Finding
A registered UST facility matches this location (RINDALS FORT LEWIS TRADING POST, 24 ft): 2 open / 1 closed tank(s). No open leak cleanup within 1,500 ft is on record.

Distances are from EPA's recorded facility coordinates to the geocoded address. Coordinate
precision varies by state — facilities within 246 ft (~75 m) are treated as at/adjacent to
the parcel; confirm against the addresses shown.

"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.

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.
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.

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.
