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).

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.
