Charlotte -Mecklenburg Utilities
Mecklenburg County
FOR THE
operation of a wastewater residuals facility for the distribution of Exceptional Quality Class A residuals

with no discharge of wastes to the surface waters, pursuant to the application received on July 7, 1998 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 July 31, 2004, shall void Permit No.
WQ0006497 issued January 25, 1995, and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
1. The distribution of Exceptional Quality CIass A residuals program shall be effectively maintained
and operated as a non -discharge system to prevent the discharge of any wastes resulting from the
operation of this program.
2. This permit shall become voidable in the event of failure of the residuals program to adequately
protect the assigned water quality standards of the surface waters and groundwaters.
3. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to
surface or groundwaters resulting from the operation of this program.
4. In the event that the residuals 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 the untreated residuals or leachate from the residual treatment facilities
is prohibited.
6. All leachate must be reused as a wetting agent for the processing of residuals or routed to the head
of the treatment plant.

II.
7. When wastewater residuals are sold or given away, one of the Exceptional Quality Class A
pathogen requirements in 40 CFR Part 503.32(a) and one of vector attraction reduction
requirements in 40 CFR Part 503.33(b)(1) — (b)(8) must be met. Additionally, an evaluation must
be performed which demonstrates the residuals ability to comply with this requirement. Upon
request, a copy of this evaluation must be submitted including all test results and calculations.

following the occurrence or first knowledge of the occurrence of any of the following:
a: Any occurrence with the distribution program which results in the land application of
significant amounts of wastes which are abnormal in quantity or characteristic.
b. Any failure of the distribution program resulting in a release of material to receiving waters_
c. Any time that self -monitoring information indicates that the facility has gone out of
compliance with the conditions and limitations of this permit or the parameters on which the
system was designed.

actions taken or proposed to be taken to ensure that the problem does not recur.

IV. GROUNDWATER REQUIREMENTS
I. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in 15A
NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary is for the
disposal -system 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 General Statute 143-215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the disposal
systems midway between the Compliance Boundary and the perimeter of the waste disposal area.
Any exceedance of standards at the Review Boundary shall require remediation action on the part
of the permittee.
2. Any groundwater quality monitoring, as deemed necessary by the Division, shall be provided.
V. INSPECTIONS
L The Permittee or his designee shall inspect the residuals storage, transport, and treatment facilities
to prevent malfunctions and deterioration, operator errors and discharges which may cause or lead
to the release of wastes to the environment, a threat to human health, or a nuisance. The Permittee
shall maintain an inspection log or summary including at least the date and time of inspection,
observations made, and any maintenance, repairs, or corrective actions taken by the Permittee.
This log of inspections shall be maintained by the Permittee for a period of five years from the
date of the inspection and shall be made available to the Division or other permitting authority,
upon request.
2. Any duly authorized officer, employee, or representative of the Division may, upon presentation
of credentials, enter and inspect any property, premises or place on or related to the treatment site
or facility at any reasonable time for the purpose of determining compliance with this permit; may
inspect or copy any records that must be kept under the terms and conditions of this permit; and
may obtain samples of groundwater, surface water, or leachate_
