Dear Mr. Rowland:
A letter of request for Authorization to Construct was received October 6, 1998 by the Division
and final plans and specifications for the subject project have been reviewed and found to be

Specifically, authorization is granted for the following construction activities:
• Construction of a new concrete interceptor structure at the ash pond.
• Modification of the existing ash pond outlet.
• Installation of pipeline from the new interceptor structure at the ash pond to the existing concrete
outlet structure at the Cape Fear River ( Outfall 001).
• Installation of a pH control system on the ash slurry lines to the ash pond.
• Installation of a flow measuring system to continuously monitor the discharge volume from the
ash pond.
This Authorization to Construct is issued in accordance with Part III, Paragraph B of NPDES

subject the Permittee to an enforcement action by the Division of Water Quality in accordance with
North Carolina General Statute 143- 215.6A to 143- 215.6C.
The issuance of this Authorization to Construct does not preclude the Permittee from complying

agencies (local, state, and federal) which have jurisdiction. The sludge generated from these treatment
facilities must be disposed of in accordance with G.S. 143 -215.1 and in a manner approved by the North
