Subject: NPDES Permit Issuance
Permit No. NC0027103
Pembroke WWTP
Robeson County
Dear Mr. Cummings:
In accordance with the application for discharge permit received on June 2, 1999, the Division is
forwarding herewith the subject state - NPDES permit. 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 December 6, 1983.
Please note the following addition to the permit:
• There are currently 11 waters in the Lumber River Basin that have fish consumption advisories for
mercury, and appear as impaired waters on the North Carolina 1998 303(d) list. In order to
evaluate the relative contribution of mercury from NPDES point source dischargers, mercury
monitoring of effluent and sludge has been added to this permit. This data will then be used to
develop a mercury management strategy, by allocating allowable mercury loads to known sources
(both point and nonpoint). The ultimate goal of the mercury management strategy is to reduce fish
tissue mercury concentrations and eliminate the need for fish -consumption advisories in this basin.
• The effluent monitoring frequency for temperature has been modified from 3 times per week to
daily based on North Carolina Administrative Code 15A NCAC 2B .0508. This is the minimum
requirement for domestic dischargers into water quality limited streams, such as the Lumber
River.
• The instream monitoring requirement for conductivity has been deleted due to sufficient collection
of data for this parameter.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days
following receipt of this letter. This request must be in the form of a written petition, conforming to Chapter
150B of the North Carolina General Statutes, and filed with the office of Administrative Hearings, 6714 Mail
1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Telephone [phone]/FAX [phone]
An Equal Opportunity Affirmative Action Employer 50% recycled/ 10% post -consumer paper

Service Center, Raleigh, North Carolina 27699-6714. Unless such a demand is made, this permit shall be
final and binding.
Please take notice that this permit is not transferable. Part II, E.4. addresses the requirements to be
followed in case of change in ownership or control of this discharge. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Quality or permits
required by the Division of Land Resources, Coastal Area Management Act, or any other Federal or Local
governmental permits may be required.
If you have any questions or need additional information, please contact Ms. Jacquelyn Nowell at
telephone number [phone], extension 512.

SUPPLEMENT TO EFFLUENT LIMITATIONS
AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A (2). CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or
significant mortality to Ceriodaphnia dubia at an effluent concentration of 1.7 %.
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 January, April, July, and October. 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:

AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
(continued)
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.

HUA Project No. PM99O6
Dear Ms. Nowell:
OENR - WATER QUALITY
POINT SOURCE BRANCH
In reply to our telephone conversation regarding the subject NPDES permit renewal I
have reviewed our project file to determine why Page II-7 of the NPDES permit
application , item 15 Additional Wastewater Characteristics, was checked for the
additional parameters for :
Aluminum,
Arsenic,
Cadmium,
Chromium,
Copper,
Iron,
Lead,
Manganese,
Mercury,
Nickel,
Selenium,
Zinc.
These parameters are not contained in the sampling data for the effluent and the Town
does not have any industrial contributions to the sewer system. The Town did not
generate these data numbers for the project manager for HUA; however, in the review of
our files I came across the last sludge permit renewal and the sludge sampling data
Southern Pines, NC • Telephone [phone] • Fax [phone] • e-mail: [e-mail]

Ms. Jackie Nowell

contains these parameters. It appears our project manager inadvertently included these in
the NPDES permit application.
We are providing a revised sheet II-7 for the NPDES Permit, which reflects none of these
parameters checked as present in the Town of Pembroke's effluent. We have discussed
this matter with both the Town and the Fayetteville Regional Office and they concur that
none of these parameters are known to be in the wastewater effluent.
If you have any further questions about this matter please call me.

