Wapato fined for excess pollution discharges
According to an agreement announced Thursday, the plant exceeded allowed levels of ammonia in its discharge permit more than 430 times between 2006 and 2010.
The EPA said the facility also discharged without a permit between June 2010 and September 2011.
The city's wastewater treatment plant provides secondary treatment before water is discharged to the Yakima River.
The EPA's Kimberly Ogle said Wapato is working with the EPA to come into compliance.
