RE: REQUEST TO RESCIND PERMIT
NPDES PERMIT NO. NC 0085821
TYCO ELECTRONICS BUILDING 42 — CHURCH STREET
GREENSBORO, NORTH CAROLINA
Dear Mr. Weaver:
Tyco Electronics originally applied for the NPDES permit to authorize the discharge of
treated groundwater at this groundwater remediation site. For several reasons, we have
not ever discharged under this permit and in fact, the piping necessary for a discharge
under this permit has never been installed.
The permit expires on August 31, 2005. We do not wish for the permit to be renewed
and thus will not be submitting an application for renewal. Please allow the permit to
expire on August 31, 2005, or if more convenient for the Department, you may rescind
the permit at an earlier date.
If you have any questions regarding this request, please contact me at [phone].

Subject: NPDES Permit Modification Request
Permit No. NCO085821
Dear Mr. Foster:
This letter is to confirm our understanding regarding your intent to modify the carbon filters in the
groundwater remediation system at your Greensboro facility, and to insure that Tyco is aware of the Division's
position in this matter.
Per your letter dated September 12, 2003 and two telephone conversations with Dawn Jeffries of the
NPDES Unit, we understand that one of the 1000 lb. carbon filters in your groundwater remediation system has
developed a leak, and the system has been down for several months.
You desire to repair the system by replacing the leaking filter with one of lesser capacity, as you feel that a
smaller one would be sufficient. You understand that this will require an Authorization to Construct (ATC) permit
and intend to submit the appropriate paperwork to get that authorization as you do want to maintain your permit to
discharge in the event that you need it in the future.
However, you wish to begin remediation again as soon as possible, and feel that a delay of several more
months (to get the ATC) would not be advisable. Therefore, since you are not currently discharging under the permit
but into a municipal sewer, you intend to replace the filters and begin water treatment promptly. You understand that
you may not discharge into surface waters under your current permit until modifications to it are approved by the
division.
This request is very unusual, but we are willing to accommodate it. Please understand that this course of
action entails some level of risk to you. We cannot guarantee that the application for an ATC will be
approved as requested. Also, if you should need to discharge under your NPDES permit in the interim, you
could not.
If you have any questions concerning this letter, please call Dawn Jeffries at telephone number (919) 733-
5083, ext.595.

RE: NOTIFICATION OF SYSTEM MODIFICATION
NPDES PERMIT No. NC 0085821
TYCO ELECTRONICS BUILDING 42 —CHURCH STREET
GREENSBORO, NORTH CAROLINA
Dear Ms. Jackson:
Per our consultant's conversation with Ms. Valerie Stevens of the NC-DENR Division of
Water Quality on 13 August 2003, Tyco Electronics Corporation is submitting this letter
to notify the NC-DENR Division of Water Quality of a proposed groundwater treatment
system modification for the above referenced site (NPDES Permit No. NC 0085821).
The purpose of this letter is to detail the proposed modification to the groundwater
remediation system operating under the referenced NPDES permit.
The site currently operates a groundwater pump and treat system consisting of two (2)
recovery wells, two (2) bag filters, an equalization tank, two (2) air stripping towers in
series, and two (2) carbon filters in series for final polishing prior to discharge. The
system currently discharges treated water on -site into the POTW sewer system. The
treatment system maintains a NPDES Permit allowing discharge into an unnamed
tributary of Buffalo Creek; however, the discharge pipe has not been connected and the
system has not yet discharged under the NPDES Permit. On 05 May 2003 the system
was shutdown because a leak had formed in one carbon canister, allowing the carbon
and treated water to escape from the system. The system has remained shutdown
since 05 May 2003 because of the compromised carbon vessel and because the site
has been undergoing substantial development and the remediation system was not
accessible until last month.
The treatment system utilizes the carbon vessel for the final polishing of the treated
water in the event of the reduced performance of the two (2) existing air strippers.
Based on site access and logistics, Tyco Electronics proposes to replace the permitted
dual series 1000 lb. Granular Activated Carbon (GAC) filters with three (3) Carbtrol HP-
200 canisters in parallel. The canisters will be filled with 200 lbs. of reactivated carbon
(Iodine Average of 1000) for a system total of 600 Ibs with five (5) minutes of carbon
contact time. Historical sampling data from after the 2nd air stripper (42-EFF-1, prior to
the carbon canisters) is provided in Table 1 (following text). Since 1998, there have only
been three monthly samples (4/00, 7/02, and 3/03) in which Volatile Organic

