Section 307.2400Â General
Provisions
a)        General Definitions. The Board incorporates by reference 40
CFR 414.10 (2005). This incorporation includes no later amendments or
editions.
b)Â Â Â Â Â Â Â Â Applicability
1)Â Â Â Â Â Â Â Â This Subpart O applies to process wastewater discharges from
all establishments or portions of establishments that manufacture the organic
chemicals, plastics, and synthetic fibers (OCPSF) products or product groups that
are covered by Sections 307.2402 through 307.2408 and which are included in the
following SIC major groups, as defined in the Standard Industrial
Classification Manual, incorporated by reference in 35 Ill. Adm. Code 310.107:
A)Â Â Â Â Â Â Â SIC 2821: Plastic materials, synthetic resins, and
nonvulcanizable elastomers.
B)Â Â Â Â Â Â Â SIC 2823: Cellulosic man-made fibers.
C)Â Â Â Â Â Â Â SIC 2824: Synthetic organic fibers, except cellulosic.
D)Â Â Â Â Â Â Â SIC 2865: Cyclic crudes and intermediates, dyes, and organic
pigments.
E)Â Â Â Â Â Â Â SIC 2869: Industrial organic chemicals, not elsewhere
classified.
2)Â Â Â Â Â Â Â Â This Subpart O applies to wastewater discharges from OCPSF
research and development, pilot plant, technical service, and laboratory bench-scale
operations if such operations are conducted in conjunction with and related to
existing OCPSF manufacturing activities at the plant site.
3)Â Â Â Â Â Â Â Â Notwithstanding subsection (b)(1), this Subpart O does not
apply to discharges resulting from the manufacture of OCPSF products if the
products are included in the following SIC subgroups, as defined in the
Standard Industrial Classification Manual, incorporated by reference in 35 Ill.
Adm. Code 310.107, and if the products have in the past been reported by the
establishment under these subgroups and not under the SIC groups listed in
subsection (b)(1):
A)Â Â Â Â Â Â Â SIC 2843085: Bulk surface active agents.
B)Â Â Â Â Â Â Â SIC 28914: Synthetic resin and rubber adhesives.
C)Â Â Â Â Â Â Â Chemicals and Chemical Preparations Not Elsewhere Classified:
i)Â Â Â Â Â Â Â Â Â SIC 2899568: Sizes, all types.
ii)Â Â Â Â Â Â Â Â SIC 2899597: Other industrial chemical specialties, including
fluxes, plastic wood preparations, and embalming fluids.
D)Â Â Â Â Â Â Â SIC 2911058: Aromatic hydrocarbons manufactured from purchased
refinery products.
E)Â Â Â Â Â Â Â SIC 2911632: Aliphatic hydrocarbons manufactured from purchased
refinery products.
4)Â Â Â Â Â Â Â Â Notwithstanding subsection (b)(1), this Subpart O does not
apply to any discharges for which a different set of previously promulgated
standards in this Part apply, unless the facility reports OCPSF products under
SIC codes 2865, 2869, or 2821, as defined in the Standard Industrial
Classification Manual, incorporated by reference in 35 Ill. Adm. Code 310.107,
and the facility's OCPSF wastewaters are discharged separately to a POTW.
5)Â Â Â Â Â Â Â Â This Subpart O does not apply to any process wastewater
discharge from the manufacture of organic chemical compounds solely by
extraction from plant and animal raw materials or by fermentation processes.
6)Â Â Â Â Â Â Â Â Discharges of chromium, copper, lead, nickel, and zinc in
"complexed metal-bearing waste streams," listed in Section 307.2491,
are not subject to this Subpart O.
7)Â Â Â Â Â Â Â Â Non-Amenable Cyanide
A)Â Â Â Â Â Â Â Discharges of cyanide in "cyanide-bearing waste streams,"
listed in Section 307.2490, are not subject to the cyanide limitations of this
Subpart O if both of the following occur:
i)Â Â Â Â Â Â Â Â Â The Control Authority determines that the cyanide limitations
are not achievable due to elevated levels of non-amenable cyanide (i.e.,
cyanide that is not oxidized by chlorine treatment) that result from the
unavoidable complexing of cyanide at the process source of the cyanide-bearing
waste stream, and
ii)Â Â Â Â Â Â Â Â The control authority establishes an alternative total
cyanide or amenable cyanide limitation that reflects the best available
technology economically achievable.
B)Â Â Â Â Â Â Â The control authority must base its determination made pursuant
to subsection (b)(7)(A) on a review of the relevant engineering, production,
and sampling and analytical information at its disposal, including measurements
of both total and amenable cyanide in the waste stream.
C)Â Â Â Â Â Â Â The control authority must set forth its determination made
pursuant to subsection (b)(7)(A) in a written analysis of the extent of
complexing in the waste stream and its impact on cyanide treatability, based on
the information at its disposal.
D)Â Â Â Â Â Â Â Alternative cyanide discharge limitation determinations made
pursuant to this subsection (b)(7) are subject to the limitations of Section
307.1103. However, Section 307.1103 may not be used to allow a discharge of
total cyanide greater than that otherwise allowed by this subsection (b)(7).
8)Â Â Â Â Â Â Â Â Allowances for Non-Metal-Bearing Waste Streams
A)Â Â Â Â Â Â Â The control authority must establish discharge limitations for
lead and zinc for waste streams not listed in Section 307.2490 and not
otherwise determined to be "metal-bearing waste streams" if it
determines that the wastewater metals contamination is due to background levels
that are not reasonably avoidable, from such sources as intake water, corrosion
of materials of construction, or contamination of raw materials.
B)Â Â Â Â Â Â Â The control authority must base its determination made pursuant
to subsection (b)(8)(A) on a review of relevant plant operating conditions,
process chemistry, engineering, and sampling and analytical information.
C)Â Â Â Â Â Â Â The control authority must set forth its determination made
pursuant to subsection (b)(8)(A) in a written analysis of the sources and
levels of the metals, based on the information at its disposal.
D)Â Â Â Â Â Â Â The control authority may establish limitations for lead and
zinc for non-metal-bearing waste streams for the purposes of subsection
(b)(8)(A) between the following levels:
i)Â Â Â Â Â Â Â Â Â The lowest level that the control authority determines, based
on best professional judgment, can be reliably measured; and
ii)Â Â Â Â Â Â Â Â The concentration of such metals present in the waste streams,
but not to exceed the applicable limitations contained in Sections 307.2401
through 307.2407.
iii)Â Â Â Â Â Â Â For zinc, the applicable limitations that the discharge must
not exceed are those appearing in the tables in Sections 307.2401 through
307.2407, not the alternative limitations for rayon fiber manufacture by the
viscose process, as set forth in footnote 2 to the table in 40 CFR 414.25,
incorporated by reference at Section 307.2401(c)(1), or the alternative
limitations for acrylic fiber manufacture by the zinc chloride/solvent process,
as set forth in footnote 2 to the table in 40 CFR 414.35, each incorporated by
reference at Section 307.2402(c)(1).
E)Â Â Â Â Â Â Â The limitations for individual dischargers must be set on a
mass basis, by multiplying the concentration allowance established by the
control authority times the process wastewater flow from the individual waste
streams in which incidental metals are present.
c)        Compliance Date. All dischargers subject to a pretreatment
standard for existing sources in this Subpart O must have complied with the
standard by November 5, 1990.
