We meant to mention: The West Virginia Department of Environmental Protection released on January 8, 2010, an industry guidance document for oil and gas producers looking at possible Marcellus Shale production. Its purpose:
[T]o assist well operators in planning for the drilling and operation of these wells and the associated need to either dispose of or reuse large water volume fracture treatment wastes. It is intended to facilitate compliance with applicable statutory and regulatory requirements and to generally minimize negative environmental impacts associated with these activities, by promoting the use of necessary best management practices.
