The reduction efficiency or parts per million by volume shall be established by an initial performance test to be completed no later than 180 days after the initial startup of the approved control system using the test methods specified in sub. (5) (d).
a) If a boiler or process heater is used as the control device, the landfill gas stream shall be introduced into the flame zone.
b) The control device shall be operated within the parameter ranges established during the initial or most recent performance test. The operating parameters to be monitored are specified in sub. (7).