Ms. Christie Jackson
Page 2
September 12, 2003
Compounds (VOC's) were detected in the samples collected after the 2"d air stripper.
Based on this historical information and the low levels of VOC's detected in these three
samples (2.0 pg/L, 1.0 pg/L, and 1.4 pg/L), the proposed system modification of the
three (3) Carbtrol HP-200 canisters in parallel will provide adequate carbon contact time
for final polishing of the treated water in the event that the extracted groundwater is not
completely treated by the two (2) existing air strippers. Historical sampling data following
the previous carbon canisters (42-EFF 3) is also provided in Table 2. As detailed in
Table 2, all groundwater constituents monitored in accordance with applicable discharge
permits have been Non -Detect (ND) or Below Quantifiable Limits (BQL) following the
carbon canisters. Please note that on April 24, 2000, chloromethane was detected in
effluent samples from both the air strippers and the carbon canistersat 2 ug/I; however,
this constituent has not historically been detected in groundwater samples and is
considered to be an anomaly or laboratory artifact.
The Carbtrol HP-200 canisters (rated at 10 GPM, 75 PSI each) will function in parallel
allowing the processing of 30 GPM. Based on historical system readings, the system
Column #2 (2"d air stripper) discharges at an average "instantaneous" flow rate of 30
GPM and at an average "instantaneous" 30 PSI line pressure before the carbon unit,
therefore the proposed modification of the system will enable the system to effectively
process the same volume of water with same line pressure as the present configuration
of dual carbon vessels. In essence, the proposed three (3) Carbtrol HP-200 canisters in
parallel will collectively function in equal magnitude of water processed and treated as
the current dual GAC canisters. Please note that we are not requesting a change to the
flow rate specified in the current permit (28,000GPD or 19.4 GPM).
Pending approval of the treatment system and NPDES Permit modification by NC-DENR
Division of Water Quality, Tyco Electronics proposes to modify and restart the treatment
system on or before 30 September 2003 unless otherwise notified.
If you have any questions regarding this notification, please contact me at (717) 986-
7916.

Subject: Issuance of NPDES Permit NCO085821 and
Issuance of Authorization to Construct
TYCO Electronics Corporation / Greensboro
(formerly AMP, Inc.)
Guilford County
Dear Mr. Foster:
Division personnel have reviewed your permit modification request and your request for an Authorization to Construct
Accordingly, the Division is forwarding herewith the subject NPDES 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 May 9, 1994.
On November 18, 1999, the Division received comments submitted by Harding -Lawson Associates (HLA) regarding the
draft NPDES permit for this facility. The final permit reflects the changes made after review of HLA's written comments as well
as any changes based on subsequent discussions between Division personnel and HLA personnel. This permit also approves
relocation of the effluent outfall from an unnamed tributary to North Buffalo Creek to North Buffalo Creek.
After further consideration, the Division has approved the request to reduce (from monthly to quarterly) the monitoring
requirements for the volatile organic parameters of concern (VOCs). Although TYCO Electronics Corporation has not yet
submitted effluent discharge data collected under an NPDES permit, data from the treatment system was available and sufficient
to resolve this issue. The data verified that VOC levels have been below detection level. It is not expected that VOC levels will
rise during this permit cycle, as the current treatment system has been active for several years. However, should VOCs be found
in detectable levels during this permit cycle, the Division will likely increase the monitoring frequencies for VOCs. Additionally,
whole effluent toxicity testing is still required and should coincide with the monitoring for the VOCs.
The lead limit implemented in this permit represents 1/2 the final acute value at a hardness of 50 mg/L and is based on
total lead Instead of dissolved lead). This limit protects instream aquatic fife from any acute effects that may be caused by the
discharge of lead in the effluent. No dilution calculations are required for this implementation method. Additionally, a reasonable
potential analysis (RPA) was performed on the existing monitoring data for lead. The RPA indicated that there was a reasonable
potential for violation of the instream standard [ref. EPA's Technical Support Document for Water Quality -based Toxics
Control].

