Approval and Promulgation of Implementation Plans; Wisconsin; Nitrogen Oxide Combustion Turbine Alternative Control Requirements for the Milwaukee-Racine Former Nonattainment Area
On February 24, 2014, the Wisconsin Department of Natural Resources (WDNR) submitted revisions to the limits found in its nitrogen oxides (NOX) combustion turbine rule for the Milwaukee-Racine area formerly nonattainment for the 1997 ozone standard. This revision is contained in ``2013 Wisconsin Act 91Senate Bill 371,'' which provides for alternative NOX requirements, subject to Environmental Protection Agency (EPA) approval on a case-by- case basis, to determine whether these alternative limits satisfy the reasonably available control technology (RACT) requirements of the Clean Air Act (CAA). EPA proposed to approve this rule as a revision to the State Implementation Plan on April 30, 2014 and received adverse comments. EPA is issuing this supplemental proposal to revise and expand the basis for proposing approval of the SIP revision. This supplemental proposal addresses the issue of whether the SIP revision satisfies certain anti-backsliding requirements of the CAA. EPA is seeking comment only on the potential anti-backsliding issue, and is not re-opening for comment other issues raised in its prior proposal.
Approval and Promulgation of Implementation Plans; New Mexico; Regional Haze and Interstate Transport Affecting Visibility State Implementation Plan Revisions; Withdrawal of Federal Implementation Plan for the San Juan Generating Station
The Environmental Protection Agency (EPA) is taking final action to withdraw a Federal Implementation Plan (FIP) for New Mexico that became effective on September 21, 2011, that applies to the San Juan Generating Station (SJGS) in San Juan County, New Mexico, which is operated by the Public Service Company of New Mexico (PNM). We are removing the FIP requirements because we are taking final action today in a separate document in the Federal Register to approve revisions to the New Mexico State Implementation Plan (SIP), submitted by the New Mexico Environmental Department (NMED) to EPA, which address revised Best Available Retrofit Technology (BART) requirements for oxides of nitrogen (NOX) and the requirements of the Clean Air Act (CAA) concerning non-interference with programs in other states to protect visibility.
Approval and Promulgation of Implementation Plans; New Mexico; Regional Haze and Interstate Transport Affecting Visibility State Implementation Plan Revisions
The Environmental Protection Agency (EPA) is taking final action under the Clean Air Act (CAA) to approve a revision to the New Mexico Regional Haze State Implementation Plan (SIP) that addresses the Best Available Retrofit Technology (BART) requirement for oxides of nitrogen (NOX) for the Public Service Company of New Mexico (PNM) San Juan Generating Station (SJGS) in San Juan County, New Mexico. EPA is also taking final action under the CAA to approve a revision to the New Mexico Visibility Transport SIP that addresses the CAA requirement that emissions from sources in New Mexico do not interfere with programs in other states to protect visibility. The SIP meets this requirement through emission limitations for NOX and sulfur dioxide (SO2) at SJGS.
Automatic Delegation of Authority to the States of Colorado, Montana, North Dakota, South Dakota, Utah, and Wyoming To Implement and Enforce New Source Performance Standards
This action informs the public that on February 27, 2014, the EPA authorized automatic delegation to implement and enforce Clean Air Act New Source Performance Standards (NSPS) to the states of Colorado, Montana, North Dakota, South Dakota, Utah, and Wyoming (hereafter Region 8 states). Also in this action, we propose to delete the delegation status table of NSPS for Region 8 states in the Code of Federal Regulations at 40 CFR part 60.4(c) and replace it with a Web page address reflecting current delegation status of Region 8 states.
