Assembled piping of 20 linear feet(If) or less shall be visually inspected for leaks by District personnel after it has been assembled, disinfected, installed, and charged. To facilitate inspection, the Contractor shall not backfill the trench until South Tahoe Public Utility District 3 Disinfection and Testing Guide Updated:July 2016 (V1-jhr) after the new piping is charged to system pressure, and District personnel have completed the visual inspection. For safety,the Contractor is required to restrain and/or brace the exposed piping to District satisfaction before the line is charged by the District.At no time is the Contractor or any other non-District personnel allowed to operate existing valves on the District's Water System. Assembled Length of greater than 201f Assembled piping of greater than 201f shall be hydrostatically pressure-tested prior to being disinfected and connected to the District's Water System, for a minimum of 2 hours at the rated pressure for the assembled piping (typically 150 psi), as measured at the lowest point in the line.To test, accurately measure the makeup water necessary to maintain the pressure in the piping section under test during the pressure test period. Successful completion of the pressure test with maximum leakage allowance shall have been achieved when the observed leakage during the test period is equal or less than the allowable leakage and no damage to piping and appurtenances has occurred. Calculate the allowable leakage by the following formula. L = (S*D*-FP) 133,200 Wherein the terms shall mean: L=Allowable leakage in gallons per hour. S= Length of the test section in feet. D = Nominal diameter of the piping in inches. P=Average observed test pressure in pounds per square inches, gauge, at the lowest point of the test section, corrected for elevation of the pressure gauge. V. Disinfection New tie-in fittings and valves shall not be connected to the District's Water System until they have been disinfected. New piping shall not be connected to the tie-in fittings and valves until it has been disinfected, flushed (if necessary) and tested.The method of disinfection shall be determined based on the assembled length of the new piping and appurtenances (fittings and valves),from the point of tie in at the existing District Water System to the terminus point of the new pipeline (generally defined by a service valve or backflow protection device). Assembled Length of 20 linear feet or less Pipeline installations of 20 linear feet(If) or less shall be spray disinfected and swabbed with sodium hypochlorite immediately before being installed. Because the entire interior of the assembled piping is visible, it shall be inspected for particulate contamination and re-swabbed, if necessary, prior to installation; flushing is not required. Assembled Length of greater than 201f Pipeline installations of greater than 201f shall be protected from contaminating materials from entering the pipe and appurtenances during storage, construction, or repair and noting potential contamination at the construction site. Upon completion of installation and successful hydrostatic testing as required by District, remove particulate materials that may have entered the water main or appurtenances by flushing or other means, prior to proceeding with disinfection. The flushing velocity in the main shall not be less than 3.0 ft/sec.Table 1 shows the rates of flow required to produce a velocity of 3.0ft/sec. in commonly used sizes of pipe. (NOTE:flushing is no substitute for preventive measures during construction. Certain contaminants, such as caked deposits, resist flushing at any feasible velocity, and South Tahoe Public Utility District 4 Disinfection and Testing Guide Updated:July 2016 (V1-jhr) pigging of the main, or other suitable method acceptable to the District, may be required.) Where such flow rates are not possible, flushing at the maximum expected flow rate for the line for 2-3 volumes may be allowed with approval from the District. To disinfect, at a point not more than 5 ft downstream from the beginning of the new main,water entering the new main shall receive a dose of chlorine fed at a constant rate such that the water will have not less than 25mg/L free chlorine. To ensure that an appropriate concentration is achieved,the free chlorine concentration shall be measured at regular time intervals in accordance with the procedures described.Table 2 gives the amount of chlorine required for each 100 ft of pipe for various pipe diameters. Solutions with a minimum 1 percent chlorine concentration may be prepared with sodium hypochlorite. Chlorine application shall not cease until the entire main is filled with chlorinated water.The chlorinated water shall be retained in the main for at least 24 hr., during which time valves and hydrants in the treated section shall be operated to ensure disinfection of the appurtenances. At the end of this 24-hr period, the treated water in all portions of the main shall have a residual of not less than 10 mg/L of free chlorine as determined by District Lab personnel.After the applicable retention period, heavily chlorinated water should not remain in prolonged contact with pipe. In order to prevent damage to the pipe lining or to prevent corrosion damage to the pipe itself,the heavily chlorinated water shall be flushed from the main fittings,valves, and branches until chlorine measurements show that the concentration in the water leaving the main is no higher than that generally prevailing in the distribution system or that is acceptable for domestic use. Chorlinated water shall be disposed of