<br /> <br />Commercial Asphalt <br />April 18, 1994 <br /> <br />Page 3 <br /> <br />e <br /> <br />WATER QUALITY <br /> <br />Adjacent to the east side of Highway 169, opposite Commercial Asphalt's <br />facility, is a pond that is receiving sediment from run-off. Staff has inspected <br />the situation and feels the pond is receiving sediment from the acceleration <br />lane on the west side of Highway 169, via a culvert under the Highway. The <br />following is a list of possible solutions to this situation: <br /> <br />1. Commercial Asphalt could dig a bigger storm water retention pond on <br />their site (see attached site plan). The berm on the north side of this <br />retention pond could also be built up to avoid run-off entering the <br />highway ditch during heavy rainfall events. <br /> <br />2. Commercial Asphalt's access road could be paved and moved farther to <br />the west to reduce the amount of material finding its way to the <br />acceleration land. <br /> <br />3. Commercial Asphalt indicated that they have a bobcat sweeper and <br />will clean the acceleration lane more often. <br /> <br />e <br /> <br />4. <br /> <br />Silt fencing in the highway ditch prior to the culvert could be used to <br />help filter sediment. This would take MnDot permission. <br /> <br />5. The ditch on the west side of the highway could be made deeper and <br />vegetation planted to help filter the sediment. This also would take <br />MnDot permission. <br /> <br />RECOMMENDATION <br /> <br />The Planning Commission is recommending approval of a one year renewal <br />of this permit with the 14 stipulations placed on this operation during its <br />1992 renewal and two additional stipulations (#'s 15 & 16): <br /> <br />1. THAT A MAXIMUM OF 30% RECYCLED ASPHALT CAN BE USED <br />IN THE OPERATION IN ORDER TO CONTROL ODOR. IF <br />WEATHER CONDITIONS MAKE ODOR TOO NOTICEABLE, THE <br />OPERATOR MUST TEMPORARILY REDUCE THE PERCENTAGE <br />OF RECYCLED ASPHALT IN THEIR OPERATION UNTIL <br />ATMOSPHERIC CONDITIONS ALLOW THE 30% LEVEL TO <br />CONTINUE. <br /> <br />e <br /> <br />cc-aspha.council <br />
