Air Quality State Implementation Plans - Approvals and Promulgations - Response to Petition for Rulemaking - Restatement and Update of EPA's SSM Policy (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 - Response to Petition for Rulemaking - Restatement and Update of EPA's SSM Policy (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 The Environmental Protection Agency (EPA) is taking final action on a petition for rulemaking filed by the Sierra Club (Petitioner) that concerns how provisions in EPA-approved state implementation plans (SIPs) treat excess emissions during periods of startup, shutdown or malfunction (SSM). Further, the EPA is clarifying, restating and revising its guidance concerning its interpretation of the Clean Air Act (CAA or Act) requirements with respect to treatment in SIPs of excess emissions that occur during periods of SSM. The EPA evaluated existing SIP provisions in a number of states for consistency with the EPA's interpretation of the CAA and in light of recent court decisions addressing this issue. The EPA is issuing a finding that certain SIP provisions in 36 states (applicable in 45 statewide and local jurisdictions) are substantially inadequate to meet CAA requirements and thus is issuing a "SIP call" for each of those 36 states. Further, the EPA is establishing a due date for states subject to this SIP call action to submit corrective SIP revisions. Finally, this final action embodies the EPA's updated SSM Policy as it applies to SIP provisions. The SSM Policy provides guidance to states for compliance with CAA requirements for SIP provisions applicable to excess emissions during SSM events.

Air Quality State Implementation Plans - Approvals and Promulgations - 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 - 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 revising portions of the Arizona Regional Haze Federal Implementation Plan (FIP) applicable to the Coronado Generating Station (Coronado) and the Cholla Power Plant (Cholla). In response to a petition for reconsideration from the Salt River Project Agricultural Improvement and Power District (SRP), the owner and operator of Coronado, we are replacing a plant-wide compliance method with a unit-specific compliance method for determining compliance with the best available retrofit technology (BART) emission limits for nitrogen oxides (NO X) from Units 1 and 2 at Coronado. While the plant-wide limit for NO X emissions from Units 1 and 2 was established as 0.065 lb/MMBtu, we are now setting a unit-specific limit of 0.065 lb/MMBtu for Unit 1 and 0.080 lb/MMBtu for Unit 2. In addition, we are revising the work practice standard in the FIP for Coronado. Finally, we are removing the affirmative defense for malfunctions, which applied to both Coronado and Cholla.

Approval and Promulgation of State Implementation Plan Revisions - Air Pollution Control Rules (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Approval and Promulgation of State Implementation Plan Revisions - Air Pollution Control Rules (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 The Environmental Protection Agency is approving State Implementation Plan (SIP) revisions submitted by the State of North Dakota on April 6, 2009. Specifically, EPA is approving revisions to the North Dakota air pollution control rules regarding prevention of significant deterioration of air quality, and partially approving the SIP revision "Interstate Transport of Air Pollution" addressing the requirements of Clean Air Act section 110(a)(2)(D)(i) for the 1997 PM 2.5 and 8-hour ozone National Ambient Air Quality Standards (NAAQS). These revisions, referred to as the Interstate Transport of Air Pollution SIP, address the requirements of Clean Air Act section 110(a)(2)(D)(i) for the 1997 8-hour ozone and 1997 PM 2.5 National Ambient Air Quality Standards (NAAQS). In this action, EPA is approving the North Dakota Interstate Transport SIP provisions that address the requirement of section 110(a)(2)(D)(i)(I) that emissions from the state's sources do not "contribute significantly" to nonattainment of the 1997 8-hour ozone NAAQS and the 1997 PM 2.5 NAAQS in any other state. In addition, EPA is approving the provisions of this SIP that address the requirement of section 110(a)(2)(D)(i)(II) that emissions from the state's sources do not interfere with measures required in the SIP of any other state under part C of the Clean Air Act (CAA) to prevent "significant deterioration of air quality." EPA will act at a later date on the North Dakota Interstate Transport SIP provisions that address the remaining two requirements of section 110(a)(2)(D)(i), that emissions from the state's sources do not "interfere with maintenance" of the 1997 8-hour ozone and 1997 PM 2.5 NAAQS in any other state, and do not interfere with measures required in the SIP of any other state to "protect visibility." This action is being taken under section 110 of the Clean Air Act.
