Wyoming Lime Producers

Wyoming Lime Producers (WLP), a division of Dakota Coal Company, owns and operates the Frannie Lime Plant, a limestone processing plant near Frannie, WY. 

The Frannie Lime Plant, Frannie, WY

The plant's lime kiln converts limestone to high-quality (high-calcium) lime through a high-heat calcining process. The cooled lime is then crushed to meet customer requirements and loaded onto railcars or trucks for delivery to Basin Electric's coal-based energy facilities for use in stack emission scrubbers and water treatment facilities. It also has other industrial uses.

Since its inception in 1993, Wyoming Lime Producers has purchased limestone from a nearby quarry managed by Montana Limestone Company. In 2002, Dakota Coal purchased Montana Limestone Company to have better control over the quality of limestone mined.Lime quality has a direct relationship with limestone quality. All coal-based power plants that use a dry scrubber system are demanding higher quality lime because of the more stringent Clean Air Act requirements.

Customers include power plants operated by Basin Electric, PPL Montana and Otter Tail Power Company.
