SPRINGFIELD, Ga. (AP) -- The Georgia Environmental Protection Division has issued a new wastewater discharge permit to a company that was linked to a massive fish kill in the Ogeechee River.

Environmental Protection Division officials said Wednesday that the new permit limits King America's discharge of wastewater from its manufacturing plant to no more than 8 percent of the total river flow.

Officials say the company has agreed to pay $1.3 million to fund environmental improvement projects to benefit the river.

Authorities have said the company was discharging wastewater linked to a fire retardant processing line into the river without a permit in 2011. An estimated 39,000 fish were killed.

Officials say researchers from two universities will spend three years studying the river and its surrounding area, and will also install water quality monitors.
