April 27, 1989 <br /> President <br /> Yahara Materials Inc. <br /> 6117 County Trunk K, Route 1 <br /> Waunakee, WI 53597 <br /> Dear Mr. /Ms. President: <br /> We are residents of the home at 6633 Greenbriar Road which is <br /> near your sand and gravel pit off Highway 12 just north of <br /> Middleton. On Monday April 17, 1989 in the course of your <br /> operations an improperly controlled blast caused a <br /> significant shock wave in the area. <br /> My wife was home at the time and at 11: 55 A. M. was in our <br /> family room. She heard a tremendous noise as the house and <br /> it' s beams recoiled from the shock. When she looked up at <br /> the ceiling, she noticed the entire roof structure shift to <br /> the south 6 inches and then return to near it' s original <br /> position. This requires no small amount of force because the <br /> roof is framed in oak 8X8' s and has 30 tons of concrete roof <br /> tile holding it down. <br /> She was so frightened by the sight that she turned and ran <br /> toward the nearest exit along with our equally frightened <br /> dog. My wife has suffered considerable mental turmoil due to <br /> that incident and with subsequent smaller more controlled <br /> blasts that occurred after the complaints were made to your <br /> organization. <br /> We registered a complaint to Yahara on the same day of the <br /> blast and on following Wednesday informed you that the <br /> blasting was still noticeable. On Friday after the third t <br /> blast of that week she contacted the Dane County Sheriff' s <br /> Department and registered a formal complaint. She <br /> additionally notified the Department of Industry, Labor and <br /> Human Relations and notified the Mine Safety Bureau Director <br /> of the incident. Additionally Madison Gas and Electric was <br /> requested to make and inspection in the area to determine if <br /> any leaks had occurred due to the ground shock. <br /> A significant amount of damage has resulted, in our opinion, <br /> to our home as a result of this and other blasts. These <br /> include a crack in the brick exterior, a cracked window, <br /> numerous cracks and bulges in the drywall, beam dislocation <br /> from joints, separations from the posts and interior stud <br /> walls and a coincidental simultaneous burn out of <br /> approximately ten light bulbs. <br /> 1 <br />
