Commercial Asphalt Page 2 <br /> 6/27/95 continued ... <br /> • Issues <br /> Dust <br /> Changes to this operation, since the last renewal, to control dust include <br /> paving the entrance to the site and buying a sweeper attachment for a Bobcat <br /> to clean the dust off of the hard surface drive and adjacent streets. <br /> Commercial Asphalt also continues to water as needed to control dust. <br /> Sedimentation <br /> Previously, there was a sedimentation problem to a pond in the southeast <br /> corner of the intersection of Highway 169 and County Road 33. Sediment <br /> from the Commercial Asphalt site was running to this pond and filling it in. <br /> Enlarging the sedimentation pond on Commercial Asphalt's site, appears to <br /> have alleviated this situation. The sweeper previously mentioned will also <br /> help. Staff feels this issue is resolved. <br /> Noise <br /> When Commercial Asphalt first started up, the city received complaints <br /> regarding noise levels from the plant. Adjustments to the blower fan for the <br /> • hot mix plant and placement of stockpiles apparently eliminated these <br /> problems. Staff has not received any complaints regarding noise for several <br /> years. <br /> Odor <br /> Staff feels that odor is the one true outstanding issue. To alleviate problems <br /> with odor, Commercial Asphalt has raised their stack height to help dissipate <br /> odor, and reduced the amount of recycled materials used during weather <br /> inversions. They have also made their phone number available for people <br /> with complaints. <br /> As of the date of this memo, Commercial Asphalt has received complaint <br /> regarding odor from the following residents: <br /> 1. Brenda Bunker, on May 11, 1995, at approximately 2:30 p.m. Ms. <br /> Bunker lives on the east side of Highway 169. It was speculated that <br /> the odor was due to the plant just starting up at the time of the <br /> complaint. Once the plant reached full temperature, the complainant <br /> was called back and she indicated the odor had disappeared. <br /> • 2. Dave Munter, on May 16, 1995. Again, at the time of the complaint <br /> the plant was just being started up. It was discovered that the <br /> C-27connn/bz/stever <br />
