The issuance of this plan approval does not prevent the future adoption by the Department of any rules, regulations or standards, or the issuance of orders necessary to comply with the requirements of the Federal Clean Air Act or the Pennsylvania Air Pollution Control Act, or to achieve or maintain ambient air quality standards. The issuance of this plan approval shall not be construed to limit the Department's enforcement authority. This plan approval authorizes temporary operation of the source(s) covered by this plan approval provided the following conditions are met. (a) When construction, installation, modification, or reactivation is being conducted, the permittee shall provide written notice to the Department of the completion of the activity approved by this plan approval and the permittee's intent to commence operation at least five (5) working days prior to the completion of said activity. The notice shall state when the activity will be completed and when the permittee expects to commence operation. When the activity involves multiple sources on different time schedules, notice is required for the commencement of operation of each source. (b) Pursuant to 25 Pa. Code § 127.12b (d), temporary operation of the source(s) is authorized to facilitate the shakedown of sources and air cleaning devices, to permit operations pending the issuance of a permit under 25 Pa. Code Chapter 127, Subchapter F (relating to operating permits) or Subchapter G (relating to Title V operating permits) or to permit the evaluation of the air contaminant aspects of the source. (c) This plan approval authorizes a temporary operation period not to exceed 180 days from the date of commencement of operation, provided the Department receives notice from the permittee pursuant to paragraph (a), above. (d) The permittee may request an extension of the 180-day shakedown period if further evaluation of the air contamination aspects of the source(s) is necessary. The request for an extension shall be submitted, in writing, to the Department at least 15 days prior to the end of the initial 180-day shakedown period and shall provide a description of the compliance status of the source, a detailed schedule for establishing compliance, and the reasons compliance has not been established.

What are my general requirements for complying with this subpart? Plan approval terms and conditions. Associate Director Office of Enforcement and Compliance Assistance (3AP20) U.S. EPA, Region III 1650 Arch Street Philadelphia, PA 19103-2029 and The Pennsylvania Department of Environmental Protection Air Quality Program Manager 208 W. Third Street, Suite 101 Williamsport, PA 17701-6448 Pursuant to the best available technology requirements of 25 Pa. Code Section 127.1 and 127.12, high efficiency inlet air filters shall be used in the air inlet section of Source ID P183. (a) You must operate and maintain your stationary combustion turbine, air pollution control equipment, and monitoring equipment in a manner consistent with good air pollution control practices for minimizing emissions at all times including during startup, shutdown, and malfunction. (b) When an affected unit with heat recovery utilizes a common steam header with one or more combustion turbines, the owner or operator shall either: (1) Determine compliance with the applicable NOX emissions limits by measuring the emissions combined with the emissions from the other unit(s) utilizing the common heat recovery unit; or (2) Develop, demonstrate, and provide information satisfactory to the Administrator on methods for apportioning the combined gross energy output from the heat recovery unit for each of the affected combustion turbines. The Administrator may approve such demonstrated substitute methods for apportioning the combined gross energy output measured at the steam turbine whenever the demonstration ensures accurate estimation of emissions related under this part. The permittee shall comply with the work practicce standards of 40 CFR Part 60 Section 60.4333 for Source ID P183. Pursuant to the best available technology requirements of 25 Pa. Code Sections 127.1 and 127.12, Source ID P183 shall be a one of the following:a Siemens model 5000F4 DLN natural-gas-fired combustion turbines (CT) and steam turbines (ST) equipped with naturalgas-fired duct burners (DB) and heat recovery steam generators (HRSG). The maximum heat input rating of each CT is 2259 MMBtu/hr (high heating value, HHV) and 2037 MMBtu/hr (lower heating value, LHV). Each DB will have a maximum heat input rating of 282.9 MMBtu/hr (HHV) OR VI.
