| 01-18093 | National Primary Drinking Water Regulations; Arsenic and Clarifications to Compliance and New Source Contaminants Monitoring | Proposed Rule | Today's action proposes and requests comment on a range of MCL options for the drinking water standard for arsenic. In particular, EPA is requesting comment on whether the data and technical analyses associated with the arsenic rule published in the January 22, 2001, Federal Register (66 FR 6976) as well as any new information that may be available would support setting the enforceable arsenic standard, or Maximum Contaminant Level (MCL), at 3 micrograms per liter (<greek-m>g/ L) (the feasible level), 5 <greek-m>g/L (the level proposed in June 2000), 10 <greek-m>g/L (the level published in the January 2001 rule), or 20 <greek-m>g/L. To assist commenters, today's document provides a brief summary of the principal data and technical analyses that accompanied the January 2001 arsenic rule and solicits comment on key issues associated with this information and analyses. In providing comment on these issues, commenters should focus on the preamble, technical support documents, and record associated with the January 2001 rule (not the June 2000 proposal (65 FR 38888)) because EPA made many changes to the analyses supporting the January decisions in response to public comment on the June 2000 proposal. In developing comments, commenters may also wish to consider information EPA plans to have in a notice in the fall of 2001, which will request comment on the results of the additional analyses of key scientific, technical and economic elements of the rule. The comment period for today's notice ends October 31, 2001, because the Agency expects this comment period to overlap with the fall 2001 notice's comment period on the scientific, cost, and benefits reviews. On May 22, 2001, EPA published in the Federal Register (66 FR 6976) a final rule delaying the effective date of the arsenic rule until February 22, 2002, in order to conduct reviews of the science and costing analyses. Additional information about these reviews as well as a review of the benefits analysis for the January 22, 2001, rule are provided in today's document. EPA expects the results of these reviews to be available within the comment period for today's proposal. This proposal does not affect the clarifications to compliance and new source contaminants monitoring regulations also issued on January 22, 2001, (66 FR 6976), for inorganic, volatile organic, and synthetic organic contaminants. Those regulations go into effect on January 22, 2004, as provided in the January 22, 2001, final rule. | 2001-07-19 | 2001 | 7 | https://www.federalregister.gov/documents/2001/07/19/01-18093/national-primary-drinking-water-regulations-arsenic-and-clarifications-to-compliance-and-new-source | https://www.govinfo.gov/content/pkg/FR-2001-07-19/pdf/01-18093.pdf | Environmental Protection Agency | 145 | Today's action proposes and requests comment on a range of MCL options for the drinking water standard for arsenic.
