.AMCASTLE ROCK CONSULTING ENHANCING TRADITIONAL SownoNs wITII/NNovATIoN Request for Technical Revision File No. M-1977-559 Attachment No. 1 Description of Proposed Technical Revision EXISTING PERMIT REQUIREMENTS FOR RECLAMATION The proposed future land use of East Pit listed in the 1977 mining permit application as commercial use as a marine equipment sales location. The alternate land use listed was"a private recreation area and a habitat that will favor wildlife." The attached Area Map and Detailed Reclamation Area Map for the East Pit shows grass seeding and tree planting on the reclaimed batch plant site, with dirt access roads encircling the batch plant area and extending along the southern boundary. The existing shop building, concrete aggregate bins and concrete fueling bays(all still existing)were to be removed. Topsoil was to be spread to a depth of six inches, before the approved seed mix was planted, mulched and fertilized. Total tree planting was to include 212 Russian olives. The West Pit final land use was originally "open range and pond", which was changed to "wildlife habitat" in a Technical Revision in 1992. The reclamation required grading to 3:1 slopes, before seeding and re-vegetating. STATUS OF EXISTING RECLAMATION The East Pit slopes are sloped and well vegetated along the western, eastern and southern sides of the East Pit, as well as the northern slope around the plant area. Some of the slopes east of the plant site are backfilled with concrete and still require some sloping, earthwork, top-soiling and seeding. Structures would require removal, per the original Reclamation Plan, prior to grading, topsoil spreading and reseeding with mulch and fertilizer. The lower areas in the southeast portion of the plant site are nicely revegetated, with new cottonwood trees growing. The West Pit slopes have been graded and revegetated, requiring routine mowing for weed control, and are presumably ready for release. The access road along the east side of the West Pit has not been seeded. REQUESTED CHANGES TO RECLAMATION PLAN • No change to the proposed future use of the affected land is requested. • The existing shop building and concrete aggregate storage bunkers to the south will remain, to the extent allowed by Fremont County zoning regulations. The shop building will be cleaned and used for various storage purposes. The future Land Owner will obtain county building permits to construct a roof over the aggregate bunkers, and convert them into useful covered storage for equipment and materials, not visible from Mackenzie Avenue. • The concrete structures previously used for fuel and oil storage will be demolished into rubble, and used on-site for slope stability and fish habitat, as described below. 536EAST 2 DAVEVUE CAS77.EROCI, CO 801018 (303)660-86013 (303)663-511 FAX STAAPE7FR9PE0A0L.00M
