Environmental Protection Agency July 27, 2020 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) Region 5 is issuing a Notification of Intent to Delete the Scrap Processing Co., Inc. Superfund Site (Scrap Processing Site or Site) located in Medford, Wisconsin, 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 Wisconsin, through the Wisconsin Department of Natural Resources (WDNR), have determined that all appropriate response actions under CERCLA, other than operation and maintenance, monitoring institutional controls, and five-year reviews, have been completed at the Scrap Processing Site. However, this deletion does not preclude future actions under Superfund.

The Environmental Protection Agency (EPA) Region 4 is proposing to Delete 134-acres of the 140-acre Macalloy Corporation Superfund Site (Site) located at 1800 Pittsburgh Avenue, North Charleston, South Carolina 29405 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 South Carolina, through the South Carolina Department of Health and Environmental Control (SCDHEC), have determined that all appropriate response actions at these identified parcels under CERCLA, other than groundwater monitoring and five-year reviews, have been completed. However, this deletion does not preclude future actions under Superfund. This partial deletion pertains to 134-acres. The remaining 6-acres with groundwater concentrations above the 100 ug/L Maximum Contaminant Level (MCL) for total chromium will remain on the NPL and is not being considered for deletion as part of this action.

Pursuant to the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision submitted by the State of Maine. On February 18, 2020, the State submitted their 1997 ozone national ambient air quality standards (NAAQS) Limited Maintenance Plans (LMPs) for the Portland and Midcoast areas. EPA is proposing to approve the Portland and Midcoast LMPs because they provide for the maintenance of the 1997 ozone NAAQS through the end of the second 10-year portion of the maintenance period. The effect of this action will be to make certain commitments related to maintenance of the 1997 ozone NAAQS in the Portland and Midcoast maintenance areas part of the Maine SIP and therefore federally enforceable.

Under the Toxic Substances Control Act (TSCA), the Environmental Protection Agency (EPA) is finalizing amendments to the significant new use rule (SNUR) for long-chain perfluoroalkyl carboxylate (LCPFAC) chemical substances that were proposed on January 21, 2015; an amendment to a SNUR for perfluoroalkyl sulfonate chemical substances that was proposed on January 21, 2015; and an amendment to make inapplicable the exemption for persons who import a subset of LCPFAC chemical substances as part of surface coatings on articles, which was proposed on March 3, 2020. This final rule requires persons to notify EPA at least 90 days before commencing the manufacture (including import) or processing of these chemical substances for the significant new uses described in this notice. The required significant new use notification initiates EPA's evaluation of the conditions of use associated with the significant new use. Manufacturing (including import) or processing for the significant new use are prohibited from commencing until EPA has conducted a review of the notice, made an appropriate determination on the notice, and taken such actions as are required in association with that determination. As with any SNUR, this final rule excludes ongoing uses. Ongoing uses cannot be subject to a SNUR.
