Dear Mr. Goodrich:
This letter is to confirm our discussion on July 12, 2000 regarding sampling of monitoring
well MW-9 as required in Section IV.1 of the subject permit. As we discussed, MW-9 is a
proposed well to be installed during the off -site investigation. This phase of the
investigation has not been performed yet pending access agreements from the property
owners. Per your suggestion, sampling of proposed well MW-9 is to be added to the
sampling program after it is installed. Sampling of the remaining monitoring wells (MVV-1
through MW-6) will continue according to the permit.
I also would like to confirm my understanding from Ms. Teresa Rodriguez that in regards
to the system classification as described in Section 11.2, the subject system has not been
classified as of June 26, 2000, and that R. P. Scherer will be notified when such
classification takes place. In the meantime, please be aware that the system is being
inspected daily by a Class II Wastewater ORC pending system classification.

EPA Method 6210D plus Acetone
3. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.
4. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in 15A
NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary for the
disposal system constructed prior to December 31, 1983 is established at either (1) 250 feet from
the waste disposal area, or (2) 50 feet within the property boundary, whichever is closest to the
waste disposal area. An exceedance of Groundwater Quality Standards at or beyond the
Compliance Boundary is subject to immediate remediation action in addition to the penalty
provisions applicable under General Statute 143-215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the disposal
systems midway between the Compliance Boundary and the perimeter of the waste disposal area.
Any exceedance of standards at the Review Boundary shall require remediation action on the part
of the permittee.
4. All wells that are constructed for purposes of groundwater monitoring shall be constructed in
accordance with 15A NCAC 2C .0108 (Standards of Construction for Wells Other than Water
Supply) and any other state and local laws and regulations pertaining to well construction.
The Mooresville Regional Office, telephone number [phone], shall be notified at least
forty-eight (48) hours prior to the construction of any monitoring well so that an inspection can be
made of the monitoring well location. Such notification to the regional groundwater supervisor
shall be made during the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through
Friday, excluding state holidays.
Within sixty (60) days of completion of all monitoring wells, the permittee shall submit two
original copies of a scaled topographic map (scale no greater than 1":100) signed and sealed by a
professional engineer or a state licensed land surveyor that indicates all of the following
information:
a. the location and identity of each monitoring well,
b. the location of the waste disposal system,
c. the location of all property boundaries,
d. the latitude and longitude of the established horizontal control monument,
e. the relative elevation of the top of the well casing (which shall be known as the "measuring
point"), and
f. the depth of water below the measuring point at the time the measuring point is established.
The survey shall be conducted using approved practices outlined in North Carolina General
Statutes Chapter 89C and the North Carolina Administrative Code Title 21, Chapter 56. The
surveyor shall establish a horizontal control monument on the property of the waste disposal

PV
system and determine the latitude and longitude of this horizontal control monument to a
horizontal positional accuracy of +/- 10 feet. All other features listed in a. through e. above shall
be surveyed relative to this horizontal control monument. The positional accuracy of features
listed in a. through e. above shall have a ratio of precision not to exceed an error of closure of 1
foot per 10,000 feet of perimeter of the survey. Any features located by the radial method will be
located from a minimum of two points. Horizontal control monument shall be installed in such a
manner and made of such materials that the monument will not be destroyed due to activities that
may take place on the property. The map shall also be surveyed using the North American Datum
of 1983 coordinate system and shall indicate the datum on the map. All bearings or azimuths shall
be based on either the true or NAD 83 grid meridian. If a Global Positioning System (GPS) is
used to determine the latitude and longitude of the horizontal control monument, a GPS receiver
that has the capability to perform differential GPS shall be used and all data collected by the GPS
receiver will be differentially corrected.
The maps and any supporting documentation shall be sent to the Groundwater Section, N.C.
Division of Water Quality P.O. Box 29578 Raleigh, N.C. 27626-0578.
7. Upon completion of all well construction activities, a certification must be received from a
professional engineer certifying that the monitoring wells are located and constructed in

The Groundwater Section is in receipt of the renewal application for the subject facility,
currently permitted under Permit Number WQ0010607, issued on November 3, 1995. The
existing permit allows the operation of the existing 17,280 GPD groundwater remediation facility
in the City of Monroe (see Figures 1 and 2). The remediation system includes four groundwater
recovery wells, an air stripping unit, and an infiltration gallery.
Monitoring requirements in the existing permit include sampling of the influent and
effluent for EPA Method 6210D plus Acetone, and groundwater monitoring at existing Monitor
Wells MW-1, MW-2, MW-3, MW-4, MW-5, and MW-6 every April, August, and December
for Water Level and EPA Method 6210D plus Acetone. It is the understanding of the
Groundwater Section that two additional wells, MW-7 and MW-8, have since been added
(voluntarily) to the monitoring program. As part of the permit renewal review process, the
Groundwater Section examines historical monitoring data for indications of trends and chronic
exceedance conditions. An examination of the monitoring data for this facility revealed nominal
concentrations of several of the EPA Method 6210D parameters and no detectable concentrations
of Acetone. In view of these data, the Groundwater Section recommends that the sampling
frequency be decreased from three times a year to only two times a year (April and October);
and that no further changes be made in the stated groundwater monitoring requirements of the
existing permit.
The Groundwater Section has reviewed the subject permit renewal application and recommends
reissuance of the permit with the following conditions:

VFV
*1. Existing Monitor wells MW-1, MW-2, MW-3, MW-4, MW-5, and MW-6 shall be sampled
every April and October for the following parameters:
Water Level
EPA Method 6210D plus Acetone
The measurement of water levels must be made prior to sampling for the remaining
parameters. The depth to water in each well shall be measured from the surveyed point on
the top of the casing.
The results of the sampling and analysis must be received on Form GW-59
(Groundwater Quality Monitoring: Compliance Report Form) by the Groundwater
Section, Permits and Compliance Unit, 1636 Mail Service Center, Raleigh, N.C. 27699-
1636 on or before the last working day of the month following the sampling month.
*2. The influent and effluent from the treatment system shall be sampled monthly for the
following parameters:
EPA Method 6210D plus Acetone
3. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
4. The groundwater recovery, treatment and disposal system shall be inspected weekly. If it is
determined that the system is malfunctioning, all repairs should be made as soon as possible
and reported to the Mooresville Regional Office within 48 hours.
5. The groundwater treatment system shall consistently achieve at least a 95 % treatment
efficiency (i.e. remove 95% of the influent contaminants) prior to discharge to the injection
wells. If the treatment system fails to consistently achieve this standard, additional treatment
units or changes in operational methods, may be required.
*This language differs from that of the shell document.

