Subpart 151.05—Summary of Minimum Requirements for Specific Cargoes
§151.05-1 Explanation of column headings in Table 151.05.
§151.05-2 Compliance with requirements for tank barges carrying benzene and benzene containing cargoes, or butyl acrylate cargoes.
Table 151.05 to Subpart 151.05 of Part 151—Summary of Minimum Requirements
(a) Cargo identification/name. This column identifies cargoes by name. Words in italics are not part of the cargo name but may be used in addition to the cargo name. When one entry references another entry by use of the word “see” and both names are in roman type, either name may be used as the cargo name (e.g., “Diethyl either see Ethyl ether”). However, the referenced entry is preferred.
(b) Cargo identification/pressure. This column identifies cargo in terms of pressure within the tank. Terms used are:
(1) Pressurized. Cargo carried at a pressure in excess of 10 pounds per square inch gauge as measured at the top of the tank (i.e., exclusive of static head).
(2) Atmospheric pressure. Cargo carried at not more than 10 pounds per square inch gauge, exclusive of static head.
(c) Cargo identification/temperature. This column identifies the cargo by the temperature of the cargo during transit.
(1) Ambient temperature. Cargo which is carried at naturally occurring temperatures.
(2) Low temperature. Cargo carried below ambient temperatures when the product temperature is below 0 °F.
(3) Elevated temperature. Cargo carried above ambient temperatures.
(d) Hull type. This column refers to the flotation features of the barge. Terms used are explained and defined in Subpart 151.10 of this part.
(e) Cargo segregation/tanks. This column refers to the separation of the cargo from its surroundings. Terms are explained in §151.13-5 and in footnotes to Table 151.05 of this part.
(f) Tanks/type. This column refers to the design requirements for cargo tanks and their placement within the hull of the vessel. Terms are explained in §151.15-1.
(g) Tanks/venting. This column refers to arrangements for preventing excess pressure or vacuum within the cargo tank. Terms used are explained and defined in §151.15-5.
(h) Tanks/gauging devices. This column refers to arrangements provided for determining the amount of cargo present in cargo tanks. Terms used are explained and defined in §151.15-10.
(i) Cargo transfer/piping. This column refers to the classification of piping in accordance with Subchapter F of this chapter as discussed in §151.20-1.
(j) Cargo transfer/control. This column refers to the valving requirements for the cargo piping system. These requirements are defined in §151.20-5.
(k) Environmental control/cargo tanks. This column refers to control of the composition of the environment within cargo tanks. Definitions and detailed requirements are given in §151.25-1.
(l) Environmental control/cargo handling space. This column refers to control of the environment in the cargo handling spaces. Definitions and detailed requirements are found in §151.25-2.
(m) Fire protection. This column specifies whether portable fire extinguishers are required on barges carrying the cargo named. Requirements for cargoes requiring extinguishers are given in Subpart 151.30 of this part.
(n) Special requirements. This column refers to requirements in subparts 151.40, 151.50, 151.55, 151.56, and 151.58 of this part which apply to specific cargoes. The section numbers listed omit the preceding part designation, “151”.
(o) Electrical hazard class—group. This column lists the electrical hazard class and group used for the cargo when determining requirements for electrical equipment under subchapter J (Electrical engineering) of this chapter.
(p) Temperature control installations. This column refers to systems which are used to control the temperature of the cargo. Definitions and requirements which are applicable if such systems are used are given in Subpart 151.40 of this part.
(q) Tank inspection period. This column refers to the maximum period in years between internal cargo tank inspections. Applicable requirements are given in §151.04-5.

A tank barge certificated to carry benzene and benzene containing cargoes or butyl acrylate cargoes must comply with the gauging requirement of Table 151.05 of this part by August 15, 1998. Until that date, a tank barge certificated to carry benzene and benzene containing cargoes must meet either the gauging requirement of Table 151.05 or the restricted or closed gauging requirements in effect on September 29, 1994; and a tank barge certificated to carry butyl acrylate cargoes must meet either the gauging requirements of Table 151.05 or comply with the open, restricted, or closed gauging requirements in effect on September 29, 1994.

See Table 2 of Part 153 for additional cargoes permitted to be carried by tankbarge.
Terms and symbols:
Segregation—Tank—
Line 1—Segregation of cargo from surrounding waters:
i = Skin of vessel (single skin) only required. Cargo tank wall can be vessel's hull.
i i = Double skin required. Cargo tank wall cannot be vessel's hull.
Line 2—Segregation of cargo space from machinery spaces and other spaces which have or could have a source of ignition:
i = Single bulkhead only required. Tank wall can be sole separating medium.
i i = Double bulkhead required. Cofferdam, empty tank, pumproom, tank with Grade E Liquid (if compatible with cargo) is satisfactory.
Internal tank inspection—
G—Indicates cargo is subject to general provisions of 151.04-5(b).
Specific numbers in this column are changes from the general provisions.
Tank type: Ind = Independent.
PV = Pressure vacuum valve.
SR = Safety relief.
Gauging device: Restr. = Restricted.
1. The provisions contained in 46 CFR Part 197, subpart C, apply to liquid cargoes containing 0.5% or more benzene by volume.