This permit also grants an Authorization to Construct (ATC) for the approximately 1700-foot effluent force main,
flow meter, and all other appurtenances associated with relocation of the effluent outfall to North Buffalo Creek. The existing
effluent pump (rated at 20 gpm, 31 ft. TDH) will remain in use as the outfall pump. After construction tinder this ATChas
been completed and an Engineer's CerdLcare (enclosed with thispermit) has been submitted, the permitree is
authorized to operate with the approved design components.
This ATC is issued in accordance with Part III, Paragraph A of NPDES Permit NCO085821 (attached). This ATC shall
be subject to revocation unless the wastewater treatment facilities are constructed in accordance with the conditions and
limitations specified in the permit. A copy of the approved plans and specifications shall be maintained on Ale by the
Pennittee for the life of the facility. The issuance of this ATC does not preclude the Permittee from complying with any and
all statutes, rules, regulations, or ordinances which may be imposed by other government agencies (local, state, and federal) which
have jurisdiction.
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) days following receipt of this letter. This request
must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the
office of Administrative Hearings, 6714 Mail Service Center, Raleigh, NC 27699-6714. Unless such a demand is made, this
permit shall be final and binding.
Please take notice that this permit is not transferable except after notice to the Division of Water Quality. The Division
of Water Quality may require modification or revocation and reissuance of the permit.
This permit does not affect the legal requirements to obtain other permits which may be required by the Division of
Water Quality, the Division of Land Resources, the Coastal Area Management Act, or any other federal or local governmental
permit.
If you have any questions concerning this permit, please contact Susan Wilson at telephone number [phone], ext.

Harding Lawson Assoc./ Consultants
Consultant requested modification of the permit on behalf of AMP to relocate the outfall
and to reduce Some monitoring requirements. Also submitted plans and specifications
for the outfall relocation from UT to North Buffalo Creek. Additionally, requested change
in permitted flow based on available flow data.
The site has been active since 1988 and AMP first requested a permit in 1996.
Monitoring data included most parameters that were found in detectable levels in the
monitoring wells. 5ome inorganic monitoring was required. Chlorinated solvents were the
primary contaminants. Part of the facility's flow went to the City of Greensboro and
part went to a subsurface system. Greensboro is cutting the GW flow off and the
subsurface system cannot take the entire remediation amount, so the NPDE5 discharge
is needed.
The proposed discharge location has a 7010s = 0.049 cfs, Qavg =12.9 cfs (per C.
Weaver, U5G5). This corresponds with flows at 0209518100, IWC is 5.4%.
The requested flow is 0.0286 MGP (reduction from 40 gpm to 20 gpm).
The subsurface system was approved via W00004491 at 0.0576 (2 galleries at 28,500
gpd). The treatment units (equal. Tank, 2 air strippers, 2 carbon filters, and flow meter)
are already in place and assumed approved via the WQ permit. 5ubmitted monitoring
data show no levels of detection with the exception of lead.
The draft permit reflects monitoring for the POCs that are primary contaminants and
the inorganics that were in the previous permit (and had not been monitored). A lead
limit was placed in the permit which reflects'/2 FAV, a reasonable potential analysis was
Performed which showed the need for a lead limit. 5ome parameters were eliminated due
to having no presence in the effluent to the city/ subsurface system.
The consultant requested that the VOCs that are primary contaminants be reduced to
quarterly due to their lack of presence in previous monitoring data. The revised permit
reflects this request [the site has been active for several years and no detect levels
were shown for those parameters].
this permit also reflects an ATC for the force main for the relocation. 51nce this force
main is not technically a "sewer" it does not have to conform to all the stipulations
presented for a pump station force main at a collection system. The ATC was given a
cursory review [consultant presented calculations which were adequate].

Glen,
Jason Prosser (HL&Assoc.) sent me your e-mail address because I wanted
to let you know how we were going to proceed with issuance of the AMP
permit. Unfortunately, due to our backlog level (which EPA tracks,
etc.) we can no longer "hold" this permit. I need to send this up to my
supervisor for issuance. Because AMP is still in the decision making
process as far as further action on this discharge, this is the way I'd
like to present this permit:
Issue the permit with both the existing location and the relocation
noted and with limits/monitoring to reflect each (previously, DWQ only
presented limits/monitoring for the relocation). Should AMP choose not
to relocate or find there is no need for an NPDES discharge, AMP can
inform the Division in writing at a later time.
Also, should AMP provide convincing information that the acute lead
limit is not appropriate, AMP can present that information and DWQ will
review at a later time. We'll work with AMP on any issue as best as
possible. I'll also revise the expiration date to 5 years ( because the
existing expiration date was set at June 30, 2001 to correspond with
other permits in the river basin).
Sorry for the push on this one, but DWQ has been patient and the
previous consultant, (prior to Jason Prosser who has been extremely
helpful and cooperative), was continually pushing us to move on the
permit (and I've essentially held this for 7.months after it's been
ready to issue). Thanks for your time.

