Assessment Topic

As part of the 1996 amendments to the Safe Drinking Water Act, Congress required the USEPA to develop a Long Term Stage 1 Enhanced Surface Water Treatment Rule (LT1ESWTR) under Section 1412(b)(2)(C) which focuses on surface water drinking water systems that serve fewer than 10,000 persons. Congress also required EPA to develop a companion Filter Backwash Recycle Rule (FBRR) under Section 1412(b)(14) which will require that all surface water public water systems, regardless of size, meet new requirements governing the recycle of filter backwash within the drinking water treatment. Both of these rules supplement the existing 1989 Surface Water Treatment Rule (SWTR) which contains general microbrial filtration and disinfection as well as specific removal/inactivation provisions for Girardia, viruses, and bacteria for all surface water systems (including groundwater supplies under the direct influence (GWUDI) of surface water).
The goal of both the LT1ESWTR and the related FBRR is to provide additional protection from disease-causing microbial pathogens for community and non-community public water systems (PWSs) utilizing surface water. To ensure the goal is met, EPA is working with stakeholders to develop a joint proposal for both of these rules by September 1999 with final rule requirements promulgated by November 2000.

This document is being prepared in accordance with Small Business Regulatory Enforcement Fairness Act (SBREFA) which requires EPA to consider the impact its rules will have on small entities (in this case, community and non-community surface water systems that serve less than 10,000 people). EPA intends for this document to aide the SERs as they provide comment to EPA during the SBREFA process. Through this process EPA hopes to develop a rule that is cost-effective and minimizes potential economic impact on small entities while still providing the necessary public health protection.
