The demand for domestic energy coupled with new technologies that allow developers to tap shale gas deposits has led to the rapid expansion of gas exploration and development in the state. Balancing those economic benefits while maintaining stewardship of the land, water and air, the West Virginia Department of Environmental Protection is taking a proactive approach as it works to oversee a complex industry.
