(Page 2) MINE ID N OR PROSPECTING ID N M-1989-029 INSPECTION DATE 3/26/00 INSPECTOR'S INITIALS CLEr Tlris inspection was done in response to a complaint received on March ld, 2000, by the Division. The complaint included a specific list of problems, outlined below, as well as photographs with several more problems mentioned. 1) Dust probh:ms The day of the inspection was overcast, and it had rained the night before, so this was not the optimum time to observe dust activity. However, from what was observed during the tour of the site, it appeared [hat [he stockpiles in the processing area were sufficiently contained and that no dust was blowing away from the main industrial area. Some dust was observed rising from the m;tin excavation area; the stockpiles and excavation area are watered 3 to 4 times a day via water truck. 2) Odor probl~:ms As was merttio~ed previously, it had rained the day prior tc the inspection, so it was unlikely a significant odor problem could be observes'. Mark Helm mentioned that an adjacent lot contains a wck yard, with fifteen or so vehicles stored on-site, which could also tie at least partially responsible for any odor problems. CAMAS is currently operating within the parameters of the Colorado Department of Public Health and the Environment's air emissions permit. 3) Wildlife: (a) that de watering had killed well over 100 bin.-12in. cottonwood trees off the permitted area. At this time, none of the trees in the adjacent area have much cover on them, however, many do display signs of budding and life. While some trees within the permit area may have died due to either old age or from the effects of dewatering, no significant stands of dead trees were noted during this inspection. However, a second inspection will be made later this year to follow-u.p on this issue, when a better comparison can be made between health and dying trees. It would be appreciated if the complainant could specify the exact area where the die-off is occurring, so that DM ~ can document the occurrence and ask that appropriate mitigation measures be taken. (b) that de•watering is done with buried asphalt and concrete submersed around the dewatering pumps, which discharge directly to the St. Vrain river. An area where concrete which has been slated for recycling is being stored, has become a secondary holding pond for runoff from the sire. Water from the process and stockpile areas was originally pumped either into the St. Vtain (in accordance with the NPDE;i permit) or to the completed lake on the east side of the site. As a temporary measure, this water was placed in the shallow depression which abuts the concrete storage area. When the water level rises high enough, the water discharges through a pipe under the adjacent road into the constructed lake. This is not in the current permit mining plan. While there is no asphalt in this storage area, and the concrete has been cured (thus decreasing the likelihood of any contamination to the water), the permit must be revised to either include these measures for water and concrete storage, or the water must be siphoned over to the approved lake for pertranen[ storage. The concrete storage azea would then not be used as a water containment area in the future. (See PBl) (c) that wildlife in the area are slowly losing their habitat. Many ducks, geese, and other biris were.observed in the area. The l00' setback from the property line near the St.Vrain river is still being observed. lVo other effects an the local wildlife could be pin-pointed. However, this inspection report will be forwarded on to the Division of Wildlife, so that they will be aware of concems expressed about the site. 4) Property va.ues The Division of Minerals and Geology does not have jurisdiction over property value concems. All land-use questions and zoning problems should be directed to the County Planning and Zoning department, which can analyze whether mining is an appropriate industry to be developed in this area.
