Former oil heat
Gas or heat-pump installation papers do not establish what happened to an old heating-oil tank. Trace the conversion and tank-work files separately.
A new heating system does not establish what happened to the old oil tank. Trace tank work separately from conversion work.
Ask for the separate tank permit/report and identify which property areas remain uninvestigated. Conversion papers and an empty database search do not resolve physical presence.

Choose your situation and the document categories you have. Get research targets and the relevant official routes—not a safety or closing verdict.
No address, email or upload. Choices stay in this page's memory; they are not saved, added to the URL or sent by this checker. Copy is optional and puts the checklist on your clipboard.
Research targets are not universally required documents. No document is authenticated here. This checklist does not certify compliance, no contamination, tank absence or readiness to close.
Based on your selections—not a determination of missing legal requirements. Environmental papers apply only if a relevant case exists.
Request outline: “Please provide the existing [specific missing document] associated with [permit/case reference] at [property], during [dates]. I already hold [list]. Please identify the custodian or any retention/coverage limit.” Replace the placeholders privately; this checker does not collect them or send a request.
These are starting routes, not proof that a file exists. Use a local route only when its named jurisdiction matches the property; the office and historical jurisdiction still matter.
Confirm the legal jurisdiction and the office holding tank-work records. A state facility registry may exclude home heating-oil tanks. No tailored rule for your location is implied here.
EPA: heating-oil tank scope ↗Keep municipal permits/completion records separate from NJDEP remediation papers. NJDEP says an NFA is not needed for a UHOT closure with no evidence of discharge that passed municipal inspection. This checklist does not establish those conditions for your property.
NJDEP UHOT FAQs, questions 15, 17 and 30 ↗NYSDEC says most home heating-oil tanks below 1,100 gallons are outside state PBS regulation, with delegated-county differences. Check local work records separately from spill records. Nassau's small-tank verification route is not statewide.
NYSDEC homeowner guide ↗DEQ distinguishes emptying from decommissioning. Clean-decommissioning certificates and leaking-HOT projects use different record searches. Ask about older missing files; do not treat an emptying receipt as a decommissioning report.
Oregon DEQ buying/selling guidance ↗Tank-work records follow the actual city or county custodian. Seattle's residential dataset distinguishes permit issuance from reported decommissioning details and has historical limits; it is not a statewide lookup.
Seattle residential UST dataset ↗Before you search
Conversion date and installer; prior oil-system clues; alleged tank work date; tank permit/report reference; legal jurisdiction at the work date.
Bring what you have. Missing identifiers can be part of the route review.Record what the conversion invoice actually describes. Oregon's unused-tank guidance addresses the former underground tank separately from the new heating source. Look for an explicit tank-work reference rather than reading removal into furnace or heat-pump installation language.
Official sourceOregon DEQ buying/selling guidance↗Search the local office for tank-work permits and completion attachments. Seattle's residential dataset, for example, records permitted decommissioning and follow-up details, not every historic heating conversion. Its coverage limits do not apply to all other cities.
Official sourceSeattle residential tank-record scope↗A blank record search does not settle whether an unrecorded tank remains. Oregon recommends a qualified expert when tank presence is unknown. Keep documentary research and any owner-authorized physical investigation as separate tracks with their own scope and findings.

A new heating system does not establish what happened to the old oil tank. Trace tank work separately from conversion work.
Match the permit, tank location, work date and removal versus closure-in-place wording.
Still missing? Records the issuer's stated work outcome within its scope.
Check tank identity, method, photographs, disposal references and named attachments.
Still missing? Describes the reported tank work; an invoice alone may not contain the supporting report.
Look for a separate tank-work reference rather than assuming conversion includes removal.
Still missing? Document heating-system work, not necessarily what happened to the former tank.

Your private record worksheet
Prepare search keys here, open the official sources above, then record what happened. Nothing is searched or sent automatically. A postal city or ZIP does not establish legal jurisdiction.
Suggested document scope for this route: Final inspection / completion record, Contractor's tank-work report, Oil-to-gas / heat-pump conversion papers. Narrow this to the files you still need.
Start with the identifiers and first applicable source. An online blank, an inaccessible portal and an agency no-record reply are three different outcomes.
No result is not proof of no tank. A candidate document still needs its property, issuer, dates and stated scope checked.
Review and edit bracketed fields after copying. Use the agency’s current official form, disclosures and fee instructions. Drafted ≠ sent ≠ acknowledged ≠ delivered.
Default: this tab’s session only. Device saving is optional; avoid it on shared devices. No property details enter the page URL or analytics.
Optional human research is available for NJ/NY, subject to intake review. The worksheet is separate and is not attached automatically.
Make the request specific
Please provide existing oil tank removal/closure permits, inspections and completion attachments for [property], approximately [years]. Heating conversion occurred in [year], but I have not located a separate tank-work record. Known reference: [number].
Replace the bracketed fields and follow the agency’s current form, disclosure, and fee instructions. This is a draft, not a sent request.
Conversion, capped pipes and missing records are not tank-free findings. Do not enter, open or investigate a tank yourself through this workflow. Professional physical assessment may still be needed.
