This extended comment period will afford greater opportunity to all interested parties to review and submit comments on the proposal.

Comments must be received on or before October 13, 2010.

# SUPPLEMENTARY INFORMATION:

                    The comment period for the proposed RTCR now ends on October 13, 2010. This is an extension of 30 days beyond the comment period established in the                     **Federal Register**                     on July 14, 2010. Anyone seeking to submit comments must follow the procedures specified in the                     **SUMMARY**                     section of the proposal as published in the                     **Federal Register**                     (75 FR 40926, July 14, 2010). The RTCR applies to all public water systems. The proposed revisions require systems that have an indication of coliform contamination in the distribution system to assess the problem and take corrective action that may reduce cases of illnesses and deaths due to potential fecal contamination and waterborne pathogen exposure. This proposal also establishes criteria for systems to qualify for and stay on reduced monitoring, thereby providing incentives for improved water system operation.                

                    See the proposal as published in the                     **Federal Register**                     (75 FR 40926, July 14, 2010) for additional information regarding public health concerns, proposed regulatory requirements, implementation schedules, estimated costs and benefits, implementation tools, and other issues.
