Summary
O'Fallon caps the aggregate water capacity of any single liquefied petroleum gas installation at 2,000 gallons within the areas the code restricts for congested or populated zones, unless the City Council approves a larger installation by ordinance. Industrial-zoned property is exempt, and the Fire Code Official can adjust the limit case by case.
6104.2 Maximum capacity within established limits. Within the limits established by law restricting the storage of liquefied petroleum gas for the protection of heavily populated or congested areas, the aggregate capacity of any one installation shall not exceed a water capacity of 2,000 gallons (7,570 L) within the City limits of the City of O'Fallon, Missouri, unless specifically approved by ordinance. Exception 1: Storage is allowed in industrial zoned properties. Exception 2: In particular installations, this capacity limit shall be determined by the Fire Code Official, after construction of special features such as topographical conditions, nature of occupancy, and proximity to buildings, capacity of proposed LP-gas container, degree of fire protection to be provided and capabilities of the local Fire Department.

Full Breakdown
080: within the areas the code restricts for heavily populated or congested zones, the aggregate water capacity of any one LP-gas installation cannot exceed 2,000 gallons unless the City specifically approves a larger installation by ordinance. Two exceptions apply. First, storage is allowed without the cap on industrial-zoned property. Second, the Fire Code Official can adjust the 2,000-gallon limit for a particular installation after weighing site-specific factors: topography, the nature of the occupancy, how close the tanks sit to buildings, the container's rated capacity, the degree of fire protection already provided, and the local Fire Department's response capability. 2, both subject to the same industrial-zone exception and City Council approval route. 1 of Article III.
Violations & Fines
Exceeding the 2,000-gallon aggregate LP-gas cap without City Council approval, or violating any other Fire Code storage limit, is punishable under Section 112.4 by a fine of up to $500, imprisonment of up to 90 days, or both, with each day the violation continues charged as a separate offense.
