STEP released a technical brief on the alternatives to municipalities across Canada using salt as their primary deicer agent in winter, which has significant impacts (corrosion of infrastructure and other metal structures such as railings and doorways; damage to vehicles; contamination of surface and groundwater; impacts to roadside vegetation; increased wildlife collision rates; and large amounts of product waste due to blowing or bouncing off roadways). Numerous alternatives were tested to see what could feasibly replace the overreliance on rock salt which at a high-level include: chloride deicers, acetate deicers, and agricultural by-products (organics). To read more about the benefits, drawbacks, cost estimates and lowest working temperature for a given deicing agent, click the button above.

LSRCA staff highlight in this brief about some BMPs have been developed specifically for winter maintenance in parking lots. Along with recommendations around the proper use and calibration of equipment, many of these practices relate to plowing the lot and walkways before applying salt, and applying the recommended amount of salt for the conditions. Several studies have been conducted, by industry and academia, to determine what the “right” amount is, and, while “proper” application can vary depending on temperature and conditions. This report talks about main considerations contractors face in maintaining parking lots in winter:
*what application rate should be used?
*what is the level of service expected by the client, for which the bare pavement return time is a common measure?
In order to better understand these questions; in 2017 the LSRCA obtained a friction tester, with a goal of quantifying the effectiveness of various practices and salt application rates. LSRCA’s friction testing showed that bare pavement is safest, as it has the highest friction value, and that the over-application of salt does not translate to safer conditions.
