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.

During conditioning, hazardous waste and raw materials having the same metals content as will be fed during the compliance test shall be fed at the feed rates that will be fed during the compliance test. NR 666.103(3)(c)3.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 666.103(3)(c)3.b.b. Prior to obtaining test data for purposes of demonstrating compliance with the applicable emissions standards of ss. NR 666.104 to 666.107 or establishing limits on operating parameters under this section, the facility shall operate under compliance test conditions for a sufficient period to reach steady-state operations. Industrial furnaces that recycle collected particulate matter back into the furnace and that comply with subd. 2. a. or b., however, need not reach steady state conditions with respect to the flow of metals in the system prior to beginning compliance testing for metals. NR 666.103(3)(c)3.c.c. Compliance test data on the level of an operating parameter for which a limit shall be established in the certification of compliance 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 par. (a). NR 666.103(3)(d)(d) Certification of compliance. Within 90 days of completing compliance testing, the owner or operator shall certify to the department compliance with the emissions standards of ss. NR 666.104 (2), (3) and (5), 666.105, 666.106, 666.107 and sub. (1) (e) 1. d. The certification of compliance shall include all of the following information:
