| 2011-5799 | Approval and Promulgation of Implementation Plans; Oklahoma; Regional Haze State Implementation Plan; Federal Implementation Plan for Interstate Transport of Pollution Affecting Visibility and Best Available Retrofit Technology Determinations | Proposed Rule | EPA is proposing to partially approve and partially disapprove a revision to the Oklahoma State Implementation Plan (SIP) submitted by the State of Oklahoma through the Oklahoma Department of Environmental Quality (ODEQ) on February 19, 2010 that addresses regional haze for the first implementation period. This revision was submitted to address the requirements of the Clean Air Act (CAA or Act) and our rules that require states to prevent any future and remedy any existing man-made impairment of visibility in mandatory Class I areas caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the "regional haze program"). States are required to assure reasonable progress toward the national goal of achieving natural visibility conditions in Class I areas. EPA is proposing to approve a portion of this SIP revision as meeting certain requirements of the regional haze program and to partially approve and partially disapprove those portions addressing the requirements for best available retrofit technology (BART) and the long-term strategy (LTS). EPA is proposing a Federal Implementation Plan (FIP) to implement sulfur dioxide (SO<INF>2</INF>) emission limits on six sources to address these issues. EPA also is proposing to disapprove the State's submitted alternative to BART; EPA is taking no action on the submitted reasonable progress goals at this time. In addition, EPA is proposing to partially approve and partially disapprove a portion of a revision to the Oklahoma SIP submitted by the State of Oklahoma on May 10, 2007 and supplemented on December 10, 2007. We are taking action on that portion of the submittals addressing the requirements of CAA as it applies to visibility for the 1997 8-hour ozone and 1997 particulate matter (PM<INF>2.5</INF>) National Ambient Air Quality Standards (NAAQS). This portion of the submittals addresses the requirement that Oklahoma's SIP contain adequate provisions to prohibit emissions from interfering with measures required in another state to protect visibility. In this action, we propose a FIP to address the deficiencies in this portion of Oklahoma's SIP submittals. The proposed FIP will prevent emissions from six Oklahoma sources from interfering with other states' measures to protect visibility and to implement sulfur dioxide emission limits on these six sources to prevent such interference. | 2011-03-22 | 2011 | 3 | https://www.federalregister.gov/documents/2011/03/22/2011-5799/approval-and-promulgation-of-implementation-plans-oklahoma-regional-haze-state-implementation-plan | https://www.govinfo.gov/content/pkg/FR-2011-03-22/pdf/2011-5799.pdf | Environmental Protection Agency | 145 | EPA is proposing to partially approve and partially disapprove a revision to the Oklahoma State Implementation Plan (SIP) submitted by the State of Oklahoma through the Oklahoma Department of Environmental Quality (ODEQ) on February 19, 2010 that... |
