Registration Review; Draft Malathion Human Health Risk Assessment; Extension of Comment Period
EPA issued a notice in the Federal Register of September 22, 2016 (81 FR 65355) (FRL-9952-53), opening a 60-day comment period for the draft malathion human health risk assessment. This document extends that comment period for 30 days. The new closing date will be December 21, 2016 rather than November 21, 2016. The comment period is being extended in response to a request from FMC Corporation citing the scope and complexity of the assessments, including the use of new models, risk assessment approaches, and science policy issues that require additional review time.
Notice of Receipt of Requests to Voluntarily Cancel Certain Pesticide Registrations and Amend Registrations To Terminate Certain Uses
In accordance with the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA is issuing a notice of receipt of requests by the registrants to voluntarily cancel their registrations and to amend product registrations to terminate uses. EPA intends to grant these requests at the close of the comment period for this announcement unless the Agency receives substantive comments within the comment period that would merit its further review of the requests, or unless the registrants withdraw its requests. If these requests are granted, any sale, distribution, or use of products listed in this notice will be permitted after the registrations have been cancelled and uses terminated only if such sale, distribution, or use is consistent with the terms as described in the final order.
Approval and Disapproval and Promulgation of Air Quality Implementation Plans; Interstate Transport for Wyoming
The Environmental Protection Agency (EPA) is proposing action on the portions of six submissions from the State of Wyoming that are intended to demonstrate that the State Implementation Plan (SIP) meets certain interstate transport requirements of the Clean Air Act (Act or CAA). These submissions address the 2006 and 2012 fine particulate matter (PM2.5) National Ambient Air Quality Standards (NAAQS), 2008 ozone NAAQS, 2008 lead (Pb) NAAQS, 2010 sulfur dioxide (SO2) NAAQS and 2010 nitrogen dioxide (NO2) NAAQS. The interstate transport requirements under the CAA consist of four elements: Significant contribution to nonattainment (prong 1) and interference with maintenance (prong 2) of the NAAQS in other states; and interference with measures required to be included in the plan for other states to prevent significant deterioration of air quality (prong 3) or to protect visibility (prong 4). Specifically, the EPA is proposing to approve interstate transport prongs 1 and 2 for the 2008 Pb and 2010 NO2 NAAQS, and proposing to approve prong 1 and disapprove prong 2 for the 2008 ozone NAAQS. The EPA is also proposing to approve interstate transport prong 4 for the 2008 Pb and 2010 SO2 NAAQS, and proposing to disapprove prong 4 for the 2006 PM2.5, 2008 ozone, 2010 NO2 and 2012 PM2.5 NAAQS.
Revisions to the Prevention of Significant Deterioration (PSD) and Title V Greenhouse Gas (GHG) Permitting Regulations and Establishment of a Significant Emissions Rate (SER) for GHG Emissions Under the PSD Program
On August 26, 2016, the Environmental Protection Agency (EPA) issued a proposed rule to revise provisions in the Prevention of Significant Deterioration (PSD) and title V permitting regulations applicable to greenhouse gases (GHGs) to fully conform with recent court decisions. The EPA is extending the comment period on this proposed rule that was scheduled to close on December 2, 2016. The EPA received a letter requesting the extension of the proposed rule public comment period to allow the public additional time to review the rule and supporting documentation.
Protection of Stratospheric Ozone: Update to the Refrigerant Management Requirements Under the Clean Air Act
The Clean Air Act prohibits the knowing release of ozone- depleting and substitute refrigerants during the course of maintaining, servicing, repairing, or disposing of appliances or industrial process refrigeration. The existing regulations require that persons maintaining, servicing, repairing, or disposing of air-conditioning and refrigeration equipment containing more than 50 pounds of refrigerant observe certain service practices that reduce emissions of ozone- depleting refrigerant. This rule updates those existing requirements as well as extends them, as appropriate, to non-ozone depleting substitute refrigerants, such as hydrofluorocarbons. Updates include strengthened leak repair requirements, recordkeeping requirements for the disposal of appliances containing more than five and less than 50 pounds of refrigerant, revisions to the technician certification program, and revisions for improved readability and compliance. As a result, this action reduces emissions of ozone-depleting substances and gases with high global warming potentials.
