Northern Cheyenne Objectives
Determine the best coalbed methane development scenarios and water handling
Environmental Benefit - Water Issues, Northern Cheyenne
Water is of sufficient quality for domestic and livestock uses
The Coalbed water is unusable for irrigation for most of the soils in the area
Northern Cheyenne Project Results
Geology complete
Methane reserves calculated
Produced water to be reinjected in sandstone formations and stored for later use
Gas Environmental Program
Technology and policy solutions for the environmental barriers that limit domestic production
Federal Lands Access Reduce Permitting Times Science-based Stipulations
Coal Bed Natural Gas - Water Issues Treatment Technologies Educational Materials
1995 2000 2005 2010 2015
2006 Provide data on the term effects of coalbed methane production on coal seam aquifers.
2009 Provide impact analyses of coalbed methane production on wildlife species of concern (such as threatened and endangered species) and , where necessary, develop mitigation strategies that allow development to proceed while protecting the environment.
2005 Resolve questions surrounding the environmental effects of hydraulic fracturing.
Goal: By 2010 provide the solutions to current environmental issues and questions that will allow a 25% increase in natural gas produced from coal seams.
Coalbed Methane (CBM)
Issues/Barriers: CBM development, especially in the West, is a fairly recent phenomenon and new issues may arise
Water issues surrounding CBM development, especially in the West, have become an emotionally charged and all barriers cannot be resolved through science or technology.
Hydraulic fracturing continues to be an issue despite strong evidence, endorsed by the EPA, that hydraulic fracturing does not cause contamination of underground sources of drinking water.
The NEPA process in Montana is moving slowly and once it is completed, litigation may cause further delays in CBM development.
2007 Develop best management practices for treating and/or discharging coalbed methane water to the surface.
2006 Provide fate and transport data to determine the environmental impacts of infiltration ponds in the Powder and Tongue River basins.

Mission and GoalsMission: Encourage Maximum Recovery and Use of Domestic
Oil and Gas Resources by Improving Environmental Protection
Provide improved and advanced technologies that enable industry to reduce
compliance costs and improve environmental protectionDevelop sound scientific data to support cost
effective, risk-based regulatory decisions by State and Federal agenciesImprove communication and technology transfer among industry, government, and the publicStreamline regulatory processes to maximize
use of oil and gas
