Azurite, Inc. <br />10001 CR 12 P.O. Box 338 <br />Cotopaxi, Colorado 81223 <br />719-942-4178 <br />Apri124, 2003 <br />State of Colorado <br />Division of Minerals and Geology <br />1313 Sherman Street Room 215 <br />Denver, CO 80203 <br />RE: ANNUAL REPORT PERMIT NO. M-1977-247, G-P GYPSUM CORPORATION <br />All contact information is current as listed on the Annual Fee and Report Request form. This <br />operation is in closure status, the &rst year of a five year extension of the pernut as approved by <br />the Mined Land Reclamation Boazd September 27, 2002. The extension was granted to give the <br />mine operator time to continue vegetative establishment in azeas where grass and shrub cover was <br />selected as final reclamation. <br />2002 reclamation operations included the completion of equipment removal, concrete foundation <br />burial, re-grading, and seeding/mulching operations in the former crusher site azea, a five acre <br />azea located in the southern part of the affected land area as shown on the site map. A sixteen <br />species grass, forbe, and shrub seed mix was broadcast seeded at 30#/acre followed by 50#/acre <br />inorganic Nitrogen and 80#/acre inorganic Phosphorous and straw mulch applied at 3000#/acre. <br />Storm water management systems were completed during the later part of the season, with the <br />construction of the major sediment control structure located at the entrance to the former crusher <br />site. Work in this azea included the completion of a spillway device for the sediment pond which <br />will feed the mane storm ditch exiting the former crusher site. This storm ditch feeds the final <br />sediment pond structure located at the southern end of the site located on the site map. The <br />spillway structure was built using a geotextile fabric installed in the drainage channel, covered <br />with a minimum four inches of soil, and armored with 6-8 inch rip-rap at the crest of the spillway <br />structure. Eighty feet of geotextile was installed at the spillway point and two hundred and <br />twenty feet of geotextile was installed at the southwestern comer of the crusher site, where storm <br />related surface water flows might overflow sediment basins located duectly above the main <br />sediment pond azea and migrate into the main sediment control azea. All geotextile fabrics were <br />keyed into the untying soils via trenching along both mazgins of the fabric (I 5 feet wide) and <br />every thirty feet ofran ofchannel as lined. Seeding and mulching operations followed the <br />covering of fabric with 4-6 inches of soil Additional seeding and mulching occurred in several <br />azeas including along the main access road above the former crusher site leading to highwall azeas <br />and southern portions of the former mine site. Seeding and mulching operations also were <br />performed along the southern toe ofthe Gillespsie Hill waste dump and over small (<1/4 acre) <br />
