Dear Mr. Neville:
The Division of Water Resources (the Division) hereby issues the attached NPDES permit for the subject facility.
This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the
Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated
October 15, 2007, or as subsequently amended.
The changes between this permit and the previous permit include the following:
• In accordance with the NPDES Permitting Strategy for WTP's (2009), facilities discharging greater than
50,000 gpd are required to install a continuous recorder to monitor wastewater discharge flows. As a
result, continuous flow monitoring has been added to your permit. The Town will have 18 months from
the effective date of this permit to install a continuous flow meter. Until then instantaneous
measurements can be taken with the duration of discharge to be noted in log books and a total daily
discharge reported on the DMR.
• The flow limit is removed.
• The coordinates for the Outfall 001 were adjusted to the following:
Latitude: 34° 46' 35" Longitude: 79° 19' 49"
• Turbidity monitoring is added with twice (2) per month monitoring.
• Total Iron monitoring is quarterly.
• Total Copper, Phosphorous, Nitrogen monitoring is added with quarterly sampling.
• Chronic Whole Effluent Toxicity testing is added with quarterly sampling in January, April, July and
October.
• The Fluoride limit 0.9 mg/L is one half ('/2) of the water quality standard of 1.8 mg/L for freshwater due
to the stream classification HQW [High Quality Waters].

A. (2.) CHRONIC TOXICITY PASS/FAIL MONITORING (QUARTERLY)
The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, 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. These months signify the first month of each three •
month toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be
obtained during representative effluent discharge and 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, DWR Form AT-1 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
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 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 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 Resources 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.

Fact Sheet
Renewal 2014 -- NPDES Permit NC0048577
Paw 1

Monthly average FLOW (MGD) — Last 36 months Mar2011-Feb2014:
[Ave 0.197 MGD; Maximum, Monthly average flow = 0.200 MGD]
Flow measurement was changed from Instantaneous to Continuous flow in accordance with NPDES
permitting strategies for potable water treatment plants. The maximum, monthly average discharge in the
most recent three year period (Mar2011-Feb2014) for this facility is 0.200 MGD (see attached spreadsheet
for flow data). Continuous monitoring is required for facilities discharging greater than 50,000 gpd. The
Permittee has 18 months from the effective date of this permit to install a flow meter to that is capable of
recording Continuous flow. Duration of discharge should be noted in log books and a Total daily discharge
reported on the DMR.
Toxicity — With an IWC >0.25%, this permit requires Chronic Whole Effluent Toxicity (WET) testing
using Ceriodaphnia dubia to be performed as a 7-day pass/fail test at 90% effluent concentration, during
January, April, July and October [TGP3B].
For Renewal — For Renewal — This permit reflects discharge at Outfall 001. DWR updated the facility
description and Map; added parameter codes to Section A. (1.); added Electronic Reporting - Discharge
Monitoring Reports page; added Turbidity 2/month; added continuous flow monitoring; added quarterly
monitoring for Total Copper, Phosphorous, Nitrogen; added limit with monthly monitoring for Fluoride;
monitoring for Total Iron changed to quarterly; and added Chronic Whole Effluent Toxicity testing.
Stream — Discharge from WTP for outfall 001 is into the Lumber River [Stream Segment 14-(4.5)]. The
segment is not currently listed as impaired in the 2012 North Carolina 303(d); however the 2012
Integrated Reports lists as Supporting Aquatic Life; Supporting Recreation; Impaired Fish Consumption
for Mercury.
RPA — A Reasonable Potential Analysis (RPA) was conducted on Iron and Fluoride effluent parameters data
because Discharge Monitoring Reports (DMRs) reported concentration above method -detection levels
(MDLs) for the past four and one half (4 1/2) years (Sept2009-Feb2014). [See attached RPA summary
sheets.]
• Fluoride did show reasonable potential to violate state WQS. Fluoride will be monitored monthly
with a limit of 900 µg/L while the WQS for Fluoride is 1800 µg/L, this standard is one half (1/2)
(900 µg/L) due to the stream class of HQW [High Quality Waters].

1 No later than begin submitting discharge monitoring reports electronically using NC DWR's eDMR application system. See
Special Condition A. (3.).
2 The Town will have until , approximately 18 months from the effective date of this permit, to install a continuous flow
meter. Until then instantaneous measurements can be taken with the duration of discharge to be noted in log books and a total daily
discharge reported on the DMR.
3 The Division shall consider TRC effluent values reported below 50 µg/L to be compliant with the permit. However, the Permittee shall
continue to record and submit all values reported by a North Carolina -certified laboratory method (including field certified), even if these
values fall below 50µg/L.
4 Compliance with this limit shall commence on , approximately 36 months from the permit effective date.
5 Samples shall be collected concurrently with WET -test samples.
6 Whole Effluent Toxicity (WET) testing - testing of Ceriodaphnia dubia shall be performed as 7-day pass/fail test at 90% effluent
concentration, during January, April, July and October [See A. (2.)].

Susan,
We will be adding Toxicity Testing to the Draft for NC0086894 Robeson Co-Raemon Well WTP. We have determined
that this system needs to be permitted using the Conventional WTP strategy instead of the previous Greensand. What
months for sampling should I put in the permit? I used January, April, July and October in the draft. I have two other
permits for Robeson County like this one that will need toxicity testing added.
Thanks,
Derek
