Environmental Protection Agency January 21, 2021 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA or the Agency) is issuing a memorandum to provide guidance to the regulated community and permitting authorities on applying the recent decision of the United States Supreme Court in County of Maui v. Hawaii Wildlife Fund, 140 S. Ct. 1462 (2020), in the Clean Water Act Section 402 National Pollutant Discharge Elimination System (NPDES) permit program for point source discharges that travel through groundwater before reaching a water of the United States. Consistent with EPA Guidance; Administrative Procedures for Issuance and Public Petitions, published in the Federal Register on October 19, 2020, EPA solicited public comments on the draft guidance for thirty days, beginning on December 10, 2020. EPA has developed a responsiveness summary to address major concerns and comments, and it is available in the docket for this action. This guidance does not have the force and effect of law and it does not bind the public in any way. By issuing this guidance, the Agency intends only to provide clarity to the public regarding existing requirements under the law or Agency policies.

The Environmental Protection Agency (EPA) is announcing the availability of the final Toxic Substances Control Act (TSCA) risk evaluation of C.I. Pigment Violet 29. The purpose of conducting risk evaluations under TSCA is to determine whether a chemical substance presents an unreasonable risk of injury to health or the environment under the conditions of use, including an unreasonable risk to a relevant potentially exposed or susceptible subpopulation, without consideration of costs or other nonrisk factors. EPA has determined that specific conditions of use of C.I. Pigment Violet 29 present an unreasonable risk of injury to health or the environment. For those conditions of use for which EPA has found an unreasonable risk, EPA must move to address that unreasonable risk through risk management measures enumerated in TSCA. EPA has also determined that specific conditions of use do not present unreasonable risk of injury to health or the environment. For those conditions of use for which EPA has found no unreasonable risk to health or the environment, the Agency's determination is a final Agency action and is issued via order in the risk evaluation.
