Attachment 5 - City of Walla Walla Wastewater Permit.pdf

This document is a Wastewater Discharge Permit issued by the City of Walla Walla to the Jonathan M. Wainwright Memorial Veterans Administration Medical Center for industrial wastewater discharge. The permit (No. P0006) authorizes the facility to discharge up to 70,000 gallons per day of domestic and non-categorical wastewater into the city's sewer system through two outfall points, with specific limitations on pollutant concentrations. The permit is effective from February 9, 2021, to February 8, 2026, and requires comprehensive monitoring and reporting of effluent parameters including metals, biochemical oxygen demand, total suspended solids, pH, and temperature.

Key compliance requirements include monthly and quarterly sampling of various pollutants, with 24-hour composite and grab samples to be collected and analyzed according to strict protocols. The permittee must submit detailed monitoring reports to the City of Walla Walla's Industrial Pretreatment Coordinator within 15 days of each reporting period, and maintain continuous compliance with local and federal pretreatment standards. Failure to meet permit conditions can result in enforcement actions, modifications to the permit, or potential permit termination, with specific provisions for addressing accidental discharges, slug discharge control, and other potential environmental compliance issues.
