The New York State Department of Environmental Conservation (DEC) is proposing a renewal and Department Initiated Modification (DIM) to the State Pollutant Discharge Elimination System (SPDES) Permit NY0268437, pursuant to 6 NYCRR Part 750-1.18, and 750-1.19, the Priority Ranking System known as New York State’s Environmental Benefit Permit Strategy (EBPS). This modification also includes requirements for the Source Water Protection program for the Mohawk Watershed.
The facility has a design flow of 0.1 MGD, and discharges treated wastewater via outfall 001 to a tributary of South Chuctanunda Creek, a class C water. Treatment consists manual bar screen, dual train sequencing batch reactors, effluent equalization tank, and rotating disc filters. Sludge is pumped to an aerobic digester and holding tank which is pumped and hauled offsite for disposal. Decant fluid from the digester and backwash water from the disc filters is sent to the head of the plant. The following changes to the permit are proposed: Updates were made to page 1 of the permit; Added daily maximum flow monitoring, and changed the sample frequency to daily; Added daily maximum mass load limits for BOD5 and TSS; Converted ammonia to (as N); Summer and winter limits have been converted to 1.2 mg/L and 1.9 mg/L, respectively; Mass loading limits for summer and winter; pH range has been reduced; Added new monitoring requirements for total dissolved solids and total copper; Added short term monitoring requirement for specific parameters as part of the Source Water Protection Program; Updated the monitoring locations section and added a note about future UV disinfection units that will be installed.
As a result of the EBPS full technical review, a new five-year term is proposed. The permit includes updated forms and the latest general conditions. Details of changes are specified in the draft permit and statement of basis which may be viewed and printed from the Department web site at: http://www.dec.ny.gov/permits/6054.html.
