Operating Requirements
Before adding hazardous waste,
the owner or operator must bring his thermal treatment process to steady state
(normal) conditions of operation, including steady state operating
temperature-using auxiliary fuel or other means, unless the process is a
noncontinuous (batch) thermal treatment process which requires a complete
thermal cycle to treat a discrete quantity of hazardous waste.
