<br /> <br />In the process of constructing the realigned access road to the new scale, a <br />new detention pond was created. This new pond is much larger (more capacity) <br />than the old one, which has subsequently been filled in. This new pond will <br />accommodate much more site runoff and has thereby reduces our exposure to <br />site runoff as a result of an extreme weather situation. <br />In our continuing effort to improve and become more efficient, we have <br />constructed an overhead aggregate load-out system. This system inc'olo~es new <br />ground conveyors, an elevating conveyor and storage silos. The silos have <br />been erected over the new truck scale. This system saves truck travel around <br />the quarry and loader travel between the many stockpiles "chasing the <br />trucks". This not only reduces fugitive dust generated by the "quarry <br />traffic" but also reduces exhaust emissions as well. <br />Water Turbidity: Water turbidity testing is continuing under the laboratory <br />analysis work of Coors Spectro Chemical Laboratories when applicable. If and <br />when turbidity tests are run, the results are forwarded to the Denver Water <br />Board. Be advised that no testing was done this past year due to the lack of <br />any circumstsnces requiring such testing. There are no new water sources <br />used either for mining or reclamation. Any new sources will be identified <br />upon their use. It is important to note that Asphalt Paving Co. has not <br />received any negative comments regarding water from the Denver Water <br />Department. <br />• As previously reported, Asphalt Paving Co. and the Denver Water Board <br />consummated a water purchase agreement allowing water to be obtained from <br />Upper Long Lake for our activities at Ralston Quarry. A water line from the <br />lake to the crushing and processing areas in the quarry was installed and is <br />in use. This water line allows uninterrupted water acquisition from a <br />completely controlled source. This, in turn, enables Asphalt Paving Co. to <br />insure water distribution throughout the quarry operation. This facility <br />provides complete control of the needed water to operate Ralston Quarry. <br />Air Quality: Asphalt Paving Co. continues to recognize its obligation to <br />comply with the applicable air quality standards and regulations set by the <br />Colorado Air Quality Control Commission. Asphalt Paving Co. holds all <br />appropriate permits which have been issued for its operation and is in <br />compliance with State standards. We have not received any air quality <br />violation notices from any agencies. Our superintendent is instructed to <br />notify Jefferson County if he anticipates any "upset" conditions. <br />Hours of Operation: The hours of operation 6:00 a.m. to 6:00 p.m., Monday <br />through Saturday, with only repair work permitted on Sunday, continues to be <br />the rule of our operations. No complete crusher system has been operated <br />prior to 6:00 a.m. or after 6:00 p.m. All crushers, screening plants and <br />conveyors are of the portable type. All efforts have been made by in-house <br />maintenance personnel to provide our equipment with the latest noise <br />suppression equipment. <br />C J <br />
