A Class II Inspection was conducted in October 1992 at the Yakima Regional Wastewater Treatment Plant. The Yakima facility provides secondary treatment of domestic wastewater for the city of Yakima and adjoining urban areas. It also applies untreated wastewater from several food processing plants to sprayfields located along the Yakima River. Inspection data found that Yakima was providing adequate treatment for most pollutants limited by the NPDES permit. (Also see abstract below) | |||

| Abstract | Long Description |
A Class II Inspection was conducted in October 1992 at the Yakima Regional Wastewater Treatment Plant. The Yakima facility provides secondary treatment of domestic wastewater for the city of Yakima and adjoining urban areas. It also applies untreated wastewater from several food processing plants to sprayfields located along the Yakima River. Inspection data found that Yakima was providing adequate treatment for most pollutants limited by the NPDES permit. Total ammonia and fecal coliform effluent concentrations were of some concern. Influent loading for BOD5 exceeded monthly average design criteria included in the NPDES permit. Influent flow exceeded 85% of design criteria. Revising plant criteria to reflect recent plant upgrades or submitting a plan and schedule to the Department of Ecology for the maintenance of adequate treatment is recommended. |
