The National Drinking Water Advisory Council (NDWAC) working group established to review potential revisions to the Lead and Copper Rule (LCR) held its first meeting on March 25 and 26. This initial meeting focused largely on providing background material to the workgroup members before moving into a more detailed discussion of corrosion control.
A good portion of the corrosion control discussion revolved around the premise of whether some form of “re-optimization” should be required for systems and what would trigger such a requirement. However, no strong consensus was reached on a recommended path forward due to the complexity of the issue. In particular, many workgroup members struggled with how much impact changes in corrosion control practices would have and the weight to give such potential changes in comparison to other issues yet to be discussed (and where bigger risk reduction potential is probable).
Follow-up meetings and conference calls will be scheduled throughout 2014 and early 2015 to address the other major components of the LCR, including sampling protocols, lead service line replacement and public education. EPA will publish Federal Register notices of all future meetings at least 15 days in advance of each meeting.
