Dear Mr. Anderson:
Division personnel have reviewed and approved your application for 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 October 15, 2007 (or as
subsequently amended).
The revisions stated in the Division's August 22, 2009 response letter have been incorporated. After
further review by the Division, the Arsenic and Total Chromium limits are defined as a daily maximum and
a monthly average. Both the daily maximum and monthly average limits are required to meet EPA
mandates.
Summary of Requirements
1) A Flow Monthly Average Limit is required. Effluent flow is limited and as such its compliance is
determined by a monthly average.
2) Total Suspended Solids Limits are required. Total Suspended Solids is a primary pollutant and as
such its compliance is determined by both a daily maximum limit and monthly average limit.
3) A pH Limit Range is required. The pH is a primary parameter and as such a compliance range is
defined.
4) Ammonia as Nitrogen Limits are required. Ammonia is a pollutant and toxicant of concern and as
such its compliance is determined by both a daily maximum and monthly average.
5) Arsenic and Total Chromium Limits are required. Evaluation of the data submitted yielded Arsenic
and Total Chromium exceeding water quality standards (WQS). Compliance limits are defined by
both a daily maximum and monthly average as stipulated by the EPA.
6) Total Copper, Total Silver, and Total Zinc monitoring are required. Total Copper, Total Silver, and
Total Zinc are toxicants of concern and as such monitoring in conjunction with the Chronic Toxicity
Test is required.

7) An Acute Toxicity Pass/Fad Limit is required. Effluent toxicity is a primary factor and is used! to
evaluate the toxicity and/or define a base line for the impact of this effluent on WQS. The test
sample must be taken in conjunction with sampling for the other permit effluent characteristics.
8) A Special Condition A.(3.) is required for future effluent characterization. At the discretion of the
Division other chemical and/or property analysis can be requested. The results may result in the
permit being reopened and additional requirements being added.
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)

BACKGROUND
Pharmaceutical Products Development, Inc. (PPD) office building is located on a 7.48 acre
tract formerly used as a chemical terminal by Almont Shipping. A parking garage and other
ground level structures are located on the site. Isolating the shallow water table from the
structure was part of the original design. However, seepage is occurring.
Initially, a dewatering system to capture and divert the seepage was installed. The discharge
was permitted as an Industrial User Permit by the City of Wilmington POTW. The last permit
issued in June 2008 by the City of Wilmington was issued with the understanding that this
option was short term and at some point in the future this discharge would not be accepted.
PPD is expected to pursue alternative disposal methods.
Depending on rain events 8,000 gpd to 10,500 gpd of recovered groundwater is discharged
to the POTW. Analysis of the ground water yielded high levels of ammonia and arsenic.
PPD has submitted a NPDES application for a surface discharge of treated wastewater from a
packaged treatment plant designed for the dewatering activity. The discharge will be
introduced to a local storm drain which discharges to the Northeast Cape Fear River
approximately 1,000 feet from the site.
EAA
As required by the NPDES application process an EAA was conducted. The preferred option,
using the local POTW, long term is not available so other options were investigated.
p Land application/reuse - Current property is premium commercial acreage. Additional
storage would be required. Capital cost $828,000 with 20 year present value worth of
$5,778,306.
p Seasonal irrigation - Currently PPD purchases water from the City of Wilmington for
landscape irrigation. However, will still need to treat before reuse and will need surface
discharge when irrigation is not available.
The Divisions agrees that the recommended method would be to continue to utilize the
POTW. But in the absence of the POTW accepting the discharge the Division has no objection
to a permitted NPDES surface discharge of treated wastewater. The Division would
encourage PPD to revisit reusing the treated wastewater for irrigation.