VFV
*6. A water level contour map must also be developed on a yearly basis. Two copies of these
maps shall be submitted along with all other monitoring data for that period.
7. The permittee shall retain copies of records of all monitoring information, including all
calibration and maintenance records, all original strip chart recordings for continuous
monitoring instrumentation and copies of all reports required by this permit, for a period of
at least 3 years from the date of the
sample, measurement, report or application. Records of this monitoring information shall
include, but not be limited to, the following:
a. the date, exact place, and time of sampling or measurements,
b. the individual who performed the sampling or measurements,
c. the date the analyses were performed,
d. the analytical techniques or methods used, and
e. the results of any such sampling, measurements, and analyses.
8. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in 15A
NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary is for the
disposal system individually permitted after December 31, 1983 is established at either (1) 250
feet from the waste disposal area, or (2) 50 feet within the property boundary, whichever is
closest to the waste disposal area. An exceedance of Groundwater Quality Standards at or
beyond the Compliance Boundary is subject to immediate remediation action in addition to the
penalty provisions applicable under General Statute 143-215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the
disposal systems midway between the Compliance Boundary and the perimeter of the waste
disposal area. Any exceedance of standards at the Review Boundary shall require remediation
action on the part of the permittee.
If there are any questions please let me know.

RE: Modification Request
NPDES Permit No.NC0084344
R.P. Scherer/Chelsea Labs
Union County, N.C.
This letter is a follow-up to our telephone conversation of last week regarding the need to
continue semi -volatile sampling of the influent and effluent for the groundwater remediation
system at the referenced site. According to the groundwater incident file, diesel fuel free product
was discovered in MW-4 in the April of 1997. Monitoring for EPA method 625 compounds was
instituted in April 1998 when the modified remediation system was restarted. No semi -volatile
compounds have been detected since June 1998.
Based on a review of the quarterly monitoring reports, this office has no objection at this
time to deleting the sampling in question from the permit. Naturally, should the presence of
diesel fuel be suspected at a future point in time, monitoring for 625 constituents would need to
be resumed.
If you have any questions, please feel free to call me at 704/663-1699, ext. 238.

This letter is to confirm our telephone conversation of December 9, 1996 in reference to
construction issues for the Interim Groundwater Remediation System at the Chelsea Laboratories
facility in Monroe. The system consists of four extraction wells pumping to a tray type air stripper.
Treated groundwater then flows through a gravity settling tank, and then is pumped to one of two
discharge options. Treated groundwater is first pumped to an infiltration gallery located
upgradient of the extraction well network. The infiltration gallery is intended to push contaminated
groundwater toward the extraction wells. If the infiltration gallery is not able to accept additional
water, then the treated groundwater will be discharged to an NPDES permitted surface discharge.
Construction of the Interim Remediation System began December 2, 1996. Based on the
contractor's schedule, the air stripper buildina, extraction wells, gravity settling tank, and treated
groundwater pump station will be constructed first. The infiltration gallery will be the last
component to be constructed. The infiltration gallery will consist of a 18 to 20 foot deep trench,
approximately 6 feet wide. During the excavation of the trench, surface waters (rainfall runoff),
and perched groundwater may accumulate in the trench. Since this water may come into contact
with contaminated water or soil, the contractor will not be allowed to dewater the trench by
pumping the water to a surface ditch. Since the treatment system, less the infiltration gallery, will
be completed at this point, it is proposed to pump the accumulated water in the trench to the air
stripper for treatment and then discharge the treated water via the NPDES permitted discharge.
Based on our telephone conversation, this approach is acceptable as long as the treated
water is in compliance with the effluent limitations stipulated in the NPDES permit. The
Mooresville Office will be notified at least 24 hours prior to placing the treatment system into
operation. This is also consistent with information given to me by Mr. Randy Kepler in the
Raleigh office. Mr. Kepler reviewed and coordinated the two permits for this project.

Mr. Rex Gleason

Based on the preliminary construction schedule, excavation for the infiltration gallery will
begin in March. We will advise you of any changes to the construction schedule throughout this
project. If you require further information, or have any questions or comments, feel free to call

On January 2, 1996 Rogers & Callcott received NPDES Permit No. NCO084344
dated December 22, 1995. The permit was issued to R. P. Scherer Corporation for
discharge of treated groundwater in excess of the capacity of a proposed infiltration
gallery at the Chelsea Laboratories Facility in Union County.
A draft version of this permit dated August 24, 1995 was issued for public notice.
Rogers & Callcott commented on the draft permit during the public notice period in a
letter dated September 27, 1995. In our response to the draft permit, a request was
made to remove the monitoring requirement for arsenic, lead and mercury and to change
the lower pH limit from 6.0 to 5.5 standard units (S.U.). The request was made based
on the data available at that time, which indicated that the three metals and pH levels in
the groundwater at the site are typical of groundwater natural conditions in this area of
the Piedmont. The final NPDES permit was issued with an agreement to re-evaluate the
metals limits after 12 months of data are collected, but without modifications to the metals
and pH limits.

In response to the final permit, groundwater samples were collected from on -site
monitoring wells for laboratory analysis to confirm the background quality of groundwater
at the site and provide a comparison with the proposed recovery wells. Mr. Randy
Kepler, DEM's permit engineer, was informed of the additional data collection in a
telephone conversation on January 24, 1996. Mr. Kepler indicated that the Division is
willing to review the new data once they become available and reconsider the effluent
limits proposed by the permit. Mr. Kepler also indicated that the Division will review the
new data outside an adjudicative hearing. He advised, however, that the hearing process
be maintained as an option. Subsequently, a petition for an adjudicative hearing was filed
with the Office of Administrative Hearings with a copy submitted to your office on January
26, 1996.
Field Sampling
Groundwater samples were collected from on -site monitoring wells MW-1 through
MW-7 on January 22 and 23, 1996. Wells MW-1, MW-6 and MW-7 are located
hydraulically up -gradient from the area impacted by the volatile organic compounds
(VOC's). Wells MW-2, MW-3, MW-4 and MW-5 are proposed recovery wells located
within the impacted area.
The seven wells were sampled and analyzed for arsenic, lead, mercury and pH.
The samples were also analyzed for iron and (VOC's) to obtain current data before
beginning construction of the remediation system. The metals analyses were performed
by two methods to determine the acid -extractable concentrations (Standard Method
3030C) and the total concentrations. For field quality control purposes, a blind duplicate
sample was collected from MW-2 for metals analysis. A second blind duplicate sample
was collected from MW-3 for VOC's analysis. Other field quality control samples included
a trip blank and an equipment balnk for VOC's analysis.
The pH measurements, along with conductivity and temperature, were obtained
using calibrated instruments in the field during well purging. Several readings were
obtained from each well with one reading obtained before purging began and one reading
after each well volume was removed.
Sample handling procedures were performed in accordance with EPA's
Environmental Compliance Branch Standard Operating Procedures and Quality
Assurance Manual. Analytical methods are listed in the Analysis Chronology section of
the attached laboratory report.

