Dear Ms. Mendenhall:
In accordance with your permit renewal and modification application package received on
November 9, 2004, we are forwarding herewith a renewed Permit No. WQ00006497, dated June 15,
2006, to Charlotte -Mecklenburg Utilities for the subject residuals processing facility and Class A EQ
residuals product distribution program.
This permit shall be effective from the date of issuance until May 31, 2011; shall void Permit No,
WQ00006497, issued on August 25, 1999, 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 Charlotte -Mecklenburg Utilities
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 Charlotte -
Mecklenburg Utilities to be conservative with its production estimates, so that the correct
monitoring frequency is selected for implementation. See Condition III. 4. and Condition III.
5. for more detail.
