Dear Mayor Hardaway:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge 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 May 9, 1994 (or as subsequently
amended.) The following modifications have been made to the permit:
• The deletion of instream monitoring for fecal coliform and conductivity based on new Division of
Water Quality (DWQ) procedure. Effluent monitoring for conductivity will also be deleted.
• Effluent monitoring for MBAS will be deleted. Reasonable potential analysis indicated that the
allowable concentration of 6950 ug/l would not be exceeded.
The following condition is included in the permit: Limits on total phosphorus and total nitrogen have
not been included at this time because the facility is participation in the nonpoint source trading option
outlined in the Tar Pamlico NSW implementation Strategy Phase II, which was adopted December 8,
1994. If compliance with any element of this strategy, or subsequent approved revisions to the strategy
is not maintained, the Division reserves the right to reopen this permit to include nutrient limits. If
requirements other than those listed in this NPDES permit are adopted as part of a future revision to
the strategy, the Division reserves the right to reopen this permit to include these requirements.
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
Service Center, Raleigh, North Carolina 27699-6714. Unless such a demand is made, this permit shall be
final and binding.

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 7.0%.
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 February, May, August, and November. 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 pap/fail results and THP3B
for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Water Quality
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30 days after the
end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature. 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 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.

SUMMARY OF FACILITY AND WASTELOAD ALLOCATION
The Town of Enfield is requesting renewal of the existing permit. The facility is a 1.0 MGD
extended aeration plant. The receiving stream is Fishing Creek with a s7Q10 = 20 cfs,
w7Q10 = 53.5 cfs and QA = 526 cfs. The stream class is C NSW. Fishing Creek (030304)
is not on the final draft 2000 303(d) list. (Fishing Creek in Tar01 is listed on the 303d
list.) In June 1998, DWQ received an engineering certification indicating an expansion from
0.5 MGD and a relocation of the outfall to Fishing Creek. Enfield relocated to Fishing Creek
from a low flow stream (Beech Branch), where the previous IWC was 88%. The IWC at
Fishing Creek is 7%.
Existing effluent limits are 15/3/5 (summer) and 30/6/5 (winter). Fecal coliform at 200/100m1
and chlorine at 28 ug/1 are also limited. There is monthly monitoring of TN and TP, twice per
month monitoring of MBAS, and a quarterly Chronic toxicity P/F test at 7% in Feb May Aug
and Nov. Application lists one contributor of industrial waste, Safelite Glass Corp.
Because this discharger is located in the Tar Pamlico River Basin, which has the NSW
classification, there are rules and recommendations to reduce nutrient loads to the estuary
from both point and nonpoint sources of pollution. The Town of Enfield is a member of
the Tar Pamlico Basin Association. The following language must be placed in the permit
of Association members as a condition:
Limits on total phosphorus and total nitrogen have not been included at this time because the
facility is participattert in the nonpoint source trading option outlined in the Tar Pamlico
NSW implementatio Strategy Phase II, which was adopted December 8, 1994. If compliance
with any element of this strategy, or subsequent approved revisions to the strategy is not
maintained, the Divis'on reserves the right to reopen this permit to include nutrient limits. If

requirements •other than those listed in this NPDES permit are adopted as part of a future
revision to the strategy, the Division reserves the right to reopen this permit to include these
requirements.
NPDES Guidelines: There will be no nutrient limits and no offset payments.
TOXICITY TESTING:
Requirement:
renewed with permit
Chronic Toxicity (Ceriodaphnia) @ 7%; FEB MAY AUG DEC - Will be
COMPLIANCE SUMMARY:
According to the Compliance Evaluation Analysis Report through March 2000, there were no
violations of the existing permit limits. In 1999, there were two violations of flow, and one violation
each of TSS, fecal, and pH. In 1998, there were two violations of flow, three violations of NH3, and
two violations of fecal coliform. In 1997, there was one violation each of flow, BOD5, TSS, and two
violations of pH.
INSTREAM MONITORING:
Upstream monitoring at NC SR1222; Downstream monitoring at NC SR1109
Instream data for 1997, 1998, 1999 looked very good. DOs stayed in 9-10 mg/1 range from April —
October. Instream monitoring for Temperature and dissolved oxygen is continued. Instream
monitoring for fecal coliform and conductivity has been deleted per DWQ policy.
PROPOSED CHANGES:
The following modifications have been made to the permit:
• Instream monitoring for fecal coliform and conductivity will be deleted. Effluent
monitoring for conductivity will also be deleted.
• Effluent monitoring for MBAS will be deleted. Reasonable potential analysis indicated
that the allowable concentration of 6950 ug/1 would not be exceeded.
PROPOSED SCHEDULE FOR PERMIT ISSUANCE:
Draft Permit to Public Notice: 08/30/2000
Permit Scheduled to Issue: 10/23/2000

