The Wyoming Oil and Gas Conservation Commission is once again considering a proposal to dispose of oil and gas wastewater in the Madison aquifer in Fremont County.

The proposal would allow waste from the Moneta Divide project to be injected into a 15,000 foot aquifer. Encana originally petitioned for the aquifer exemption back in 2013. Aethon Energy has since purchased the field.

The water in the aquifer is considered to be good quality, but the company has argued that because it is so deep, it won’t ever be used as a drinking water source.

Encana broke ground today on a treatment facility for produced water -- the contaminated water that's pulled up along with oil in the drilling process. The Neptune Water Treatment Facility will sit outside of Casper and serve the Moneta Divide field, which currently has about 300 wells but could eventually have more than 4-thousand. The facility will treat some of the produced water from current wells. A controversial plan to inject wastewater into the Madison Aquifer is another water disposal method Encana plans to use in the field.

Encana’s Moneta Divide Natural Gas and Oil Development Project outside of Casper is still waiting for an Environmental Impact Statement, but it is slated to receive a record of decision in 2016. The proposed four thousand well development has brought up questions surrounding water management and air quality. But at the legislature’s Joint Mineral, Business, and Economic Development Interim Committee meeting yesterday, Natrona County Commissioner Rob Hendry said he wants the project to go ahead.
