The A. B. Brown Generating Station is a four-unit, 700-MW power generating facility, located on the northern bank of Ohio river, 8 miles east of Mount Vernon, Indiana and 5 miles southwest of Evansville, Indiana just west of the Posey-Vanderburgh County Line.[1] Each of the two coal-fired units has a name-plate capacity of 265.2 MW. Bituminous coal is used as a primary fuel type, which can be substituted for natural gas.[2] There are also two gas turbine units, 88.2 MWe of nameplate capacity each. The facility is owned by Vectren Corporation,[3] formerly Southern Indiana Gas and Electric Company.
[edit] Environmental impact
[edit] Ash ponds
The A. B. Brown Station ash management impoundment was formed by building a dam to block off the outlet of a natural ravine about 0.5 miles (0.8 km) from the Ohio river. The ash pond consists of two dams. The Lower dam (built in 1978) has been classified by the Indiana DNR as a Significan Hazard (State ID#65-7, permit #D-4405, rev 1). The Upper dam (constructed in two phases in 2002 and 2007) was not classified, but has a permit #FW-21909. Liquid wastes being sluiced into the pond include fly ash, bottom ash, boiler slag, FGD belt filter wash down and water sump wastes, pyrites, material removed from the coal pile run-off pond, plant floor drain wash downs, boiler chemical leaning wastes, reverse osmosis system rejects, and rainfall/runoff from the surrounding area. According to Vectren, no discernable amount of material has been removed from the pond sincee it first began operation in 1978.[4]