Analytical Results and Recommendations
The attached Tables I and II are summaries of the metals and pH analytical
results, respectively, available to date from the site. Complete laboratory analysis, quality
control and field sampling reports are also attached. The following is a discussion of the
results:
Arsenic
Total arsenic was detected in background samples MW-1 and MW-7 at 0.0095 and
0.0055 mg/I, respectively. Total arsenic was also detected in proposed recovery wells
MW-2 and MW-5 at 0.0081 and 0.014 mg/I, respectively. No arsenic was detected in
background well MW-6 and proposed recovery wells MW-3 and MW-4 at a detection limit
0.005 mg/I. The arsenic effluent limit proposed in the NPDES permit is 0.05 mg/I (Table
1).
Lead
Total lead was detected in background samples MW-1, MW-6 and MW-7 at 0.018,
0.0056 and 0.014 mg/I, respectively. Total lead was also detected in proposed recovery
wells MW-4 and MW-5 at 0.005 and 0.028 mg/I, respectively. No lead was detected in
proposed recovery wells MW-2 and MW-3 at a detection limit of 0.005 mg/I. The lead
effluent limit proposed in the NPDES permit is 0.025 mg/I (Table 1).
Mercury
Total mercury was detected in background samples MW-1 and MW-6 at 0.0004
and 0.0012 mg/I, respectively. Total mercury was also detected in proposed recovery
well MW-5 at 0.0005 mg/I. No mercury was detected in background well MW-7 and
proposed recovery wells MW-2, MW-3 and MW-4 at a detection limit 0.0002 mg/l. The
mercury effluent limit proposed in the NPDES permit is 0.000012 mg/I, which is below the
lowest achievable detection limit using EPA's and NCDEHNR's approved analytical
methods (Table 1).
pH
The average pH measurements of several readings collected from background
wells MW-1, MW-6 and MW-7 since 1993 range between 5.4 and 6.8 S.U. with an
average of 6.0 S.U. The average pH measurement from the three background wells
during the latest sampling event in January 1996 is 5.8 S.U. The average pH
measurements of several readings collected from the proposed recovery wells MW-2,
MW-3, MW-4 and MW-5 since 1993 range between 5.2 and 6.8 S.U. with an average of
6.2 S.U. The average pH measurement from the four proposed recovery wells during the
latest sampling event in January 1996 is 5.7 S.U. (Table II).

Conclusions
Based on the latest laboratory data obtained from seven of the on -site wells, it is
evident that the metal concentrations and pH values in the proposed recovery wells are
also present at levels comparable with those in the background wells. Additionally, there
is no known metal contamination at the site. Therefore, the following observations and
recommendations are presented for your consideration:
Arsenic
1- The arsenic concentration detected in MW-2 in October 1993 at 0.012 mg/I
has decreased to 0.0081 mg/I during the latest sampling event in January
1996. This result was confirmed by the analysis of the blind duplicate
sample from MW-2 in which arsenic was detected at 0.0093 mg/I.
2- Arsenic was detected in two of the background wells and two of the
proposed recovery wells.
3- The detected arsenic concentrations are less than the proposed effluent
limit.
Recommendation:
There is no reasonable justification to warrant monitoring for arsenic. This
requirement should be totally removed from the permit.
Lead
1- The lead concentration detected in MW-2 in October 1993 at 0.068 mg/I
was not detected during the January 1996 sampling event at a detection
limit of 0.005mg/I. This result was confirmed by the analysis of the blind
duplicate sample from MW-2 in which no lead concentration was detected.
2- Lead was detected in all three of the background wells and only one of the
proposed recovery wells (MW-5).
Recommendation:
Rogers & Callcott agrees with the Division's position to re-evaluate the
permit requirements after collecting one year of data. However, the daily
maximum lead concentration should be replaced with a monitor and report
requirement due to the presence of lead at comparable levels in the
background samples.

Mr. David A. Goodrich
February 8, 1996
Page 5 of 6
Mercury
1- The mercury concentration reported in MW-2 in October 1993 at 0.0002
mg/I was not detected during the January 1996 sampling event at detection
limit of 0.0002 mg/I. This result was confirmed by the analysis of the blind
duplicate sample from MW-2 in which no mercury was detected.
2- Mercury was detected in two of the background wells and only one of the
proposed recovery wells.
3- The proposed mercury effluent limit was based on the acid -extractable
mercury concentration reported in MW-2 in October 1993, which is an
artifact of the analytical method and an unreliable value as indicated by the
analysis report (attached) for the following reasons:
a- The reported mercury concentration was equal to the method
detection limit of 0.0002 mg/I.
b- An acid -extractable mercury concentration at the same level of
0.0002 mg/1 was reported in the bailer rinsate sample during the
same sampling event.
c- The presence of mercury was not confirmed by the total mercury
analysis in the same field and quality control samples and at the
same detection limit.
4- The proposed effluent limit for mercury at 0.000012 mg/I is significantly
lower than the laboratory detection limit of 0.0002 mg/I achievable by the
latest approved analytical method.
Recommendation
There is no reasonable justification to warrant monitoring for mercury. As
demonstrated in this case, a reported value at or near the sensitivity level
of the analytical instrument would unjustifiably place the permittee in
violation of the permit limit. Therefore, this requirement should be totally
removed from the permit.
pH
1- It is evident that the pH of the groundwater at the site has not been affected
by the contaminants. The groundwater pH in the background wells is
similar to that of the proposed recovery wells.

I
Mr. David A. Goodrich
February 8, 1996
Page 6 of 6
2- The pH of groundwater at the site including background conditions is very
close to and sometimes lower than the minimum pH limit of 6.0 S.U.
proposed in the permit.
Recommendation
Meeting the proposed lower pH limit of 6.0 S.U. may not be possible
without altering the natural pH of the groundwater at the site. Therefore,
based on the existing and recently acquired data, and as previously
requested in our response to the draft NPDES permit, it is recommended
that the proposed minimum pH limit be lowered to 5.5 S.U.
We wish to commence construction of the remediation system as soon as possible.
However, the effluent standards proposed in the permit cannot be accepted knowing that
the permittee may be in violation of the permit conditions and would be subject to fines
due to naturally occurring conditions. We do not believe that it is the intent of the NPDES
permitting process to alter the natural conditions of groundwater prior to discharging it into
a stream.
We would like the opportunity to discuss these matters with you prior to reaching
a final decision. I will contact you shortly to set up a teleconference or a face-to-face
meeting. If you have any questions in the meantime, please contact me at (864)232-
1556. Thank you for your cooperation on this project.

