§ 98.424 Monitoring and QA/QC requirements.
(a) Determination of quantity. (1) Reporters following the procedures in § 98.423(a) shall determine quantity using a flow meter or meters located in accordance with this paragraph.
(i) If the CO2 stream is segregated such that only a portion is captured for commercial application or for injection, you must locate the flow meter according to the following:
(A) For reporters following the procedures in § 98.423(a)(3)(i), you must locate the flow meter(s) after the point of segregation.
(B) For reporters following the procedures in paragraph (a)(3)(ii) of § 98.423, you must locate the main flow meter(s) on the captured CO2 stream(s) prior to the point of segregation and the subsequent flow meter(s) on the CO2 stream(s) for on-site use after the point of segregation. You may only follow the procedures in paragraph (a)(3)(ii) of § 98.423 if the CO2 stream(s) for on-site use is/are the only diversion(s) from the main, captured CO2 stream(s) after the main flow meter location(s).
(ii) Reporters that have a mass flow meter or volumetric flow meter installed to measure the flow of a CO2 stream that meets the requirements of paragraph (a)(1)(i) of this section shall base calculations in § 98.423 of this subpart on the installed mass flow or volumetric flow meters.
(iii) Reporters that do not have a mass flow meter or volumetric flow meter installed to measure the flow of the CO2 stream that meets the requirements of paragraph (a)(1)(i) of this section shall base calculations in § 98.423 of this subpart on the flow of gas transferred off site using a mass flow meter or a volumetric flow meter located at the point of off-site transfer.
