Iowa Code Chapter 101 provides for the regulation

by the State Fire Marshal. The Flammable Liquids Section has the primary
responsibility for carrying out this charge.
The following responsibilities are assigned to the
Flammable Liquids Section:
-
Enforcement of requirements for the safe transportation, storage,
handling, and use of flammable and combustible liquids, set out
in 661
Iowa Administrative Code, Chapter 221
-
Enforcement of requirements for the safe transportation, storage,
handling, and use of liquefied petroleum gas (LP-gas or propane),
set out in 661

Administration of the Aboveground Petroleum Storage Tank Registration
Program, the rules for which are found in 661
Iowa Administrative Code, Chapter 224
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). Remember to include details concerning:
- the UL listing of the tanks,
- necessary distances from the tanks,
- specifications for normal venting,
- emergency venting,
- secondary containment,
- piping,
- fuel dispensers,
- electrical wiring,
- required valves,
- warning signs,
- the fire extinguisher, and
- any other details or information needed to show the
installation will meet the requirements when double wall tanks or vaults
are used.
- for refineries or bulk plants, complete layout of buildings, tanks,
loading and unloading docks and heating devices.
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 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.
Tanks that do not need to be registered include:
- aboveground tanks of 1,100 gallons or less capacity;
- tanks used for storing of heating oil for consumptive
use on the premises where stored;
- underground tanks defined by Code of Iowa Section
455B.471; or
- flow-through process tanks or tanks containing regulated
substances, other than motor vehicle fuel for transportation purposes,
used as part of a manufacturing process, system, or facility.
