Subject. NPDES Electronic Reporting Requirements
AquAir rmediaion site
NPDES Permit Number; NCO086673'
Dear NPDES Permittee:
The U.S. Environmental Protection Agency (EPA) recently published the National Pollutant Discharge
Elimination System (NPDES) Electronic Reporting Rule. The rule requires NPDES regulated facilities to
report information electronically, instead of filing written paper reports. The rule does not change what
information is required from facilities. It only changes the method by which information is provided (i.e.,
electronic rather than paper -based).
EPA is phasing in the requirements of the rule over a 5-year period. The two phases of the rule, and their
key milestones, are:
• Phase 1—Starting on December 21, 2016, regulated entities that are required to submit Discharge
Monitoring Reports (DMRs) will begin submitting these reports electronically, if you are currently
reporting your DR data electronically using eDMR then you simply need to continue reporting
in the same way as you are now. The key change is that, starting on December 21, 2016,
electronicreporting of DMRs will be required, instead of voluntary.
• Phase 2—Starting can December 21, 2020, regulated' entities that are required to submit certain
other NPDES reports will begin; submitting these reports electronically. Reports covered in the
second phase include Notices of Intent to discharge in compliance with an NPDES general permit,
Sewer Overflow/Bypass Event Reports, and a number of ether NPDES program reports.
Incorporating Electronic Reporting Requirements into NPDES Permits
The NPDES Electronic Reporting Rule requires authorized NPDES programs to incorporate electronic
reporting requirements into NPDES permits beginning December 21, 2015. Under the new rule, the
electronic reporting process supersedes the paper reporting process. According to our files, your NPDES
permit became effective; after November 2013, and should contain the requirement to electronically
report your Discharge Monitoring Reports using NC DWR's eDMR system.
In addition to requiring permittees to report information electronically, the rule also requires permittees
to identify the initial recipient for the NPDES electronic reporting data [see 40 CFR 122.41(l)(9)j. Initial
State of North Carolina I Environmental Quality I Water Resources
1617 Mail Service; Center j Raleigh, North Carolina 27699-1617

recipient of electronic NPDES information from WDES-regulatedfocilities (initial reci,
entity (EPA or the state authorized by EPA to implement the NPDES program) that is
for receiving electronic NPDES Data [see 40 CFR 127.2(b)]. Permittees are required I

18, 2016, EPA must identify and publish on its web site and in the Federal Register a

toot will be available as well.

Subject: Waiver of Monthly Reporting Requirement
SNL Corporation— Aqua Air Groundwater Remediation Site
NPDES Pe` it NCO086 '73
Mecklenburg County
Dear Mr. Gilchrist:
Title 15A of the North Carolina Administrative Code, Subchapter 2B, Section .0506 gnurnerates specific
reporting requirements applicable to holders of NPDES permits issued by the State of North Carolina,
15A NCA.0 2B .0506 (a)(1)(E) states that permittees must continue to submit monthly discharge
monitoring reports (DMRs) to the Division of Water Quality, even when there is no discharge from', the
facility during the reporting period. This requirement may be waived by the Director of the Division of
Water Quality (or her designees) during extended periods of no discharge.
I have reviewed. the November 2, 2011 correspondence submitted can SNL. Corporation's behalf by Mr.
Robert L. Griffin, P.E. of Shield Engineering. The letter stated that operation of the subject.groundwater
treatment system will remain suspended for an undetermined period of time, allowing assessment
activities to be performed that will determine if the site may be entered into the Brownfields program.
During this time, no groundwater extraction, treatment or discharge will occur. Once the assessment is
completed, the Division will be advised of future plans at this site and whether the discharge of treated
groundwater will be necessary.
After reviewing your request and considering the recommendation of the staff of the Mooresville
Regional Office, I have agreed to waive the requirement to submit monthly DMRs for the subject
facility, effective with the November 2011 DMR. Additionally, I hereby waive the requirement for
operator visitation at this facility. The facility should take all necessary steps to ensure there will be no
direct discharge from this system to waters of the state. Please keep the Surface Water Protection
Section of the Mooresville Regional Office apprised of any pertinent developments that arise regarding
groundwater treatment and disposal from this facility. Please be mare that if the facility exhibits a
potential for discharge of wastewater, then visitation, monitoring and reporting must resume as required
by the terms of the permit and North Carolina's environmental laws. Conversely, if it is determined that
no additional groundwater remediation is required at the site, rescission of the permit should be
considered.

GENERAL:
The facility was last inspected on November 29, 2006, by Mr. Andrew Martin of the
Mecklenburg County Water Quality Program (MCryWQP). A Compliance Evaluation Inspection
Report was issued on January 4, 2007.
PERMIT:
The facility's current permit became effective July 1, 2005 and will expire on January 31,
2010.The facility; is permitted to discharge 0.0864 MGD of treated water from air on -site
groundwater remediation system to an unnamed tributary to Steele Cheek..
The facility was originally constructed to include the following components: extraction
wells, submersible pumps, surge tank, air stripper, particulate big filter, liquid -phase carbon
absorption, and dial flow meters (influent and effluent).
The pernrittee has re -engineered the treatment works to more aggressively treat
contaminated groundwater. Changes include the addition of two new recovery wells (five total),
an upgraded six -tray air stripper (replacement), the addition of a second liquid -phase granular
activated carbon unit as a polishing or finishing step, and the replacement of existing controls,
piping, and related electrical components. An Authorization to Construct was issued on august
, 2003 for the changes made to the treatment works.
The certification classification for NCO086 73 requires that the facility have an Operator
in Responsible Charge. (ORC) with a Grade 1 Physical Chemical Water Pollution Control System
(PC-1) certification. The facility is staffed (ORC and back-up) with personnel that possess the
appropriate operator certification. The Division of Water Quality Compliance Database currently
shows Mr. Robert Griffin as the ORC and Mr. John. Hawkins as the Back-up ORC. However,
the October and November 2008 Discharge Monitoring Reports note that Mr. Jeff
Nicholson is the ORC at the facility. Please complete the attached ORC form and have it
signed by the per ittee if there has been a change to the ORC at the facility; the form must
be submitted within 120 days of an ORC change.
RECORDS/REPORTS:
Discharge Monitoring Reports (DMRs) were reviewed from the period September 2007
through August 2008. No deficiencies in record keeping were rioted.
FACILITY SITE REVIEW:
The treat and pump system has not discharged since mid -November 2008. The ORC i
working to ,get the system back in full operation following a permit exceedance for carbon
tetrachloride. According to the ORC approximately 58 air -sparking wells, 35 monitoring wells,
and five recovery (extraction) wells have been installed across the site:

