Following is a <br /> summary of the work completed for this project. <br /> SGC obtained an Utility Permit from the Colorado Department of Transportation <br /> (CDOT)to install a 24" ADS culvert under Colorado Highway 110. CDOT specified the <br /> use of flowable fill, for backfilling the culvert, as a condition of the utility permit. SGC <br /> agreed and placed the culvert under Hwy.110 according to CDOT specifications. <br /> The culvert was placed to allow gravity drainage of surface runoff from the side-slopes of <br /> Tailings Pond No.4 and from the highway surface. These runoff flows previously <br /> collected along the toe of Tailings Pond No.4 and infiltrated to groundwater, probably <br /> through tailings material, or evaporated. <br />
