(Adopted 11/22/77, Renumbered 11/21/78, Revised 7/5/83, 3/28/89, 6/4/91)

A. Requirements

  1. The owner or operator of any boiler, steam generator or process heater, with a heat input capacity of between 40 million British Thermal Units (BTU's) per hour and 250 million BTU's per hour, and with a capacity factor of at least 30 percent per year, shall provide, properly install, maintain in good working order, and operate continuous monitoring systems to measure the following pollutants:

  2. a. Oxides of nitrogen

    b. Carbon monoxide

    c. Oxygen

  3. The owner or operator of any boiler, steam generator or process heater, with a heat input capacity of 250 million BTU's or more per hour, shall provide, properly install, maintain in good working order, and operate continuous monitoring systems to measure the following pollutants:

  4. a. Oxides of nitrogen

    b. Carbon dioxide or oxygen

    c. Opacity

  5. The owner or operator of any equipment which emits 2.3 kilograms per hour (5 pounds per hour) or 22.7 kilograms per day (40 pounds per day) or more of any single air contaminant shall, upon written request of the Air Pollution Control Officer, provide, properly install, maintain in good working order, and operate continuous monitoring systems to measure a specified set of air contaminant emissions for a specified reason.

B. Reporting Requirements

  1. The owner or operator of a unit subject to the provisions of Section A of this Rule shall report any violation of any emission standard with which the stationary source is required to comply, as indicated by the records of the monitoring device, in writing to the District within 48 hours after such occurrence. The District shall, in turn, report the violation to the state within five working days after receiving the report of the violation from the owner or operator.

  2. The owner or operator of a unit subject to the provisions of Section A of this Rule shall maintain permanent continuous emission monitoring records, in a form suitable for inspection, for a period of at least four (4) years. Such records shall be made available to the Air Resources Board or the District upon request.

  3. The record shall include:

    a. The date, time and duration of any startup, shutdown or malfunction in the operation of any affected facility.

    b. The results of performance testing, evaluations, calibrations, checks, adjustments, and maintenance of any continuous emission monitors that have been installed pursuant to Section A of this Rule.

    c. Emission Measurements.

    d. Net and Gross megawatt-hours produced, if applicable.

  4. The owner or operator of a unit subject to the provisions of Subsection A.1 or A.2 of this Rule shall submit a written report each calendar quarter to the Air Pollution Control Officer. The report shall be due on the 30th day following the end of the calendar quarter and shall include:

  5. a. The date, time, duration and magnitude of excess emissions, the nature and cause of the excess (if known), the corrective actions taken, and the preventive measures adopted.

    b. The averaging period used for data reporting. For the pollutant/source category in question, this period shall correspond to either the averaging period specified in the applicable rule, or another period, as specified in writing by the Air Pollution Control Officer.

    c. The date, time and duration of each period during which the continuous monitoring system was inoperative, except for zero and span checks, and a description of the system repairs and adjustments undertaken during each period.

    d. A negative declaration when no excess emissions occurred.

  6. The owner or operator of a unit subject to the provisions of Subsection A.3 of this Rule shall, upon written notice from the Air Pollution Control Officer, provide a summary of the data obtained from the continuous monitoring systems. The format of the summary shall be approved in writing by the Air Pollution Control Officer.

  7. Continuous monitoring data shall be reduced according to the procedure established in 40 CFR, Part 51, Appendix P, paragraphs 5.0 through 5.3.3, or by other methods determined to be equivalent by the District, the Air Resources Board and the Environmental Protection Agency.


C. Standards of Performance of Monitoring Systems

  1. The owner or operator of a unit subject to the provisions of Subsection A.1 or A.2 of this Rule shall install, calibrate, operate and maintain continuous monitoring systems in accordance with the specifications in 40 CFR, Part 51, Appendix P, Sections 3.0 through 3.9.5. Section 3.1 of Appendix P shall include 40 CFR, Part 60, Appendix B, Performance Specification 4, for Carbon Monoxide. Equivalent specifications may be established by mutual agreement of the District, the Air Resources Board and the Environmental Protection Agency.

  2. The owner or operator of a unit subject to the provisions of Subsection A.3 of this Rule shall install, calibrate, operate and maintain continuous monitoring systems in accordance with specifications established by the Air Pollution Control Officer.

D. Appeals and Discontinuance of Monitoring

  1. The owner or operator of a unit required to install, maintain and operate continuous monitoring systems pursuant to Subsection A.3 of this Rule may petition the Hearing Board to appeal the Air Pollution Control Officer's decision.

  2. The owner or operator of a unit subject to the provisions of Subsection A.3 of this Rule may be allowed to discontinue use of the continuous monitoring systems if, as determined by the Air Pollution Control Officer, the reason for monitoring no longer exists.

E. Definitions

Definitions appear in 40 CFR, Part 51. Alternative definitions may be established by mutual agreement of the District, the Air Resources Board and the Environmental Protection Agency. Other definitions appear in applicable rules.

  1. "Capacity factor": The ratio of fuel used by an applicable unit compared to the fuel that would have been used by the unit if it had operated at its rated heat input capacity for the entire year. The capacity factor is calculated from a unit's reported fuel consumption.

F. Compliance Schedule

The owner or operator of a unit subject to the provisions of this Rule, but not required to be in compliance with this Rule before March 28, 1989, shall install all necessary equipment and begin monitoring and recording before September 1, 1991.
