Subject: Issuance of NPDES Permit NC0026352
Town of Bladenboro
Bladenboro WWTP
Bladen County
Dear Mayor Duckworth:
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 draft permit include the following:
• Mercury EPA Method 1631E sampling type is grab.
Responses to the four (4) modifications you have requested to be made to the draft permit include the
following:
1. Request: The permit currently has a monthly permit limit for mercury. In accordance with
Footnote 6, it is requested that the monitoring frequency for mercury be reduced to quarterly
with no permit limit. A review the monitoring data for the past twelve months shows the
mercury levels to below 12 ng/L."
Response: Your mercury monitoring schedule has been reduced to one sample collected
during the next permit cycle, in accord with DWR's Implementation of 2012 Statewide TMDL
plan applied to all discharges in the Lumber River Basin. This requires one Low-level mercury
analysis using EPA Method 1631E to be submitted with the next permit renewal.
2. Request: The Town requests that quarterly monitoring for Chronic Toxicity be removed from
the permit. In your online guidance, there is an August 2, 1999 memorandum that states that
toxicity testing will be required at "major" facilities or those facilities discharging "complex"
wastewaters. The flow to the WWTP is a combination of domestic discharges from residential
and commercial sources with no industrial contributions and should not be subject to the
toxicity requirement."

Response: In 2004, DWR negotiated with the Town of Bladenboro the option to perform
quarterly Chronic Toxicity tests in lieu of lower, more stringent permit limits for Ammonia
(NH3 as N) considering a 100%-domestic discharge under zero -flow stream conditions.
Therefore, in accord with currently active permitting strategy statewide for Ammonia, the
removal of WET testing will require DWR to reinstate the need for lower Ammonia limits to
protect the receiving stream for acute impacts. These new limits are:
• Winter - 4.3 mg/L (monthly average) / 12.9 (Weekly Average)
• Summer - 1.0 mg/L (monthly average) / 3.0 (Weekly Average)
Having reviewed the monitoring data for Ammonia submitted during the last permit cycle,
DWR feels the WWTP can comply with new ammonia limits provided that the plant is
operated with the same due diligence.
3. Request: It is requested that upstream/downstream monitoring for temperature and dissolved
oxygen be eliminated. The effluent discharges into a swampy area. We feel there is no useful
determination that can be made regarding plant efficiency by comparing the
upstream/downstream samples. The upstream flow is subject to urban runoff and the whole
drainage area is subject to agricultural influences.
Response: The Division has reviewed your effluent Temperature and Dissolved Oxygen (DO)
data for the last two years (Apr2012 to Mar2014), and compared these data to the receiving
stream (upstream and downstream). Based on our analysis, we do not agree that "there is no
useful determination that can be made regarding plant efficiency by comparing the
upstream/downstream samples." Temperature is consistently higher in the effluent,
particularly in the winter season. However, the Division is more concerned about DO as we
must consider temperature to normalize concurrent DO readings. The range of reported
effluent DO is broad [5.03 mg/L to 11.12 mg/L]. The water -quality standard for DO is 5.0
mg/L and monitoring both effluent and in -stream DO is warranted to determine impact to this
standard. Therefore, the Division did not change the permit.
4. Request: It is requested that the effluent temperature requirement be changed from daily to
weekly.
Response: Daily sampling [5-day week] for effluent temperature is consistent with current
permitting strategies statewide and with operator and visitation requirements for a facility
classified Grade II (< 0.5 MGD). Therefore, the Division did not change the permit.
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
specify that, if a state does not establish a system to receive such submittals, then permittees must submit
DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates that these
regulations will be adopted and is beginning implementation.
The requirement to begin reporting discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application has been added to your NPDES
permit. [See Special Condition A. (2.)] For information on eDMR, registering for eDMR and obtaining
an eDMR user account, please visit the following web page:

