Less than one month after state regulators made the controversial call to permit King America Finishing to continue dumping pollutants into the Ogeechee River — albeit, under “stringent” conditions — environmental activists are crying foul once more. Ogeechee Riverkeeper Inc. and GreenLaw, who fought to keep the textile manufacturer’s effluent from seeping into the river, have turned their focus toward the sky. The organizations are challenging a renewal of the Screven County plant’s air pollution permit, claiming the current draft permit lacks the requirements to effectively measure and limit large quantities of emissions.
