NC0032565_Draft Fact Sheet_20230524

FACT SHEET FOR EXPEDITED PERMIT RENEWALS
This form must be completed by Permit Writers for all expedited permits which do not require
full Fact Sheets. Expedited permits are generally simple 100% domestics (e.g., schools, mobile
home parks, etc.) that can be administratively renewed with minor changes but can include
facilities with more complex issues (Special Conditions, 303(d) listed water, toxicity testing,
instream monitoring, compliance concerns).

No
For whatparameter?
Any obvious compliance concerns?
Sixteen enforcements during this permit cycle,
along with twenty-three NOVs and one NOD.
An examination of flow violations has
determined the facility was reporting
incorrectly, which led to the appearance of
flow exceedances.
An inspection of the facility was
conducted on January 31, 2023. The
inspection revealed that the WWTP
requires significant
maintenance/repair/upgrade or
replacement if permit limits are to be met
on a consistent basis. However, even in its
current state, it appeared possible that the
existing system could perform in
compliance but for the state of the influent
it receives. The influent was unusually
clear and did not bring enough food source
to the system to promote good biological
activity in the activated sludge process.
Under these circumstances, it will be very
difficult for the facility to meet ammonia
nitrogen effluent limits. It appeared that
the operator of the WWTP coaxed its best
performance from the existing system, but

it was obvious that the permittee must
invest more into system maintenance.
Positive developments occurred just prior
to and following the inspection. The
school system has significant funding
devoted to the future of wastewater
treatment. The school system has been in
continuing discussions with a reputable
engineering firm that has guided them in
an examination of possible solutions and
the recommendation of one in particular.
They are going to recommend
construction of a pump station and sewer
force main to connect the school to the
City of Kinston collection system. They
further recommend entry into the SOC to
cover the school during the time period of
construction.
Any permit modifications since the last
None.

Most Commonly Used Expedited Language:
• 303(d) language for Draft/Final Cover Letters: "Please note that the receiving stream
is listed as an impaired waterbody on the North Carolina 303(d) Impaired Waters List.
Addressing impaired waters is a high priority with the Division, and instream data will
continue to be evaluated. If there is noncompliance with permitted effluent limits and
stream impairment can be attributed to your facility, then mitigative measures may be
required".
• TRC language for Compliance Level for Cover Letters/Effluent Sheet Footnote:
"The facility shall report all effluent TRC values reported by an NC certified laboratory
including field certified. However, effluent values < 50 µg/l will be treated as zero for
compliance purposes."
