Summary
Propane (LP-gas) storage is regulated statewide by Wisconsin SPS 340, which adopts NFPA 58 for container design, siting and clearances. Only the container's owner or an authorized person may fill or refill it. Local zoning and fire codes may add setbacks.
No person other than the owner of a liquefied petroleum gas container or a person authorized by the owner may fill, refill, evacuate, or use in any other manner the container for any purpose.
Full Breakdown
Wisconsin does not leave propane storage to the county; LP-gas systems must be designed, installed, operated and maintained under Wis. Admin. Code SPS 340, which incorporates NFPA 58 and ANSI Z223.1/NFPA 54. Plans for larger tanks must show supports, foundations, clearances, relief valves and capacities. Reinstalled relief valves must be re-certified to ANSI/UL 132. Notably, no person other than the container's owner (or someone authorized by the owner) may fill, refill, evacuate or otherwise use the container. Local zoning and fire ordinances may impose additional distance requirements, so check with your municipality and fire department before siting a tank.
Violations & Fines
Installing or operating an LP-gas system contrary to SPS 340 can trigger state safety-and-buildings enforcement and require correction before use.
