Dear Mr. Hudson:
Per a telephone request received on September 8, 2003 from Mr. Mark D. Cathey, P.E. of McGiIl
Associates, P.A. on the City of Statesville's behalf, we are forwarding herewith a corrected Page 1 of Permit No.
W Q0001759.
The following correction has been made to the permit:
1. The description of the rehabilitated final cover system for Area No. 3, Area No. 5, and Area No. 7 of
the surface disposal unit did not accurately reflect the approved closure plan and post -closure care plan
included as Attachment A of the permit. Specifically, the entire rehabilitated final cover system is
planned to be two feet in depth, consisting of a minimum of 1.5 feet of compacted soil with a
minimum hydraulic conductivity of 1.0 x 10'5 centimeters per second overlain by six inches of soil for
the purpose of erosion control and vegetation establishment and maintenance. The description
previously stated that the entire rehabilitated final cover system was to be 2.5 feet in depth, two feet of
compacted soil followed by the six-inch soil erosion/vegetation layer.
Please replace Page 1 with this corrected Page 1 into Permit No. WQ0001759, issued on March 21,
2003. The Division apologizes for any confusion that this error may have caused.
If you need any additional information concerning this matter, please contact Ms. Shannon Mohr
Thornburg via telephone at [phone], extension 353, or through e-mail at sha [e-mail].
