Sec. 442.2  General definitions.

    (a) In addition to the general definitions and abbreviations at 40 
CFR part 401, the following definitions shall apply to this part:
    Chemical cargos mean, but are not limited to, the following: latex, 
rubber, plastics, plasticizers, resins, soaps, detergents, surfactants, 
agricultural chemicals and pesticides, hazardous waste, organic 
chemicals including: alcohols, aldehydes, formaldehydes, phenols, 
peroxides, organic salts, amines, amides, other nitrogen compounds, 
other aromatic compounds, aliphatic organic chemicals, glycols, 
glycerines, and organic polymers; refractory organic compounds 
including: ketones, nitriles, organo-metallic compounds containing 
chromium, cadmium, mercury, copper, zinc; and inorganic chemicals 
including: aluminum sulfate, ammonia, ammonium nitrate, ammonium 
sulfate, and bleach. Cargos which are not considered to be food grade or 
petroleum cargos are considered to be chemical cargos.
    Closed-top hopper means a completely enclosed storage vessel used to 
transport dry bulk cargos, either by truck, rail, or barge. Closed-top 
hoppers are not designed or constructed to carry liquid cargos and are 
typically used to transport grain, soybeans, soy meal, soda ash, lime, 
fertilizer, plastic pellets, flour, sugar, and similar commodities or 
cargos. The cargos transported come in direct contact with the hopper 
interior. Closed-top hoppers are also commonly referred to as dry bulk 
hoppers.
    Drums mean metal or plastic cylindrical containers with either an 
open-head or a tight-head (also known as bung-type top) used to hold 
liquid, solid, or gaseous commodities or cargos which are in direct 
contact with the container interior. Drums typically range in capacity 
from 30 to 55 gallons.
    Food grade cargos mean edible and non-edible food products. Specific 
examples of food grade cargos include, but are not limited to, the 
following: alcoholic beverages, animal by-products, animal fats, animal 
oils, caramel, caramel coloring, chocolate, corn syrup and other corn 
products, dairy products, dietary supplements, eggs, flavorings, food 
preservatives, food products that are not suitable for human 
consumption, fruit juices, honey, lard, molasses, non-alcoholic 
beverages, sweeteners, tallow, vegetable oils, and vinegar.
    Heel means any material remaining in a tank following unloading, 
delivery, or discharge of the transported cargo. Heels may also be 
referred to as container residue, residual materials or residuals.
    Intermediate bulk container (``IBC'' or ``Tote'') means a completely 
enclosed storage vessel used to hold liquid, solid, or gaseous 
commodities or cargos which are in direct contact with the container 
interior. IBCs may be loaded onto flat beds for either truck or rail 
transport, or onto ship decks for water transport. IBCs are portable 
containers with 450 liters (119 gallons) to 3000 liters (793 gallons) 
capacity. IBCs are also commonly referred to as totes or tote bins.
    Intermodal tank container means a completely enclosed storage vessel 
used to hold liquid, solid, or gaseous commodities or cargos which come 
in direct contact with the tank interior. Intermodal tank containers may 
be loaded onto flat beds for either truck or rail transport, or onto 
ship decks for water transport. Containers larger than 3000 liters 
capacity are considered intermodal tank containers. Containers smaller 
than 3000 liters capacity are considered IBCs.
    Ocean/sea tanker means a self or non-self-propelled vessel 
constructed or adapted to transport liquid, solid or gaseous commodities 
or cargos in bulk in cargo spaces (or tanks) through oceans and seas, 
where the commodity or cargo carried comes in direct contact with the 
tank interior. There are no maximum or minimum vessel or tank volumes.
    On-site means within the contiguous and non-contiguous established 
boundaries of a facility.
    Petroleum cargos mean products of the fractionation or straight 
distillation of crude oil, redistillation of unfinished petroleum 
derivatives, cracking, or other refining processes. For purposes of this 
rule, petroleum cargos also include products obtained from the refining 
or processing of natural gas and coal. For purposes of this rule, 
specific

[[Page 440]]

examples of petroleum products include but are not limited to: asphalt; 
benzene; coal tar; crude oil; cutting oil; ethyl benzene; diesel fuel; 
fuel additives; fuel oils; gasoline; greases; heavy, medium, and light 
oils; hydraulic fluids, jet fuel; kerosene; liquid petroleum gases (LPG) 
including butane and propane; lubrication oils; mineral spirits; 
naphtha; olefin, paraffin, and other waxes; tall oil; tar; toluene; 
xylene; and waste oil.
    Pollution Prevention Allowable Discharge for this subpart means the 
quantity of/concentrations of pollutants in wastewaters being discharged 
to publicly owned treatment works after a facility has demonstrated 
compliance with the Pollutant Management Plan provisions in 
Secs. 442.15(b), 442.16(b), 442.25(b), or 442.26(b) of this part.
    Prerinse/presteam means a rinse, typically with hot or cold water, 
performed at the beginning of the cleaning sequence to remove residual 
material from the tank interior.
    Presolve wash means the use of diesel, kerosene, gasoline, or any 
other type of fuel or solvent as a tank interior cleaning solution.
    Rail Tank Car means a completely enclosed storage vessel pulled by a 
locomotive that is used to transport liquid, solid, or gaseous 
commodities or cargos over railway access lines. A rail tank car storage 
vessel may have one or more storage compartments and the stored 
commodities or cargos come in direct contact with the tank interior. 
There are no maximum or minimum vessel or tank volumes.
    Tank barge means a non-self-propelled vessel constructed or adapted 
primarily to carry liquid, solid or gaseous commodities or cargos in 
bulk in cargo spaces (or tanks) through rivers and inland waterways, and 
may occasionally carry commodities or cargos through oceans and seas 
when in transit from one inland waterway to another. The commodities or 
cargos transported are in direct contact with the tank interior. There 
are no maximum or minimum vessel or tank volumes.
    Tank truck means a motor-driven vehicle with a completely enclosed 
storage vessel used to transport liquid, solid or gaseous materials over 
roads and highways. The storage vessel or tank may be detachable, as 
with tank trailers, or permanently attached. The commodities or cargos 
transported come in direct contact with the tank interior. A tank truck 
may have one or more storage compartments. There are no maximum or 
minimum vessel or tank volumes. Tank trucks are also commonly referred 
to as cargo tanks or tankers.
    Transportation equipment cleaning (TEC) process wastewater means all 
wastewaters associated with cleaning the interiors of tanks including: 
tank trucks; rail tank cars; intermodal tank containers; tank barges; 
and ocean/sea tankers used to transport commodities or cargos that come 
into direct contact with the interior of the tank or container. At those 
facilities that clean tank interiors, TEC process wastewater also 
includes wastewater generated from washing vehicle exteriors, equipment 
and floor washings, TEC-contaminated stormwater, wastewater prerinse 
cleaning solutions, chemical cleaning solutions, and final rinse 
solutions. TEC process wastewater is defined to include only wastewater 
generated from a regulated TEC subcategory. Therefore, TEC process 
wastewater does not include wastewater generated from cleaning hopper 
cars, or from food grade facilities discharging to a POTW. Wastewater 
generated from cleaning tank interiors for purposes of shipping products 
(i.e., cleaned for purposes other than maintenance and repair) is 
considered TEC process wastewater. Wastewater generated from cleaning 
tank interiors for the purposes of maintenance and repair on the tank is 
not considered TEC process wastewater. Facilities that clean tank 
interiors solely for the purposes of repair and maintenance are not 
regulated under this Part.

methods of analysis in Table IB at 40 CFR 136.3, are defined as follows:
