| *Brine holding tanks: Collection of first flush (high chloride concentration) melt water runoff from a salt induced snowmelt (as opposed to rain and temperature induced snowmelt) has the potential to be beneficial if captured and reused as an anti-icing or pre wetting solution. In order to collect the first flush runoff, an electronically actuated valve controlled by an electrical conductivity sensor would be installed at the desired conveyance point to divert and collect the high chloride concentration runoff into a brine holding tank. The brine holding tank would be placed below ground and a pump could be connected to pump the brine solution into an anti-icing tank or directly used to pre-wet rock salt. <ref>LSRCA. 2015.Parking Lot Design Guidelines to Promote Salt Reduction.

| | Contracts for snow and ice management on private parking lots are typically oriented towards ensuring that plowing and salting promotes safe conditions throughout the winter, and that interruptions to regular business operations are kept to a minimum. The first thought of many people may be that applying more salt is safer for their patrons and workers but, applying more than is necessary not only harms the environment, as previously mentioned but also shortens the life of parking lot surfaces and can accelerate the process of corrosion of nearby buildings or transportation infrastructure on site, not to mention the extra cost of unnecessary road salt application. Property owners, businesses and contractors have control over how much salt is applied through their snow and ice management contracts, and the diligence with which they manage and oversee these contracts. The [https://sustainabletechnologies.ca/app/uploads/2019/06/Procurement-Guidance-Parking-Lot-Snow-and-Ice-Mgmt.pdf Procurement Guidance for Parking Lot Snow and Ice Management] by STEP <ref>STEP. 2019. Procurement Guidance for Parking Lot Snow and Ice Management. Version 2.0 https://sustainabletechnologies.ca/app/uploads/2019/06/Procurement-Guidance-Parking-Lot-Snow-and-Ice-Mgmt.pdf</ref> describes various clauses and conditions that can be considered by these groups to be included in contracts to promote the responsible use of road salts. A summary of the measures are provided in with estimates of the impact on salt use, and the potential influence these may have on contract costs. |

| | **Businesses can help reduce over-salting by ensuring that rock salt during the winter months is applied responsibly on parking lots and walkways. An easy way to do this is by ensuring that your snow and ice maintenance contract includes provisions requesting that industry best practices be employed and that associated operators are adequately trained. Some BMP for procurement for rock salt application services include: |
