Transmitted herewith are the completed/signed originals and two copies each of the subject
NPDES permit application and cover letter. Since this facility does not generate any sludge, no
sludge management plan is necessary. There have been no modifications since the last permit
was issued; however an authorization to construct (ATC) application will be forthcoming for the
construction of de -chlorination facilities approved in the current NPDES permit.
It is my understanding that no filing fee is required for this renewal.
If you have questions regarding this application, please do not hesitate to contact me.
