DEPARTMENT OF NATURAL RESOURCES <br />Davitl H. Getches, Executive Director <br />MINED LAND RECLAMATION DIVISION <br />DAVID C. SHELTON, Director <br />Richartl D. Lamm <br />Governor <br />February 14,1984 <br />Memo <br />To: Ed Bischoff/Dorchester No.l File <br />From: Bob Liddle <br />The following is a summary of the outstanding Issues with regard to the <br />pending Dorchester No. 1 decision. <br />1. We still need Dorchester to solicit comments from J. Thompson, surface <br />owner, concerning the post-mining land use. <br />2. The contents of annual hydrologic reports will need to be discussed. <br />Dorchester is not committing to reevaluating the PHC yearly, instead they want <br />to summarize data. <br />3.Dorchester needs to supply water quantity data for Oak Creek for the <br />Division to complete the PHC prior to permit issuance. We discussed this in <br />past meetings but they never responded with data. <br />4. We need to discuss the issue of the Thompson well with Dorchester. We need <br />information from Dorchester on the aquifer location, characteristics, and <br />probable impacts from dewatering and subsidence. We will probably need a more <br />detailed water replacement plan. <br />5. Dorchester still has not supplied a complete hydrology map. We need to <br />discuss the specifics of map requirements with them. <br />6. Jim Pendleton needs to review the portal sealing, road stability, angle of <br />draw, and subsidence report format responses from Dorchester. I did not revise <br />these topics in the findings document pending his review. <br />7. The issue of undermining Thompson ranch and mining adjacent to the park <br />will need to be discussed with Dorchester. <br />8. I am proposing a bond amount which is appr. E80,000 more than Dorchester <br />proposed. We will probably need to discuss this with them. <br />At this point the document 1s ready to turn back to Dorchester. However, we <br />could also wait until Jim reviews his sections and I could quickly revise the <br />document with his and your comments when I return Friday, Feb. 7,1984. If it <br />is to gD out the secretary needs to reformat the document to fit the new <br />printer. <br />The document and this memo is on my disk to my "1n" basket. <br />Doc. 9377E <br />423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203 Tel.
