Dear Mr. McIntosh:
Subject: Permit No. WQ0003254
Duke Power Company
Cliffside Steam Station
Ash Reuse Program
Rutherford County
In accordance with the amendment request from Mr. L. D. Evans, Scientist, Environmental
Protection - Waste Management, Generation Services Department, Duke Power Company, received
January 28, 1994, we are forwarding herewith Permit No. WQ0003254 as amended, dated April 29,
1993, to the Duke Power Company for the continued operation of an ash reuse program. Please be
advised, the total application of this material is limited to less than 300 acres of application area.
This permit is being amended as requested in the following areas:
a. Section 11(1)(a) - Structural fills were further defined by describing them as engineered fills
constructed of fly ash and bottom ash properly placed and compacted. However, the
Division does not agree on including areas of high intense public use such as parks, golf
courses, and ball fields as examples for using structural fills. If Duke Power Company
wishes to pursue these disposal alternatives, further documentation must be submitted to the
Division justifying them for using structural fills.
b. Section II(1)(b) - Flowable fills were exempted from all buffer requirements found in the
permit. Please be advised, only ponded ash, fly ash, and bottom ash used in flowable fills
will be exempted. If the Duke Power Company wishes to have any other ashes exempted
from the Solid Waste Requirements for Beneficial Use of Coal Combustion By -Products
(15A NCAC 13B .1701-1710) then approval must be requested and obtained from the
Division of Solid Waste.
c. Permit No- WQ0000452 was amended to indicate that the total application is limited to less
than 300 acres of application area.
d. Section II(6) has not been changed because the necessary information to show that ash can
meet the appropriate pipe bedding specifications has not been submitted from Duke Power
Company.
Please be advised, all future amendments to the subject pen -nit, no matter how minor, will require
a $400.00 permit processing fee.
