Effluent Guidelines

Meat and Poultry Products Effluent Guidelines

EPA initially promulgated the Meat and Poultry Products (MPP) Effluent Guidelines and Standards in 1974, and amended the regulation in 2004. The regulation (40 CFR Part 432) covers wastewater directly discharged by slaughterhouses, further processors, independent renderers and poultry processors. The requirements are incorporated into NPDES permits.
