C <br />1997. A technical revision to the DMG permit was applied for in June of 1995, which included an <br />expansion of the, disturbed area to allow more stockpiling. Also, expansion was contemplated on the <br />east side of the main channel of the river but [his notion was abandoned and the revision was limited <br />to work within the existing permitted area. It was also during this revision process that Animas <br />Aggregates committed to conduct no mining below the 6645 feet elevation in the River and commit- <br />ted to conduct annual river cross-section studies in order to maintain river stability. In December of <br />1996, the permit was transferred to Mountain Gravel and Constmction Company. Although the DMG <br />permit has been and still is in good standing, mining has not taken place in the River since 1998, until <br />permit issues with the Army Corps of Engineers are resolved. Since mid-1998, Mountain Gravel has <br />been owned by O1dCastle which is now operating as O1dCastle SW Group, Inc dba Four Corners <br />Materials, Inc. <br />Also in 2001, the landowner and Four Corners Materials expressed desire to continue mining and also <br />the possibility of mining an area adjacent to the river within the south portion of the permit area was <br />discussed. This amendment is submitted to allow mining an area of 4.25 acres to a depth of 19.0 feet <br />and will be constructed in an area that currently contains three abandoned sewage treatment ponds. <br />This mining would be done one time only, in the spring of 2002, and would remove approximately <br />122,000 cubic yards of material over an area of 4.7 acres. The small lake produced by the mining <br />would then be managed by the landowner after reclamation. The Thomas Pit permit land is on a <br />private parcel owned by Donna Thompson and Colleen Bryce, who live adjacent to the permit area. In <br />November of 2001, the DMG recalculated the bond required to reclaim the operation which was <br />$25,259. The post-mining land use is a combination of dryland grazing and commercial use in the <br />upper (above river) portion of the area used by the operation. It is also planned that the River be <br />restored to apre-mining condition of natural beauty and hydrologic stability. <br />Since the information required by Ia Plata County and the Colorado Division of Minerals and <br />Geology overlap in many cases, this single document has been produced for both parties. <br />Thomas Pi[ 2/02 <br />
