A meeting was held between Countywide and OEPA, wherein a proposal was made for the standard to be achieved prior to performing a baseline gas flow. Countywide will formalize this proposal and submit it soon. Note: This table presents one-time field activities and does not address recurring activities such as liquid level measurements, downhole temperature profiles, liquid sampling, etc.
