Minneapolis-St Paul Area Metals Factory Phase 1 Environmental Assessment

Caltha LLP Project Summary

Project: Phase 1 Environmental Site Assessment 
Client: Developer 
Location(s): Saint Paul, Minnesota
Key Elements: ASTM Phase 1 Environmental Site Assessment, Tier I Vapor Encroachment Screening Assessment, ASTM E2600-10
Caltha conducted an Phase 1 Environmental Site Assessment meeting the requirements of E 1527:15 and "All Appropriate Inquiry". The site was the location for a historical metal products factory dating at least since 1925 and was later converted to a plastics factory. The assessment included reviews of historical maps which documented site development over a 90 year period and the locations of key industrial equipment and processes, and storage locations for fuels. The on-site inspection identified other Recognized Environmental Conditions (REC) related to waste disposal systems and underground hydraulic systems. Current and historic issues were also identified as potential soil vapor intrusion risks.
