Navajo Generating Station and Air Visibility Regulations: Alternatives and Impacts (Revised)


Book Description

Pursuant to the Clean Air Act, the U.S. Environmental Protection Agency (EPA) announced in 2009 its intent to issue rules for controlling emissions from Navajo Generating Station that could affect visibility at the Grand Canyon and at several other national parks and wilderness areas. The final rule will conform to what EPA determines is the best available retrofit technology (BART) for thecontrol of haze-causing air pollutants, especially nitrogen oxides. While EPA is ultimately responsible for setting Navajo Generating Station?s BART standards in its final rule, it will be the U.S. Department of the Interior?s responsibility to manage compliance and the related impacts. This study aims to assist both Interior and EPA by providing an objective assessment of issues relating to thepower sector.

Book Description

Air Quality State Implementation Plans - Approvals and Promulgations - Navajo Nation - Regional Haze Requirements for Navajo Generating Station (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Air Quality State Implementation Plans - Approvals and Promulgations - Navajo Nation - Regional Haze Requirements for Navajo Generating Station (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 The Environmental Protection Agency (EPA) is promulgating a source-specific Federal Implementation Plan (FIP) requiring the Navajo Generating Station (NGS), a coal-fired power plant located on the Navajo Nation near Page, Arizona, to achieve reductions in oxides of nitrogen (NO X) required under the Best Available Retrofit Technology (BART) provisions of the Clean Air Act (CAA) and the Regional Haze Rule (RHR). On February 5, 2013, EPA issued a proposed BART determination for NGS and an alternative to BART. In a supplemental proposal on October 22, 2013, EPA proposed to approve a new alternative plan, based on an agreement developed by a group of stakeholders known as the Technical Work Group (TWG). EPA is finalizing the alternative to BART described in our supplemental proposal. This rule is consistent with the TWG Agreement, including a lifetime cap in total emissions of NO X from NGS over 2009-2044 (2009-2044 NO X Cap). Our final action will achieve greater emissions reductions than BART and is expected to significantly reduce the impact of NGS on visibility at 11 mandatory Class I Federal areas. The operator of NGS must implement one of several alternative operating scenarios to achieve the necessary emission reductions to comply with the 2009-2044 NO X Cap.

Air Pollution


Book Description

This report is concerned with the benefits and costs of installing sulfur dioxide controls at the Navajo Generating Station, which was thought to produce sulfur dioxide emissions that contributed to impaired visibility at the Grand Canyon. The report: determines the effect on emissions reductions and the assoc. costs that resulted from the negotiated agree. used by EPA in making its decision compared to its initial proposal; identifies the visibility improve. EPA estimated would result from the emissions controls and the means by which these improvements were determined; and determines how contingent valuation was used to estimate the monetary value of visibility improve.

Source-Specific Federal Implementation Plan - Navajo Generating Station - Navajo Nation (Us Environmental Protection Agency Regulation) (Epa) (2018 Edition)


Book Description

Source-Specific Federal Implementation Plan - Navajo Generating Station - Navajo Nation (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Source-Specific Federal Implementation Plan - Navajo Generating Station - Navajo Nation (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 The Environmental Protection Agency (EPA) is promulgating a source-specific Federal Implementation Plan (FIP) to regulate emissions from the Navajo Generating Station (NGS), a coal-fired power plant located on the Navajo Indian Reservation near Page, Arizona. EPA proposed the NGS FIP on September 12, 2006, to establish federally enforceable limitations for TSP, SO 2, and opacity, and control measures for dust. The limits had previously been established in the Arizona SIP. EPA promulgated the Tribal Authority Rule in 1998, clarifying that state air quality regulations generally did not apply to facilities on Indian reservations and that EPA should fill the regulatory gap as necessary or appropriate. This action fills the regulatory gap for the NGS facility.
