SAN DIEGO COUNTY AIR POLLUTION CONTROL DISTRICT

RULE 260.444 - PERFORMANCE TEST PROCEDURES

(a) The performance test for affected facilities complying with Rule 260.442 without the use of add-on controls shall be identical to the procedures specified in Rule 260.443(a).

(b) The performance test for affected facilities controlled by a solvent recovery device shall be conducted as follows:
 

1.  The performance test shall be a one calendar month test and not the average of three runs as specified in Rule 260.8(f).
2. The weighted average mass of VOC per mass of coating solids applied for a one calendar month period shall be determined as specified in Rules 260.443(a)(1) and 260.443 (a)(2).
3. Calculate the required percent overall VOC emission reduction as specified in Rule 260.443(b).
4. Inventory VOC usage and VOC recovery for a one calendar month period.
5. Determine the percent overall VOC emission reduction as specified in Rule 260.443(c).

(c) The performance test for affected facilities controlled by a solvent destruction device shall be conducted as follows:
 

1. The performance of the solvent destruction device shall be determined by averaging the results of three test runs as specified in Rule 260.8(f).
2. Determine for each affected facility prior to each test run the weighted average mass of VOC per mass of coating solids applied being used at the facility. The weighted average shall be determined as specified in Rule 260.443(a). In this application the quantities of W_oi, W_si, and M_i shall be determined for the time period of each test run and not a calendar month as specified in Rule 260.441.
3. Calculate the required percent overall VOC emission reduction as specified in Rule 260.443(b).
4. Determine the percent overall VOC emission reduction of the solvent destruction device by the following equation and procedures:

(i) The owner or operator of the affected facility shall construct the overall VOC emission reduction system so that all volumetric flow rates and total VOC emissions can be accurately determined by the applicable test methods and procedures specified in Rule 260.446(b).

(ii) The owner or operator of an affected facility shall construct a temporary total enclosure around the coating line applicator and flashoff area during the performance test for the purpose of capturing fugitive VOC emissions. If a permanent total enclosure exists in the affected facility prior to the performance test and the Control Officer is satisfied that the enclosure is totally capturing fugitive VOC emissions, then no additional total enclosure will be required for the performance test.

(iii) For each affected facility where the value of R is greater than or equal to the value of R_q calculated in Rule 260.443(b), compliance with Rule 260.442(a)(2) is demonstrated.
