Electric Power Project Profile
This Electric Generation facility agreed to make extensive changes to reduce sulfur dioxide emissions during the same period they were preparing to comply with the Utility MATS rule.
Like so many coal-burning power plants still in operation, this one has been modified heavily in recent years to reduce emissions. A facility consent decree required that SO2 emissions be curtailed by nearly half over the span of four years. One of the boilers was converted from burning coal to natural gas. The remaining two were altered to burn pulverized coal for more complete combustion. They also switched to low-sulfur sub-bituminous Powder River Basin (PRB) coal.
The impetus for this DAS implementation project was the Mercury Air Toxics standards (MATS) for Electric Utilities overlapping these other changes. They used the in-place DAS for about a year and a half after MATS went into effect, before switching to ESC|StackVision.
