2040-AF15 201910 The Regulatory Plan and the Unified Agenda of Federal Regulatory and Deregulatory Actions 2040 Office of Water OW 2000 Environmental Protection Agency EPA National Primary Drinking Water Regulations for Lead and Copper: Regulatory Revisions

The current Lead and Copper Rule (LCR) reduces risks to drinking water consumers from lead and copper that can enter drinking water as a result of corrosion of plumbing materials. The LCR requires water systems to sample at taps in homes with leaded plumbing materials. Depending upon the sampling results, water systems must take actions to reduce exposure to lead and copper including corrosion control treatment, public education and lead service line replacement. The LCR was promulgated in 1991 and, overall, has been effective in reducing the levels of lead and copper in drinking water systems across the country. However, there are significant challenges in the implementation of the current rule, including the degree of flexibility and discretion it affords systems and primacy states with regard to optimization of corrosion control treatment; compliance sampling practices, which in some cases, may not adequately protect from lead exposure; and limited specific focus on key areas of concern such as schools. EPA intends to modernize and strengthen implementation of the LCR, strengthen its public health protections, and clarify its implementation requirements to make it more effective and more readily enforceable.

The Water Infrastructure Improvements for the Nation Act (2016) included amendments to the public notification provisions in section 1414 of the SDWA to address the need for public notification when a water system exceeds the lead action level. The manner, frequency, form, and content for giving notice under Section 1414 must be set forth by regulation. 42 U.S.C. Section 300g-3(c)(2).

Lead can cause serious health problems if too much enters the body from drinking water or other sources. It can cause damage to the brain and kidneys and can interfere with the production of red blood cells that carry oxygen to all parts of your body. The greatest risk of lead exposure is to infants, young children, and pregnant women. Scientists have linked the effects of lead on the brain with lowered IQ in children. Adults with kidney problems and high blood pressure can be affected by low levels of lead more than healthy adults. Lead is stored in the bones, and it can be released later in life. During pregnancy, the child receives lead from the mother's bones, which may affect brain development.
