Subject: Issuance of NPDES Permit NCO089206
Claire Sprayway Site Remediation Project
2100 North Church Street, Charlotte
Mecklenburg County
Dear Mr. McElveen:
The Division of Water Resources (the Division) hereby issues the attached NPDES permit for
the subject facility. We issue this permit 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.
Changes to the Permit DRAFT. After additional review of the monitoring database, the Division
notes that several parameters of concern were not detected in the effluent during the previous
permit cycle. Considering the lack of reasonable potential to exceed their respective water -
quality standards, DWR removed the permit limits for Toluene, Naphthalene, PCE, TCE, 1,1-DCA,
1,1-16CE, 1,1,1 TCA and 1,2-DCA. In keeping with permitting guidance, we have also reduced the
respective monitoring frequencies from Monthly to Quarterly [see Section A. (1)].
Request to Increase Flow. The Division acknowledges your request to increase Monthly Average
flow from 0.050 to 0.070 MGD. Unfortunately this cannot be granted. By Rule, flow increases
require additional information [15A NCAC 2H.0105(c)(2)] in the form of an Engineering
Alternatives Analysis (EAA). Should you wish to comply with this document, you may submit
an application and appropriate fees to modify this permit. Please see our website:
[http://poi-tal.nedenr.org/web/wq/swp/Ps/npdes/guidance].
Renewal Changes. The Division has updated your permit facility description, site map, and
added parameter codes to your effluent table for your convenience [see section A. (1.)]. Also
please note the future need for electronic DMR reporting.
Implementing Electronic Discharge Monitoring Reports (eDNMs). Please be advised that the
Division has implemented an electronic Discharge Monitoring Report (eDMR) program, in
accord with pending requirements by the Environmental Protection Agency (EPA). We include
in this permit the details to implement the eDMR program [see Section A. (2)].

Permit NCO089206
A. (2) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
[15A NCAC 02B .0200 et seq.]
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,
quarterlX monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent
Bioassay Procedure, " Revised February 1998, or subsequent versions or "North Carolina Phase 11 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 defmition of "detectable impairment,"
collection methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase
lI 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: NCDEQ / DWQ / Water Quality Permitting Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Water Quality Permitting 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 & reporting of the data submitted on the DMR & all AT Forms
submitted.
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.

If a Permittee is unable to use the eDMR system due to a demonstrated hardship, or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted,
and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3), or
alternative forms approved by the Director. Duplicate signed copies shall be submitted to the mailing
address above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be
submitted in writing to the Division for written approval at least sixty (60) days prior to the date the
facility would be required under this permit to begin using eDMR. Temporary waivers shall be
valid for twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted
electronically to the Division unless the Pennittee re -applies for and is granted a new temporary
waiver by the Division. Information on eDMR and application for a temporary waiver from the
NPDES electronic reporting requirements is found on the following web page:

Facility History. Plaze Corporation [current environmental consultant] applied to renew this permit,
application received January 5, 2015. The current site owners/operators (Swofford Associates Epoxy
Flooring) are not involved directly in site remediation. There have been significant efforts to define and
characterize the contaminant plume including two (2) previous incomplete attempts to remediate.
Groundwater contaminants include volatile organic compounds believed to have originated from onsite
metal cleaning operations utilizing chlorinated -hydrocarbon solvents. Additionally, contaminant plumes
originating off site may have comingled with onsite contamination. Time has generated decomposition
"daughter products" originating as Tetrachloroethene (PCE), 1, 1 -dichloroethene (1,1-DCE), 1,1,1 -
Trichloroethane (1,1,1-TCA) and others [see RPA discussion].
Treatment System and Discharee. Remediation facilities currently consists of an array of monitoring and
extraction wells, the later manifolded and routed subsurface to an onsite treatment building to remove both
vapor [air -stripper] and liquid product. Recovery wells are each equipped with a pneumatically -actuated
recovery pump providing dual -phase extraction [vapor.and lost product]. Treatment -system effluent, after
final compliance sampling, discharges to the City of Charlotte's storm collection basin [N. Tryon Street],
draining SE underground via the storm sewer to an unnamed tributary (UT) to Little Sugar Creek,
eventually discharging above ground to Little Sugar Creek.

Request to Increase Flow. The Division acknowledged the applicant's request to increase Monthly Average
Flow from 0.050 to 0.070 MGD. This request was denied. Flow increase requires additional information by
Rule [15A NCAC 2H.0105(c)(2)] in the form of an Engineering Alternatives Analysis (EAA). The cover
1ptter provided a link to DWR's website: [http://portal.ncdenr.org/web/wq/swp/ps/npdes/guidance].
Compliance. As with similar GW-REM projects, this facility is episodic in its operation with prolonged
periods of no discharge. Based on BIMS records for the period Jan2013 thru December 2013, the Division
recorded one (1) only limit violation (monthly average) for Toluene associated with the latest startup (not
assessed). All others are "frequency" violations automatically cited by BIMS. These were noted by the
ARO and Central Office as "no action BPJ" because the treatment system was shut down/not discharging
(see attached compliance history). No other violations to date.
Toxicity and Reasonable Potential Analysis (R.PA) - The Permittee's analytical database (Jan2011-
Jun2015) reported no concentrations detected above method -detection limits (MDLs) for the parameters
Toluene, Naphthalene, PCE, TCE, 1,1-DCA, 1,1-DCE, and 1,2-DCA. Therefore, the required reasonable
potential analysis (RPA) was not warranted for these parameter and the permit limits were removed from the
permits. Similarly, one parameter [1,1,1-TCA], was detected [seven (7) times in 20 sample events], but not
above its allowable concentration; this database does NOT show reasonable potential to exceed its standard
(see attached). Likewise, effluent WET testing results do not suggest toxicity to the environment [last five
(5) quarterly tests Jan2014-Apr2015 reported as "pass"].
