Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Redesignation Requests and Maintenance Plans for Delaware County and Lebanon County 2012 Fine Particulate Matter Areas
The Environmental Protection Agency (EPA) is proposing to approve state implementation plan (SIP) revisions submitted by the Commonwealth of Pennsylvania. On January 23, 2019 and February 11, 2019, respectively, the Pennsylvania Department of Environmental Protection (PADEP) submitted requests for EPA to redesignate to attainment of the 2012 annual fine particulate matter (PM2.5) national ambient air quality standards (NAAQS) the Delaware County and Lebanon County nonattainment areas (the Delaware and Lebanon Areas or the Areas). EPA is proposing to grant PADEP's requests and to determine that the Delaware and Lebanon Areas meet the 2012 annual PM2.5 NAAQS, based on the most recent three years of certified air quality data. The effect of this proposed action, if finalized, would be to change the designation status of the Delaware and Lebanon Areas from nonattainment to attainment for the 2012 annual PM2.5 NAAQS, thereby removing the requirement for a nonattainment new source review (NNSR) permitting program and stopping the sanctions clock associated with a finding of failure to submit NNSR updates for the 2012 annual PM2.5 NAAQS. EPA is also proposing to approve PADEP's plans to ensure that the Delaware and Lebanon Areas continue to meet the 2012 PM2.5 NAAQS through 2030 (maintenance plans) as revisions to the Pennsylvania SIP. The maintenance plans for the Delaware and Lebanon Areas include 2014, 2022, and 2030 motor vehicle emissions budgets (MVEBs) for mobile sources of PM2.5 and nitrogen oxides (NOX). Finally, EPA is proposing to find these 2014, 2022, and 2030 MVEBs for PM2.5 and NOX adequate and to approve these MVEBs into the Pennsylvania SIP for transportation conformity purposes. This action is being taken under the Clean Air Act (CAA).
Approval of the Redesignation Request for the Washington, DC-MD-VA 2008 8-Hour Ozone National Ambient Air Quality Standard Nonattainment Area
The Environmental Protection Agency (EPA) is approving the request from the District of Columbia (the District) to redesignate to attainment their respective portion of the Washington, DC-MD-VA nonattainment area (hereafter ``the Washington Area'' or ``the Area'') for the 2008 8-hour ozone national ambient air quality standard (NAAQS or standard) (also referred to as the ``2008 ozone NAAQS'') as the District's portion of the Area meets the statutory requirements for redesignation under the Clean Air Act (CAA). EPA is therefore redesignating the District of Columbia to attainment for the 2008 ozone NAAQS in accordance with the CAA.
Certain New Chemicals or Significant New Uses; Statements of Findings for May 2019
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 May 1, 2019 to May 31, 2019.
Statutory Requirements for Substantiation of Confidential Business Information (CBI) Claims Under the Toxic Substances Control Act (TSCA)
On January 19, 2017, EPA announced an interpretation of section 14 of the Toxic Substances Control Act (TSCA). Under this interpretation, non-exempt confidential business information (CBI) claims must be substantiated at the time the information claimed as CBI is submitted to EPA, and non-exempt CBI claims submitted without a substantiation are considered deficient. To facilitate compliance with the change in interpretation, EPA announced it would undertake a non- statutorily required practice of sending a notice of deficiency to an affected business that submitted a non-exempt CBI claim without a substantiation, providing an opportunity to correct the deficiency. The Agency also sent out notices of deficiency in instances where there were other procedural flaws in the submission, namely where the required CBI certification statement was not provided, or no generic name was provided when specific chemical identity was claimed as CBI. EPA's extensive outreach on this interpretation over the past two years has been effective. As such, EPA is announcing it is revising its policy and that it will cease sending these non-statutorily required notices of deficiency to businesses who submit procedurally flawed CBI claims. This action makes more efficient EPA's implementation of the TSCA section 14(g) requirement to review within 90 days of receipt all CBI claims for chemical identity, with limited exceptions, as well as to review a representative subset of at least 25% of other non-exempt claims.
Certain New Chemicals or Significant New Uses; Statements of Findings for April 2019
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 April 1, 2019 to April 30, 2019.
Air Plan Approval; OR: 2018 Permitting Rule Revisions
The Environmental Protection Agency (EPA) proposes to approve revisions to the Oregon State Implementation Plan (SIP) submitted on December 11, 2018. The revisions update the SIP to allow for electronic public notice of proposed major stationary source permits, add references to stationary source sampling requirements, make use of plain language, and correct errors. The EPA reviewed the submitted revisions and proposes to find they are consistent with Clean Air Act requirements.
Outer Continental Shelf Air Regulations; Consistency Update for California
The Environmental Protection Agency (EPA) is finalizing the approval of a local rule and the update of the Outer Continental Shelf (OCS) Air Regulations proposed in the Federal Register on June 21, 2018. Requirements applying to OCS sources located within 25 miles of states' seaward boundaries must be updated periodically to remain consistent with the requirements of the corresponding onshore area (COA), as mandated by section 328(a)(1) of the Clean Air Act (``the Act''). The portion of the OCS air regulations that is being updated pertains to the requirements for OCS sources for which the Santa Barbara County Air Pollution Control District (``Santa Barbara County APCD'' or ``the District'') is the designated COA. The intended effect of approving the local rule and updating the OCS requirements for the Santa Barbara County APCD is to regulate emissions from OCS sources in accordance with the requirements onshore. The change to the existing requirements discussed in this document will be incorporated by reference into the Code of Federal Regulations and listed in the appendix to the OCS air regulations.
Air Plan Approval; NC; Emission Control Standards, Open Burning, and Miscellaneous Revisions
The Environmental Protection Agency (EPA) is taking final action to approve portions of a revision to the North Carolina State Implementation Plan (SIP) submitted by the State of North Carolina through the North Carolina Department of Environmental Quality (formerly the North Carolina Department of Environment and Natural Resources (NCDENR)), Division of Air Quality, on January 31, 2008. The revision includes changes to emission control standards and open burning regulations. The changes are part of North Carolina's strategy to meet and maintain the national ambient air quality standards (NAAQS). This action is being taken pursuant to the Clean Air Act (CAA or Act) and its implementing regulations.
