Environmental Protection Agency December 16, 2014 – Federal Register Recent Federal Regulation Documents

In this action, the Environmental Protection Agency (EPA) proposes that it has completed its statutory obligation of the Clean Air Act to promulgate emissions standards for source categories accounting for not less than ninety percent of the aggregated emissions of each of the seven hazardous air pollutants enumerated in section 112(c)(6). This document explains the basis for the agency's conclusion that it completed this obligation in February of 2011, identifies the promulgated standards that collectively satisfy the obligation, and provides the public an opportunity to comment.

The Environmental Protection Agency (EPA) is approving the State of Maryland's request to redesignate to attainment the Maryland portion of the Martinsburg-Hagerstown, WV-MD Nonattainment Area (Martinsburg Area or Area) for the 1997 annual fine particulate matter (PM2.5) national ambient air quality standard (NAAQS). The Maryland portion of the Martinsburg Area is comprised of Washington County, Maryland. EPA has found that the Martinsburg Area attained the standard and continues to attain the standard. In addition, EPA is approving, as a revision to the Maryland State Implementation Plan (SIP), the Washington County maintenance plan to show maintenance of the 1997 annual PM2.5 NAAQS through 2025 for the Maryland portion of the Area. The maintenance plan includes the 2017 and 2025 PM2.5 and nitrogen oxides (NOX) mobile vehicle emissions budgets (MVEBs) for Washington County, Maryland for the 1997 annual PM2.5 NAAQS, which EPA is proposing to approve for transportation conformity purposes. These actions are being taken under the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the Feather River Air Quality Management District (FRAQMD) portion of the California State Implementation Plan (SIP). These revisions concern emissions of particulate matter (PM), volatile organic compounds (VOCs) and oxides of nitrogen (NOX) from wood heating devices and open burning. We are approving local rules that regulate these emission sources under the Clean Air Act (CAA or the Act).

The Environmental Protection Agency (EPA) is proposing to partially approve and partially disapprove a revision to the Texas State Implementation Plan (SIP) received from the State of Texas on March 31, 2009, that addresses regional haze for the first planning period from 2008 through 2018. This SIP revision was submitted to address the requirements of the Clean Air Act (CAA) and EPA's rules that require states to prevent any future, and remedy any existing, manmade impairment of visibility to assure reasonable progress toward the national goal of achieving natural visibility conditions in Class I areas. The EPA is proposing to partially approve this SIP revision as meeting certain requirements of the regional haze program, including the majority of the requirement to procure and install the Best Available Retrofit Technology (BART) at certain categories of existing major stationary sources built between 1962 and 1977. The EPA is also proposing to partially disapprove the SIP revision for not adequately addressing other requirements of the regional haze program related to reasonable progress, the long-term strategy, and the calculation of natural visibility conditions. The EPA is also proposing to disapprove SIP revisions submitted by Texas for the purpose of addressing the requirements of the CAA regarding interference with other states' programs for visibility protection for the 1997 fine particulate matter (PM2.5) National Ambient Air Quality Standards (NAAQS), the 1997 ozone NAAQS, the 2006 PM2.5 NAAQS, the 2008 ozone NAAQS, the 2010 Nitrogen Dioxide (NO2) NAAQS, and the 2010 Sulfur Dioxide (SO2) NAAQS. Finally, the EPA is proposing to partially disapprove a revision to the Oklahoma SIP submitted in February 19, 2010, that addresses regional haze for the first planning period. Specifically, EPA is proposing to disapprove Oklahoma's Reasonable Progress Goals (RPGs) for the Wichita Mountains Class I area. The EPA is proposing a Federal Implementation Plan (FIP) for each Texas and Oklahoma to remedy certain deficiencies in the SIP. The proposed FIP would implement SO2 emission limits on fifteen Texas sources as part of a long-term strategy for making reasonable progress at three Class I areas in Texas and Oklahoma, sets new RPGs for the Big Bend, the Guadalupe Mountains, and Wichita Mountains Class I areas, and substitutes Texas' reliance on the Clean Air Interstate Rule (CAIR) to satisfy BART requirements at its EGUs with reliance on CAIR's successor, the Cross-State Air Pollution Rule (CSAPR). Our proposed FIP for Oklahoma does not establish any additional requirements on sources within Oklahoma. The EPA is taking this action under the CAA. Comments must be received on or before February 17, 2015. Public Hearings. EPA is holding open housesfor the purpose of providing additional information and informal discussion for our proposal, and public hearingsto accept oral comments into the record, as follows:
