Water: Total Coliform Rule

Total Coliform Rule Distribution System Advisory Committee (TCRDSAC)

Basic Information

EPA established the Total Coliform Rule Distribution System Advisory Committee (TCRDSAC) under the Federal Advisory Committee Act. The purpose of the TCRDSAC is to provide advice and make recommendations to the Agency on revisions to the Total Coliform Rule (TCR). The committee will also consider what information about distribution systems is needed to better understand the public health impact from the degradation of drinking water quality in distribution systems.

Agreement in Principle

On September 18, 2008, members of the Total Coliform Rule/Distribution System Advisory Committee (TCRDSAC) signed an Agreement in Principle (AIP) that recommends revisions to the 1989 Total Coliform Rule (TCR), as well research and information collection needed to better understand potential public health impacts from conditions in the distribution system.

Research and Information Collection Partnership (RICP or the Partnership)


The  TCRDSAC was also responsible for defining what information about distribution  systems is needed to better understand and address possible public health  impacts from potential degradation of drinking water quality in distribution  systems. After considering which  distribution system issues were important and assessing existing research and  data, the Advisory Committee recommended that a Research and Information  Collection Partnership (RICP) be formed.   The purpose and responsibilities of the RICP are found in Section 4.0 of  the TCRDSAC Agreement in Principle (AIP).

Consistent with the AIP, the partners with input from a Steering Committee have developed  the document titled, Priorities of the Distribution System Research and Information Collection Partnership.  The Priorities document identifies 10 high priority, science-driven, mutually-agreed-upon, strategically-focused, and decision-relevant research and information collection project area documents.  The project area documents are generally intended to identify groupings of similar needs rather than individual, stand alone projects.  It is possible that some of these documents may be more appropriate to divide into multiple projects to fully address the information needs described.

Cross Connection Control Resources

As part of the Agreement in Principle (September 2008), the Total  Coliform Rule Distribution System Advisory Committee recommended that “EPA and  primacy agencies reference and compile existing requirements, guidance, and  other information on cross connection control practices from EPA, states, AWWA  and other relevant parties with the aim of having a single, complete resource  library available to the public.”  EPA  has compiled the information below to meet that recommendation.
