Lead and Copper Rule Revisions

Service Line Inventory requirements in the Lead and Copper Rule Revisions (LCRR)

The Lead and Copper Rule applies to all Community (CWS) and Non-Transient (NTNC) public water systems. EPA adopted revisions to the Lead and Copper Rule in 2021 that include a requirement for public water systems to conduct inventories of service lines and to identify service line material type. The intent of the service line inventory requirement is to identify those service lines made of lead so that they can be scheduled for removal and replacement.

Public water systems must conduct an inventory of all service lines, on both the water system side and the homeowner side of the meter, and to submit the results to OHA–Drinking Water Services (DWS) by October 16, 2024.

Assistance is available from two organizations to assist your water system in completing and submitting the service line inventory. Information will be sent to water systems relaying contact information and how they can assist you with the inventory requirement.

Funding Resources

BIL Lead Service Line Replacement (BIL-LSLR) Funding
OHA in partnership with Business Oregon is intending to apply for federal funding to support lead service line inventory work and for the replacement of lead service lines, galvanized requiring placement and connectors. Eligible water systems include publicly and privately owned community systems and non-profit non-community systems.

Program Description

  • Funding will support lead service line inventory work and the replacement of lead service lines, including goosenecks, pigtails, and connectors. For a list of activities which are considered eligible or ineligible, please refer to the BIL-Lead Service Line Replacement Funding Eligibilities Handout.

  • When replacing lead service lines, the project must replace the entire lead service line, not just a portion, unless a portion has already been replaced. Projects must fully replace both the public and private side up to the point of premise plumbing.

  • Funding will be available to eligible water systems in the form of low interest loans. Under this federal funding program, 49% of annual state appropriations must be in the form of additional subsidy (i.e., principal forgiveness) allocated to disadvantaged communities.

  • Application to EPA for this federal funding is planned for mid-summer 2024 and we anticipate receiving the funds by mid fall. Invitation for water systems to move forward and receive a funding contract in this program is expected to begin late 2024 to early 2025. Money will not be available prior to the required lead service line inventory submittal deadline but can be used for future inventory related work.

How to Apply

LOI submission is closed for 2024. Stay tuned for future funding opportunities. 

General Information
  • Eligible water systems must submit a Letter of Interest (LOI) form by the submission deadline. Projects are reviewed, rated, and ranked annually and placed on a project priority list which is used to allocate funding.
  • For specific questions related to filling out the LOI, contact the Regional Development Officer for the area in which the water system is located. Water systems that need further help filling out and submitting the LOI to Business Oregon are referred to OHA’s Circuit Rider Program.
