§ 63.9913What test methods and other procedures must I use to demonstrate initial compliance with the emission limits for particulate matter and PM10?
(a) You must conduct each performance test that applies to your affected source according to the requirements in § 63.7(e)(1).
(b) To determine compliance with the applicable emission limits for particulate matter in Table 1 to this subpart, you must follow the test methods and procedures in paragraphs (b)(1) and (2) of this section.
(1) Determine the concentration of particulate matter according to the following test methods in appendix A to 40 CFR part 60:
(i) Method 1 to select sampling port locations and the number of traverse points. Sampling ports must be located at the outlet of the control device and prior to any releases to the atmosphere.
(ii) Method 2, 2F, or 2G to determine the volumetric flow rate of the stack gas.
(iii) Method 3, 3A, or 3B to determine the dry molecular weight of the stack gas.
(iv) Method 4 to determine the moisture content of the stack gas.
(v) Method 5 or 5D, as applicable, to determine the concentration of particulate matter.
(vi) Method 201 or 201A, as applicable, to determine the concentration of PM10.
(2) Collect a minimum sample volume of 60 dry standard cubic feet (dscf) during each particulate matter or PM10 test run. Three valid test runs are needed to comprise a performance test.
(c) Compute the mass emissions rate in pounds per hour (lbs/hr) for each test run using Equation 1 of this section:
Elbs/hr = Mass emissions rate of particulate matter or PM10 (lbs/hr);
Cs = Concentration of particulate matter or PM10 in the gas stream, grains per dry standard cubic feet (gr/dscf);
Qstd = Volumetric flow rate of stack gas, dry standard cubic feet per minute (dscfm);
60 = Conversion factor, minutes per hour (min/hr); and
7,000 = Conversion factor, grains per pound (gr/lb).
