Code of Federal Regulations Title 40. Protection of Environment § 40.63.9914 What test methods and other procedures must I use to demonstrate initial compliance with chlorine and hydrochloric acid emission limits?

(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 chlorine and hydrochloric acid in Table 1 to this subpart, you must follow the test methods and procedures specified in paragraphs (b)(1) and (2) of this section.

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

Where:

E_lbs/hr = Mass emissions rate of chlorine or hydrochloric acid (lbs/hr);

C_s = Concentration of chlorine or hydrochloric acid in the gas stream, milligrams per dry standard cubic meter (mg/dscm);

Q_std = Volumetric flow rate of stack gas (dscfm);

60 = Conversion factor (min/hr);

35.31 = Conversion factor (dscf/dscm);  and

454,000 = Conversion factor (mg/lb).