WASTEWATER TREATMENT/SURFACE WATER DISCHARGE
Wells will be used to extract ground water from around the existing structure and minimize
seepage. The collected groundwater will be treated by a custom package ion exchange
system to reduce the ammonia and arsenic to acceptable levels equivalent to water quality
standards. A pH adjustment system is also included. As the ion system becomes spent, a
contract service will install new units and remove the spent units. The contract service will
be responsible for disposal of the spent units. A disposable cartridge pre -filter is also
included.
The design flow for the system is 2 gpm to 20 gpm with 10 gpm being optimum. For
permitting purposes 20 gpm was used to define the permitted flow, 0.029 MGD.
The treated groundwater will discharge to a local storm water drain (as approved by the City
of Wilmington) and continue to the Northeast Cape Fear River.
PERMITTING STRATEGY
Submitted well data was compared to Water Quality Standards and Effluent Guidelines. TSS,
ammonia, arsenic, chromium, and pH were identified as pollutants of concern requiring
limits. Per Division policy, for a tidal receiving stream, ammonia limits were established for
summer and winter conditions with monthly and daily average limits. Arsenic and chromium
limits were required to meet chronic SC WQS, a weekly monthly average. To comply with
EPA guidelines an arsenic and chromium FneFithly aveFage daily maximum limit were
defined. TSS was limited to meet Effluent Guidelines and included daily and monthly average
limits. pH was limited by a range for SC waters.
A quarterly Acute Pass/Fail Toxicity Limit test (WET test) was required to define the impact
of the treated discharge. Additional monitoring for action level toxicants copper, silver, and
zinc was also required in conjunction with the WET test.
Because of the potential for other pollutants to emerge as the ground water is extracted, a
Special Condition for request by the Division for additional analysis and reopening of the
permit was added. Because of the less than 30,000 gpm flow all samples may be grab
samples. The portion of the Cape Fear is not listed as a NSW so no additional TN or TP
monitoring is required. Oil and grease are addressed in the narrative

Ron,
You and I already spoke about this one. If the City of Wilmington does not want to accommodate them, they don't
really have any other alternatives that I can see besides direct discharge. I hoped the City would continue to take this
wastewater since they have not seemed to have any problems at their plant treating this waste. The City is the BEST
alternative to direct discharge. The system PPD proposes will have some reliability issues associated with it, but I
suppose that can be handled through the A to C process with CG&L. WiRO will not object to a direct discharge to the
Northeast Cape Fear River.

Dear Mr. Vinzani,
AECOM North Carolina, Inc. (AECOM) is submitting the enclosed application for a National Pollution
Discharge Elimination System (NPDES) permit on behalf of Pharmaceutical Product Development, Inc.
(PPD). This application package includes Short Form C-GW and an Engineering Alternatives Analysis.
PPD recently completed construction of a building located at 929 North Front Street in Wilmington,
North Carolina. Following construction, groundwater has been observed to seep into the lower parking
deck and adjacent courtyard, preventing full and complete use of the facility and has also prevented
PPD from receiving a final Certificate of Occupancy for the site. Currently, PPD is discharging
recovered water from these areas to the City's sanitary sewer system, under an approved Industrial
User Permit (IUP). Direct discharge of extracted groundwater under the IUP is currently the most cost
effective and has the least potential for environmental impact. However, the IUP permit was issued with
the condition that PPD investigate an alternate disposal method for the groundwater. AECOM evaluated
alternative disposal methods and concluded that a direct discharge to the Cape Fear River is the most
economically feasible alternative, assuming continued discharge via an IUP is not possible.
On June 12, 2008, AECOM and PPD representatives participated in a meeting with your staff to discuss
the proposed project and permitting requirements. This application and Engineering Alternatives
Analysis were developed according to the Division of Water Quality guidance. If you have any questions
or need additional information please contact Teresa Rodriguez at 919-872-6600, ext. 279 or Peter