Unfortunately, we need a representative from Tyco to fill out the name change form
(don't know when this took place, but we could have gotten this done earlier had I
known). Sorry for any delays.
As for the lead limit, as I indicated in the previous Fax, the lead limit is based on an
acute value (1 /2 FAV). NC uses a hardness of 50 mg/I (this could be the reason you
are not getting similar values) and also uses a limit based on a total (not a dissolved as
EPA criteria indicate). Due to only 2/month sampling, we implemented a daily
maximum based on this acute value of 33.8 ug/I.
The calculation to derive the acute value of 33.8 ug/I is exp(1.273(ln(hardness)) + (-
1.460)), the constants being taken from EPAs derivation equations. Ref. Federal
Register publication 4/22/99 (FRL-6330-2), EPA, National Recommended Water Quality
Criteria.
I'll be out next week, but someone else in the NPDES unit may be able to help you if
you have further questions about the name change.
Have a good holiday.

RE: Comments to Draft NPDES Permit
AMP lucorporated, 1126 North Chureb Street
Greensboro, Guilford County, NC
Permit No. NCO085821
Dear Mr. Goodrich:
We have reviewed the draft NPDES permit and offer the following comments. For your convenience,
applicable text from the draft permit and cover letter is included with our comments. Also, please note
that AMP Incorporated has changed their name to Tyco Electronics Corporation, which we request be
reflected in the NPDES permit.
DWQ Cover Letter: Because the other volatile organics (i.e., chlorinated VOCs) are primary
contaminants and parameters of concern, they have been included in this draft to be monitored on a
monthly basis. A reduction of the monitoring frequency may be requested upon completion of 12
months of sampling under the NPDES permit. This can be done as a minor permit modification.
Cownent., Inorganic and certain organic parameters were removed from the draft permit because
they were not present in the submitted effluent data. Similarly, chlorinated VOCs are not present in the
effluent; no additional sampling is necessary to determine the monitoring frequency. Chlorinated VOCs
are the groundwater constituents of concern and have been the focus of remedial efforts at this site for
years under the jurisdiction of the Groundwater Section. The treatment system effluent has been
monitored for these VOCs for over 10 years with no observed detections. These data have been provided
to the DWQ Winston-Salem Regional Office and the Central Office, and the City of Greensboro
Pretreatment Coordinator. In addition, a summary of these data for the last year of monthly VOC
monitoring was included in the permit modification request. These data clearly indicate that no
chlorinated VOCs have been detected in the effluent_ This -in icates that the treatment system is
extremely reliable and the VOC removal efficiency is 00 perce t. One additional year of monthly $ ouaD Ii5
monitoring will not provide the NPDES Group any better data to evaluate our request Tyco Electronicsa- 'AE r
Corporation believes there are sufficient data that support the request for a quair erly monitoring
frequency and we ask the NPDES Group to reevaluate the monthly monitoring frequency included in the
draft permit.
In addition, the influent VOC concentration has decreased substantially over the last 10 years; and
therefore, the treatment system VOC loading has been very much reduced. There has been a 96 percent
reduction in the influent concentration, and as 88 percent reduction in the VOC mass loading to the .

treatment system. Because of the success of the groundwater remediation program and the reduction in
the influent constituents, the treatment system is expected to function even more efficiently.
AWQCover Letter: Arsenic, chromium, copper, iron, manganese and zinc monitoring have been left
in the permit due to lack of data to eliminate. Upon initial review and development of the permit, these
parameters were shown at levels above detection in monitoring well data. Although these parameters
may not be primary contaminants, they may be present in the effluent in amounts approaching allowable
levels. As stated above, monitoring frequency may be reduced or eliminated after the collection of 12
months of data.
Comment: The metals listed above are common naturally occurring constituents in soil typically
observed at concentrations of I to over 100 m&1Xg. No releases of these Constituents occurred at this site
and therefore they arc not contaminants of concern, and have not have been monitored routinely.
Because the groundwater treatment system is a pump and treat -type system, soil particles, on occasion,
may be pumped out of the subsurface with groundwater and the constituents may be observed to an
analysis of groundwater.
Because the constituents are naturally occurring Tyco Electronics Corporation believes that no ol�
additional metals testing is necessary. however, because there is limited effluent metals data, we will
collect monthly data for a year and then request any appropriate changes in the permit.
AWQCover Letter and Permit .Lindmions: Lead has been limited due to its presence in existing �Je tN
data and the monitoring frequency is 2 per month.
Cormnent: Similar to the above listed metals, lead is another very common naturally occurring
metal in soil; typical concentrations range between I to 300 mg/Kg. No release of this constituent
occurred at this site and therefore lead is not a site contaminant of concern. However, effluent lead has
been monitored monthly as a requirement of our existing pretreatment permit with the City of
Greensboro. A summary of the data submitted to the POTW was included in the permit modification
request (repeated here as Table 1). These data are not substantially different than the data used to
develop the original NPDES permit (Table 2), which includes a monthly monitoring frequency with no
specified lead limit. Tyco Electronics Corporation does not agree that, based on essentially the Samee�
data, a more aggressive sampling frequency with a specified limit on a naturally occurring constituent is/ No
warranted.
As suggested, we are currently initiating analyses of total and soluble lead to assess the concentration uN'^ is
ok5cD oN
and form of lead that may periodically exist in the influent and effluent. We do not believe that theme
current data is sufficient to establish an effluent limitation for lead. As an alternative to the draft permit
requirements, we propose to collect monthly samples of the influent and effluent, analyze these samples_ 4 e o >
for total and soluble lead, and submit the results to the DWQ. The data can then be used to determine if
a permit limit is warranted and, if necessary, to develop methods to reduce lead from entering the
treatment system. The first effluent sampling event for total and soluble lead was conducted last week
(November 10, 1999). The concentration of lead in both the total and soluble analyses was below the
quantitation limit (BQL).

