Environmental Protection Agency May 8, 2019 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency Region 4 is issuing a Notice of Intent to Delete the Tennessee Products Superfund Site (Site) located in Chattanooga, Tennessee, from the National Priorities List (NPL) and requests public comments on this proposed action. The NPL, promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). The EPA and the State of Tennessee (State), through the Tennessee Department of Environment and Conservation (TDEC), have determined that all appropriate response actions under CERCLA, other than Five-Year Reviews, have been completed. However, this deletion does not preclude future actions under Superfund.

The Environmental Protection Agency (EPA) Region 8 is correcting the docket number for a notice of availability for comment that appeared in the Federal Register on April 18, 2019. The notice requested comments on the draft 2019 National Pollutant Discharge Elimination System (NPDES) drinking water general permit (DWGP) for wastewater discharges associated with drinking water treatment plants. The DWGP will authorize wastewater discharges from drinking water facilities located in Indian country in the EPA Region 8 in accordance with the terms and conditions described therein. This is the first issuance of the DWGP. EPA proposes to issue the permit for five (5) years and is seeking comment on the draft permit. The correct docket number appears in the heading and the DATES and ADDRESSES sections read correctly, below.

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 02/01/ 2019 to 02/28/2019.

The Environmental Protection Agency (EPA) is proposing to approve portions of a state implementation plan (SIP) submission from Maryland for the 2010 sulfur dioxide (SO2) National Ambient Air Quality Standard (NAAQS or standard). Whenever EPA promulgates a new or revised NAAQS, states are required to make a SIP submission showing how the existing approved SIP has all the provisions necessary to meet the requirements of the new or revised NAAQS, or to add any needed provisions necessary to meet the revised NAAQS. These SIP submissions are commonly referred to as ``infrastructure'' SIPs. The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the Clean Air Act (CAA). EPA is proposing to approve Maryland's submittal addressing certain infrastructure requirements for the 2010 SO2 NAAQS in accordance with the requirements of section 110 of the CAA, with the exception of the portion of the submittal pertaining to interstate transport.

The Environmental Protection Agency (EPA) is proposing the results of the residual risk and technology reviews (RTR) for the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Engine Test Cells/Stands. We found risks due to emissions of air toxics from this source category to be acceptable and determined that the current NESHAP provides an ample margin of safety to protect public health. We identified no new cost-effective controls under the technology review to achieve further emission reductions. We are proposing no revisions to the numerical emission limit based on the risk analysis and technology review. We are proposing to amend provisions addressing periods of startup, shutdown, and malfunction (SSM), to amend provisions regarding electronic reporting and to make clarifying and technical corrections.
