SAN DIEGO COUNTY AIR POLLUTION CONTROL DISTRICT

RULE 260.49a - REPORTING REQUIREMENTS

(a) For sulfur dioxide, nitrogen oxides, and particulate matter emissions, the performance test data from the initial performance test and from the performance evaluation of the continuous monitors (including the transmissometer) are submitted to the Control Officer.

(b) For sulfur dioxide and nitrogen oxides the following information is reported to the Control Officer for each 24-hour period.

  1. Calendar date.
  2. The average sulfur dioxide and nitrogen oxide emission rates (ng/J or lb/million Btu) for each 30 successive boiler operating days, ending with the last 30-day period in the quarter; reasons for non-compliance with the emission standards; and, description of corrective actions taken.
  3. Percent reduction of the potential combustion concentration of sulfur dioxide for each 30 successive boiler operating days, ending with the last 30-day period in the quarter; reasons for non-compliance with the standard; and, description of corrective actions taken.
  4. Identification of the boiler operating days for which pollutant or dilutent data have not been obtained by an approved method for at least 18 hours of operation of the facility; justification for not obtaining sufficient data; and description of corrective actions taken.
  5. Identification of the times when emissions data have been excluded from the calculation of average emission rates because of startup, shutdown, malfunction (NOx only), emergency conditions (SO2 only), or other reasons, and justification for excluding data for reasons other than startup, shutdown, malfunction, or emergency conditions.
  6. Identification of "F" factor used for calculations, method of determination, and type of fuel combusted.
  7. Identification of times when hourly averages have been obtained based on manual sampling methods.
  8. Identification of the times when the pollutant concentration exceeded full span of the continuous monitoring system.
  9. Description of any modifications to the continuous monitoring system which could affect the ability of the continuous monitoring system to comply with Performance Specifications 2 or 3.

(c) If the minimum quantity of emission data as required by Rule 260.47a is not obtained for any 30 successive boiler operating days, the following information obtained under the requirements of Rule 260.46a(h) is reported to the Control Officer for that 30-day period;

  1. The number of hourly averages available for outlet emissions rates (no) and inlet emission rates (ni) as applicable.
  2. The standard deviation of hourly averages for outlet emission rates (so) and inlet emission rates (si) as applicable.
  3. The lower confidence limit for the mean outlet emission rate (Eo*) and the upper confidence limit for the mean inlet emission rate (Ei*) as applicable.
  4. The applicable potential combustion concentration.
  5. The ratio of the upper confidence limit for the mean outlet emission rate (Eo*) and the allowable emission rate (Estd) as applicable.

(d) If any standards under Rule 260.43a are exceeded during emergency conditions because of control system malfunction, the owner or operator of the affected facility shall submit a signed statement:

  1. Indicating if emergency conditions existed and requirements under Rule 260.46a(d) were met during each period, and
  2. Listing the following information:

    (i) Time periods the emergency condition existed;

    (ii) Electrical output and demand on the owner or operator's electric utility system and the affected facility;

    (iii) Amount of power purchased from interconnected neighboring utility companies during the emergency period;

    (iv) Percent reduction in emissions achieved;

    (v) Atmospheric emission rate (ng/J) of the pollutant discharged; and

    (vi) Actions taken to correct control system malfunction.

(e) If fuel pretreatment credit toward the sulfur dioxide emission standard under Rule 260.43a is claimed, the owner or operator of the affected facility shall submit a signed statement:

  1. Indicating what percentage cleaning credit was taken for the calendar quarter, and whether the credit was determined in accordance with the provision of Section 60.48a and Method 19 of Appendix A of Part 60, Chapter I, Title 40, Code of Federal Regulations.
  2. Listing the quantity, heat content, and date each pretreated fuel shipment was received during the previous quarter; the name and location of the fuel pretreatment facility; and the total quantity and total heat content of all fuels received at the affected facility during the previous quarter.

(f) For any periods for which opacity, sulfur dioxide or nitrogen oxides emissions data are not available, the owner or operator of the affected facility shall submit a signed statement indicating if any changes were made in operation of the emission control system during the period of data unavailability. Operations of the control system and affected facility during periods of data unavailability are to be compared with operation of the control system and affected facility before and following the period of data unavailability.

(g) The owner or operator of the affected facility shall submit a signed statement indicating whether:

  1. The required continuous monitoring system calibration, span, and drift checks or other periodic audits have or have not been performed as specified.
  2. The data used to show compliance was or was not obtained in accordance with approved methods and procedures of this regulation and is representative of plant performance.
  3. The minimum data requirements have or have not been met; or, the minimum data requirements have not been met for errors that were unavoidable.
  4. Compliance with the standards has or has not been achieved during the reporting period.

(h) For the purposes of the reports required under Rule 260.7, periods of excess emissions are defined as all 6-minute periods during which the average opacity exceeds the applicable opacity standards under Rule 260.42a(b). Opacity levels in excess of the applicable opacity standard and the date of such excesses are to be submitted to the Control Officer each calendar quarter.

(i) The owner or operator of an affected facility, shall submit the written reports required under this rule and Subpart A to the Control Officer for every calendar quarter. All quarterly reports shall be postmarked by the 30th day following the end of each calendar quarter.
