MPCA conducts environmental review of proposed 5.4 million gallon asphalt-storage facility in Inver Grove Heights

Contact: Ralph Pribble, 651-757-2657

The Minnesota Pollution Control Agency (MPCA) today released its environmental assessment worksheet (EAW) for a proposed 5.4 million gallon asphalt cement storage facility in southern Inver Grove Heights. Bituminous Roadways Inc. has proposed to build a facility to store bulk asphalt at its asphalt plant and sand and gravel mine.

The project would be built in two phases on the company’s 200-acre site at 11201 Rich Valley Road.  Phase 1 includes building two 1.8 million-gallon asphalt cement storage tanks, associated truck loading and unloading equipment, and a small addition to an existing building. Phase 2 would add another 1.8 million gallon storage tank.   The project encompasses 6.5 acres in the northeastern portion of the existing mine site.

Like other Bituminous Roadways plants in the Twin Cities area, the Inver Grove Heights facility supplies liquid asphalt and sand and gravel to construction projects around the region. Asphalt will be transported to the site in tanker trucks, and pumped into the storage tanks. The company anticipates filling the tanks once a year during the winter months when market conditions are favorable. Traffic from the mine site is seasonal, mainly during the construction season. The project will generate a minimal amount of additional truck traffic.

State agencies use the EAW process to help decide whether a project requires a more extensive Environmental Impact Statement. The EAW covers site location details, nearby resources and other elements, including watersheds, soil types, planned excavations, stormwater management, and traffic.

The worksheet for this project is available on the MPCA Environmental Review webpage or by calling Patrice Jensen at 651-757-2465. Written comments may be emailed to, or mailed to her at the Minnesota Pollution Control Agency, 520 Lafayette Road N., St. Paul, MN 55155-4194. Comments must be received by August 19, 2020.
