Standards of Performance for Large Municipal Waste Combustors for Which Construction Is Commenced After September 20, 1994 or for Which Modification or Reconstruction Is Commenced After June 19, 1996 and Emission Guidelines and Compliance Times for Large Municipal Waste Combustors That Are Constructed on or Before September 20, 1994

We are amending the standards of performance for large municipal waste combustors (MWC) by extending the time during which such units will be excused from compliance with the emission limits for carbon monoxide due to certain types of malfunctions. Since the compliance and performance testing provisions in the emissions guidelines for large MWC reference the compliance and performance testing provisions in the standards of performance, this amendment to the standards has the effect of amending both the standards and the guidelines.
