A. (3) 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 15%. .
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 11 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 THP313 for the Chronic Value. Additionally, DWQ
Form AT-3 (original) is to be sent to the following address:
Attention: NC DENR / DWQ / Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 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, 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 Section 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.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of
such monitoring'shall be included in the calculation and reporting of the data submitted on the DMR
and all AT Forms submitted.

Background
The U.S. military, through a process called "Base Realignment and Closure,'
or BRAC is in the process of transforming the Fort Bragg and Pope AFB areas
by moving thousands of military personnel, dependents, and contractors to
the area. Many of these will be relocated into the South Harnett County
Regional Wastewater Treatment Plant service area, allowing other military
bases to be closed. In order to efficiently provide infrastructure to keep up
with the growth, the U.S. military, NC Department of Environment and
Natural Resources (DENR), the Division of Water Quality (DWQ), and Harnett
County government have worked together to develop plans for providing
wastewater treatment facilities. Harnett County currently operates a 5.0
MGD regional WWTP near Fort Bragg and Spring Lake. The facility appears
to have started up in June, 2009, and is discharging less than 1 MGD so far.
Fort Bragg operates an 8.0 MGD WWTP that is old and has operational
problems due to the facility age. The town of Spring Lake operates a 1.5
MGD WWTP that is also old and having operational problems. Harnett
County proposes to expand the South Harnett Regional WWTP to 15.0 MGD
with a tertiary treatment facility, taking flow from Fort Bragg and Spring
Lake, and retiring the two older facilities.
Fact Sheet
NPDCS NCO088366 Draft
Page I

Harnett County has produced an Engineering Assessment (EA) for this
expansion, which has undergone a North Carolina Environmental Policy Act
review, leading to the issuance of a Finding of No Significant Impact (FONSI)
on October 27, 2009 allowing the project to proceed.
Receiving Water Review
This facility discharges to Lower Little River near the town of Spring Lake.
Lower Little River is classified as C waters in the Cape Fear River Basin, and
is listed as Impaired for pH on the 2006 EPA approved 303(d) list. DWQ is
continuing to monitor water quality in Lower Little River to try and determine
the source of impairment. It may be local drought related. Little River drains
into the Middle Cape Fear River between Buckhorn dam and Lock and Dam
Number Three, which is impaired for chlorophyll A in the four miles upstream
of the lock and dam.
SEPA Review
Pursuant to the requirements of the North Carolina Environmental Policy Act
(N.C.G.S. § 113A-1, etseq.), an environmental assessment (EA) was prepared
by Harnett County for the wastewater treatment facilities proposed
expansion.
Five alternatives were considered for the wastewater treatment facility for
Harnett County: Connect to an existing WWTP, Land Application of 10 MGD,
Reclaimed Water Application of 10 MGD, a point source discharge
alternative, and a combination of alternatives.
Alternate 1.1 would keep the Fort Bragg and Spring Lake WWTPs in
operation. In order to protect instream dissolved oxygen (DO), both plants
would have to be extensively upgraded to tertiary treatment standards with
5/1 mg/L limits for BOD and Ammonia -Nitrogen. This is because in 2002 an
engineer running a Level B model determined that the Lower Little River had
been overallocated for oxygen consuming wastes. The Department of
Defense has determined that it is not economically feasible to upgrade the
Fort Bragg WWTP, and has entered into a long term agreement with Harnett
County to treat Fort Bragg's wastewater. This option was considered "not
technologically feasible.,,
Alternate 1.2 considered shutting down the Fort Bragg and Spring Lake
WWTPs and pumping the wastewater to Fayetteville's Cross Creek WWTP.
This scenario is not feasible as Cross Creek does not have sufficient
unallocated capacity to treat the new flow. This option was also considered
"not technologically feasible.,,
Alternate 2 considers land application of 10 MGD from Fort Bragg and Spring
Lake, while discharging 5 MGD from Harnett County's facility. The soils
present in Southern Harnett and Northern Cumberland County are not
amenable to spray irrigation. Approximately 7,000 acres would be required;
there is no such tract available. This alternative is considered "cost
prohibitive."
Fact Sheet
NPDES NCO088366 Draft
Page 2

