"Open" = the state's cleanup case is not closed. "No Further Action" = the state closed the case to its standard at the time — residual contamination below that era's thresholds can remain.

EPA risk context

Computed by EPA for the facility at this parcel — context for the surroundings, not a property-line measurement.

  • 100-year floodplain: No
  • Private water wells within 1,500 ft: 25 — drinking-water wells are the main exposure path for tank leaks
  • Population within 1,500 ft: 446
  • Wellhead protection area: No · Source-water protection area: No
  • Land use at the facility: Developed, Open Space

How to read this screen

  • "Closed" ≠ clean. A closed tank was taken out of service per the registry. Many were closed in place or removed without soil testing, especially before the late 1990s. Closure is a paperwork status, not a certification that no contamination remains.
  • The ghost-tank caveat. Federal UST registration began in 1986 and exempts most residential heating-oil tanks. A property that pre-dates 1986 — or ever heated with oil — can have a tank no registry knows about. A clean screen cannot prove absence; only a physical tank sweep can.
  • Open leak nearby ≠ your problem (necessarily). Plume migration depends on soil, groundwater direction, and distance. An open cleanup within 500 ft deserves real attention; at 1,500 ft it is context.

Sensible next steps, with typical costs

  • tank sweep (GPR scan of the parcel) — typically $125–$400 [published incumbent rates: Oil Tank Sweep Premier — published pricing; Rush Locates — residential tank sweep FAQ; verified 2026-06-12]. The right answer to the ghost-tank caveat for a specific purchase.
  • Phase I Environmental Site Assessment (ASTM E1527-21) — typically $2,000–$4,500 (standard commercial parcel; gas stations and dry cleaners typically add 30–60%) [published incumbent rates: apprais.ai — Phase 1 ESA cost, 50-state guide; Phase1Finder — Phase 1 ESA cost guide; verified 2026-06-12]. What lenders require on commercial deals with tank history; this screen is preparation for one, not a substitute.

Methodology, sources & honest limits

  • EPA UST Finder — A national database of state-reported underground storage tank facilities, tanks, and leak (LUST) incidents, compiled and risk-annotated by EPA. States report different attribute sets — missing values are shown as not reported, never as zero. Source: https://www.epa.gov/ust/ust-finder · service: EPA ArcGIS FeatureServer · data vintage 2024-12-04.
  • Every facility and leak row links its registry record (the "Registry record" / "Record" columns) — the audit trail is the product.
  • Rings: at-parcel ≈ 75 m, then 500 ft / 1,500 ft. Distances use EPA's recorded coordinates; precision varies by state.
  • Missing values are shown as "not reported" — never as zero. States report different attribute sets.
This is a screen of EPA-registered tank and leak records, not an environmental site assessment. State registries are incomplete by design: tanks removed before 1986 and most residential heating-oil tanks were never registered, so a clean screen cannot prove the absence of a tank. "Closed" means a tank was taken out of service per the registry — it does not certify that no contamination remains.
