| Title: National Primary Drinking Water Regulations: Revisions to the Total Coliform Rule | |
| Abstract: EPA is revising the Total Coliform Rule (TCR), which was published in 1989. On July 18, 2003, EPA published a Federal Register (68 FR 42907) Notice of Intent to revise the TCR. EPA intends revisions to the TCR to maintain or provide for greater human health protection than under the existing TCR while improving system efficiency. A Federal Advisory Committee recommended that EPA, as part of the TCR 6-year review process, "initiate a process for addressing cross-connection control and backflow prevention requirements and consider additional distribution system requirements related to significant health risks."The original TCR, promulgated in 1989, protects human health by requiring microbial monitoring in drinking water distribution systems. The TCR does not include distribution system corrective or protective requirements to reduce contamination from coliforms and other contaminants. Since then, EPA has gained a better understanding of distribution system impacts on human health and, therefore, intends to strengthen the TCR and to consider how to address distribution system contamination issues. The process to do so involves a performance evaluation, development of issue papers on both distribution systems and total coliform, stakeholders meetings, and proposed and final rules. EPA has also convened a Federal Advisory Committee to address the TCR revisions and to consider distribution system issues. In September 2008, members of the Federal Advisory Committee signed an agreement in principle (AIP), which recommended revisions to the TCR, as well as research and information collection needed to better understand potential public health impacts from conditions in the distribution system and control of microbial drinking water contamination. | |
