Ardmore Dauntless, a 38,000 deadweight-ton tanker, came up the North River Tuesday afternoon, arriving from Saint John’s, in New Brunswick, Canada. They went on to moor at the Innovative Surface Solutions plant located in Glenmont, south of Albany, which means magnesium chloride, the primary ingredient in the company’s deicing product, is a likely cargo. Innovative took over a former Texaco oil terminal at this site over ten years ago and converted it to a manufacturing facility, making it, along with the wallboard plant in Buchanan, the cement plant in Coeymans, and the soon-to-be-closed sugar refinery in Yonkers, one of the few remaining manufacturers to directly access the Hudson River marine highway via dedicated piers.
