Caltha LLP Project Summary
Project: Phase 1 ESA For Historic Industrial Brownfield Property
Client: National Food Sector Corporation
Location(s): Minneapolis – Saint Paul Area, Minnesota
Key Elements: Phase 1 Site investigation, Tier I Vapor Encroachment Screening Assessment, ASTM E2600-10
Overview: Caltha LLP conducted a Phase 1 Environmental Site Assessment for this historical industrial property located in the suburban Minneapolis – Saint Paul Area. The property had been in industrial use since the late 1880s and had gone through several soil and groundwater cleanups to allow for redevelopment. The Phase 1 ESA looked at current operations on the property, but also reviewed documentation of past investigations and site remediation work completed by an earlier property owner.

The Phase 1 assessment also included a Tier I Vapor Encroachment Screening Assessment using ASTM E2600-10. The prospective purchaser intended to renovate existing building and to construct new buildings on the site. Findings determined that some cleanup projects completed by the earlier owner were not finalized and residual contamination remained on the property. The Tier I Vapor Encroachment Screening Assessment determined that on-site vapor sources should be further evaluated to determine if vapor mitigation should be incorporated into site development plans.

Environmental reviews for sites previously investigated and cleaned up need to consider the potential impact of any contamination left on the property on future uses of the site.
