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. 38, September 20, 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.
