Section V-30189 - Design and Construction of Above Ground Breakout Tanks [49 CFR 195.132]

A. Each above ground breakout tank must be designed and constructed to withstand the internal pressure produced by the hazardous liquid to be stored therein and any anticipated external loads. [ 49 CFR 195.132(a)]

B. For aboveground breakout tanks first placed in service after October 2, 2000, compliance with Subsection A. of this Section requires one of the following. [ 49 CFR 195.132(b)]

1. Shop-fabricated, vertical, cylindrical, closed top, welded steel tanks with nominal capacities of 90 to 750 barrels (14.3 to 119.2 m³) and with internal vapor space pressures that are approximately atmospheric must be designed and constructed in accordance with API Spec 12F (incorporated by reference, see §30107). [ 49 CFR 195.132(b)(1)]

2. Welded, low-pressure [i.e., internal vapor space pressure not greater than 15 psig (103.4 kPa)], carbon steel tanks that have wall shapes that can be generated by a single vertical axis of revolution must be designed and constructed in accordance with API Std 620(incorporated by reference, see §30107). [ 49 CFR 195.132(b)(2)]

3. Vertical, cylindrical, welded steel tanks with internal pressures at the tank top approximately atmospheric pressures [i.e., internal vapor space pressures not greater than 2.5 psig (17.2 kPa), or not greater than the pressure developed by the weight of the tank roof] must be designed and constructed in accordance with API Std 650 (incorporated by reference, see §30107). [ 49 CFR 195.132(b)(3)]

4. High pressure steel tanks [i.e., internal gas or vapor space pressures greater than 15 psig (103.4 kPa)] with a nominal capacity of 2000 gallons (7571 liters) or more of liquefied petroleum gas (LPG) must be designed and constructed in accordance with API Std 2510(incorporated by reference, see §30107). [ 49 CFR 195.132(b)(4)]
