(A) All storage systems which are to be constructed or installed after the effective date of this subchapter shall comply with the following construction, installation and testing specifications in addition to any requirements of state and federal law.
(1) All underground liquid storage systems of more than 1,000-gallon capacity shall be of vaulted construction, equipped with a failure detection system and protected both internally and externally from corrosion and structural failure. Non-corrosive tanks and transmission pipes listed by Underwriters’ Laboratories may be used in lieu of vaulted construction.
(2) Installation must be done strictly in accordance with manufacturer’s specifications and in accordance with installation procedures approved by the Building Official and/or Fire Marshal. Construction may proceed from stage to stage only upon approval by the inspecting official.
(3) The entire system shall be tested before it is covered as required by the Building Official and/or Fire Marshal. If a failure is detected, work may not proceed until the failure is repaired and the system is retested and no additional failures are found.
(B) (1) Above ground liquid storage systems above 1,000-gallon capacity must be placed within drainage collection areas sized and designed to capture and hold the entire contents of the largest tank of the storage system and to facilitate the recovery of any spillage, in the event of failure. Such drainage areas shall be constructed of impermeable material.
(2) Above ground storage of solid material which can produce a hazardous liquid when it comes into contact with water, must also be stored within a drainage area designed to collect the rain run-off and to recover the dissolved material. Such material may be permanently roofed in lieu of a drainage collection system, but the material must still be stored on a solid surface impermeable to any liquid produced from the material.
(3) Above ground systems and above ground parts of underground systems must be reasonably protected from damage by motor vehicles, trucks and vandalism.
