<br />• This system will involve new ground conveyors, an elevating <br />conveyor and storage silos. The silos are up and have been erected <br />over the new truck scale. When completed, this system will save <br />truck travel around the quarry and loader travel between the many <br />stockpiles "chasing the trucks". This, in turn, will not only <br />reduce fugitive dust generated by the "quarry traffic" but will <br />also reduce exhaust emissions as a result of less quarry travel. <br />Water Turbidity: Water turbidity testing is continuing under the <br />laboratory analysis work of Coors Spectro Chemical Laboratories <br />when applicable. If and when turbidity tests are run, the results <br />are forwarded to the Denver Water Board. Be advised that no <br />testing was done this past year due to the lack of any <br />circumstances requiring such testing.' There are no new water <br />sources used either for mining or reclamation. Any new sources <br />will be identified upon their use. It is important to note that <br />Asphalt Paving Co. has not received one negative comment regarding <br />water from the Denver water Department. <br />As previously reported, Asphalt Paving Co. and the Denver water <br />Board consummated a water purchase agreement allowing water to be <br />obtained from Upper Long Lake for our activities at Ralston Quarry. <br />A water line from the lake to the crushing and processing areas in <br />the quarry was installed and is in use. This installation is a <br />major improvement. <br />• This water line allows uninterrupted water acquisition from a <br />completely controlled source. This, in turn, enables Asphalt <br />Paving Co. to insure water distribution throughout the quarry <br />operation. This facility now provides complete control of the <br />needed water to operate Ralston 4uarry with an acceptable degree of <br />professionalism as well as the strong, established commitment <br />Asphalt Paving Co. has to Jefferson County. <br />Air Oualit~ Asphalt Paving Co. continues to recognize its <br />obligation to comply with the applicable air quality standards and <br />regulations set by the Colorado Air Quality Control Commission. <br />Asphalt Paving Co. continues to hold all appropriate permits which <br />have been issued for its operation and will work hard toward <br />compliance with State standards. We have not received any air <br />quality violation notices from any agencies. Our superintendent is <br />instructed to notify Jefferson County if he anticipates any "upset" <br />conditions. <br />Hours of Operation: The hours of operation 6:00 a.m. to 6:00 p.m., <br />Monday through Saturday, with only repair work permitted on Sunday, <br />continues to be the rule of our operations. No complete crusher <br />system has been operated prior to 6:00 a.m. or after 6:00 p.m. All <br />crushers, screening plants and conveyors are of the portable type. <br />All efforts have been made by in-house maintenance personnel to <br />equip our equipment with the latest noise reducing suppressant <br />• equipment. <br />~,,,.,,,,~,~. 3 <br />
