Underground Storage Tanks and Property Due Diligence

A nearby tank or release record is a reason to ask better questions, not evidence that a property is contaminated. TrueViewly keeps inventory, release history and source limitations separate from its Environmental Risk score.

Practical guide

Property buyers, acquisition teams and insurance professionals preparing environmental follow-up.

Separate facilities, tanks and release records

EPA UST Finder organizes underground storage tank facilities and releases from dated public-source records. TrueViewly shows nearby geolocated facility and release counts separately, with source references and a capped nearest-record list.

  • The default radius is one mile. Distances are to source coordinates, not contamination boundaries or the property boundary.
  • Counts are source records, not necessarily unique incidents, affected properties or current operations.
  • Tank summaries require a unique state/facility match. Missing linkage remains unavailable, not zero.

Read cleanup status and coordinate quality together

Open, no-further-action and unknown are distinct source statuses. No further action does not prove all contamination is absent or establish whether a pathway affects this property.

  • Coordinates may be geocoded or approximate. Records without usable geometry are excluded from proximity counts.
  • Reported dates, substances, inspections and residual-contamination flags can be missing; an unknown flag is not a negative finding.
  • A new download or report does not refresh underlying state, territory or Tribal records. No nearby match does not establish a clean property.

Use source records for property-specific follow-up

Review current agency cleanup files and site history with an environmental professional. A proximity panel does not replace a Phase I environmental site assessment or another assessment appropriate to the transaction.

  • The Sonoma sample has two facility records and five release records within one mile; all five releases have a no-further-action source status.
  • Environmental remains 24 and the overall score remains 60. This new evidence does not change scores or weights.
  • The report does not determine contamination, liability, insurance eligibility, premiums or coverage.

Sources and further reading

Source publications and live agency pages may differ from the snapshot used in a report. Check the report's source dates and confirm material findings through the responsible authority.

Frequently asked questions

Does a nearby release mean property contamination?

No. It shows reported source history and proximity, not contamination, exposure or a pathway at the property.

Does no further action mean the property is clean?

No. It is an agency source status, not a property-wide finding that all contamination is absent.

Does UST evidence change the score?

No. It remains additional evidence, separate from existing Environmental and overall scoring.
