Do I need a Phase I ESA for a solar farm site?

Most lenders and investors require a Phase I ESA for solar farm financing. Even on greenfield agricultural land, historical use (pesticide storage, fuel tanks, fill) can create environmental liability. A Phase I ESA is standard due diligence for any energy project site.
