Frac Sand Transloading Terminal to Move 550,000 TPY


Canadian National (CN) announced it will start serving a new state-of-the art frac sand terminal north of Grande Prairie, Alberta, Canada, starting in November 2013.

The new 20-acre facility being built by Di-Corp of Edmonton will have an annual throughput capacity of 550,000 tons of frac sand and have three tracks capable of holding 44 rail cars for unloading.

Trevor Derksen, vice-president of marketing at Di-Corp, a distributor of specialty chemicals, parts and accessories serving mining and drilling industries in Canada and the United States, said: “We are very pleased to be working with CN on this project in northwestern Alberta to help accommodate existing and expected growth in frac sand demand in the Western Canadian Sedimentary Basin. CN is an outstanding partner, providing cost-effective and reliable logistics services from frac sand origin in the Wisconsin Basin to destinations in Western Canada.”

“Di-Corp is an important customer of ours, and we expect to help the company move more frac sand to energy markets, said Doug MacDonald, CN vice-president, industrial products. “The new transloading terminal will create additional offloading and storage capacity at destination and also give our origin frac sand producers in the U.S. Midwest, Manitoba and elsewhere greater supply chain efficiencies and new market opportunities.”

CN is investing significantly in its frac sand franchise. CN announced last month it was accelerating work on the $33 million-upgrading of a 74-mile rail line between Wisconsin Rapids and Blair, Wis., to increase car-loading capacity and train velocity for growing frac sand supply chains. In 2012, CN spent $35 million to restore a 40-mile rail line between Ladysmith and Poskin, Wis., to serve the frac sand market.

“Customers are at the forefront of CN’s business agenda. Through Operational and Service Excellence and continuing innovation, CN is focused on creating value for its customers and transforming the railway into a true supply chain enabler,” said MacDonald.