Report on Aquair Groundwater Treatment System Upset
On November 13, 2008 Prism Labs in Charlotte, NC confirmed results from samples
collected at the Aquair Groundwater Treatment Facility on November 3, 2008. This
sampling event included laboratory detections of Carbon Tetrachloride and
Tetrachloroethene in the treatment system effluent. Tetrachloroethene analysis did not
exceed permit limitations. Analytical results from analysis of the Aquair samples
indicated a Carbon Tetrachloride concentration of 93 microgram per liter. The permit
limits for Carbon Tetrachloride is 15.6 micrograms per liter.
PEeJiLninaa Investigation and Evaluation
One possible scenario that appears to have had an impact on the operation of the
treatment systems relates to the air stripper condition upon preliminary investigation:
It appears that the air stripper pores started to. clog d the air to the stripper blower was
able to flow through the tray pores effectively which may have resulted in short
circuiting and loss of effectiveness. The metal stripper prevents the operator from
actually seeing the flow as a plastic body stripper might or a tray with portholes or hand
-
ways. Therefore, this condition could not be detected by the operator.
In the Aquair Treatment System the Air Stripper is designed as the primary treatment unit
with carbon serving as a polishing step. Short circuiting of the stripper, although
detectable, potentially had a major effect on the efficiency of the entire treatment
system-
Proggled Corrective Action Plan
Shield .personnel will fully dismantle the stripper and clean (i.e. pressure wash and clean
with acid to remove calcium carbonate build up) the trays. After completion of the
cleaning, process flow will be directed back to the air stripper. Control samples will b
collected after the stripper to assure proper removal of pollutants. Sampling will also be
conducted at the time to evaluate the status of the primary and secondary carbon units.
Water from this evaluation process will be recycled to the influent surge tank and not
discharged to the receiving stream until such time sample results indicate the effluent
meets permit standards.
Shield will institute a quarterly stripperinspection process that will involve 2 people
opening the top of the stripper and visually inspecting the top tray for growth and
accumulation that could potentially cause a recurrence of these circumstances.

Five Day Notification of an Accidental Release
Aquair Wastewater Treatment Facility
Mecklenburg County, North Carolina
Shield Engineering PrQject No. 1040082-06
Dear Mr. Leslie,
Shield Engineering, Inc. (Shield) is providing formal notification of an accidental release of
approximately 1000 pounds of carbon from a treatment vessel equipment failure onsite at the Aquair
groundwater remediationtreatment facility to the discharge stream. This notification is on behalf of
SNL, LLC owner of the facility,
Robert L. Griffin, Operator in Responsible Charge (ORC) called John Leslie in the Mooresville
Regional Office of the Department of Environment and Natural Resources (DENR) Surface Water
Protection Section on August 6, 2003 at approximately 3:15 put to report the release and comply
with the 24 hour notification requirement.
The release occurred between the July 291h site visit and the time Shield's Robert L. Griffin, ORC,
visited the site on August 6, 2008. Immediately upon discovering the release the treatment system
was shut down pending the repair of the carbon vessel. Due to the release of carbon, the effluent flow
rneter malfunctioned and did not indicate discharge flow volume from July 29, 2008 until the system
was shut down on August 6, 2008. 1-he effluent flow meter was cleaned and is now operating
properly.
As we discussed the carbon should be inert and not pose a threat to the environment or stream.
However, in good conscience the owner hired Stat, Inc., a vacuum truck service, to remove the
carbon from the stream on the same day it was discovered, TetraSolv Filtration, Inc. removed the
carbon from the site on August 8, 2008 and will recycle it with the other carbon removed from the
vessels during repair and cleaning. Photos of before, during and after the cleanup are attached.

GENERAL:
The Mecklenburg County Water Quality Program (MC C P) last inspected the facility on
August 24 2005.. A Compliance Evaluation Inspection (CEI) Report was issued on September
2 , 2005:
PERMIT:
The facility's current permit became effective July 1, 2005, and will expire on January 1,
2010. The facility is permitted to, discharge 0.064 MCD treated water from an on -site
groundwater remediation system to an unnamed tributary to Steele Creek.
The facility was originally constructed to include the following components: extraction
wells, submersible pumps, surge tank, air stripper, particulate bag filter, liquid phase carbon
absorption, and ducal flow meters (influent and effluent)'
The facility has re -engineered the treatment works to more aggressively treat
contaminated groundwater. Changes include the addition of two new recovery wells (five total),
an upgraded 6-tray air stripper (replacement), the addition of a2"d liquid phase granular activated
carbon unit as a polishing or finishing step, and the replacement of existing controls, piping, and
related electrical components. An Authorization to Construct (A to C), was issued on August 2,
2005, for the changes made to the treatment works.
The certification classification for NCO0 6673 requires that the facility have an Operator
in Responsible Charge (C RC) with a Grade I (or higher) Physical Chemical Water Pollution
Control System (PC-1) certification. It appears that the facility is staffed with personnel (D.
Crawley, PC-2 ##2 21 ) that possess the appropriate operator certification. However, the
Division of "Water Quality's database indicates that neither an CRC nor a Pack. -up ORC"> has been
designated for the AcluAir W TP. Please use the enclosed Water Pollution Control System
ORC Designation Form to designate an ORC for the Aqu. it WWTP.
DMRs from November 2005 through October 2006 were reviewed during the inspection,
No deficiencies in record keeping were noted.
FACILITY SITEREVIEW:
During the inspection, disconnected piping and pumps were observed, verifying that the
facility was currently non -operational clue to a pump failure. The O C expects the plant to be
operational again on November 30, 20t?Ci,
According to the CRC, approximately 58 air-sparging wells have been installed across
the site. Also, two new recovery (extraction) wells have been installed for a total of five recovery
wells. There are also approximately 55 monitoring wells on site. New components added

