Compliance wiht the MACT I provisions of the EPA Cluster Rules requires treatment of selected foul condensate streams from digesters and evaporators in kraft pulp mills to remove methanol. The MACT i rules also require collection and treatment of vapors from washer hoods. Vapors from deckeer hoods must also be cooected if contaminated condensate having a methanol concentration greater than 400 mg/l is used as wash water on decker showers. The latter requirements may be waived if condensates are segregated in a manner which makes the "Clean Condensate Alternative" applicable.
