Project is Located:

WASHINGTON, DUTCHESS COUNTY

Project Description:

The Department has prepared a draft permit and has made a tentative determination, subject to public comment or other information, to approve and set a new permit term for an increased existing discharge to a proposed discharge of 0.37 million gallons per day (MGD) of treated sanitary wastewater to "East Branch of Wappingers Creek," H-101-21, a class C, standard C(T) stream from a preliminary, primary, secondary, tertiary, and disinfection treatment plant at the applicant's facility address located at 39 North Avenue in the Village of Millbrook. The facility is a publicly owned treatment works that receives flow from domestic users, with effluent consisting of treated sanitary water for the Village of Millbrook. The applicant plans to modify the existing SPDES permit, as the permit limit changed from 12-month rolling average to monthly average. While no additional flow is intended to be accepted by the plant, the change in calculation method necessitates a change from an average daily design flow of 0.25 MGD to 0.37 MGD.
