We are adamantly opposed m We eonstrwction and operation oftbis or ae4` other mixing facility <br />of this type is this area. We have had dbect experieaco withthe impacts associated with flu: opetatiori of <br />the Albert Frei dt Sons Quarry on IJS b in Clear Creek Cegyon. Nono ofihe regulations associated with <br />the operation of this facility have peen enforced hl'the State of Colorado, setting a very poor example of <br />ruck mining is this sensitive region. As such, we request that DMG delay a decision to issue a mining <br />penmt until the following issues, at a minimum, xis fully Ronsiderod sad addressed. <br />With rasped to the quarry application we have the following specific comments: <br />Page 10 BlastiagPrmednres <br />Both private and public stnrctuies mast be protected from the impacts of blasting androc7c movement. <br />The most stringent OSM,179 Buroan ofMines, or other relevant ground vibration standards must be <br />adhered to.
