Approval and Promulgation of Air Quality Implementation Plans; State of Nevada; Regional Haze State and Federal Implementation Plans; BART Determination for Reid Gardner Generating Station
Apr 12, 2012 (Environmental Protection Agency Documents and Publications/ContentWorks via COMTEX) --
SUMMARY: EPA is proposing to partially approve and partially disapprove the remaining portion of a revision to the Nevada State Implementation Plan (SIP) to implement the regional haze program for the first planning period through July 31, 2018. This Notice proposes to approve the chapter of Nevada's Regional Haze SIP that requires Best Available Retrofit Technology (BART) for emissions limits of oxides of nitrogen (NOX) from Units 1 and 2 at the Reid Gardner Generating Station (RGGS). We are proposing to disapprove the NOX emissions limit for Unit 3. We are also proposing to disapprove the provision of the RGGS BART determination that sets a 12-month rolling average for Units 1 through 3. This Notice proposes to promulgate a Federal Implementation Plan (FIP) that establishes certain requirements for which the State, in a letter dated March 22, 2012, has agreed to submit a SIP revision. The FIP sets an emissions limit of 0.20 lbs/MMBtu (pounds per million British thermal units) for Unit 3 as BART and requires the determination of emissions from Units 1 through 3 based on a 30-day rolling average (averaged across all three units). In a prior action, EPA approved Nevada's Regional Haze SIP except for its BART determination for NOX for RGGS Units 1 through 3.

Instructions: Direct your comments to Docket ID No. EPA-R09-OAR-2011-0130. Our policy is that EPA will include all comments received in the public docket without change. EPA may make comments available online at http://www.regulations.gov, including any personal information provided, unless the comment includes information claimed to be Confidential Business Information (CBI) or other information whose disclosure is restricted by statute. Do not submit information that you consider to be CBI or otherwise protected through http://www.regulations.gov or email. The http://www.regulations.gov web site is an "anonymous access" system, which means EPA will not know your identity or contact information unless you provide it in the body of your comment. If you send an email comment directly to EPA, without going through http://www.regulations.gov, EPA will include your email address as part of the comment that is placed in the public docket and made available on the Internet. If you submit an electronic comment, EPA recommends that you include your name and other contact information in the body of your comment and with any disk or CD-ROM you submit. If EPA cannot read your comment due to technical difficulties and cannot contact you for clarification, EPA may not be able to consider your comment. Electronic files should avoid the use of special characters, any form of encryption, and be free of any defects or viruses. For additional information about EPA's public docket visit the EPA Docket Center homepage at http://www.epa.gov/epahome/dockets.htm.
Docket: All documents in the docket are listed in the http://www.regulations.gov index. Although it is listed in the index, some information is not publicly available (e.g., CBI or other information whose disclosure is restricted by statute). Certain other material, such as copyrighted material, voluminous records or large maps, will be publicly available only in hard copy form. Publicly available docket materials are available either electronically at http://www.regulations.gov or in hard copy at the Planning Office of the Air Division, Air-2, EPA Region 9, 75 Hawthorne Street, San Francisco, CA 94105. EPA requests you contact the individual listed in the FOR FURTHER INFORMATION CONTACT section to view the hard copy material of the docket. You may view the hard copy material of the docket Monday through Friday, 9-5:30 PST, excluding federal holidays.
FOR FURTHER INFORMATION CONTACT: Thomas Webb, U.S. EPA, Region 9, Planning Office, Air Division, Air-2, 75 Hawthorne Street, San Francisco, CA 94105. Thomas Webb can be reached at telephone number (415) 947-4139 and via electronic mail at firstname.lastname@example.org.

VIII. Statutory and Executive Order Reviews
The CAA requires each state to develop plans, referred to as SIPs, to meet various air quality requirements. A state must submit its SIPs and SIP revisions to us for approval. Once approved, a SIP is enforceable by EPA and citizens under the CAA, and is, therefore, federally enforceable. If a state fails to make a required SIP submittal or if we find that a state's required submittal is incomplete or unapprovable, then we must promulgate a FIP to fill this regulatory gap. CAA section 110(c)(1). 40 U.S.C. 7410(c).
This proposed action is intended to fulfill the requirement that states adopt and EPA approve SIPs that address regional haze. In 1990, Congress added section 169B to the CAA to address regional haze issues, and we promulgated regulations addressing regional haze in 1999. 64 FR 35714 (July 1, 1999), codified at 40 CFR part 51, subpart P. For a more detailed discussion please see our prior proposed action at 76 FR 36450 (June 22, 2011).
