Canadian Pacific Railway Limited (CP) announced a multi-year agreement with Unimin Corporation of New Canaan, Connecticut, for the movement of frac sand from Unimin’s facility in Wisconsin.

Unimin Corporation is North America’s leading producer of industrial minerals. Its new facility in 2013 in Tunnel City, Wisconsin, will open in 2013, and will produce two million tons of frac sand annually for energy markets in North Dakota, Texas, Colorado and elsewhere.

Under the agreement, CP will become the exclusive rail service pro­vider at this facility for the movement of frac sand to Unimin Cor­poration’s destination markets.

“We have a long relationship with CP at many of our plants in North America and we are delighted to expand this long-standing partnership,” said Kevin F. Crawford, President and CEO at Unimin. “Rail is an effective way to move our products and CP is a reliable partner that will enable us to continue to deliver products to critical energy markets.”
