Notwithstanding any provision to the contrary found in this chapter or found in the International Fire Code or NFPA 30A as adopted by reference herein, aboveground petroleum storage tanks may be used to store flammable and combustible liquids in motor fuel dispensing operations, provided that all of the following apply: a. The facility is in an area covered by a disaster emergency proclamation issued by the governor pursuant to Iowa Code section 29C.6 or, if not in such an area, the facility has applied to the fire marshal and has been approved for storage of flammable and combustible liquids in compliance with this subrule. b. The facility has suffered damage which has rendered the storage tanks normally used by the facility for flammable and combustible liquids inoperable. Storage of flammable and combustible liquids in compliance with this subrule shall continue only for as long as the normal storage tanks are inoperable and in no event for more than 90 days.Exception: In extraordinary circumstances, storage of flammable and combustible liquids in compliance with this subrule may continue for more than 90 days if the facility has sought and received specific written approval from the fire marshal for such storage. c. The facility has written confirmation from the facility’s insurance provider that insurance coverage will apply while storage of flammable and combustible liquids in compliance with this subrule is occurring. d. Any aboveground petroleum storage tank used pursuant to this subrule shall be rated or listed by an independent testing laboratory for aboveground storage of flammable and combustible liquids. e. Any aboveground petroleum storage tank used pursuant to this subrule shall be of no more than 1,000 gallons capacity.Exeption: A storage tank larger than 1,000 gallons capacity may be used pursuant to this subrule if the facility has received specific written approval from the fire marshal for its use. In reviewing such a request, the fire marshal shall consider, but is not limited to considering, the following factors: (1) Volume of throughput of the facility. (2) Ability to meet setback requirements appropriate to the size of the tanks used. f. All electrical service proximate to the storage area shall comply with applicable provisions of NFPA 70, National Electrical Code, 2005 edition.

Precautions shall be taken to prevent the ignition of flammable or combustible liquids, including the conspicuous posting of warning signs saying “NO SMOKING” and “NO OPEN FLAME.” i. Aboveground petroleum storage tanks used pursuant to this subrule shall be plumbed into existing dispensers, if practical. If this is impractical, all fueling at the facility shall be by attendant only; no self-service dispensing shall be allowed at the facility. j. Any aboveground petroleum storage tank used in compliance with this subrule shall be located so as to be protected from prospective damage from vehicle collisions and shall be located with due regard to vehicular traffic patterns and the location of property lines and significant buildings, particularly those which are frequently occupied by humans.Related ARC(s): 7977B, 8114B, 9283B, 9620B661221.5(101) Aircraft fueling.
