Subject: Permit No. WQ0013263
Town of Boone
Distribution of Class A
Wastewater Residuals
Watauga County
In accordance with your request received on .lulu 7, 2000, we are forwarding herewith Permit No.
WQ0013263, dated September 27, 2000, to the Town of Boone for the continued operation of a facility and
program for the distribution of wastewater residuals. The product is a Class A wastewater residual that is generated
by a heat drying facility at the Town's Wastewater Treatment Plant site.
This permit is being modified to reduce the monitoring frequency for metals whose concentrations are
regulated by 40 CFR Part 503 from quarterly to annually in the residuals to be distributed. In addition, the
frequency with which a toxicity characteristics leaching procedure (TCLP) analysis must be performed on the
residuals to be distributed has been reduced from annually to once per permit cycle. Note that, according to 40
CFR Part 503, the monitoring frequency for pathogen densities as well as that to prove compliance with the
applicable "Process to Further Reduce Pathogens (PFRP)" and vector attraction reduction requirements cannot be
reduced from a quarterly basis.
This permit shall be effective from the date of issuance until February 28, 2002; shall void Permit No.
WQ0013263 issued December 23, 1997. and shall be subject to the conditions and limitations as specified therein.
Please take note of the following modifications that have been made to this permit:
♦ Condition I. L: A condition requiring the submission of the final engineer's certification to the Non -
Discharge Permitting Unit within 30 calendar days of this permit's issuance has been added, as
available records do not indicate that this certification has been received to date,
♦ Condition H. 7.: This condition has been amended to reflect the adoption of new rules by the Water
Pollution Control System Operators Certification Commission (WPCSOCC). The referenced
regulation is now 15A NCAC 8G .0202.
♦ Condition III, 3.: This condition has been amended to reflect the fact that the residuals only have to be
sampled and monitored for the metals whose concentrations are regulated by 40 CFR Part 503 on an
annual basis (i.e., reduced from quarterly). Other residual consituents not regulated by 40 CFR Part
503 must still be sampled and monitored on a quarterly basis.
♦ Condition III, 4.: A TCLP analysis now has to be performed on the residuals once per permit cycle
(i.e., reduced from annually). It is recommended that this test be performed in the same calendar year
in which the permit renewal application is due.

An Equal Opportunity Affirmative Action Employer 50% recycled/10% post -consumer paper
♦ Condition III. 5.: This condition has been amended to reflect the fact that the Division of Water
Quality will not entertain requests to reduce the monitoring frequency required to demonstrate
compliance with the required pathogen reduction and vector attraction requirements_
♦ Condition III. 6.: This condition has been amended to reflect the new mailing address to be used when
submitting all monitoring and reporting information.
♦ Condition III. 7.: The telephone number for the Winston-Salem Regional Office has been amended
with the correct area code in this condition.
As always, pay particular attention to the monitoring and reporting requirements contained in this permit.
Failure to establish an adequate system for collecting and maintaining the required operational information will
result in future compliance problems.
If any parts, requirements, 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
must be in the form of a written petition, conforming to Chapter 150B of North Carolina General Statutes, and filed
with the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714.
Unless such demands are made, this permit shall be final and binding.
If _you need additional information concerning this matter, plea contact Ms: Shannon. Mohr Thornburg at

systems constructed after December 31, 1983 is established at either (1) 250 feet from the waste
disposal area, or (2) 50 feet within the property boundary, whichever is closest to the waste disposal
area. An exceedance of Groundwater Quality Standards at or beyond the Compliance Boundary is
subject to immediate remediation action in addition to the penalty provisions applicable under North
Carolina General Statute §143-215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around disposal systems
