				  Waste Characterization Report.
a.
				  Determination of the proper landfill class for disposal of a waste stream is
				  based on the chemical and physical properties of the waste and not on the
				  source of generation of the waste. To determine the class of landfill required
				  for proper disposal of a waste stream, the permittee shall submit to the
				  Department a waste characterization report. The waste characterization report
				  shall consist of a comprehensive analytical evaluation of the chemical and
				  physical nature of each waste stream. Hazardous wastes as defined in
				  R.61-79, Hazardous Waste
				  Management Regulations shall not be disposed of in the landfills under the
				  purview of this regulation. The wastes acceptable for disposal in a Class One
				  landfill, and waste items listed in Appendix I are exempt from the waste
				  characterization process outlined in this regulation. Class Three landfills
				  shall adhere to their approved Special Waste Analysis and Implementation Plan
				  (SWAIP), pursuant to S.C. Code Section
				  44-96-390
				  which shall be deemed to be in compliance with this Section.
b. The toxicity characteristic leaching
				  procedure (TCLP) (USEPA method 1311) shall be used to obtain all extracts for
				  the purpose of characterizing a waste stream proposed for disposal in a solid
				  waste landfill.
c. The analytical
				  results of the TCLP shall be compared to the MCLs in South Carolina
				  R.61-58 State Primary Drinking
				  Water Regulation to determine the appropriate class landfill in which the waste
				  stream may be disposed. If no MCL exists for a parameter, then those drinking
				  water risk-based concentrations recognized by EPA Region IV shall be used to
				  determine the appropriate class landfill for the waste. For those parameters
				  where no MCL or Region IV number exists, the Department, using input from the
				  permittee, will develop an appropriate number for determining the landfill
				  class for disposal of that waste stream.
d. Unless otherwise exempted in this
				  regulation, all wastes shall be characterized in accordance with the following
				  schedule:
(1) A minimum of every three years
				  using certified knowledge of the process by which the waste stream was
				  generated;
(2) At a minimum of
				  every six years using analytical test data from the TCLP;
(3) According to a Department approved
				  alternate schedule based on the variability or non-variability noted in
				  previous sampling events or other factors that affect the predictability of
				  waste characteristics;
(4) When the
				  process or raw materials used in the process that generates the waste changes
				  significantly enough to alter the chemical makeup or chemical ratios of the
				  waste stream; and,
(5) When a new
				  waste stream is proposed for disposal.
e. Waste streams not listed in Appendix I,
				  that demonstrate properties similar to the waste listed on Appendix I, may be
				  exempted from testing as determined by the Department on a case-by-case basis.
				  Requests for an exemption from testing, along with technical rationale for the
				  exemption, shall be submitted to the Department in writing.
f. The Department will provide current forms
				  and guidance documents needed for the successful completion of the waste
				  characterization process. All analytical results from the characterization
				  process shall be submitted to the Department on these forms or in a format
				  approved by the Department.