appropriately, and shall not be discharged to the District's Sewer System without prior written consent. After disinfection,the chlorinated water in the new pipe shall be replaced with water at background chlorine level, prior to collecting samples for bacteriological testing. VI. Bacteriological Testing Bacteriological Testing will be performed on all assembled piping. Assembled Length of 20 If or less Samples will be collected by District personnel from a nearby sampling port on the existing system after the new piping has been connected to the system. Assembled Length of greater than 201f Prior to connection of the new piping to the existing system, District staff will collect samples for every 1,200ft of the new pipeline and appurtenances, plus one set from the end of the line and at least one from each branch greater than one pipe length,for a minimum of three test sites per 1200 feet of new assembled piping. The sample ports shall be installed by the Contractor(see Figure 2). The District has two options for the bacteriological testing for total coliform analysis. Option A: Before approving a main for release,take an initial set of samples and then resample again after a minimum of 16 hr. using the sampling site procedures outlined. Both sets of samples must pass for the main to be approved by the District's lab for release. Option B: Before approving a main for release, let it sit for a minimum of 16 hr. without any water use.Then collect, using the sampling site procedures outlined and without flushing the main,two sets of samples a minimum of 15 min apart while the sampling taps are left running. Both sets of samples must pass for the main to be approved for release.A standard Heterotrophic Plate Count (HPC)test may be required at the option of the District because new mains do not typically contain coliform bacteria but often contain HPC bacteria. If sample results show HPC greater than 500 CFU/mL, South Tahoe Public Utility District 5 Disinfection and Testing Guide Updated:July 2016 (V1-jhr) flushing should resume and another set of HPC and coliform samples collected until no coliform are present and the HPC is less than 500 CFU/mL. If the initial disinfection fails to produce satisfactory bacteriological results, or if other results indicate unacceptable water quality, the main may be reflushed and shall be resampled. If check samples fail to produce acceptable results,the main shall be rechlorinated until satisfactory results are obtained. VII. Final Connection Assembled Length of greater than 201f Water mains and appurtenances must be completely aseembled,flushed (when required), disinfected, and satisfactory bacteriological sample results received (when required) prior to permanent connections being made to the active distribution system. Sanitary construction practices must be followed during installation of the final connection so that there is no contamination of the new or existing water main with foreign material or groundwater.

END OF SECTION MARCH 2026 SECTION 35 10 00 2026 WATER METER INSTALLATION PROJECT WATER METERS, LIDS AND FRAMES 2 REPORTS APPENDIX A BABA WAIVER - AMI METERS Approved: December 20,2024 Expires: December 19,2027 DEPARTMENT OF THE INTERIOR Bureau of Reclamation and The U.S. Environmental Protection Agency General Applicability Non-Availability Waiver Build America,Buy America Product Waiver: AMI Water Meters 1. Summary Agency: Department of the Interior(DOI/Department)'s Bureau of Reclamation(USBR) and the U.S. Environmental Protection Agency (EPA) Final Waiver: The Department is joining the EPA to issue a partial general applicability/nonavailability waiver of the requirements of section 70914 of the Build America, Buy America Act included in the Infrastructure Investment and Jobs Act(Pub. L. No. 117-58) for Advanced Metering Infrastructure (AMI)water meters used in infrastructure projects funded through USBR and the EPA, while requiring certain components of the water meters to be manufactured in the United States according to the phased implementation schedule below. This waiver is in effect for three (3) years from the date of approval. DOI and the EPA are implementing a phased approach during the waiver period, whereby, for two years from the date of approval,purchases of AMI meters and all components (the entire "manufactured product") are waived. Two (2) years from the date of approval, AMI meter housings shall be domestically manufactured or produced and excluded from the waiver scope; all other components continue to be waived through the end of the three-year period. This waiver only applies to products purchased after the effective date of this waiver and may not be used for products purchased after the expiration date of the waiver. At the conclusion of the full three-year waiver period, DOI and the EPA expect AMI water meters to be manufactured in the United States and their total cost of components to be greater than 55 percent domestically manufactured or produced. Waiver type: Nonavailability of domestic products Waiver level: General Applicability, Product level waiver Waiver justification summary: There are no AMI water meters manufactured in the United States meeting BABA's 55 percent total cost of components domestic content requirement. Length of the waiver: This waiver is in effect for three (3) years from the date of approval. DOI and the EPA are implementing a phased approach during the waiver period, whereby, for two years from the date of approval, purchases of AMI meters and all components (the entire "manufactured product") are waived. Two (2)years from the date of approval, AMI meter housings shall be domestically manufactured or produced components and will be excluded from the waiver scope. This waiver only applies to products purchased after the effective date of this waiver and may not be used for products purchased after the expiration date of the waiver. Summary of items covered in the waiver: • AMI water meters. 