MINE ID # OR PROSPECTING ID#: M-1977-348 PAGE: 2 <br />INSPECTION DATE: 8-19-08 INSPECTOR'S INITIALS: ACS <br />Full-scale reclamation of the quarries and spoil ridges at the <br />Boettcher Quarry was completed during 2005 and 2006. This included <br />highwall reduction, backfilling, grading, spreading of plant growth <br />soil including imported topsoil, and seeding. Backfilled and graded <br />slopes were measured at numerous locations during this inspection, and <br />all measured slopes were less than 2H:1V. The outslope of the <br />demolition debris fill was measured to be 17 degrees, or 3H:1V. <br />Revegetation of most of the reclaimed areas has progressed very well. <br />The E-1 Quarry and some other areas at the south end of the site are <br />more weedy, with kochia predominating. Presence of kochia in the early <br />succession of vegetation establishment is not problematic, and it is <br />recommended that evaluation of these areas occur again in 2009 when it <br />is anticipated that some of the seeded grasses will better present <br />themselves. <br />There are small areas of ponded water in the bottom of several of the <br />reclaimed quarries. The State Engineer requires that when water is <br />stored in excavated areas that evidence be provided that the water is <br />properly permitted or decreed, or that provisions be made to release <br />captured water within 72 hours of impoundment. Holcim must contact the <br />State Engineer's Office to determine what options are available for <br />dealing with the captured water and provide the DRMS with documentation <br />of resolution to this matter. <br />The DRMS files contain analytical results for ground water sampling <br />from the four wells located below the CKD disposal site through the <br />sampling conducted in July 2000. Holcim must provide data from <br />subsequent sampling and analysis. Once all of the information is in to <br />DRMS, it will be reviewed to determine if any additional actions are <br />necessary for the protection of ground water quality at this site. <br />The reclamation conducted by Holcim in the 5-mile long Boettcher is <br />impressive and very well done. Vegetation is not yet established in <br />all reclaimed areas, but progress toward full establishment is well <br />underway. The surface and ground water issues discussed above must be <br />addressed in the near term so that bond release will not be held up <br />once the vegetation is established. <br />cc: Shannon Johnson, SEO <br />Inspection & Enforcement Contact Address <br />NAME Mike Toelle <br />OPERATOR Holcim (US) Inc. <br />STREET 3500 Highway 120 <br />CITY/STATE/ZIP Florence, CO 81226