1.0 Introduction
AECOM North Carolina (AECOM) has prepared this Engineering Alternatives Analysis on behalf of
Pharmaceutical Product Development, Inc. (PPD) to support the National Pollutant Discharge Elimination
System (NPDES) permit application for a new groundwater treatment discharge into the Northeast Cape Fear
River. PPD recently constructed a new office building located at 929 North Front Street in Wilmington, North
Carolina (the Site). The building was constructed in an area with a relatively shallow water table.
Subsequently, the building has experienced groundwater seepage into the lower parking deck and adjacent
courtyard. This Engineering Alternatives Analysis is being submitted to support the NPDES permit application
to discharge treated groundwater to the Northeast Cape Fear River. Both the City of Wilmington and New
Hanover County have certified that the project adheres to local zoning ordinances. Local Government Review
Forms are included in Appendix A.
1.1 Site description
The PPD building occupies a 7.48 acre site delineated by Harnett Street on the north, North Front Street on
the east, Brunswick Street on the south and a property owned by Almont Shipping Company on the east. A
topographic map showing the Site location is included as Figure 1. The Site is located in an area that was
previously used as a shipping and storage operation for fertilizers and salts.
The initial design of the building considered the shallow water table and efforts were made to design the floor
of the parking structure above the water table or to add a sealant/barrier in the building sub -grade material to
avoid influx of groundwater into the building. Ultimately, this approach was not effective at preventing the
11A� seepage of groundwater into the lower parking level of the garage or the adjacent courtyard.
PPD obtained an Industrial User Permit (IUP), Permit No. N132, from the City of Wilmington to discharge the
groundwater and stormwater runoff that accumulates in the parking lot and courtyard to the James A. Loughlin
Wastewater Treatment Plant (WWTP). The most recent permit was issued in June 2008 with the
understanding that this method of disposal was for a short-term period and PPD would pursue other treatment
and disposal alternatives. Water seepage into the parking structure is variable on a daily basis depending on
water table conditions and frequency/duration of rain events, and typically does not exceed 14,000 gallons per
day (gpd), with daily averages on the order of 8,000 to 10,500 gpd. The groundwater is collected through a
sump system and discharged to the City's sanitary sewer system. The cost of operation of this indirect
discharge system includes $ 5,000 in operation and maintenance, $14,000 for permit fees and sampling, and
$10,000 to dispose of the wastewater, for a total annual cost of $ 29,000. Under the IUP, the groundwater is
discharged without treatment (Appendix B).

The Northeast Cape Fear River is classified as 'aquatic life, secondary recreation, salt, swamp water' (SC Sw)
and is located within subbasin 03-06-23 in the Cape Fear River basin at the proposed discharge location
(assessment unit number 18-74-(61)). The proposed discharge location is illustrated on Figure 1. The
October 2005 Cape Fear River Basinwide Water Quality Plan (North Carolina Department of Environment and
Natural Resources [NCDENR], 2005) (the Basin Plan) describes the status and recommendations of impaired
waters in subbasin 03-06-23. The Basin Plan does not list the Northeast Cape Fear River [18-74-(61)] as being
impaired at the proposed discharge location. However, the Basin Plan does state that dissolved oxygen (DO)
readings in the Northeast Cape Fear River [18-74-(61)] were low in 39.3 percent of samples. The DO
standard for SC water is 5 milligrams per liter (mg/L), however as the Northeast Cape Fear River [18-74-(61)]
has a supplemental classification of Sw (swamp water), it is allowed to have lower DO readings and therefore
is not classified as impaired.

eolb� 1.3 Analytical data
Water quality data were collected from the discharge of the sump system in May and August 2007 and
submitted to the City of Wilmington under the IUP. The water samples were analyzed for metals, volatile and
semivolatile organic compounds (EPA Methods 624 and 625), ammonia, nitrate, nitrite, total Kjeldahl nitrogen,
biochemical oxygen demand, chemical oxygen demand, chloride, phosphorous, oil and grease, dissolved
solids and suspended solids. The analytical results for these samples are presented in Table 1. Additional
water quality data, including ammonia, arsenic, copper, pH and conductivity data collected periodically via grab
and composite sampling methods at the sump discharge, as presented in Table 2. These data were required
by the City of Wilmington under the IUP. Additional groundwater samples were also collected in May 2008,
the results of which are listed in Table 3. A review of these data shows that the parameters of concern are
arsenic and ammonia. The data collected to date represent the constituents of the groundwater with no
treatment. Laboratory analytical reports are included in Appendix C. Discussion on the anticipated
concentrations after a potential groundwater treatment process is presented in Section 1.4 below.
1.4 Groundwater treatment system
Groundwater will be recovered from the area beneath and surrounding the building using an array of extraction
wells. The purpose of these wells will be to reduce hydraulic pressure on the building foundation and thus
minimize groundwater seepage to acceptable levels to permit occupancy and use of the lower parking level.
An ion exchange system is proposed to reduce ammonia and arsenic levels in extracted groundwater to
anticipated discharge standards. The NCDENR Division of Water Quality (DWQ) permitting strategy for the
Cape Fear River dictates an ammonia limit of 2 mg/L. The expected arsenic limit is 10 micrograms per liter
(Ng/L), which is the water quality standard for human health. A treatability study was conducted to determine
the optimum treatment system configuration to achieve the target treatment goals. Results of the study
suggest that the proposed treatment system will be able to treat the recovered groundwater for ammonia and
arsenic and achieve effluent concentrations of < 3 mg/L for ammonia and < 10 for µg/L arsenic. The proposed
system consists of a pre -filter to remove suspended material, a series of ion exchange tanks to remove arsenic
and ammonia, and a pH adjustment system. Preliminary design analysis indicates that the treatment system
will be designed for an operating range of 2 gallons per minute (gpm) to 20 gpm and will be expected to have
an optimal operation rate of approximately 10 gpm. The discharge from the ion exchange system will be
conveyed to the stormwater sewer along Brunswick Street, which discharges directly to the Northeast Cape
Fear River. The treatability study report is included in Appendix D.

