City Council Minutes May 21, 1990 Page 12 e therefore, the odors may be stronger, however, a higher stack may solve this problem. Councilmember Kropuenske questioned stipulation #13 which allowed the plant to operate seven days a week. He stated that he was concerned with summer traffic on Highway 169 and that a 7:00 a.m. to 2:00 a.m. time limit should be put on the temporary asphalt plant for Sundays. Dick Peterson explained that the Highway Department dictates when the roads will be worked on. He stated that the commuters wants the construction work to be done on weekends and nights, therefore, the plant must be able to operate during those times. Councilmember Kropuenske stated that he would then like to see an acceleration lane south on Highway 169 off of County Road 33. He stated that there has been a continual traffic problem in that area. Pat Klaers, Ci ty Administrator, stated that perhaps the Commercial Asphalt Company may be asked to contribute to the cost of constructing the acceleration lane. Mayor Tralle stated that this should be addressed as an addi tional stipulation. Dick Peterson questioned how the City would equitably divide the cost of the acceleration lane. He would like to see other gravel companies equally share the cost.
