(A) Container location. Containers shall be located with respect to buildings, public ways and lines of adjoining property which can be built on in accordance with the following table:

x 3.785 for L | x 304.8 for mm | ||
Less than 125 (note 3, 4) | 10 | 5 (note 5) | None |

90,001 to 120,000 | 50 | 125 | |
NOTES TO TABLE: | |||
Note 1. Minimum distance for underground containers shall be measured from the pressure-relief device and the filling or liquid-level gauge vent connection at the container; except that, all parts of an underground container shall be 10 feet (3,048 mm) or more from a building or line of adjoining property which can be built upon. | |||
Note 2. In applying the distance between buildings and ASME containers of a 125-gallon (473.2 L) or more water capacity, a minimum of 50% of this horizontal distance shall also apply to all portions of the building which project more than 5 feet (1,524 mm) from the building wall and which are higher than the relief valve discharge outlet. This horizontal distance shall be measured from a point determined by projecting the outside edge of such overhanging structure vertically downward to grade or other level upon which the container is installed. Distances to the building wall shall not be less than those prescribed herein. Exception: installations in which the overhanging structure is 50 feet (15,240 mm) or more above the relief-valve discharge outlet. | |||
Note 3. When underground multi-container installations are comprised of individual containers having a water capacity of 125 gallons (473.2 L) or more, such containers shall be installed so as to provide access at their ends or sides to facilitate working with cranes or hoists. | |||
Note 4. At a consumer site, if the aggregate water capacity of a multi-container installation, comprised of individual containers having a water capacity of less than 125 gallons (473.2 L), is 500 gallons (1,892.7 L) or more, the minimum distance shall comply with the appropriate portion of this table, applying the aggregate capacity rather than the capacity per container. If more than one such installation is made, each installation shall be separated from other installations by at least 25 feet (7,620 mm). Minimum distances between containers need not be applied. | |||
Note 5. The following shall apply to aboveground containers installed alongside buildings: 1. Containers of less than a 125-gallon (473.2 L) water capacity are allowed next to the building they serve when in compliance with Items 2, 3 and 4 below. 2. Department of Transportation specification containers shall be located and installed so that the discharge from the container pressure-relief device is at least 3 feet (914 mm) horizontally from building openings below the level of such discharge and shall not be beneath buildings unless the space is well ventilated to the outside and is not enclosed for more than 50% of its perimeter. The discharge from container pressure-relief devices shall be located not less than 5 feet (1,524 mm) from exterior sources of ignition, openings into direct-vent (sealed combustion system) appliances or mechanical ventilation air intakes. | |||
3. ASME containers of less than a 125-gallon (473.2 L) water capacity shall be located and installed such that the discharge from pressure-relief devices shall not terminate in or beneath buildings and shall be located at least 5 feet (1,524 mm) horizontally from building openings below the level of such discharge and not less than 5 feet (1,524 mm) from exterior sources of ignition, openings into direct-vent (sealed combustion system) appliances or mechanical ventilation air intakes. 4. The filling connection and the vent from liquid level gauges on either DOT or ASME containers filled at the point of installation shall not be less than 10 feet (3,048 mm) from exterior sources of ignition, openings into direct-vent (sealed combustion system) appliances or mechanical ventilation air intakes. | |||
Note 6. This distance is allowed to be reduced to not less than 10 feet (3,048 mm) for a single container of 1,200-gallon (4,542 L) water capacity or less; provided, such container is at least 25 feet (7,620 mm) from other LP-gas containers of more than 125-gallon (473.2 L) water capacity. | |||

(B) Maximum capacity. Within residentially zoned areas and the Community Business District, the aggregate capacity of any one-installation storage of LP-gas shall not exceed a 2,000-gallon water capacity.
