Purple salt?

Blizzards have closed the Denver airport and roads for a hundred miles and paralyzed the high plains economy, but I'll be heading home soon on dry roads for an evening's TV date as my beloved Green Bay Packers host the neighboring Minnesota Vikings this evening. (It's been a long season for faithful Packers fans, but that's another story).

Just up the road from us here in Northern Virginia, fans of the Baltimore Ravens are getting excited for the prospects of their team in the NFL's post-season (just a dream for the 2006 Packers, I'm afraid). Yesterday's Baltimore Sun carried the headline: "Ravens' success has city thinking salt and purple" It seems the city's salt this year is blue (from the use of Prussian Blue as an anti-caking agent, the paper didn't mention) and they're taking a look at trying to adjust the hue to honor the purple-and-black Ravens. The city has already changed the lighting on city buildings to purple. The paper explains that "winter in Baltimore may resemble a huge, grape-flavored snowball."

Keep praying for snow in Baltimore, even if purple's not your favorite team's color. And tonight I'm hoping there's no cause to consider a "purple" celebration after the game as my green-and-gold champions tough it out with an outfit that used to inspire "shock and awe" as the "Purple People Eaters" -- the Vikings.

CT switches from sand to salt to save environment

"DOT banishes sand from snowy highways" read the December 15 headline in the Connecticut Post Online. "Instead of seeing the brown ick of sand polluting the landscape," Connecticut drivers will soon see clear, black roads when it snows, explained journalist Rob Varnon. The CT DOT has replaced sand-salt mixes with straight salt -- the solution used in most states and the strong trend among professional snowfighters. Varnon continued:

Sand has traditionally been used to create traction on winter roads, but studies by the U.S. Department of Transportation and several universities during the last decade have called its effectiveness into question....The state DOT said it plans to use plows, salt and liquid calcium chloride to clear roads and also treat some surfaces before storms. ...Municipalities do not have to follow suit, but Connecticut requires towns and cities to clean up sand when it is placed on the roads because of the impact the material has on water supplies....The DEP discussed the DOT's winter plan, he said, and applauds the decision to quit using sand. Massachusetts, Vermont and New York have quit using sand because it is detrimental to the environment, he said.

Not only will switching to salt reduce the environmental burden, a DOT spokesperson said, but the public demands winter mobility only possible by using salt. "People are less and less patient. The DOT catches a lot of political heat if the roads aren't clear 24 hours after a storm," he explained.

Yes, we know. Good move, Connecticut!

Salt trucks = re-election

Successful politicians understand the relationship of "ends" and "means." For many elected officeholders, the "end" can be summed in one word: "re-election" -- after all, you can't do all those other good things if you're turned out of office. This season of the year, we're reminded that the "means" can be summed in two words: "salt trucks."

That's the conclusion of Halifax, Nova Scotia Chronicle-Herald columnist Marilla Stephenson anyway. Writing in the lee of a 19-centimeter snowstorm that devasted the city last Monday, she gave voice to what was likely a broad frustration:

I have had it up to you-know-where with the pathetic performance at city hall, often masked by attempts to blame people for their own misfortune. The best defence is a good offence, as the old strategy saying goes. Blame somebody else.

In all the blame-shifting spewing from the condescending mouths at city hall over the past few days, I never heard the words "salt truck" from any of them. Just excuses about 100-odd snowplows being caught in the same gridlock as the rest of us. Oh, and there was that city bus blocking the bridge. Tee-hee-hee.

All the problems they were droning on about happened after it was too late to do anything about the gridlock. What about before?

Don’t we have any SALT trucks?

And if we do, why were they not dispatched to salt major arterial routes, especially outbound from our traditionally traffic-challenged peninsula, as soon as the snow began?

Nope, it’s sit tight and let’s see what happens.

What passes for winter road maintenance in this municipality becomes more of a joke every year. They argue down at the big round table for hours about whether one councillor’s district gets plowed sooner than another’s in the 24 or 48 hours after a storm, and they take turns accusing staff of failing to answer questions.

Has anybody asked why, year after year, commuters are reduced to three-hour trips home — trips that normally take 20 to 30 minutes — when we are hit with something in the meagre vicinity of four inches of snow? This is nothing new. Monday’s snow came fast, but it doesn’t take nearly as much as the 19 centimetres that fell (only eight inches, by the way) to create havoc during rush hour.

This, from a city administration that keeps boasting about our world-class city, our smart city, our progressive city, is not performance.

Mayor Peter Kelly at least had the good sense to acknowledge the city "didn’t get it right." The master of understatement went on to say that a review had been launched. "If we can find a better way in which to do it, then we have that responsibility to do so," he told The Chronicle Herald.

Two words, Peter: SALT TRUCKS.

She continues:

I seem to recall a forecast issued as early as the preceding Friday warning about snow on Monday. So it’s early December and rain changes to snow a few hours early, and this comes as some kind of a tremulous shock to the folks in charge of winter maintenance? Still, there’s not a salt truck in sight.

By the time I got home, I was locked in a white-knuckle catatonic state somewhere between raging fury and bitter resignation. Three hours had elapsed since my trip began.

I saw one plow, going the other way with its blade up, in that whole time. Oh, and at one point there was a garbage truck collecting trash on Oxford Street. That sure helped move things along.

I’m sure every driver in every one of those cars has a similar story, as does every commuter who waited in vain for a bus that never arrived.

I accept that Mother Nature plays a part in winter traffic gridlock, but I am sick and tired of excuses that suggest we have no technology to fight back. ...

I can’t help but think that a little strategically placed salt when the storm first hit could have enabled a lot of drivers to get home sooner....

Good advice, Ms. Stephenson: salt trucks, indeed.

CaCl over-application produces slickness, crashes

Ten crashes in Ft. Wayne, IN have been blamed on an IN DOT anti-icing application of calcium chloride with a rust inhibitor which the agency confesses caused rather than prevented slickness. Four crashes caused injuries according to a sotry in the Ft. Wayne Journal Gazette.

Tragic, of course, but agencies are simply responding to public concerns that they find some "alternative" to using tried-and-true sodium chloride and such incidents are the inevitable result of experimentation with new materials and techniques. Let's be clear, however, anti-icing itself wasn't the problem here, nor was salt (sodium chloride) involved in any way.
