1. (a) The concentration of carbon monoxide contained in the gases discharged to the atmosphere from a MWC unit shall not exceed the following limits for each type of affected equipment:

   MUNICIPAL WASTE COMBUSTOR OPERATING LIMITS
   Municipal waste combustor technology	Carbon monoxide emissions level (ppm by volume)a	Averaging Time (hours)b
   Mass burn waterwall	100	4
   Mass burn refractory	100	4
   Mass burn rotary refractory	100	24
   Mass burn rotary waterwall	250	24
   Modular starved air	50	4
   Modular excess air	50	4
   Refuse-derived fuel stoker	200	24
   Fluidized bed, mixed fuel(wood/refuse-derived fuel)/_touchup	200	24ccc
   Bubbling fluidized bed combustor	100	4
   Circulating fluidized bed combustor	100	4
   Pulverized coal/refuse-derived fuel mixed fuel-fired combustor	150	4
   Spreader stoker coal/refuse-derived fuel mixed fuel-fired combustor	200	24

   Spreader stoker fixed floor refuse-derived fuel-fired combustor/100 percent coal capable	250	24ccc
   a Measured at the combustor outlet in conjunction with a measurement of oxygen concentration, corrected to 7 percent oxygen, dry basis. Calculated as an arithmetic average.
   b Averaging times are 4-hour or 24-hour block averages.
   c 24-hour block average, geometric mean.

2. (b) An owner or operator of a MWC shall comply with all provisions specified in 40 CFR 60.53b(b) and (c), which is hereby incorporated by reference as it exists on November 6, 2006.
