Case #9: <br /> <br />Status Conditional Use Permit for Asphalt Mix Plant; Case of Commercial <br />Asphalt <br /> <br />Community Development Director Frolik stated that at Citizen Input at City Council meetings on <br />October 22 and November 12, 2002, City Council received a complaint on each date fi'om a <br />resident regarding bad odors emanating from the Commercial Asphalt plant located at 14100 <br />Basalt St. N.W. The November 26, 2002, Council agenda included an extensive case regarding <br />the history of the plant and its status with respect to current environmental regulations. On <br />November 26, 2002, City Council tabled the matter for 60 days and directed Staff to gather <br />additional information for Council to use in making a determination regarding how to proceed in <br />the Commercial Asphalt case. Commercial Asphalt plant operations shut down for the season <br />last November. Needless to say, no new complaints have been received at the City since last <br />November. Last November, Mike Caron of Commercial Asphalt made a commitment last <br />November to explore ways to resolve the odor issues. Staff has been in touch with Mr. Caron. <br />Commercial Asphalt has offered up a couple of options. First, the plant was designed in a way <br />that they can raise the stack height another 30-40 feet. Raising the stack height provides more <br />time and area for odors to dissipate before reaching ground level. Another option is that this <br />spring the plant manager will erect a sign at the unloading area establishing that all deliveries <br />must contain the odor mitigating additive and there will be regular monitoring for compliance. <br />In addition, the additive supplier has suggested that the ratio of additive to asphalt cement should <br />be 1 gallon per truckload, especially for modified asphalt cements, which are more odorous. <br /> <br />Mike Caron, Tiller Corporation, stated that they would like to make a strong effort this spring to <br />make sure the right amount of odor additives are being used. <br /> <br />Councihnember Elvig inquired if the additive would eliminate the smell. <br /> <br />Mr. Caron explained that the additive masks the smell as well as eliminating some of the odor so <br />that the asphalt smell should not be so noticeable. <br /> <br />Councihnember Kurak stated that the City has received many complaints from Mr. Hamilton, <br />which concerns her. <br /> <br />Councilmember Cook inquired if there is health affects because of what is being dispersed and if <br />they mask the smell is there still those health concerns. <br /> <br />Mr. Caron replied that that is not the case at all. He explained that their plant is regulated by <br />pollution control and the EPA has looked into the safety of asphalt plants. <br /> <br />Councihnember Pearson inquired if Mr. Caron has received complaints at any of their other <br />plants. <br /> <br />Mr. Caron replied that they did have similar complaints at their Scandia plant. They have <br />introduced the additive and increased the height of the smokestack at that plant and since that <br />time they have not received any complaints. <br /> <br />City Council/March 11, 2003 <br /> Page 16 of 23 <br /> <br /> <br />