Mike,
Give this a once over. Nothing out of the ordinary. Eliminated some requirements based
on submitted data. Added lead limit due to some data above 1/2 final acute value.
Couldn't eliminate other metals requirements due to no previous data. 7Q10 increased
from 0.0 cfs to 0.49 cfs, so toxicity % reduced to 8.4% (also because flow requested
reduced to 0.0288 MGD).

RE: . Additional Requested Steam Information
NPDLS Permit Modification and Authorization to Construct
AMP Incorporated, 1126 North Church Street
Greensboro, Guilford County
Permit No, NTCO085821
Dear Ms. Wilson:
In May 1999, AMP Incorporated (AMP) requested Authorization to Construct (ATC) a new effluent
discharge line and a modification to the NPDHS Permit for their Church Street site groundwater
treatment system (Pemtit No. NC0085821). The requested ATC and N'PDES permit modification is for
relocation of the current discharge point, an unnamed tributary to North Buffalo Creek, to a new
discharge point at North Buffalo Creek. The new discharge location is approximately 1,500 lineal feet
downstream from the current location. No other structural modifications are requested.
We spoke last week regarding the status of your review. During that conversation you requested
additional information on the proposed discharge stream; particularly the drainage area used to calculate
the new Instream Waste Concentration (IWC). As indicated in the permit modification and ATC request,
Mr. Curtis Weaver, Low Flow Stream Analyst, USGS, was contacted to estimate the proposed discharge
stream drainage are and 7Q10 £low, Mr. Weaver estimated that the drainage area at the proposed
discharge point, the confluence of North Buffalo Creek and the unnamed tributary is 14 square miles.
The resulting low flow estimate provided by Mr. Weaver is 0.49 cfs. The following tables summarize
the information provided by the USGS and our resulting calculation of the new IWC.

Subject: Additional Information Request
Permit Modification
AMP Inc- Groundwater Remediation
NPDES Permit No. NCO085821
Guilford County
A letter of request for a permit modification. along with supporting documentation, was
received May 15. 1999 by the Division of Water Quality and has undergone an initial review.
Because the modification request involves relocation from an unnamed tributary to the
mainstem of North Buffalo Creek, the Division considers this request a major permit modification
which must be publicly noticed in the regional newspaper. Additionally, a major modification request
of this permit is subject to an administrative Lee of 5215.00 This was discussed August 10, 1999 with
Mr. Jan Smith of Harding Lawson Associates. The Division apologizes for any initial confusion
regarding the required fee.
AMP has also requested in this modification that monitoring for certain parameters be
eliminated. Multiple data for organic parameters and lead was included with the modification request.
However, AMP also requested elimination of other inorganic and metal parameters. If AMP has data
available for those constituents (taken at the effluent or at any of the monitoring wells), that data
would potentially support removal of those parameters and expedite the modification request. Those
inorganic parameters were required initially due to the detection of them in the facility's groundwater
monitoring tests. Please compile and submit any effluent or other data which may support your
request. Total suspended solids and ofl/grease will be removed from the permit as these parameters
are not expected to be present with the treatment provided.

RE: NPDES Permit Modification and Authorization to Construct
AMP Incorporated, 1126 North Church Street
Greensboro, Guilford County
Permit No. NCO085821
Dear Mr. Goodrich:
AMP Incorporated (AMP) hereby requests Authorization to Construct (ATC) a new effluent discharge line
and a modification to the NPDES Permit for our Church Street site groundwater treatment system (Permit
No. NC0085821). The requested ATC and NPDES permit modification is for relocation of the current
discharge point, an unnamed tributary to North Buffalo Creek, to a new discharge point at North Buffalo
Creek. The new discharge location is approximately 1,500 lineal feet downstream from the current
location. No other structural modifications are requested.
It is our understanding these modifications are minor and, at this time, no formal application or fee is
required.
AMP also would to like notify the NPDES Unit that we have retained Harding Lawson Associates (HLA)
to serve as our engineering and technical consulting representative for design and construction of the new
discharge line and implementation of the NPDES permit modification. All technical questions should be
directed to Mr. Jan Smith, P.E. of HLA. He can be reached by telephone at [phone].
Proposed Structural Modifications
The treatment system is located at 1126 North Church Street in Greensboro, North Carolina. The
treatment system consists of a series of groundwater extraction pumps and piping that transport
groundwater to a small treatment system. The treatment system consists of an influent holding/equalization
tank, two in -series air stripping towers, two in -series carbon vessels, and in -plant pumps, flow meters and
appurtenances. The current flow is approximately 9 gpm (13,000 gpd). Mr. Don Geddes of the DWQ-
Groundwater Section, Winston-Salem Regional Office has been the case manager for this site for a number
of years and is very familiar with the treatment system and the history of the site. In addition to Jan Smith,
Mr. Geddes should be contacted if you have any questions regarding the operations of the treatment system.
The proposed modification includes changing the permitted effluent discharge point from an unnamed
tributary to North Buffalo Creek to North Buffalo Creek at the confluence of the same unnamed tributary.

Mr. David Goodrich
May 11, 1999
Page 2
Consequently, a new In -stream Waste Concentration (IWC) for chronic toxicity testing must be developed
based on the 7Q10 flow of the new receiving stream. A two-inch force main is proposed to convey effluent
groundwater to the new discharge point. The force main will tie into the existing pump station at AMP's
groundwater treatment system. The proposed alignment of the force main will parallel an existing City of
Greensboro storm sewer. The force main will be constructed within the City's storm sewer easement,
which has been approved by the City of Greensboro Department of Water Resources and the City
Attorney's Office. The approximate force main alignment is presented in the attached plan sheets. The
alignment will be verified during construction. The estimated future discharge flow (design flow) is 20
gpm (29,000 gpd), which is less than the current permitted flow.
Proposed Permit Modifications
Flow
The permitted flow is 0.0576 MGD (40 gpm). However, the current actual flow is 9 gpm and the
estimated future average flow is 20 gpm (0.0288 MGD). Therefore, AMP requests that the more accurate
estimated future flow of 0.0288 MGD be reflected in the permit.
Effluent Limitations —Monitoring Requirements and Frequency
The current permit requires monthly monitoring for a number of chemical parameters that are not
associated with the impacted groundwater at the site. The groundwater is impacted by chlorinated solvents
(tetrachloroethene, or PCE, is the primary constituent of concern), which are effectively monitored for by
EPA Method 601. Thus, AMP requests that chemical parameters not associated with the impacted
groundwater be deleted from the monitoring requirements. These parameters are Total Suspended Solids,
Oil and Grease, Benzene, Toluene, Arsenic, Chromium, Copper, Iron, Lead, Manganese and Zinc.
To support this request for deletion of these parameters, attached are Tables 1, 2-1, 2-2 and 2-3, which
summarize the results of monthly effluent monitoring for VOCs, BTEX, TPH and Total Lead for the last
12 months. Effluent VOCs are voluntarily measured on a monthly basis for internal operating control.
Effluent BTEX, TPH and Total Lead are measured as required by the pretreatment permit issued by the
City of Greensboro. As summarized in these tables, the monitored constituents are either not detected or, if
detected, at low concentrations below applicable water quality standards. Low levels of Total Lead have
been periodically detected because of the testing methods specified by the City (EPA Method 3030C);
which requires an unfiltered acidified sample that captures background lead from sediment.
In addition, no pH monitoring is specified in the current NPDES permit. If, during your review of the
pernut modification, pH is determined to be required, AMP requests that a pH range appropriate for the
background groundwater chemistry conditions be used. Background groundwater pH at the site ranges
from 5.3 to 8.1 (Table 3) and it is this background pH that influences the treatment system final effluent
pH. Therefore, if pH is required, AMP requests that a pH range of 5.0 to 9.0 be incorporated into the
modified permit.
AMP further requests that the monitoring frequency be reduced from monthly to quarterly. Because of the
low discharge volume and the simplicity and redundancy of the treatment train, AMP believes a less
rigorous sampling frequency requirement is justified. To support this request, attached are Tables 2.1, 2.2
and 2.3 which summarizes effluent data for the last 12 months. Ten years of similar data are on file with

