Summary: The Town of Magnolia operates a 0.09 MGD wastewater treatment facility. The town
is requesting an expansion of the facility to 0.25 MGD. They have experienced III problems since
the late 90's. The town completed a rehabilitation project on a portion of their sewer system on
2001. This project helped reduce some of the Ill but did not eliminate the flow exceedances. During
periods of heavy rain the town continues to exceed the flow limit. The town is currently under a
sewer moratorium. They continue pursuing funding to rehabilitate the collection system.
The expansion request is to accommodate population growth, industrial flow, future residential
connections from unsewered areas and future commercial development on the 1-401SR 903
interchange. A flow of 0.250 MGD was justified to provide wastewater capacity for a 20 year
planning period. The town will construct a new treatment system and a discharge force main to
Stewarts Creek. They currently discharge to Millers Creek. Millers Creek is a zero flow stream,
therefore no expansions are allowed on this creek. The facility will also have a non-discharge
component with 10.9 acres for drip irrigation of up to 42,300 gpd. A Preliminary Engineering Report
and Engineering Alternatives Analysis was approved by the Construction Grants and Loans Section
on November 2004.
Facility Description: The existing facility consists of bar screen, grit removal, equalization basin,
extended aeration tank, dual clarifiers and chlorine disinfection. The proposed facility will include an
influent pump station, dual train aeration basins, dual clarifiers, aerated sludge digestion UV
disinfection, 33,000 linear feet effluent force main to Stewarts Creek, effluent pump station to
storage pond, irrigation pump station and a drip irrigation system on 10.9 acres to land apply up to
42,300 gpd. The existing equalization basin will be used with the new treatment system.

Basin Plan: Stewarts Creek is classified as supporting aquatic life because of good benthic
community. Stewarts Creek was previously included in the 303(d) list, but at this time the Division
is recommending its removal from the 303(d) list.
SUMMARY OF PROPOSED CHANGES
Proposed limits for a flow of 0.25 MGD are based on the speculative limits given to Magnolia on
1998 for the discharge to Stewarts Creek:
• BOD —5 mg/L (summer) / 10 mg/L (winter)
■ NH3N — 2 mg/L (summer) /4 mg/L (winter)
■ DO — 6 mg/L minimum
■ Fecal Coliform — 200/100 ml
• TRC— 17 pg/L

Hello, Teresa:
Thanks for contacting us about the Magnolia PER.
Larry has just forwarded me Mark McIntire's email
of Dec. 7, 2004, which indeed addressed the two concerns
that you have just asked: (1). 250K flow allowance and
(2) new discharge plan to Stewarts Creek.
Our Unit's flow calculation showed about 180K+ initially.
Then AE furnished us with their new info: a 400+-acre strip mall
complex was to be an imminent development in the I-40 intersection.
That's why the flow number was bumped up. McIntire was
surely aware of that. In fact, Dave Goodrich attended
a meeting with Bobby, Dan and AE at CG&L on 12-7-04'
in which the final deal (the 250k flow and Stewarts Creek discharge)
was hammered.
I hope that this explains to your question.
Please let know if you need further info.
Take care,
ZC

Bobby/Dan,
Won't be able to make it to the Magnolia meeting today but I did want to send you a
quick note regarding the PER we received in mid-November. You had two questions?
First, would the proposed 250K gpd discharge to Stewart's Creek be allowed. Second,
would the project require an EA? I think the 1998 sepculative limits letter is still
valid. I will say that the Town or their consultant needs to contact Curtis weaver at
USGS to obtain critical stream flow statistics (both 7Q10 and 30Q2 flows) . If both
are zero, we can't permit a discharge. If the 7Q10 is zero but the 30Q2 is positive,
we can proceed with 5 and 2 . We'll probably proceed with 5 and 2 even if both flows
are positive because of the difficulty modeling swamp systems. That being said, we'd

obviously prefer these folks go the land application/reuse route to the extent
practicable. With respect to SEPA requirements, T don't think they apply. With the
project below the SOOK threshold, no EA would be required. They should probably
contact Alex Marks in the Planning Section just to make absolutely sure.
Hope this helps.
Mark

