An Arkansas environmental regulatory agency denied a permit for a hog farm Monday because of concerns that pig waste might be contaminating the nearby Buffalo River. The Arkansas Department of Environmental Quality issued a final decision that C&H Hog Farm in Vendor can no longer operate. Its decision followed a period of public comment after the department initially denied the permit for the farm in September.The department first denied the farm's permit in January, but the farm appealed to the Arkansas Pollution Control and Ecology Commission, which sent the decision back to the department in August. The farm appealed that decision as well, and in October a judge ordered a stay on the department's decision to deny the permit in September.In its report, the department said it was denying the permit because of concerns that waste produced by the farm was contaminating the nearby Big Creek and Buffalo River. It tested two areas of each body of water close to the farm and found that all four "failed to meet water quality standards" under the department's regulations. Additionally, testing revealed higher levels of nitrates in the water and phosphorous in the soil.