Alternative 3 considers reclaimed water application. It considers pumping 10
MGD reclaimed water treated to tertiary levels to facilities such as golf
courses or turf farms. There are no industries or potential customers for this
amount of recycled water. This option was also considered "not
technologically feasible."
Alternative 4 considers expanding the existing 5.0 MGD South Harnett
County Regional WWTP to 15.0 MGD capacity, taking the flow from Fort
Bragg and Spring Lake, treating all the wastewater to tertiary standards and
discharging to the Lower Little River and decommissioning the two older
plants. This option is the preferred course.
Alternative 5 considers a combination of alternatives 1 through 4.
Alternatives 1 through 3 were all dismissed as either "not technologically
feasible" or "cost prohibitive." No combination of there alternates could be
determined to be better than the expansion and direct discharge alternative.
Based on the findings of the EA, the impact avoidance/mitigation measures
contained therein, and reviewed by governmental agencies, the Division of
Water Quality has concluded that the proposed project will not result in
significant impacts to the environment. The EA and Finding of No Significant
Impact (FONSI) are prerequisites for the issuance of Division of Water Quality
permits necessary for the project's construction.
Permitting Strategy
The wastewater treatment system is to be an advanced tertiary facility with
three 5.0 MGD modules. Disinfection will be by ultraviolet light (UV) instead
of chlorine. The treatment system will be designed to comply with very
stringent limits of 1.0 mg/ L of ammonia nitrogen and 5.0 mg/ L of BODS in
keeping with the Basinwide Quality Plan for new and expanding POTWs.
Nutrients
In keeping with the Basinwide Quality Plan, seasonal mass based limits are
placed equivalent to 6.0 mg/ L TN and 2.0 mg/ L TP for the time period of
April through October. at the permitted flow of 15.0 MGD.
Reasonable Potential Analysis (RPA)
The facility has only been in operation for less than 6 months, operating at
very low flowrates. No DMRs were reviewed for this permit modification, so
no RPA was conducted.
Proposed Schedule For Permit Issuance
Draft Permit to Public Notice: February 17, 2010.
Permit Scheduled to Issue: April, 2010.
Permit effective date: May 1, 2010
Expiration Date: May 31, 2011
Note: The expiration date has been changed to May 31, 2011, in order to
comply with the basinwide schedule.

