Dear Mr. Young:
In accordance with your permit renewal application package received on July 12, 2002 as well as
the additional information received on July 24, 2002 and August 23, 2002, we are forwarding herewith a
renewed Permit No. WQ0013263, dated October 6, 2005, to the Town of Boone for the subject residuals
drying facility and Class A EQ residuals product distribution program.
This permit shall be effective from the date of issuance until September 30, 2010; shall void
Permit No. WQ0013263, issued on September 27, 2000 and corrected on October 27, 2000; and shall be
subject to the conditions and limitations as specified therein. Make note of this permit's expiration date
and the fact that a permit renewal application is due to the Division of Water Quality (Division) no later
than six months prior to that date (i.e., see Condition VI. 7.), as the Division does not send reminders to
apply for permit renewal.
This permit has been issued to approve the operation of the Town of Boone's residuals drying
facility and the Class A EQ residuals product for another five-year cycle. As always, remember to take
the time to review this permit thoroughly, as some of the conditions contained therein may have been
added, changed!, or deleted since the last issuance. Pay particular attention to the monitoring
requirements in this permit. Please be aware that failure to establish an adequate system for collecting,
maintaining, and submitting the required operational information will result in future compliance
problems. Of special interest to you may be the following;
♦ All monitoring required by this permit, with the exception of process/operational data that
must be maintained to prove compliance with the pathogen reduction and vector attraction
reduction requirements, must be completed on the Class A EQ residuals product that is
intended for distribution.

♦ The Division has amended the frequency with which the Class A EQ residual product must
be monitored so that it is more commiserate with 40 CFR Part 503. Specifically, the
frequency with which monitoring must now be performed is based entirely on the amount of
product that is distributed for application to the land. The Division urges the Town of Boone
to be conservative with its production estimates, so that the correct monitoring frequency is
selected for implementation. See Condition Ill. 4. and Condition III. 5. for more detail. Note
that this change in the Monitoring and Resorting Requirements section of the permit
effectively reverts the Town of Boone's previous request to reduce its monitoring frequena
from quarterly to annually that was a roved b with the previous issuance of this ermit.
This is because the Division has recently received guidance from Region IV of the United
States Environmental Protection Agency (EPA) that, since the State of North Carolina has not
received delegation of the 40 CFR Part 503 program, it is not the "permitting authority"
referred to by those rules. Therefore, even though the Division can approve a monitoring
frequency reduction under the this permit, the Town of Boone would still have to perform the
monitoring at the frequency required in 40 CFR Part 503 to meet the federal requirements.
As such, it is now the Division's policy to reduce monitoring frequency only for Permittees
who have previously received written acknowledgment of the same from Region IV of EPA.
♦ The Division suggests that the Town of Boone develop a monitoring program to ensure that
the Class A EQ residuals product does not exhibit signs of pathogen regrowth following
significant storage time and immediately prior to distribution for application to the land.
If any parts, requirements, and/or limitations contained in this permit are unacceptable, you have
the right to request an adjudicatory hearing upon written request within 30 days following receipt of this
permit. This request shall be in the from of a written petition, conforming to Chapter 150B of the North
Carolina General Statutes and filed with the Office of Administrative Hearings at 6714 Mail Service
Center, Raleigh, North Carolina 27699-6714. Unless such demands are made, this permit shall be final
and binding.
If you need any additional information concerning this matter, please contact Ms. Shannon Mohr
Thornburg by telephone at [phone], or via e-mail at shannon.thornburg@'Ycmail.net.
