Permit Number: NC0023981
A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 44%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the
"North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or
subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised -February 1998) or subsequent versions. The tests will be performed during the months of
February, May, August, November. Effluent sampling for this testing shall be performed at the NPDES
permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the
permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two
following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are
specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -
February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter
code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3
(original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later
than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if
chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test
form indicating the facility name, permit number, pipe number, county, and the month/year of the report
with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the
Environmental Sciences Branch at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring
will be required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division
of Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls,
shall constitute an invalid test and will require immediate follow-up testing to be completed no later than
the last day of the month following the month of the initial monitoring.

The facility has been consistently passing its WET tests.
COMPLIANCE SUMMARY:
DMRs have been reviewed for the period January 2001 through September 2004. The facility has a negative
compliance record. During the review period, the following NOVs (notices of violation) have been issued:
08/26/04 - Pb, 8/04/04 - Pb, 6/12/04 - Cr, Pb, 6/21/04 - Pb, 5/16/04 - Pb, 2/16/04 - for not using new

2/10/03 - Pb and TRC, 4/29/03 - BOD, TSS, Pb, 1/14/02 - fecal and Pb, 12/18/02 - Pb, DO, pH,
10/04/02 - fecal, 7/05/02 - Se, Pb, 5/17/02 - Se, 2/18/02 - Se, 9/25/01- TRC and Se, 5/19/01- TSS.
A compliance evaluation inspection conducted on May 4, 2004 found that the facility is well kept and is in
compliance.
INSTREAM MONITORING:
Instream monitoring is required for temperature, dissolved oxygen, fecal colifomi, and conductivity. An
analysis of DO, temperature and conductivity data showed that the facility may has no noticeable negative
impact on stream water quality (table is attached).
PROPOSED CHANGES:
• MoratoringFnquerxi s: Monitoring for cadmium has been reduced to 2/Month due to the elimination of
the limit.
• Limi Based on the Reasonable Potential Analysis, the limit for cadmium has been eliminated. In
addition, weekly average limits for ammonia nitrogen have been added to the permit.
• Priority pollutant monitoring on an annual basis has been added to fulfill the permit application
requirement in the future.
Existing permit limits and recommended limits/monitoring are summarized in the table below:

The existing monitoring frequency for silver, zinc, and copper remains unchanged. Due to the facility's
toxicity record, limits for these action level standards will not be implemented, but monitoring will remain.
All other parameters evaluated showed no reasonable potential to exceed the instream water quality limits or
federal criteria.

Subject: Permit Renewal Request for the City of Lenoir — Lower Creek
WWTP (Permit # NC0023981) and Sludge Management
Plan for the Facility
Dear Mrs. Stephens:
The City of Lenoir would like to request renewal of the NPDES wastewater
discharge permit for the Lower Creek WWTP (Permit # NC0023981). The
current permit expires on February 28, 2005.
There have been no major changes at the facility since issuance of the last
permit (effective date June 1, 2001). However, due to numerous
operational problems, the dissolved air flotation tank (DAF) has been taken
out of service.
Sludge is thickened by turning off the return sludge pump. The thickened
sludge is pumped directly from the bottom of the clarifier to sludge holding
tank. Under normal operation the sludge holding tank has mixing provided
(no aeration in this process). This sludge is mixed with sludge transported
from the Lenoir Water Plant (alum sludge) and from the Gunpowder Creek
WWTP.
The Lower Creek WWTP Biosolids Facility is a "Class A" sludge treatment
facility, which currently utilizes lime stabilization and pasteurization
processes. Sludge from the holding tank is pumped onto a belt press at
approximately 2% solids content. The press discharge is about an 18%
solids cake. This sludge cake is augured into a thermoblender, where

quicklime is fed and heat is applied. After this heating and mixing step, the
product drops into the pasteurization vessel, where it is heated to at least
158°F for thirty minutes. The final product, called "Lenoir Blend" is
conveyed to a dump truck, which dumps the biosolids onto a storage pad.
Lenoir Blend is given to local farmers or is spread directly onto their fields
by city personnel and city spreader truck. Sludge analysis on this final
product is generally conducted four times per year, and includes nutrients,
metals and fecal coliform bacteria.
With the exception of effluent lead values (current permit limit — 33.8 pg/L
daily maximum) during the July 2003 — June 2004 period, the plant has
been reasonably compliant. Revamping the chlorination system in the
plant solved the fecal coliform problems during August and September
2003. We have been working with the State Pretreatment Unit to help
resolve the source of lead. However, we have found no significant source
of lead contribution within industrial users, contributing sewer lines or plant
recycle flows. Operating the plant at lower MLSS seems to be the only
hope of reducing effluent lead. So far this year (2004) we have been
successful in reducing MLSS in half (see attached chart and graph), but
effluent lead values have not changed drastically (Note: The ideal MLSS
during summer months should be around 1500 mg/L, about 60% of our
current values). We are planning on expanding the "Class A" biosolids
treatment during the 2005-2006 fiscal year, which should give us more
flexibility in basin solids level control. We trust that the permit limit issued
for lead for the upcoming permit will be as liberal as possible, while still
protecting the water quality of Lower Creek and the Catawba River.
If you require any other information, please call me at 828-757-2198.
Thank you for your assistance.
Sincerely,

Sampling, preservation, and analytical method must be from 40 CFR 136.
* Graphite Furnace Determinations are required to attain the desired detection level for the
metals. However, analysis of Aeration Basin and Sludge to Disposal samples often cannot meet
these detection levels. In this case, analysis of these samples must obtain a detection level at
least as stringent as the applicable inhibition criteria or sludge ceiling standard.
** All Aeration Basin and Sludge to Disposal samples will be grab.
