Implementation of the 2015 National Ambient Air Quality Standards for Ozone: Nonattainment Area Classifications Approach
In this final rule, the EPA is establishing the air quality thresholds that define the classifications assigned to all nonattainment areas for the 2015 ozone national ambient air quality standards (NAAQS) (the ``2015 ozone NAAQS'') promulgated on October 1, 2015. This final rule also establishes the timing of attainment dates for each nonattainment area classification.
Pesticide Experimental Use Permit; Receipt of Application; Comment Request
This notice announces EPA's receipt of an application 93167- EUP-R from Oxitec Ltd. requesting an experimental use permit (EUP) for the OX513A Aedes aegypti mosquitoes expressing tetracycline Trans- Activator Variant (tTAV) protein. The Agency has determined that the permit may be of regional and national significance. Therefore, because of the potential significance, EPA is seeking comments on this application.
Certain New Chemicals or Significant New Uses; Statements of Findings for December 2017
Section 5(g) of the Toxic Substances Control Act (TSCA) requires EPA to publish in the Federal Register a statement of its findings after its review of TSCA section 5(a) notices when EPA makes a finding that a new chemical substance or significant new use is not likely to present an unreasonable risk of injury to health or the environment. Such statements apply to premanufacture notices (PMNs), microbial commercial activity notices (MCANs), and significant new use notices (SNUNs) submitted to EPA under TSCA section 5. This document presents statements of findings made by EPA on TSCA section 5(a) notices during the period from December 1, 2017 to December 31, 2017.
Notice of Proposed Withdrawal of the Control Techniques Guidelines for the Oil and Natural Gas Industry
The Environmental Protection Agency (EPA) is requesting public comment on a potential withdrawal of the Control Techniques Guidelines (CTG) for the Oil and Natural Gas Industry. The final CTG provided recommendations for reducing volatile organic compound (VOC) emissions from existing oil and natural gas industry emission sources in ozone nonattainment (NA) areas classified as Moderate or higher and states in the Ozone Transport Region (OTR). The CTG relied upon underlying data and conclusions made in the final rule titled ``Oil and Natural Gas Sector: Emission Standards for New, Reconstructed, and Modified Sources,'' published in the Federal Register on June 3, 2016 (2016 New Source Performance Standards (NSPS)). On June 5, 2017, the EPA granted reconsideration in regard to additional provisions of the 2016 NSPS. Pursuant to those actions, the EPA is currently looking broadly at the 2016 NSPS. In light of the fact that the EPA is reconsidering the 2016 NSPS and because the recommendations made in the CTG are fundamentally linked to the conclusions in the 2016 NSPS, the EPA believes it is prudent to withdraw the CTG in its entirety. The EPA also believes that the withdrawal will be more efficient for states in revising their state implementation plans (SIPs). The EPA is seeking comment on a potential withdrawal of the CTG.
Washington: Authorization of State Hazardous Waste Management Program Revisions
Washington applied to the Environmental Protection Agency (EPA) for final authorization of certain changes to its hazardous waste program under the Resource Conservation and Recovery Act, as amended, (RCRA). The EPA reviewed Washington's application, and has determined that these changes satisfy all requirements needed to qualify for final authorization. The EPA sought public comment under Docket number EPA- R10-RCRA-2017-0285 from July 13, 2017 to August 14, 2017 and from September 25, 2017 to October 25, 2017, prior to taking this final action to authorize these changes. The EPA received one comment which was responded to but was not applicable to this authorization action.
