Subject: Approval of a Cost Sharing Agreement with the Municipal Water District of Orange County for assistance with federal and state compliance to develop a Water Service Line Inventory. (Cost: $235,580) (Action Item)
OBJECTIVE
To request that City Council approve a Cost Sharing Agreement with the Municipal Water District of Orange County (MWDOC) to assist the City in developing a 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 inv entory 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 Bo ard (SWRCB), who will be reviewing the plan and reporting back to USEPA on compliance efforts made by local agencies.
The inventory process will involve the following steps:
Desktop Analysis - determine service line materials using historical records (e.g. construction and plumbing codes, customer -side construction permits, distribution system records), and building an initial service line inventory. Field Verifications- after desktop analysis is completed, the remaining unknown services lines will be identified by conducting a three-point field verification at the meter box (agency-side and customer-side service lines) and at the riser immediately before the connection enters the building. A statistical analysis Item 91/2024
and predictive modeling approved by SWRCB, wi ll be used for selective sampling to reduce the amount of field verifications needed.
