The meat and poultry industry could soon see major changes in requirements for dealing with wastewater in operations, including updated effluent limitation guidelines (ELGs) for the first time since 2004 and new requirements for nitrogen and phosphorus removal. The EPA’s proposed rule, which was released in December 2023, would apply to both direct and certain indirect dischargers, with stricter standards for nitrogen and, for the first time, phosphorus. While a final rule is anticipated by August 2025, the exact requirements and affected facilities may still change as the EPA considers multiple regulatory options and ongoing industry feedback.
Processors are strongly advised to proactively assess their current wastewater management systems and budget for potential capital improvements, as compliance could require significant upgrades, including new treatment technologies and operational changes. The EPA has indicated that flexibility will be built into the rule, allowing facilities to choose among different technologies and operational strategies for compliance. Facilities should also consider the potential for increased costs and longer compliance timelines, as well as the need for trained operators and possible changes in production processes.
