All gravel currently being used for the operations cmcrete facilities is being itported to the site. Most of the gravel cars fro Ouray Cowty or a site near Naturita, Colorado. Sor of the gravel is a recycled product containing several types of crushed rack including recycled asphalt. The operator had itported sar taterial that then had ezcavated fro one of their construction project sites in Telluride. This taterial, which consisted Costly of a red rak with sae concrete and asphalt content, had been deposited within their pit area. The Division will follow-up this inspection by contacting the Colorado Departrnt of Health to solicit their ruling a the classification of this tateria! as a solid waste and obtain their guidance related to the proper handling of this taterial. Telluride Gravel will be notified of the Division's findings. The new office and waste oil facilities, penitted earlier this year, have been installed and appear to be in carpliance with their approved design plans. The north wall of the waste oil containrnt structure was constructed approzitately 6 ft. tall instead of the 2.5 ft. designed heig5t.