Permit Notes
NC0027103
The Town of Pembroke is requesting renewal of existing permit. The facility discharges
to the Lumber River and this segment is listed on the 1998 303(d) list due to a fish
consumption advisory for mercury. The stream classification is WS-IV and B Swamp
HQW. The plant has recently been upgraded to 1.33 MGD. Previous design capacity
was 0.82 MGD. Current limits are as follows:
BOD5 18 mg/1
NH3 12 mg/1
TSS 20 mg/1
DO 5 mg/1
Fecal 200/100m1
Chlorine 28 ug/1
Chronic Toxicity at 1.7%, (JAN APR JUL OCT)
The Pembroke WWTP appears to be a well operated plant. They have consistently met
most limits during the period of 1997 through 1999. A review of DMR data indicates
some violations of the TSS limit of 20 mg/1 with exceedances of the limit occurring in
Dec. 1998, August and Sept. 1999. There was one violation of the NH3 limit in Nov.
1998. Besides these recent violations, there have been no apparent problems with the
Pembroke facility.
There are currently 11 waters in the Lumber River Basin that have fish consumption
advisories for mercury, and appear as impaired waters on the North Carolina 1998 303(d)
list. In order to evaluate the relative contribution of mercury from NPDES point source
dischargers, mercury monitoring of effluent and sludge has been added to this permit.
This data will then be used to develop a mercury management strategy, by allocating
allowable mercury loads to known sources (both point and nonpoint). The ultimate goal
of the mercury management strategy is to reduce fish tissue mercury concentrations and
eliminate the need for fish -consumption advisories in this basin. Will add quarterly
effluent monitoring and semi-annual sludge monitoring for mercury to the Pembroke
permit.
There is one issue that needs to be addressed. A review of the application indicated the
presence of several toxicants in the effluent, including aluminum, arsenic, cadmium,
chromium, copper, iron, lead, manganese, mercury, nickel, selenium and zinc. The
last WLA done in 1994 indicated that the facility was 100% domestic wastewater. This
info in the application indicates some type of industrial contributor to the plant. Will
confer with FRO to determine the source of these toxicants.
12/2/99 - Called Belinda Henson of FRO (she did the last staff report) and asked if she
had any idea about the Pembroke discharge. 12/7/99 - B. Henson returned call and said
that the only industry going into Pembroke was a bakery and there should be no metals or

anything in the wastestream. A few years back there was a machine shop but it was no
longer there. Does not understand where these metals and toxicants could be coming
from.
12/2/99 - Called Mike Wicker of Hobbs & Upchurch
12/7/99 - Called Town of Pembroke spoke to Karen Dial of their lab. She indicated that
the facility was 100% domestic wastewater. Hobbs and Upchurch Engineers prepared
the application for renewal and she had not seen it. She asked that I fax her a copy of the
application sheet that indicated that there were several metals, etc. present in their
effluent and she would call after reviewing it.
12/8/99 — Karen Dial of Pembroke called said that the sheet represented data that
definitely not their effluent. She's unsure where Hobbs and Upchurch's info came from,
but this was a gross error. Wants to complete another sheet to modify the application.
Told her I would check with supervisor, about what needed to be done to correct the
situation. Two recommendations from EEIIs, 1) have Pembroke run a sample of effluent
and test for each parameter that was denoted as present in the effluent. 2) Have the
mayor sign a certification/verification statement that these constituents are not present in
the effluent and place it in the Pembroke file.
Staff meeting recommendation for Pembroke situation: 1) Give them opportunity to
complete a new application, and they must explain the error made, 2) If explanation is not
clear, then they must sample effluent, 3) check with Pretreatment to see if there is any old
data, info etc.
Will send copy of new app to Karen Dial of Pembroke. P.O. Box 866 Pembroke NC
28372
12/21/99 - Received a letter from Mike Wicker, he revised the application for
Pembroke by sending in a letter that indicated that Pembroke's effluent did not
contain any metals. The sludge analysis report contains the metals data and it
appears that the Hobbs, Upchurch project manager inadvertently included the
sludge data in the NPDES permit application. Attached the sludge sampling sheet
that shows the presence of Al, Mg, Cu, Zn, Cd, Cr, Ni, Pb, As, Hg, and Se. The
same parameters that the NPDES application says are present in the effluent.
Will accept the revised application and continue the renewal process for Pembroke.
Will recommend renewal of the Pembroke permit with all existing limits and
monitoring requirements. Must include language and quarterly effluent monitoring
for Hg (with a specified 0.2 ug/1 detection limit) and semi-annual monitoring fo
sludge ( with a specified 0.1 mg//kg detection limit, dry weight basis) for TMDL that
must be developed for problem streams in Lumber River Basin.