Charles,
Thanks very much for the update.
Can you please let me know when it is assigned to a certain engineer, as we' ll
need to find out the approximate review time for new NPDES permit to be issued.
We've had several rounds of plans and specifications being modified over several
years, and we're about ready to issue permits and A-to-Cs, but (for whatever
reason) the Engineer - Hobbs, Upchurch & Associates - has been slow in getting
together the NPDES permit application. There was a meeting in our office way
back in Fall 2004 with Dave Goodrich and the Town of Magnolia, where Dave
essentually agreed in principle with the new NPDES permit and the new effluent
outfall at Stewarts Creek. The Town is very interested in getting this approved
and under construction ASAP.
Thanks!

well, i would agree that a nondischarage option would be hest. however, they only plan to
reuse 160,000 gpd and continue to dump 90,000 gpd into the receiving stream at it's end
point (it's a ditch that Mike W. has seen filled with sludge before)! The proposal is to build
a new plant to meet reuse standards (doesn't mean denitrication but would require tertiary
filters, UV...).
i think that i will present the stuff that you sent me to the contruction grants folks (they
want my review of the pelim. eng. report). personally, i think that HU&A should have
included adding the option to build a new plant and discharge to stewart's creek. by
comparison, wallace is permitted to discharge 1.0 MGD into stewart's creek in area area
that has less flow than at the (possible) magnolia discharge point.
thank you for helping nee with this one. ...jb

Jim - just faxed you back something. Apparently, we've been clown this road with them

even alter the 1998 letter). I think - for clown there, perhaps a non-discharge option may
be the best.

Speculative Discharge Limits
Town of Magnolia WWTP
Duplin County
Dear Mr.Buie:
Reference is made to the request submitted by you for speculative limits for the proposed relocation and expansion
(0.250 MGD)of discharge from the Town of Magnolia wastewater treatment plant(WWTP). We are hereby
supplying limits that would currently be assigned to the Magnolia WWTP if the discharge were relocated to one of
three sites (#2,#3, and#4)indicated on the attached map, which you submitted with the request. Because the
Magnolia WWTP currently discharges to a zero flow stream at site#I,expansion is prohibited at this location per
NCAC T15A: 02B .0206.
Limited flow information exists for the remaining proposed discharge locations,all of which are classified as swamp
waters. In some cases, low flow characteristics can be determined with significant statistical probability to have zero
values when drainage areas fall below a certain threshold. Sites#2 and#4 are located in hydrologic area 1 (HA1)as
defined in USGS Survey Water-Supply Paper 2403.(Low Flow Characteristics of Streants in North Carolina, 1993).
According to drainage area thresholds empirically determined for that area,the summer 7Q10 flows at each of these
sites is most likely zero, with a positive 30Q2 flow. According to NCAC T15A: 02B .0206 and Division policy,
new or expanded discharges to zero flow streams that have positive 30Q2 flows must be given the following limits:
Parameter ilimits Units Monthly Average)
BODE (Sum/Win) 5/10 mg/1
NH3N (Sum/Win) 2/4 mg/1
DO (Minimum) 6.0 mg/l
TSS 30 mgA
pH 6.0-9.0 SU
Fecal Coliform 200 /100 ml
Total Residual Chlorine (TRC) 17 µgA (Daily Max.)
Site#3 proposes discharge to Stewarts Creek and receives flow from a region designated as HA2. Based on a
significantly larger drainage area threshold for this area, as well as USGS gauging station flow data in the
vicinity of this site, this portion_ of Stewarts Creek is probably not a zero flow stream. Normally the
Division uses a Level B Model to determine appropriate limits for a discharge; however, this model does not
accurately predict impacts on swamp waters. Because of the uncertainty associated with such a slow-moving,
swampy system, the limits listed above for sites#2 and #4 would apply to site#3 at a flow of 0.250 MGD,
in order to maintain BOD mass loading as close to the current value as possible.

