| Short Description |
An announced Class II wastewater inspection of the Basic American Foods (BAF) spray irrigation facility was conducted on April 27-29, 1998. The inspection was conducted in conjunction with a Class II groundwater inspection of the BAF facility and in conjunction with Class II wastewater and groundwater inspections of the nearby Moses Lake (Dunes) wastewater treatment plant. The Class II wastewater inspection included sampling of the effluent stream at BAF. Groundwater monitoring results appear in separate study reports. (Also see abstract below) | |||

| Abstract | Long Description |
An announced Class II wastewater inspection of the Basic American Foods (BAF) spray irrigation facility was conducted on April 27-29, 1998. The inspection was conducted in conjunction with a Class II groundwater inspection of the BAF facility and in conjunction with Class II wastewater and groundwater inspections of the nearby Moses Lake (Dunes) wastewater treatment plant. The Class II wastewater inspection included sampling of the effluent stream at BAF. Groundwater monitoring results appear in separate study reports. The 1.52 MGD flow rate measured during the inspection is within the 1.66 MGD permitted monthly average flow rate. The other permit limitation is the stipulation that the system must be operated by the permittee so as to protect the existing and future beneficial uses of the groundwater. The groundwater inspection conducted concurrently with this wastewater inspection found that BAF wastewater disposal practices have degraded groundwater quality in the vicinity of its spray fields. An agronomic analysis shows that agronomic rates for nitrogen uptake were exceeded before BAF more than doubled the land area irrigated by its wastewater since 1996. BAF irrigation on increased acreage is within agronomic rates calculated on an annual basis for potatoes and corn but not for wheat. This assumes that any additional fertilizer used is not over-applied. BAF irrigates continuously all year, as allowed by the permit. Whether this causes an exceedance of agronomic rates needs to be determined. |
