UNITED STATES ENVIRONMENTAL PROTECTION AGENCY WSG 145 Date Signed: October 3, 2001 Memorandum Subject: Final Implementation Guidance - Interim Enhanced Surface Water Treatment Rule and Stage 1 Disinfectants and Disinfection Byproducts Rule From: Cynthia C. Dougherty, Director (Signed by Evelyn Washington) Office of Ground Water and Drinking Water To: Drinking Water Program Managers Regions I - X I am writing to forward the final versions of the Implementation Guidance for the Interim Enhanced Surface Water Treatment Rule (IESWTR) and the Implementation Guidance for the Disinfectants and Disinfection Byproducts Rule (Stage 1 DBPR). The implementation guidances are being issued final without the state reporting guidance which will be forwarded shortly, as explained below. As part of the SDWIS/FED modernization effort, the draft reporting requirements for the Stage 1 DBPR and the IESWTR were reviewed and a lack of justification for some reporting requirements was identified. We feel it is very important to ensure that all critical information will be captured by SDWIS and that we do not pose an unnecessary burden by requesting that non-critical elements be reported, therefore we established a focus group with regional representatives from enforcement, implementation, data management, and rule development to identify the information needed to answer our business questions. The draft final reporting guidances are being developed based on the recommendations of the focus group and will be distributed this fall for one month of regional and stakeholder comment. I will forward the final reporting guidance as soon as possible following the close of the comment period. We hope you find the contents of the attached documents useful as we continue implementation of the rules. Along with summaries of each rule, each document contains guidance for preparing state primacy revision applications, sample monitoring forms, and a comprehensive list of frequently asked questions. All implementation guidances, technical guidances, disinfection profiling/CT calculation spreadsheet, quick reference guides and facts sheets are available on-line at www.epa.gov/safewater/mdbp/implement. We will continue to update the on-line version of frequently asked questions as necessary. To request additional hard copies of the documents, please contact the Safe Drinking Water Hotline at 1-800-426-4791. ------- WSG 145 Thank you for your participation in the guidance development process.
