Code of Federal Regulations Title 40. Protection of Environment § 40.63.9913 What test methods and other procedures must I use to demonstrate initial compliance with the emission limits for particulate matter and PM 10 ?

(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.

(c) Compute the mass emissions rate in pounds per hour (lbs/hr) for each test run using Equation 1 of this section:

Where:

E_lbs/hr = Mass emissions rate of particulate matter or PM₁₀ (lbs/hr);

C_s = Concentration of particulate matter or PM₁₀ in the gas stream, grains per dry standard cubic feet (gr/dscf);

Q_std = 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).
