Current through June 24, 2024
(1) DRE STANDARD.
(a)
General.
Except as
				  provided in par. (c), a boiler or industrial furnace burning hazardous waste
				  shall achieve a destruction and removal efficiency (DRE) of 99.99% for all
				  organic hazardous constituents in the waste feed. To demonstrate conformance
				  with this requirement, 99.99% DRE shall be demonstrated during a trial burn for
				  each principal organic hazardous constituent (POHC) designated (under par. (b))
				  in its license for each waste feed. DRE is determined for each POHC from the
				  following equation:
See

where:
Win = Mass feed rate of one principal organic hazardous
					 constituent (POHC) in the hazardous waste fired to the boiler or industrial
					 furnace
Wout = Mass emission rate of the same POHC present in stack
					 gas prior to release to the atmosphere
(b)
Designation of POHCs.
Principal organic hazardous constituents (POHCs) are those compounds for which
				  compliance with the DRE requirements shall be demonstrated in a trial burn in
				  conformance with procedures prescribed in s.
				  NR
				  670.066. One or more POHCs shall be designated by the
				  department for each waste feed to be burned. POHCs shall be designated based on
				  the degree of difficulty of destruction of the organic constituents in the
				  waste and on their concentrations or mass in the waste feed considering the
				  results of waste analyses submitted with the feasibility and plan of operation
				  report. POHCs are most likely to be selected from among those compounds listed
				  in ch. NR 661 Appendix VIII that are also present in the normal waste feed.
				  However, if the applicant demonstrates to the department's satisfaction in
				  writing that a compound not listed in ch. NR 661 Appendix VIII or not present
				  in the normal waste feed is a suitable indicator of compliance with the DRE
				  requirements, that compound may be designated as a POHC. Such POHCs need not be
				  toxic or organic compounds.
(c)
Dioxin-listed waste.
A boiler or industrial furnace burning
				  hazardous waste containing (or derived from) EPA hazardous waste numbers F020,
				  F021, F022, F023, F026 or F027 shall achieve a destruction and removal
				  efficiency (DRE) of 99.9999% for each POHC designated (under par. (b)) in its
				  license. This performance shall be demonstrated on POHCs that are more
				  difficult to burn than tetra-, penta- and
				  hexachlorodibenzo-
p
-dioxins and dibenzofurans. DRE is
				  determined for each POHC from the equation in par. (a). In addition, the owner
				  or operator of the boiler or industrial furnace shall notify the department of
				  intent to burn EPA hazardous waste numbers F020, F021, F022, F023, F026 or
				  F027.
(d)
Automatic waiver
				  of DRE trial burn.
Owners and operators of boilers operated under the
				  special operating requirements provided by s.
				  NR
				  666.110 are considered to be in compliance with the
				  DRE standard of par. (a) and are exempt from the DRE trial burn.
(e)
Low risk waste.
Owners
				  and operators of boilers or industrial furnaces that burn hazardous waste in
				  compliance with s.
				  NR
				  666.109(1) are considered to be in
				  compliance with the DRE standard of par. (a) and are exempt from the DRE trial
				  burn.
