Environmental Protection Agency August 12, 2010 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) proposes to approve the Gila River Indian Community's (GRIC or the Tribe) Tribal Implementation Plan (TIP) under the Clean Air Act (CAA) to regulate air pollution within the exterior boundaries of the Tribe's reservation. The proposed TIP is one of four CAA regulatory programs that comprise the Tribe's Air Quality Management Plan (AQMP). EPA approved the Tribe for treatment in the same manner as a State (Treatment as State or TAS) for purposes of administering the AQMP and other CAA authorities on October 21, 2009. In this action we propose to act only on those portions of the AQMP that constitute a TIP containing severable elements of an implementation plan under CAA section 110(a). The proposed TIP includes general and emergency authorities, ambient air quality standards, permitting requirements for minor sources of air pollution, enforcement authorities, procedures for administrative appeals and judicial review in Tribal court, requirements for area sources of fugitive dust and fugitive particulate matter, general prohibitory rules, and source category-specific emission limitations. The purpose of the proposed TIP is to implement, maintain, and enforce the National Ambient Air Quality Standards (NAAQS) in the GRIC reservation. The intended effect of today's proposed action is to make the GRIC TIP federally enforceable.

The Environmental Protection Agency (EPA) Region 6 is publishing a direct final notice of deletion of the Rogers Road Municipal Landfill Superfund Site (Site), located near Jacksonville, Pulaski County, Arkansas from the National Priorities List (NPL). The NPL, promulgated pursuant to Section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). This direct final deletion is being published by EPA with the concurrence of the State of Arkansas, through the Arkansas Department of Environmental Quality (ADEQ), because EPA has determined that all appropriate response actions under CERCLA, other than operation, maintenance, and five-year reviews, have been completed. However, this deletion does not preclude future actions under Superfund.

EPA is approving Minnesota's request to amend its State Implementation Plan (SIP) for sulfur dioxide (SO2). The Minnesota Pollution Control Agency (MPCA) submitted the SIP revision request to EPA on November 23, 2009, and supplemented it on March 3, 2010. EPA's approval revises SIP requirements applicable to Saint Mary's Hospital, located in Rochester, Minnesota, by adding a 2500 kilowatt (KW) reciprocating internal combustion engine (RICE) electric generator and reducing the allowable diesel fuel sulfur content for two existing RICE electric generators. The revision also includes administrative changes in the identification of emissions units. These revisions are included in a joint Title I/Title V document for Saint Mary's Hospital, which replaces the document currently approved into the SIP for the facility. These revisions will result in reducing the SO2 impact in the Rochester area, and strengthen the existing SO2 SIP.

The EPA is taking direct final action to approve revisions to the New Mexico State Implementation Plan (SIP). These revisions concern two separate actions. First, we are approving revisions to regulations on Emission Inventories (EIs) submitted by stationary sources of air pollutants. EIs are critical for the efforts of state, local, and federal agencies to attain and maintain the National Ambient Air Quality Standards (NAAQS) that EPA has established for criteria pollutants such as ozone, particulate matter, and carbon monoxide. The revisions add new definitions; modify existing definitions; and require stationary sources of air pollutants located in New Mexico outside of Bernalillo County to report emissions location information, PM2.5 emissions, and ammonia emissions to New Mexico Environment Department (NMED). The revisions also allow NMED to require speciation of hazardous air pollutants for emissions reporting. Second, we are approving revisions to the New Mexico Administrative Code (NMAC), 20.2.1 NMACGeneral Provisions. We are adding a new definition for Significant Figures into the New Mexico SIP. The EPA is approving these two actions pursuant to section 110 of the Federal Clean Air Act (CAA, Act).

In compliance with the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), this document announces that an Information Collection Request (ICR) has been forwarded to the Office of Management and Budget (OMB) for review and approval. This is a request to renew an existing approved collection. The ICR which is abstracted below describes the nature of the collection and the estimated burden and cost.
