Seneca Pure Waters recently had a meeting with the representatives from the D.E.C. Regional 8 office.  Although the New York Sewage Right to Know alert originally reported a spillage of over 34 million gallons, D.E.C. officials indicated that the volume was miscalculated, and subsequent alerts were corrected.  In reality, approximately 177,000 gallons of sewage spilled into the Keuka Outlet, and towards Seneca Lake.

The NYS Alerts also revealed the location of the incident: 135 Seneca Street, Penn Yan.  This property sits directly adjacent to The Birkett Mills.
