Ecology is proposing to modify the City of Mattawa’s State Waste Discharge Permit in accordance with the provisions of Chapter 90.48 Revised Code of Washington (RCW) and Chapter 173-216 Washington Administrative Code (WAC).
The City of Mattawa presently owns or operates a municipal treatment facility which is designed for an average monthly flow of 0.6 million gallons a day and uses a Biolac extended aeration activated sludge facility with ultraviolet disinfection and discharges via infiltration basins. Ecology is proposing to modify the City of Mattawa’s permit to change the maximum month design limit for TKN and add language to require online reporting of discharge monitoring reports.
The Department of Ecology (Ecology) is proposing to modify the permit to allow the modifications as requested above. Ecology is issuing a draft amended permit and fact sheet amendment and is only accepting comments on the modified portions.
The wastewater, following treatment, must meet the requirements of the Washington State Water Pollution Control Act and applicable regulations for a permit to be issued. A final determination will not be made until all timely comments received in response to this notice have been evaluated.