Under current DWQ procedure,dechlorination and chlorine limits are now required for all new or expanding
dischargers proposing the use of chlorine for disinfection. The level of residual chlorine in the effluent
necessary to ensure against acute toxicity is given above. The process of chlorination in combination with
dechlorination or an alternate form of disinfection, such as ultraviolet radiation (UV disinfection), should
allow the facility to comply with the TRC limit.
North Carolina General Statutes require implementation of the practicable waste treatment and disposal
alternative with the least adverse impact on the environment. Non-discharge alternatives are considered to be
environmentally preferable to discharge. In order to receive final permit limits,a formal application
indicating the proposed WWTP design capacity'and justification for the facility's relocation of direct discharge
will have to be submitted to the NPDES Unit.
The application must include an Engineering Alternatives Analysis (EAA)detailing investigation of
alternatives to surface water discharge(please refer to the enclosed EAA Guidance Document). It has come to
the Division's attention that the Town of Magnolia is requesting funding from the Clean Water Management
Trust Fund (CWMTF) for construction of a new wastewater land application system. The Division is also
aware of the possibility of connection to the Town of Rose Hill. In addition to any other possible
alternatives,these items must be addressed thoroughly as part of the submitted alternatives analysis,should
the Town of Magnolia choose to pursue an NPDES permit for direct discharge.
Please be advised that the response to a speculative request does=guarantee that the Division will issue an
NPDES permit to discharge treated wastewater. It should be noted that a new facility involving the
expenditure of public funds or use of public(state)lands and having a design capacity of 0.5 MGD or greater
(or proposing an expansion of 0.5 MGD or greater),or exceeding one-third of the 7Q10 of the receiving
stream(as in this case)will require the preparation of an environmental assessment(EA)by the applicant.
DWQ will not accept a permit application for a project requiring an EA until the document has been approved
by the Department of Environment and Natural Resources,and a Finding of No Significant Impact(FONSI)
has been sent to the State Clearinghouse for review and comment. The EA should contain a clear
justification for the proposed facility and an analysis of potential alternatives, which should include a
thorough evaluation of non-discharge alternatives(this satisfies the EAA requirement). In addition,an EA
should show how water reuse,conservation,and inflow/infiltration reductions have been considered. If the
EA demonstrates that the project may result in a significant adverse effect on the quality of the environment,
an Environmental Impact Statement(EIS)would be required.
If you have any questions regarding these speculative limits,please contact Bethany Bolt at(919) 733-5083,
Ext. 551.

David A. Goodrich,

Wastewater Treatment Plant Upgrade & Effluent Reuse
Project No. E-SRG-T-02-0130
One copy of the subject Preliminary Engineering Report, which has been revised to include the
relocation of the WWTP discharge to Stewart's Creek, is attached for your reference. In our
July 6 comments (copy attached for reference), Construction Grants and Loans Section (CG&L)
requested the town and their consultant to consider relocating the discharge (see comment III, 2)
and Dan Blaisdell and Bobby Blowe met with you on July 28 to discuss the discharge relocation.
The NPDES Unit provided speculative limits for the proposed discharge point in an
April 20, 1998 letter. Your input concerning the proposed work and the following questions
would be greatly appreciated:
• Would the proposed 250,000-gpd discharge at Stewarts Creek still be allowed, and
would the speculative limits be the same as discussed in the April 20, 1998 letter?
■ Since this would be a relocation of an existing discharge and the expansion from
90,000 to 250,000 gpd is less than an additional 500,000 gpd, CG&L does not believe
that a FNSI/EA would be needed for this project or the NPDES Permit changes. Does
the NPDES Unit concur?

Technical Review Comments
Preliminary Engineering Report
Wastewater Treatment Plant Upgrade
Project No. E-SRG-T-02-0130
July 6, 2004
I. General
1. Please note that approval of the PER does not constitute approval of sole source
procurement. Plans and specifications must comply with N.C. General Statute
Chapter 133, Section 3, prior to their approval.
2. The owner and consulting engineer should be advised that after approval of the PER,
there are several constriction project permits, approvals, certifications, etc. that must be
obtained before the project plans and specifications can be approved, and before the
project is advertised for bids. Therefore, it is strongly recommended that preliminary
work to obtain the following items, if applicable, begin as soon as possible:
a) Sedimentation and Erosion Control Permit from the Division of Land Quality,
or a letter from them stating that no permit is required for this project;
b) 401 Water Quality Certification and Army Corps of Engineers 404 Permit for
all stream crossings, or a letter from the Army Corps of Engineers and from
the Wetlands 401 Certification Unit stating that none is required for this
project;
c) A reasonable subsurface investigation must be made available to the
contractor. if it is not included in the specifications, the specifications must
advise where a copy of the report can be observed. Typically, Construction
Grants and Loans expects a boring about every 500 feet and at each road
crossing for line work, and at all major structures like pump stations,
aeration basins, and clarifiers;
d) NCDOT Encroachment Agreements and Railroad Encroachment Agreements.
Copies of these agreements must be provided in the specifications, or it must
be documented how all construction requirements, associated with the
agreements, have been incorporated in the plans-,
d) Section 10 Permit for aerial crossings of navigable waters, or a letter from
the Corps stating that none is required for this project;
f) All construction easements, permanent easements, and rights-of-way. These
easements and rights-of-way must be shown on the plans.

3. Does the town of Magnolia intend to make connection to the sewer system
mandatory? In order to maximize the public health and environmental benefits of the
project, it is strongly recommended that connection to the sewer system be mandatory.
II. 2.0 Proiect.Planning Area
1. Page 5: Please use the North Carolina Office of State Planning (OSPL) Duplin County
incremental population growth rates for projecting the town of Magnolia's design-year
population. Using this method, the OSPL Duplin County population growth rates were
calculated as follows:
OSPL Duplin County 2000-2010 2010-2020 2020-2030
Population growth rate: 14.3% 1 1.8% 9.9%
Year 2000 2005 2010 2020 2025 2030
Magnolia population: 932 1,065 1,191 1,309
Population Interpolated: 999 1,250
2. Page 5: Provide narrative in the PER to discuss how the 4,373 gpd industrial reserve
was determined. Future industrial flows that are justifiable based on a Letter of Intent
are allowed. Also, an industrial reserve that is 10% of current flow, excluding 1/1, is
allowable.
3. Pages 5-6: Flow projected from the currently un-sewered area is 17,280 gpd from 48
houses. Provide some narrative in the PER to discuss how the 17,280 gpd was
calculated.
4. Provide information concerning the sludge treatment and disposal for the proposed new
WWTP that addresses how sludge management will comply with the 40 CFR 503
Regulations, including the following:
a) ' Sludge production calculations at the design flow and a discussion of the methods
that will be used to comply with pathogen and vector attraction reduction.
b) Discuss the adequacy of the ultimate sludge disposal sites) at the design flow for the
20-year planning period.
c) Confirmation of an agreement(s) with owner(s) of permitted sludge sites, or a
modifiable permit held by a contract hauler.
5. Confirm that the proposed project design will comply with NCAC 2H.0219 - Minimum
Design Requirements, and NCAC 2H.0124 - Reliability Requirements. (A copy of
.0219 & .0124 is attached for reference).

[II. 3.0 Alternatives Analysis
1. Page 10 and Appendix H, Figure G-4: The report indicates that the aeration basins will
be followed by either dual clarifiers (conventional operation) or dual equalization
basins (sequential operation). Please provide additional information concerning the
need for and the effectiveness of using equalization basins to provide to the function
normally provided by clarifiers.
2. Pages 7-13: The Wilmington Regional Office (WiRO) has commented on the PER and
their comments are attached for reference. Based on the WiRO observations and the
CG&L review, it appears that the alternative chosen, which is the construction of a
0.250 MGD tertiary package plant with 146,750 gpd drip irrigation and 90,000 gpd
surface discharge to the existing zero-flow stream, may not be the most
environmentally beneficial option, and it may not be the most cost-effective alternative.
Speculative limits were requested and were provided for three alternate discharge sites
in DWQ's April 20, 1998 letter. One of the three discharge sites is at_Stewart's Creek,
and DWQ noted that Stewart's Creek is probably not a zero-flow stream at the
discharge location where speculative limits were provided. Please contact the NPDES
Unit of the Water Quality Section Division and confirm whether or not an NPDES
Permit can be issued for a discharge to Stewart's Creek at NCSR 1104. If an NPDES
Permit can be issued, the PER should include a present worth analysis of an alternative
that consists of a 0.250 MGD WWTP with a surface discharge of 0.250 MGD at
Stewart's Creek and a 147,000 gpd drip irrigation disposal. The additional cost of a
pump station and force main to send the effluent to Stewart's Creek should be offset
somewhat or completely by the elimination of the need for the 60-day reclaimed water
storage pond.
3. Page 11, Appendix H: Please confirm whether or not items 67, 68, and 69 include the
costs of both the 12-day upset pond and the 60-day storage pond (i.e. approximately
10,584,000 gallons). If so, the estimated $0.03 cost-per-gallon of storage seems low.
4. Page 11: The PER indicates the desire to bid the Re-Cip system as an alternate. At this
time, the Re-Cip system is not shown to be the most cost-effective alternative, and
therefore world not be eligible for grant/loan participation. Only if it can be shown that
the Re-Cip system can consistently meet reclaimed water standards (see comment 5
below), it may be bid as an alternate. However, if that is the case and both systems are
proposed for bidding, then a detailed set of plans and specifications for both the "
selected alternative and for the Re-Cip must be prepared and submitted to CG&L for
review, and they must be approved prior to the bidding process.
5. BioConcepts, Inc. provided information concerning the Re-Cip system performance to
Constriction Grants & Loans in July 2003. This information does not support a
determination that the Re-Cip system can consistently meet the reuse effluent quality
requirements of NCAC 2H.0219, (k). The reuse effluent quality standards are as
follows:
Page 3 of 4

