Subject: Demonstration of Future Wastewater Treatment Capacities
NPDES Permit NC0043176

DearMr. Uskiewicz:
15A-NCAC 2H .0223 "Demonstration of Future Wastewater Treatment Capacities," was adopted
by the Environmental Management Commission to, ensure that wastewater treatment systems
owned or operated by municipalities, counties, sanitary districts or public utilities do not exceed
their hydraulic treatment capacities. This Rule specifies that no permits for sewer line extensions
will be issued by the Division of Water Quality to facilities exceeding 80% of their hydraulic
treatment capacity unless specific evaluations of future wastewater treatment needs had been
completed. Facilities exceeding 90% of their hydraulic treatment capacity must submit plans and
specifications and obtain all permits needed for expansion of the wastewater treatment system
before permits for sewer line extensions may be issued.
A review of your self monitoring reports has indicated flow at the subject facility exceeded the
90% threshold for calendar year 2003. The average flow calculated for this period was 3.022
MGD, and represented 100.7% of the current treatment capacity. Therefore, we will be unable
to approve any further sewer line extensions for this facility until such time as you have
complied with the requirements contained in the Rule.
In order to attain compliance with the Rule, you must obtain all permits needed for expansion of
the wastewater treatment system and, if construction is needed, submit approvable final plans
and specifications for expansion of the wastewater treatment system, including a construction
schedule. If expansion is not proposed or is proposed for a later date, a detailed justification
must be made and approved by the Director based on past growth records and future growth
projections and as appropriate, shall include conservation plans or other specific measures to
achieve waste flow reductions.

Per the terms of NCAC 2H. 0223 (3), the Director may, on a case by case basis, allow permits to
be issued to facilities exceeding the 80 percent loading rate if: 1) the additional flow will not
cause the facility to exceed its permitted hydraulic capacity, 2) the facility is in compliance with
all other permit limitations and requirements and 3) it is demonstrated that adequate progress is
being 'made in developing the required engineering evaluations or plans and specifications. If
you wish to ask for a waiver of the moratorium per this provision of the rule, please send
information in support of your request to the address listed above.
As always, the actual plans and specifications for expansion should be submitted to the NPDES
Unit of the Water Quality Section.
We look forward to working with you on development of plans to meet your future wastewater
treatment needs. If you have any questions regarding this matter, please contact the Water.
Quality Section staff of our Fayetteville Regional Office at [phone], or Vanessa Manuel
of the Point Source Compliance/Enforcement Unit, at [phone], extension 532.