2.0 Alternatives
The most economic alternative, with the least environmental risk for water management is the current method
of direct discharge to the City of Wilmington WWTP (Section 1.1). However, this management scenario was
not accepted as a long-term approach by the City of Wilmington. The City of Wilmington conditioned the IUP
as a temporary disposal option as stated in the UP from the City (Appendix B). Therefore, the following
discharge alternatives were identified for further evaluation: land application/reuse, direct discharge, and a
combination of land application/reuse and direct discharge.
2.1 Land application/reuse
Land application using a landscape irrigation system has been identified as a discharge alternative for the
treated groundwater. The Site currently uses an automatic irrigation system for the landscaped and grassy
areas within the property. The existing irrigation system at the Site includes spray heads and drip lines.
Current maximum water consumption for the irrigation system is approximately 21,800 gpd. Since the
volume of water needed for irrigation is more than the expected treatment system effluent of 14,000 gpd, this
option would require the modification of the existing system to allow the use of both reuse and potable water.
The sole use of this alternative to dispose of the wastewater would also require storage for off -quality effluent
and periods when irrigation is not practicable. Retrofitting of the system includes providing cross -connection
controls and labeling all the reuse lines and appurtenances.
A water balance was developed to determine the storage volume necessary to store excess recovered
groundwater. To develop the calculations, AECOM assumed that the irrigation system utilizes 21,800 gpd and
to� the groundwater treatment system produces 14,000 gpd. Calculations are based on an average rain year
using data for the Wilmington Airport obtained from the State Climate Office for North Carolina. A basin with a
capacity of 670,000 gallons would be required for wastewater storage. A basin this size typically requires one
acre of land including required setbacks. Since the Site is fully developed, additional land would be needed to
locate the storage basin. PPD owns adjacent property north of Harnett Street that could be used to locate
such a basin. The property's assessed value is $1,341,505.00 and is an asset being considered for a future
expansion. A storage pond could be located on the vacant land resulting in a high cost for this alternative
associated with incorporating it into future development on the remainder of the site. See Appendix E for the
pond volume calculations and land assessment information.
The capital cost for this alternative is $ 828,200 and the 20-yr present value worth is $ 5,778,306 (Table 4).
2.2 Treatment and direct discharge (preferred alternative)
The Site is located approximately 500 feet from the Northeast Cape Fear River. Treatment and direct
discharge of the recovered groundwater may be implemented by discharging the treated water via an existing
stormwater pipe that runs adjacent to the building along Brunswick Street and discharges to the river. The
proposed discharge would enter the Northeast Cape Fear River at latitude 34 14' 35" and longitude 77' 57'
04". As discussed in Section 1.4, the ion exchange treatment system will be designed and operated to meet
applicable water quality standards and permit limits. The City of Wilmington has given approval for the
connection to the storm sewer (Appendix F).
The direct discharge alternative is the least costly and does not impact water quality in the Northeast Cape
Fear River, as it is anticipated to meet all water quality standards. The capital cost for this alternative is
$517,640 and the 20-yr present value worth is $5,464,514 (Table 5). Therefore, this is the preferred
alternative for disposal of the recovered groundwater at the Site.

