Determination To Defer Sanctions; Arizona; Maricopa County; Reasonably Available Control Technology-Combustion Sources
The Environmental Protection Agency (EPA) is making an interim final determination that the Arizona Department of Environmental Quality (ADEQ) has submitted revised rules on behalf of the Maricopa County Air Quality Department (MCAQD or County) that correct deficiencies in its Clean Air Act (CAA or Act) state implementation plan (SIP) provisions concerning reasonably available control technology (RACT) ozone nonattainment requirements for controlling emissions of oxides of nitrogen (NOX) from combustion equipment and internal combustion engines. This determination is based on a proposed approval, published elsewhere in this Federal Register, of MCAQD's Rules 323 and 324 which regulate these source categories. The effect of this interim final determination is that the imposition of sanctions that were triggered by two prior disapprovals by the EPA, the first in 2020 for these two rules, and the second in 2021 for the County's 2017 determination that it was implementing RACT for major sources of NOX, are now deferred. If the EPA finalizes its approval of MCAQD's submission, relief from these sanctions will become permanent.
Air Plan Approval; Arizona; Maricopa County; Reasonably Available Control Technology-Combustion Sources
The Environmental Protection Agency (EPA) is proposing to approve a revision to the Maricopa County Air Quality Department's (MCAQD or County) portion of the Arizona State Implementation Plan (SIP). This revision concerns emissions of oxides of nitrogen (NOX) and particulate matter (PM) from combustion equipment and internal combustion (IC) engines. We are proposing to approve local rules to regulate these emission sources under the Clean Air Act (CAA or the Act) and to determine that the County's control measures implement Reasonably Available Control Technology (RACT) for major sources of NOX under the 2008 8-hour ozone National Ambient Air Quality Standard (NAAQS). We are taking comments on this proposal and plan to follow with a final action. Elsewhere in thi's Federal Register, we are making an interim final determination to defer CAA sanctions associated with our previous disapproval action concerning the County's RACT demonstration for major sources of NOX.
Pesticide Emergency Exemptions; Agency Decisions and State and Federal Agency Crisis Declarations
EPA has granted emergency exemptions under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) for use of pesticides as listed in this notice. The exemptions were granted during the period July 1, 2021, to June 30, 2022, to control unforeseen pest outbreaks.
IN-11693: Oxirane, 2-Methyl-, Polymer With Oxirane, di-(9Z)-9-Octadecenoate; Tolerance Exemption
This regulation establishes an exemption from the requirement of a tolerance for residues of oxirane, 2-methyl-, polymer with oxirane, di-(9Z)-9-octadecenoate (CAS Reg. No. 67167-17-3) average number molecular weight (in amu), 2500 when used as an inert ingredient in a pesticide chemical formulation. Ethox Chemicals, LLC, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of oxirane, 2-methyl-, polymer with oxirane, di-(9Z)-9- octadecenoate on food or feed commodities.
Air Plan Approval; California; Northern Sierra Air Quality Management District; Reasonably Available Control Technology
The Environmental Protection Agency (EPA) is taking final action to approve a revision to the Northern Sierra Air Quality Management District (NSAQMD or ``District'') portion of the California State Implementation Plan (SIP). This revision concerns NSAQMD's demonstration regarding reasonably available control technology (RACT) requirements and negative declarations for the 2015 8-hour ozone national ambient air quality standards (NAAQS or ``standards'') in the Western Nevada County ozone nonattainment area, which is under the jurisdiction of the District.
