We have tried to follow the order of questions in each <br />response. <br />Colorado Division of Parks and Outdoor Recreation <br />l.a. The Park headquarters is located from 1 to 2 miles from the <br />& b. operation. The new park headquarters will be located on <br />Route 83 north of Cherry Creek on ground that is 300 to 400 <br />feet lower than the quarry. Since the operation is <br />depressed into the upland area, the stockpiles and material <br />processing plant will not be visible. <br />l.c Dust is regulated by the Colorado Department of Health and <br />will require a fugitive dust permit for on -site operations <br />as well as permits for all equipment. <br />l.d The mining plan does not allow pushing excess rock or <br />overburden over the hillside. The mining plan leaves a rim <br />of undisturbed land (100'wide) around the edge of the <br />property which will also help hide any equipment and <br />stockpiles. <br />2.a. The blasting plan calls for use of small explosive charges <br />to minimize noise. The present Hallett operation uses this <br />technique on their present quarry on the outskirts of Castle <br />Rock. There have been no known complaints about this <br />operation and many people in the area are surprised there is <br />even a quarry located in the general vicinity because of the <br />low noise impact. Several county sheriff departments use <br />the existing Hallett Quarry for training officers in <br />explosives handling and for detonating recovered bombs. <br />These blasts have been audible. <br />11990 Grant Street Suite 410 Denver, Colorado 80233 452 -6611 <br />
