(a <br /> Golder Associates <br /> CONSULTING GEOTECHNICAL AND MINING ENGINEERS <br /> August 29, 1984 Our Ref: 843-2054 <br /> Mid-Continent Resources , Inc. <br /> Post Office Box 158 <br /> Carbondale , Colorado 81623 <br /> Attention: Mr. Douglas W. Bowman <br /> Environmental Coordinator <br /> Dear Doug: <br /> Attached please find a copy of our letter of May 18, 1984, describing <br /> proposed reclamation test sections. This includes a description of <br /> each test section , the reclamation concept, and method of reclamation. <br /> Also included are cross sections showing existing and reclaimed config- <br /> urations for each test section. The proposed test locations are indi- <br /> cated on both the test section descriptions and cross sections ; it will <br /> be necessary for you to review them and decide on the final test loca- <br /> tions. <br /> We hope this information is sufficient for you to initiate construction <br /> of the test sections. In addition to the details contained in this let- <br /> ter, the following points should be considered. <br /> o Surface water should be diverted around test fills such that construc- <br /> tion does not impede existing drainages and surface water flows do not <br /> cause erosion of the fills. <br /> o All test fills should be compacted in lifts not exceeding 12 inches in <br /> loose thickness by routing the construction equipment uniformly over <br /> the surface of the fill . Final in-situ fill density should be at least <br /> 90 percent of AASHTO T-99 (Standard Proctor). <br /> o Excavation and fill construction should be approximately between the <br /> stations and at the slopes indicated on the sections. We have made <br /> no estimate of the excavation and fill volumes. <br /> o A site visit by a Golder engineer is scheduled following construction <br /> of the test sections. Following this visit, a report to MLRD will be <br /> prepared. The report is due on November 30, 1984. The report will <br /> present as-built drawings and recommendations on further monitoring. <br /> GOLDER ASSOCIATES INC • 17301 W COLFAX AVENUE.SUITE 275.GOLDEN(DENVER) COLCRADO 80401 U S A •TELEPHONE 1303,278 8662 <br />
