Notification of a Public Meeting of the Chartered Clean Air Scientific Advisory Committee (CASAC) and CASAC Secondary NAAQS Review Panel for Oxides of Nitrogen and Sulfur
The Environmental Protection Agency (EPA) Science Advisory Board (SAB) Staff Office announces a public meeting of the Chartered Clean Air Scientific Advisory Committee (CASAC) and CASAC Secondary NAAQS Review Panel for Oxides of Nitrogen and Sulfur to discuss their Draft Report on EPA's Integrated Science Assessment for Oxides of Nitrogen, Oxides of Sulfur, and Particulate MatterEcological Criteria (Second External Review DraftJune 2018).
TSCA Science Advisory Committee on Chemicals; Request for Nominations
The Environmental Protection Agency (EPA) invites the public to nominate scientific experts from a diverse range of disciplines to be considered for appointment to the Toxic Substances Control Act (TSCA), Science Advisory Committee on Chemicals (SACC). The purpose of the SACC is to provide independent advice and expert consultation, at the request of the EPA Administrator, with respect to the scientific and technical aspects of issues relating to implementation of TSCA. EPA anticipates appointing multiple SACC members over the next year. Sources in addition to this Federal Register Notice may be utilized to solicit nominations and identify candidates.
Trichloroethylene; TSCA Science Advisory Committee on Chemicals (SACC) Meeting; Amended Notice of Public Meeting
EPA is announcing that the March 24-26, 2020, Toxic Substances Control Act (TSCA) Science Advisory Committee on Chemicals (SACC) meeting, previously announced in the Federal Register on February 26, 2020, (85 FR 11079) (FRL-10005-52) is being changed to a virtual public meeting, with participation by phone and webcast only.

The Petition requested that the EPA object to a Clean Air Act (CAA) title V operating permit issued by the Texas Commission on Environmental Quality (TCEQ) to Dow Chemical Company (Dow) for its Dow Salt Dome Operations located in Brazoria County, Texas.
Approval and Promulgation of Air Quality Implementation Plans; North Dakota; Revisions to Permitting Rules
In accordance with section 110 of the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is proposing to approve State Implementation Plan (SIP) revisions submitted by North Dakota on May 2, 2019. The revisions contain amendments to the State's Ambient Air Quality Standards, Permit to Construct, and Prevention of Significant Deterioration (PSD) regulations.
Approval and Promulgation of Air Quality Implementation Plans; State of Montana; Columbia Falls, Kalispell and Libby PM10
The Environmental Protection Agency (EPA) is proposing to fully approve three Limited Maintenance Plans (LMPs), submitted by the State of Montana to the EPA on July 23, 2019, for the Columbia Falls, Kalispell and Libby Moderate nonattainment areas (NAAs) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM10) and concurrently redesignate the NAAs to attainment of the 24-hour PM10 National Ambient Air Quality Standard (NAAQS). In order to approve the LMPs and redesignations, the EPA is proposing to determine that the Kalispell and Libby NAAs have attained the 1987 24-hour PM10 NAAQS of 150 [micro]g/m\3\. This determination is based upon monitored air quality data for the PM10 NAAQS during the years 2016-2018. The EPA is also proposing to approve the Kalispell, Columbia Falls, and Libby LMPs as meeting the appropriate transportation conformity requirements.
Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Reasonably Available Control Technology (RACT) Determinations for Case-By-Case Sources Under the 1997 and 2008 8-Hour Ozone National Ambient Air Quality Standards
The Environmental Protection Agency (EPA) is proposing to approve multiple state implementation plan (SIP) revisions submitted by the Commonwealth of Pennsylvania. These revisions were submitted by the Pennsylvania Department of Environmental Protection (PADEP) to establish and require reasonably available control technology (RACT) for 26 major sources of volatile organic compounds (VOC) and nitrogen oxides (NOX) pursuant to the Commonwealth of Pennsylvania's conditionally approved RACT regulations. In this rulemaking action, EPA is only proposing to approve source-specific (also referred to as ``case-by-case'') RACT determinations for 19 of the 26 major sources submitted by PADEP. These RACT evaluations were submitted to meet RACT requirements for the 1997 and 2008 8-hour ozone national ambient air quality standards (NAAQS). This action is being taken under the Clean Air Act (CAA).
Air Plan Approval; West Virginia; Redesignation and Maintenance Plan for the West Virginia Portion of the Steubenville Sulfur Dioxide Nonattainment Area
In accordance with the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is proposing to redesignate the West Virginia portion of the Steubenville, Ohio-West Virginia multi-state sulfur dioxide (SO2) nonattainment area (referred to as the ``Steubenville Nonattainment Area'' or the ``Area'') from nonattainment to attainment. EPA is also proposing to approve West Virginia's maintenance plan for its portion of the Steubenville Nonattainment Area. Emissions of SO2 in the Area have been reduced and ambient SO2 readings in the nonattainment area are currently well below the 2010 1-hour SO2 national ambient air quality standard (NAAQS).
Significant New Use Rules on Certain Chemical Substances (19-1.B)
EPA is issuing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for the chemical substances identified in Unit IV. which were 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.
National Emission Standards for Hazardous Air Pollutants: Boat Manufacturing and Reinforced Plastic Composites Production Risk and Technology Review
This action finalizes the residual risk and technology reviews (RTR) conducted for the Boat Manufacturing and the Reinforced Plastic Composites Production source categories regulated under national emission standards for hazardous air pollutants (NESHAP). In addition, we are taking final action addressing emissions during periods of startup, shutdown, and malfunction (SSM) and amending provisions regarding electronic reporting of performance test and performance evaluation results and semiannual reports. These final amendments include removal of regulatory language that is inconsistent with the requirement that the standards apply at all times, inclusion of language requiring electronic reporting of performance test and performance evaluation results and semiannual reports, and an amendment to the Reinforced Plastic Composites Production NESHAP to clarify that mixers that route to a capture and control device system with at least 95-percent efficiency overall are not required to have covers. The numeric emission limits of the standards for both source categories remain unchanged.
