<br />DESCRIPTION OF CASTLE SAN[) PIT <br />PERMIT #M-77-213 <br />The permit boundary of this site is identified on the large map by the <br />labels PB 77-213. The description to follow presents a brief history of the <br />permit and then describes the features more or less from a north to south <br />direction. <br />BRIEF HISTORY: This operation began long before there oss a requirement for a <br />permit. Most of the site was fully disturbed by the time a permit was <br />required. Therefore soil resources stripped before permitting were largely <br />lost. The pile labeled "Topsoil Stockpile" is all the soil that was salvaged <br />after permit issuance in 1980. In the 1985 amendment the permit boundary of <br />the original permit was extended southward to include the sand dike that has <br />now been largely removed. This alteration in this permit was done at the <br />suggestion of the Colorado Division of Mined Land Reclamation during an <br />inspection in 1982. <br />PRIMARY USE: The primary function of this site now is as a disposal azea for <br />washings from the Transit Mix operation immediately adjacent to the south. <br />This waste disposal is part of an overall reclamation plan for both operations <br />which will eventually produce a very gently sloping area extending from the <br />back of this operation southward to Bradley Road. This plan was suggested by <br />the MLRD and approved by the MLRB in 1985. <br />SECONDARY USE: Completion of the removal of the sand originally contained in <br />the dike separating this operation from the operation to the south. The two <br />areas yet to be mined are located in the southwest and southeast corners of <br />the permit and aze labeled "UNMINED SAND." <br />NORTH ACCESS ROAD: This is the original access road into this operation and <br />is still used to some extent. Most of the access to this operation though is <br />now from the south through the area where the dike used to be. The north <br />access road would probably need to be ripped prior to reclamation. However, <br />due to continued development in adjacent lands its removal might not actually <br />be necessazy, if adjacent landowners would desire the road to remain for their <br />use. <br />MINOR DISTURBANCE: Two thin strips along the north and south sides of the <br />Fountain Mutual Irrigation Ditch have been final graded and are under <br />revegetation. Actually, much of this is under the control of the ditch <br />company and whatever is done here mist be done with the concurrence of the <br />ditch company. Nevertheless, it is still in the permit area and therefore <br />needs to be included in some way. Slopes in this area are about 2:1 to 2.5:1 <br />and cortgosed mostly of a sandy surface material. <br />SUPPORT BERM/BAC!(FILL: Located about halfway up the north slope of the pit is <br />a fill area that is approximately at the final elevation of the depth of fill <br />to be placed in the pit at the end of reclamation. At present this fill <br />serves the purpose of providing additional support for the concrete lined <br />irrigation ditch. If reclaimed at this time the south slope of this fill <br />would need to be reduced in steepness so that a 3:1 slope to the bottom of the <br />pit is produced. No material is available in the pit to accomplish this as <br />the plan calls for a final slope constructed out of sediment basin disposal, <br />as suggested by MLRD in 1982 and approved by MLRB in 1985. <br />Page 2 Bonding Information M-73-007/M-77-213 January 7, 1992 <br />
