Gordon Benton of Holcim (US) Inc., Bill <br />Schenderlein and Cali Baueu of Applegate Group, Inc. were present during the inspection. <br />The Boettcher Gypsum Quarry is located 9 miles north of Buckeye in Larimer County. A 112 <br />Mining and Reclamation Permit was issued to Ideal Basic Industries, Inc. on October 10, <br />1978 for a permit area of 110 acres. The permit was transferred to Holnam, Inc. on March <br />23, 1990 and then to Holcim (US), Inc. April 14, 2003. The Division currently holds a <br />financial warranty in the amount of $38,000.00. <br />The site has been in temporary cessation status (TC) since May 23, 1996. The gypsum <br />occurs on an outcrop and is mined in 12-16 foot thick beds. The west side of the quarry <br />has been reclaimed to 3h:ly slopes. A rock pile at the base of the slope will need to be <br />removed upon final reclamation of the site. It does not appear that this area has been <br />revegetated to date. <br />On the east side of the quarry mining occurred on the exposed gypsum outcrop. Any <br />remaining benches and highwalls will need to be reclaimed. The reclamation plan states <br />that contours of the quarries will be smoothed to blend with surrounding terrain and break <br />down any walls left to a slope not exceeding 3h:iv. Any topsoil encountered during the <br />mining operations will be stockpiled and then re-spread on the floors of the quarries or <br />other areas of low erosion potential and seeded with native grasses. The approved seed <br />mixture consists of Little bluestem (5 lbs PLS/acre), Side-oats grama (6 lbs. PLS/acre), <br />Indian ricegrass (8 lbs PLS/acre) and True mountain mahogany (y, lbs. PLS/acre). <br />I & 8 Contact Address <br />NAME Gordon Benton <br />OPERATOR <br />STREET <br />CITY/STATE/ZIP <br />Holcim (US), Inc. <br />PO Box 1548 <br />LaPorte, CO 80535 <br />^ CE <br />^ BL <br />^ FS <br />^ HW <br />^ HMWMD (CH) <br />^ SE <br />~ WQCD (CH) <br />Cc: Carl Mount; DRMS <br />Bill Schenderlein; Applegate Group, Inc. <br />
