Red text identifies options. Select the option that applies to the source and change the text to black. Delete red text that does not apply and renumber conditions if necessary.

Blue text is guidance or notes on the use of the template. DELETE ALL BLUE TEXT PRIOR TO ISSUING THE FINAL PERMIT OR SUBMITTING IT WITH A PERMIT APPLICATION.

THIS TEMPLATE IS ONLY FOR STATIONARY COMBUSTION TURBINE(S) EQUIPPED WITH OXIDATION CATALYST. If the stationary combustion turbine is not equipped with an oxidation catalyst, you must petition the USEPA for operating limitations.

If this template is being used for an ROP Reopening or Renewal, AND the MACT conditions were established in a PTI, the appropriate footnotes which reference enforceability must be added to each applicable condition in the template.

This template is for any new or reconstructed stationary combustion turbine located at a major source of HAP emissions.

EXISTING STATIONARY COMBUSTION TURBINE. A stationary combustion turbine is existing if commenced construction or reconstruction of the stationary combustion turbine on or before January 14, 2003. A change in ownership of an existing stationary combustion turbine does not make that stationary combustion turbine a new or reconstructed stationary combustion turbine.

NEW STATIONARY COMBUSTION TURBINE. A stationary combustion turbine is new if commenced construction of the stationary combustion turbine after January 14, 2003.

RECONSTRUCTED STATIONARY COMBUSTION TURBINE. A stationary combustion turbine is reconstructed if you meet the definition of reconstruction in 40 CFR 63.2 and reconstruction is commenced after January 14, 2003.

Per 40 CFR 63.6090(b)(4), EXISTING STATIONARY COMBUSTION TURBINES in all subcategories do not have to meet the requirements of 40 CFR Part 63, Subpart YYYY. No initial notification is necessary for any existing stationary combustion turbine, even if a new or reconstructed turbine in the same category would require an initial notification. DUCT BURNERS AND WASTE HEAT RECOVERY UNITS are considered steam generating units and are not covered under 40 CFR Part 63, Subpart YYYY per 63.6092.

DESCRIPTION

40 CFR Part 63, Subpart YYYY requirements for each new / reconstructed (choose one) stationary combustion turbine which is a lean premix gas-fired stationary combustion turbine, a lean premix oil-fired stationary combustion turbine, a diffusion flame gas-fired stationary combustion turbine, or a diffusion flame oil-fired stationary combustion turbine (choose at least one) with a rated peak power output of equal to or greater than 1.0 megawatt (MW) and equipped with an oxidation catalyst located at a major source of HAP emissions. Stationary combustion turbine means all equipment, including but not limited to the turbine, the fuel, air, lubrication and exhaust gas systems, control systems (except emissions control equipment), and any ancillary components and sub-components comprising any simple cycle stationary combustion turbine, any regenerative/recuperative cycle stationary combustion turbine, the combustion turbine portion of any stationary cogeneration cycle combustion system, or the combustion turbine portion of any stationary combined cycle steam/electric generating system. {May add specifics for the Emission Unit(s) in this flexible group.}

III. PROCESS/OPERATIONAL RESTRICTION(S)

The permittee must operate and maintain each stationary combustion turbine, including associated air pollution control equipment and monitoring equipment, in a manner consistent with safety and good air pollution control practices for minimizing emissions. The general duty to minimize emissions does not require the permittee to make any further efforts to reduce emissions if levels required by the applicable standard have been achieved. Determination of whether a source is operating in compliance with operation and maintenance requirements will be based on information available to the AQD which may include, but is not limited to, monitoring results, review of operation and maintenance procedures, review of operation and maintenance records, and inspection of the source. (40 CFR 63.6105(c))

Use if a continuous monitoring system (CMS) is required.

The permittee must develop and implement a continuous monitoring system (CMS) quality control program according to 40 CFR 63.8(d)(1) through (2). Each quality control program shall include, at a minimum, a written protocol that describes procedures for each of the following operations:

Initial and any subsequent calibration of the CMS; (40 CFR 63.8(d)(2)(i))

Determination and adjustment of the calibration drift of the CMS; (40 CFR 63.8(d)(2)(ii))

Preventive maintenance of the CMS, including spare parts inventory; (40 CFR 63.8(d)(2)(iii))

The permittee must keep these written procedures on record for the life of the affected source or until the affected source is no longer subject to the provisions of this part, to be made available for inspection, upon request, by the AQD. If the performance evaluation plan is revised, the permittee shall keep previous (i.e., superseded) versions of the performance evaluation plan on record to be made available for inspection, upon request, by the AQD. (40 CFR 63.6125(e))

IV. DESIGN/EQUIPMENT PARAMETER(S)

The permittee using an oxidation catalyst must continuously monitor and maintain the 4-hour rolling average of the catalyst inlet temperature within the range suggested by the catalyst manufacturer. The permittee is not required to use the catalyst inlet temperature data that is recorded during engine startup in the calculations of the 4-hour rolling average catalyst inlet temperature. (40 CFR 63.6100, 40 CFR 63.6125(a), 40 CFR 63.6140, 40 CFR Part 63, Subpart YYYY, Tables 2.1 and 5.1)

Except for monitor malfunctions, associated repairs, and required quality assurance or quality control activities (including, as applicable, calibration checks and required zero and span adjustments of the monitoring system), the permittee must conduct all parametric monitoring at all times the stationary combustion turbine is operating. Do not use data recorded during monitor malfunctions, associated repairs, and required quality assurance or quality control activities for meeting the requirements of 40 CFR Part 63, Subpart YYYY, including data averages and calculations. The permittee must use all the data collected during all other periods in assessing the performance of the control device or in assessing emissions from each stationary combustion turbine. (40 CFR 63.6135(a) and (b))
