A fast track application for Authorization to Construct dechlorination facilities was received on

fast track application received on July 1, 2008, and in conformity with the
Minimum Design Criteria for Dechlorination Facilities.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of
NPDES Permit No. NCO083101 issued December 1, 2007, and shall be subject to revocation

limitations specified in Permit No. NCO083101.
In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those as may