1 NAICS: 334514 PSC: 6632 2. Background The Buy America Preference set forth in section 70914 of the Build America, Buy America Act included in the Infrastructure Investment and Jobs Act(Pub. L. No. 117-58), requires all iron, steel, manufactured products, and construction materials used for infrastructure projects under Federal financial assistance awards be produced in the United States. Under section 70914(b), a Federal agency may waive the application of the Buy America Preference, in any case in which it finds that: applying the domestic content procurement preference would be inconsistent with the public interest; types of iron, steel, manufactured products, or construction materials are not produced in the United States in sufficient and reasonably available quantities or of a satisfactory quality; or the inclusion of iron, steel, manufactured products, or construction materials produced in the United States will increase the cost of the overall project by more than 25 percent. All waivers must have a written explanation for the proposed determination; provide a period of not less than 15 calendar days for public comment on the waiver; and submit the waiver to the Office of Management and Budget Made in America Office for review to determine if the waiver is consistent with policy. 3. Description of Covered Items Manufactured products: AMI water meters collect water usage information. When used as a fixed network across a community, AMI water meters automatically collect and store consumption data, aiding in water conservation and water use efficiency, improved water management, and energy savings. Information provided helps identify high water usage that could indicate leaks,providing time sensitive leak detection alerts. AMI water meter networks reduce water demand by enhancing conservation, reduce energy use/operating costs, and reduce carbon emissions using remote/automated meter reads. AMI water meters are composed of meter housings, end points/transmitters,printed circuit boards, meter electronics, batteries, base stations, repeaters and associated equipment. Based on market research completed within the last two years, some manufacturers source the materials for the meter housings domestically. A few manufacturers indicated that their meter housings are 100 percent manufactured or produced within the United States. However, the industry universally sources the end points/transmitters, printed circuit boards, meter electronics, and batteries internationally. As these components are the most expensive parts of the water meter, the meter system as a whole does not meet BABA's 55 percent of total cost of components domestic content requirement. Based on the market research described below, there are currently no AMI water meters manufactured domestically that meet BABA requirements. 4. Waiver Justification Based on cumulative and collaborative market research efforts, DOI and the EPA are issuing a three-year waiver split into two phases. In the first phase, a waiver shall be provided for two years from the date of approval to cover AMI meters and all their components. Two (2)years 2 from the date of approval, AMI meter housings shall be a domestically manufactured or produced component,but other AMI water meter components will continue to be waived. At the conclusion of the three-year waiver period, DOI and the EPA anticipate that AMI water meters (i.e.,bundled with their component parts) will be available as a manufactured product with 55 percent or more of the components domestically manufactured or produced. This waiver's purpose is to incentivize production of BABA compliant AMI water meters. Based on stakeholder feedback, DOI and the EPA have identified that significant challenges prevent AMI water meters from being BABA compliant. However, with appropriate market signals, AMI water meters could be BABA compliant by the expiration of the waiver. DOI and the EPA are seeking this waiver specifically to send the appropriate market signals to the AMI water meter manufacturing community. DOI and the EPA's expectation is that AMI water meters be BABA compliant. This waiver identifies a realistic phased pathway for domestic manufacture of these products, first by targeting the domestic manufacture of meter housings, with the second phase for the remaining components of an AMI water meter that are not currently available to be manufactured or produced within the United States. As an incentive, while this waiver is active, manufacturers may still receive the benefit of Federal funding by providing products to be used under Federal awards, with the phased approach rewarding those manufacturers that take advantage of the waiver period to transition to domestic content. Anticipated impact if no waiver were issued: DOI's USBR provides annual funding for the competitive Water and Energy Efficiency Grant(WEEG)program, which regularly funds AMI water meter projects. As no BABA compliant AMI water meter is available, there is no alternative but for these projects to be covered by a product or project waiver. In FY23 alone, USBR's WEEG program competitively selected water meter grants totaling $43 million Federal and $90 million non-Federal funding. This $134 million investment is expected to result in an annual water savings of