NR 666.102(5)(f)(f) Measuring parameters and establishing limits based on trial burn data. NR 666.102(5)(f)1.1. ‘General requirements.’ As specified in pars. (b) to (e), each operating parameter shall be measured, and license limits on the parameter shall be established, according to either of the following procedures: NR 666.102(5)(f)1.a.a. A parameter may be measured and recorded on an instantaneous basis (i.e., the value that occurs at any time) and the license limit specified as the time-weighted average during all valid runs of the trial burn. NR 666.102(5)(f)1.b.b. 1)The limit for a parameter may be established and continuously monitored on an hourly rolling average basis defined as follows: a) A continuous monitor is one which continuously samples the regulated parameter without interruption, and evaluates the detector response at least once each 15 seconds, and computes and records the average value at least every 60 seconds.
b) An hourly rolling average is the arithmetic mean of the 60 most recent 1-minute average values recorded by the continuous monitoring system.
2) The license limit for the parameter shall be established based on trial burn data as the average over all valid test runs of the highest hourly rolling average value for each run.
NR 666.102(5)(f)2.2. ‘Rolling average limits for carcinogenic metals and lead.’ Feed rate limits for the carcinogenic metals (i.e., arsenic, beryllium, cadmium and chromium) and lead may be established either on an hourly rolling average basis as prescribed by subd. 1. or on (up to) a 24 hour rolling average basis. If the owner or operator elects to use an average period from 2 to 24 hours: NR 666.102(5)(f)2.a.a. The feed rate of each metal shall be limited at any time to 10 times the feed rate that would be allowed on an hourly rolling average basis. 1) A continuous monitor is one which continuously samples the regulated parameter without interruption, and evaluates the detector response at least once each 15 seconds, and computes and records the average value at least every 60 seconds.
2) The rolling average for the selected averaging period is defined as the arithmetic mean of one hour block averages for the averaging period. A one hour block average is the arithmetic mean of the one minute averages recorded during the 60-minute period beginning at one minute after the beginning of preceding clock hour.
NR 666.102(5)(f)2.c.c. The license limit for the feed rate of each metal shall be established based on trial burn data as the average over all valid test runs of the highest hourly rolling average feed rate for each run. NR 666.102(5)(f)3.3. ‘Feed rate limits for metals, total chloride and chlorine, and ash.’ Feed rate limits for metals, total chlorine and chloride, and ash are established and monitored by knowing the concentration of the substance (i.e., metals, chloride and chlorine, and ash) in each feedstream and the flow rate of the feedstream. To monitor the feed rate of these substances, the flow rate of each feedstream shall be monitored under the continuous monitoring requirements of subds. 1. and 2. 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)1.1. ‘Fugitive emissions.’ Fugitive emissions shall be controlled by one of the following: 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)1.1. The owner or operator shall monitor and record all of the following, at a minimum, while burning hazardous waste:
