TITLE 40--PROTECTION OF ENVIRONMENT
CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
PART 437_THE CENTRALIZED WASTE TREATMENT POINT SOURCE CATEGORY--Table
of Contents
Sec. 437.2 General definitions.
As used in this part:
(a) The general definitions and abbreviations in 40 CFR part 401
apply to this part.
(b) Alternative effluent limitations or pretreatment standards mean
effluent limitations determined on a case-by-case basis under section
402(a)(1) of the CWA or pretreatment standards developed as local limits
by the control authority under 40 CFR Sec. 403.6(c) that apply to the
discharge of wastewater subject to this provision. The permit writer (or
control authority) will calculate these limitations or standards using a
``building block'' approach or the ``combined wastestream formula.''
Under this approach, the permit writer (or control authority) will
develop flow-weighted effluent limitations or standards for the treated
combined wastestream by applying the limitations or standards in 40 CFR
subchapter N that would otherwise apply to a particular wastestream
received from off-site if the wastestream were treated and discharged
from the facility at which it was generated.
(c) Centralized waste treatment (CWT) facility means any facility
that treats (for disposal, recycling or recovery of material) any
hazardous or non-hazardous industrial wastes, hazardous or non-hazardous
industrial wastewater, and/or used material received from off-site.
``CWT facility'' includes both a facility that treats waste received
exclusively from off-site and a facility that treats wastes generated
on-site as well as waste received from off-site. For example, an organic
chemical manufacturing plant may, in certain circumstances, be a CWT
facility if it treats industrial wastes received from offsite as well as
industrial waste generated at the organic chemical manufacturing plant.
CWT facilities may also include re-refiners and may be owned by the
federal government.
(d) Centralized waste treatment wastewater means any wastewater
generated as a result of CWT activities. CWT wastewater sources may
include, but are not limited to: liquid waste receipts, solubilization
water, used oil emulsion-breaking wastewater, tanker truck/drum/roll-off
box washes, equipment washes, air pollution control scrubber blow-down,
laboratory-derived wastewater, on-site landfill wastewaters, and
contaminated storm water.
(e) Contaminated storm water means storm water which comes in direct
contact with CWT wastes, the waste handling and treatment areas, or
other centralized waste treatment wastewater as defined in paragraph (d)
of this section.
(f) Discharger means a facility that discharges wastewater directly
to waters of the United States or introduces wastewater to a publicly-
owned treatment works.
(g) Dry means not producing a wastewater.
(h) Equivalent treatment means a wastewater treatment system that
achieves comparable pollutant removals to the applicable treatment
technology selected as the basis for the limitations and pretreatment
standards. Comparable removals may be demonstrated through literature,
treatability tests, or self-monitoring data.
(i) Fuel blending means the process of combining waste, wastewater,
or used material for the purpose of regenerating a fuel for reuse.
However, fuel blending may be loosely applied to any process where
recovered hydrocarbons are combined as a fuel product where some
pretreatment operations generate wastewater.
(j) High temperature metals recovery means a metals recovery process
in which solid forms of metal-containing materials are processed with a
heat-based pyrometallurgical technology to produce a metal product.
(k) Marine generated waste means any waste, wastewater, and/or used
material generated as part of the normal
[[Page 363]]
maintenance and operation of a ship, boat, or barge operating on inland,
coastal, or open waters, or while berthed.
(l) Metal-bearing wastes means wastes and/or used materials from
manufacturing or processing facilities or other commercial operations
that contain significant quantities of metal pollutants, but not
significant quantities of oil and grease (generally less than 100 mg/L).
Examples of these wastes are spent electroplating baths and sludges,
metal-finishing rinse water and sludges, chromate wastes, blow-down
water and sludges from air pollution control, spent anodizing solutions,
incineration air pollution control wastewaters, waste liquid mercury,
cyanide containing wastes greater than 136 mg/L, and waste acids and
bases with or without metals.
(m) Multiple wastestream CWT facility means a CWT facility which
accepts waste in more than one CWT subcategory (metals, oils, or
organics) and combines any portion of these different subcategory wastes
at any point prior to the compliance discharge sampling location.
(n) Off-site means outside the boundaries of a facility.
(o) Oily absorbent recycling means the process of recycling oil-
soaked or contaminated disposable rags, paper, or pads for the purpose
of regenerating a fuel for reuse.
(p) Oily wastes means wastes and/or used materials that contain oil
and grease (generally at or in excess of 100 mg/L) from manufacturing or
processing facilities or other commercial operations. Examples of these
wastes are used oils, oil-water emulsions or mixtures, lubricants,
coolants, contaminated groundwater clean-up from petroleum sources, used
petroleum products, oil spill clean-up, bilge water, rinse/wash waters
from petroleum sources, interceptor wastes, off-specification fuels,
underground storage tank remediation waste, and tank clean out from
petroleum or oily sources.
(q) On-site means within the boundaries of a facility. A facility
may encompass land areas that are bisected by public thoroughfares but
are under the control of a common owner.
(r) Organic wastes means wastes and/or used materials that contain
organic pollutants, but not a significant quantity of oil and grease
(generally less than 100 mg/L) from manufacturing or processing
facilities or other commercial operations. Examples of these wastes are
landfill leachate, contaminated groundwater clean-up from non-petroleum
sources, solvent-bearing wastes, off-specification organic product,
still bottoms, byproduct glycols, wastewater from paint washes,
wastewater from adhesives and/or epoxies, wastewater from chemical
product operations, and tank clean-out from organic, non-petroleum
sources.

(x) Re-refining means the processing of used oil using distillation,
hydrotreating, and/or other treatment employing acid, caustic, solvent,
clay and/or chemicals in order to produce high quality base stock for
lubricants or other petroleum products.
(y) Recovery means the recycling or processing of a waste,
wastewater or used material such that the material, or a portion
thereof, may be reused or converted to a raw material, intermediate, or
product. Recovery does not include the re-use of treated or untreated
wastewater in place of potable or pure water in industrial processes
such as the use of secondary POTW effluents as non-contact cooling
water, storm water in place of process water, or the re-use of spent
chemicals in place of virgin treatment chemicals.
(z) Solidification means the addition of sorbents to convert liquid
or semi-liquid waste to a solid by means of adsorption, absorption or
both. The process is usually accompanied by stabilization.
(aa) Solvent recovery includes fuel blending operations and the
recycling of spent solvents through separation of solvent mixtures in
distillation columns. Solvent recovery may require an additional,
pretreatment step prior to distillation.
(bb) Stabilization means a waste process that decreases the mobility
of waste constituents by means of a chemical reaction. For the purpose
of this rule, chemical precipitation is not a technique for
stabilization.
(cc) Treatment means any method, technique, or process designed to
change the physical, chemical or biological character or composition of
any metal-bearing, oily, or organic wastes to neutralize such wastes; to
render such wastes amenable to discharge; or to recover energy or
recover metal, oil, or organic content from the wastes. Treatment does
not include (a) the re-use of treated or untreated wastewater in place
of potable or pure water in industrial processes such as the use of
secondary POTW effluents as non-contact cooling water or storm water in
place of process water or (b) the re-use of treated or untreated spent
chemicals (such as pickle liquor) as treatment chemicals.

come in direct contact with CWT wastes, the waste handling and treatment
areas, or other CWT wastewater that is defined in paragraph (d) of this
section.
(ee) Used oil filter recycling means crushing and draining of used
oil filters of entrained oil and/or shredding and separation of used oil
filters.
(ff) Waste includes aqueous, non-aqueous, and solid waste,
wastewater, and/or used material.
