EPA is required under the Toxic Substances Control Act (TSCA), as amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act, to make information publicly available and to publish information in the Federal Register pertaining to submissions under TSCA Section 5, including notice of receipt of a Premanufacture notice (PMN), Significant New Use Notice (SNUN) or Microbial Commercial Activity Notice (MCAN), including an amended notice or test information; an exemption application (Biotech exemption); an application for a test marketing exemption (TME), both pending and/or concluded; a notice of commencement (NOC) of manufacture (including import) for new chemical substances; and a periodic status report on new chemical substances that are currently under EPA review or have recently concluded review. This document covers the period from 09/01/ 2019 to 09/30/2019.

EPA has granted emergency exemptions under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) for use of pesticides as listed in this notice. The exemptions were granted during the period April 1, 2019 to September 30, 2019 to control unforeseen pest outbreaks.

Under the Federal Clean Air Act (CAA or Act), the Environmental Protection Agency (EPA) is proposing to approve elements of a State Implementation Plan (SIP) submission from the State of Oklahoma for the 2015 Ozone (O3) National Ambient Air Quality Standard (NAAQS). This submittal addresses how the existing SIP provides for implementation, maintenance, and enforcement of the 2015 O3 NAAQS (infrastructure SIP or i-SIP). The i-SIP ensures that the Oklahoma SIP is adequate to meet the state's responsibilities under the CAA for this NAAQS.

The Environmental Protection Agency (EPA) is finalizing approval of South Carolina's June 18, 2018, State Implementation Plan (SIP) submission pertaining to the ``good neighbor'' provision of the Clean Air Act (CAA or Act) for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS). The good neighbor provision requires each state's implementation plan to address the interstate transport of air pollution in amounts that contribute significantly to nonattainment, or interfere with maintenance, of a NAAQS in any other state. In this action, EPA is finalizing the determination that South Carolina's SIP contains adequate provisions to prohibit emissions within the State from contributing significantly to nonattainment or interfering with maintenance of the 2008 8-hour ozone NAAQS in any other state.