If any parts, measurement frequencies, or sampling requirements contained in this permit are
unacceptable, you have the right to an adjudicatory hearing, upon written request submitted within thirty
(30) days after receiving this letter. Your request must take the form of a written petition conforming to
Chapter 150B of North Carolina General Statutes, and you must file it with the Office of Administrative
Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such a demand is
made, this permit shall remain final and binding.
This permit is not transferable except after notifying the Division of Water Resources. The Division may
require permit modification, or revocation and re -issuance. Please note that this permit does not affect
your legal obligation to obtain other permits required by the Division of Water Resources, the Division of
Land Resources, the Coastal Area Management Act, or other federal or local governments.

following address:
NC DENR / DWR / Information Processing Unit
ATTENTION: Central Files / eDMR
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1.1, 2, 3) or
alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
mailing address above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be
submitted in writing to the Division for written approval at least sixty (60) days prior to the date the
facility would be required under this permit to begin using eDMR. Temporary waivers shall be valid
for twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted
electronically to the Division unless the permittee re -applies for and is granted a new temporary
waiver by the Division.

Applicant is not requesting modification of the facility or increasing flow at this time.
John E. Skvarla, III
Secretary
A rating sheet is not attached as no modifications were made to this facility during the previous permit
cycle.
A review of compliance data revealed several minor fecal coliform, BOD and flow violations for 2012
and 2013 but no chronic violations.
Based on the previous NPDES Compliance Inspection, there are no modifications of the treatment works
necessary at this time, however, a new flow meter does need to be installed.
No special conditions, limitations, or monitoring is suggested at this time.
Based on the above information, the Fayetteville Regional Office recommends reissuance in keeping with
the current basin wide strategy.

In -Stream DO Assessment instructions -
Shaded areas require user inputs. If salinity and/or elevation are unknown and cannot be
determined then leave blank, this will not affect the final outcome. After entering data
drag the DO saturation cells, percent saturation cells, and impact assessment cells
down to the appropriate line.
Note: that if salinity or elevation values are not enter then the DO saturation values only
represent the temperature corrected values only.

Shaded areas require user inputs. If salinity and/or elevation are unknown and cannot be
determined then leave blank, this will not affect the final outcome. After entering data
drag the DO saturation cells, percent saturation cells, and impact assessment cells
down to the appropriate line.
Note: that if salinity or elevation values are not enter then the DO saturation values only
represent the temperature corrected values only.

Subject: NPDES Permit Renewal
Town of Bladenboro
NPDES Permit #NC0026352
Bladen County
Dear Permitting Unit:
The Town of Bladenboro is submitting the renewal application for NPDES permit #NC0026352.
The permit application consists of:
Cover letter
One original of Form 2A — NPDES Application for Permit Renewal
Topographic Map
Process Flow Schematic
Two copies of Form 2A — NPDES Application for Permit Renewal
The Town would like to request that the following modifications be made to the permit:
The permit currently has a monthly permit limit for mercury. In accordance with
Footnote 6, it is requested that the monitoring frequency for mercury be reduced to
quarterly with no permit limit. A review of the monitoring data for the past twelve
months shows the mercury levels to be below 12 ng/1.
The Town requests that quarterly monitoring for Chronic Toxicity be removed from the
permit. In your online guidance, there is a August 2, 1999 memorandum that states that
toxicity testing will be required at "major" facilities or those facilities discharging
"complex" wastewaters. The flow to the WWTP is a combination of domestic discharges
from residential and commercial sources with no industrial contributions and should not
be subject to the toxicity requirement.
411 Ivey Street * Post Office Box 455 * Bladenboro, NC 28320
Phone [phone] * Fax [phone]

It is requested that upstream/downstream monitoring for temperature and dissolved
oxygen be eliminated. The effluent discharges into a swampy area. We feel there is no
useful determination that can be made regarding plant efficiency by comparing the
upstream/downstream samples. The upstream flow is subject to urban runoff and the
whole drainage area is subject to agricultural influences.
It is requested that the effluent temperature requirement be changed from daily to weekly.
We thank you for your consideration in these matters. If you have any additional questions or
comments, please call me at 910/863-3655.
Sincerely,
u4 QuocL