over 20,000 acre-feet. Based on historical data, the EPA anticipates that at least 10 percent of all EPA funded water infrastructure projects will purchase and install AMI water meters. The majority of these will occur through the State Revolving Fund, the Water Infrastructure Finance and Innovation Act program, and other funding programs. As no BABA compliant AMI water meter is available, there is no alternative but for these projects to be covered by a product or project waiver. In the absence of this waiver, DOI, the EPA, and the Federal grant-making community will miss an opportunity to clearly articulate expectations for creating a domestically manufactured or produced market to the AMI water meter manufacturing community. This could have the impact of slowing the long-term domestic sourcing transition, and curtailing Federal participation in AMI water meter projects, which would weaken support for communities throughout the West that are struggling to conserve their declining water supply. Market Research to Justify Product Non-Availability Waiver: From 2022 through 2024, DOI, the EPA, and grant recipients conducted market research to assess the availability of domestically manufactured AMI water meters. As a result of this cumulative market research, there is no known manufacturer of AMI water meters, that meet BABA's domestic production requirements. 3 All manufacturers responsive to market research inquiries stated that they are in the process of evaluating the idea of moving manufacturing to the U.S.,but have no immediate plans or timeframes identified. As there are upwards of fifty(50) components to an AMI water meter system, evaluating the domestic sourcing of the manufactured product as a whole through the component cost break down is a significant effort. Should key high-cost components of an AMI water meter be manufactured within the U.S. in the future, this could lead to a domestically produced manufactured product meeting the 55 percent BABA requirement. DOI and the EPA considered whether an AMI water meter waiver could target certain components, such as the internal electronics and end points, rather than the AMI water meter as a whole. Transmitters,printed circuit boards, meter electronics, batteries, and end points used within AMI water meters were identified as the components most difficult to source domestically. Market research feedback has indicated that one component of the AMI meter-- the meter housings -- are manufactured domestically by several manufacturers. However, BABA-compliant water meter housings are not available immediately in sufficient quantities to meet demand, nor are they universally compatible. This waiver, through the phased approach, reflects market research and public comments confirming that water meter housing components can be manufactured domestically within two years. DOI and the EPA also considered whether this waiver could be targeted to AMI water meters below a size threshold but found no evidence to support targeting specific size thresholds. To gain additional industry feedback on materials used in water infrastructure products, such as AMI water meters, the EPA published a Request for Information (RFI)Request for Information Regarding Products and Categories of Products Used in Water Infrastructure Programs in the Federal Register on November 20, 2023, which closed on December 20, 2023, EPA-HQ-OW- 2023-0396-0001). The RFI requested feedback detailing domestic materials sourcing, market readiness, other product supply considerations, and whether water infrastructure products are manufactured in the U.S. The EPA and DOI examined the 12 comments that provided feedback on the domestic availability of water meters. In general, commentors to the RFI noted that manufacturers need time to assess, design, develop, and test new lines of domestically produced products consistent with BABA requirements. Component changes on manufactured goods require re-evaluation periods to reduce major issues in manufacturing. This includes establishing new domestic production facilities, new BABA compliant lines of domestic products, and staffing for the new facilities. Commenters also reported significant concerns with stocking burdens, customer communication issues, and production capacity issues. Commenters noted that there are significant issues related to the domestic sourcing of electronics. Commenters note that there is no support to offset the foreign procurement of the electronics. One commentor shared that they were unlikely to meet the BABA domestic component sourcing requirements within five years, as the effort requires a significant time and funding investment. Given that it is not possible for all future funded AMI water meter projects to source the meter housings from the few domestic sources, (for the above described compatibility and market lead times concerns), DOI and the EPA are issuing a time-limited three-year phased waiver, in which all components of the water meter product are waived in phase one. This initial, two-year phase 4 of the waiver covers all components of the AMI smart meter to provide an opportunity for manufacturers to assess the sourcing of their meter housings and transition to a domestic supply for that component. The second phase of this waiver, which begins two (2) years from the date of approval, extends waiver coverage to components of the AMI water meter except the meter housing, for the third of three years, whereby AMI water meter housings will be required to be domestically manufactured at that time. DOI and the EPA consider this waiver to provide a significant market signal