Receipt of Several Pesticide Petitions Filed for Residues of Pesticide Chemicals in or on Various Commodities
This document announces the Agency's receipt of several initial filings of pesticide petitions requesting the establishment or modification of regulations for residues of pesticide chemicals in or on various commodities.
Pyridate; Receipt of Applications for Emergency Exemption, Solicitation of Public Comment
EPA has received specific exemption requests from the Montana and the North Dakota Departments of Agriculture to use the herbicide pyridate (CAS No. 55512-33-9) on chickpea to control kochia, including glyphosate-resistant kochia. The applicants propose a use of a pesticide that was voluntarily canceled in 2004, and which is now considered to be unregistered under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). EPA is soliciting public comment before making the decision whether or not to grant the exemptions.
Limited Disapproval of Air Plan Revisions; Arizona; New Source Review; PM2.5
The Environmental Protection Agency (EPA) is finalizing a limited disapproval of a revision to the Arizona Department of Environmental Quality (ADEQ) portion of the Arizona State Implementation Plan (SIP) under the Clean Air Act (CAA or Act). This ADEQ-submitted SIP revision primarily was intended to serve as a replacement of ADEQ's SIP-approved rules for the issuance of New Source Review (NSR) permits for stationary sources, including but not limited to the rules governing the review and permitting of major sources and major modifications under the Act. This action concerns only the major nonattainment NSR provisions in ADEQ's submittal as they pertain to the Nogales and West Central Pinal nonattainment areas for particulate matter with a diameter of 2.5 micrometers or less (PM2.5). The EPA previously finalized a limited approval for these PM2.5 nonattainment areas related to certain major nonattainment NSR permitting requirements for PM2.5 under the CAA. We subsequently proposed a limited disapproval for these PM2.5 nonattainment areas to set the stage for remedying certain deficiencies related to these nonattainment NSR permitting requirements for PM2.5, and this action finalizes this limited disapproval.
