Beginning in 2004, EPA conducted a wide-ranging review of implementation of the Lead and Copper Rule (LCR) to determine if there is a national problem related to elevated lead levels. EPA's comprehensive review consisted of several elements, including a series of workshops designed to solicit issues, comments, and suggestions from stakeholders on particular issues; a review of monitoring data to evaluate the effectiveness of the LCR; and a review of the LCR implementation by States and water utilities. As a result of this multi-part review, EPA identified seven targeted rule changes and EPA promulgated a set of short-term regulatory revisions and clarifications on October 10, 2007, to strengthen implementation of the existing Lead and Copper Rule. In developing the short-term revisions, EPA identified several regulatory changes to be considered as part of the more comprehensive changes to the rule. These considerations are longer-term in nature as they require additional data collection, research, analysis, and stakeholder involvement to support decisions. This action addresses the remaining regulatory revisions to be completed. Changes will be made to make the rule more cost effective and more protective of public health.
