Air Plan Approval; AK; Juneau's Mendenhall Valley Second 10-Year PM10
The Environmental Protection Agency (EPA) is proposing to approve the Juneau, Mendenhall Valley, Alaska (AK) limited maintenance plan (LMP) submitted on November 10, 2020, by the Alaska Department of Environmental Conservation (ADEC or ``the State''). This plan addresses the second 10-year maintenance period beyond redesignation for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM10). A LMP is used to meet Clean Air Act (CAA) requirements for formerly designated nonattainment areas that meet certain qualification criteria. The EPA is proposing to determine that Alaska's LMP meets CAA requirements. The plan relies upon control measures contained in the first 10-year maintenance plan and the determination that the Mendenhall Valley area currently monitors PM10 levels well below the PM10 National Ambient Air Quality Standards (NAAQS or ``the standard'').
Florasulam; Pesticide Tolerances
This regulation establishes a tolerance with regional registrations for residues of florasulam in or on grass, forage, fodder and hay, group 17. The Interregional Project Number 4 (IR-4) requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).
Air Plan Approval; OR; Updates to Adoption by Reference of Federal Provisions
The Environmental Protection Agency (EPA) is approving a revision to the Oregon State Implementation Plan (SIP) submitted on January 29, 2021. The revision updates the date by which Federal provisions are adopted by reference into the Oregon SIP, making air quality requirements more current.
Approval and Promulgation of Implementation Plans; New York; Ozone Season NOX
The Environmental Protection Agency (EPA) is approving a revision to the New York State Implementation Plan (SIP) as a SIP- strengthening measure that is expected to further control emissions of oxides of nitrogen (NOx) to contribute to attainment and maintenance of ozone standards. This SIP strengthening measure goes beyond what has already been approved as satisfying the RACT requirements for the 2008 ozone NAAQS. The EPA is approving a SIP revision of a New York regulation that lowers allowable NOx emissions from simple cycle and regenerative combustion turbines during the ozone season. The intended effect of this action is to approve control strategies that will reduce emissions and help New York State attain and maintain the national ambient air quality standards for ozone.
Air Plan Approval; Ohio; Infrastructure SIP Requirements for the 2015 Ozone NAAQS
The Environmental Protection Agency (EPA) is approving elements of a State Implementation Plan (SIP) submission from Ohio regarding the infrastructure requirements of section 110 of the Clean Air Act (CAA) for the 2015 Ozone National Ambient Air Quality Standards (NAAQS). The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA. EPA proposed to approve this action on March 9, 2021, and received no adverse comments.
Interstate Transport Prongs 1 and 2 for the 2010 Sulfur Dioxide (SO2
The Environmental Protection Agency (EPA) is taking final action to approve State Implementation Plan (SIP) submissions from Kansas and Nebraska addressing the Clean Air Act (CAA or Act) interstate transport SIP requirements for the 2010 Sulfur Dioxide (SO2) National Ambient Air Quality Standards (NAAQS). These submissions address the requirement that each SIP contain adequate provisions prohibiting air emissions that will have certain adverse air quality effects in other states. The EPA is approving portions of these infrastructure SIPs for the aforementioned states as containing adequate provisions to ensure that air emissions in the states will not significantly contribute to nonattainment or interfere with maintenance of the 2010 SO2 NAAQS in any other state.
