Lead and Copper Rule Revisions

The Lead and Copper Rule Revisions (LCRR) amend the Lead and Copper Rule. All community and non-transient non-community public water systems are required to comply with the LCRR starting October 16, 2024. On this page, find information related to the rule including provisions for service line inventories and testing in schools and child care facilities.

The Environmental Protection Agency (EPA) announced final revisions to the National Primary Drinking Water Regulations for lead and copper under the authority of the Safe Drinking Water Act on December 16, 2021. 

EPA has also announced an additional update to lead and copper rules called Lead and Copper Rule Improvements, to strengthen key elements of LCRR. According to EPA this additional rulemaking is expected prior to October 16, 2024.

Public Water Systems

The LCRR is in effect with a compliance date of October 16, 2024. The rule revisions will apply to all community water systems (CWS) and non-transient non-community water systems (NTNC). These PWSs should continue to implement the current LCR sampling, compliance, and reporting requirements as in Title 30, Texas Administrative Code, Section 290.117Exit the TCEQ and on TCEQ’s Lead and Copper webpage.

Implementation is being discussed during Drinking Water Advisory Work Group (DWAWG) meetings.

TCEQ will continue to use the work group to engage regularly with the public drinking water community on this topic.

Service Line Inventories

CWSs and NTNCs must submit service line inventories to TCEQ no later than October 16, 2024.

TCEQ is developing guidance documents and resources including Service Line Inventories for Public Water Systems (RG-593)  (COMING SOON) a guide for preparing and reporting LCRR service line inventories.

Inventories must include the following:

  • All service lines (public and private) connected to the public water distribution system.
  • Categorization of each service line, or portion of the service line where ownership is split.

The four categories for service lines in the Inventory are:

  • “Lead” where the service line is made of lead.
  • “Galvanized Requiring Replacement” where a galvanized service line is or was at any time downstream of a lead service line or is currently downstream of a “Lead Status Unknown” service line. If the water system is unable to demonstrate that the galvanized service line was never downstream of a lead service line, it must presume there was an upstream lead service line.
  • “Non-lead” where the service line is determined through an evidence-based record, method, or technique not to be lead or galvanized requiring replacement. The water system may classify the actual material of the service line (i.e., plastic or copper) as an alternative to classifying it as “Non-lead.”
  • “Lead Status Unknown” where the service line material is not known to be lead, galvanized requiring replacement, or a non-lead service line, such as where there is no documented evidence supporting material classification.

Non-lead Service Line Inventory

CWSs and NTNCs that can certify that all service lines (public and private) connected to the public water distribution system are categorized as "Non-lead” must complete the Non-lead Service Line Inventory and Certification (TCEQ-20942). COMING SOON

Lead Service Line Inventory

CCWSs and NTNCs with service lines (public or private) connected to the public water distribution system that are categorized as “Lead,” “Galvanized Requiring Replacement,” or “Lead Status Unknown” must complete a comprehensive spreadsheet inventory based on system type.

  • Lead Service Line Inventory for CWSs (TCEQ-20943a) COMING SOON
  • Lead Service Line Inventory for NTNCs (TCEQ-20943b) COMING SOON

EPA has released their Guidance for Developing and Maintaining a Service Line Inventory and it is available at the EPA LCRR webpageExit the TCEQ

Schools and Child Care Programs

Community water systems that supply drinking water to schools or child care facilities will be required to comply with new LCRR requirements starting October 16, 2024.

School administrators or child care providers are not required to take action under the rule revisions at this time but can participate in voluntary lead sampling. See TCEQ’s Lead Testing in School and Child Care Program.
