                       TRANSPORTATION (CONTINUED)
 
PART 195--TRANSPORTATION OF HAZARDOUS LIQUIDS BY PIPELINE--Table of Contents
 
                     Subpart C--Design Requirements
 
Sec. 195.132  Design and construction of aboveground breakout tanks.

    (a) Each aboveground 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.
    (b) For aboveground breakout tanks first placed in service after 
October 2, 2000, compliance with paragraph (a) of this section requires 
one of the following:
    (1) Shop-fabricated, vertical, cylindrical, closed top, welded steel 
tanks with nominal capacities of 90 to 750 barrels (14.3 to 119.2 m \3\) 
and with internal vapor space pressures that are approximately 
atmospheric must be designed and constructed in accordance with API 
Specification 12F.
    (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 Standard 620.
    (3) Vertical, cylindrical, welded steel tanks with internal 
pressures at the tank top approximating 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 Standard 650.
    (4) High pressure steel tanks (i.e., internal gas or vapor space 
pressures

[[Page 143]]

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 Standard 2510.