and time for manufacturers to analyze current issues and develop strategies to create domestically manufactured or produced products that are consistent with BABA requirements. This will also give time to assess, design, develop, and test new lines of the domestic products. Responses to the EPA's RFI were generally consistent with the feedback DOI had previously received. DOI and the EPA consider this waiver's incentive-based approach to be appropriate and fair for both manufacturers that have manufactured or produced some of their AMI water meter components domestically and those that have not prioritized a domestic supply of components prior to the enactment of the Infrastructure Investment and Jobs Act, sometimes referred to the Bipartisan Infrastructure Law. Manufacturers not sourcing their components domestically will have sufficient and reasonable time to reassess,plan, and implement changes. Manufacturers currently sourcing some of their products domestically will have sufficient and reasonable time to source the high-cost components of AMI water meters domestically. While the industry as a whole manages this transition, DOI and the EPA may continue to fund projects to conserve and efficiently use water resources through the use of AMI water meters. An analysis will be required immediately prior to the conclusion of the waiver period to identify how the AMI water meter industry has shifted in response to changing market conditions. Expectation for the agency, award recipients, and industry at the conclusion of the waiver: DOI and the EPA expect to continue to engage in conversations with grant recipients and other Federal agencies to encourage the AMI water meter manufacturing industry to meet the 55 percent of total cost domestic content requirement for BABA compliance. DOI and the EPA will review this waiver annually to assess whether it remains necessary. DOI and the EPA may, based on the results of that review, terminate, or narrow the scope or duration of this waiver, or take such other action deemed as appropriate. 5. Assessment of Cost Advantage of a Foreign-Sourced Product Under OMB Memorandum M-24-02, Federal agencies are expected to assess "whether a significant portion of any cost advantage of a foreign-sourced product is the result of the use of dumped steel, iron, or manufactured products or the use of injuriously subsidized steel, iron, or manufactured products" as appropriate before granting a public interest waiver. DOI and the EPA's analysis has concluded that this assessment is not applicable to this waiver as this waiver is not based on the cost of foreign-sourced products. 5 6. Summary of Public Comments The waiver received sixteen(16)public comments over the thirty (30) day publication period from August 30, 2024 through September 28, 2024. Five (5)municipal water authorities, four (4) manufacturing entities, three (3) state revolving fund programs, two (2) water infrastructure associations, one (1) national manufacturing association, and one (1) consulting engineer submitted comments. None of the comments opposed the waiver, in general. Most comments included detailed information for consideration, all of which were substantive. While commenters expressed support for the waiver generally, many raised concerns with aspects of the waiver including the phasing and overall duration, component specificity, nomenclature, and scope. Many commenters requested the waiver duration be extended beyond the three years proposed, noting that additional time appears necessary to scale up and build production for the potential demand cited in the proposal. DOI and the EPA considered the comments regarding waiver duration and determined that the points raised did not warrant extension beyond the proposed three-year duration. Market research for this waiver identified several domestic manufacturing entities that have made recent investments in domestic manufacturing, and comments to the waiver confirm that increasing domestic supply will be available nearing the end of the waiver period. Extension of the waiver beyond three years may disincentivize potential investment and expansion of the developing domestic sources. Before the conclusion of the waiver, DOI and the EPA will re-evaluate the conditions of supply chains for water meters. Should domestic availability continue to be a concern and the identified domestic manufacturing base is unable to ramp up production to meet expected demand, the expiring waiver will be re-considered. Comments also asked for clarification on the timing of the waiver phases, noting that the language in the proposal caused some confusion about the sequence of the phases whereby some commenters interpreted the total waiver time period as five years, which was not the intent of the proposal. This final waiver includes adjusted language to clarify the phases of the waiver, as follows: The first phase, which is two (2)years in duration, covers AMI meters and all their components. Two (2)years from the date of approval, AMI meter housings shall be a domestically manufactured or produced component, but all other components continue to be waived for the final year of the waiver. The total duration of the waiver is three (3) years. Several comments expressed concerns with terminology used in the waiver, including references to water meter "bodies" and "resins," in addition to requesting clarification regarding the components of a water meter manufactured product. The consensus of comments recommended changing "bodies" to "housings" to clarify and avoid confusion, a change which is reflected in the final waiver. Additionally, comments