Engineer to present workshop on impact of uranium mining

Val Green, a mining and waste water engineer with decades of experience in the study and regulation of mines, will give a workshop titled, “Local and Site-Specific Factors:  Uranium Mining and Milling at Coles Hill” on Sept. 13, from 7 to 9 p.m. at the Olde Dominion Agricultural Foundation in Chatham.  Admission is free.  

The workshop is sponsored by Blue Ridge Environmental Defense League ( through a grant from the Western Mining Action Network.

Site-specific factors that Green will consider include:

Predictors of acid rock drainage — does Coles Hill bear the earmarks?

• Nature of the material that may seep from Coles Hill mill tailings containment, and what will need to be done to keep it out of the groundwater

• Nature of how the Pittsylvania County wind patterns may affect distribution of radioactive dust during the active mining phase

• Whether Coles Hill soil and rock structures will affect the risk of releases from mill tailings containment at Coles Hill

• Whether the need to divert surface water from the mining area may result in the massive reconstruction of a FEMA Class A Flood Zone

• Plus an extensive question and answer period.

Green has served as expert witness for over 10 groups seeking to stop mines.  He taught mining engineering at New Mexico Institute of Mining and Technology in Socorro, N.M. from 1989 to 1994.  He has performed evaluation and review of environmental assessments, environmental impact statements and permit applications for mining operations.  

He has extensive experience working in compliance and enforcement of National Environmental Policy Act, Clean Air Act, and Clean Water Act.  He served on the New Mexico Mining Commission from 1993 to 1995, where he provided technical assistance in the formulation and writing of the New Mexico mining regulations.  

Green is a graduate of Clemson University with a BS in civil engineering, and holds an MS in environmental engineering from University of Texas.  He is a member of the American Society of Civil Engineers and the Society for Mining, Metallurgy and Exploration.
