The Illinois Environmental Protection Agency (IEPA) is taking public comment until Aug. 11 on its tentative determination to issue a NPDES water permit related to dry sorbent injection systems to be installed at the coal-fired Kincaid power plant.
Kincaid Generation LLC operates two cyclone wet bottom boilers to supply steam to two generating units rated at 1,180 MW combined. The station, located in Christian County, withdraws water from a 1,377 acre cooling pond (Lake Sangchris) for condenser cooling and house service water.
“The subject facility has applied for a renewed NPDES permit which includes a new waste stream that necessitates an antidegradation assessment,” said an IEPA public notice. “The facility is planning on installing a dry sorbent injection system to minimize atmospheric discharges of sulfur dioxide and acid gasses. The dry sorbent product (sodium bicarbonate) to be injected into the boiler’s flue gas stream must first be milled to a fine powder on-site.”
The following permit modifications are proposed:
- Proposed discharge of 400 gallons per day of wash water from the dry sorbent product (sodium bicarbonate) handling/milling area tributary to wastewater outfall B01.
- Proposed discharge 1 gallon per day of condensate from the continuous mercury monitoring system tributary to outfall B01.
Dominion Resources (NYSE: D) sold the Kincaid plant last year to Energy Capital Partners II LLC. Dominion announced in 2012 that it had awarded the KBR Power & Industrial Group a contract to provide engineering, procurement, and construction (EPC) services for a dry sorbent injection system to reduce SO2 emissions at Kincaid.
