| Entity | Implementation Period | Main Actions Implemented | Salt Reduction | Cost Savings |
|---|---|---|---|---|
| University of Minnesota, Twin Cities | Start 2006 | Began making salt brine and anti-icing and adopted several other salt reduction BMPs. | 48% |
|
| City of Waconia | Start 2010 | Switch from 1:1 sand:salt to straight salt & liquid anti-icing; calibration; equipment changes; use of air and pavement temperatures. | Switch from 1:1 sand:salt to straight salt & liquid anti-icing; calibration; equipment changes; use of air and pavement temperatures. | $8,600 yearly cost savings ($1.80 per lane-mile) |
| City of Prior Lake | 2003-2010 | Upgrade to precision controllers & sanders; anti-icing & pre-wetting; use of ground temperatures, best available weather data; on-site pre-mix liquid & bulk-ingredient storage, mixing & transfer equipment; staff education. | 42% | $2,000 per event estimated cost savings; 20 – 40 mg/L decrease in receiving-water chloride (liquid app-only watershed) |
| City of Richfield | Start 2010 | All-staff Training*; yearly sander calibration; use of low-pavement-temp de-icers; road crown-only application; minor-arterial-road policy adjustments | > 50% |
|
| Rice Creek Watershed District Cities | 2012-2013 | Staff training; purchased shared anti-icing equipment | 32% | $26,400 in one winter |
| City of Cottage Grove | 2011-2012 | Staff training | Not available | $40,000 in one winter |
| City of Shoreview | Start 2006 | Stopped using a salt/sand mixture and moved on with straight salt; set up all its large plow trucks with state of the art salt spreading controls, pre-wetting tanks and controls and pavement sensors; use of calcium chloride in the pre-wetting tanks reduced the amount of rock salt as well; all applicators and supervisors annually attend *Training; crews attend an annual snowplow meeting to review procedures and talk about salt use and conservation methods; trucks set up for anti-icing main roads with calcium chloride. | 44% since 2006 | $24,468 in 2014 |
| City of Eagan | Start 2005 | Moved from a 50/50 salt/sand mix to straight salt; eliminated purchase of safety grit; EPOKE winter chemical application technology; use AVL; pre-wet at spinner | Not available | $70,000 annual savings |
| Joe’s Lawn & Snow, Minneapolis | Start 2013-2014 | Owner & staff Training*; purchase of new spreader, temperature sensors; equipment calibration; use of temperature data; on-going experimentation. | 50% | $770 estimated cost savings in 2014 - Expected to use 20 tons, only use 9 tons |
