What happens to the tank after the propane stops

Establish these two facts before anything else

1. Do you own the tank, or is it leased? If it is leased, it is the supplier's property and only they may remove it. You cannot hire a third party to take it, and doing so creates a genuine liability. See the lease page.
2. Is it above ground or buried? An above-ground tank is a straightforward purge-and-lift. An underground tank opens a separate set of options and obligations.

The three legitimate end states

Supplier removal (leased tanks)

The supplier schedules a pump-out of remaining product, purges the vessel, disconnects it and hauls it away. Terms on remaining fuel, removal fees and notice periods are set by your lease.

Full extraction (owned tanks)

Vessel is emptied, purged of vapour to a safe concentration, disconnected, excavated if buried, and removed. The cleanest outcome and the one that leaves no future disclosure obligation.

Abandonment in place (buried tanks only)

Where excavation would damage a septic field, a retaining wall, a driveway or mature landscaping, a buried tank may be permanently decommissioned in place: emptied, purged and rendered inert, fittings removed or permanently sealed, and the vessel filled with an inert material such as sand or flowable fill so it cannot collapse or migrate.

The fourth option — disconnecting the line and leaving a charged or unpurged tank in the ground — is not an end state. It is a deferred problem that will surface at your next property sale, and it is the condition we most often find on mountain properties that changed hands two or three owners ago.

Purging is the safety-critical step

An 'empty' propane tank is not empty. It contains propane vapour, and a vessel containing vapour and air within the flammable range is far more dangerous than a full one. Every legitimate decommissioning sequence handles this the same way:

1. Remaining liquid is pumped out or burned off to the lowest practical level.
2. The vessel is vapour-purged, commonly with an inert gas, until the internal atmosphere is verifiably outside the flammable range.
3. Purge completion is confirmed by measurement, not assumption.
4. Only then are fittings removed, or the vessel cut, lifted or filled.

This work falls under NFPA 58, the Liquefied Petroleum Gas Code, which Georgia adopts, and it is performed by personnel qualified and equipped for it. Anyone offering to cut into or excavate a tank that has not been verifiably purged should be removed from your property.

Local requirements and the paperwork that matters later

Requirements vary by jurisdiction and change. Before work begins, confirm directly with Pickens County and, if you are inside a municipality, the city:

• Whether a permit is required for removal or for abandonment in place.
• Whether abandonment in place is permitted at all for your tank size and location, and what fill material is acceptable.
• Whether inspection or sign-off is required before backfill.
• What documentation is issued on completion.

Keep the completion documentation permanently. At resale, a buyer's inspector who finds evidence of a buried tank will ask what happened to it, and 'the previous owner said it was fine' is not an answer that closes a transaction. In a gated community there may also be an architectural or environmental committee with its own requirements — see the Big Canoe page.

Sequence it in this order

1. New heating system installed, commissioned and verified working through at least one genuinely cold night.
2. Gas piping capped and pressure-tested. See gas line capping.
3. Supplier notified, lease terminated, final pump-out scheduled.
4. Tank purged, then removed or abandoned to code.
5. Site restored, documentation filed with your property records.
