Final EPA-USGS Technical Report: Protecting Aquatic Life from Effects of Hydrologic Alteration
Document Number: 2016-30760
Type: Notice
Date: 2016-12-21
Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) and the United States Geological Survey are releasing a technical report: Final EPA- USGS Technical Report: Protecting Aquatic Life from Effects of Hydrologic Alteration. Healthy aquatic ecosystems provide an array of services to individuals and society, including clean drinking water, irrigation supplies, and recreational opportunities. Sound and sustainable management of aquatic ecosystems is an integral part of managing water resources to meet the needs of society. Hydrologic alteration can be a contributor to the impairment of water bodies that are designated to support aquatic life. Stresses on aquatic life associated with hydrologic alteration may be further exacerbated by climate change. This report provides States, Tribes and territories with scientific and technical information on the natural flow regime and potential effects of flow alteration on aquatic life, and a flexible, nonprescriptive framework that state water managers might consider if they are interested in developing narrative or numeric targets for flow regime components that are protective of aquatic life. The report also provides information about States and Tribes that have adopted narrative water quality standards to protect their waterbodies' flow regimes and on the potential impact of climate change on flow regimes.
Recent Postings of Broadly Applicable Alternative Test Methods

Type: Notice
Date: 2016-12-21
Agency: Environmental Protection Agency
This notice announces the broadly applicable alternative test method approval decisions the Environmental Protection Agency (EPA) has made under and in support of New Source Performance Standards (NSPS) and the National Emission Standards for Hazardous Air Pollutants (NESHAP) between January 1, 2016, and December 12, 2016.
Determination of Attainment of the 2008 Ozone National Ambient Air Quality Standards; Mariposa County, California
Document Number: 2016-30477
Type: Rule
Date: 2016-12-21
Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is taking direct final action to determine that the Mariposa County, California Moderate Nonattainment Area (NAA) has attained the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS or ``standards''). This determination is based on complete, quality-assured and certified data for 2013-2015. Preliminary data for 2016 are consistent with continued attainment of the standards in the Mariposa County NAA. This determination suspends any unfulfilled obligations to submit revisions to the state implementation plan (SIP) related to attainment of the 2008 ozone standards for the Mariposa County NAA for as long as the area continues to meet those standards.
Determination of Attainment of the 2008 Ozone National Ambient Air Quality Standards; Eastern San Luis Obispo, California
Document Number: 2016-30476
Type: Rule

Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is finalizing our determination that the San Luis Obispo (Eastern San Luis Obispo) ozone nonattainment area (NAA) in California has attained the 2008 ozone National Ambient Air Quality Standards (NAAQS or ``standards'') by the applicable attainment date of July 20, 2016. This determination is based on complete, quality-assured and certified data for the 3-year period preceding that attainment date. Based on this determination, the Eastern San Luis Obispo NAA will not be reclassified to a higher ozone classification.

Air Plan Approval; Ohio; Redesignation of the Columbus, Ohio Area to Attainment of the 2008 Ozone Standard
Document Number: 2016-30470
Type: Rule
Date: 2016-12-21
Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is finding that the Columbus, Ohio area is attaining the 2008 ozone National Ambient Air Quality Standard (NAAQS or standard) and redesignating the area to attainment for the 2008 ozone NAAQS because the area meets the statutory requirements for redesignation under the Clean Air Act (CAA or Act). The Columbus area includes Delaware, Fairfield, Knox, Licking, and Mason Counties. EPA is also approving, as a revision to the Ohio State Implementation Plan (SIP), the state's plan for maintaining the 2008 ozone standard through 2030 in the Columbus area. Finally, EPA finds adequate and is approving the state's 2020 and 2030 volatile organic compound (VOC) and oxides of nitrogen (NOX) Motor Vehicle Emission Budgets (MVEBs) for the Columbus area. The Ohio Environmental Protection Agency (Ohio EPA) submitted the SIP revision and redesignation request on June 16, 2016.
Air Plan Approval; MA; Infrastructure State Implementation Plan Requirements
Document Number: 2016-30466

Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is approving most elements of State Implementation Plan (SIP) submissions from Massachusetts regarding the infrastructure requirements of the Clean Air Act (CAA or Act) for the 1997 ozone, 2008 lead (Pb), 2008 ozone, 2010 nitrogen dioxide (NO2), and 2010 sulfur dioxide (SO2) National Ambient Air Quality Standards (NAAQS). EPA is also conditionally approving three aspects of the Commonwealth's submittals. In addition, we are also making findings of failure to submit pertaining to various aspects of the prevention of significant deterioration (PSD) requirements of infrastructure SIPs. Lastly, we are removing 40 CFR 52.1160 as legally obsolete. This action is being taken in accordance with the Clean Air Act.
Air Plan Approval; Tennessee; Regional Haze Progress Report
Document Number: 2016-30184
Type: Rule

Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Tennessee through the Tennessee Department of Environment and Conservation (TDEC) on April 19, 2013. Tennessee's April 19, 2013, SIP revision (Progress Report) addresses requirements of the Clean Air Act (CAA or Act) and EPA's rules that require each state to submit periodic reports describing progress towards reasonable progress goals (RPGs) established for regional haze and a determination of the adequacy of the State's existing SIP addressing regional haze (regional haze plan). EPA is approving Tennessee's Progress Report on the basis that it addresses the progress report and adequacy determination requirements for the first implementation period for regional haze.
Procedures for Rulemaking Under Section 6 of the Toxic Substances Control Act; Amendment
Document Number: 2016-30055
Type: Rule
Date: 2016-12-21
Agency: Environmental Protection Agency
Section 6 of the Toxic Substances Control Act (TSCA) provides EPA with several authorities for addressing risks from chemical substances and includes procedures that EPA must follow in doing so. EPA promulgated regulations shortly after TSCA was enacted to implement the procedural requirements for rulemaking under TSCA section 6 as they existed at that time. TSCA was recently amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act. This final rule removes the regulations specifying certain procedural requirements for rulemaking under TSCA section 6, including the requirement for a hearing, because TSCA, as amended, no longer mandates those procedures.
