Current through December 26, 2024

Section 250-RICR-120-05-27.10 - Recordkeeping and Reporting Requirements

A. A record of all measurements, performance evaluations, calibration checks, and maintenance or adjustments for each continuous emission monitor shall be maintained.

B. A written report of excess emissions, as measured by a continuous emission monitor shall be submitted to the Office of Air Resources for every calendar quarter. All quarterly reports shall be received no later than thirty (30) days following the end of each calendar quarter and shall include the following information:

1. Date and time of commencement and completion of each period of excess emissions and the magnitude of the excess emissions.

2. Identification of the suspected reason for the excess emissions and any corrective action taken.

3. The date and time period any continuous emission monitor was inoperative, except for zero and span checks and the nature of system repairs or adjustments.

4. The date and time periods of any missing data or periods where compliance could not be determined and the steps taken to cure the cause of the missing data.

5. In the event none of the above items have occurred such information shall be stated in the report.

C. The fuel used in each combustion unit subject to RACT must be measured and recorded monthly.

1. As an alternative to measuring and recording fuel used in each combustion unit, a stationary source may petition the Director to use one of the following methods to demonstrate compliance with RACT:

a. The fuel used in multiple combustion units which have equivalent NOx emission rates may be measured and recorded monthly using a single metering device. If more than one type of fuel is used in the multiple combustion units, the amount of each type fuel must be measured and recorded monthly;

b. The fuel used in multiple combustion units which have different NOx emission rates may be measured and recorded monthly using a single metering device. If more than one type of fuel is used in the multiple combustion units, the amount of each type fuel must be measured and recorded monthly. The total NOx emissions for these units will be determined using the emission rate of the highest NOx emitting combustion unit.

D. Stationary sources subject to §27.8.2(A)(2) of this Part shall obtain a certification from the fuel supplier for each shipment of distillate oil that includes the following information:

1. The name of the oil supplier, and;

2. That the oil complies with the specification for fuel oil numbers 1 or 2, as defined by the American Society for Testing and Materials in ASTM D 396-18 "Standard Specification for Fuel Oils."

E. All stationary sources combusting residual fuel oil shall obtain a certification from the fuel supplier for each shipment of residual oil that includes the following information:

1. The name of the oil supplier;

2. The nitrogen content of the oil from which the shipment came or of the shipment itself;

3. The method used to determine the nitrogen content of the oil. ASTM test methods D 3228-08, D 4629-17, incorporated above in § 27.4(B) of this Part, or any other method approved by the Director and the EPA may be used; and,

4. The location of the oil when the sample was drawn for analysis to determine the nitrogen content of the oil, specifically including whether the oil was sampled as delivered to the stationary source or whether the sample was drawn from oil in storage at the oil supplier's or oil refiner's facility or another location.

F. As an alternative to the fuel supplier certification required in § 27.10(E) of this Part, a stationary source may elect to sample the fuel oil prior to combustion. Sampling and analysis shall be conducted after each new shipment of residual oil is received. Samples shall be collected from the fuel tank immediately after the fuel tank is filled and before any oil is combusted. The residual oil must be sampled and analyzed according to ASTM methods which have the prior approval of or are required by the Director.

G. Copies of all fuel supplier certifications or fuel oil analyses shall be maintained at the facility and be made accessible for review by the Director or the designated personnel of the Director and EPA. These records shall include a certified statement, signed by the owner or operator of the stationary source, that the records represent all of the fuel combusted during the quarter.

H. All stationary sources subject to §27.8.2(C) of this Part shall maintain records verifying that a tune-up has been performed in accordance with the procedure described in § 27.11 of this Part that includes the following information:

1. The date the tune-up was performed;

2. The name of the person who performed the tune-up; and,

3. The final excess oxygen setting.

4. The O₂/CO curve or O₂/smoke curve that has been developed as part of this procedure.

I. Stationary sources subject to an emissions cap pursuant to the provisions of § 27.6(B) of this Part shall:

1. Measure and record monthly the fuel used in each combustion unit with a heat input capacity greater than or equal to one million Btu per hour;

2. On a monthly basis, no later than fifteen (15) days after the first of each month, determine the fuel usage and quantity of NOx emitted for the previous twelve-month period for each combustion unit or for the stationary source;

3. Notify the Office of Air Resources, in writing within thirty (30) days of the end of the month, whenever NOx emissions exceed the emissions cap; or,

4. As an alternative to measuring and recording fuel used in each combustion unit as required in § 27.10(I)(1) of this Part, a stationary source may petition the Director to use one of the following methods to demonstrate compliance with an emissions cap:

J. All stationary sources with emergency standby internal combustion engines satisfying the provisions of § 27.6(C) of this Part shall:

1. Install and maintain a non-resettable elapsed time meter to indicate, in cumulative hours, the elapsed engine operating time;

2. On a monthly basis, no later than fifteen (15) days after the first of each month, determine and record the hours of operation for each engine for the previous twelve-month period; and

3. Notify the Office of Air Resources, in writing, whenever the hours of operation in any twelve-month period exceeds five hundred (500) hours.

K. All records required in this Subsection shall be maintained at the stationary source for a minimum of five (5) years and shall be made available to representatives of the Department or EPA upon request.
