National Pollutant Discharge Elimination System (NPDES) 2021 Issuance of the Multi-Sector General Permit for Stormwater Discharges Associated With Industrial Activity
All 10 of the Environmental Protection Agency's (EPA) Regions are finalizing the 2021 National Pollutant Discharge Elimination System (NPDES) general permit for stormwater discharges associated with industrial activity, also referred to as the ``2021 Multi-Sector General Permit (MSGP)'' or the ``final permit.'' This final permit replaces EPA's administratively continued 2015 MSGP that expired on June 3, 2020. EPA is issuing this permit for five (5) years to provide permit coverage to eligible operators in all areas of the country where EPA is the NPDES permitting authority, including Idaho (until July 1, 2021), Massachusetts, New Hampshire, New Mexico, Indian country lands, Puerto Rico, the District of Columbia, and most U.S. territories and protectorates. This Federal Register document summarizes the final permit. EPA encourages the public to read the final permit and accompanying fact sheet to better understand the final permit. The final permit and fact sheet can be found at https://www.epa.gov/npdes/ stormwater-discharges-industrial-activities.
Chemical Category for Octahydro-Tetramethyl-Naphthalenyl-Ethanone (OTNE); Manufacturer Request for Risk Evaluation Under the Toxic Substances Control Act (TSCA); Notice of Availability and Request for Comments
The Environmental Protection Agency (EPA) is announcing the availability of and soliciting public comment on a manufacturer request for a risk evaluation under the Toxic Substances Control Act (TSCA) of ethanone, 1-(1,2,3,4,5,6,7,8-octahydro-2,3,5,5-tetramethyl-2- naphthalenyl), ethanone, 1-(1,2,3,4,5,6,7,8-octahydro-2,3,8,8- tetramethyl-2-naphthalenyl), ethanone, 1-(1,2,3,4,6,7,8,8a-octahydro- 2,3,8,8-tetramethyl-2-naphthalenyl), and ethanone, 1-(1,2,3,5,6,7,8,8a- octahydro-2,3,8,8-tetramethyl-2-naphthalenyl) (collectively, ``OTNE''). The request was made by International Flavors and Fragrances, Inc. (IFF), Privi Organics USA Corporation (Privi), and DRT America, Inc. (DRT) through the OTNE Consortium. EPA conducts risk evaluations to determine whether a chemical substance presents an unreasonable risk of injury to health or the environment without consideration of costs or other non-risk factors, including an unreasonable risk to potentially exposed or susceptible subpopulations, under the conditions of use. In the docket associated with this request is the manufacturer request for an EPA-conducted risk evaluation and possible additional conditions of use EPA has identified for inclusion within the scope of a risk evaluation of OTNE. EPA specifically invites public comment on the inclusion of any additional conditions of use and potentially exposed or susceptible subpopulations. The Agency is in the process of broadly re-examining how it intends to implement these and other provisions of amended TSCA including determining how new executive orders and other direction provided by the Biden-Harris Administration will be addressed. This process would benefit greatly from stakeholder feedback. After considering comments received in response to this solicitation, EPA will determine whether to grant or deny the manufacturer request. All TSCA risk evaluations, whether EPA-initiated or manufacturer-requested, will be conducted in the same manner.
Ozone Transport Commission Recommendation That EPA Require Daily Limits for Emissions of Nitrogen Oxides From Certain Sources in Pennsylvania: Extension of Comment Period
On January 15, 2021, EPA issued a Federal Register notice of public hearing and supplemental information regarding a recommendation submitted by the Ozone Transport Commission (OTC) to address ongoing ozone pollution in the northeastern United States. The OTC has recommended that EPA require Pennsylvania to revise its state implementation plan (SIP) to include additional control measures that would establish daily limits on emissions of nitrogen oxides (NOX) from coal-fired electricity generating units (EGUs) with already-installed selective catalytic reduction (SCR) or selective noncatalytic reduction (SNCR) controls. This document extends the comment period for 30 days, from March 8, 2021 to April 7, 2021.
Complex Polymeric Polyhydroxy Acids (CPPA); Amendment to the Exemption From the Requirement of a Tolerance
This regulation amends the existing tolerance exemption for residues of Complex Polymeric Polyhydroxy Acids (CPPA) in or on all food commodities as a plant growth regulator to add use as a nematicide in pesticide formulations. FBSciences, Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA) requesting this amendment. This regulation adds use as a nematicide to the existing tolerance exemption of CPPA under FFDCA.
Approval and Promulgation of Implementation Plans; United States Virgin Islands; Regional Haze Federal Implementation Plan; Correction
On October 22, 2012, the EPA published a final rule in the Federal Register promulgating a Federal Implementation Plan (FIP) intended to address regional haze obligations for the Territory of the United States Virgin Islands. However, at that time EPA erroneously failed to incorporate into the Code of Federal Regulations (CFR) certain emission limits that had been determined to be necessary to satisfy those obligations and that had been proposed and included in the docket for the action. EPA is proposing to correct this inadvertent error by incorporating the previously noticed limits into the CFR. EPA is not reopening any of its previous determinations here.
Air Plan Approval; OR; Smoke Management Revision
Environmental Protection Agency (EPA) is proposing to approve Oregon State Implementation Plan (SIP) revisions submitted on November 3, 2014 and September 27, 2019. The submitted revisions incorporate by reference the most recent updates to Oregon's Smoke Management Plan. EPA is acting only on the most recent version of such regulations as the previous versions are no longer in effect as a matter of state law. EPA is also making technical corrections related to previous approvals of components of Oregon's SIP. EPA is proposing to determine that the changes are consistent with Clean Air Act requirements.
Air Plan Approval; California; Placer County Air Pollution Control District; Open Burning Rules
The Environmental Protection Agency (EPA) is proposing to approve revisions to the Placer County Air Pollution Control District (PCAPCD) portion of the California State Implementation Plan (SIP). These revisions concern emissions of oxides of nitrogen (NOX) and particulate matter (PM) from open burning. We are proposing to approve local rules to regulate these emission sources under the Clean Air Act (CAA or the Act). We are taking comments on this proposal and plan to follow with a final action.
