Notice of Availability of Proposed Modifications to NPDES General Permits for Stormwater Discharges From Small Municipal Separate Storm Sewer Systems in Massachusetts and New Hampshire
The Environmental Protection Agency (EPA) is providing this notice of availability (NOA) for proposed limited modifications to the final National Pollutant Discharge Elimination System (NPDES) general permits for discharges of stormwater from small Municipal Separate Storm Sewer Systems (MS4s) in Massachusetts and New Hampshire under the Clean Water Act (CWA). The proposed modifications represent the results of mediation supervised by the U.S. Court of Appeals for the District of Columbia Circuit Mediation Program between EPA and petitioners the National Association of Homebuilders (NAHB), the Home Builders and Remodelers Association of Massachusetts, Inc. (HBRAMA), the New Hampshire Home Builders Association (NHHBA), the Center for Regulatory Reasonableness (CRR), the Massachusetts Coalition for Water Resources Stewardship (MCWRS), the Town of Franklin, Massachusetts (Franklin), the City of Lowell, Massachusetts (Lowell), the Conservation Law Foundation (CLF), and the Charles River Watershed Association (CRWA). EPA and the petitioners have entered into settlement agreements that include commitments for EPA to propose certain modifications to the 2016 Massachusetts Small MS4 General Permit and the 2017 New Hampshire Small MS4 General Permit, and then to take final action on each proposal.
Draft Scopes of the Risk Evaluations To Be Conducted for Seven Chemical Substances Under the Toxic Substances Control Act; Notice of Availability
As required by the Toxic Substances Control Act (TSCA), which was amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act in June 2016, EPA is announcing the availability of the draft scope documents for the risk evaluations to be conducted for 7 of 20 High-Priority Substances designated in December 2019. The draft scope document for each chemical substance includes the conditions of use, hazards, exposures, and the potentially exposed or susceptible subpopulations the EPA plans to consider in conducting the risk evaluation for that chemical substance. EPA is also opening a 45- calendar day comment period on these draft scope documents to allow for the public to provide additional data or information that could be useful to the Agency in finalizing the scope of the risk evaluations; comments may be submitted to this docket and the individual dockets for each of the chemical substances.
Notification of Public Meetings of the Science Advisory Board; COVID-19 Review Panel
The Environmental Protection Agency (EPA) Science Advisory Board (SAB) Staff Office announces its intent to convene a panel of experts drawn from the Chartered Science Advisory Board, the SAB Chemical Assessment Advisory Committee (CAAC), and the SAB Drinking Water Committee (DWC) to provide rapid advice on scientific and technical issues related to the COVID-19 Pandemic and opportunities for current and future EPA research activities that might enhance and inform EPA's current and any future responses to SARS-CoV-2. The Staff Office announces two public meetings: (1) A teleconference of the SAB COVID-19 Review Panel to conduct a review of EPA's research activities in response to SARS CoV-2 and (2) a teleconference of the Chartered SAB to review the draft report of the SAB COVID-19 Review Panel.
Air Plan Approval; Pennsylvania; Attainment Plan for the Allegheny Pennsylvania Nonattainment Area for the 2010 Sulfur Dioxide Primary National Ambient Air Quality Standard
The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the Pennsylvania Department of Environmental Protection (PADEP) on behalf of the Allegheny County Health Department (ACHD). The SIP revision, submitted on October 3, 2017, provides for attainment of the 2010 sulfur dioxide (SO2) primary national ambient air quality standard (NAAQS) in the Allegheny Pennsylvania SO2 nonattainment area (hereafter referred to as the ``Allegheny Area'' or ``Area''). The SIP submission includes an attainment plan, including an attainment demonstration showing SO2 attainment in the Area, an analysis of reasonably available control technology (RACT) and reasonably available control measures (RACM) requirements, enforceable emission limitations and control measures, a reasonable further progress (RFP) plan, and contingency measures for the Allegheny Area. EPA is approving new SO2 emission limits and associated compliance parameters for the four major sources of SO2 in the Allegheny Area into the Allegheny County portion of the Pennsylvania SIP. Three of the sources (Clairton Coke Works, Edgar Thomson, and Irvin Works) are collectively known as the U.S. Steel (USS) Mon Valley Works, and the fourth is the Harsco Metals Facility, also referred to as Braddock Recovery. EPA is also approving the base year emissions inventory for the Allegheny Area and ACHD's certification that the nonattainment new source review (NNSR) permit program meets requirements. These revisions to the Pennsylvania SIP are in accordance with the requirements of the Clean Air Act (CAA).
