Generators of listed hazardous wastes must test their waste, or waste extract using
the TCLP, or use knowledge of the waste to determine if the waste is restricted from land
disposal. Generators of characteristic hazardous wastes must test their wastes using EP
toxicity test, or use knowledge of the waste to determine if the waste is restricted from land
disposal. If the generator determines that the waste is restricted from land disposal (a
“restricted” waste) and does not meet applicable treatment standards under OAC Rule
3745-59-40 to 44 or prohibition levels under OAC Rule 3745-59-32, then they must fulfill
certain notification requirements to the TSDF with each shipment of the waste (see OAC
Rule 3745-59-07(A)(1)). This notification must include the treatment standard or
prohibition level, or the specified treatment technology if listed in Table 1 of OAC Rule
3745-59-42, and waste analysis data, if available. If the generator determines that the
waste is restricted but does meet the treatment standard or prohibition level, then they
must fulfill certain notification and certification requirements with each shipment of the
waste (see OAC Rule 3745-59-07(A)(2)). This notification must also include the specified
treatment standard, prohibition level, or specified treatment technology and any available
waste analysis data. All notifications, certifications, waste analysis data, and information
supporting knowledge of any waste treated, stored or disposed of on-site or off-site must
be maintained in the facility file for at least five years.
There are a few additional waste analysis requirements for generators of liquid
wastes Generators must test or use knowledge of the waste to determine if the pH is less
than or equal to 2. If the pH is less than or equal to 2, it is restricted from land disposal.
If a generators liquid waste contains polychlorinated biphynels (PCBs) or is primarily water
containing hazardous organic constituents (HOCs) listed in the Appendix to OAC Rule
3745-59-32, the generator must test the waste or use knowledge of the waste to determine
if it equals or exceeds prohibition levels.
Treatment facilities must test their treatment residues in accordance with the
frequency specified in the WAP. Pursuant to OAC Rule 3745-59-07(B), for wastes with
treatment standards expressed as concentrations in the waste extract, the facility must test
the treatment residue with the TCLP to determine if the treatment residue or extract meet
treatment standards. For wastes with treatment standards expressed as concentrations
in the waste, the facility must test treatment residues to ensure treatment standards are
meet. For wastes prohibited under OAC Rule 3745-59-32 but without treatment standards
under OAC Rule 3745-59-40 to 44, the facility must test the treatment residue in
accordance with the generator testing requirements in OAC Rule 3745-59-32 to determine
if the treatment residues meet treatment standards of OAC Rule 3745-59-32. If the waste
is to be further managed at another treatment or storage facility, the original treatment
facility must fulfill the notification and certification requirements of the generator. If the
