EPA announced in the July 14 Federal Register a proposed rule revising the 1989 Total Coliform Rule. The proposed Revised Total Coliform Rule (TCR) is designed to offer meaningful opportunity for greater public health protection beyond the current Total Coliform Rule. 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 updates provisions in other rules that reference analytical methods and other requirements in the current TCR (e.g., Public Notification and Ground Water Rules). These proposed revisions are in accordance with the Safe Drinking Water Act as amended, which requires EPA to review and revise, as appropriate, each national primary drinking water regulation promulgated under the Safe Drinking Water Act not less often than every six years. As with the current Total Coliform Rule, the proposed Revised Total Coliform Rule applies to all public water systems. Comments must be received on or before September 13, 2010.
