Industrial Facilities Phase I & Phase II

Industrial Facilities Phase I & Phase II

Industrial sites can present numerous environmental concerns that sometimes remain undiscovered until it is time to renovate or sell a property. When an environmental assessment associated with a transfer of property reveals hazardous substance contamination, owners must act quickly to keep the deal on track while ensuring compliance with local and state regulations. 

With deep regulatory knowledge and longstanding partnerships with government agencies, Pinnacle Engineering helps clients successfully navigate situations involving environmental contamination and remediation.  

Environmental Challenge

A client hired Pinnacle Engineering to conduct a Phase I Environmental Site Assessment (ESA) at their facility before transferring the property. During the assessment, engineers discovered that the facility previously operated as a foundry. Foundry sand was present on the property, and a vapor degreaser had been removed from the site many years earlier. 

These discoveries triggered the need for a Phase II ESA to determine the magnitude and extent of Trichloroethylene (TCE) contamination and a plan for excavating contaminated soils inside and outside the building. TCE can also contaminate groundwater, requiring additional assessments. Before any environmental remediation could begin, the team had to coordinate and seek approval of the activities with the Minnesota Pollution Control Agency (MPCA).

Technology & Engineering Solutions

Pinnacle Engineering worked closely with the MPCA Project Manager to expedite the review of the investigation work plan and data obtained during the Phase I and II assessments. Remediation work involved excavating soil inside the building where the vapor degreaser was previously located. 

To assess potential groundwater contamination, the team conducted a push probe investigation to collect samples at various depths throughout the site. Groundwater monitoring wells were installed in target areas to obtain groundwater data from shallow and deep horizons. An exterior trench investigation was also completed to determine whether a buried source of TCE existed.

Analysis & Results

Pinnacle Engineering demonstrated that the facility’s HVAC system provided sufficient air changes so that potential soil vapors entering the building posed a minimal risk to building occupants. We also provided evidence that no potential off-site receptors were at risk.

The team’s due diligence and partnership with the MCPA representative resulted in the timely issuance of liability assurances and a successful property transfer.

 

Our goal is to continue to build upon our reputation of delivering high-quality services, maintaining open and responsive communications, and providing cost-effective solutions that consistently meet our client’s needs.
