Dear Ms. Mendenhall:
In accordance with on -going discussions between Mr. Robert H. Forbes, Jr., P.E. of CH2M-Hill,
and the Division, we are forwarding herewith Permit No. WQ0006497 as amended, dated January 25,
1995, to the Charlotte -Mecklenburg Utility Department for the construction and operation of a dual train 40
dry ton per day aerated static pile compost and alkaline stabilization wastewater residuals facility for the
distribution of Class A residuals. The permit is being amended to clarify which analysis need to be run on
the raw, unprocessed residuals and the finished product.
This permit shall be effective from the date of issuance until December 31, 1998, shall void Permit
No. WQ0006497 issued October 14, 1994, and shall be subject to the conditions and limitations as
specified therein. Please 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 thirty (30) days following receipt of
this permit. This request must be in the form of a written petition, conforming to Chapter 150B of North

adequately protect the assigned water quality standards of the surface waters and
groundwaters.
5. 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.
6. 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.
7. Diversion or bypassing of the untreated residuals, leachate, or stormwater runoff from the
residual treatment facilities is prohibited.
8. All leachate must be reused as a wetting agent for the processing of residuals or routed to
the head of the treatment plant.
9. All liquid wastes from the odor control scrubbers must be collected and routed to the head
of the treatment plant.
10. 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
