existing wastewater treatment works and is permitted to discharge treated wastewater to White
Oak River, Class C waters of this State in the White Oak River Basin. The Town needs to
reduce and adequately treat high flows from excessive infiltration and inflow.The Town is
currently in noncompliance with permit conditions and limits for flow,Ammonia Nitrogen, Total
Residual Chlorine and Dissolved Oxygen. Compliance will require preparation of plans and
specifications for construction and operation of additional treatment works and an evaluation of
their collection system to reduce infiltration and inflow.

waters of this State named above, and the Town is within the jurisdiction of the Commission as
set forth in G.S. Chapter 143,Article 21.
(c) The Town desires to cause or allow the discharge of 0.01 MGD of additional wastewater to
the treatment works, and the discharge of such additional wastewater will not result in any
significant degradation to the quality of any waters. The nature of the additional flows is such
that the waste characteristics do not exceed those generally associated with domestic waste or are
pretreated to domestic strengths. Waste of greater than normal domestic strength will not be
approved for discharge. As part of the request for any additional wastewater other than the
10,000 gpd, the Town must demonstrate that there is no net increase in flow and the
discharge of such additional wastewater will not result in any significant degradation to the
quality of any waters. Provide the Washington Regional Office of the North Carolina Division

list each time flow is added to the system.

(d) The Town has secured a grant or has otherwise secured financing for planning, design,or
construction of a new or improved waste system and new disposal system which,once
constructed and operated,will be sufficient to adequately treat wastewater presently being
discharged,to such an extent that the Town will be able to comply with final effluent limits.