The Groundwater Section received a phone conversation and a written request (copy
attached) on September 29, 1995 to modify the issued permit. The request fell under the 30 days
since issuance, so we have proceeded as if it were an adjudication. The letter indicates three
areas of concern.
The first concerns the groundwater testing method. The consultant would like to be able
to conduct the testing themselves. They are certified to use Method 8260, however, the detection
limits for this method are not low enough to evaluate 2L standards. After a conversation with the
consultants, I have proposed using method 621 OD, which has the proper detection range and they
can get certified in. This was agreed to by David Scott of Rogers & Callcott Engineers, and I
agreed the permit should be changed to this method.
The second issue was the proposed new well MW-9. The placement we proposed is not
possible due to power lines, excessive slope, and a busy road which would have to be blocked
during construction. The only feasible area is close to existing monitoring wells. We have
decided to drop this requirement.
The third issue was the Review/Compliance Boundary language. I have informed the
consultant that the remediation and penalty language does not pertain to the existing condition,
only to actions conducted under the permit.
We recommend that the permit be amended to as follows:
Condition IV.1. should be deleted from the permit.

Condition IV.2.-MW-9 should be removed.
Condition IV.2-EPA Method 501.2 and 502.2 should be changed to Method 6210D plus
Acetone.
Condition IV.3.-EPA Method 501.2 and 502.2 should be changed to Method 621 OD plus
Acetone.
Condition IV.5, 6, 8, and 9 should be deleted from the permit.
If you have any questions please call me at 715-6163.

MOORESVILLE REGIONAL OFFICL
The Groundwater Section has reviewed the subject permit application. The system
is designed to pump 12 gpm from four recovery wells, treat the water through a air stripper,
and dispose of through an infiltration gallery and NPDES discharge. When the water level
in an observation well next to the gallery reaches a set point (not less then one foot below
the gallery), flow to the gallery is halted and discharge starts. According to the
consultants, the gallery should accept 225 gpd. This leaves 17,055 gallons per day surface
water discharge. However, due to the fractured rock the gallery will be set on, this number
may vary.
An additional monitoring well should be installed south of the recovery wells. The
wells should be constructed deeper then the recovery wells to verify that the system is not
pushing contamination deeper into the bedrock aquifer. We recommend issuance of the
permit with the following conditions:
* 1. Prior to beginning waste disposal operations, one (1) monitor well shall be
installed to monitor groundwater quality. The well shall be constructed to a
depth 10 feet greater then any recovery well (MW-2, MW-3, MW-4, or MW-
5). The general location and name for each well is marked on Attachment A.
Each monitoring well shall be constructed in accordance with this permit, and
approved by the Mooreseville Regional Office.

PV
2. Monitor wells MW-I, MW-2, MW-3, MW-4, MW-5, MW-6, and MW-9
shall be sampled initially after construction and thereafter every April,
August, and December for the following parameters:
Water Level
EPA Methods 501.2 and 502.2
3. The measurement of water levels must be made prior to sampling for the
remaining parameters. The depth to water in each well shall be measured
from the surveyed point on the top of the casing.
4. The measuring points (top of well casing) of all monitoring wells shall be
surveyed to provide the relative elevation of the measuring point for each
monitoring well.
The results of the sampling and analysis shall be sent to the Groundwater
Section, Permits and Compliance Unit, P.O. Box 29535 Raleigh, N.C. 27626-
0535 on Form GW-59 [Compliance Monitoring Report Form] every May,
September, and January.
6. The influent and effluent from the treatment system shall be sampled once
every two (2) weeks for the first three (3) months and monthly thereafter for
the parameters specified below:
EPA Methods 501.2 and 502.2
The results of the sampling and analysis shall be sent to the Groundwater
Section, Permits and Compliance Unit, P.O. Box 29535 Raleigh, N.C. 27626-
0535 within 30 days of sample collection.
7. Any additional groundwater quality monitoring, as deemed necessary by the
Division, shall be provided.
8. All wells that are constructed for purposes of groundwater monitoring shall be
constructed in accordance with 15A NCAC 2C .0108 (Standards of
Construction for Wells Other than Water Supply) and any other state and
local laws and regulations pertaining to well construction.
9. The Mooresville Regional Office, telephone number [phone], shall be
notified at least forty-eight (48) hours prior to the construction of any
monitoring well so that an inspection can be made of the monitoring well
location. Such notification to the regional groundwater supervisor shall be

PV
made during the normal office hours from 8:00 a.m. until 5:00 p.m. on
Monday through Friday, excluding state holidays.
10. Within sixty (60) days of completion of all monitoring wells, the permittee
shall submit two original copies of a scaled map (scale no greater than
1 ":100') signed and sealed by a state licensed land surveyor that indicates all
of the following information:
a. the location and identity of each monitoring well,
b. the location of all components of the waste disposal system,
c. the location of all property boundaries,
d. the latitude and longitude of the established horizontal control
monument,
e. the relative elevation of the top of the well casing (which shall be
known as the "measuring point"), and
f. the depth of water below the measuring point at the time the
measuring point is established.
This survey shall be conducted using approved practices outlined in North
Carolina General Statutes Chapter 89C and the North Carolina Administrative
Code Title 21, Chapter 56. The surveyor shall establish a horizontal control
monument on the property of the waste disposal system and determine the
latitude and longitude of this horizontal control monument to a horizontal
positional accuracy of +/-10 feet. All other features listed in a. through e.
above shall be surveyed relative to this horizontal control monument. The
positional accuracy of features listed in a. through e. above shall have a ratio
of precision not to exceed an error of closure of 1 foot per 10,000 feet of
perimeter of the survey. Any features located by the radial method will be
located from a minimum of two points. Horizontal control monuments shall
be installed in such a manner and made of such materials that the monument
will not be destroyed due to activities that may take place on the property.
The map shall also be surveyed using the North American Datum of 1983
coordinate system and shall indicate the datum on the map. All bearings or
azimuths shall be based on either the true or NAD 83 grid meridian. If a
Global Positioning System (GPS) is used to determine the latitude and
longitude of the horizontal control monument, a GPS receiver that has the
capability to perform differential GPS shall be used and all data collected by
the GPS receiver will be differentially corrected.
The maps and any supporting documentation shall be sent to the Groundwater
Section, N.C. Division of Environmental Management P.O. Box 29535
Raleigh, N.C. 27626-0535.

