Lead and Copper Rule Revisions (LCRR) (Renewal)

The National Primary Drinking Water Regulations (NPDWRs) for Lead and Copper (The Lead and Copper Rule or LCR), promulgated by the EPA in 1991, is a regulation promulgated under the Safe Drinking Water Act (SDWA). The LCRs goal is to reduce the levels of lead and copper in drinking water. The Lead and Copper Rule Revisions (LCRR) require community and non-transient non-community water systems to optimize corrosion control and, under specified conditions, install source water treatment, conduct public education, and/or replace lead service lines (LSLs) in the distribution system. The LCRR also expands public education requirements for lead, requires greater public access to information on lead, and further targets sensitive subpopulations by requiring additional lead in drinking water testing at schools and childcare facilities. This ICR estimates the incremental burden impacts of revisions to the LCR in terms of the burden and costs for the first three years after the final rule is published (estimated as 2020). It modifies the extension to the ICR entitled Disinfectants/Disinfection Byproducts, Chemical, and Radionuclides Rules (80 Federal Register 78224, December 16, 2015, Office of Management and Budget (OMB) control number 2040-0204), which expires on March 31, 2023 and estimates the burden and costs associated with the previous LCR, as well as other rules, (the 2015 ICR).The Long-Term Revisions are intended to strengthen the implementation of the LCR in the areas of CCT, customer awareness, and LSLR. The changes are expected to ensure and enhance the protection of public health through the reduction in lead exposure in drinking water. The AL and maximum contaminant level goals (MCLGs) have not changed in the LCRR. A new lead TL, however, has been added.
