Two new primary clarifiers of 130-ft. diameter each in the North Plant and
associated sludge pumping station; new odor control facility to serve the North
Plant; rehabilitation of the ten existing effluent filters including backwash
retrofits; rehabilitation of six existing primary clarifiers, and the primary influent

primary clarifiers and gravity thickeners, pursuant to the application received
February 23, 2004, and in conformity with the project plan, specifications, and

Environment and Natural Resources.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of

be required by this Division, such as the construction of additional or replacement wastewater
treatment or disposal facilities.
The DWQ Mooresville Regional Office, telephone number [phone], shall be
notified at least forty-eight (48) hours in advance of operation of the installed facilities so that an
on site inspection can be made. Such notification to the regional supervisor shall be made during

State holidays.
Upon completion of construction and prior to operation of this permitted facility, a
