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.


Survey of Public Water Systems on Lead Service Lines and Emerging Contaminants

This survey (5-10 minutes) is intended to gather information about Public Water System needs related to two topics:

  1. completing required inventories of service lines; and
  2. addressing emerging contaminants.

The results will help Drinking Water Services determine state grant needs from funding available to Oregon by the Bipartisan Infrastructure Law.
