Pioneer Part of 16-Year Silver Bow Creek Remediation

April 2, 2015

After 16 years, major remediation of Silver Bow Creek (Montana) is almost complete. Part of that remediation is the Greenway project. Since 1997, Pioneer has been the lead engineering firm on the Silver Bow Creek Greenway project providing planning, surveying, investigation, design, and oversight. Pioneer also helped write successful grants to fund the ecological restoration actions, provide public access, and purchase lands for public use and enjoyment. Since 1999 Pioneer has provided remedial investigation, design, restoration planning, and oversight services to DEQ and has been solely responsible for the 16-mile stretch from Miles Crossing to Warm Springs Ponds. Our efforts expanded the floodplain, lengthened the stream, and provided public access to the area. Now as the cleanup enters its final years, everyone’s efforts have paid off with a clean, restored stream, public access to walkways, and a viable recreational area. More on the project here.

Pioneer Receives National ACEC Award for Exemplary Engineering

March 16, 2015

Pioneer Technical Services Inc. has received a national recognition award for exemplary engineering achievement in the American Council of Engineering Companies (ACEC) 49th annual 2015 Engineering Excellence Awards competition. Pioneer won the award  for work on  the McLaren Tailings Abandoned Mine Site Reclamation Project in Cooke City. The project restored this remote 10-acre site while also cleaning contamination from Soda Butte Creek, preserving a fishery and the natural resources of Yellowstone National Park. The project team–Montana Department of Environmental Quality (DEQ), Pioneer, and Knife River–had to address shallow groundwater, a water-saturated tailings impoundment area, short construction seasons, and limited space for construction work and excavated material.

Using innovative techniques, the team dewatered the tailings impoundment so that excavation could proceed safely. More than one billion pounds of tailings were excavated, stabilized and placed in the repository, while approximately 100 million gallons of contaminated groundwater were treated during the project. Details of the project are here.

The award will be presented during the black-tie EEA Gala Awards program and dinner on Tuesday, April 21, 2015 at the Washington Marriott Wardman Park in Washington D.C.
