Air Plan Disapproval; Texas; Control of Air Pollution From Visible Emissions and Particulate Matter
Pursuant to the Federal Clean Air Act (CAA, the Act), the Environmental Protection Agency (EPA) is proposing to disapprove a revision to the Texas State Implementation Plan (SIP) submitted by the State of Texas through the Texas Commission on Environmental Quality (TCEQ) on August 20, 2020. The SIP submittal addresses emissions during planned Maintenance, Startup and Shutdown (MSS) activities for certain Electric Generating Units (EGUs) and includes requirements intended to address visible emissions (opacity) and Particulate Matter (PM) emissions during planned MSS activities The requirements are included in eight Agreed Orders (AOs) issued by TCEQ to the affected EGUs and provided in the SIP revision. EPA is proposing to determine that the requirements contained in these AOs do not meet the CAA requirements that emission limitations must be practically enforceable and must apply on a continuous basis. We are taking this action in accordance with section 110 of the Act.
Determination of Attainment by the Attainment Date for the 2010 1-Hour Primary Sulfur Dioxide National Ambient Air Quality Standard; Texas; Freestone-Anderson and Titus Counties
Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing to determine that the sulfur dioxide (SO2) nonattainment area (NAA) in Freestone and Anderson Counties and the SO2 NAA in Titus County have each attained the 2010 1-hour primary SO2 national ambient air quality standard (NAAQS) by the applicable attainment date of January 12, 2022. This determination is based on primary source shutdowns, available ambient air quality monitoring data from the 2019-2021 monitoring period, relevant modeling analysis, and additional emissions inventory information. This action, if finalized, will address the EPA's obligation under CAA section 179(c) to determine whether the Freestone-Anderson and Titus SO2 NAAs attained the 2010 1-hour primary SO2 NAAQS by the statutory attainment date of January 12, 2022, for each area.

The Environmental Protection Agency (EPA) is approving the removal of the New Jersey Clean Air Interstate Rule (CAIR) nitrogen oxides (NOX) Trading Program regulations from the New Jersey State Implementation Plan (SIP) and is conditionally approving the removal of the New Jersey NOX Budget Program regulations from the New Jersey SIP. On August 23, 2018, the New Jersey Department of Environmental Protection (NJDEP) submitted a SIP revision requesting the removal of the State's CAIR NOX Trading Program and NOX Budget Program regulations from the New Jersey SIP. NJDEP submitted a supplement to the revision on May 31, 2024, that commits NJDEP to develop a Memorandum of Agreement with the EPA that indicates how the State of New Jersey will maintain compliance with the State's NOX SIP Call obligations for the types of large non- electricity generating units (non-EGUs) that were previously regulated under the New Jersey NOX Budget Program.
Di-isononyl phthalate (DINP); Draft Risk Evaluation Under the Toxic Substances Control Act (TSCA); Notice of Availability, Webinar and Request for Comment
The Environmental Protection Agency (EPA or Agency) is announcing the availability of and seeking public comment on a draft risk evaluation under the Toxic Substances Control Act (TSCA) for di- isononyl phthalate (DINP) (1,2-Benzene- dicarboxylic acid, 1,2- diisononyl ester) (CASRN 28553-12-0). The purpose of risk evaluations under TSCA is to determine whether a chemical substance presents an unreasonable risk of injury to health or the environment, without consideration of costs or non-risk factors, including unreasonable risk to potentially exposed or susceptible subpopulations identified as relevant to the risk evaluation by EPA, under the conditions of use (COU). EPA has used the best available science to prepare this draft risk evaluation and to preliminarily determine that DINP poses unreasonable risk to human health.
