PART 461--BATTERY MANUFACTURING POINT SOURCE CATEGORY--Table of Contents
 
Sec. 461.2  General definitions.

    In addition to the definitions set forth in 40 CFR part 401, the 
following definitions apply to this part:
    (a) ``Battery'' means a modular electric power source where part or 
all of the fuel is contained within the unit and electric power is 
generated directly from a chemical reaction rather than indirectly 
through a heat cycle engine. In this regulation there is no 
differentiation between a single cell and a battery.
    (b) ``Battery manufacturing operations'' means all of the specific 
processes used to produce a battery including the manufacture of anodes 
and cathodes and associated ancillary operations. These manufacturing 
operations are excluded from regulation under any other point source 
category.
    (c) ``Ancillary operations'' means all of the operations specific to 
battery manufacturing and not included specifically within anode or 
cathode manufacture (ancillary operations are primarily associated with 
battery assembly and chemical production of anode or cathode active 
materials).
    (d) ``Plate soak'' shall mean the process operation of soaking or 
reacting lead subcategory battery plates, that are more than 2.5 mm 
(0.100 in) thick, in sulfuric acid.
    (e) ``Discharge allowance'' means the amount of pollutant (mg per kg 
of production unit) that a plant will be permitted to discharge. For 
this category the allowances are specific to battery manufacturing 
operations.
    (f) ``Miscellaneous wastewater streams'' shall mean the combined 
wastewater streams from the process operations listed below for each 
subcategory. If a plant has one of these streams then the plant receives 
the entire miscellaneous waste stream allowance.
    (1) Cadmium subcategory. Cell wash, electrolyte preparation, floor 
and equipment wash, and employee wash.
    (2) Lead subcategory. Floor wash, wet air pollution control, battery 
repair, laboratory, hand wash, and respirator wash.
    (3) Lithium subcategory. Floor and equipment wash, cell testing, and 
lithium scrap disposal.
    (4) Zinc subcategory. Cell wash, electrolyte preparation, employee 
wash, reject cell handling, floor and equipment wash.
    (g) ``Trucked batteries'' shall mean batteries moved into or out of 
the plant by truck when the truck is actually washed in the plant to 
remove residues left in the truck from the batteries.