through the A to C including a new upgraded air stripper and 'an additional liquid
it will allow for more aggressive groundwater treatment.
Numerous 55-gallon drums of soil cuttings (from the new air-sparefineei
again observed on site during the inspection as related to new well installation in '.
FLOW MEASUREMENT:
When operational, the;AquAir facility continuously monitors both influeni
flow using computer -based technology. Facility records indicated the effluent floc
replaced and calibrated on October 20, 2006.
EFFLUENT/RECEIVING WATERS:
The facility discharges to an un-named tributary of Steele Creek, which is

Request for Remission for Notice of Violation and Assessment of Civil Penalty of
Case # LV-2006-0116 Against SNI, Corporation
AquAir Waste Water Treatment Plant
Mecklenburg County, North Carolina
Shield Engineering Project No. 1040082-06
Dear Mr. Gleason,
This letter is to request Remission for the Notice of Violation and Assessment of Civil Penalty for
Case # LV-2006-0116 as stated in your April 28, 2006 letter. Shield Engineering (Shield) on behalf
of SNL Corporation (SNL) request remission of the Notice of Violation and/or Assessment of Civil
Penalty on the follow grounds.
• Violator promptly abated continuing environmental damage resulting from the violation,
• Violation was inadvertent and/or the result of an accident,
• Historic assessment of civil penalties.
• Cost of civil penalty would, be better applied to additional treatment system safe guards and
remedial actions.
Detailed breakdown of our request for remission of the Notice of Violation and Civil Penalty is listed
below.
1) Violation was promptly abated, negating continuing environmental damage
resulting from the violation.
Effluent analytical samples were collected on February 28, 2006 with verbal results of the
exceedance of the permit limitations received by Shield on March 13, 2006. Effluent concentrations
of 910 micrograms per liter (ug/L) carbon tetrachloride and 73 ug/L tetrachloroethene, were above
the site NPDES permit limitations of 15.6 ug/L and 31.1 ug/L respectively. Shield, with concurrence
from SNL obtained control samples from the AquAir WWTP Treatment System (WWTP) and
immediately shut down the WWTP, on the same day verbal results were received.
4301 Taggart Creek Road Telephone [phone]
Charlotte, NC 28208 www,shieldengineering.com Fax 704,394,6968

Shierverballyverbally reported the exceedence of permit limitations to NCDENR Mooresville Regional
Office
Office and followed up with a letter describing the cause of the exceedance and efforts made to
correct the cause of the exceedance. Efforts made to correct the cause of the exceedance included
backwashing the carbon polishing treatment units and adding cleaning of the air stripper float tree.
After careful consideration and receipt of the analytical results from the control samples indicating
levels of the NPDES monitored parameters below reporting levels the WWTP was re -started on
March 22, 2006. Shield monitored the treatment system for proper function and added cleaning of
the air stripper float and backwashing of the carbon units to the regular system maintenance check
list,
2) Violation was inadvertent and/or the result of an accident.
In February, 2006 the float switch for the air stripper sump became stuck and it is suspected that
inadequately treated groundwater flooded the carbon units. Concurrently the back pressure for the
carbon units increased. The system discharge rate near the end of February was low due to the
activated carbon units requiring backwashing.
3) Historic assessment of civil penalties.
The AquAir WWTP has been violation free since September 2004. A new groundwater treatment
system was installed in 2005 in order to more adequately treat the recovered groundwater and more
adequately mitigate possible environmental impact from the groundwater contamination.
4) Cost of civil penalty would be better applied to additional treatment system safe
guards and remedial actions.
The $278.95 civil penalty would better be applied to continued remedial efforts to remediate the
contaminated groundwater and enhancements to the groundwater treatment system such as
replacement of the granular activated carbon units within the carbon polishing treatment. SNL has
voluntarily expended great sums of money and efforts to remediate the site contaminated
groundwater and adhere to applicable environmental regulations. Penalizing SNL for one small
mechanical failure of the groundwater treatment system would not serve any positive action.
Shield and SNL would greatly appreciate your remission of the Notice of Violation and/or Civil
Penalty, The groundwater remediation and treatment systems will continue to be run at the highest
standards of operation.
If you have any questions or for further discussion concerning this report, please feel free to contact
the undersigned at [phone].

be provided in the proposed air stripper. Please clarify.
(b) Please provide expected influent VOC concentrations, and document that the proposed
air stripper is capable of producing effluent results below the NPDES permit limits.
(c) Will the increased VOC removal ftom the proposed air stripper affect any air quality
permit required by this WWTP?
3. Regarding the proposed addition of anotber 1,000 pound granular activated carbon (GAQ unit
(liquid phase):
(a) it is not clear what amount of VOC removal is necessary from the GAC its in order
to achieve the PDES permit Limits, or if the GAC units are essentially acting as a
treatment safety factor. What are the removal efficiencies of the existing GAC it,
and the proposed one? Please clarify.
(b) Is the GA C material in the GAC units replaced on a periodic basis? at is the
frequency of replace ment9

