1. Amend the City's Ice and Snow Removal Policy by repealing Resolution 4278 and replacing it <br /> with a proposed new resolution (see Attachment A). By adopting the proposed new resolution, <br /> anti-icing and de-icing chemicals will be permitted in quantities appropriate for ice and snow <br /> control on streets and staff will be able to move ahead with the purchase of application equip- <br /> ment. <br /> <br /> 2. Adopt the proposed new resolution but amend Section 3 to allow for the use of anti-icers and de- <br /> icers through April 1, 2006. Amending Section 3 would allow for the use of anti-icing and de- <br /> icing agents for an additional year. This option would result in operating inefficiencies as staff <br /> will be unable to purchase equipment for liquid de-icer application and, further, would not realize <br /> the economy of scale in purchasing liquid de-icer due to limited storage capacity: Annual rental <br /> rates are approximately 15percent of the cost of a new liquid applicator. With this option the <br /> City will have spent $3,500 on rental fees over the two-year trial period. <br /> <br /> 3. Allow Resolution 4784 to sunset, at which time Resolution No. 4278 will go back into effect. This <br /> resolution states that the City will not use anti-icing or de-icing chemicals in quantities required <br /> for ice and snow control on streets. De-icing chemicals with corrosion inhibitors may be used in <br /> quantities necessary to keep sand stockpiles and sanding equipment workable. With this option, <br /> maintenance staff is limited to using only plows and sanding rock for providing safe road condi- <br /> tions for the traveling public during winter storms. <br /> <br />Mr. Poling called on the council for questions and comments. <br /> <br />Ms. Taylor expressed concern about the potential impact of de-icers on the vegetation in the street <br />frontage of a house. That did not sound like a negligible effect to her. <br /> <br />Ms. Taylor determined from Mr. Lankston that staff anticipated using magnesium chloride. Mr. Lankston <br />added that CMA was only effective to temperatures above 25 degrees. Magnesium chloride was effective <br />to temperatures of zero degrees and was less expensive than CMA. <br /> <br />Speaking to Ms. Taylor's concern about the impact of the products on vegetation, Mr. Lankston clarified <br />that the Boulder study examined how far from the roadway it took magnesium chloride to get a dilution of <br />500:1, at which point the effects of the material became negligible. The City's dilution before the product <br />reached the catch basin was about 640:1. <br /> <br />Ms. Taylor was concerned about the cumulative effect of the products in question, and about the fact the <br />studies being cited were "somewhat old"; for example, the Boulder study was done in 2002. She wanted <br />to know if the studies considered cumulative effects. The Boulder study mentioned that chloride-free de- <br />icers were not used due to their expense, but she did not think that should be a determining factor. She <br />asked if the costs of chloride-free de-icers had dropped as predicted in the study. Mr. Lankston noted that <br />CMA was a chloride-free de-icer and it was about three times more costly than magnesium chloride. Staff <br />was looking at other chloride-free de-icers and would continue to do so. Several were used with <br />magnesium chloride as an anti-corrosive additive. <br /> <br />Ms. Taylor was not inclined to support the continued use of the chemicals in question. <br /> <br />Mr. Kelly expressed appreciation for the thoroughness of the report and said that the Boulder study gave <br /> <br />MINUTES--Eugene City Council February 28, 2005 Page 5 <br /> Work Session <br /> <br /> <br />
