eCFR Subpart YYYY  [ecfr.gov]
This subpart applies to:
- New stationary combustion turbines with a rated peak power output of at least 1.0 MW, and located at a Major Source of HAPs.
Not subject to this subpart:
- Existing turbines.
- Emergency-use turbines.
- Turbines located on the North Slope of Alaska.
- Turbine engine test cells/stands.
- Duct burners and waste heat recovery units.
On Aug 18, 2004, EPA stayed the effectiveness of the emission and operating limitations for lean-premixed gas-fired and diffusion flame gas-fired turbines. These turbines must comply only with the Initial Notification requirements in 63.6145 until EPA takes final action on the stay. See the Federal Register document below. |