10 Proiect Hist
Thy AquAir site is located at 13300 Sam Neely R oad In Mecklenburg County, North
Carolina (Figure 1). Previous operations at the site consisted of: vanadium catalyst
manufacturing, ` g, solvent recovery, reclamation and blending, bulk chemical repackaging,
labt tory services, and chromium compound anufacturing. All facility operations
ceased by 1988. Since that time, the site structures have been removed. A railroad track
divides the site into two tracts (Figure 2). The northeastern tract contains an unnamed
tributary to Steel Creek and a wastewater treatment facility that currently treats
groundwater ` covered from three groundwat6r recovery wells located on the
southwestern portion of the facility. Cont l titan at the site consists of metals,
including arsenic, cadmium, chromium,lead, d vanadium in the soils and volatile
organic compounds (VOC) in the sails and groundwater.
Site managed remediation is being b the Inactive Ha ardour Sites Branch (IRSB) of the
y
North Carolina Department of Environment and Mural Resources (NCD NR), under
the registered Environmental Consultant (C) program. VOC contamination is being
( reroediated by two remedi Lion technologies Air sparging is utilized to remediate the
shallow aquifer contamination, d is not ttdressed nor an issue for this application.
Deep aquifer contamination is being remediated using a Groundwater Recovery System
(GT S) (Drawing 1). The gmundwater is removed from the deep aquifer by means of
submersible electrical pumps placed in Igoundwatel r recovery wells which then transport
it to the Wastewater Treatment ent Plat (, TP) via underground piping (Drawing ).
e Aqu air WWTP operates under NPDES Permit # lrCO08 i67361 and commenced
operation on November ber 1, 2000, under anag ei�t of Sc E. In April of 2004 Shield
Engineering, Inc. (Shield) assumed management of the c RS at the request of SILL, TLC
(Site Owner). ; Two 'Worth Carolina Licensed Wa tewater Operators on Shield's Staff,
serve as Operator in Responsible Charge and Back up Operator in Responsible Charge
with licen ores equal to or greater than required by the site NPDES permit and North
` Car+ lira Statutes.

Dear Mr. Olchrist:
Enclosedwith this letter is a copy of the draft permit for your facility. Please review the draft very
carefully to ensure thorough understanding of the conditions and requirements it contains
The draft permit contains the following significant changes from your current permit:
I
# A Reasonable Potential Analysis (XPA) was performed on data submitted by the facility from
December 2000 through September 2004 to determine the need in maintaining permit limits and
monitoring for particular effluent characteristics. As a result of the RYA, monitoring has been
eliminated in the draft for 18 of the 23 parameters found in the existing permit.
Please submit any comments to me no later than thirty days following your receipt of the draft,
Coo mment$ should be sent to the address listed at the bottom of the page. If no adverse co is are

In behalf of the SNL Corporation, Shield Engineering, Inc. (Shield) is pleased to submit
one original and one copy of the August, 2004 Effluent Report (DWQ Form - I.1) for
the above referenced AquAir Waste Water "Treatment Plant (AquAir WTP). The facility
will continue to submit monthly effluent reports as required by the National Pollutant
Discharge Elimination System DES) Permit No. NCO08 73.
Based on review of the sample analytical data in June, which demonstrated the need for
returning to carbon treatment, and also due to a power surge (presumably from a lightning
strike) the AquAir WTP was not operational from. July 1, 2004 through August 15, 2004.
Shield restarted the treatment system on August 16, 2004 after addition of carbon and
repair of the control panel.
Neither Shield nor SNL Corporation has received the NPDES permit renewal application
from NCDENR, Shield contacted NCDENR and requested a renewal application and was
informed that the NCDENR was behind on sending renewals out, and a renewal would be
sent.

Che AgtzAir WWTP did not operate from Jtrly 1, 200 through August I5, 2t?04 due to issues associated with the addition of carbon
filtration for adequate treatment and issues associated with a power surge presumably from a lightning strike in early July 2004.
The power surge destroyed the PLC (Programmable Logic Controller) for the treatment system. System repairs were conducted in
July and the first two weeks in August of 2004. The site ORC was present on site during repairs. The AquAir WWTP was
restarted on August 16 2004
Based on review of the sample analytical data for August 2004, the AquAir WWTP operated within the limitations as specified in
the site NPDES Permit.
Attached are the original analytical results for August 2004 effluent sampling and a copy of the aquatic toxicity results. The
original aquatic toxicity results have been forwarded to the Environmental Sciences Division ofNCDENR.
The AquAir NPDES Permit expires on January 31, 2005. The NPDES permit renewal has not been received to date. Shield
Engineering employees contacted NCQE�NR to request a permit renewal application be sent and were told the NC L1ENR-DWt
was six months behind on renewal applications. Shield was told tlae a alicatom would be mailed intlte meal future.

Re: Notice of Violation dated September 22, ` 004
Dormer AquAir Facility
1300 Sara. Neely Road
Charlotte, Mecklenburg County
NCD 074511361
Shield Project #104002-2
Dear Mr. Bridgeman:
Regarding the Former AquAir facility at the above address, a Report issued as a Notice o
Violation (Report) elated September 22, 2004 was received from the North Carolina Department
of Environment & Natural Resources (NCDENR). The Report detailed deficiencies and
violations under the Records/Reports and Self -Monitoring Program headings. Shield
Engineering, Inc, (Shield) on behalf of SNL, LLC is responding to this NOV.
Included in our response are amended Discharge Monitoring Reports (DMRs) prepared by
Shield and S&ME, a previous consultant that was in responsible charge during the time period
that some violations and/or deficiencies occurred. Also included are the requested responses to
the violations, some provided based on conversations with S&ME. Shield can not guarantee
accuracy or validity of information obtained from others, but has no reason to doubt the validity.
Response to Records/Reports section of Report
1. Amended January, 2004 DMR supplied by S&ME (Attached).
`?. Amended May, 2004 DMR supplied by Shield (Attached.).
3. Amended June, 2004 DMR supplied by Shield (Attached.).
Response to Self Monitoring Program section of Report
I . The DMR dated December 2003 indicated that compliance samples uvr*e collected on
December 30, 2003, when the flaw was reported at 0. 000 iiIGD1
S ME stated to Shield on October 13, 2004 that the system had been "down" and when
they inspected the system on December 30, 2003 they were able to get it operating. They
4301 Taggart Creek Road Telephone 704,394,6913
Charlotte, NC 28208 www.sh eldengineering.cam Fax 704,394.6968
t4 r