Harnett County — Proposed South Regional WWTP
Harnett County (HCO) is proposing to build a Regional WWTP discharging to the Little River near
Spring Lake to service the southern portion of HCO. They are connecting the Cooper's Ranch WWTP
(0.04 MGD) and possibly Fort Bragg (8.0 MGD) and Spring Lake (1.5 MGD). Fort Bragg has agreed to
sell their utilities to HCO. Spring Lake has not agreed to tie into the new plant.
November 26, 2002 — Speculative Limits letter from DWQ to HCO. The request was for discharges of
2.5 and 5.0 MGD to the Little River. Modeling showed that the stream is over -allocated for oxygen
consuming wastes. The 2.5 MGD discharge is not possible under current conditions. If they connect
Spring Lake, oxygen levels are acceptable. Gave them spec limits for 5.0 MGD if they connected
Spring Lake.
February 11, 2004 —Speculative Limits letter from DWQ to HCO for a 15.0 MGD at the Little River,
connecting both Spring Lake and Fort Bragg.
March 29, 2005 — Harnett Co. submitted a permit application for the South Regional WWTP. The
proposed project was for a 3.5 MGD WWTP on the Little River but did not include the connection of
Spring Lake to their system. The FONSI included with the application was not for the Regional
WWTP, it was for a collection system project. The application request was return to HCO on April 29,
2005.
May 13, 2005 — Meeting with Teresa Rodriguez & Mark McIntire (DWQ) and Hiram Marziano
(engineer for HCO) and Rodney Tart (HCO). They want to move ahead with the regional facility, but
don't know if Fort Bragg and Spring Lake will be connecting to the plant. Discussed the need to run a
new model for the proposal. They will look at running a QUAL2E model.
July 26, 2005 — Meeting with Teresa Rodriguez, Gil Vinzani, Jackie Nowel (DWQ) and Hiram
Marziano & Rodney Tart (HCO). Discussed QUAL2K model. Proposed location for the discharge was
moved farther downstream. Discussed FONSI from USDA, is not applicable to this project. Discussed
the need for an EA.
September 8, 2005 — HCO submits QUAL2K model for the proposed WWTP on the Little River.
Adugna Kebede from the Modeling/TMDL Unit reviewed the model. The model shows that the
dissolved oxygen in the river is maintained above the water quality standard.
November 3, 2005 — Meeting with Teresa Rodriguez & Gil Vinzani (DWQ), and Rodney Tart &
Hiram Marziano (HCO). HCO presented an Engineering Report for the proposed project. The report
covered a separate project for a sewer collection system.
November 10, 2005 — Meeting with Alex Marks, Melba McGee, Teresa Rodriguez (DWQ) and Hiram
Marziano (HCO). Discussed the need for Harnett County to submit an EA for the proposed project.
March 5, 2006 — HCO submits a preliminary EA document for completeness review.
April 24, 2006 — HCO submits EA for a 5.0 MGD Regional WWTP on the Little River. It does not
include the flow from Fort Bragg. Negotiations with Fort Bragg are ongoing.
June 7, 2006 — DWQ sent HCO comment letter on EA.
July 26, 2006 — Received response to EA comments from HCO.

RE: South Harnett Regional WWTP
NPDES Permit Application to Upgrade Discharge from 5 mgd to 15 mgd
Harnett County Department of Public Utilities
M&M Project No.: 26015
Dear Sir/Madam:
Enclosed please find the following information submitted for the above referenced project:
• A check in the amount of $1030
• Three (3) copies of the application EPA Form-2A
• Three (3) copies of EAA with supporting documents, including the following:
o Finding of No Significant Impact (FONSI issued 10-27-09)
o ATC for the South Harnett WWTP Upgrade to 15 mgd (issued 12-4-2009)
Harnett County is in the process of constructing upgrades to the South Harnett Regional
WWTP to serve Fort Bragg and the Town of Spring Lake. This NPDES permit application
requests an increase from the current NPDES Discharge permit of 5 mgd to the new 15 mgd
capacity of the WWTP. All wastewater will be discharged to the Lower Little River (existing
discharge location 001) in Harnett County. The existing wastewater treatment facility at Fort
Bragg will be decommissioned as a result of this project. In the future, it is anticipated that the
existing wastewater treatment facility at Spring Lake will be decommissioned as a result of this
project. A SEPA environmental assessment was prepared on behalf of Harnett County and
received a Finding of No Significant Impact on 10-27-09 (SCH 10-E-4300-0113). A copy of the
FONSI is included in the EAA, Appendix A.
An ATC was issued for the proposed WWTP expansion on 12-4-09 (ATC 088366-A02, see EAA,
Appendix A). The expansion of the WWTP will include the following items: construction of two
5 mgd Intermittent Cycle Extended Aeration System (ICEAS) trains, including piping,
decanting, fine bubble diffusion and blowers, construction of two 5 mgd traveling bridge tertiary
filters including backwash pumping, piping, installation of additional UV disinfection modules
which would allow up to a peak flow of 42.5 mgd with one bank of UV modules out of service.
Modifications to the existing handling system include the installation of a bioset sludge
pasteurization system and all necessary site work piping and electrical. The existing headworks
and cascade aeration discharge system are adequate for the 15 mgd flow rate peaking at 42.5 mgd.
