II. Judicial Review

Section 307(b)(1) of the Clean Air Act (CAA) indicates which Federal Courts of Appeals have venue for petitions for review of final EPA actions. This section provides, in part, that the petitions for review must be filed in the Court of Appeals for the District of Columbia Circuit if: (i) The agency action consists of “nationally applicable regulations promulgated, or final action taken, by the Administrator,” or (ii) such actions are locally or regionally applicable, if “such action is based on a determination of nationwide scope or effect and if in taking such action the Administrator finds and publishes that such action is based on such a determination.”

The EPA has determined that its denial of the petition for reconsideration is nationally applicable for purposes of CAA section 307(b)(1) because the actions directly affect the OSWRO NESHAP, which is a nationally applicable regulation. Thus, any petitions for review of the EPA's decision denying the petitioners' request for reconsideration must be filed in the United States Court of Appeals for the District of Columbia Circuit by July 15, 2016.

III. Description of Action

On March 18, 2015, the EPA promulgated a final rule amending the OSWRO NESHAP based on the RTR conducted for the OSWRO source category. 80 FR 14248, March 18, 2015. The EPA amended the OSWRO NESHAP to revise provisions related to emissions during periods of startup, shutdown, and malfunction; to add requirements for electronic reporting of performance testing; to add monitoring requirements for pressure relief devices (PRDs); to revise routine maintenance provisions; to clarify provisions for open-ended valves and lines and for some performance test methods and procedures; and to make several minor clarifications and corrections. Subsequent to publishing the final rule, the EPA received a petition for reconsideration submitted jointly by Eastman Chemical Company and the American Chemical Council (dated May 18, 2015). This petition sought reconsideration of two of the amended provisions of the OSWRO NESHAP: (1) The equipment leak provisions for connectors, and (2) the requirement to monitor PRDs on portable containers. The EPA considered the petition and supporting information along with information contained in the OSWRO NESHAP amendment rulemaking docket (Docket ID No. EPA-HQ-OAR-2012-0360) in reaching a decision on the petition. The Agency granted reconsideration of the PRD monitoring requirement in a letter to the petitioners dated February 8, 2016. In separate letters to the petitioners dated May 5, 2016, the Administrator denied reconsideration of the equipment leak provisions for connectors and explained the reasons for the denial in these letters. These letters are available in the OSWRO NESHAP amendment rulemaking docket.