recommended striking "resins" from inclusion in the components list describing typical water meter products, noting that the resins are typically input materials that are used to produce components (such as meter housings), and therefore are not directly incorporated into the final manufactured product. The term "resins" has been removed from the final waiver. The final waiver does not, however, include any other changes in reference to the components of a water meter product. DOI and the EPA examined the comments and while the consensus of comments requests delineation of all known, specific components of a water meter product, or to refer to the products as "systems," the final waiver is unchanged from the proposal in this aspect. Several comments noted that the technologies can differ 6 significantly across brands and models, and that products are evolving rapidly. In order to avoid confusion and mischaracterization of product types, the final waiver retains the example list of water meter product components (such as meter housings, end points/transmitters,printed circuit boards, meter electronics, batteries, base stations, repeaters, and associated equipment), noting that components can differ depending on the water meter system in use or the needs of specific projects. DOI and the EPA view this list of components as a reasonable instructive example of what comprises a water meter manufactured product. The waiver requested comments regarding the substitutability and compatibility of meter housings and meters from different manufacturers. Six(6) commenters responded that AMI water meters from different manufacturers are not compatible without loss of"AMI" features. One (1) commenter shared that intermingling components would likely void product warranties. DOI and EPA, therefore, consider it important to provide sufficient time and appropriate phasing of this waiver to encourage a market-wide domestic sourcing transition. The waiver requested comments regarding a potential domestic assembly requirement, to which two (2) commenters responded substantively. One (1) commenter requested expanding the timeframe of the waiver significantly in order to include a domestic assembly requirement after four(4)years. Another commenter responded noting that they could presently domestically assemble a portion of the projected national supply for AMI water meters and could expand that domestic assembly capability to a larger portion (though far less than half of the total) of the demand with further investment,but the timing for the expansion was not provided. While DOI and the EPA appreciate the manufacturing entities' encouraging efforts toward domestic assembly, and strongly recommend recipients to utilize domestically assembled water meters when available, comments did not indicate market readiness for domestic assembly across the industry. The comments did not address or remove concerns that including a domestic assembly requirement within the three-year waiver period would alleviate existing supply chain issues. In light of many comments received emphasizing compatibility issues for municipal projects, the evidence for domestic assembly sourcing to supply the wide range and full projected needs of recipient projects does not warrant inclusion of an assembly requirement during the waiver period. The waiver applies coverage at the point of purchase. Several comments requested that the final waiver include a change or further clarification to the applicability point for the acquisition of water meters. DOI and the EPA consider the purchase date stipulation to be a clear signal point of waiver applicability for manufacturers and a workable definition for recipients and oversight authorities. Other commenter suggested reference points could create confusion between manufacturers and recipients,ultimately undermining the waiver intent and potentially inviting noncompliance through misapplication of the waiver. The EPA has demonstrated success from past national waivers with the use of purchase date as the waiver applicability point,providing clarity for manufacturers, financial assistance recipients (including sub-recipients), and compliance oversight authorities. Several comments requested expansion of the waiver to include other types of flow meters beyond AMI water meters. DOI and the EPA are not expanding the waiver to include additional meter types at this time. Although the comments shared supply chain concerns for additional 7 meter types, the information available does not provide sufficient detail to support expansion of the waiver. DOI and the EPA will continue to evaluate supply chains for these products and may examine future waiver actions based on additional market research or project-specific waiver requests. Multiple commenters requested the waiver apply to projects with AMI water meter projects already underway, noting that supply chain issues identified in the waiver apply to current activity equally as to future purchases. DOI and the EPA acknowledge that active water meter projects that have already received federal financial assistance for AMI smart water meters are not within the scope of this waiver, noting that extension of this waiver for these situations would "retroactively" apply the waiver, a policy prohibited through M-24-02. If a project has concerns or uncertainty about the status of their project relative to this waiver, DOI and the EPA recommend that projects contact the appropriate funding authority to discuss the specifics of ongoing projects.

L. No. 117-58) for AMI water meters used in infrastructure projects. Michael S.
