# Secrecy Around North Carolina's Industrial Poultry Operations Ends With EPA Complaint Maps
North Carolina's industrial poultry industry has operated largely out of public view for decades. That opacity ended when the U.S. Environmental Protection Agency received a complaint days before Christmas 2023 describing overwhelming odor so severe it was making residents physically ill. The complaint, filed through the EPA's National Response Center, targeted operations the state had kept hidden from public scrutiny.
State records now reveal the locations of North Carolina's concentrated animal feeding operations, or CAFOs, through the formal complaint process. This disclosure marks a shift toward transparency in an industry long shielded by agricultural exemptions and limited regulatory oversight.
North Carolina ranks second nationally in swine production and maintains one of the nation's largest poultry industries. Industrial facilities confine tens of thousands of birds in single operations, generating waste management challenges that affect nearby communities. Ammonia emissions from poultry litter, hydrogen sulfide, and volatile organic compounds create persistent odor problems documented in EPA complaints and health complaints filed with local authorities.
The complaint from late December 2023 represents a common pattern. Residents in agricultural regions report similar issues regularly. These odor events correlate with documented health effects. Exposure to air pollution from concentrated animal agriculture associates with respiratory problems, headaches, and nausea in nearby populations, according to research from environmental health institutions.
North Carolina's poultry operations largely escape detailed public mapping despite their scale. Unlike swine CAFOs, which face stricter permitting requirements under state law, poultry facilities operate with less regulatory visibility. The state Department of Environmental Quality maintains records, but accessing location data requires formal requests or complaints that trigger disclosure.
The EPA's National Response Center logs complaints about environmental violations, including air quality issues from agricultural sources. Each documented complaint generates a record that eventually becomes public through EPA databases and state environmental agency files. The Christmas week complaint that mentions specific odor impacts provides a window into problems residents face seasonally.
North Carolina's poultry industry generates substantial economic output. The state produces over 700 million broilers annually and employs thousands in processing and production. However, the concentration of facilities in specific counties, particularly in the eastern part of the state, creates localized environmental burdens. Duplin and Sampson counties alone host multiple large operations.
Waste management from poultry operations presents ongoing challenges. Litter accumulation requires storage or land application, both sources of ammonia volatilization. Improperly managed waste spreads bacteria and pollutants into waterways. Ammonia emissions contribute to nitrogen deposition in fragile ecosystems downwind of facilities.
The EPA complaint process represents one mechanism for environmental accountability when state oversight proves insufficient. Complaints trigger investigations and can result in enforcement actions. However, reliance on complaints shifts burden to affected residents to identify problems and navigate federal reporting systems.
Transparency enables communities to assess environmental risks and hold operators accountable. Publishing CAFO locations and emissions data would provide residents, researchers, and policymakers with baseline information to evaluate environmental compliance and health impacts. Several states have implemented online registries mapping concentrated animal operations.
North Carolina faces pressure to expand public access to CAFO location data and emissions monitoring. Environmental organizations have pushed for stronger oversight of poultry facilities comparable to swine regulations. State legislators have proposed bills requiring more detailed permitting and emissions tracking, though industry opposition remains strong.