Or
11. Upon completion of all well construction activities, a certification must be
received from a professional engineer certifying that the monitoring wells are
located and constructed in accordance with the Well Construction Standards
(15A NCAC 2C) and this permit. This certification should be submitted with
copies of the Well Completion Form (GW-1) for each well. Mail this
certification and the associated GW-1 forms to the Permits and Compliance
Unit, Groundwater Section, P.O. Box 29535, Raleigh, NC, 27626-0535.
12. For the initial sampling of the well as specified elsewhere in the permit, the
permittee shall submit a copy of the GW-1 Form (Well Completion Form)
with the Compliance Monitoring Form (GW-59) for that well. Compliance
Monitoring Forms that do not include copies of the GW-1 form will be
returned to the permittee without being processed. Failure to submit these
forms as required by this permit may result in the initiation of enforcement
activities pursuant to NC General Statutes 143-215.6.
13. All components of the groundwater recovery, treatment, and disposal system
shall be properly weather -proofed to prevent freezing and failure of the
system.
14. The groundwater recovery, treatment and disposal system shall be inspected
weekly. If it is determined that the system is malfunctioning, all repairs
should be made as soon as possible and reported to the Mooresville Regional
Office within 48 hours.
* 15. The groundwater treatment system shall consistently achieve at least a 95%
treatment efficiency (i.e. remove 95% of the influent contaminants) prior to
discharge to the infiltration gallery. If the treatment system fails to
consistently achieve this standard, additional treatment units or changes in
operational methods, may be required.
* 16. A water level contour map must also be developed on a yearly basis. These
maps shall be submitted along with all other monitoring data for that period.
17. The permittee shall retain copies of records of all monitoring information,
including all calibration and maintenance records, all original strip chart
recordings for continuous monitoring instrumentation and copies of all
reports required by this permit, for a period of at least 3 years from the date of
the sample, measurement, report or application. Records of this monitoring
information shall include, but not be limited to, the following:
a. the date, exact place, and time of sampling or measurements,
b. the individual who performed the sampling or measurements,

Pr
C. the date the analyses were performed,
d. the analytical techniques or methods used, and
e. the results of any such sampling, measurements, and analyses.
18. The COMPLIANCE BOUNDARY for the disposal system is specified by
regulations in 15A NCAC 2L, Groundwater Classifications and Standards.
The Compliance Boundary for disposal systems constructed after December
31, 1983 is established at either (1) 250 feet from the waste disposal area, or
(2) 50 feet within the property boundary, whichever is closest to the waste
disposal area. An exceedance of Groundwater Quality Standards at or beyond
the Compliance Boundary is subject to immediate remediation action in
addition to the penalty provisions applicable under General Statute 143-
215.6A(a)(1).
19. In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established
around the disposal systems midway between the Compliance Boundary and
the perimeter of the waste disposal area. Any exceedance of standards at the
Review Boundary shall require remediation action on the part of the
permittee.

SUBJECT: R.P Scherer/Chelsea Labs

WQ0010607/GW95052
The following are my thoughts on the subject site. I'm typing this memo so you won't
have to decipher my chicken scratch.
The remedial design has been revised since my additional information letter and meeting
with the consultants. This new design has eliminated the injection well. The difficulty with
modeling the bedrock aquifer to show closed -loop, as required under G.S.143-215.IA, forced the
removal of the well.
An NPDES application has also been submitted to WQ. The plan is that when the gallery
fills to a preset level, the system will discharge the extra effluent to a storm water ditch. This
should eliminate the need for a soil scientist report on the loading rate for the gallery.
The air stripper looks good. The Technical Specifications manual indicates that the
effluent will meet or exceed 2L standards for all constituents except tetrachloroethene. However,
it is cleaned better then 95% and the gallery is upgradient of the recovery wells, so it shouldn't be
a hangup.
I agree with your previous comment for the addition of one monitoring well North of the
recovery wells. However, I believe this area is not owned by the applicant. My difficulty is
wording the permit to dictate the well and then the property owner not allow the well. This
would be an automatic permit violation. Any suggestions you have on wording would help. I
may call the consultant and see if they have approached the owner before.
If you have any questions please call me at [phone] ext. 406. Thanks for your
help.

Groundwater Remediation
System
Union County
The Division of Environmental Management's Permits and Engineering Unit and Groundwater
Section have completed a preliminary engineering review of the subject application.
The following items must be addressed before we can complete our review:
Information requested by the Groundwater Section
1) Because the injection well is outside the contaminate plume, the injected water will have
to meet 15A NCAC 2L Groundwater standards prior to injection. Therefore, please
demonstrate, submit calculations, etc. that the treatment system can remove the
contaminates to this level.
2) The injection well must act in a closed -loop manner, according to G.S. 143-215. LA. A
demonstration must be presented that the system will act in a closed -loop manner, i.e.
injected water must be recaptured by the recovery wells.
3) Groundwater Section guidelines specify that the infiltration Gallery's "design flow must
not result in saturated conditions within one vertical foot of the excavated bottom of the
gallery". The system cross-section, provided in the application, indicates that the water
table will mound over the infiltration gallery. The system should be designed to prevent
this situation. Please submit information showing the guidelines will be met.
Information requested by the Permits and Engineering Unit
1) Please provide details of the treatment system, i.e. well pumps and curves, sizes of the
settling chamber and finished water chamber, etc.
P.O. Box 29535, Raleigh, North Carolina 27626-0535 Telephone [phone] FAX [phone]
An Equal Opportunity Affirmative Action Employer 50% recycled/ 10% post -consumer paper

2) The piping schematic shows a possible discharge to the surface waters of the state in
certain circumstances where the infiltration gallery or injection well cannot handle the
flow. This permit application is for a non -discharge permit for groundwater remediation.
This means that under any circumstances no discharge may occur and the facility cannot
have a bypass to the surface waters as an emergency option. This schematic must be
revised to eliminate any possibility for discharge. If a discharge is possible, the system
should be redesigned to prevent any discharge.
3) Please provide a soil scientist's report of the soils or fractured bedrock to establish an
acceptable loading rate. (see application letter g on page 6 of 9). Also Part V.3 and 4 of
the application (page 3 of 9) needs to be completed based on the soil scientist's report.
4) Please complete Part V D and 4 of the application (page 5 of 9) concerning the buffer
requirements being met and if any substances are added to enhance treatment.
5) Please provide calculations showing how must treated groundwater is being intended for
both the injection well and the infiltration galleries. What percentage of the flow will go
to each?
6) Please provide one additional copy of the corrective action plan and site assessment
Refer to the subject permit application number when providing the requested information. Prior
to submittal of the additional information, please review pages 5 and 6 of 9 of the application to insure all
the needed information is being or has been submitted. Please submit four copies of all
requested information to my attention at the address below except for P&E number 6.
Also, please note that failure to provide this additional information on or before May 6, 1995 will subject
your application to being returned as incomplete, in accordance with 15A NCAC 2H .0208.
If you have any questions regarding the information requested by the Groundwater Section,
please call Brian Wagner at 91gn33-5083 ext. 406. If your questions concern the information requested
by the Permits and Engineering Unit, please call me at 919/ 733-5083 ext. 544.

