Revised WDRs for Setton Pistachio and Porterville Citrus Terra Bella Processing Facilities

The Revised Waste Discharge Requirements regulate wastewater discharges from the Setton Pistachio and Porterville Citrus processing facilities in Terra Bella, California, establishing strict limits to manage environmental impacts. The authorization permits a maximum daily discharge of 3.0 million gallons of pistachio processing wastewater and a total annual limit of 80 million gallons, while allowing up to 0.08 million gallons per day for citrus processing wastewater. These limits are designed to ensure compliance with water quality standards and minimize contamination of local water resources. The requirements apply specifically to operations at the Terra Bella Processing Facilities and are enforced by the Regional Water Quality Control Board, Region 5 – Fresno, under the authority of the State of California. The discharge permits are overseen by Alexander Mushegan, Supervising Water Resource Control Engineer at the Regional Water Quality Control Board, who serves as the primary point of contact for regulatory compliance and inquiries. Fernando Rios, Manager at Setton Farms, is listed as a secondary contact, representing the facilities’ operational interests. The regulatory framework was issued effective June 11, 2026, and applies to operations within the 93270 zip code area in California. The updated WDRs reflect a formalized commitment to sustainable industrial practices and water resource protection in the region.
