Pinnacle Engineering was hired by the owner of a five-acre property that was planned for redevelopment.  The property had formerly housed a feed plant complex and contained various grain bins, food oil storage tanks, processing/warehousing areas, and office areas. 

The client initially hired Pinnacle to perform a Phase I Environmental Site Assessment (ESA) and Investigation, which revealed the existence of soil impacted with arsenic and polynuclear aromatic hydrocarbons (PAHs).   Pinnacle prepared a Response Action Plan (RAP) and directed the excavation and removal of 5,000 cubic yards of impacted soil and the collection of confirmation samples, all in accordance with the RAP. 

Pinnacle prepared Brownfields redevelopment grant applications, and the client received more than $2.2 million in grants from the Metropolitan Council, Minnesota Department of Employment and Economic Development, and the City of Minneapolis.  The grant money was used for the cleanup of contaminated soil, pre-demolition activities (asbestos and lead paint management, hazardous materials removal and disposal), and building demolition, all of which was overseen by Pinnacle. 

The former occupant had declared bankruptcy and abandoned the facility several years earlier, leaving partially full grain bins and oil tanks.  Due to an economic downturn, the redevelopment project had been inactive for several years. During that time, the site was poorly secured and frequently vandalized, and when vandals destroyed piping in the facility that caused a release of vegetable oil from one of the tanks, Pinnacle provided emergency response services.   When redevelopment efforts resumed, the partially filled grain bins were discovered.  Disposing of this organic material was an expense that was not anticipated, and Pinnacle worked with another client that specializes in organic composting to arrange for the removal the organic materials (grain, vegetable oil, and fish oil) from the site at a minimal cost to Pinnacle’s client.

Pinnacle assisted in obtaining liability assurances for the developer and lenders, allowing the redevelopment project to proceed, and as a result of the remediation, the Minnesota Pollution Control Agency ultimately issued a “no further action” determination for the site.
