Approvals and Promulgations of Implementation Plans - Montana - State Implementation Plan and Regional Haze Federal Implementation Plan (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Approvals and Promulgations of Implementation Plans - Montana - State Implementation Plan and Regional Haze Federal Implementation Plan (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 The Environmental Protection Agency (EPA) is promulgating a Federal Implementation Plan (FIP) to address regional haze in the State of Montana. EPA developed this FIP in response to the State's decision in 2006 to not submit a regional haze State Implementation Plan (SIP) revision. The FIP satisfies requirements of the Clean Air Act (CAA or "the Act") that require states, or EPA in promulgating a FIP, to assure reasonable progress towards the national goal of preventing any future and remedying any existing man-made impairment of visibility in mandatory Class I areas. In addition, EPA is approving one of the revisions to the Montana SIP submitted by the State of Montana through the Montana Department of Environmental Quality on February 17, 2012, specifically, the revision to the Montana Visibility Plan that includes amendments to the "Smoke Management" section, which adds a reference to Best Available Control Technology (BACT) as the visibility control measure for open burning as currently administered through the State's air quality permit program. This change was made to meet the requirements of the Regional Haze Rule. EPA will act on the remaining February 17, 2012 revisions in the State's submittal in a future action.

Air Quality State Implementation Plans - Approvals and Promulgations - Montana - Regional Haze Federal Implementation Plan (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 - Montana - Regional Haze Federal Implementation Plan (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 The Environmental Protection Agency (EPA) is finalizing revisions pursuant to section 110 of the Clean Air Act (CAA) to the Federal Implementation Plan (FIP) addressing regional haze in the State of Montana. The EPA promulgated a FIP on September 18, 2012, in response to the State's decision in 2006 to not submit a regional haze State Implementation Plan (SIP). We proposed revisions to that FIP on April 14, 2017, and are now finalizing those revisions. Specifically, the EPA is finalizing revisions to the FIP's requirement for best available retrofit technology (BART) for the Trident cement kiln owned and operated by Oldcastle Materials Cement Holdings, Inc. (Oldcastle), located in Three Forks, Montana. In response to a request from Oldcastle, and in light of new information that was not available at the time we originally promulgated the FIP, we are revising the nitrogen oxides (NO X) emission limit for the Trident cement kiln. We are also correcting errors we made in our FIP regarding the reasonable progress determination for the Blaine County #1 Compressor Station and the instructions for compliance determinations for particulate matter (PM) BART emission limits at electrical generating units (EGUs) and cement kilns. This action does not address the U.S. Court of Appeals for the Ninth Circuit's June 9, 2015 vacatur and remand of portions of the FIP regarding the Colstrip and Corette power plants; we plan to address the court's remand in a separate action.

Approvals and Promulgations of Implementation Plans - North Dakota - Regional Haze State Implementation Plan, etc. (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Approvals and Promulgations of Implementation Plans - North Dakota - Regional Haze State Implementation Plan, etc. (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA is partially approving and partially disapproving a revision to the North Dakota State Implementation Plan (SIP) addressing regional haze submitted by the Governor of North Dakota on March 3, 2010, along with SIP Supplement No. 1 submitted on July 27, 2010, and part of SIP Amendment No. 1 submitted on July 28, 2011. These SIP revisions were 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"). EPA is promulgating a Federal Implementation Plan (FIP) to address the gaps in the plan resulting from our partial disapproval of North Dakota's Regional Haze (RH) SIP.

NM031.030 Approvals and Promulgations of State Implementation Plans - New Mexico - Regional Haze Rule Requirements for Mandatory Class I Areas (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the NM031.030 Approvals and Promulgations of State Implementation Plans - New Mexico - Regional Haze Rule Requirements for Mandatory Class I Areas (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA is approving New Mexico State Implementation Plan (SIP) revisions submitted on July 5, 2011, and December 1, 2003, by the Governor of New Mexico addressing the regional haze requirements for the 16 Class I areas covered by the Grand Canyon Visibility Transport Commission Report and a separate submittal for other Federal mandatory Class I areas. We are taking final approval action on all components of the State's submittals except for the submitted nitrogen oxides (NO X) Best Available Retrofit Technology (BART) determination for the San Juan Generating Station (SJGS). We are also approving several SIP submissions offered as companion rules to the regional haze plan, including submitted regulations for the Western Backstop Sulfur Dioxide Trading Program, for the inventorying of emissions, for smoke management, and open burning. These SIP revisions were submitted to address the requirements of the Clean Air Act (CAA or Act) which 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 taking this action pursuant to section 110 of the CAA.

