PERMIT #: M-1977-345 <br />INSPECTOR'S INITIALS: ECS <br />INSPECTION DATE: January 13, 2016 <br />OBSERVATIONS <br />This was an inspection for a 110c sandstone quarry operation conducted by Eric Scott and Wally Erickson of <br />DRMS for the Boettcher Sandstone site at the request of the permittee (Holcim). DRMS accompanied <br />permittee representative Michael Toelle to the site at approximately 1000 and toured the site with him. <br />Holcim requested this inspection for DRMS to review and approve the final reclamation earthwork that was <br />approved in November of 2015 as TR01. Because mining was never completed at the site, TRO1 was <br />submitted to revise the initial reclamation plan which was no longer feasible due to a lack of unconsolidated <br />waste. TRO1 proposed utilizing all available material at the site to minimize the steeply sloped area at the <br />north end of the site left behind from prior mining (approx. 1:1), and blend the disturbed area to integrate <br />into the surrounding landscape as well as possible. <br />The final reclamation configuration has resulted in a gradual slope up from the pit floor of approximately 2:1 <br />with a 20-30 foot bench at the top. This bench forms the base of the existing stable 1:1 slope. This steeper, <br />but stable, slope is approximately 40-50 feet in width, and extends for a linear distance of approximately 250 <br />feet at the northwest portion of the disturbance. <br />DRMS has requested that the existing 1-3 foot high unconsolidated soils lip at the top of the steeper slope be <br />reduced to blend with the remaining slope. When this is completed, DRMS feels that the sloping and grading <br />portion of the reclamation at this site will be acceptable given that the current slopes are vegetating and <br />stable, and that there is no more unconsolidated material available on site to further reduce the remaining <br />slope in this area without increasing the overall disturbance. <br />The site is located within the steeply dipping "hogback" area of the front -range north of Fort Collins. The <br />native terrain varies considerably in the area from vertical bedrock outcrops to rolling vegetated areas of <br />rapidly changing slope. DRMS believes that the current reclamation will be stable and blend very well with the <br />surrounding pre -mining topography of the area. Holcim stated that they intend to blend the upper <br />unconsolidated "lip" at the top of the slope immediately, and seed the site for final reclamation in the spring <br />of 2016. <br />No other issues were noted during this inspection. <br />Inspection Contact Address <br />Mike Toelle <br />Holcim (US) Inc. <br />3500 Highway 120 <br />Florence, CO 81226 <br />Page 2 of 2 <br />
