Using the right salt brine mix to combat snow and ice can be tricky. How do you come up with a mixture that works at low temperatures while remaining cost-effective? Two agencies will discuss their blending experiments during The Ins and Outs of Blending Salt Brine (Sunday, Sept. 10, 2 to 2:50 p.m.). Mark DeVries, superintendent for the McHenry, Ill., County Division of Transportation will discuss how his agency tinkered with different chemicals, ultimately creating a three-deicer blend called Supermix and winning a 2006 Technical Innovation Award from APWA's Chicago Metro Chapter. “The system takes operator error out of the mix, and we reduced filling time in our trucks,” he says.
Joining in the discussion will be Bret Hodne, superintendent of the department of public works in West Des Moines, Iowa; he will relate how his agency—inspired by McHenry's success—has experimented with blending and using computerized controls. “With the reduced or tight budgets that many agencies have to work with, finding more economical ways to effectively handle winter storms has some real merit,” says Hodne.

From the Shovel to the Plow
For agencies finding it hard to wrestle with staffing their snow and ice operations, training may be the key. Representatives from Milwaukee will share their experiences in working to fully staff their snowplow team. This session suggests that training existing labor and managerial staff could help municipalities complement their snow-fighting efforts.

Automatic Spreading—Science Fiction or Modern Technology?
The concept of automatic spreading may sound implausible to some, but the technology has been implemented successfully in Europe, and one North American agency harnessed it during the winter of 2005–2006. The system determines how much salt to spread, enabling the driver to focus on plowing.