NM041.8000 Approvals and Promulgations of Implementation Plans - New Mexico - Federal Implementation Plan for Interstate Transport of Pollution Affect (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the NM041.8000 Approvals and Promulgations of Implementation Plans - New Mexico - Federal Implementation Plan for Interstate Transport of Pollution Affect (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA is disapproving a portion of the State Implementation Plan (SIP) revision received from the State of New Mexico on September 17, 2007, for the purpose of addressing the "good neighbor" requirements of section 110(a)(2)(D)(i) of the Clean Air Act (CAA or Act) for the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS or standards) and the 1997 fine particulate matter (PM 2.5) NAAQS. In this action, EPA is disapproving the New Mexico Interstate Transport SIP provisions that address the requirement of section 110(a)(2)(D)(i)(II) that emissions from New Mexico sources do not interfere with measures required in the SIP of any other state under part C of the CAA to protect visibility. We have found that New Mexico sources, except the San Juan Generating Station, are sufficiently controlled to eliminate interference with the visibility programs of other states. EPA is promulgating a Federal Implementation Plan (FIP) to address this deficiency by implementing nitrogen oxides (NO X) and sulfur dioxide (SO 2) emission limits necessary at the San Juan Generating Station (SJGS), to prevent such interference. EPA found in January 2009 that New Mexico had failed to submit a SIP addressing certain regional haze (RH) requirements, including the requirement for best available retrofit technology (BART). The Clean Air Act required EPA to promulgate a FIP to address RH requirements by January 2011. This FIP addresses the RH BART requirement for NO X for SJGS. In addition, EPA is implementing sulfuric acid (H 2 SO 4) hourly emission limits at the SJGS, to minimize the contribution of this compound to visibility impairment. This action is being taken under section 110 and part C of the CAA.

NM029.35 Approvals and Promulgations of State Implementation Plans - Albuquerque-Bernalillo County, NM - Interstate Transport Affecting Visibility (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the NM029.35 Approvals and Promulgations of State Implementation Plans - Albuquerque-Bernalillo County, NM - Interstate Transport Affecting Visibility (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA is approving the City of Albuquerque-Bernalillo County, New Mexico State Implementation Plan (SIP) revisions submitted by the Governor of New Mexico on July 28, 2011 addressing the regional haze requirements for the mandatory Class I areas under 40 CFR 51.309. The EPA finds that these revisions to the State Implementation Plan (SIP) and associated rules meet the requirements of the Clean Air Act (CAA) and comply with the provisions of 40 CFR 51.309, thereby meeting requirements for reasonable progress for the 16 Class I areas covered by the Grand Canyon Visibility Transport Commission Report for approval of the plan through 2018. We are also approving SIP submissions offered as companion rules to the Section 309 regional haze plan, specifically, rules for the Sulfur Dioxide Emissions Inventory Requirements and the Western Backstop Trading Program, submitted on December 26, 2003, September 10, 2008, and May 24, 2011, and rules for Open Burning, submitted on December 26, 2003 and July 28, 2011. These SIP revisions were submitted to address the requirements of the 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.

Approvals and Promulgations of Implementation Plans - Revisions to Nevada State Implementation Plan - Stationary Source Permits (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Approvals and Promulgations of Implementation Plans - Revisions to Nevada State Implementation Plan - Stationary Source Permits (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA is finalizing a limited approval and limited disapproval of revisions to the applicable state implementation plan for the State of Nevada. The revisions include new or amended State rules governing applications for, and issuance of, permits for stationary sources, but not including review and permitting of major sources and major modifications under parts C and D of title I of the Clean Air Act. EPA is taking this action under the Clean Air Act obligation to take action on State submittals of revisions to state implementation plans. The intended effect of the limited approval and limited disapproval action is to update the applicable state implementation plan with current State rules with respect to permitting, and to set the stage for remedying deficiencies in the permitting rules with respect to certain new or revised national ambient air quality standards. This limited disapproval action would not trigger sanctions under section 179 of the Clean Air Act but does trigger an obligation on EPA to promulgate a Federal Implementation Plan unless the State of Nevada corrects the deficiencies, and EPA approves the related plan revisions, within two years of the final action.