effluent by Method 601 since 1989.
Need For The Modification
IWC and Chronic Toxicity Testing
Chronic toxicity testing was conducted during start-up of the treatment system prior to initiating a
discharge. The pilot testing demonstrated that the effluent groundwater discharge could not consistently
meet the limitations specified in the permit at the current discharge point. Consequently, AMP has never
used its NPDES Permit at this site.
In lieu of discharging to the unnamed tributary as specified in the NPDES permit the effluent was split into
two streams. A portion of the effluent is directed to the City of Greensboro sewer system under a
pretreatment permit, and a portion of the effluent is discharged back to the subsurface groundwater. Both
discharges are limited by the allowable flow. The effluent flow that is directed back to the subsurface
groundwater is at the maximum absorptive capacity of the on -site soils. The maximum allowable
discharge rate to the POTW, which is established in the pretreatment permit, is 10 gpm. The combined
capacity of these two discharge points is less than the expected future discharge flow.
In addition, because the treatment system effluent is clean groundwater, there is uncertainty in how long the
City will allow this discharge to take up useful capacity at their wastewater treatment plant. Thus, AMP is
seeking an alternative effluent discharge plan that uses our NPDES permit for its intended purpose.
However, because the current permitted receiving stream drains a very small sub watershed, the 7Q10 is
low and the resulting IWC is high (90%). Consequently, as described above, the effluent could not
consistently meet the permitted chronic toxicitylimitation.
Data.and Information for Modification Approval
For your information we have included a summary of the flow and water quality conditions at the new
discharge point. These data were obtained from interviews with state and federal personnel that the
NPDES Unit typically relies upon to complete their review. AMP calculated an IWC for the new discharge
location as well. The key personnel interviewed for this modification request included: Mr. Curtis Weaver,
Stream Low Flow Analyst, USGS; Mr. Kevin Bowden and Ms. Christy Robeson of the DWQ Aquatic
Survey and Toxicology Unit; Ms. Andrea Leslie of the Water Quality Planning Branch; Mr. Mike Mickey
of the Winston-Salem Regional Office; and several personnel within the NPDES Unit. The data and
information obtained include the following:
7QI0 and IWC
Curtis Weaver (USGS) was contacted to provide an estimate of the Summer 7Q10 flow conditions at the
proposed discharge point (the confluence of the unnamed tributary at North Buffalo Creek, see Figure 1).
Mr. Weaver reported that the estimated 7Q10 under natural flow conditions is 0.49 cfs. Based on the
7Q10 and AMP's estimated effluent discharge flow (20 gpm), the IWC is estimated to be 8.4%.
The IWC calculation was reviewed by Kevin Bowden and Christy Robeson. They confirmed the
calculation and the IWC based on the effluent flow data provided by AMP and the 7Q10 provided by the
USGS.

Stream Classification and Impaired Rating (303d List)
The proposed discharge point is located within a segment of North Buffalo Creek that appears on the 303d
list; thus, the stream segment has an impaired rating. In addition, the stream segment is in the Cape Fear
Watershed Basin and is classified as C NSW. Andrea Leslie was contacted to determine problem
parameters of the impaired segment. Ms. Leslie indicated that the problem parameters include fecal
colifomt bacteria and ammonia, and the biological community is impaired. According to personnel within
the NPDES Unit, these parameters are typical of municipal wastewater treatment plants and should not
impede the permit modification for an effluent groundwater discharge.
Winston-Salem Regional Office Comments
Mike Mickey of the NPDES Unit, Winston-Salem Regional Office indicated that he is familiar with the site
and treatment system and is not aware of any concerns that would impede the permit modification.
Three sets of plans and specification for the proposed force main and three sets of force main design
calculations are attached. Please contact the undersigned or Jan Smith of HLA if additional information is
required. We look forward to your favorable determination.

