(2). NR 440.76(7)(a)2.2. You may not operate your municipal waste combustion unit so that the temperature at the inlet of the particulate matter control device exceeds 17°C above the maximum demonstrated temperature of the particulate matter control device, based on a 4-hour block average, as specified in sub. (2). NR 440.76(7)(a)3.3.
