Memorandum 1 III IIIIII IIIIIII III IN REPLY RLPLR TO United States Dep~lrtment of the Interior 3600 BUREAU OF LAND MANAGEMENT Resource Area Headquarters ederal Building Camino del Rio ,~~ , Durango; Colorado 81301 RECEIVES July 11,~ 1981 JUL 2 7 ~ggl To: Area Manager-, SJRA From: Geologist, SJRA MINED LAND RECLAMATION Cob. Dept. of Natural Resources Subject: Examination of C&J Gravel Products, Inc. Operation (T.34N., R.9W., Section lO, NE ;NW a) On July 16, 1981, Mike Long, Colorado Division of Mined Land Reclamation, Scott Hogrefe and I conducted an examination of the subject gravel operation on private land. My observation from the pit area is that the highwall on the west does not present as great a problem as it originally appeared. Recontouring could probably be accomplished and not impact the public land to the west. The north highwall is the most critical in that it is near vertical, approximately 75-100 feet in height, and is within approximately 30 feet of tfie line between private and public land. It appeared that some material had come down from above as a result of recent heavy rainfall. During the time we were near the highwall, material (small amounts) was falling from the face. I took photos from various angles of the west and north sides of the excavation area. (Will be attached later). As we were about to leave, Mr. Carl Strohecker arrived and we spent some time discussing what was intended for reclamation. Mr. Strohecker 'said they - plan to take overburden material from the west side and place it on and at the base of the highwall on the north. Mr. Jack Gilleland arrived and said the same concerning the reclamation. Mike Long and I have the same question and the same opinion as to the feasibility of the reclamation plan. We question whether there is enough mates°i al available to stabilize the north highwall and whether they can obtain the slope indicated in their Colorado State permit (3:l). Mike and I agree that all that can be done at this time is make periodic checks and just observe the situation and what reclamation efforts take place.
