NR 666.102(5)(f)4.a.a. If compliance with all applicable emissions standards of ss. NR 666.104 to 666.107 is not demonstrated simultaneously during a set of test runs, the operating conditions of additional test runs required to demonstrate compliance with remaining emissions standards shall be as close as possible to the original operating conditions.

NR 666.102(5)(f)4.b.b. Prior to obtaining test data for purposes of demonstrating compliance with the emissions standards of ss. NR 666.104 to 666.107 or establishing limits on operating parameters under this section, the facility shall operate under trial burn conditions for a sufficient period to reach steady-state operations. The department may determine, however, that industrial furnaces that recycle collected particulate matter back into the furnace and that comply with an alternative implementation approach for metals under s. NR 666.106 (6) need not reach steady state conditions with respect to the flow of metals in the system prior to beginning compliance testing for metals emissions.

NR 666.102(5)(f)4.c.c. Trial burn data on the level of an operating parameter for which a limit shall be established in the license shall be obtained during emissions sampling for the pollutant or pollutants (i.e., metals, PM, HCl/Cl2, organic compounds) for which the parameter shall be established as specified by this subsection.

NR 666.102(5)(g)1.a.a. Keeping the combustion zone totally sealed against fugitive emissions.

NR 666.102(5)(g)1.b.b. Maintaining the combustion zone pressure lower than atmospheric pressure.

NR 666.102(5)(g)1.c.c. An alternate means of control demonstrated (with the feasibility and plan of operation report) to provide fugitive emissions control equivalent to maintenance of combustion zone pressure lower than atmospheric pressure.

NR 666.102(5)(g)2.2. ‘Automatic waste feed cutoff.’ A boiler or industrial furnace shall be operated with a functioning system that automatically cuts off the hazardous waste feed when operating conditions deviate from those established under this section. The department may limit the number of cutoffs per an operating period on a case-by-case basis. In addition, all of the following conditions shall be met:

NR 666.102(5)(g)2.a.a. The license limit for (the indicator of) minimum combustion chamber temperature shall be maintained while hazardous waste or hazardous waste residues remain in the combustion chamber.

NR 666.102(5)(g)2.b.b. Exhaust gases shall be ducted to the air pollution control system operated in accordance with the license requirements while hazardous waste or hazardous waste residues remain in the combustion chamber.

NR 666.102(5)(g)2.c.c. Operating parameters for which license limits are established shall continue to be monitored during the cutoff, and the hazardous waste feed may not be restarted until the levels of those parameters comply with the license limits. For parameters that may be monitored on an instantaneous basis, the department shall establish a minimum period of time after a waste feed cutoff during which the parameter may not exceed the license limit before the hazardous waste feed may be restarted.

NR 666.102(5)(g)3.3. ‘Changes.’ A boiler or industrial furnace shall cease burning hazardous waste when changes in combustion properties, or feed rates of the hazardous waste, other fuels or industrial furnace feedstocks, or changes in the boiler or industrial furnace design or operating conditions deviate from the limits as specified in the license.

NR 666.102(5)(h)1.a.a. If specified by the license, feed rates and composition of hazardous waste, other fuels and industrial furnace feedstocks, and feed rates of ash, metals, and total chloride and chlorine.

NR 666.102(5)(h)1.b.b. If specified by the license, carbon monoxide (CO), hydrocarbons (HC) and oxygen on a continuous basis at a common point in the boiler or industrial furnace downstream of the combustion zone and prior to release of stack gases to the atmosphere in accordance with operating requirements specified in par. (b) 2. CO, HC and oxygen monitors shall be installed, operated and maintained in accordance with methods specified in ch. NR 666 Appendix IX.

NR 666.102(5)(h)1.c.c. Upon the request of the department, sampling and analysis of the hazardous waste (and other fuels and industrial furnace feedstocks as appropriate), residues and exhaust emissions shall be conducted to verify that the operating requirements established in the license achieve the applicable standards of ss. NR 666.104, 666.105, 666.106 and 666.107.

NR 666.102(5)(h)3.3. The boiler or industrial furnace and associated equipment (pumps, values, pipes, fuel storage tanks, etc.) shall be subjected to thorough visual inspection when it contains hazardous waste, at least daily for leaks, spills, fugitive emissions and signs of tampering.

NR 666.102(5)(h)4.4. The automatic hazardous waste feed cutoff system and associated alarms shall be tested at least once every 7 days when hazardous waste is burned to verify operability, unless the applicant demonstrates to the department that weekly inspections will unduly restrict or upset operations and that less frequent inspections will be adequate. At a minimum, operational testing shall be conducted at least once every 30 days.

NR 666.102(5)(h)5.5. These monitoring and inspection data shall be recorded and the records shall be placed in the operating record required by s. NR 664.0073.

NR 666.102(5)(i)(i) Direct transfer to the burner. If hazardous waste is directly transferred from a transport vehicle to a boiler or industrial furnace without the use of a storage unit, the owner and operator shall comply with s. NR 666.111.

NR 666.102(5)(j)(j) Recordkeeping. The owner or operator shall keep in the operating record of the facility all information and data required by this section for a minimum of 5 years.

NR 666.102(5)(k)(k) Closure. At closure, the owner or operator shall remove all hazardous waste and hazardous waste residues (including, but not limited to, ash, scrubber waters and scrubber sludges) from the boiler or industrial furnace.
