The equation for calculating the hourly nitrogen oxides emissions for each kiln located at an account in pounds per hour

Where:

EH             =          total hourly NOX emissions from each kiln located at the account, in pounds per hour;

C                =          the block hour average NOX concentration, determined in accordance with subsection (a)(1) of this section, in parts per million by volume (ppmv), dry basis;

F                =          the block average exhaust flow rate, determined in accordance with subsection (a)(2) of this section, in dry standard cubic feet per minute; and

K               =          conversion factor, 1.194 x 10-7 pounds per standard cubic foot per ppmv (40 CFR Part 60, Appendix A, Method 19, Table 19-1).
