Attorneys representing the Ogeechee Riverkeeper Association filed a petition for mandamus Tuesday in Screven County Superior Court, seeking to force the Georgia Environmental Protection Division to halt a textile company’s discharge of wastewater into the Ogeechee River.A petition for mandamus asks the court to require a public official to perform a nondiscretionary duty.King America Finishing, located along the river near Dover, was found to have been releasing waste without a permit after an EPD investigation in May 2011, following a massive fish kill in which about 38,000 fish died downriver of the plant.EPD officials learned the plant had violated several mandates and had not renewed its permit for several years before the investigation. A consent order to fund $1 million in river improvements was issued, but was appealed. Earlier this year, EPD withdrew its consent order and proposed a new order.
