Environmental Protection Agency July 6, 2020 – Federal Register Recent Federal Regulation Documents

Pursuant to the provisions of the Federal Advisory Committee Act, notice is hereby given that the next meeting of the Children's Health Protection Advisory Committee (CHPAC) will be held virtually July 24 and 27, 2020. The CHPAC advises the Environmental Protection Agency (EPA) on science, regulations and other issues relating to children's environmental health.

This regulation establishes tolerances for residues of S- metolachlor in or on multiple commodities which are identified and discussed later in this document. The Interregional Project Number 4 (IR-4) and Syngenta Crop Protection, LLC requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).

The Environmental Protection Agency (EPA) is proposing to approve a SIP revision to the Jefferson County portion of the Kentucky State Implementation Plan (SIP), submitted by the Commonwealth of Kentucky (Commonwealth), through the Energy and Environment Cabinet (Cabinet) on September 5, 2019. The revision was submitted by the Cabinet on behalf of the Louisville Metro Air Pollution Control District (LMAPCD) and makes changes to the definition of ``volatile organic compound'' (VOC). EPA is proposing to approve the changes amending the definition of VOC because the Commonwealth has demonstrated that the changes are consistent with the Clean Air Act (CAA or Act).

The Environmental Protection Agency (EPA) is proposing to approve portions of the Kentucky infrastructure State Implementation Plan (SIP) submission for the 2015 8-hour ozone National Ambient Air Quality Standards (NAAQS) submitted to EPA on January 11, 2019. Whenever EPA promulgates a new or revised NAAQS, the Clean Air Act (CAA or Act) requires that states adopt and submit a SIP submission to establish that the state's implementation plan meets infrastructure requirements for the implementation, maintenance, and enforcement of each such NAAQS. Specifically, EPA is proposing to approve portions of the Kentucky infrastructure SIP submission that address the prevention of significant deterioration (PSD) and modeling requirements for the 2015 8-hour ozone NAAQS. EPA is proposing to approve these portions of the submission as they are consistent with the CAA.

This regulation establishes a temporary exemption from the requirement of a tolerance for residues of 1-aminocyclopropane-1- carboxylic acid (ACC) in or on apples and stone fruits when used in accordance with the terms of the Experimental Use Permit (EUP) under EPA Number 73049-EUP-12. Valent BioSciences, LLC., submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting a temporary exemption from the requirement of a tolerance for the use of ACC for a period of three years. This regulation eliminates the need to establish a maximum permissible level for residues of ACC resulting from use in accordance with the EUP No. 73049-EUP-12 under FFDCA. The temporary exemption from the requirement of a tolerance expires on July 6, 2023.

This action finalizes the residual risk and technology review (RTR) conducted for the Ethylene Production source category regulated under National Emission Standards for Hazardous Air Pollutants (NESHAP). In addition, the U.S. Environmental Protection Agency (EPA) is taking final action to correct and clarify regulatory provisions related to emissions during periods of startup, shutdown, and malfunction (SSM), including removing general exemptions for periods of SSM, adding work practice standards for periods of SSM where appropriate, and clarifying regulatory provisions for certain vent control bypasses. The EPA is also taking final action to revise requirements for heat exchange systems; add monitoring and operational requirements for flares; add provisions for electronic reporting of performance test results and other reports; and include other technical corrections to improve consistency and clarity. We estimate that these final amendments will reduce hazardous air pollutants (HAP) emissions from this source category by 29 tons per year (tpy) and reduce excess emissions of HAP from flares by an additional 1,430 tpy.
