still leave open?
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.

Document categories to ask about
Based on your selections—not a determination of missing legal requirements. Environmental papers apply only if a relevant case exists.
Copies you selected still need these checks

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.
Location changes the paperwork.
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.
Other location / not sure
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 ↗New Jersey
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.

New York
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.

Oregon
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.

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.

What each document can—and cannot—answer
- Tank-work permit
- Records permission for the described work, not necessarily its completion. Match issuer, property, work type and permit number; request the actual final disposition.
- Final inspection / completion record
- Records the issuer's stated work outcome within its scope. Match the permit, tank location, work date and removal versus closure-in-place wording.
- Contractor's tank-work report
- Describes the reported tank work; an invoice alone may not contain the supporting report. Check tank identity, method, photographs, disposal references and named attachments.
- Sampling report and lab attachments
- Documents the samples described in that report, not a guarantee about all soil or future conditions. Ask a qualified environmental professional to review sampling locations, dates, methods and any missing laboratory pages.
- Environmental case papers, if applicable
- Address a particular spill or cleanup case; they are not issued for every tank removal. Match the case reference and the actual final correspondence, its conditions and referenced reports.
- Physical tank-search report
- Describes the survey performed and its limitations; it is not a historic removal certificate. Read inspected areas, method, access restrictions and unresolved findings with the survey provider.
- Oil-to-gas / heat-pump conversion papers
- Document heating-system work, not necessarily what happened to the former tank. Look for a separate tank-work reference rather than assuming conversion includes removal.
- Agency no-records reply
- Reports the outcome of that agency's search within its stated scope. Keep the agency, record categories, date range and any referral; it is not a tank-free finding.
Read the answer first
Common paperwork problems.
Missing paperworkOil tank removed but no certificate: find the missing records
A missing removal certificate is a document gap, not proof that removal did or did not occur. Identify the local work record and any separate environmental file.
How to check a seller's oil tank removal claim
Preserve the exact claim: removed, emptied and filled in place are different actions. Compare the claim with property-matched work and completion records.
Conflicting oil tank permits, invoices, and closure papers
First check whether the papers describe the same tank and the same stage of work. An issued permit, contractor invoice and environmental letter answer different questions.
Request missing oil tank records from the right agency
A receipt, referral, no-records reply and delivered document are different outcomes. The scope of the agency search matters as much as its status.
Oil tank records or a tank sweep: which question comes first?
Records investigate documented history; a physical survey investigates the area and conditions within its scope. Neither automatically replaces the other.
Buying a house with an oil tank filled with sand: records to check
Filled in place is not removed. The fill material alone does not establish the complete work, sampling or environmental history.
Converted to gas but no oil tank removal records: what to check
A new heating system does not establish what happened to the old oil tank. Trace tank work separately from conversion work.
Oil tank removal permit not closed: find the final inspection record
A permit issue date is not a completion date. A blank online final status may need an attachment search or clarification from the issuer.
Oil tank NFA letter vs removal certificate: which record is missing?
An environmental closure letter and a local tank-work record have different scopes. In NJ, an NFA is not needed for every clean UHOT closure that passed municipal inspection.
Oil tank soil test records: find sampling reports and lab attachments
A statement that testing occurred is not the sampling and laboratory file. Records can locate the evidence; interpreting adequacy needs a qualified environmental professional.