Air Plan Approval; Texas; Construction Prior to Permit Amendment Issuance
Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing to approve a revision to the Texas (TX) State Implementation Plan (SIP) proposed January 29, 2020 and submitted for parallel processing by the State on January 30, 2020. The proposal amends certain air quality permitting rules located in Title 30 of the Texas Administrative Code (TAC), Section 116, Control of Air Pollution by Permits for New Construction or Modification. These revisions amend the State's New Source Review permitting regulations via the addition of new, proposed Section 116.118, Construction While Permit Application Pending. This proposed new section will allow applicants for certain permit amendments to begin construction after the executive director has completed a technical review and issued a draft permit including the permit amendment for public review and comment, i.e., prior to final permit issuance. Non-substantive, administrative-type, editorial changes, such as grammar, re-lettering, and reference revisions and/or corrections are also included in the revisions the EPA is proposing for approval.
Air Plan Approval; Illinois; Reasonable Further Progress Plan and Other Plan Elements for the Chicago Nonattainment Area for the 2008 Ozone Standard
The Environmental Protection Agency (EPA) is proposing to approve a revision to the Illinois State Implementation Plan (SIP) to meet the base year emissions inventory, reasonable further progress (RFP), RFP contingency measures, and motor vehicle inspection and maintenance (I/M) requirements of the Clean Air Act (CAA) for the Illinois portion of the Chicago-Naperville, Illinois-Indiana-Wisconsin area (Chicago area) for the 2008 ozone national ambient air quality standard (NAAQS or standard). EPA is also proposing to approve the 2017 transportation conformity motor vehicle emissions budgets (MVEBs) for the Illinois portion of the Chicago area for the 2008 ozone NAAQS. EPA is proposing to approve the state's submission as a SIP revision pursuant to section 110 and part D of the CAA and EPA's regulations because it satisfies the emissions inventory, RFP, RFP contingency measures, I/M, and transportation conformity requirements for areas classified as moderate nonattainment for the 2008 ozone NAAQS. Final approval of the Illinois SIP as meeting the I/M and RFP requirements of the CAA for the 2008 ozone NAAQS will permanently stop the Federal Implementation Plan (FIP) clocks for those specific elements, which were triggered by EPA's December 11, 2017 finding that Illinois failed to submit certain required SIP elements for the 2008 ozone NAAQS.
Significant New Use Rules on Certain Chemical Substances (19-2.B)
EPA is issuing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for chemical substances which are the subject of premanufacture notices (PMNs). This action requires persons to notify EPA least 90 days before commencing manufacture (defined by statute to include import) or processing of any of these chemical substances for an activity that is designated as a significant new use by this rule. The required notification initiates EPA's evaluation of the intended use within the applicable review period. Persons may not commence manufacture or processing for the significant new use until EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken such actions as are required as a result of that determination.
Light-Duty Vehicle Greenhouse Gas Program Technical Amendments
EPA is finalizing two technical corrections to the light-duty vehicle greenhouse gas (GHG) emissions standards regulations which were first promulgated in the 2012 rulemaking that established standards for model years 2017-2025 light-duty vehicles. First, EPA is correcting regulations pertaining to how auto manufacturers calculate credits for the GHG program's optional advanced technology incentives. This final rule corrects an error to ensure that auto manufacturers receive the appropriate amount of credits for electric vehicles, plug-in hybrid electric vehicles, fuel cell electric vehicles, and natural gas fueled vehicles. Second, this rule corrects an error in the regulations regarding how manufacturers must calculate certain types of off-cycle credits. Both of these corrections allow the program to be implemented as originally intended. The corrections are not expected to result in any additional regulatory burdens or costs.
