Pyraclostrobin; Pesticide Tolerances
This regulation establishes tolerances for residues of pyraclostrobin in or on the herb subgroup 19A, dill seed, the stone fruit group 12–12, and the tree nut group 14–12, except pistachio. Interregional Research Project Number 4 (IR–4) requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).
Secondary (CINF13/INF-CINF17/INF) Alkane Sulfonates; Exemption From the Requirement of a Tolerance
This regulation establishes an exemption from the requirement of a tolerance for residues of two secondary alkane (C13- C17) sulfonates (CAS Reg. Nos. 85711–69–9 and 97489–15–1) when used as inert ingredients (surfactant) in pesticide formulations applied to growing crops at a maximum concentration not to exceed 40% by weight. Exponent, on behalf of Clariant Corporation, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of secondary alkane (C13-C17) sulfonates.
Approval and Promulgation of Air Quality Implementation Plans; Arizona; Regional Haze State and Federal Implementation Plans; Reconsideration
The Environmental Protection Agency (EPA) is approving a source-specific revision to the Arizona State Implementation Plan (SIP) that establishes an alternative to best available retrofit technology (BART) for Steam Units 2 and 3 (ST2 and ST3) at Arizona Electric Power Cooperative's (AEPCO) Apache Generating Station (Apache). Under the BART Alternative, ST2 will be converted from a primarily coal-fired unit to a unit that combusts pipeline-quality natural gas, while ST3 will remain as a coal-fired unit and would be retrofitted with selective non-catalytic reduction (SNCR) control technology. The SIP revision also revises the emission limit for nitrogen oxides (NOX) applicable to Apache Steam Unit 1 (ST1), when it is operated in combined-cycle mode with Gas Turbine 1 (GT1). EPA has determined that the BART Alternative for ST2 and ST3 would provide greater reasonable progress toward natural visibility conditions than BART, in accordance with the requirements of the Clean Air Act (CAA) and EPA's Regional Haze Rule (RHR). Accordingly, we are approving all elements of the SIP revision, with the exception of a provision pertaining to affirmative defenses for malfunctions. In conjunction with this final approval, we are withdrawing those portions of the Arizona Federal Implementation Plan (FIP) that address BART for Apache.
Approval and Promulgation of Air Quality Implementation Plans; District of Columbia, Maryland, and Virginia; Attainment Demonstration for the 1997 8-Hour Ozone National Ambient Air Quality Standard for the Washington, DC-MD-VA Moderate Nonattainment Area
The Environmental Protection Agency (EPA) is approving the attainment demonstration and associated contingency measures and motor vehicle emission budgets (MVEBs) for the Washington, DC-MD-VA, moderate ozone nonattainment area (Washington Area) for the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS) as submitted by the District of Columbia, the State of Maryland, and the Commonwealth of Virginia as revisions to each of their State Implementation Plans (SIPs). EPA has determined that each of the three SIP revisions including specifically the attainment demonstration, contingency measures and MVEBs meet the applicable requirements of the Clean Air Act (CAA or Act), and EPA is approving each revision.
EPAAR Clause for Level of Effort-Cost-Reimbursement Contract
The Environmental Protection Agency (EPA) amends the EPA Acquisition Regulation (EPAAR) to update policy, procedures, and contract clauses. The proposed rule updates the EPAAR clause Level of EffortCost-Reimbursement Term Contract, modifies the clause title, and updates the corresponding EPAAR clause prescription.
Protection of Stratospheric Ozone: Listing of Substitutes for Refrigeration and Air Conditioning and Revision of the Venting Prohibition for Certain Refrigerant Substitutes
Pursuant to the U.S. Environmental Protection Agency's (EPA) Significant New Alternatives Policy program, this action lists five flammable refrigerants as acceptable substitutes, subject to use conditions, in several end-uses: Household refrigerators and freezers, stand-alone retail food refrigeration equipment, very low temperature refrigeration, non-mechanical heat transfer, vending machines, and room air conditioning units. This action also exempts from Clean Air Act Section 608's prohibition on venting, release, or disposal the four hydrocarbon refrigerant substitutes listed in this action as acceptable, subject to use conditions, in specific end-uses. We are finalizing this exemption for those substitutes, subject to those use conditions and in those end-uses, on the basis of current evidence that their venting, release, or disposal does not pose a threat to the environment.