Z�In a letter to you dated September 29,1998, we advised you of our
Q-'4innterest in constructing and operating a pilot -scale constructed wetland
�i system at the AMP, Inc. site in Greensboro. The purpose of this pilot
3 project will be to demonstrate the feasibility of using a wetland process
co
for polishing treatment after an existing on -site ground water treatment
system and prior to discharge to a nearby stream via terms of the subject - t
NJ NPDES permit.
After several conversations with Paul Clark of your office, it is our
Runderstanding that we do not need a formal permit from your office to
I 'cbnduct the study outlined above. As a result of these conversations, we `^-CCU
o Qkagreed to prepare the following description of how we anticipate the
study will be conducted. We have deliberately not proceeded with any
v design activities until we advised your office of our intent and received
at least preliminary concurrence with our concept. Therefore, the
'11ollowing explanation will lack some details. On the other hand, we
Y think that there is sufficient information provided herein to give you a
good understanding of how we would conduct the study.
b -?The size of the pilot system will be dependent upon the size and shape of
q ` athe areas available on the site. Ideally, we like to use a minimum size of
• � 25 feet by 100 feet. Preparation of the test plot will consist of clearing
rand grading the test site into a relatively flat area. Only enough soils will
be excavated to create one to two feet high berms around the plot. The
Z, excavated soils will be used to construct the berms. Therefore, less than
Q ,one foot of cut is anticipated. If the finish grade soils are found to be
�imoderately or more than moderately permeable, powdered bentonite a`k
will be mixed into the top several inches of soil to create a low

permeability surface layer. After the test plot is prepared, it will be
planted with a mixture of several different types of vegetation, most of
which will be tolerant to wet soil conditions.
We plan to operate the system by taking a portion (ranging from 1 to 10
gpm) of the treated effluent from the existing ground water treatment
system and routing it to the test plot. We will start loading the plot at
relatively low hydraulic loading rates to allow the vegetation to grow
and to acclimate the naturally occurring microorganisms and the
vegetation to the treated ground water. After operating for a period of
time (typically two to four weeks) at a specific hydraulic loading rate, the
test plot effluent will be tested to determine whether it meets the
limitations of the current NPDES permit, including the aquatic toxicity
requirement. If the effluent sample meets the permit conditions, the
hydraulic loading rate will be increased. After another two to four
weeks, the effluent will be sampled and tested again. This process will
continue to the point where the effluent sample no longer meets the
permit conditions. This will establish the design loading rate for the full
scale system.
Our plan is to design the test plot so that the effluent flow from the plot
can be captured and directed to either the on -site infiltration trenches or
to the local POTW, both of which are currently permitted. The test plot
will also be designed to prohibit surface run-on from storm events and a
simple cover will be used to prevent rainfall from falling directly on to
the test plot. Thus, it is unlikely that there will be a need to discharge to
the receiving stream.
The length of time needed for testing is unknown at this time. Unlike
pilot systems using conventional technologies, the wetland test plot will
require time for the vegetation to establish itself. It will then take several
weeks under each loading rate condition for the system to become
acclimated to the increased loading rate. Finally, we cannot at this time
predict the maximum loading rate that can be used before the system no
longer performs satisfactorily. A study of this nature typically takes .
between nine months to a year to obtain sufficient data upon which to
base a full-scale design.

Subject: AMP, Inc. Site in Greensboro, NC
NPDES Permit No. VVQ0®94491--
Dear Mr. Goodrich:
/VCOO 858a IVia Fax: [phone]
AMP, Inc. is currently operating a ground water remediation system at
its Church Street Site in Greensboro, NC. Recovered ground water is
treated via air stripping and activated carbon. The discharge alternatives
for the treated ground water include (1) ground water recharge via on -
site infiltration trenches, (2) discharge to the local POTW, and (3)
discharge to an unnamed tributary via NPDES permit number
WQ0004491.
The on -site infiltration trenches have been found to have limited capacity
and, being in the central portion of the site, these trenches may limit
future development of the site. The local POTW has capacity limitations
and can take only a portion of the treated ground water flow. Therefore,
the NPDES discharge is becoming an increasingly favored alternative.
In order to provide an additional measure of treatment and protection
for meeting the NPDES permit requirements, we have suggested to AMP
that consideration be given to polishing the treated ground water with a
constructed wetland system. The wetland process could be installed on a
portion of the property that would be out of the way of future site
development and would receive treated ground water from the current
ground water treatment system prior to discharge to the unnamed
tributary. We have further suggested that a small pilot -scale system
should be installed and operated at the site to verify the treatment
potential of the process and to develop design criteria for a full-scale
system.