sampled the effluent thereafter. The consultants in charge of this project changed from
S&ME to Shield in May 2004. Shield will endeavor not to have a similar occurrence.
2-13. Response to violations 2 through 13 are addressed in this section. The DUR dated April
004 indicates that only one sample was collected fvr analyses of the required
parameters in April 2004. The suNect permit requires samplin ./br these parameters
twice per month.
The consulting company in charge of this project changed during this monitoring period.
It was the understanding of Shield: that S&ME had performed all required monitoring
events, up to the date of transferring responsibility of this project to Shield. In May 2004.
it was learned that on April 13, 2004 S ME sampled the effluent for Toxicity Testing but
not chemical testing. On April 23, 2004 Shield sampled for all of the required parameters
This was noted in the May 2004 DMR.
Shield is now in charge of the facility operation. Shield's Project Manager is tracking all
sampling requirements and due dates. In addition, Shield has an inner company
scheduling calendar for reminders to the Site Project Director and Project Manager of all
site requirements and due dates. These procedures at Shield should ensure timely and
complete sampling per the permit.
14-15. Response to violations 14 & 15. The 1 MR dated ,lane 2004 reported a permit
exceedance for Carbon Tetrachloride and Tetrachlor oethene as sampled on hone 30,
2004.
Additional groundwater recovery wells were added to the system in June 2004.
Apparently this increased the contaminant loading to the system. At approximately the
same time that we confirmed the exceedance of the permit, there was a power surge that
damaged some of the system controls. For these two reasons, the system was left "down"
until approval was received from the NCDENR to put the carbon filtering portion of the
system back on line, and the system controls were repaired. One 1,000-Lbs liquid phase
carbon unit was installed on August 16-17, 2004 with concurrence from NCDENR
Raleigh Central Office"s Tom Belick. The system has been operating in compliance
with the permit since August 17, 2004.
Shield is in the process of requesting NCDENR permission to add another 1,000 ZLbs
carbon unit to be placed in parallel with the current 1,000-Lfbs carbon unit to ensure
compliance with NPDES permit discharge limitations. System effluent sampling will
continue as directed in the site NPDES permit NCD 074511361.
Shield has amended the DMRs as requested in the September 22, 2004 Report and they are
attached. Copies of analytical data have not been included. Also included please find a copy of
the Report.

e table for coiew of the sample analytical data and continuous discharge effluent flow records, the AquAir WWTP operated in
ith NPDES Permit No. NCO086673 during April 2004 with the exception of no effluent' analytical samples being
irst portion of April 2004. Only toxicity sampling on the effluent was conducted the first sampling event by S& E.
Operation and maintenance responsibilities of the AquAir WWTP were transferred from S&ME to Shield on April 22, 2004. It was
Shield's understanding at the time of transfer that S&ME had sampled the effluent earlier in the month; as a result Shield only
sampled the effluent the second portion of the month. Shield will be performing operations, maintenance and sampling in
compliance with the current NPDES Permit number NCO086673 until directed otherwise.

GENERAL:
The Mecklenburg County Water Quality Program (MCWQP) last inspected the facility on
January2, 2003. A Compliance Evaluation Inspection ( El) ) Report of Deficiency was
issued on January 28, 2003.
PERMIT:
AquAir WWTP's NPDES Permit became effective February 1, 2000. The facility is
permitted to discharge 0.0864 MGD treated water from an on -site groundwater remediation
system to an unnamed tributary to Steele Greer. The current permit will expire on January 31,
2005.
e facility is comprised of the following components. extraction wells, submersible
pumps, surge t, air stripper, particulate filter, and flow meter. The AquAir WWIT facility
received approval from DWQ to remove the liquid phase carbon absorption component from the
treatment works in March 2 01t Documentation of this facility modification is maintained in
DWQ's facility file.
RECORDS/REPORTS:
DMRs and nmintenance records from September 2002 through August 2003 were
reviewed during the inspection. facility records and reports appeared to be well organized and
were readily available. One deficiency in record keeping was noted, as follows:
Marginal
N SITE
The treatment system not discharging when MCA QP personnel arrived for the
inspection, however, the ORC reported that all components were operational d subsequently
reset the system components of the treatment system appeared to be operating properly and
the effluent discharge was observed. A locked gate and fence surround the facility, providing
controlled access: All compliance samples continue to be collected at a designated post -treatment
sampling valve.

FLOW MEASUREMENT:
Both influent and effluent flow e continuously monitored using computer -based
technology (Signet vortex flaw meters). The monitoring equipment is inspected for residue and
cleaned approximately every 6-months. Facility records indicated that flow meters were last
serviced on Feb 10, 2003 d the RC reports that service is scheduled again in the next few
week.
EFFLUENT/RECEIVING AT
The facility discharges to an unnamed tributary of Steele Creel, which is a Glass C water
in the Catawba River Bassin. Effluent discharged from the system. during the inspection appeared
to be clear and odorless. The tributary appeared to be flowing normally under ambient conditions
d no effluent impacts in the receiving water were discernible.
SELF -MONITORING
Facility effluent monitoring appeared to be consistent with permit requirements with the
following exception:
1. The DMR dated.. December 2002 indicated that laboratory hold -times were exceeded for
samples collected on December 18. An attached letter from pace Analytical (the contract
service °ce laboratory) indicates that a laboratory equipment failure resulted in broken hold -
times for 'samples that were analyzed under EPA Method 8260. This constitutes one (1)
failure to monitor for each of the nineteen'(1 ) required. VOC.` parameters. The December
DMR correctly identified the non-cornpliant facility status.
Facility effluent analytical results were reported to be within permit limitations with the
following exception:
. The DMR dated April ` 003 indicated that the facility failed to "Pass" the Chronic Toxicity
test for samples collected on April 8 and April 11. This constitutes one (1) violation of
the subject permit. The April DMR correctly identified the non -compliant facility stat
d subsequent monitoring was completed per the permit requirements.
Two other deficiencies in monitoring were observed during the period of review. loth`
deficiencies were related to compliance sample collection, as follows.:
2. The DMR dated: September 2002 indicates that compliance samples; were collected on
9/23, whenflow was reported at 0 1623 MGD. This represents flow in excess of 10 times
the monthly average,

SELF -MONITORING PROGRAM (Continued):
3. The DMR dated November 2002 indicates that compliance samples were collected on
11 11, when flow was reported at 0.0000 MGD.
Compliance samples should be collected, at a time when the discharge is characteristic of
the entire period that the sample represents.
RATING: Unsaliyfactory
OPERATIONS & MAINTENANCE:
Overall operation and maintenance strategies appeared appropriate for the facility. The
grounds and buildings appeared to be well maintained and good housekeeping practices were
apparent.

Dear Mr.Iridgem
On behalf of the SNL Corporation, S&ME; Inc. is submitting this response to the Notice of
Violation (NOV) letter elated October 10, 2003 for the Aquair WWTP in Mecklenburg County,
North Carolina. The AquAir WWTP is operated to treat groundwater recovered from the site prior
to discharge to the unnamed tributary located on site.
In response to the noted deficiency under RecordslReports, S&ME is attaching the amended
Discharge Monitoring Report D ) for February 2003 with the correction for the date on which
analytical results for effluent sampling was recorded. Due to a typographical error, analytical
results for the effluent sample taken on February 13, 2003 were reported incorrectly on the DMR on
February 15, 2003. The facility will continue to submit monthly effluent reports as required by
DES Permit No. NC0086673.
In response to the noted deficiencies in monitoring under the Self -Monitoring Program, amended
reports for September 2002 and November 2002 are being submitted. The flow on September 23,
2002 was recorded incorrectly as 0.1623 :million gallons per day ( D). The correct flow for the

day was 0.01623 MGD. Attached for reference are the September 2002 flow log and the amended
DMR for September 2002 indicating the correct flow for September 23, 2002.
Due to a typographical error, the flows on November 11, 12, and 13, 2002 were reported incorrectly
on the DMR. The flow for November 11, 2002 was 0.0103 MGD, not the incorrectly reported
O.00OOMGD. The flow for November 12, 2002 was 0.0157 MGD, not the incorrectly reported
0.0103MGD. The flow for November 13,2002 was 0.0183 MGD, not the incorrectly reported
0.0157MGD, Attached for reference is the November 2002 flow log. Attached is the amended
DMR for November 2002 indicating the correct flow for November 11, 12, and 13, 2002.
In response to the noted violation for failure to monitor nineteen (19) required VOC parameters in
(the contract service laboratory) wrote a letter stating that a laboratory equipment failure resulted in
the broken hold -times for samples that were analyzed under EPA Method 8260. Pace Analytical
verbally reported the incident to S&ME on January 3, 2003. That saine day, S&ME sequentially
notified Samar Bou-Ghazale of the North Carolina Department of Environment and Natural
Resources ("NC DENR!') Water Quality Section, Jeff Price of the Mecklenburg County Land Use
and Environmental Services Water Quality Program, and Richard Bridgeman of the NC DENR
Water Quality Section of the incident. S&ME also collected another effluent sample for VOC
analysis on January 3, 2003.
Samar Bou-Ghazale and Richard Bridgeman stated that the incident should be reported in the
December 2002 Discharge Monitoring Report. Samar Bou-Ghazale recommended resampling the
effluent as soon as possible, which was done on January 3, 2003. Richard Briidgeman stated that it

GENE
e Mecklenburg County Water Quality Program (MCWQP) last inspected the facility on
January 2, 2003. A Compliance Evaluation Inspection (CEI) Report Notice of Deficiency was
issued on January 28, 2003.
PERMIT:
AquAir WWTPs NPDES Permit became effective February 1, 2000. The facility is
permitted to discharge 0.0864 MGD treated water from an on -site groundwater remediat on
system to an unnamedtributaryto Steele Creek. The current permit will expire on January 31,
2005.
The facility is comprised of the following components: extraction wells, submersible
pumps, surge tank, air stripper, particulate filter, and flow meter. The AquAir WWTP facility
received approval from DWQ to remove the liquidphase carbon absorption component from the
treatment works in March 2001. Documentation of this facility modification is maintained in
DWQ's facility file.
RECORDS/REPORTS:
DMRs and niaintenance records from September 2002 through August 2003 were
reviewed during the inspection. facility records and reports appeared to be well organized ized
were readily available. One deficiency in record keeping was noted, as follows,
1. The DMR dated February 2003 indicates that compliance samples were collected on 2/13,
however, results were reported as if collected on'2/1 . The DMR indicates that no
personnel were on site on 2/15 to collect samples. The DMR should be amended to
accurately reflect the sampling date and results, and resubmitted to NODE .
AIING: Marginal
FACIUTY SITE
The treatment system was not discharging when MCWP personnel arrived for the
inspection; however, the ORC reported that all components were operational and subsequently
reset the system components of the treatment system appeared to be operating properly and
the effluent discharge was observed. A locked gate and fence surround the facility, providing
controlled access. All compliance samples continue to be collected at a designated post -treatment
sampling valve.

FLOW ENT:
Both influent and effluent flow are continuously monitored using computer -based
technology (Signet vortex flow meters). The monitoring equipment is inspected for residue and
cleaned approximately every 6-months. Facility records indicated that flow meters were last
serviced on February 10 2003 and the ORC reports that service is scheduled again in the next few
weeks.
EFFLUENT/RECEIVING ATE'
The facility discharges to an unnamed tributary of Steele Creek, which is a Mass C water
in the Catawba River Basin. Effluent discharged from the system during g the inspection appeared
to be clear and odorless. The tributary appeared to be flowing normally under ambient conditions
d no effluent impacts in the receiving water were discernible.
SELF -MONITORING PROGRAM:
Facility effluent monitoring appeared to be consistent with permit requirements with the
following exception.
1. The DMR dated December 2002 indicated that laboratory hold -times were exceeded for
samples collected. on December 18. An attached letter from Face Analytical (the contract
service laboratory) indicates that a laboratory equipment failure resulted in broken hold -
times for samples that were analyzed under EPA Method 8260. This constitutes one (1)
failure to monitor for each of the nineteen (19) required VOC parameters. The December
DMR correctly identified the non -compliant facility status.
Facility effluent analytical results were reported to be within permit limitations with the
following exception.
1. The DMR dated April 2003 indicated that the facility failed to "Pass" the Chronic Toxicity
test for samples collected on April 8 and April 11. This constitutes one (1) violation of
the subject permit. The April DMR correctly identified the non -compliant facility status
d subsequent monitoring was completed per the permit requirements.
Two other deficiencies in monitoring were observed during the period of review. Both
deficiencies were related to compliance sample collection, as follows.
2. The DMR dated. September 2002 indicates that compliance samples were collected on
9/23, when flow was reported at 0.1623 MGD. This represents flow in excess of 10 times
the monthly average.

v
SELF -MONITORING PROGRAM (Continued). -
The DMR dated November 2002 indicates that compliance samples were collected on
1 Ill 1, when flaw was reported at 0.0000 MGD.
Compliance samples should be collected at a time when the discharge is characteristic of
the entire period that the sample represents.
TING: Unsatisfactory
OPERATIONS & MAINTENANCE:
Overall operation. and maintenance strategies appeared appropriate for the facility. The
grounds and buildings appeared to be well maintained and good housekeeping practiceswere
apparent.

notification of permit noncompliance. Shield reported the noncompliance to you by telephone
on July 16, 2004.
InJune, flow from asecond recovery well was added to the treatment system. Preliminary

An alytieal results of the late June sampling event received on July 16, 2004 confirn-led that the
efiluent had exceeded the discharge limitation of t],,re permit. Carbon tetrachloride was detected
this time at 140 ppb, again the permitted level is I 5.6'ppb, Tetrachtoroethene was detected at 61
ppb, and the permitted level is 31.3 ppb.
In early July, 2004, the control panel for the treatment systern had a power SLIT&N! Most likely
frorn recent lightning qorms, The RTU (Remote Telemetry Unit) was not communicating with
the CPU (Central Processing Unit). For this reason and more importantly because the effluent
exceeded the permit limits. the system currently has been left oil'.
"I"o address, the effluent limitations, Shield plans to re -install the activated carbon treatincrit
portion of the system or use an alternate Inter media, Carbon filters were eliminated by a March
21, 2000 NPDES Permit Modification. Therefore, we will have to prepare an Amendment to the
NPDES permit.

Shield is obtaining quotations for the reactivation of the carbon portion ofthe treatment system
or the usage of an alternate filter media, Shield is also waiting on repair parts and reprogramming
by an electrical controls technician. After the filter system is on-line and the controls portion of
the system is fixed, we will re -start the systern.

Re Notification of Noncompliance of Permit Limit
Former AquAir Facility
13300 Sam Neely :Road
Charlotte, Mecklenburg County
Permit # NCO0 6673
Shield Project # 104002-02
Dear Mr. Lesley.
n accordance with the National Pollutant Discharge Elimination System ( DES) Permit
#NC0086673 Section E Paragraph 9, Shield Engineering, Inc. (Shield) is submitting written
notification of permit noncompliance. Shield reported the noncompliance to you by telephone
on July 16, 2004.
In June, flow from a second recovery well was added to the treatment system. Preliminary
results of mid -June effluent sampling received in early July showed carbon tetrachloride
exceeding the maximum discharge limitation of the permit, The permitted level is 15.6 parts per
billion (ppb) and the level detected was 26 ppb. The new recovery well RW-2 is near the source
area and not surprisingly is probably producing more contaminated groundwater, which overall
will help with the cleanup. The results from sampling conducted in late June were pending,
Analytical results of the late Tune sampling event received on July 16, 2004 confirmed that the
effluent had exceeded the discharge limitation of the permit. Carbon tetrachloride was detected
this time at 140 ppb, again the permitted level is 15.6 ppb. Tetrachloroethene was detected at 61
ppb, and the permitted level is 31.3 ppb.
In early July, 2004, the control panel for the treatment system had a power surge most likely
from recent lightning storms. The RTU (:Remote Telemetry Chit) was not communicating with
the CPU (Central Processing Unit). For this reason and more importantly because the effluent
exceeded the permit limits, the system currently has been left off
To address the effluent limitations, Shield plans to re -install the activated carbon treatment
portion of the system or use an alternate filter media. Carbon filters were eliminated by a March
21, 2000 NPDES Permit Modification. Therefore, we will have to prepare an Amendment to the
DES permit.

Shield is obtaining quotations for the reactivation of the carbon portion of the treatment system
or the usage of an alternate filter media. Shield is also waiting; on repair parts and reprogramming
by an electrical controls technician. After: the filter- system is on-line and the controls portion of
the system is fixed, we will re -start the system.
If you have any questions or comments please contact the undersigned individuals.

