Group A considers all plumes as classied by the aerial team into O&G and non-O&G (waste and agricultural) locations. Qualitative examination of the single non-O&G plume location spatially matched to O&G facilities indicated that the emissions likely did not originate with O&G operations, but with surrounding agricultural operations. O&G accounted for two thirds of emissions estimated from plumes. Group B splits the O&G plumes based upon spatial matching to midstream and production facilities. Approximately two thirds of O&G plumes and estimated emissions were coincident with production facilities.
