February 26, 1996, we are forwarding herewith Permit No. WQ0000563 as amended, dated June 21,
1996, 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, to incorporate the following option into the permit:
Section I1(1)(h) - Bottom ash may be utilized for snow and ice control at a rate not to exceed
700 pounds per mile lane. Since this activity is considered de-minimus with
respect to environmental impact, performance standards 13 and 14 shall not
apply to this alternative.
Please be advised, the Division of Environmental Management is presently negotiating with the
Division of Solid Waste concerning the regulatory authority over the ash reuse program. Sometime in
the near future, the Duke Power Company will be notified whether or not they must apply for a permit
under that Division. If a permit must be obtained from Solid Waste, the subject permits issued by the

Permit No. WQ0000563 issued September 8, 1994, and shall be subject to the conditions and limitations
as specified therein. Please pay particular attention to the monitoring requirements in this permit.
Failure to establish an adequate system for collecting and maintaining the required operational
information will result in future compliance problems.

right to request an adjudicatory hearing upon written request within 30 days following receipt of this
permit. This request must be in the form of a written petition, conforming to Chapter 150B of North