Subject: Non -Discharge Permit Application
R.P. Scherer/Chelsea Laboratories Facility
2021 East Roosevelt Boulevard
Monroe, Union County, North Carolina
Dear Ms. McCaskill:
Enclosed is a Non -Discharge Permit Application with conceptual
design drawings and a $400 application fee for the subject
facility. Also enclosed are two copies of the Phase I Remedial
Investigation Work Plan and Report.
Remediation System Concept
The purpose of the Interim Remediation System is to address
on -site groundwater contamination identified to date and minimize
the potential for off -site contaminant migration. Upon completion
of the Remedial Investigation, the recovery system may be expanded
to expedite the remediation effort.
The proposed Interim Remediation System will consist of
converting four monitoring wells into pumping or recovery wells;
installing an air stripping unit to treat contaminated groundwater;
constructing an infiltration gallery to introduce treated
groundwater upgradient of the recovery wells and area of
contamination; converting an existing monitoring well to a shallow
injection well upgradient of the infiltration gallery and
upgradient of the contaminant plume; and maintaining a background
monitoring well upgradient of the shallow injection well.
The figure found on the following page is a schematic of the
hydraulic concept of the system. When in operation, treated water
in the infiltration gallery and injection well will raise the water
table in that area while the recovery wells will create a
depression in the water table. The resulting hydraulic profile
should further influence groundwater flow toward the recovery
wells. Therefore, the purpose of the infiltration gallery and the
shallow injection well is to expedite the remediation effort.

Since the infiltration gallery and the shallow injection well
are located on or in the bedrock formation, an accurate estimate of
the respective feed rates is not available. It is the intent to
pump as much treated water to the infiltration gallery and
injection well with the excess amount going to a permitted outfall.
This will allow the entire remediation system to operate in an
optimal manner and expedite the remediation effort.
The system design concept and details are presented in
Appendix J of the Phase I Remedial Investigation Report.
NPDES Permit Application
An NPDES Permit Application was submitted to the NCDEHNR on
June 16, 1994. The review has been put on hold pending the outcome
of this application. Based on telephone conversations with Mr.
Sean Goris in the Water Quality Section, the NPDES section would
resume the review of the NPDES Application if the Non -Discharge
option is not permitted or fails to perform adequately.
Final Plans and Specifications
Final Construction Plans and Specifications will be prepared
and submitted upon review and approval of this application. The
final design will include contingencies to accommodate an NPDES
discharge point that will be constructed if and when.a discharge is
deemed necessary.
Non -Discharge Permit Submittal
The following comments are in reference to the items found on
pages 5 and 6 of the Non -Discharge Permit Application (Form GWRS
06/94).
Item c. Based on conversations with Mr. Jack Floyd of NCDEM's
Groundwater Section and George Maalouf of Rogers &
Callcott, the information contained in the enclosed NPDES
Application package will serve as the Corrective Action
Plan. This document may be found in Appendix J of the
Phase I Remedial Investigation Report. Also, the Phase
I Remedial Investigation Work Plan and Report will serve
as the Comprehensive Site Assessment. The Phase I
Remedial Investigation Work Plan has previously been
submitted to Mr. John Walch of the Inactive Hazardous
Sites Branch, Superfund Section. A copy of the Work Plan
is enclosed.
Item d. N/A. This is not a permit renewal.

it was determined that a soil scientist evaluation would
not be beneficial.
Item h. A hydrogeologic description of the site can be found in
Section 1 of the RI Report.
Item I. A description of the remediation system including the
injection process can be found in Section III of the
NPDES Permit Application.
Item j. The proposed monitoring schedule may be found in Section

system fail, there will be a return line to the treated
water sump for returing any overflow. Inspection of the
injection well will be part of routine maintenance.
Refer to the Conceptual Design Drawings.
Item 1. An analysis of the contaminated groundwater can be found
in Section 4.0 of the RI Report (Table 3).
Item M. Treatment will be provided with a low profile, tray type
air stripper. Vendors have been contacted to verify if
the proposed limits can be met. These limits are
addressed in Section III of the NPDES Application.
Item n. Diagrams of the contaminant plume can be found on Figures
11 through 16 in the RI Report.
Item P. A site visit was conducted by Mr. G.T. Shin of the
Mooresville Regional Office, Water Quality Section on
August 2, 1994. The visit was a follow-up to the NPDES
Permit Application. We understand that a report from the
Regional Office was submitted to Mr. Sean Goris in
Raleigh. In reference to the stream classification, the
unnamed tributary located north of the site has been
classified as a Class C stream as part of the NPDES
review and Waste Load Allocation. A copy is attached.

A number of halogens and volatiles were found at the site. Using a removal efficiency of 90% for
these constituents, tetrachloroethene, triehloroethene, and toluene should be limited to water quality
standards or EPA criterion. Chloroform should be monitored. A number of metals were found
above or near the water quality standards and should be limited. These include: arsenic, lead and
mercury. BETX parameters appear at the site, but only toluene was in high enough concentrations
to need a limit. A quarterly, chronic WET test will be given as a pass/fail analysis at 90%. Ph and
Oil and Grease will be limited per current policy. The testing results submitted by the applicant
have raised concerns that other halogens may be present and were not adequately reported in the
data. Because of this.it is recommended that further volatiles and base/neutral - acid extractable
testing be performed on the effluent. It is recommended that volatiles be tested using EPA methods
601 & 602 be done quarterly and that base/neutral - acid extractable testing be performed with 10
significant peaks identified quarterly, with the 02tion given to discontinue testing after 12 months.
Information ,sent by the facility from samples collected in the plume were the basis for these

II. HISTORY OF GROUNDWATER CONTAMINATION RELATED TO THIS PROJECT
Chelsea Laboratories, Inc. of Monroe, North Carolina is a manufacturer of medicine tablets. This facility
was constructed, owned and operated by R. P. Scherer Corporation in 1976 for the manufacturing of soft
gelatin capsules. Chelsea purchased this facility from R. P. Scherer in January 1986 and has operated it
since that time.
During cleanup of a diesel fuel spill in July 1992, Chelsea discovered tetrachloroethene (PCE) soil
contamination in the vicinity of the diesel spill area. Chelsea excavated the soil and notified R. P. Scherer
of the contamination. With approval from the North Carolina Department of Environment, Health, and
Natural Resources (NCDEHNR), R. P. Scherer transported the contaminated soil to an appropriate
disposal/treatment facility and initiated a preliminary soil and groundwater investigation in the area of
the PCE contamination. The investigation indicated the presence of limited PCE contamination in the soil
and elevated PCE contamination in the groundwater at the northeast corner of the building. Summaries
of the groundwater analysis and the maximum concentration of contaminants found are attached. The
volatile analysis was performed using EPA Method 8260. Additionally, semi -volatile analyses using EPA
Method 8270 and metals analyses were performed on well MW-2. No semi-volatiles or metals were
detected with the exception of iron and manganese. Refer to Appendix B for copies of the laboratory
analyses.
Based on the findings of a preliminary investigation, R. P. Scherer and NCDEHNR's Inactive Hazardous
Sites Branch determined the need for a Remedial Investigation to delineate the extent of soil and
groundwater contamination, and design and implement appropriate remedial action. The site was
designated number 51 on the Inactive Hazardous Waste Sites Priority List dated March 11, 1994.

