FAQ
Why does a gas station Phase 1 ESA cost more than office retail?
Petroleum retail sites carry higher inherent REC risk. Consultants spend more time on UST agency files, historical tank registration, and adjacent auto uses than on a typical strip retail tenant.
Does a decommissioned UST always trigger Phase 2?
Not always. If closure documentation and regulatory sign-off are complete and consistent with field observations, many deals proceed without Phase 2. Missing or ambiguous closure records are what usually drive further testing.
