Agency Offers DBP Manuals to Small Water Systems

EPA has released new manuals to help small public water systems understand the Stage 2 Disinfectants and Disinfection Byproducts Rule (Stage 2 DBP) and Long Term 2 Enhanced Surface Water Treatment (LT2) rules.

In addition to providing an overview of the rules, the manuals provide step-by-step guidance on how small systems (those serving fewer than 10,000 people) can comply with the rule. The documents also provide helpful worksheets and examples of actions systems might take to comply. The documents serve as EPA's official compliance guide for small public water systems, as required by the Small Business Regulatory Enforcement Fairness Act (SBREFA) of 1996.

The Stage 2 DBP manual is available at The LT2 manual can be accessed at Both documents and other "Simple Tools for Effective Performance" are available on EPA's small water systems Web page at
