be reexamining the entire issue, and there may or may not be changes. <br /> <br /> The motion passed unanimously, 8:0. <br /> <br />B. WORK SESSION: Resolution 4826 Adopting Snow and Ice Removal Policies and Repealing <br /> Resolution 4278 <br /> <br />Jeff Lankston of the Public Works Department's Maintenance Division joined the council for the item. <br />Mr. Lankston recalled that the council adopted a resolution the previous year allowing the use of de-icers <br />and anti-icers for a period of time to allow the City to experiment with their use. The council requested <br />that staff continue to examine the environmental issues associated with the use of the deicers and anti- <br />icers, and return with information on their trial use before April 2005. <br /> <br />Mr. Lankston reviewed the City's use of de-icers and anti-icers, noting that de-icing products had been <br />used five times on City transportation facilities since December 2004. He said the product being used, <br />calcium magnesium acetate (CMA), worked very well. It was effective for a period of several days, which <br />avoided the need for repeated daily sanding applications at one-sixth the cost. <br /> <br /> Mr. Lankston briefly reviewed the results of the City's research regarding the use of de-icers and anti- <br /> icers, noting that information was provided in the council packets and copies of the two reports were in <br /> the council office. In regard to CMA, the literature indicated a concern with biological oxygen demand <br /> (BOD) if placed in high quantities in a waterway. However, the literature indicated that the concentra- <br /> tions being used on roadways did not create problems with BOD, even with ditches adjacent to roadways. <br /> Mr. Lankston believed there were no environmental ramifications from the use of the product on City <br /> streets. <br /> <br /> Mr. Lankston spoke to the issue of vehicle corrosion, indicating that was not an issue in regard to the use <br /> of CMA. <br /> <br /> Mr. Lankston noted that the council approved the use of magnesium chloride but staff had not used that <br /> product on the streets. A Colorado study had examined the product's impact and concluded that the <br /> chloride in the material could damage vegetation close to the road in sufficient strong concentrations, and <br /> trace metals in the product should be restricted. However, the study also concluded the product was <br /> unlikely to cause or contribute to environmental damage greater than 20 yards beyond the roadway. The <br /> City of Boulder had been using the product for many years and extensive water testing indicated no <br /> significant impacts to water quality or aquatic life. He noted that most of Eugene's snow routes had curbs <br /> and gutters to limit the product's contact with the vegetation and it would be diluted to a level of 640:1 <br /> before it reached a catch basin and was further diluted. <br /> <br /> Mr. Lankston said staff proposed only to use products that met the strict standards set by the Pacific <br /> Northwest Snowfighters, which established specifications for products used in winter maintenance that <br /> emphasize safety, environmental preservation, infrastructure protection, cost-effectiveness, and perform- <br /> ance. He noted that the corrosion levels for magnesium chloride met the organization's specifications. <br /> <br /> Mr. Lankston reviewed the three options before the council: <br /> <br /> MINUTES--Eugene City Council February 28, 2005 Page 4 <br /> Work Session <br /> <br /> <br />
