Darigold is considering adding a condensery to its existing systems in Sunnyside, which means an additional 100,000 gallons per day of wastewater would be discharged to the Port of Sunnyside's wastewater treatment plant.
Port of Sunnyside Engineer Bob Farrell yesterday told the port commissioners at a special meeting that the volume can be handled by the plant's wastewater treatment facility.
"If Darigold does move forward, it would initiate the process in October 2013," he said, adding the additional volume will remain under limits the port is permitted to treat.
"It's less than we are permitted to send to the sprayfields," said Farrell.
He said he has consulted with the Department of Ecology to ensure the capacity is acceptable under the port's wastewater treatment permit and the department has indicated there would not be any foreseeable issues.
Farrell said there has also been a noticeable reduction in the discharge volume, as well as mass loadings from Darigold in the past three years, providing a reasonable estimate of discharge for the future.
Taking that into account, Farrell believes the facility will continue to stay within its contracted volume levels with the Port of Sunnyside with the additional volume estimated for discharge predicted from the condensery.
He said there may need to be an adjustment to the contract for storage periods.
Farrell told the commissioners the Port of Sunnyside wastewater facility will be able to run efficiently and he sees no issues with the additional capacity to be discharged if Darigold moves forward with its plans.
