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