MSHA inspections that <br />have revealed high noise levels have been corrected immediately <br />and have been subject to subsequent verifications and compliance <br />with their standards. <br />our blast vibration monitoring consultant has been and continues <br />to be Vibra-Tech Engineers Incorporated. A continuing and <br />effective blast vibration monitoring program is presently being <br />carried out. The resulting data has been analyzed by this <br />independent service and the resulting analysis data continues to <br />be submitted directly to the Denver Water Board by agreement <br />between Asphalt Paving Co. and the Denver Water Board. <br />Asphalt Paving Co. continues to monitor noise levels within its <br />own operation with a Tracoustics SLM-SZA portable sound level <br />meter operated from those instances which are consistent to the <br />operation. As a result, Asphalt Paving Co. has not received a <br />single noise complaint during this past year. <br />To our knowledge, all noise and blasting measurements have not <br />shown any readings exceeding the safety limits required by the <br />Colorado State or federal law. <br />Traffic Routing: The truck trips leaving the quarry site have <br />been split as equally as possible so as not to concentrate truck <br />traffic of any nature upon any location. The truck routing hours <br />• have been regulated through our truck foreman on a daily basis. <br />Our scale house personnel have been instructed to assure <br />themselves that this truck routing is followed. Our position <br />still remains to work closely with the schools, City of Golden, <br />and Jefferson County. We are aware of the conditions set forth <br />in the resolution regarding traffic routing, the hours of <br />restrictions and the percentage of trucks using these highways <br />and continue to maintain a scheduling posture so that these <br />conditions are recognized. Asphalt Paving Co. has continued to <br />employ those same persons as in the past who recognize the <br />importance of the truck routing requirements, specifically the <br />truck foreman and scale weigher. With the improvements to <br />Highway 93, especially in close proximity to our quarry, the <br />increased traffic load as well as the high speed traffic has <br />accommodated our trucking very well. Asphalt Paving Co. <br />continues to monitor our trucking activity as it relates to <br />Highway 93 very closely. We have benefitted from these <br />improvements and continue to take advantage of them in <br />maintaining a controlled, safe operation. Be advised that the <br />average number of trucks per day (on an annual basis) was 75. <br />Mining: As previously addressed in the 1985 report, Asphalt <br />Paving Co. was granted permission for an asphalt plant at some <br />future date, to be located within the boundary provisions of <br />Ralston Quarry. There have been no circumstances to date which <br />• 4 <br />
