Find the municipality, not just the mailing address
The office that governs a tank is the one on the deed. A tax bill, a closing packet, or the county parcel record will name that borough or township more reliably than the line above the ZIP code.
Levittown is a census place, not a fifth government. Houses there sit in Bristol Township, Falls Township, Middletown Township, or Tullytown Borough. A Yardley mailing address can be Yardley Borough or Lower Makefield Township. Doylestown can be the borough or the township. Middletown Township’s building office uses a Langhorne street address; that is not Langhorne Borough.
Removal, abandonment, and replacement
Middletown Township’s FAQ treats removal, abandonment, and new installation as permit work. Lower Makefield’s homeowner guide does the same for removal, replacement, and abandonment in place, and it asks for an inspection of the completed work.
Those two offices draw the lines in public. Other municipalities may use different paper. Closing a tank in place is not the same job as taking it out, and it is not the same job as replacing it so the house stays on oil.
Notification and inspection
Buckingham Township asks for Fire Marshal notice no later than 48 hours before start, and an inspector on site when a tank comes out of the ground. Northampton Township’s Fire Marshal application asks for notice no later than 24 hours before start and says inspections will be conducted during the removal. Lower Makefield inspects the completed work.
Those clocks belong to those offices. They do not travel. A general construction-inspection notice on another township’s permits page is not a tank-removal rule.
What a closed permit does not establish
A signed-off municipal permit shows the office closed its file. It does not decide whether soil under a buried tank is clean. That question, if it arises, belongs with underground removal and, when a sale is involved, with buying or selling.
