§ 98.353 Calculating GHG emissions.
(a) For each anaerobic reactor and anaerobic lagoon, estimate the annual mass of CH4 generated according to the applicable requirements in paragraphs (a)(1) through (a)(2) of this section.
(1) If you measure the concentration of organic material entering the anaerobic reactors or anaerobic lagoon using methods for the determination of chemical oxygen demand (COD), then estimate annual mass of CH4 generated using Equation II–1 of this section.
Where:
(2) If you measure the concentration of organic material entering an anaerobic reactor or anaerobic lagoon using methods for the determination of 5-day biochemical oxygen demand (BOD5), then estimate annual mass of CH4 generated using Equation II–2 of this section.
Where:
