Dear Mr. Heller:
The Divisionof Water Resources theDivision) hereby issues the attached NPDES permit
modification for the subject facility. We issue this modification 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 Division: understands that you intend, in the short term, to dewater construction excavations, but
that you may also have future need to install permanent treatment for dewatering system(s) to service
subterranean structure(s) advanced below the groundwater surface. This permit may accommodate
both tasks, and may be modified as the project proceeds, at the Division's discretion (see Supplement
o Permit Cover Sheet).
We have examined your Engineering Alternatives Analysis (E ) and concur with, your conclusion
that discharge to surfface waters of the stare is the most viable discharge alternative based on costs in
an urban environment. We have also received denial of treatment at the local PTW, and' approval
from Charlotte -Mecklenburg for your discharge to the city storm drain.
-laving reviewed your application and your site -assessment documents, the Division recognizes the
subject site's history of impacts to the environment, apparently generated from ultiple sources over
time. At the onset, therefore, this permit must consider the treatment -system influent a cone le.
wastestream, and will require monitoring for a comprehensive list ofparameters qfconcern (P Cs) to
evaluate effluent compliance to sutface waters -quality standards. As you establish a discharge t
analytical database, the monitoring frequencies may be adjusted or eliminated, as data may warrant
[see footnotes, section A. (l .)].

STANDARD 1S ITIONS FOR NPDES PERMITS
Section A. Definitions
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events. These samples shall be
representative of the wastewater discharged during the sample perked.
3/Week
Samples are collected three times per week on three separate calendar days, These samples shall be representative of
the wastewater discharged during the; sample period.

The Federal Water Pollution ControlAct, also known as the Clean Water Act (C'W ), as amended, 33 USC 125 1, et.
seq.
Annual Avery.
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliforrn the geometric rnean'ofsuch discharges.
Arithmetic Mean

Bypass
The known diversion of waste streams from any portion of a treatment facility including; the collection system; which is
not a designed or established or operating mode for the facility.
calendar Day
The period from midnight of one day until midnight; of the next day. However, for purposes of this permit, any

Calendar Quarter
One of the following distinct periods- January through March, April through June, July through September, and
October through December.
Composite Sam trle
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 naL in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number r .and size of aliquots necessary, the time interval
between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or amornatically. Composite
samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a'24-hour period proportional to the rate of flow.
(2) ;Constant time/variable volume: a series of grab samples collected at equal time: intervals over a 24 hour period
of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(3) Variable time/constantvolume: a series of grab samples of equal,volume collected over a 24 hour period with
the time intervals between samples determined by as preset number of gallons passing the sampling point. Flow
measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the
preset gallon interval between sample collection fixed at no greater than 1 /24 of the expected total daily flow at
the treatment system, or

grab samples at least every six hours-, there must be a minnnum of four samples during a 24-hour sampling

Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Dail Discharge
rhe discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling, For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement, the
"daily discharge" is calculated as the average measurement of the pollutant over the day, (40 CFR 122.2; see also
"Composite Sample," above.)
Daily Maximum
The highest "daily discharge" during the calendar month.
Dqgy Sam fin,
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the

Appropriate flow measurement devices and methods consistent with accepted scientific practices shall be selected
and used to ensure the accuracy and reliability of meas arernenls of the volurne of monitored discharges. The
devices shall be installed, calibrated and maintained to ensure that the accuracy of the measurements is consistent
with the accepted capability of that type of device. Devices selected shall be capable of measuring flows with a
maximum deviation of less than 1 ti% from the true, discharge rates throughout the range of expected discharge

to the minimum detection or lower reporting level of the:. procedure. If no approved methods are determined
capable of achieving mini mum detection and reporting levels below permit discharge requirements, there the most
sensitive (method with the lowest possible detection and reporting level) ;approved method :must be used.

i"he projected cast for the purchase and installation of me groundwater treatment system
described above is estimated to be approximately $35 000, while the annual coast for O&M and
groundwater testing is estimated to range from approximately $5,000 to $1(,000.
4.0 DISCUSSION
The Parkwood Station Site project includes the demolition of existing structures and construction
of 4 and 5-story residential buildings, with 309 units and a clubhouse, wrapped around a 6-level
parking garage. Due to the presence of shallow groundwater, it is anticipated that dewateri a
may be required during construction activities, and a permanent high-water sub -slab underdrain
system will be installed beneath some of the project's structural slates. Based upon the analysis
of alternatives for managing recovered groundwater, orb -site treatment and discharge to the storm
water system through this proposed NPDES individual permit is the most cost-effective and
practical solution for this Brownfield project.

tering System
Chris,
Nice talking to you this morning,
The system below is a good example of what we could build for your application. That system has a 10 GPM gear puma, bag filter, and 2x 2001b carbon tanks, It
included a control panel (remotely mounted so it is not pictured) with controls for the pump as well as pressure switches on each tare with cellular telemetry to
notify of high pressure conditions, That .setup was about $25,000, If you don't need the gear pump and the rather bells and whistles the coast would be less;
I've sent a request to my carbon vendor to find out how often you'd need to change the carbon, As soon as I hear back I'll let you know,
Thanks!