III. PROPOSED TREATMENT FACILITIES - INTERIM GROUNDWATER REMEDIATION
SYSTEM
The purpose of the Interim Remediation System is to address on -site groundwater contamination identified
to date. Upon completion of the Remedial Investigation, the recovery system may be expanded to expedite
the remediation effort.
The proposed Interim Remediation System will consist of converting four monitoring wells into pumping
or recovery wells; installing an air stripping unit to treat contaminated groundwater; constructing an
infiltration gallery to introduce treated groundwater upgradient of the recovery wells and area of
contamination; converting an existing monitoring well to a shallow injection well upgradient of the
infiltration gallery and upgradient of the contaminant plume; and maintaining a background monitoring
well upgradient of the shallow injection well.
The proposed groundwater remediation system is presented schematically in Drawing 1 (P & I Diagram);
a preliminary site plan showing the location of the proposed facilities is presented in Drawing 2 (Site
Plan). The unit processes include:
Four pumping/recovery wells
Air stripping unit
Gravity settling chamber
Finished water pump station
Shallow injection well
Infiltration gallery.
The figure found on the following page is a schematic of the hydraulic concept of the system. When in
operation, treated water in the infiltration gallery and injection well will raise the water table in that area
while the recovery wells will create a depression in the water table. The resulting hydraulic profile should
further influence groundwater flow toward the recovery wells.
Pumping Wells
Monitoring wells MW-2, MW-3, MW-4, and MW-5 will be converted to groundwater recovery wells.
This will require reaming monitoring wells MW-3, MW-4, and MW-5 to 6 inches in diameter and
installing pumps, controls, and piping. Well MW-2 is constructed with a 2-inch diameter stainless steel
casing and will be fitted with a smaller pump.
The well pumps will be controlled by well water elevation with level probes. In addition, float switches
at the finished water sump will control pump operation to prevent overfilling of the sump.
Anticipated well yields observed during well drilling and development are as follows:

Air Stripping
Contaminated groundwater recovered by the pumping wells will be pumped to a low profile, skid -
mounted air stripper. The air stripper will be sized for 50 gpm. This will allow full utilization of the air
stripper and flexibility to accommodate future wells as needed during progression of site remediation. The
air stripper will be housed in a 20 foot by 30 foot metal building. This building can also serve as the
operator's office, record keeping and general storage area for the remediation project. As a convenience,
flow meters for the pumping wells and some pump controls may be installed inside the building.
The air stripper will include a blower, prewired controls, control panel, and gravity discharge. The PCE
concentrations should be reduced to less than 0.002 mg/l. The preliminary design criteria for the air
stripper is presented below:

The attached table shows the weighted average of the air stripper influent.
Gravity Settling
Naturally occurring iron in the groundwater may be oxidized by the air stripper and precipitate. A settling
tank will be provided downstream of the air stripping unit to allow for settling of the oxidized iron and
other sand or sediment that may be in the recovery water. The tank will have an approximate volume of
1,400 gallons. This will provide a detention time of 28 minutes at 50 gpm or almost 2 hours at 12 gpm.
It is proposed to provide a precast concrete or a poured in place concrete tank with a high density
polyethylene (HDPE) liner.
Finished Water Pumping
Treated water from the air stripper and gravity settler will flow to a pumping station. The pump station
will be supplied with duplex submersible pumps. The pump station will pump treated groundwater to
the shallow injection well and infiltration gallery. During times when the submersible pump yield
exceeds the ability of the shallow injection well and infiltration gallery to accept the total flow from the
treatment unit, treated water can be recirculated to the air stripper.
This system may produce and treat more water than can be returned via the shallow injection well and
infiltration gallery. Therefore, a surface discharge is sought. An NPDES permit will allow for optimal
operation of the system. Operation of the recovery wells can continue while allowing time for the treated
water in the infiltration gallery to infiltrate thus expediting the remediation process.
The pump station sump will be either a HDPE or HDPE-lined manhole.

Infiltration Gallery
To enhance the clean up effort, an infiltration gallery is proposed as and integral part of the overall
remediation system. The infiltration gallery will reintroduce treated water to the area of contamination
raising the head in that area. This water should travel the same path through the fractures as the
contaminant. As a result, the additional head and water supply from the infiltration gallery should enhance
the recovery of contaminants by the pumping wells.
The infiltration gallery will consist of two 150-foot long parallel pipes surrounded by stone. The piping
material will be perforated corrugated ABS plastic pipe (commonly referred to as French drain). This pipe
will be installed in a 6-foot wide trench excavated to the bedrock layer (approximate elevation 980 feet
MSL). The pipe will be installed with "full envelope" bedding using 3/4 inch diameter washed stone. This
will allow the treated water to percolate from the pipes and into the surrounding formation. The bedding
will be approximately 2 feet deep. The remainder of the trench will be backfilled with suitable material.
The infiltration gallery will be located as shown on Drawing 2.
Flow to the infiltration gallery and the head on the infiltration gallery will be controlled with a float valve
located in a sump. The float valve would close when the level of water in the infiltration gallery reaches
a predetermined elevation. A solenoid valve and mercury float switch will be provided as a backup to
the float valve. ije `-a

influence the groundwater flow direction toward the recovery wells.
If either the solenoid valve or electrode fails, a well overflow line will return the excess water to the
pump station sump.
System Piping
All piping with the exception of the well head piping, piping inside the equipment building, piping near
the injection well encasement, and well head piping at the infiltration gallery will be HDPE - PE 3408
piping.

SYSTEM PERFORMANCE AND EVALUATION
Scheduled sampling of water from the recovery wells, treated water, and water from the background
wells will begin at the time of system start-up. This data will be used to evaluate the performance of the
system and monitor plume movement. The proposed sampling schedule is presented below:

