Subject: Issuance of NPDES Permit NCO086291
Beaver Hill WIT
Chowan County
The Division of Water Resources (the Division) hereby issues the attached NPDES permit for the subject facility.
This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the
Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated
October 15, 2007, or as subsequently amended.
The changes between this permit and the previous permit include the following:
• Flow limit has been removed.
• Total Iron and Total Lead is no longer required
• Added monthly turbidity monitoring.
• Effluent pH monitoring is twice per month.
• Total Residual Chloride (TRC) limit is 17 µg/L. The Division shall consider TRC effluent values reported
below 50 µg/L to be compliant with the pert. However, the Permittee shall continue to record and submit
all values reported by a North Carolina -certified test method (including field certified), even if these values
fall below 50 l g/L.
• Updated discharge stream segment to an unnamed tributary "Filbert Creels" to Edenton Bay [26-1] , currently
a Class C; NSW waterbody with Subbasin 03-01-04 of the Chowan River Basin.
Whole Effluent Toxicity test results submitted during the past three years have demonstrated that the Water
Treatment Plant's effluent is showing potential for causing aquatic toxicity in the receiving stream. As a result, the
Town of Edenton shall perform a Discharge Alternatives Evaluation as described in Section A. (4.) of this permit.
This evaluation is being requested to determine whether there are any economical and technologically feasible
alternatives available to the Town to comply with all NC Water Quality Standards. The permittee will be given
approximately one permit cycle to evaluate and document possible treatment/discharge alternatives to eliminate
aquatic toxicity The evaluation shall be submitted with the pennittee's next permit renewal application and will be
carefully reviewed by the Division and the results will be used in the development of a compliance schedule or
possible variance request for the Town.

NPDES Permit NC0086291
A. (4.) DISCHARGE ALTERNATIVES EVALUATION:
The Permittee shall assess potential alternatives to eliminate Whole Effluent Toxicity (WET) test failures.
This evaluation shall assess the feasibility of all the following alternatives.
1. Connect discharge to a WWTP: Determine whether the wastewater can be discharged to a wastewater
treatment plant. Approval or disapproval fiom the plant operator should be acquired.
2. Obtain a Non -discharge permit: Eliminate the surface water discharge by obtaining a non -discharge
permit for spray irrigation, infiltration, or subsurface disposal (on-site drainfield,
infiltration gallery, injection wells).
3. Install Wastewater Treatment: Install improved wastewater treatment to enable the facility effluent to
consistently pass the WET test. If this is not technically feasible or cost prohibitive,
please explain and provide estimated costs.
4. Use Alternative Water Treatment Source: Obtain drinldng water from another source (nearest
County, City, or Town or other wells) so the discharge or toxicity problem is
eliminated.
5. Use Alternative Water Treatment Method: Install alternative and/or innovative water treatment
methods or operational improvements that do not produce toxic wastewaters. For
example, install a recycle iron/manganese filtration system with no discharge or
combine discharge with WWTP or cooling water effluents.
6. Discharae to a Larger waterbody/Perform a dilution model: Relocate the facility's discharge to a
larger receiving waterbody to eliminate or reduce toxic impacts to the receiving
waterbody given the increased dilution. If applicable, perform a dilution model to
receive allowance for stream dilution in WET test.
7. Combination of Alternatives: Employ any combination of the alternatives listed above that would
result in eliminating or decreasing toxicity until a more feasible solution becomes
available.
The evaluation shall include a present value of costs analysis for all technologically feasible options as
outlined in the Division's "Engineering Alternatives Analysts Guidance Document." This Document can be
found at: http://portal.ncdenr.ora/web/wq/swp/ps/npdes/permits.
This evaluation is being requested to determine whether there are any economical and technologically
feasible alternatives available to the Permittee to address aquatic toxicity in the plant effluent. Based upon the
evaluation, please identify viable alternatives and present an implementation schedule and project timeline
for the preferred alternative. The Permittee shall submit the Discharge Alternatives Evaluation to the
Division along with the submission of their next permit renewal application (due 6 months prior to permit
expiration on June 1, 2017) to:
