TD&H Engineering provided engineering services to Montana Specialty Mills for their move to a new industrial park property. Montana Specialty Mills refines oil seeds for various uses and ships their product throughout the country. The existing facility was in the center of the West Bank Brownfields site. This property, adjacent to the BNSF railroad right-of-way, was impacted by petroleum releases from the adjoining Cascade County Shop complex. TD&H Engineering performed ground water monitoring and analyzed soils for petroleum impacts and the potential for off-site sources of environmental impacts.
