Lead and Copper Rule Revisions (LCRR)
On December 16, 2021, EPA finalized the Lead and Copper Rule Revisions (LCRR), which further strengthen the protections against lead in drinking water. The LCRR has a number of new requirements for water systems. The department has created forms and guidance below to assist water systems with complying with the upcoming LCRR requirements.
Please be aware that water systems must continue to comply with the current LCR requirements until the LCRR goes into effect on October 16, 2024.
Technical assistance and hands-on support for service line inventory (SLI) and lead service line replacement planning (LSLRP) activities is available to systems serving populations up to 15,000 from the department’s dedicated SLI/LSLRP technical support contractors, WSP in partnership with Sunrise Engineering. Please see our answers to frequently asked questions. To request assistance, please complete a Service Agreement or email Colorado@LeadRemoval.info with questions.
Grants to support eligible water systems serving greater than or equal to (≥) 7,500 people with their service line inventory and lead service line replacement planning are available (Note: physical replacement of service lines is not an eligible expense). Systems must demonstrate an ability to proceed within 30 days of contract execution. Please see the Water Quality Grants webpage.
