Dear Mr. Forest:
A letter of request for an Authorization to Construct was received December 23, 1992 by the
Division and final plans and specifications for the Administrative Building have been reviewed and found
to be satisfactory. Authorization is hereby granted for the construction and operation of approximately 400
linear feet of 8 inch DIP inch gravity sewer to serve the Irwin Creek Administrative Building into the
headworks of the Irwin Creek Wastewater Treatment System, pursuant to the application received
December 23, 1992, and in conformity with the project plan, specifications, and other supporting data
subsequently filed and approved by the Department of Environment, Health and Natural Resources and
considered a part of this permit. In accordance with 15A NCAC 2H .0204, construction of the
Administrative Building is not required to be covered under the Division's review of the Authorization to
Construct. This approval is for the sewer connection of the Administrative Building only.
The plans and specifications for the Trucked Wastewater Receiving Station have been reviewed
and found to be satisfactory. Authorization is hereby granted for the construction and operation of the
Trucked Wastewater Receiving station consisting of 115 linear feet of 24 inch DIP gravity line for
connection to the headworks connection being prepared by Gannett Fleming Engineers and Planners
(Authorization ACA024945) and all associated valves, piping and appurtenances needed for the
completion and operation of the Trucked Wastewater Receiving Station. This authorization is for the
collection system and discharge into the headworks of Irwin Creek WWTP. Connection to the headworks
cannot be completed until approval, construction and inspection of the headworks upgrade (contained in
ACA024945). Notification of connection must be made to the Mooresville Regional Office before
