Dept:
City Manager Dept: Public Works
Date: April 23, 2024
Subject: Approval of Amendment No. 1 to Cost Sharing Agreement with the Municipal Water District of Orange County for assistance with Field Verifications for the Water Service Line Inventory. (Cost: $226,336) (Action Item)
OBJECTIVE
To request that City Council approve Amendment No. 1 to the Cost Sharing Agreement with the Municipal Water District of Orange County (MWDOC) to assist the City in field verifications for the water service line inventory to comply with federal and state regulations.
BACKGROUND
In January 2021, the US Environmental Protection Agency (USEPA) published the Lead and Copper Rule Revisions (LCRR) requiring all water systems to complete a service line inventory specifying pipe material containing lead or non-lead. This service line inventory includes both agency-side and customer-side water service lines. If lead lines are found, a replacement plan must be developed. The initial inventory is due on October 16, 2024. The inventory will be submitted to the State Water Resources Control Board (SWRCB), who will be reviewing the plan and reporting back to USEPA on compliance efforts made by local agencies.
On January 23, 2024, the City entered into a cost sharing agreement with the Municipal Water District of Orange County’s (MWDOC) contractor, Hazen and Sawyer, to assist in the desktop analysis of records for establishing a water service line inventory of pipe materials for the city-owned service lines. This phase of the project has been completed. The next phase of the project is to complete visual field verifications of pipe materials for privately owned service lines.
DISCUSSION
Hazen and Sawyer coordinated with the SWRCB to obtain an approved method of selective sampling to reduce the amount of visual field verifications needed. A selective sampling of 2,003 unknown services lines will need to be identified by conducting a three-point field verification at the meter box (agency-side and customer-side service lines) and at the riser Item 84/2024
immediately before the connection enters the building. The City’s cost in participating in this phase of the project will be $226,336.
FINANCIAL IMPACT
There is no impact to the General Fund. The City's share of the project cost is $226,336.
The cost is included in the City’s adopted FY 2023-25 Water Enterprise Fund budget.
RECOMMENDATION
It is recommended that the City Council:
• Approve the attached Amendment No. 1 to the Cost Sharing Agreement with the Municipal Water District of Orange County to assist the City in field verifications for the water service line inventory to comply with federal and state regulations, in the amount of, not to exceed $226,336; and
• Authorize the City Manager to execute the amendment agreement on behalf of the City and make minor modifications as appropriate thereto.