AECOM Environment
`0� 2.3 Combination of alternatives
A third alternative available for disposing of the groundwater is to use the existing irrigation system in
conjunction with direct discharge. In order to implement this alternative, the irrigation/drip system has to be
retrofitted to accommodate the use of both potable and treated water and labeled to meet regulatory
requirements. In addition, a storage tank and pump station will need to be installed. The maximum volume of
water used for landscape irrigation is 21,800 gallons per day. Assuming the treatment system will produce an
average of 14,000 gpd of treated groundwater, the effluent could be used as irrigation water in its entirety
when irrigation is allowed. During periods when irrigation is not possible the effluent would be discharged to
the Cape Fear River under the NPDES permit. The capital cost for this alternative is $562,640 and the 20-yr
present value worth is $5,615,771 (Table 6).

3.0 Present value cost analysis summary
A present value of cost analysis (PVCA) was performed to identify the most economically feasible alternative.
AECOM assumed a discount rate of 4.9% to perform the calculations. Capital cost includes the groundwater
treatment system, construction of storage units, pumping stations, and modification of the irrigation system.
Recurring cost includes permit fees, permit monitoring expenses, labor, energy consumption, and
maintenance activities. Table 4 through 6 show detailed costs for each alternative. Table 7 summarizes the
PVCA for the three discharge alternatives evaluated. From the three options evaluated, the treatment and
direct discharge to the Northeast Cape Fear River is the most economically feasible alternative.

AECOM Environment
/O�N 4.0 Summary
This Engineering Alternatives Analysis evaluated three alternatives to address the disposal of treated
recovered groundwater from the Site: land application, conjunctive use (land application and direct discharge),
and direct discharge. The cost of a land application system is substantially higher than the other alternatives.
The storage lagoon and additional land costs makes this alternative not economically feasible. Although the
cost of a conjunctive use system is less than the cost for the land application system it doesn't provide an
economic advantage over the direct discharge system. The direct discharge system is the most economically
feasible alternative and therefore the preferred alternative.

Hazardous Waste Indicators

* ASG only
Highlighted toxics in the box at the
left indicate that exhausted carbon
and ion exchange resin from the
treatment system is considered a
RCRA hazardous waste for those
components and is subject to all
RCRA and DOT rules and
regulations governing handling and
transportation of hazardous wastes.
The absence of hazardous waste indicators is not to be interpreted to mean that Siemens Water
Technologies Corp. implies or warrants that spent carbon and ion exchange resin resulting from
waste water treatment is not a hazardous waste. The U.S. Environmental Protection Agency requires
the generator of the waste to determine whether a waste is a hazardous waste according to
regulations found in the Code of Federal Regulations, see 40 CFR 260. Siemens Water Technologies
Corp. testing is for the purposes of treatability and compatibility with its treatment systems.
Analytical methods are in accordance with Siemens Water Technologies Corp. standard operating
procedures and may not strictly adhere to EPA or equivalent test methods.

Subject: Request for Future Storm Sewer Connection
PPD Inc., 929 North Front Street, Wilmington
Dear Ms. Rodriguez:
The City of Wilmington is in receipt of your request for future connection to our Storm Sewer
System on behalf of PPD. We understand that you are currently pursuing an NPDES permit
from NCDWQ to discharge treated groundwater which is impacting the use of the lower portion
of the building at 929 North Front St and its courtyard. In general, the City of Wilmington
would approve of this request based on the following conditions:
• PPD will provide the opportunity for City staff to review and comment on plans related
to the actual connection the discharge to our system.
• PPD will provide documentation of the NPDES permit approved by NCDWQ as well
as all required monitoring documentation to the City of Wilmington Stormwater
Services Division.
• PPD will obtain a City right of way permit if appropriate for making the connection to
the storm sewer system and require that their contractor allow for City inspection of the
connection during its construction.
• PPD accepts full responsibility for any discharge not in compliance with their NPDES
requirements to include corrective measures that may need to occur within the City
system.
Should you have any questions, please contact me at 910 3415880 or