Reuse standards require the treatment process to produce a tertiary quality effluent in
accordance with the following limitations:
• Monthly average TSS < 5 mg/I with a daily maximum 5 10 mg/I
+ Monthly Mean Iwecal-Coliform.S-14/100 m1 with a daily-maximum <_ 25/100 ml
• Monthly Average B01)5 S 10 mg/I with a daily maximum 5 15 mg/I
* Monthly Average NH3 <4 mg/l with a daily maximum <_ G mg/I
• Instantaneous Daily Maximum Turbidity_< 10 NTU's
Before the Re-Cip system can be determined adequate to consistently meet the reuse
effluent quality requirements, additional supporting information must be submitted that
will support this determination. If available, conclusive evidence based on a year of
sampling data, which preferably includes 2 samples per week or daily samples from
one or more Re-Cip systems that are currently treating domestic waste in a climate
similar to the town of Magnolia should be submitted. At a minimum, the most recent
Re-Cip related performance data should be incorporated into a revised PER.
6. Page 12: In order to determine which alternative is the most cost-effective in the 20-
year period of time, please include detailed present worth analyses for all alternatives
discussed in the PER. The present worth analysis should include the following items:
a) Capital costs including the costs associated with patent fees.
b) Contingency.
c) Costs for engineering.
d) Start-up services, if applicable.
e) Operation & Maintenance manual.
f) Land and easements, etc. Itemize these costs and include them in the present
worth analysis.
g) Annual operation and maintenance costs and present worth of those costs.
h) Present worth of replacement costs.
i) Present worth of salvage value.
7. Pages 1 1-12: Show what EPA discount rate was used in the PER to calculate the
"present value", and how the total present worth factor is derived.
8. In determining the present worth of an alternative's salvage value, a useful life of 15
years for equipment, 40 years for collector sewers, 20 years for pump stations and.force
mains, 50 years for structures, and 20 years for all other facilities should be used for the
salvage value present worth calculations.
9. The present worth of operation and maintenance costs should be calculated based on a
constant annual cost without any annual cost increases.

Subject : Town of Magnolia
Preliminary Engineering Report Review
NPDES Permit No . NC0020346
CG&L Project No . E-SRG-T-02-0130
Duplin County
The writer has reviewed the subject report , prepared by Hobbs
Upchurch & Assoc . , for the Town of Magnolia . A records review was
conducted, but a site review was not performed.
Division records indicate that the Town needs the ability to treat
more than the current 90 , 000 gpd permitted discharge volume .
Division monitoring reports covering nine months of operation over
the period of February 2003 to January 2004 (10/03 , 11/03 & 12/03
missing) were evaluated. The DMR data showed that. 2/03 was the
lowest flow month with average monthly, maximum monthly, and
minimum monthly influent flows of . 077 MGD, . 123 MGD, and . 043 MGD,
respectively. The maximum flow month was 8/03 with . 114 MGD
average, . 161 MGD maximum and . 050 MGD minimum. Influent flow
records for 2/03 and 8/03 and rainfall data from the National
Weather Service-Wilmington are enclosed for your convenience.
Magnolia is located approximately 50 miles north of Wilmington.
The collection system is experiencing substantial inflow and
infiltration. In the lowest flow month, 48 hours were needed after
the 2/16/03 inclement weather event for flows to return to normal .
There were no obvious flow/rainfall trends occurring in 8/03 .
Scattered thunderstorms normally prevail in the summer, and it is
likely that Wilmington rainfall volumes may not have similarity to
rainfall at Magnolia during the summer. Additional actions to
correct inflow/infiltration are recommended.

