In consideration of the current Hammersley Inlet shellfish growing area closure, due to the presence of Norovirus, the City of Shelton is taking extra precautions to ensure that the Wastewater Treatment Plant continues to exceed Washington State Department of Ecology testing standards. 
The City is sensitive to the nearby shellfish industry and the surrounding environment, and has consistently conducted additional discharge testing beyond the minimum regulatory requirements. Moving forward, facility operators are committed to maintaining this elevated standard of performance.
In response to the Norovirus outbreak, the Washington State Department of Health did an onsite evaluation of the plant on April 12, 2017, which included a review of the City’s discharge monitoring reports. It was determined that the facility has met all National Pollutant Discharge Elimination System (NPDES) discharge permit conditions throughout the period of concern, with no reported collection system overflows or main breaks.
The City will continue to work closely with both the Washington State Department of Ecology and the Department of Health on ruling out the City’s Wastewater Treatment Plant as the source of any pollution containing Norovirus.
