Strengthening Transparency in Regulatory Science; Extension of Comment Period and Notice of Public Hearing
On April 30, 2018, the Environmental Protection Agency (EPA) proposed a rule titled, ``Strengthening Transparency in Regulatory Science.'' The EPA is extending the comment period on the proposed rule, which was scheduled to close on May 30, 2018, until August 16, 2018. The EPA is also announcing a public hearing to be held for the proposed rule. The hearing will be held on July 17, 2018 in Washington, DC. The EPA is making these changes in response to public requests for an extension of the comment period and for a public hearing.
Air Plan Approval; Wisconsin; Particulate Matter Standard
The Environmental Protection Agency (EPA) is proposing to approve a January 4, 2018, request by the Wisconsin Department of Natural Resources (Wisconsin) to revise its state implementation plan (SIP) for fine particulate matter (PM2.5). Wisconsin updated its ambient air quality standards for PM2.5 to be consistent with EPA's 2012 revisions to the PM2.5 national ambient air quality standards (NAAQS). Wisconsin also revised its incorporation by reference rule to update references to the EPA monitoring methods.
Approval and Promulgation of Air Quality Implementation Plans; Wisconsin; VOC Definition Update and Removal of Obsolete Gasoline Vapor Recovery Regulations
EPA is proposing to approve a request submitted by the Wisconsin Department of Natural Resources (WDNR) on May 16, 2017, to revise the Wisconsin State Implementation Plan (SIP). The submission includes amendments to the Wisconsin Administrative Code updating the definition of ``volatile organic compound (VOC)'' to add eight compounds to the list of exempted compounds. These revisions are based on EPA rulemakings in 2012, 2013, and 2014, which added these compounds to the list of chemical compounds that are excluded from the Federal definition of VOC because, in their intended used, they make negligible contributions to tropospheric ozone formation. In addition, WDNR is also requesting to withdraw several previously approved provisions of the Wisconsin Administrative Code from the SIP concerning the State's Stage II vapor recovery (Stage II) program that terminated in 2012. EPA approved the removal of the Stage II program as a component of the Wisconsin SIP in 2013, including the approval of a demonstration under section 110(l) of the Clean Air Act (CAA) that addressed emissions impacts associated with the removal of the program.
Letter Peer Reviews for Exposure and Use Assessment and Human Health and Environmental Hazard Summary for Five PBT Chemicals; Notice of Public Preparatory Meeting and Public Comment Period
There will be a half-day preparatory meeting for experts selected to serve as letter peer reviewers for EPA's Exposure and Use Assessment and Human Health and Environmental Hazard Summary for Five PBT chemicals. The preparatory meeting will be held via teleconference and webcast only. Registration is required to attend.
Approval and Promulgation of Implementation Plans; Louisiana; 2008 8-Hour Ozone Maintenance Plan Revision for Baton Rouge
Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving a Louisiana State Implementation Plan (SIP) revision revising the 2008 8-hour ozone National Ambient Air Quality Standard (NAAQS) maintenance plan for the five-parish Baton Rouge area. The revised maintenance plan allows for relaxation of the Federal Reid Vapor Pressure (RVP) requirements in the Baton Rouge area. EPA has determined that relaxation of the RVP requirement would not interfere with attainment or maintenance of the NAAQS or with any other CAA requirement.
Air Plan Approval; Rhode Island; Enhanced Motor Vehicle Inspection and Maintenance Program
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Rhode Island. These revisions include regulations to update the enhanced motor vehicle inspection and maintenance (I/M) program in Rhode Island. The revised program includes a test and repair network consisting of on-board diagnostic (OBD2) testing for model year 1996 and newer vehicles and tailpipe exhaust test, using a dynamometer, for model year 1995 and older vehicles. The intended effect of this action is to approve the revised program into the Rhode Island SIP. This action is being taken in accordance with the Clean Air Act (CAA).
Air Plan Approval; Maine; Infrastructure Requirement for the 2010 Nitrogen Dioxide National Ambient Air Quality Standard
The Environmental Protection Agency (EPA) is proposing to approve a February 21, 2018, State Implementation Plan (SIP) revision submitted by the State of Maine. This revision addresses the interstate transport requirements of the Clean Air Act (CAA) with respect to the 2010 primary nitrogen dioxide (NO2) National Ambient Air Quality Standard (NAAQS). This action proposes to approve Maine's demonstration that the State is meeting its obligations regarding the interstate transport of NO2 emissions into other states. This action is being taken under the CAA.
Air Plan Approval; Connecticut; 1997 8-Hour Ozone Attainment Demonstration
The Environmental Protection Agency (EPA) is proposing action on the ozone attainment portion of a State Implementation Plan (SIP) revision submitted by the State of Connecticut to meet the Clean Air Act (CAA) requirements for attaining the 1997 8-hour ozone national ambient air quality standard (NAAQS). The EPA is proposing to approve Connecticut's demonstration of attainment of the 1997 8-hour ozone NAAQS for the New York-Northern New Jersey-Long Island, NY-NJ-CT moderate 1997 8-hour ozone nonattainment area (hereafter, the NY-NJ-CT area or the NY-NJ-CT nonattainment area). In addition, the EPA is proposing to approve Connecticut's reasonably available control measures (RACM) analysis. This action is being taken under the Clean Air Act.
Air Plan Approval; Wisconsin; Modification of Greenhouse Gases Language
The Environmental Protection Agency (EPA) is proposing to approve a revision to the Wisconsin State Implementation Plan (SIP) submitted by the Wisconsin Department of Natural Resources (WDNR) to EPA on November 28, 2017. In this revision, WDNR makes modifications to the language associated with how greenhouse gases are evaluated in the Prevention of Significant Deterioration (PSD) program. These revisions were made to reflect changes required by the United States Supreme Court in its June 23, 2014 decision, Utility Air Regulatory Group (UARG) v. EPA), 134 S. Ct. 2427.