The option chosen, construction of a . 250 MGD tertiary treatment
plant with 146, 750 MGD spray irrigation reuse and 90, 000 GPD NPDES
discharge to the existing zero-flow stream, may not be the most
environmentally friendly option. It also may not be the most cost
effective option for increasing the design flow of the Town of
Magnolia wastewater treatment plant . The consultant has not
evaluated extending the effluent line (approx. 5 miles west) to
Stewarts Creek. The Town of Warsaw is permitted to discharge 1 . 0
MGD into Stewart' s Creek at an (upstream) point that has less
stream flow volume, by comparison. The consultants requested NPDES
permitting speculative limits for the Town of Magnolia in 1998 . The
Division' s reply is enclosed for your convenience . Discharge point
##3 is located where NCSR 1104 passes over Stewarts Creek and
likely has a positive 7Q10 flow. A recent aerial photograph of
Stewarts Creek at NCSR 1104 is enclosed.
It is understood that irrigation reuse is mandated for achieving
qualification for a 3 000 000 high-unit cost rant . The proposed
q $ g g P P
dual train activated sludge extended aeration tertiary filtration
plant would provide better quality effluent , but there is an
alternative discharge point that should be considered. Although,
the Town does maintain the 90, 000 gpd NPDES permit, the outfall is
located at a source of a zero flow stream (the driest part of the
zero flow stream) . The Clean Water Management grant should be
initiated to increase the Town' s permitted wastewater flow while
removing the current discharge . The writer would recommend that the
Stewarts Creek discharge option coupled with a nondischarge
proposal be explored primarily to remove the existing NPDES
discharge while qualifying for the construction grant . The first
step toward exploring the alternate discharge- point would be for
the consultant to verify with USGS that Stewart ' s Creek at NCSR
1104 does not exhibit a zero 7Q10 flow.
The writer does not have experience with the proposed recip
treatment option. It has been determined to exceed the cost of the
activated sludge plant and the recip treatment system would capture
more rainfall input . Based upon the above, the activated sludge
extended aeration plant would be recommended.

DearMr.Buie. � '

(0150 IAGP) of discharge from the Town of MzpoUa wmewate r ttx=ent plant(WRti�?). We eat hereby
supplying limits that would;ca=dy be assigned to the I&palia WVt TP if the discharge wve.rziacated-to one of
three sitr ttaahod s($2,#3,and#4)indicated on the i mV,which you subatirmd with tbi:toquesL Beewse the

NCAC T1SA' 02B .020b,
Lia ited flow information eicists for the runaining proposed discharge locations,all of which are classified m swamp
waters. In some cases,low1low clu uutistics can be detcrminM with significant stadstics)probabiLry to have zero
values when dt bage areas fall below a ctstain threshold Sites#2 and#4 am I mated in hydrologic area 1 (RAI)as
defined in USGS Survey V ==•Supply Paper 2403.(Ld7w Flow Characteristics of Streams in North Carolina. 1993).
According to drainage ores Outesboldr,tmpirically deuxmiacd tot that area,the sutamcr 1Q10 flows at mach of them
siras is most likely zero,with a positive 3DQ2 flow. A cording to NCAC TI SA: 023 .0206 and Divixion policy,'
new ar expanded discbarges to zero flow streams that!save positive 30QZ flaws must be given the following limits:

sigtdficamly larger ch-ainagc area ftubold for this ams, as well as USGS gauging station flow duo is the
vicinity of this site,this p mon of Stewuts Cr=k is ptvbably trot a zero flour:stream Normally the
Division uses a Level B Model to determine appropriate limits for a discharge;however,this model dots not
acct>tate)y prec itt impacts on swamp waien. Because of the uncertainty associated%rich soeb a slow-moving,
swampy system,the limits listed above for sates 42 And#4 would apply to site#3 at a flow of 0250 MGD,
in order to maintain HOD mass loading as close to the current value as possible.
