Provided in the attached presentation is the requested demonstration. <br /> The literature review, coupled with site specific analyses of biosolids and plant tissues in <br /> land applied areas, show that biosolid copper concentrations are unlikely to present an <br /> obstacle to successful revegetation at the Climax Mine. This literature review should <br /> serve both current information needs to initiate biosolids use at the Climax Mine and <br /> potential future reclamation programs using biosolids within the state. I hope that it may <br /> be of some use to the Division. <br /> Climax and the Summit County Producers are close to the initiation of the program to <br /> deliver, stabilize, and apply the biosolids. I will let you know the formal signing date. <br /> Sincerely, <br /> Bryce R. Romig <br /> Environmental Coordinator <br /> Climax Mine <br />
