Phase 1 Environmental Site Assessments

Environmental due diligence affects acquisition risk, operational exposure, regulatory liability, and future development decisions. Guernsey completed 33 Phase 1 Environmental Site Assessments across Wisconsin for the PFM Group, supporting a broader Independent Engineers Report (IER) evaluating facility conditions, operational considerations, regulatory status, and health and safety performance.

Guernsey visited and evaluated all 33 sites as part of the assessment process. The work included development of an Environmental and Regulatory Summary documenting existing permits and approvals, operational limitations tied to those permits, and a general assessment of facility compliance conditions. A Health and Safety Overview was also prepared evaluating each facility’s reported health and safety performance relative to industry benchmarks, including a matrix of reported injuries and fatalities by individual facility.

The Phase 1 Environmental Site Assessments were performed in accordance with US EPA 40 CFR Part 312, “Innocent Landowners, Standards for Conducting All Appropriate Inquiries,” and ASTM 1527-13, “Standard Practice for Environmental Site Assessment: Phase I Environmental Site Assessment Process.”
