| 97-28747 | National Primary Drinking Water Regulations: Interim Enhanced Surface Water Treatment Rule Notice of Data Availability | Proposed Rule | USEPA proposed in 1994 to amend the Surface Water Treatment Rule to provide additional protection against disease-causing organisms (pathogens) in drinking water (59 FR 38832: July 29, 1994). This Notice of Data Availability summarizes the 1994 proposal; describes new data and information that the Agency has obtained and analyses that have been developed since the proposal; provides information concerning recommendations of the Microbial-Disinfectants/Disinfection Byproducts (M-DBP) Advisory Committee (chartered in February 1997 under the Federal Advisory Committee Act) on key issues related to the proposal; and requests comment on these recommendations as well as on other regulatory implications that flow from the new data and information. USEPA solicits comment on all aspects of this Notice and the supporting record. The Agency also solicits additional data and information that may be relevant to the issues discussed in the Notice. USEPA is particularly interested in public comment on the Committee's recommendations and whether the Agency should reflect these recommendations in the final rule. In addition, USEPA is hereby providing notice that the Agency is re-opening the comment period for the 1994 proposal for 90 days beginning on the date of publication of today's Notice in the Federal Register. USEPA also requests that any information, data or views submitted to the Agency since the close of the comment period on the 1994 proposal that members of the public would like the Agency to consider as part of the final rule development process be resubmitted during this current 90-day comment period unless already in the underlying record in the Docket for this Notice. The Interim Enhanced Surface Water Treatment Rule (IESWTR) would apply to surface water systems serving 10,000 or more people. USEPA intends to promulgate the final rule in November 1998 as required by the 1996 Amendments to the Safe Drinking Water Act. The Agency plans subsequently to address surface water systems serving fewer than 10,000 people as part of a ``long-term'' Enhanced Surface Water Treatment Rule which may also include additional refinements for larger systems. Key issues related to the IESWTR that are addressed in this Notice include the establishment of a Maximum Contaminant Level Goal for Cryptosporidium; removal of Cryptosporidium by filtration; revised turbidity provisions; disinfection benchmark provisions to assure continued levels of microbial protection while facilities take the necessary steps to comply with new disinfection byproduct standards; sanitary surveys; inclusion of Cryptosporidium in the definition of ground water under the direct influence of surface water; and inclusion of Cryptosporidium in the watershed control requirements for unfiltered public water systems. Other issues that are discussed include inactivation of Cryptosporidium, viruses and Giardia lamblia; uncovered finished water reservoirs; cross connection control; and recycling of filter backwash water and filter-to-waste. Today's Federal Register also contains a related Notice of Data Availability for the Stage 1 Disinfectants/Disinfection Byproducts Rule (DBPR). USEPA proposed this rule at the same time as the IESWTR and plans to promulgate it along with the IESWTR in November 1998. | 1997-11-03 | 1997 | 11 | https://www.federalregister.gov/documents/1997/11/03/97-28747/national-primary-drinking-water-regulations-interim-enhanced-surface-water-treatment-rule-notice-of | https://www.govinfo.gov/content/pkg/FR-1997-11-03/pdf/97-28747.pdf | Environmental Protection Agency | 145 | USEPA proposed in 1994 to amend the Surface Water Treatment Rule to provide additional protection against disease-causing organisms (pathogens) in drinking water (59 FR 38832: July 29, 1994).
