Section 250-RICR-120-05-39.11 - Compliance and Performance Testing Requirements

A. Any HMIWI subject to the emissions limitations in §§ 39.9(A) and (B) of this Part, must conduct an initial performance test to demonstrate compliance with those emission limits.

B. A performance test protocol must be submitted for review and approval to the Office of Air Resources at least sixty (60) days prior to conducting the initial or repeat performance test. The use of the bypass stack during a performance test shall invalidate the performance test. The initial performance tests shall be conducted according to the following specifications:

1. All performance tests shall consist of a minimum of three (3) test runs conducted under representative operating conditions;

2. The minimum sampling time shall be one (1) hour per test run unless otherwise required by the Office of Air Resources;

3.40 C.F.R. § 60 Appendix A Method 1, incorporated in § 39.4(A) of this Part, shall be used to select the sampling location and number of traverse points;

4.40 C.F.R. § 60 Appendix A-2 Method 3, 3A or 3B, incorporated in § 39.4(A) of this Part, shall be used for gas composition analysis, including measurement of oxygen concentration. 40 C.F.R. § 60 Appendix A-2 Method 3, 3A or 3B, incorporated in § 39.4(A) of this Part shall be used simultaneously with each reference method.

2. If, in a 3-year period, all three (3) annual performance tests demonstrate compliance with the emission limit for a pollutant (PM, CO, or HCl), the frequency of testing for that pollutant may be reduced to once in three years. If any performance test indicates noncompliance with an applicable emission limit, performance tests for that pollutant shall be conducted annually until all annual performance tests in a 3-year period indicate compliance with the emission limit. In no case shall the period between performance tests for PM, CO, or HCl be longer than three (3) years.

D. For large HMIWI, continuing compliance with the visible emission limits for fugitive emissions from fly ash/bottom ash storage and handling in § 39.9(B)(1) of this Part, must be demonstrated by conducting a performance test using 40 C.F.R. § 60, Appendix A-7 Method 22, incorporated in § 39.4(A) of this Part, no more than twelve (12) months after the initial performance test and annually thereafter.

If inspection of the fabric filter demonstrates that no corrective action is required, no alarm time is counted. If corrective action is required, each alarm is counted as a minimum of one (1) hour. If it takes longer than one (1) hour to initiate corrective action, the alarm time is counted as the actual amount of time taken to initiate corrective action. If the bag leak detection system is used to demonstrate compliance with the opacity limit, this would also constitute a violation of the opacity emissions limit.

M. The owner or operator of an HMIWI equipped with selective noncatalytic reduction technology shall:

1. Establish the maximum charge rate, the minimum secondary chamber temperature, and the minimum reagent flow rate as site specific operating parameters during the initial performance test to determine compliance with the emissions limits;

2. Following the date on which the initial performance test is completed ensure that the affected facility does not operate above the maximum charge rate, or below the minimum secondary chamber temperature or the minimum reagent flow rate measured as 3-hour rolling averages (calculated each hour as the average of the previous three (3) operating hours) at all times. Operating parameter limits do not apply during performance tests.
