Pesticide Registration Review; Draft Human Health and Ecological Risk Assessments for Certain Organophosphates; Extension of Comment Period
EPA issued a notice in the Federal Register of September 25, 2015, opening a comment period on draft human health and ecological risk assessments for certain organophosphate pesticides listed in the Table in this document, along with additional chemicals. This document extends the comment period by 45 days for just those chemicals listed in the Table in this document, i.e., from November 24, 2015 to January 8, 2016. This comment period is being extended in response to comments received by the Agency.
Pesticide Registration Review; Draft Human Health and Ecological Risk Assessments for Sulfonylureas; Notice of Availability and Request for Comment; Extension of Comment Period
EPA issued a notice in the Federal Register of September 25, 2015, concerning the publication of draft human health and ecological risk assessments for the registration review of 22 sulfonylurea chemicals and certain other non-sulfonylurea chemicals. This document extends the comment period for 30 days for only the chemicals listed in the Table in this document, from November 24, 2015 to December 24, 2015. The comment period is being extended in response to comments received by the Agency requesting additional time to review the sulfonylurea risk assessment documents.
Significant New Use Rules on Certain Chemical Substances; Withdrawal
EPA is withdrawing significant new use rules (SNURs) promulgated under the Toxic Substances Control Act (TSCA) for three chemical substances, which were the subject of premanufacture notices (PMNs). EPA published these SNURs using direct final rulemaking procedures, which requires EPA to take certain actions if a notice of intent to submit an adverse comment is received. EPA received notices of intent to submit adverse comments regarding the SNURs identified in this document. Therefore, the Agency is withdrawing the direct final rule SNURs identified in this document, as required under the direct final rulemaking procedures.
Treatment of Data Influenced by Exceptional Events
The Environmental Protection Agency (EPA) is proposing revisions to certain sections within the regulations that govern the exclusion of event-affected air quality data from regulatory decisions. The EPA is also providing a notice of availability of a draft version of the non-binding guidance document titled Draft Guidance on the Preparation of Exceptional Events Demonstrations for Wildfire Events that May Influence Ozone Concentrations.
National Emission Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial, and Institutional Boilers and Process Heaters
This action sets forth the Environmental Protection Agency's (EPA's) final decision on the issues for which it granted reconsideration on January 21, 2015, that pertain to certain aspects of the January 31, 2013, final amendments to the ``National Emission Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial, and Institutional Boilers and Process Heaters'' (Boiler MACT). The EPA is retaining a minimum carbon monoxide (CO) limit of 130 parts per million (ppm) and the particulate matter (PM) continuous parameter monitoring system (CPMS) requirements, consistent with the January 2013 final rule. The EPA is making minor changes to the proposed definitions of startup and shutdown and work practices during these periods, based on public comments received. Among other things, this final action addresses a number of technical corrections and clarifications of the rule. These corrections will clarify and improve the implementation of the January 2013 final Boiler MACT, but do not have any effect on the environmental, energy, or economic impacts associated with the proposed action. This action also includes our final decision to deny the requests for reconsideration with respect to all issues raised in the petitions for reconsideration of the final Boiler MACT for which we did not grant reconsideration.
Amitraz, Carfentrazone-ethyl, Ethephon, Malathion, Mancozeb, et al.; Tolerance Actions
EPA is revoking certain tolerances for the fungicides spiroxamine and triflumizole, the herbicides carfentrazone-ethyl and quizalofop ethyl; the insecticides amitraz, oxamyl, propetamphos, and spinosad; the plant growth regulators ethephon and mepiquat; and the tolerance on rice straw for multiple active ingredients. Also, EPA is modifying certain tolerances for the fungicides mancozeb, thiram, and triflumizole. In addition, EPA is establishing new tolerances for the fungicide mancozeb. Also, in accordance with current Agency practice, EPA is making minor revisions to the tolerance expressions for mepiquat and thiram. In addition, EPA is restoring the listings of tolerances on bulb onion and pear for methomyl residues to remedy inadvertent drafting errors and cover existing registrations. EPA is deferring a decision on the malathion tolerances at this time.
