Aboveground and Liquid Propane Storage Tank Plan Review Requirements

Before installing aboveground tanks storing flammable or combustible liquids, plans must be submitted to the Fire Marshal Division for approval in accordance with subrule 661 Iowa Administrative Code 221.3(3)

Engineering drawings of the storage facility are preferred but not required. Drawings must be to scale. Plans sealed by a licensed professional engineer are required if the facility is a refinery.

Local jurisdictions (full time fire departments) may require plans to be submitted to them for a local permit in addition to obtaining approval from this office. Consult your local jurisdictions for their requirements. Underground tanks which have been approved in accordance with the UST rule 591-15.6(455G) do not need to be submitted to the state fire marshal for approval. 

  • Aboveground Storage Tank Plan Review Fee: $100 + $25 per tank
  • Liquid Propane Tank Plan Review: No fees
Aboveground Storage Tank Registration Requirements

Aboveground petroleum storage tanks that are greater than 1,100 gallons in capacity must be registered with the state fire marshal's office. Note: Tank registration shall not be construed as plan approval. Plan approval is required for all tanks; registration is not.