Dear Mr. Gilchrist:
This is to inform, you that a review of your toxicity self -monitoring report form for the month of
April 2003 indicates a violation of the toxicity limitation specified in your ICES Permit.
You should take whatever remedial actions are necessary to eliminate the conditions causing the
effluent toxicity violation(s). Your efforts may include conducting a Toxicity Reduction Evaluation
(T ) which is a site -specific study designed to identify the causative agents of effluent toxicity, isolate
the sources of toxicity, evaluate the effectiveness of toxicity control captions, and then confirm reductions
in effluent toxicity. Please be aware that North Carolina General Statutesprovide for assessment of civil
penalties for violations of NPDES permit limitations and requirements.
The reverse side of this Notice contains important information concerning your Whole Effluent
Toxicity Monitoring and Reporting Requirements. Please note updated mailing addressesfor submitting
;your Discharge Monitoring Reports (D s) and Aquatic Toxicity (AT) Test Forms. We encourage you
to review this information and if it would be helpful to discuss this; situation or passible solutions to
resolve effluent toxicity noncompliance, please contact Mr. John Lesley with this office at (704) Cana-

S&ME Project No.. 13 4-q7-1758
Dear Mr, Bridgeman.
On behalf of the SNL Corporation, ME, Inc. is submitting this response to the Notice of
Deficiency letter dated January 28, 2003 for the Aquair WWTP in Mecklenburg County, North
Carolina. The AuAir WWTP is operated to treat groundwater recovered from the site prior to
discharge to the unnamed tributary located on site.
In response to the noted deficiency under Records/.Reports, S&ME is attaching the amended
Effluent Reports (DWQ Form MR- 1.1) from September 2001 to August 2002 with the corrections
detailed by Mecklenburg County Water Qualify Program (MC QP). The analytical laboratory
estimates of constituent concentrations below established minimum detection limits (DL) have
been changed to display "<MDL" on the re -submitted monthly NP'DES reports as per the requests
of MCWQP and NCDENR Division of Water Quality. Although the period of record review was
from September 2001 to August 2002, the same deficiency occurs on the Effluent Reports
submitted for September 2002 to November 2002. As a pre-emptive measure, S&ME is also
submitting the amended Effluent Reports for the period of September 2002 to November 2002.

Response to Notice of Deficiency E Project No. 13 4- 7-17
AauAir WWTP NPDES Pern-tit No. NC006673 FebruaU 13 2003
The facility will continue to submit monthly effluent reports as required by NPDES Permit No.
NC008667
Under the Se Monitoring Program category, the Notice of Deficiency lists a "marginal" „ rating for
our sample location of system discharge from a valve located inside the facility structure positioned
after the treatment system. However, the Se Monitoring Program category of the Notice of
deficiency also states "So as lone as the current sample location is totally post -treatment, the
location is acceptable." Since the valve located inside the facility structure has been deemed
acceptable, samples will continue to be collected from the valve. All field personnel will be
instructed to use the valve only to the extent that the valve remains post -treatment.
If further explanation is needed in response to the Notice of Deficiency, do not hesitate to contact us
at (704) 23-4726.

GEXE7L-.:
The AquAir WWTP facility began operation in November 2000. The Mecklenburg
County Wafer Quality Program (MCWQP)'conducted the original facility inspection on October
15, 2001. A Compliance EvaluationInspection report was issued on November 8,2001.
PERMIT:
DES Permit NCO086673 was issued to AquAir WWTP on December 20,1999 and
became effective February 1, 2000, The facility is permitted to discharge 0,0864 MC 'treated
water from an on -site Groundwater Remediation system into an unnamed tributary to Steele
Creek in the Catawba River Basin. The current permit will expire on January 31, 2005.
The supplement to the Permit Cover Sheet indicates that the facility is comprised of the
following components: extraction wells, submersible surge t
pumps, ,air stripper, particulate
filter, liquid phase carbon adsorption, and flaw meter, As noted in the previous inspection, the
AquAir WWTP facility received approval from DWQ to remove the liquid phase carbon
absorption component from the treatment works in March 2001. Consequently, the current
permit's description of the facility remains incorrect. Documentation of this permitted deviation
is maintained in DW }'s Facility file.
RECORDS/REPORTS:
All facility records and reports reviewed during the inspection appeared to be well
organized and easily accessible. However, during MCWQP's in-house I file review for the
period of September 2001 through August 2002, several DNIR reporting deficiencies were noted.
Specifically, analytical laboratory estimates below established MDLs, without benefit of low
range standards, should be reported as " L". For example, if the MDL is 10 u, L, then the
value reported would be <10 ug/L. MCWQP provided detailed descriptions of the noted
deficiencies to S&ME representatives. Although none of the reporting deficiencies appeared to
be related to overall facility operation or discharge, in that no permit violations were noted,
amended 1CMRs should be submitted to the DWQ.

FACILITY SITE REVIEW:

in the Catawba River Basin. All of the permitted equipment appeared in place and serviceable,
All equipment was reportedly functional but no effluent was discharged during the inspection.

FACHATY SM REVIIEW:
The facility discharges to an unnamed tributary of Steele Creek, which is a Class C water
in the Catawba River Basin. All of the permitted equipment appeared in place and serviceable.
All equipment was reportedly functional but no effluent was discharged during the inspection.

C
FLOW MEASUREMENT:
AquAir WWTP's current NPDES permit requires continuous, recording flow monitoring
o either the influent or the effluent. The facility employs computer -based tchnolo
vortex flow meters} to monitor both influent d effluent flow. The monitoring equipmentgy riet
inspected for residue and cleaned every 6-months, flow information is recorded continuously.
EFFL NT t E G WATERS:
The facility discharges to an unnamed tributary of Steep Creek, which is a glass C water
in the Catawba River Basin. No effluent was discharged from the system during the inspection;
therefore, no evaluation ofrepresentative effluent was conducted. However, recent rain elevated
stream stage in the receiving tributary, causing increased flow and turbidity. This appeared to b
a natural condition uninfluenced by the facility operations.
SELF -MONITORING PROGRAM. -
Parameter monitoring frequencies at the facility were consistent with permit
requirements. The NPDES permit identifies Outfall 001 as the required sample collection
location, Samples are currently being collected from a valve, located inside the facility
structure. So long as the current sample location is totally.: post -treatment, the location is
acceptable.
RATING, marginal
OPERATIONS N & MAINTENANCE:
Overall operation and maintenance strategies appeared appropriate for the facility, in that'.
the grounds and buildings appeared to be well maintained. Good' housekeeping practices were
apparent. A lockable gate and fence surround the somewhat isolated facility structure, providing
adequate access control and security,
