Equipment will conform to the following requirements: 1. Equipment— Desiccant dehumidifiers will be a solid desiccant design having a single rotary desiccant wheel capable of fully automatic continuous operation. No liquid, granular, or loose lithium chloride drying systems will be accepted. The use of direct expansion (DX) refrigeration type dehumidifiers with reheat may be considered if the expected ambient temperature will remain above 60°F. Heating the space changes relative humidity only and does not change FEBRUARY 2026 SECTION 09 97 13.23 2026 STATELINE TANKS EXTERIOR COATING FOR WELDED STEEL RESERVOIR RECOATING PROJECT-Addendum No.1 14 the dew point temperature. Heat alone, therefore, is not a substitute for dehumidification, unless substrate temperature is high enough to meet the dew point differential. The dehumidification system may consist of a combination of desiccant and refrigerant equipment. 2. Air Changes —The air change rate for maintaining the required spread of 10°F between inside surface temperature and inside space dew point temperature with a maximum relative humidity of 60% in the space will depend upon the type of equipment to be used and the time of year during the application. There shall be 1 to 4 air changes per hour, depending on the air volume of the space to be controlled, to hold the desired degree of cleanliness of the surface. C. Temperature Control —Auxiliary cooling or insulation may be necessary to maintain the surface temperature at an acceptable level for the coating manufacturer's application parameters. This auxiliary equipment must be approved for use by the supplier of the dehumidification equipment and will meet the following requirements. 1. Refrigerant type systems must be installed in the process air supply duct between, and/or blended with, the dehumidifier as close to the work space as possible. 2. Only electric, indirect fired combustion, or steam coil auxiliary heaters will be used. No direct-fired space heaters will be allowed during the blasting, coating, or curing phases. 3. The space to be controlled will be sealed off as well as possible, allowing air to escape the work space away from the point where the dehumidified air is being introduced. If it is necessary to filter the air escaping the space, the filtration system must be designed so that it does not interfere with the dehumidification equipment's ability to control the dew point and relative humidity of the work space. 3.05 PREPARATION FOR COATING A. A heavy-duty, fire retardant, seamless, shrink-wrap polyethylene sheet treated with UV inhibitors containment system shall be utilized for abrasive blasting and spray coating applications on the exterior of the tank.

DISCUSSION: The 2026 Advanced Metering Infrastructure (AMI) Water Meter Installation Project represents the final phase of installing water meters for all District customers. California Assembly Bill 2572 requires all urban water suppliers to install meters on all service connections, and completion of this Project will bring the District into compliance with that requirement. This Project will install meters at seventy-two (72) remaining properties that do not currently have meters. Many of these services are located in the Loop Road area and along Roger Avenue, where some services are connected through backyards, with additional locations distributed throughout the District's service area. The District has previously completed six phases of meter installation projects, all of which utilized Sensus meters. For this final phase, District staff recommends that the Board find Sensus as the sole-brand allowable meter to match equipment already in use throughout the District's water system, as permitted under Public Contract Code Section 3400(c). The Project is partially funded by a Bureau of Reclamation grant totaling $483,437. The Engineer's Estimate for the Project is $967,800. District staff anticipate advertising for bids on March 27, 2026, with a recommendation for award to be brought to the Board at the May 21, 2026, meeting.

DISCUSSION: The Claimant, Charter Communications, filed a Claim against the District on February 10, 2026, for alleged damage to a buried cable line and conduit. The Claimant alleges that on July 8, 2025, District crew excavated outside of the work area described in the Underground Service Alert (USA) dig ticket created by the District's Underground Repair Water crew and dug through a buried cable line. The Joint Powers Insurance Authority (JPIA) has reviewed this Claim and recommends that the District reject the Claim on the grounds that staff confirmed that the District's excavation did occur within the work area the District delineated at the site. The dig ticket contains a polygon roughly outlining the work area, but the definitive delineation of the proposed dig area is marked by white paint on the street at the dig location. The buried cable line that the District's water crew damaged was located within the area delineated by the white paint, and there were no utility marks indicating buried assets near the excavation. The District can reject a Claim, allow a Claim, reject or allow a Claim in part, or compromise a Claim. If the District does not take action on the Claim within the six- month timeframe, the Claim is deemed rejected on the last day of that period. Once the Claim is deemed rejected, the Claimants may file a lawsuit. If written notice is not given that the Claim was rejected or deemed rejected, a two-year statute of limitations applies to the Claim. In contrast, rejection of the Claim coupled with a notice of rejection triggers a shorter six-month limitations period in which to file a lawsuit. Staff recommends that the District reject the Claim.
