Description of the source (including control equipment). Please see the attachments for source or process flow diagram: The Valley Power Plant Boilers 1, 2, 3, and 4 are Riley Stoker, dry bottom, wall-fired, pulverized coal-fired boilers which currently fire western bituminous coals. These units are also permitted to fire natural gas and propane for unit startup, flame stabilization, and supplemental firing. In 1994, low Nox burners were installed on all four boilers, and the original electrostatic precipitators on all four boilers were replaced with high efficiency fabric filter baghouses.
