Sec. 180.603  Qualification of portable tanks.



    (a) Each portable tank used for the transportation of hazardous 

materials must be an authorized packaging.

    (b) To qualify as an authorized packaging, each portable tank must 

conform to the requirements of this subchapter and the applicable design 

specification to which the portable tank was constructed.

    (c) The following portable tanks are authorized for use provided 

they conform to all applicable safety requirements of this subchapter: 

51, 56, 57, 60, IM 101, IM 102 and UN portable tanks.

    (d) A portable tank that also meets the definition of ``container'' 

in 49 CFR 450.3(a)(3) must conform to the requirements in parts 450 

through 453 of this title for compliance with Annex II of the Convention 

for Safe Containers (CSC).

    (e) Exemption portable tanks based on DOT 51 portable tanks. The 

owner of a portable tank constructed in accordance with and used under 

an exemption issued prior to August 31, 1996, which was in conformance 

with the requirements for Specification DOT 51 portable tanks with the 

exception of the location of fill and discharge outlets, shall examine 

the portable tank and its design to determine if it meets the outlet 

requirements in effect on October 1, 1996. If the owner determines that 

the portable tank is in compliance with all requirements of the DOT 51 

specification, the exemption number stenciled on the portable tank shall 

be removed and the specification plate (or a plate placed adjacent to 

the specification plate) shall be durably marked ``DOT 51-E*****'' 

(where ***** is to be replaced by the exemption number). During the 

period the portable tank is in service, and for one year thereafter, the 

owner of the portable tank must retain on file, at its principal place 

of business, a copy of the last exemption in effect.
