20. 21. 22. 23. 24. 25. Pi ing (cross-sectional diagram, including connections to tank and dispensers). P (A) Vent and tank riser primary containment system equipped with overfill prevention system that: _ Restricts delivery of flow to tank [Section 2635 (b) (2) (B) or (C)], or _ Provide positive shut off of flow to the tank at no more than 95 % [Section 2635 (b)(2)(C)l, or (B) Vapor recovery piping designed so it cannot contain liquid phase product, or (C) Suction piping (below grade piping operates at less than atmospheric pressure) [Section 2636 (a) (3)] _ Sloped so contents of the pipe will drain back into the storage tank if the suction is released. _ No valves or pumps installed below grade. Inspection method provided to demonstrate compliance with section 2636 (a) (3). (D) Corrodible underground piping protected against corrosion (Section 2636 (b)). (E) Underground primary piping will meet all of the following requirements Primary piping in contact with hazardous substance under normal operation conditions shall be: installed inside a secondary containment system in the form of:secondary pipe Vault or _lined trench to be sloped to a collection sump at the low point of the piping. Primary piping and secondary containment systems will be installed in accordance with industry code of practice and voluntary consensus standards.. Lined trench used as secondary containment Material compatible with the substance stored. Covered and capable of supporting any expected vehicular traffic. (F) Underground piping with secondary containment will be equipped and monitored as follows: Secondary containment will be equipped with a continuous monitoring system connected to an audible and visual alarm system. _ Automatic line leak detectors will be installed on pressurized piping Manufacturer: Model: _ Annual monitoring will be conducted on the pressurized piping with secondary containment. Annual line tightness test will not be required if the continuous monitor shuts down the pump and activates the alarm system when a release is detected and when the continuous monitoring system fails or is disconnected. _ State Water Resources Control Board "Facility (A)" and "Tank Permit (B)" application forms submitted.
