a. Any process unit failure, due to known or unknown reasons, that render the facility incapable of
adequate wastewater transport such as mechanical or electrical failures of pumps, line
blockage or breakage, etc.
b. Any failure of a pumping station or sewer line resulting in a by-pass directly to receiving waters
without treatment of all or any portion of the influent to such station or facility.
Voice mail messages or faxed information is permissible but this shall not be considered as the initial
verbal report. Overflows and spills occurring outside normal business hours may also be reported to
the Division of Emergency Management at telephone number [phone] or [phone].
Persons reporting any of the above occurrences shall file a spill report by completing Part I of Form
CS-SSO (or the most current Division approved form), within five days following first knowledge of the
occurrence. This report shall outline the actions taken or proposed to ensure that the problem does
not recur. Per Condition 1(2), Part II of Form CS-SSO (or the most current Division approved form) can
also be completed to show that the SSO was beyond control.
16. The pressure sewer lines permitted herein shall be designated "high priority" until such time that the
contributing flow provides a velocity exceeding 2 feet per second. High priority lines must be
inspected once every six months and cleaned as necessary.
17. A variance is granted for the use of SDR 13.5 PVC in lieu of DIP in areas where the separation
between the force main and individual wells is less than 100 feet. In no instance shall the separation
be less than 25 feet. This line shall be tested to water main standards with no leakage.
