Air Plan Approval; Florida; Infrastructure Requirements for the 2015 8-Hour Ozone National Ambient Air Quality Standard
The Environmental Protection Agency (EPA) is proposing to approve the State Implementation Plan (SIP) submission provided by the State of Florida, through the Florida Department of Environmental Protection (FDEP), through a letter dated September 18, 2018, for inclusion into the Florida SIP. This proposal pertains to the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2015 8-hour ozone national ambient air quality standards (NAAQS). Whenever EPA promulgates a new or revised NAAQS, the CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA. FDEP certified that the Florida SIP contains provisions that ensure the 2015 8-hour ozone NAAQS is implemented, enforced, and maintained in Florida. EPA is proposing to determine that Florida's SIP submission satisfies certain required infrastructure elements for the 2015 8-hour ozone NAAQS.
Proposed Consent Decree; Clean Air Act Citizen Suit
In accordance with section 113(g) of the Clean Air Act, as amended (``CAA'' or the ``Act''), notice is given of a proposed consent decree in Center for Biological Diversity, et al., v. Wheeler, No. 4:19-cv-01544 (N.D. Cal.). On June 26, 2019, the Center for Biological Diversity and Center for Environmental Health filed a complaint in the United States District Court for the Northern District of California alleging that the Administrator of the United States Environmental Protection Agency (``EPA'') failed to perform non-discretionary duties to make a determination whether the West Central Pinal nonattainment area attained the 2006 24-hour fine particulate matter (``PM2.5'') national ambient air quality standard (``NAAQS'') by the attainment date and to take final action to promulgate a federal implementation plan (``FIP'') addressing certain deficiencies in the State of Arizona's new source review program. The EPA has already taken final action to find that the West Central Pinal nonattainment area attained the NAAQS. Thus, the proposed consent decree would establish deadlines for EPA to take specified actions as to the remaining claim.
Public Water System Supervision Program Revision for the State of Tennessee
Notice is hereby given that the State of Tennessee is revising its approved Public Water System Supervision Program. Tennessee has adopted drinking water regulations for the Revised Total Coliform Rule. The Environmental Protection Agency (EPA) has determined that Tennessee's regulations are no less stringent than the federal rule and the revision otherwise meets applicable Safe Drinking Water Act requirements. Therefore, EPA intends to approve this revision to the State of Tennessee's Public Water System Supervision Program.
National Emission Standards for Hazardous Air Pollutants: Miscellaneous Organic Chemical Manufacturing Residual Risk and Technology Review
On December 17, 2019, the U.S. Environmental Protection Agency (EPA) published the proposed rulemaking concerning the residual risk and technology review (RTR) for the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Miscellaneous Organic Chemical Manufacturing source category. The EPA also requested public comment on the proposed action. The EPA is announcing that it will hold two public hearings to provide interested parties the opportunity to present data, views, or arguments concerning the proposed action.
National Emission Standards for Hazardous Air Pollutants: Miscellaneous Organic Chemical Manufacturing Residual Risk and Technology Review
The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Miscellaneous Organic Chemical Manufacturing source category. The EPA is proposing decisions concerning the residual risk and technology review (RTR), including proposing amendments pursuant to the technology review for equipment leaks and heat exchange systems, and also proposing amendments pursuant to the risk review to specifically address ethylene oxide emissions from storage tanks, process vents, and equipment leaks. The EPA is also proposing amendments to correct and clarify regulatory provisions related to emissions during periods of startup, shutdown, and malfunction (SSM), including removing general exemptions for periods of SSM, adding work practice standards for periods of SSM where appropriate, and clarifying regulatory provisions for certain vent control bypasses. Lastly, the EPA is proposing to add monitoring and operational requirements for flares that control ethylene oxide emissions and flares used to control emissions from processes that produce olefins and polyolefins; and add provisions for electronic reporting of performance test results and reports, performance evaluation reports, and compliance reports. We estimate that, if finalized, these proposed amendments (not including the potential excess emission reductions from flares) would reduce hazardous air pollutants (HAP) emissions from this source category by 116 tons per year (tpy) and would reduce ethylene oxide emissions from this source category by approximately 10 tpy.
