Revision of Certain Federal Water Quality Criteria Applicable to Washington (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Revision of Certain Federal Water Quality Criteria Applicable to Washington (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 On September 14, 2015, the Environmental Protection Agency (EPA) proposed revisions to the federal Clean Water Act (CWA) human health criteria applicable to waters under the State of Washington's jurisdiction to ensure that the criteria are set at levels that will adequately protect Washington residents, including tribes with treaty-reserved rights, from exposure to toxic pollutants. EPA promulgated Washington's previous criteria for the protection of human health in 1992 as part of the National Toxics Rule (NTR) (amended in 1999 for Polychlorinated Biphenyls (PCBs)), using the Agency's recommended criteria values at the time. EPA derived those previously applicable criteria using a fish consumption rate (FCR) of 6.5 grams per day (g/day) based on national surveys. The best available data now demonstrate that fish consumers in Washington consume much more fish than 6.5 g/day. There are also new data and scientific information available to update the toxicity and exposure parameters used to calculate human health criteria. On August 1, 2016, the State of Washington adopted and submitted human health criteria for certain pollutants, reflecting some of these new data and information. Concurrent with this final rule, EPA is taking action under CWA 303(c) to approve in part, and disapprove in part, the human health criteria submitted by Washington. For those criteria that EPA disapproved, EPA is finalizing federal human health criteria in this final rule. EPA is not finalizing criteria in this final rule for those state-adopted criteria that EPA approved, or for certain criteria that EPA has determined involve scientific uncertainty, as explained below.

Water Quality Standards (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Water Quality Standards (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA updates the federal water quality standards (WQS) regulation to provide a better-defined pathway for states and authorized tribes to improve water quality and protect high quality waters. The WQS regulation establishes a strong foundation for water quality management programs, including water quality assessments, impaired waters lists, and total maximum daily loads, as well as water quality-based effluent limits in National Pollutant Discharge Elimination System (NPDES) discharge permits. In this rule, EPA is revising six program areas to improve the WQS regulation's effectiveness, increase transparency, and enhance opportunities for meaningful public engagement at the state, tribal and local levels. Specifically, in this rule EPA: Clarifies what constitutes an Administrator's determination that new or revised WQS are necessary; refines how states and authorized tribes assign and revise designated uses for individual water bodies; revises the triennial review requirements to clarify the role of new or updated Clean Water Act (CWA) section 304(a) criteria recommendations in the development of WQS by states and authorized tribes, and applicable WQS that must be reviewed triennially; establishes stronger antidegradation requirements to enhance protection of high quality waters and promotes public transparency; adds new regulatory provisions to promote the appropriate use of WQS variances; and clarifies that a state or authorized tribe must adopt, and EPA must approve, a permit compliance schedule authorizing provision prior to authorizing the use of schedules of compliance for water quality-based effluent limits (WQBELs) in NPDES permits. In total, these revisions to the WQS regulation enable states and authorized tribes to more effectively address complex water quality challenges, protect existing water quality, and facilitate environmental improvements. The final rule also leads to better understanding and proper use of available CWA tools by promoting transparent and engaged public participation. This action finalizes the WQS regulation revisions initially proposed by EPA on September 4, 2013.

Section 304(a) (1) of the Clean Water Act 33 U.S.C. 1314(a) (1) requires the Environmental Protection Agency (EPA) to publish and periodically update ambient water quality criteria. These criteria are to accurately reflect the latest scientific knowledge (a) on the kind and extent of all identifiable effects on health and welfare including, but not limited to, plankton, fish shellfish, wildlife, plant life, shorelines, beaches, aesthetics, and recreation which may be expected from the presence of pollutants in any body of water including ground water; (b) on the concentration and dispersal of pollutants, or their byproducts, through biological, physical, and chemical processes; and (c) on the effects of pollutants on biological community diversity, productivity, and stability, including information on the factors affecting rates of eutrophication and organic and inorganic sedimentation for varying types of receiving waters. In a continuing effort to provide those who use EPA's water quality and human health criteria with up-to-date criteria values and associated information, the document was assembled. The document includes summaries of all the contaminants for which EPA has developed criteria recommendations.

Revisions to the Unregulated Contaminant Monitoring Regulation (UCMR 3) for Public Water Systems (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Revisions to the Unregulated Contaminant Monitoring Regulation (UCMR 3) for Public Water Systems (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 The 1996 amendments to the Safe Drinking Water Act (SDWA) require that the United States Environmental Protection Agency (EPA or the agency) establish criteria for a program to monitor unregulated contaminants and publish a list of up to 30 contaminants to be monitored every five years. This final rule meets the SDWA requirement by publishing the third Unregulated Contaminant Monitoring Regulation (i.e., UCMR 3), listing the unregulated contaminants to be monitored and addressing the requirements for such monitoring. This final rule describes analytical methods to monitor for 28 chemical contaminants and describes the monitoring for two viruses. UCMR 3 provides EPA and other interested parties with scientifically valid data on the occurrence of these contaminants in drinking water, permitting the assessment of the number of people potentially being exposed and the levels of that exposure. These data are one of the primary sources of occurrence and exposure information the agency uses to develop regulatory decisions for these contaminants. In addition, as part of an Expedited Methods Update, this rule finalizes amendatory language for a drinking water inorganic analysis table ("Inorganic chemical sampling and analytical requirements") in the Code of Federal Regulations (CFR). This minor editorial correction to the table does not affect the UCMR program.
