40 CFR 98.445 – Procedures for estimating missing data
A complete record of all measured parameters used in the GHG quantities calculations is required. Whenever the monitoring procedures cannot be followed, you must use the following missing data procedures:
(a) A quarterly flow rate of CO
(1) Another calculation methodology listed in § 98.444(a)(1) must be used if possible.
(2) If another method listed in § 98.444(a)(1) cannot be used, a quarterly flow rate value that is missing must be estimated using a representative flow rate value from the nearest previous time period.
(b) A quarterly mass or volume of contents in containers received that is missing must be estimated as follows:
(1) Another calculation methodology listed in § 98.444(a)(2) must be used if possible.
(2) If another method listed in § 98.444(a)(2) cannot be used, a quarterly mass or volume value that is missing must be estimated using a representative mass or volume value from the nearest previous time period.
(c) A quarterly CO
(1) Another calculation methodology listed in § 98.444(a)(3) must be used if possible.
(2) If another method listed in § 98.444(a)(3) cannot be used, a quarterly concentration value that is missing must be estimated using a representative concentration value from the nearest previous time period.
(d) A quarterly quantity of CO
(e) For any values associated with CO
(f) The quarterly quantity of CO
(g) You must estimate the mass of CO
(h) You must estimate other missing data as required by your approved MRV plan.
