Phase 1 and Phase 2 Environmental Assessments for Solar PV Projects: Requirements, Process, and Timeline
Environmental Phase I and Phase II assessments serve as gatekeepers for solar photovoltaic development, determining whether a site harbors contamination that could derail financing, trigger costly remediation, or expose developers to liability. A Phase I Environmental Site Assessment (ESA) is a non-invasive desktop and visual review required by most lenders and investors to identify potential environmental red flags through historical records, regulatory databases, and site inspections.
