1. The following design standards apply to the construction of new aboveground storage tanks of 250 gallons or more of hazardous materials, excluding farm and municipal tanks holding motor fuel of 1,100 gallons or less and heating oil tanks used to heat homes or businesses:
A. The design and construction of aboveground storage tanks shall be in accordance with applicable Federal and State regulations.
B. Aboveground storage tanks shall be provided containment facilities which meet the following design requirements:
(1) The containment device shall be large enough to contain 110% of the volume of the tank, in cases where a single tank is used to store, handle, use or produce a hazardous material. In cases where multiple tanks are used, the containment device shall be large enough to contain 110% of the volume of the two largest tanks.
(2) All containment devices shall be constructed of materials of sufficient thickness, density, and composition to prevent structural weakening of the containment device as a result of contact with any hazardous material and shall be capable of containing any accidental release for at least a period sufficient to allow detection and removal of the material. Provisions shall be made for monitoring, testing, and immediate removal of accumulated precipitation.
C. The design of the tank shall meet applicable technical standards for the specific type and class of tank as set forth in the applicable underwriters Laboratory Standards No. 142 by the American Petroleum Institute (API), by the American Water Works Association (AWWA), or by the Society of Mechanical Engineers (ASNIE). The tanks shall be fabricated, tested, and installed in accordance with the appropriate codes and standards applicable to the material to be stored therein.
D. The tank shall be designed with monitoring standards consistent with the manufacturer's specifications.
E. The tank shall be tested as required by Federal and State codes and standards.
F. The tank and containment area shall be protected by a security fence.
G. The Operating Requirements described in § 26-242 shall be applicable for the operation of new aboveground storage tanks.
