  • (1) Sample(s) collected during release event used to calculate emissions
    (2) No sample collected during release event. Used another sample from the same day
    (3) No sample collected during release event. Used mass spec composition data.
    (4) No sample collected during release event. Used another representative sample based on engineering judgment.
    (5) No sample collected during release event. Used 12-month rolling emission factor based on the flaring events > 1 MMSCFD
    (6) No sample collected during release event. Used 12-month rolling emission factor
    (7) Negative meter noise overwritten as zero.
    (8) Positive meter noise <0.5 ft/sec="" overwritten="" as="">
    (9) Removed raw readings > 0.5 ft/sec that did NOT represent real flow to flare. Monitoring indicates vent gas pressure was not sufficient to break water seal.
    (10) Vent gas volume based on engineering judgment during periods of monitor inoperation
