The [ile drains are the property of CAMAS Co., Inc. They will either be preserved as is, with a 10' setback from their current location, or [hey will be replaced with new the drains with increased capacity. 4) Concerns about damage to existing structures near the site, and the lack of an engineering evaluation of the area or setback agreement with the landowners The aforementioned condition to the permit preserves the 200' setback required by Rule 6.4.19 in lieu of an adequate slope stability analysis. Should such an analysis be submitted no later than 4p.m. on March 9, 2000, then the setback may be revised in accordance with geotechnica] engineering practices and standards. 5) Concems about the groundwater and surface water flows from the north, should the drainage tiles be disturbed; also a concern that the drainage agreement will not be honored. The Technical Revision to this application submitted on January 14, 2000, removed 15 acres from the proposed excavation azea, and the drainage tiles aze to be preserved as there are, as well as improved in some areas. No groundwater will be exposed at the site prior to the approval of an augmentation plan or temporary substitute supply plan by the Office of the State Engineer (OSE) and the approval of clay lining specifications by DMG. 6) Concems about the groundwater and surface water flows if the ponds are lined, and the subsurface drainage area is reduced to a corridor through the residential area. A groundwater monitoring plan has been approved, with reporting triggers and mitigation actions to be taken should the groundwater levels rise beyond 18" in the monitoring wells. Five of the ponds aze to be lined, leaving the other two open to subsurface flows. 7) Concerns regazding the possible narrowing of the 100-year flood plain, and subsequent flooding. Setbacks from the Cache le Poudre have been set for summer and winter conditions, along with backfilling requirements within 200' of the river. No narrowing of the floodplain is expected under these conditions. 8) Concerns that the stockpiling of materials near the river may change the course of the river. All product stockpiles will be stored in the process azea, outside the 100-year floodplain. 9) Concems that the re-seeding will not be done in a timely fashion, and that weeds will encroach upon the site and surrounding areas. Please verify that only two acres at a time will be in the process of preparing for re-seeding each year, and that the rest of the 34 disturbed acres will either be actively worked or part of the processing facilities. This statement was confirmed by the Applicant.
