monitoring is not feasible, then the discharger shall record the approximate time that
discharge began and ended, along with the instantaneous flow at the time of the
effluent sampling.
2. Refer to A. (2.)).
There shall be no discharge of floating solids or visible foam in other than trace amounts

Permit NCO085731
A (2). CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 90%
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
March, June, September & December. 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 pass/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
Cornerstone Carillon, LLC, has applied for renewal of its existing NPDES Permit No.
NCO085731 to discharge 0.0316 MGD of remediated groundwater from its dewatering system
located at the Carillon Building GW Facility, 227 West Trade Street Suite 330, Charlotte, NC
28202. The treatment system outfall discharges via underground piping into the City of
Charlotte's Municipal Separate Storm Sewer System. The Storm Sewer System draining this
area discharges into Irwin Creek, which is Class C water in the Catawba River System. Due to
the inaccessibility of the discharge point, effluent sampling is conducted at a valve that has
been installed post -treatment, immediately downstream from the flow meter. Effluent flow is
measured instantaneously once a month using a flow totalizer.
The NPDES permit is for treatment of groundwater pumped during de -watering activities for
the Carillon Building (office building). Due to shallow groundwater, approximately ten feet
below the ground surface, a permanent de -watering system was installed to prevent uplift of
the lowest floor slab and flooring of the underground portion of the parking garage. The
treatment unit was initially installed to treat groundwater generated by de -watering activities
during construction of the building in 1988. The facility is located on the bottom level of the
parking structure with the permitted equipment secured in a locked room with an open-air,
grated roof.
The decision to continue treatment of the discharged groundwater was based on laboratory
analyses of groundwater samples obtained during construction that indicated low levels of
chlorinated solvents. The solvents originated from a former dry cleaners located up gradient of
the Carillon Building. A pretreatment system has since been installed to treat the groundwater
recovered from eight de -watering wells.
Shorenstein Realty Investors / Carillon Bldg GWR
Proposed NPDES Permit
Page 1

The existing groundwater dewatering and treatment facility consists of a carbon filtration
system consisting of:
■ Eight (8) dewatering wells,
■ A vertical polyethylene holding tank (est. 850 gallons),
■ Two (2) transfer pumps,
■ Two (2) poly -glass adsorbers containing 1,000 pounds of activated carbon each,
■ Control panel and associated piping valves,
■ Flow meters, float switches, gauges, and
■ Sample ports.
The treatment system is supplied by eight (8) dewatering wells each containing individual
pumps that are located within the footprint of the parking structure. The pumps deliver 13 to
22 gpm of recovered groundwater to the holding tank at an average rate of 13 to 22 gpm. The
float controlled transfer pumps move water from the influent holding tank through the
adsorbers and the totalized flow meter which meters the discharge to the stormwater sewer.
Toxicity Testing:
Current Requirement: Chronic Quarterly P/ F at 90%
Proposed Requirement: Same
INSTREAM MONITORING:
No Instream-stream monitoring will be required and none is required now.
TOXICANT PARAMETERS:
A reasonable potential analysis (RPA) was conducted for Tetrachloroethene, Iron and
Manganese (Attached). The data evaluated was reported between January 2003 - December
2004. Where data were available, both the chronic and acute (1/2) FAV) were evaluated for
reasonable potential

the facility's NPDES Permit application that was submitted during 10/04 to reflect
facility ownership name change in 12/04. FYI, this renewal has not been assigned as
of 2/1/05 and Charles may not be the permit writer. kevin.
