Title 35 - ENVIRONMENTAL PROTECTION
Part 307 - SEWER DISCHARGE CRITERIA
Subpart CT - NONFERROUS METALS FORMING AND METAL POWDERS
Section 307.8100 - General Provisions
Universal Citation: 35 IL Admin Code ยง 307.8100
Current through Register Vol. 48, No. 52, December 27, 2024
a) Applicability
1) This Subpart CT applies to
the introduction of pollutants into a POTW from the forming of nonferrous
metals (including nonferrous metal alloys), except beryllium, copper, and
aluminum, and their alloys. Aluminum alloys are defined as any alloy in which
aluminum is the major constituent in percent by weight. Copper, alloys are
defined as any alloy in which copper is the major constituent in percent by
weight except when copper is alloyed with precious metals. Any copper-precious
metal alloy containing 30 percent or greater precious metal is considered a
precious metal alloy for this Subpart CT. Beryllium alloys are any alloy in
which beryllium is present at 0.1 percent or greater. This Subpart CT applies
to the following:
A) Forming operations,
including rolling (both hot and cold), extruding forging, drawing, swaging,
cladding, and tube reducing, and
B)
Ancillary operations performed as an integral part of the forming of these
metals, including casting for subsequent forming, heat treatment, surface
treatment, alkaline cleaning, solvent degreasing, product testing, surface
coating, sawing, grinding, tumbling, burnishing, and wet air pollution
control.
2) This Subpart
CT also applies to the introduction of pollutants into a POTW from mechanical
metal powder production operations, the forming of parts from metal powders,
and associated ancillary operations of the following:
A) Iron, copper, and aluminum and their
alloys; and
B) The nonferrous metal
and their alloys described in subsection (a)(1). This Subpart CT does not
regulate the production of metal powders by chemical means such as
precipitation. The production of metal powder as the final step in refining
metal is regulated under nonferrous metals manufacturing, Subpart V.
3) Surface treatment includes any
chemical or electrochemical treatment applied to the surface of the metal. For
this Subpart CT, surface treatment of metals is considered to be an integral
part of the forming of metals whenever it is performed at the same plant site
at which the metals are formed. These surface treatment operations are not
regulated under the electroplating or metal finishing rules in Subpart N or
AH.
4) Casting is covered by this
Subpart CT when it is performed as an integral part of the metal forming
process and takes place at the same plant site at which metals are formed. Such
casting is not regulated under the provisions of metal molding and casting
(Subpart CM).
5) This Subpart CT
does not apply to the forming of the metals cadmium, chromium, gallium,
germanium, indium, lithium, manganese, neodymium, or praseodymium.
b) General Definitions. The Board incorporates by reference 40 CFR 471.02 (2003). This incorporation includes no later amendments or editions.
c) Compliance Dates. The Board incorporates by reference 40 CFR 471.03 (2003). This incorporation includes no later amendments or editions.