Background
The Town of Enfield is requesting renewal of the existing permit. The facility is a 1.0 MGD
extended aeration plant. The receiving stream is Fishing Creek with a s7Q10 = 20 cfs,
w7Q10 = 53.5 cfs and QA = 526 cfs. The stream class is C NSW. Fishing Creek (030304)
is not on the final draft 2000 3O3(d) list. (Fishing Creek in Tar01 is listed on the 303d
list.) In June 1998, DWQ received an engineering certification indicating an expansion from
0.5 MGD and a relocation of the outfall to Fishing Creek. Enfield relocated to Fishing Creek
from a low flow stream (Beech Branch), where the previous IWC was 88%. The IWC at
Fishing Creek is 7%.
Existing effluent limits are 15/3/5 (summer) and 30/6/5 (winter). Fecal coliform at 200/100m1
and chlorine at 28 ug/1 are also limited. There is monthly monitoring of TN and TP, twice
per month monitoring of MBAS, and a quarterly Chronic toxicity P/F test at 7% in Feb May
Aug and Nov. Application lists one contributor of industrial waste, Safelite Glass
Corp.,which submitted product and material safety data sheets.
Because this discharger is located in the Tar Pamlico River Basin, which has the NSW
classification, there are rules and recommendations to reduce nutrient loads to the estuary
from both point and nonpoint sources of pollution. The Town of Enfield is a member of
the Tar Pamlico Basin Association. The following language must be placed in the permit
of Association members as a condition:
Limits on total phosphorus and total nitrogen have not been included at this time because the
facility is participation in the nonpoint source trading option outlined in the Tar Pamlico
NSW implementation Strategy Phase II, which was adopted December 8, 1994. If compliance
with any element of this strategy, or subsequent approved revisions to the strategy is not
maintained, the Division reserves the right to reopen this permit to include nutrient limits. If
requirements other than those listed in this NPDES permit are adopted as part of a future
revision to the strategy, the Division reserves the right to reopen this permit to include these
requirements.
NPDES Guidelines: There will be no nutrient limits and no offset payments.
Compliance Evaluation Analysis Review
Through March 2000, there were no violations of the existing permit limits.
In 1999, there were two violations of flow (Sept. and Oct.'99), and one violation each of TSS,
fecal, and pH. From April 1999 to March 2000, avg. Qw = 0.676 MGD which is 67% of design
capacity. During this same time frame, averages for BOD5 =2.4 mg/1, TSS = 11.1 mg/1, NH3=
0.36 mg/1, TN = 14.9 mg/1 and TP=1.3 mg/1.
In 1998, there were two violations of flow (January and February), three violations of NH3
(April -June), and two violations of fecal coliform. From April 1998 to March 1999, avg. Qw =
0.523 MGD, approximately 52% of design capacity. During this same time frame, averages
for BODS =6.14 mg/1, TSS = 8.7 mg/1, NH3= 1.9 mg/1, TN = 8.7 mg/1 and TP=1.2 mg/1.
In 1997, there was one violation each of flow, BOD5, TSS, and two violations of pH. From
April 1997 to March 1998, avg. Qw = 0.571 MGD, approximately 57% of design capacity.
During this same time frame, averages for BODS =11.0 mg/1, TSS = 14.4 mg/1, NH3= 5.1

Toxicity Test Results
Facility appears to have passed all tox tests since the relocation in June 1998. There have
been some late reports but no FAILS. There was some problem in the past with the facility
not sampling during the designated months of Feb May Aug Nov. Also, self monitoring
reports are due no later than 30 days after the end of the recording period.
Instream Monitoring Data
Upstream monitoring at NC SR1222; Downstream monitoring at NC SR1109
Instream data for 1997, 1998, 1999 looked very good. DOs stayed in 9-10 mg/1 range from
April - October.
Recommended continuation of instream monitoring for dissolved oxygen and temperature.
Instream monitoring for fecal coliform and conductivity will be deleted from the permit, per
new DWQ policy.
Recommendations:
• Renewal of existing limits of 15/3/5 (summer) and 30/6/5 (winter), with fecal
limit of 200/ 100m1 and Cl limit of 28 ug/1.
• Instream monitoring for dissolved oxygen and temperature will be continued.
• Instream monitoring for fecal coliform will be deleted and effluent and
instream monitoring for conductivity will be deleted.
• Effluent monitoring for MBAS will be deleted. Reasonable potential analysis
for data in 1999 and early 2000 indicated that the allowable concentration of
6950 ug/1 would not be exceeded.
• To be inserted in the permit: For Association members:
Limits on total phosphorus and total nitrogen have not been included at this time because the facility
is participating in the nonpoint source trading option outlined in the Tar Pamlico NSW
implementation strategy Phase II, which was adopted December 8, 1994. If compliance with any
element of this strategy, or subsequent approved revisions to the strategy is not maintained, the
Division reserves the right to reopen this permit to include nutrient limits. If requirements other
than those listed in this NPDES permit are adopted as part of a future revision to the strategy, the
Division reserves the right to reopen this permit to include these requirements.

SUBJECT: Effluent Toxicity Testing
NPDES Permit No. NC0025402
Town of Enfield WWTP
Halifax County
Dear Mr. Davis:
This letter is to confirm several issues concerning whole effluent toxicity testing which
were discussed during a telephone conversation between Mr. David Lynch, ORC for Enfield, and
me on June 10, 1999. Mr. Lynch called our office and indicated that the Town experienced a
delay in acquiring correct statistical analyses from its certified biological laboratory for the
month of March 1999. Specifically, the Town's instream waste concentration decreased from
88% to 7% due to plant upgrade and although a multiple concentration toxicity test was
conducted during March, the Town's biological contract laboratory incorrectly assumed 88% to
be the correct permit limitation. Mr. Lynch faxed the requested AT-3 test form to our office
which reflects compliance with a 7% permit limit for March.
Mr. Lynch also inquired about correct toxicity testing months. Review of file
information indicates that a permit modification was issued to the Town on October 30, 1997,
which modified the Town's toxicity testing months from March, June, September, and December
(MJSD) to February, May, August, and November (FMAN). The Town has continued to test
for toxicity according to the MJSD schedule. Mr. Lynch was instructed to: conduct a toxicity
test during June 1999, notify the Town's biological laboratory that testing months should be j*
modified to FMAN, and begin toxicity testing per the FMAN schedule after June 1999.
The Town was informed that the March and April 1999 Discharge Monitoring Reports
were not received by the Division until June 1, 1999. Likewise, the office did not receive the
March 1999 toxicity self -monitoring data until June10. The Town was reminded that all self -
