Special Condition(s): Sludge disposal and Reliability (Standby power)
Permits & Engineering Comments:
This is a permit renewal for an existing class II facility. Flow conditions for this facility are tidal.
This facility was previously issued for a flow of 0.500 MGD with an A to C for only 0.100 MGD. Permits
and Engineering is recommending that this permit be issued with existing secondary limits at 0.100
MGD. Given the low levels of dissolved oxygen in this area, any "unbuilt" flow will be given limits of
technology for oxygen -consuming waste. In this instance, the 0.5 MGD phase of the project will be
limited at 5 mg/1 (BOD-Summer) and 2.0 mg/1 (NH3-Summer). Also, a TRC limit of 28.0 mg/1 will be
given at this flow. For the design flow of 0.100 MGD, an ammonia limit of 20.0 mg/1 has been
recommended by the regional office. This plant has been in compliance with limitations with the
exception of two TSS violations within the past twenty four months. The ammonia toxicity is of some
concern here because they were in the range of 1.0 mg/1 to 30.0 mg/1 within the past twenty four months.
According to the region, sludge disposal should remain as a condition along with the reliability
condition requiring standby power.

Permit Summary
NC0065480
This is a permit renewal for an existing class II facility. Flow conditions for this
facility is tidal. This facility was previously issued for a flow of 0.500 MGD
with an A to C for only 0.100 MGD. Permits and Engineering is recommending
that this permit be issued with existing secondary limits as an expansion from
0.100 MGD to 0.500 MGD. Both will have the recommended ammonia limit of
20.0 mg/I by the region. This plant has been in compliance with limitations with
the exception of two TSS violations within the past twenty four months. The
ammonia toxicity is of some concern here because they were in the range of 1.0
mg/1 to 30.0 mg/1 within the past twenty four months. Talking with the region
sludge disposal will be left in as a condition along with the reliability condition
requiring standby power.

5. Other Special Items: There is no standby power supply
available. It is recommended a permit condition be included
to require the Permittee to satisfy plant reliability criteria
under 2H .0124 (2) .
PART IV - EVALUATION AND RECOMMENDATIONS
Average flows at Beau Rivage are 0.014 MGD because of
construction of approximately 150 out of a proposed 1200
units. It is due to the proposed number of units to be built
that the current limit of 0.5 MGD is recommended be kept for
the new permit. A letter justifying need for the 0.5 MGD has
been requested from the Permittee.
The plant is generally is good mechanical condition and has
met existing permit limits over the past year with one
exception of TSS. However, NH3-N has been steadily increasing
and is currently running close to 30 mg/l. It is therefore
recommended an NH3-N limit of 20 mg/1 (20x4 + 30BOD = 110 UOD)
be placed in the permit. The limit will provide justification
for repairing potential aeration deficiencies and require
improved sludge management.
It is recommended that a draft permit be prepared and placed
at public notice. If no significant adverse public comment is
received, it is recommended NPDES Permit No. NC0065480 be
reissued to Mr. Eddie Lewis in accordance with the Cape Fear
River basin -wide permitting strategy.
