1. For instantaneous flow monitoring the duration of the discharge must bel eported.
2. The Division shall consider all effluent TRC values reported below 50 ug/I: to be in compliance with the
permit. However, the Permittee shall continue to record and submit all values reported by a North Carolina
certified laboratory (including field certified), even if these values fall below 50 ug/I.
3. Facilities using chloramination will be required to monitor ammonia nitrogen on a quarterly basis.
4. Parameters should be monitored in conjunction with toxicity test.
5. Zinc should be monitored if facility uses zinc orthophosphate as a corrosion inhibitor.
6. Fluoride monitoring applies if the facility backwashes with fluoridated, finished water.
7. See Special Condition A. (2.).
All samples collected should be from a representative discharge event.
There shall be no discharge of floating solids or visible foam in other than trace amounts.

Permit NC0088200
A (2.) CHRONIC TOXICITY MONITORING (QRTRLY)
The permittee shall conduct Quarterly chronic toxicity tests using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent
versions.
The effluent concentration defined as treatment two in the procedure document is 90%. The testing
shall be performed as a Ceriodaphnia dubia 7 day pass/fail test. The tests will be performed during
the months of January, April, July and October. Effluent sampling for this testing shall be
performed at the NPDES permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter code
TGP3B. Additionally, DWQ Form AT-1 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh,N.C. 27699-1621
•
•
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later •
than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. 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 indidating 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 Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then
monthly monitoring will begin immediately. Upon submission of a valid test, this monthly test
requirement will revert to quarterly in the months specified above.
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.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT
Forms submitted.
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.

Notes on Preparation of Permit Renewal for NC0088200
No effluent has been discharged from the lagoon since the middle of March 2008. No waste has been
sent to the lagoon since late February 2008. Currently the water plant alum waste is transported through
the sanitary sewer to the Thomasville WWTP.
Sludge Management Plan
This facility does not currently have a sludge management plan, however several companies have been
approached to provide solutions for long term sludge management at this facility. Some options include
using the material as an amendment in the manufacture of bricks, or as an amendment to composting
materials (if it can be verified that this meets the 503 regulations). Additional funding has been requested
for further study of the options. The City is still evaluating options for resolution to the sludge removal
and disposal issue. A sludge management plan will be developed once all options have been evaluated
and before the lagoon is to be put back in service. In the mean time, sludge generated by the City's Water
Plant from alum treatment of the water, will be treated and disposed of through the City's Wastewater
Plant. Sludge disposal through the WWTP is handled by landfill of sludge at a Subtitle D lined landfill or
through land application under 503 regulations.

YESThis is a SIMPLE EXPEDITED permit renewal (administrative
renewal with no changes, or only minor changes such as TRC, NH3,
name/ownership changes). Include conventional WTPs in this group.
YESVThis is a MORE COMPLEX EXPEDITED permit renewal (includes
Special Conditions (such as EAA, Wastewater Management Plan), 303(d)
listed, toxicity testing, instream monitoring, compliance concerns, phased
limits). Basin Coordinator to make case -by -case decision.
YES This permit CANNOT BE EXPEDITED for one of the following reasons:
• Major Facility (municipal/industrial)
• Minor Municipals with pretreatment program
• Minor Industrials subject to Fed Effluent Guidelines (lb/day limits for BOD, TSS,
etc)
• Limits based on reasonable potential analysis (metals, GW remediation organics)
• Permitted flow > 0.5 MGD (requires full Fact Sheet)
• Permits determined by Basin Coordinator to be outside expedited process
