35 Ill. Adm. Code 728.103
Dilution Prohibited as a Substitute for Treatment
Section 728
Section 728.103 Dilution
Prohibited as a Substitute for Treatment
a) Except as provided in subsection (b), no generator,
transporter, handler, or owner or operator of a treatment, storage, or disposal
facility must in any way dilute a restricted waste or the residual from
treatment of a restricted waste as a substitute for adequate treatment to
achieve compliance with Subpart D, to circumvent the effective date of a
prohibition in Subpart C, to otherwise avoid a prohibition in Subpart C, or to
circumvent a land disposal restriction imposed by RCRA section 3004 (42 USC
6924).
b) Dilution of waste that is hazardous only because it exhibits a
characteristic of hazardous waste in a treatment system that treats wastes
subsequently discharged to a water of the State pursuant to an NPDES permit
issued under 35 Ill. Adm. Code 309, that treats wastes in a CWA-equivalent
treatment system, or that treats wastes for purposes of pretreatment
requirements under 35 Ill. Adm. Code 310 is not impermissible dilution for
purposes of this Section, unless a method other than DEACT has been specified
in Section 728.140 as the treatment standard or unless the waste is a D003
reactive cyanide wastewater or nonwastewater.
c) Combustion of waste designated by any of the USEPA hazardous
waste numbers listed in Appendix J is prohibited, unless the waste can be
demonstrated to comply with one or more of the following criteria at the point
of generation or after any bona fide treatment, such as cyanide destruction
prior to combustion (unless otherwise specifically prohibited from combustion):
1) The waste contains hazardous organic constituents or cyanide
at levels exceeding the constituent-specific treatment standard found in
Section 728.148;
2) The waste consists of organic, debris-like materials (e.g.,
wood, paper, plastic, or cloth) contaminated with an inorganic metal-bearing
hazardous waste;
3) The waste has reasonable heating value, such as greater than
or equal to 5,000 Btu per pound, at the point of generation;
4) The waste is co-generated with wastes for which combustion is
a required method of treatment;
5) The waste is subject to any federal or state requirements
necessitating reduction of organics (including biological agents); or
6) The waste contains greater than one percent Total Organic
Carbon (TOC).
d) It is a form of impermissible dilution, and therefore
prohibited, to add iron filings or other metallic forms of iron to
lead-containing hazardous wastes in order to achieve any land disposal
restriction treatment standard for lead. Lead-containing wastes include D008
wastes (wastes exhibiting a characteristic due to the presence of lead), all
characteristic wastes containing lead as an underlying hazardous constituent,
listed wastes containing lead as a regulated constituent, and hazardous media
containing any of the aforementioned lead-containing wastes.
