The effluent concentration defined as treatment two in the procedure document is 90%. The testing shall be
performed as a Ceriodaphnia dubia 7day 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.

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 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 Section at

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 than 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.

Transmittal of Application Package
NC0086941 —Modification Request
Wayne County
Dear Mr. Weaver:
Enclosed please find the original plus two copies of the following:
A. Check Number 5924 in the amount of$260.00 made payable to NC DENR.
B. The originally submitted application package minus the copy of the NPDES Permit.
As we discussed by phone, we were previously advised by phone that no permit fee would be
required. We have lost two plus weeks. In practical terms, this permit will result in no realized additional
flow to the stream. Since August of 2005, the existing facility has had no discharge. The capability to
discharge is required by NC Public Water Supply. It is noted that the existing permit has no flow limit,
and it is anticipated that there will be no flow limit associated with the revised permit. Since no"flow"
increase is represented in the effluent page, we request that you consider using the shortest available
permitting process. We have three USDA Funded water related projects that are awaiting issuance of this
permit.
Should you have any questions related to this request, please give me a call.
Sincerely,

Subject: NPDES Permit Minor Modification
NPDES Permit No.NC0086941
Southeastern Wayne Sanitary District
Wayne County,NC
Dear Mrs. Sprinkle:
This letter will serve as Southeastern Wayne Sanitary District's request for minor modification of
our NPDES Permit NC0086941. A speculative limits letter was issued on February 12,2010,which
supports doubling the size of the existing potable water treatment plant and its associated discharge. The
additional effluent page,which reflects this expansion,must be received prior to the District
receiving critical funding for three water related projects.
Southeastern Wayne Sanitary District will be increasing the size of the potable water treatment
plant from 0.9 MGD to 1.62 MGD. The quantity of wastewater will increase from 33,000 gpd to 66,000
gpd as a result of the expansion.The proposed water treatment plant expansion involves mirroring the
existing facilities on-site to include:three new iron sand filters,equal in capacity to the existing three iron
sand filters;filter backwash; ammonia addition at the wells for chloramine disinfection;two waste tanks
for solids settling,blending of decanted water with raw water coming into the plant; and dechlorination
with calcium thiosulfate,should the facility need to discharge. Discharge from the mirrored portion of the
facility will join with the existing facility, and utilize the existing discharge pipe.
As a reminder,there has been no discharge from this facility since August 2005. In lieu of
discharge,the water will continue to be blended with raw water coming into the plant. However,the
District must maintain the ability to discharge. Please find attached the following items:
1. A copy of the February 12,2010, speculative limits letter
2. A copy of the NPDES Permit No.NC0086941, issued on June 28,2011
3. Flow Schematic,and
4. Residuals Management Plan
On or about October 22,2008,this office requested to be decertified, since we were not
discharging. There is an agreement with the City of Goldsboro to analyze any samples until we are
recertified,in the event we need to resume discharging.

Southeastern WaYneSanitary District
Devil's Woodyard Water Plant
Residuals Management Plan
NPDES Permit No.NC0086941
Ouantity Generated
Residuals,to be handled come from the backwashing of iron filters. It is anticipated that approximately
that 1 mg/1 of iron will be removed.
Annual Iron Removal = 365 days x 1.62 MGD x 8.43 x 1 mg/1
• 4932 lbs.
• 4,932 lbs. / 140 lbs/ft3
35.2 ft3 per year
Residuals Handling and Storage
Backwash from the iron filters is distributed to four 40' by 20'waste settling tanks where the solids
precipitate out.
Depth of Residuals = Annual Residuals/Tank Area
Within Tanks
• 35.2 ft3/(4 x 40'x 20')
• 0.011' deep
• 0.132"deep
Adequate storage is available.
Ultimate Disposal or Reuse
Residuals do not have to be removed frequently. They are being handled under contract with Granville
Farms,Inc,Post Office Box 1396,Oxford,NC 27565. The last time residuals were removed was March
2008. Attached is a copy of the chemical analysis of the residuals.
