Current through Register Vol. 50, No. 9, September 20, 2024

A. Applicability

1. This regulatory permit authorizes the installation and use of stationary internal combustion engines, including, but not limited to, electrical power generators, firewater pumps, and air compressors, subject to the requirements established herein, upon notification by the administrative authority that the application (i.e., notification form) submitted in accordance with Subsection L of this Section has been determined to be complete. This regulatory permit also authorizes the associated fuel storage tank provided the capacity of the tank is less than 10,000 gallons.

2. This regulatory permit may be used to authorize the use of both permanent and temporary engines.

3. This regulatory permit does not apply to:
a. emergency electrical power generators deemed insignificant in accordance with item B.45 in the insignificant activities list in LAC 33:III.501.B.5; and

b. nonroad engines, as defined in LAC 33:III.502.A.

4. This regulatory permit shall not be used to authorize use of an engine that combusts noncommercial fuels, including used crankcase oil or any other used oil, facility byproducts, or any other type of waste material.

5. This regulatory permit shall not be used to authorize use of an engine that, when considering potential emissions from the engine and potential emissions from the remainder of the stationary source, would result in the creation of a major source of criteria pollutants, hazardous air pollutants, or toxic air pollutants.

B. Definitions

Emergency Engine- any stationary internal combustion engine (ICE) whose operation is limited to emergency situations (e.g., involuntary power curtailment, power unavailability, maintenance activity that requires the main source of power to be shut down) and required readiness testing and maintenance checks.

C. Opacity

1. Limitations
a. Smoke. The emission of smoke shall be controlled so that the shade or appearance of the emission is not darker than 20 percent average opacity, except that the emissions may have an average opacity in excess of 20 percent for not more than one 6-minute period in any 60 consecutive minutes.

b. Particulate Matter. The emission of particulate matter shall be controlled so that the shade or appearance of the emission is not denser than 20 percent average opacity, except that the emissions may have an average opacity in excess of 20 percent for not more than one 6-minute period in any 60 consecutive minutes.

c. When the presence of uncombined water is the only reason for failure of an emission to meet the requirements of this Subsection, this Subsection will not apply.

2. Monitoring and Recordkeeping for Emergency Engines
a. The permittee shall inspect each emergency engine's stack for visible emissions once each month or at each readiness testing event if the engine is tested at a frequency less than monthly.

b. If visible emissions are detected for more than one 6-minute period over a 60 consecutive minute test period using Method 22 of 40 CFR 60, Appendix A, the permittee shall conduct a 6-minute opacity reading in accordance with Method 9 of 40 CFR 60, Appendix A, during the next required visible emissions check.

c. If the shade or appearance of the emission is darker than 20 percent average opacity (per Method 9), the permittee shall take corrective action to return the engine to its proper operating condition, and the 6-minute opacity reading in accordance with Method 9 shall be repeated. The permittee shall notify the Office of Environmental Compliance no later than 30 calendar days after any Method 9 reading in excess of 20 percent average opacity. This notification shall include the date the visual check was performed, results of the Method 9 testing, and a record of the corrective action employed.

d. Records of visible emissions checks shall include the emergency engine's ID number, the engine's serial number, the date the visual check was performed, a record of emissions if visible emissions were detected for a period longer than 6 consecutive minutes, the results of any Method 9 testing conducted, and a record of any corrective action employed. These records shall be kept on-site and available for inspection by the Office of Environmental Compliance.

3. Monitoring and Recordkeeping for Nonemergency Engines
a. The permittee shall inspect each engine's stack for visible emissions no less than once each calendar week. If visible emissions are not detected during the initial six minutes of the inspection, the inspection may be concluded.

b. If visible emissions are detected for more than one six-minute period over a 60 consecutive minute test period using Method 22 of 40 CFR 60, Appendix A, the permittee shall conduct a 6-minute opacity reading in accordance with Method 9 of 40 CFR 60, Appendix A, within three calendar days.

c. If the shade or appearance of the emission is darker than 20 percent average opacity (per Method 9), the permittee shall take corrective action to return the engine to its proper operating condition, and the 6-minute opacity reading shall be repeated in accordance with Method 9. The permittee shall notify the Office of Environmental Compliance no later than 30 calendar days after any Method 9 reading in excess of 20 percent average opacity or, for Part 70 sources, as defined in LAC 33:III.502.A, in accordance with Part 70 General Condition R of LAC 33:III.535.A. This notification shall include the date the visual check was performed, results of the Method 9 testing, and a record of the corrective action employed.

d. Records of visible emissions checks shall be kept on-site and available for inspection by the Office of Environmental Compliance. These records shall include:
i. the engine's ID number;

ii. the engine's serial number;

iii. the date the visual check was performed;

iv. a record of emissions, if visible emissions were detected for more than one six-minute period;

v. the results of any Method 9 testing conducted; and

vi. a record of any corrective action employed.

4. This Subsection shall not apply to engines described in LAC 33:III.1107.B.1 and 2.

D. Fuel Sulfur Content

1. The permittee shall not combust distillate oil that contains greater than 0.5 weight percent sulfur.

2. A statement from the fuel oil supplier that each shipment of distillate oil delivered to the facility complies with the specifications of this Subsection shall be kept on-site and available for inspection by the Office of Environmental Compliance.

E. Operating Time of Emergency Engines

1. Emergency engines may be operated for maintenance checks and readiness testing for a maximum of 100 hours per calendar year, provided that the tests are recommended by the federal, state, or local government; manufacturer; vendor; or insurance company associated with the engine. The owner or operator may petition the department for approval of additional hours to be used for maintenance checks and readiness testing, but a petition is not required if the owner or operator maintains records indicating that federal, state, or local standards require maintenance and testing of emergency engines beyond 100 hours per calendar year.

2. Emergency engines may be operated for up to 50 hours per calendar year in non-emergency situations. The 50 hours of operation in non-emergency situations are counted as part of the 100 hours per calendar year for maintenance and testing.

3. There is no time limit on the use of emergency engines in emergency situations.

4. Operating time of each emergency engine shall be monitored by any technically-sound means, except that a run-time meter shall be required for all permanent units.

5. Operating time of each emergency engine shall be recorded each month, as well as its operating time for the last 12 months. These records shall be kept on-site for five years and available for inspection by the Office of Environmental Compliance.
