Test methods and procedures.

§ 60.474 Test methods and procedures.

(a) For saturators, the owner or operator shall conduct performance tests required in § 60.8 as follows:

(1) If the final product is shingle or mineral-surfaced roll roofing, the tests shall be conducted while 106.6-kg (235-lb) shingle is being produced.

(2) If the final product is saturated felt or smooth-surfaced roll roofing, the tests shall be conducted while 6.8-kg (15-lb) felt is being produced.

(3) If the final product is fiberglass shingle, the test shall be conducted while a nominal 100-kg (220-lb) shingle is being produced.

(b) In conducting the performance tests required in § 60.8, the owner or operator shall use as reference methods and procedures the test methods in appendix A of this part or other methods and procedures as specified in this section, except as provided in § 60.8(b).

(c) The owner or operator shall determine compliance with the particulate matter standards in § 60.472 as follows:

(1) The emission rate (E) of particulate matter shall be computed for each run using the following equation:

E = (cs Qsd)/(PK)

where:

E = emission rate of particulate matter, kg/Mg (lb/ton). cs = concentration of particulate matter, g/dscm (gr/dscf). Qsd = volumetric flow rate of effluent gas, dscm/hr (dscf/hr). P = asphalt roofing production rate or asphalt charging rate, Mg/hr (ton/hr). K = conversion factor, 1000 g/kg [7000 (gr/lb)].
