N.D. Admin Code 33.1-15-06-03 - Methods of measurement

Testing must be done in accordance with the provisions of chapter 33.1-15-12, as applicable. The reference methods in appendix A to 33.1-15-12, its replacement or applicable alternative methods as approved by the department, shall be used to determine compliance with this chapter as follows:

1. Method 1 for selection of sampling site and sample traverses.

2. Method 2 for stack gas velocity and volumetric flow rate.

3. Method 3 for gas analysis.

4. Method 4 for moisture content.

5. Method 6, 6A, 6C, and 20, as applicable, for concentration of sulfur dioxide. The minimum sampling time shall be at least sixty minutes per run and a test must consist of three runs.

For each run using method 6 for fuel burning equipment the emissions expressed in pounds per million British thermal units [nanogram per joule] shall be determined by the following procedures:

where:

(1) E = pollutant emission, lb/million Btu [ng/j].

(2) C = pollutant concentrations, lb/dscf [ng/dscm].

(3) %O₂ = oxygen content by volume, dry basis.

(4) %CO₂ = carbon dioxide content by volume, dry basis.

The percent oxygen and percent carbon dioxide shall be determined by using the integrated sampling and analysis procedures of method 3.

(5) F_d and F_c = factors listed in method 19 of appendix A of 33.1-15-12.

For facilities firing combinations of fuels the F_d or F_c factors designated in this section shall be prorated in accordance with the applicable formula as follows:

where:

xi = the fraction of total heat input derived from each type of fuel.

(F_d)_ior (F_c)_i = the applicable F_d or F_c factor for each fuel type.

n = the number of fuels being burned in combination.
