Dear Mr. Vogt:
In accordance with your permit renewal and modification application package received on
January 9, 2006 as well as the additional information received on March 16, 2006, we are forwarding
herewith a renewed Permit No. WQ0011869, dated March 31, 2006, to the City of Wilmington for the
subject residuals processing facility and Class A EQ residuals product distribution program.
This pen -nit shall be effective from the date of issuance until February 28, 2011; shall void Permit
No. WQ0011869, issued on July 6, 2001; 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 City of WiImington's residuals
processing 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 City of
Wilmington to be conservative with its production estimates, so that the correct monitoring
frequency is selected for implementation. See Condition IH. 4. and Condition 1H. 5. for more
detail.

FOR THE
continued operation of a facility for the processing of residuals generated from the treatment of municipal
wastewater at the facilities listed in Condition 11. 3. and a program for the distribution of up to 7,000 dry
tons per year of a Class A EQ residuals product.
Both the facility and the program shall be operated such that no discharge of waste to surface
waters occurs, pursuant to the permit renewal and modification application package received on January
9, 2006 as well as the additional information received on March 16, 2006, and in conformity with the
project plan, specifications, and other supporting data subsequently filed and approved by the Department
of Environment and Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until February 28, 2011; shall void Permit
No. WQ0011869, issued on July 6, 2001; and shall be subject to the following specified conditions and

I. PERFORMANCE STANDARDS
The residuals processing facility and Class A EQ residuals product distribution program shall
be effectively maintained and operated as a non -discharge system to prevent the discharge of
any wastes to waters of the state resulting from the operation of this facility or program.
This permit shall become voidable in the event of failure of the residuals processing facility
or Class A EQ residuals product distribution program to adequately protect the assigned
water quality standards of the surface waters and groundwater.
The issuance of this permit shall not relieve the Permittee of the responsibility for damages to
surface water or groundwater resulting from the operation of this residuals processing facility
or Class A EQ residuals product distribution program.

4. In the event that the residuals processing facility or Class A EQ residuals product distribution
program is not operated satisfactorily, including the creation of nuisance conditions, the
Permittee shall take any immediate corrective actions as :may be required by the Division of
Water Quality (Division).
5. Diversion or bypassing of untreated residuals or leachate from the residual processing facility
shall be prohibited. All leachate shall be reused as a wetting agent for the processing of
residuals or disposed of through a Division -approved method.
6. When wastewater residuals are sold or given away, one of the Class A pathogen requirements
in 40 CFR Part 503.32(a) and one of vector attraction reduction requirements in 40 CFR Part
503.33 shall be met. Additionally, an evaluation shall be performed which demonstrates the
residuals' ability to comply with this requirement. Upon request, a copy of this evaluation,
including all test results and calculations, shall be submitted.
7. No Class A EQ residuals product that tests or is classified as a hazardous or toxic waste under
40 CFR Part 261 shall be sold or given away under the conditions of this permit.
U. OPERATION AND MAINTENANCE RE UIREMENTS

be properly operated and maintained at all times.
2. Upon classification of the residuals processing facility and Class A EQ residuals product
distribution program by the Water Pollution Control System Operators Certification
Commission (WPCSOCC), the Permittee shall employ a certified operator to be in
responsible charge (ORC) of the facility and program. The operator shall hold a certificate of
the type classification assigned to the facility and program by the WPCSOCC. The Permittee
shall also employ a certified back-up operator of the appropriate type to comply with the
conditions of 15A NCAC 8G .0202.
