In training news, Iowa DOT recently posted an update to the agency’s popular Winter Operations Training video series. The new series includes 13 videos on topics such as plowing techniques, preseason preparation, and how deicing chemicals work.

Save the date! The Pacific Northwest Snowfighters will hold their 2020 conference on June 2 and 3 in Portland, Oregon. For details on past conferences, see the PNS website.

Other upcoming events:

• TRB Annual Meeting (January 12-16, Washington, DC)
• APWA Snow Conference (April 19-22, Cleveland, Ohio)
• National Winter Maintenance Peer Exchange (week of September 21, Atlanta)

Hope to see you there!

As temperatures drop, industry magazines are turning their focus to winter maintenance. The October issue of APWA Reporter features an article on Clear Roads training materials:

• Video training on plowing intersections and interchanges
• Video training on using liquids for anti-icing and deicing
• Snowplow Operator and Supervisor Training: 22 customizable instructor-led training modules

As we work to restructure the product submittal process for the Clear Roads Qualified Products List (QPL), we are requesting that no product checklists or samples be submitted until further notice. We hope to be able to start receiving products by October 14. Thanks for your patience as we make this transition.

Please share this information with anyone who may need it. For more information about the Clear Roads QPL, please visit the QPL page.

In September 2020, the National Winter Maintenance Peer Exchange will merge with the quadrennial conference held by TRB’s Winter Maintenance and Surface Transportation Committees to become the 2020 International Road Weather and Winter Maintenance Conference and Peer Exchange. Sponsored by TRB, Aurora, Clear Roads and the Snow and Ice Pooled Fund Cooperative Program (SICOP), this event will be held the week of September 21, 2020, at the Grand Hyatt Atlanta in Buckhead.

For more details, see this announcement from the conference organizers. You can also view presentations and other materials from past peer exchanges on the SICOP website.

For many years, the Qualified Products List (QPL) maintained by the Pacific Northwest Snowfighters association has served as a resource for agencies across the country, identifying deicing chemicals and additives that meet established standards for corrosiveness and impact on the environment. As the QPL continues to grow, Clear Roads will be overseeing the product testing and administration for the list, which is now called the Clear Roads QPL. For an updated version of the CR QPL and a Letter to Vendors about the transition, visit the Clear Roads QPL page.

The Clear Roads Technical Advisory Committee met April 16-18 in Indianapolis to select research projects for 2019 funding. The following projects were selected:

• Expanding Brine Recipes and Their Use
• Synthesis: Retention and Recruitment of Highway Maintenance Workers
• Comparison of Performance of Prewet Road Salt Distributed by Traditional Chain Conveyor Spreader vs. Auger-Driven Slurry Spreader
• Measuring the Efficiencies of Tow/Wing Plows
• Specifications for Automated Snowplow Route Optimization

More information about these projects is available in the 2019 All Proposed Projects summary.
