40 CFR 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 CO
(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 CO
(ii) Reporters that have a mass flow meter or volumetric flow meter installed to measure the flow of a CO
(iii) Reporters that do not have a mass flow meter or volumetric flow meter installed to measure the flow of the CO
(2) Reporters following the procedures in paragraph (b) of § 98.423 shall determine quantity in accordance with this paragraph.
(i) Reporters that supply CO
(ii) Reporters that supply CO
(3) Importers or exporters that import or export CO
(4) All flow meters, scales, and load cells used to measure quantities that are reported in § 98.423 of this subpart shall be operated and calibrated according to the following procedure:
(i) You shall use an appropriate standard method published by a consensus-based standards organization if such a method exists. Consensus-based standards organizations include, but are not limited to, the following: ASTM International, the American National Standards Institute (ANSI), the American Gas Association (AGA), the American Society of Mechanical Engineers (ASME), the American Petroleum Institute (API), and the North American Energy Standards Board (NAESB).
(ii) Where no appropriate standard method developed by a consensus-based standards organization exists, you shall follow industry standard practices.
(iii) You must ensure that any flow meter calibrations performed are NIST traceable.
(5) Reporters using Equation PP-2 of this subpart and measuring CO
(i) You may use a method published by a consensus-based standards organization. Consensus-based standards organizations include, but are not limited to, the following: ASTM International (100 Barr Harbor Drive, P.O.

The method(s) used shall be documented in the Monitoring Plan required under § 98.3(g)(5).
(ii) You may follow an industry standard method.
(b) Determination of concentration. (1) Reporters using Equation PP-1 or PP-2 of this subpart shall sample the CO
(2) Methods to measure the composition of the CO
(c) You shall convert the density of the CO
