The ruling states that hog farm ordinances set in place by Chatham County officials overstepped boundaries, preempting the ordinances in favor of state laws.
Frank Sheffield, the attorney who represented those opposing the ordinances, said although the ruling only affects Chatham County, it will set a precedent for other N.C. counties.
"The significance is statewide because the courts said counties do not have the authority to regulate swine operations," he said. "(Other counties') ordinances may be invalid as well."
Sheffield said Chatham County adopted regulations that were stricter than those set by the state, especially in areas concerning the location of the hog farms.
"State law has a setback of 1,500 feet from the nearest occupied residence and 2,500 feet from the nearest church or school," he said. "Chatham County had a setback of 5500 feet."
Sheffield said the required distance made it virtually impossible for farmers to establish new hog farms in the county. "The hog farm would have to be located over a mile to the nearest residence in all directions."
But some environmental advocates believe counties should be able to regulate hog farms on their own.
Dan Whittle, an attorney for Environmental Defense, an environmental advocacy group, said counties deserve the same rights states are given in setting environmental standards.
"The federal government adopts environmental laws but allows states to adopt even stricter ones," Whittle said. "One environmental law doesn't necessarily fit everybody."