IV. EVALUATION OF ENVIRONMENTAL FEASIBILITY OF DISCHARGE ALTERNATIVES
Several non -surface water discharge options have been pursued and are discussed below.
A. Connection to Sewerage System.
Numerous contacts with the City of Monroe were initiated at different points of this project. An initial
request was made to the City on January 11, 1994 to accept purge water from several wells on the R.
P. Scherer/Chelsea Laboratories site. This request was followed up by delivering several published
articles from EPA guidance documents on treatability of RCRA compounds. This request was denied (see
letter of January 24, 1994, Frederick to Maalouf, Appendix A).
A request for permission to discharge treated groundwater to the City of Monroe was made May 2, 1994.
Again, the City denied the request by letter (see letter by Mr. Tom Frederick dated May 25, 1994 in
Appendix A) citing the following reasons:
1. The City of Monroe Treatment Plant was not established for the purpose of receiving VOC-
pretreated wastewater nor is designed for this purpose.
2. No additional benefits would be gained by passing the treated water through the municipal
system.
3. The wastewater would result in a low revenue return to the City and may impose significant
risks or costs. The City also does not have the expertise to permit or monitor this type of
discharge.
R. P. Scherer offered to pay the expenses for the City to obtain a consultant to provide expertise in
evaluating the impacts of receiving this water into their system. The City did not accept this offer. As
a result, this alternative is not implementable and therefore not feasible.
B. On -Site Disposal.
Three options were proposed to Chelsea Laboratories, Inc. on behalf of R. P. Scherer. R. P. Scherer
does not own land in the Monroe, NC area. The options include using the treatment discharge as makeup
water for the cooling tower, and using the discharge water as irrigation water. Subsurface disposal of the
effluent was also considered. These options were discussed with Chelsea and with Marion Merrell Dow
Inc., the parent company of Chelsea.
A conference call was initiated on April 22, 1994 with Mr. Al Baker of Marion Merrell Dow Inc. and
Mr. Ben Baker of Dow Corporation to discuss the preliminary design concept. This was followed with
a meeting with Mr. Jim Miller of Chelsea Laboratories and Mr. Al Baker (via conference call) on May
13, 1994. A request for permission to discharge on -site was addressed. The request was denied.
Discharge to the cooling tower was denied by Chelsea citing potential repercussions with new FDA
guidelines.
Both spray irrigation and subsurface disposal were denied citing the potential to spread liability with
regard to potential cleanup if the contaminates were spread to other portions of the property.
14

Since the requests to discharge treated groundwater to the sewer or to allow on -site disposal were denied,
no cost analysis could be made. Therefore, a NPDES permit is required for discharging excess treated
groundwater.
Copies of correspondence with the City of Monroe and with Chelsea Laboratories and Marion Merrell
Dow are provided in Appendix A.
15

V. PROPOSED NPDES DISCHARGE
It is proposed to discharge excess treated recovery water to the culvert under Hastey Road at Longitude
80d29'30", Latitude 34d58'51". An excerpt from the USGS 7.5 minute Monroe and Wingate quadrangles
is provided. Both the proposed discharge point and the discharge pathway are marked. Note that Hastey
Road has been relocated since the last revision of this quadrangle. A current site plan based on a recent
topographic survey is presented showing the current site and proposed facilities for this project. (See
Drawing 2).
The proposed discharge is for a maximum flow rate of 50 gpm (72,000 gpd). It is understood that the
anticipated well yield of this portion of the interim remediation project is 10 to 15 gpm. This request for
50 gpm is made to allow full utilization of the air stripping equipment and allow for increasing well yield
or adding wells as needed.
The proposed design criteria of the air stripping unit is as follows:

equipment will meet the treatment goals.

Subject: Remediation Water Use Ban
Dear Mr. Cashman:
It has come to my attention that a plan has been proposed to remediate prior perchlorethylene
levels of groundwater contamination at the Chelsea Laboratories, Monroe, North Carolina site. After
reviewing the proposed options for use of the water stream after air stripping, I must inform you that it
is not acceptable to Marion Merrell Dow Inc., owner of Chelsea Laboratories to use the remediated
ground water in the Chelsea site cooling tower or as landscape irrigation as you suggest.
As Marion Merrell Dow Environmental, Health and Safety Director, it is my understanding
that the U.S. Food and Drug Administration would find the use of remediated water in the Chelsea
cooling tower unacceptable. The potential for cross contamination of a drug product with the service
cooling water is always under FDA scrutiny and thus is not an acceptable use for the remediated water
stream.
Using the remediated water stream to irrigate the site landscape is not acceptable because a
processing upset could potentially lead to further soil contamination. In this case, the question of
Chelsea's responsibility could complicate the remediation of prior contamination. The prior
contamination occurred during the period of time R.P. Scherer owned and operated this site, and prior
to the purchase by Chelsea Laboratories. Chelsea Laboratories is indemnified by R.P. Scherer for that
prior soil contamination. Possible future contamination could result in confusion as to which party is
responsible for that clean-up and cause Chelsea and MMD to suffer financial harm.
Therefore, use or remediated ground water in the cooling tower, or for landscape irrigation is
unacceptable. It would be our recommendation that the remediated water stream be discharged to the
local publicly owned treatment works or through a NPDES permitted point. If you require further
input, please do not hesitate to give me a call.

Laboraiory Direcwr
As we discussed last Friday, enclosed are preliminary design drawings for the proposed
interim remediation system at the subject facility. I hope to have your input regarding our ideas
prior to presenting this package to Mr. Jim Miller of Chelsea.
In our discussion last Friday, you expressed some _conceuis regarding the use of the
facility's cooling tower and grounds irrigation system as receiving points of the treated
groundwater. At startup, the proposed system has a significant safety factor with respect to
treatment. The estimated total initial flow from the four recovery wells is 12 to 15 gpm, and the
design flow rate for the proposed air stripper is 50 gpm. This air stripper has been sized to
reduce the contaminants of concern to less than detection values at the design flow rate. A
second design advantage is that approximately 70% of the air stripper effluent will be returned
to the air stripper influent for further treatment.

Mr. Al S. Baker, Director
April 18, 1994

If alternate treated water receiving points are not available to operate the system under
optimal conditions, a NPDES permit would be required to discharge the treated water into a
surface water body. This process can be very lengthy. We will approach the local POTW
representative about discharging treated groundwater to the sewer; however, an earlier request
was denied.
We will contact you on Friday, April 22, 1994 to discuss any comments that you may
have and look forward to receiving your comments.

MONROE, NORTH CAROLINA
INTERIM GROUNDWATER REMEDIATION SYSTEM
APRIL 15, 1994
INTRODUCTION
Chelsea Laboratories, Inc. of Monroe, North Carolina is a manufacturer of medicine tablets. This
facility was constructed, owned and operated by R. P. Scherer Corporation in 1976 for the
manufacturing of soft gelatin capsules. Chelsea purchased this facility from R. P. Scherer in
January, 1986 and has operated it since that time.
During cleanup of a diesel fuel spill in July 1992, Chelsea discovered tetrachloroethene (PCE) soil
contamination in the vicinity of the diesel spill area. Chelsea excavated the soil and notified R.
P. Scherer of the contamination. With approval from the North Carolina Department of
Environment, Health, and Natural Resources (NCDEHNR), R. P. Scherer transported the
contaminated soil to an appropriate disposal/treatment facility and initiated a preliminary soil and
groundwater investigation in the area of the PCE contamination. The investigation indicated the
presence of limited PCE contamination in the soil and elevated PCE contamination in the
groundwater at the northeast corner of the building. Attachment "A" presents a summary of the
groundwater analysis.
Based on the findings of a preliminary investigation, R. P. Scherer and NCDEHNR's Inactive
Hazardous Sites Branch determined the need for a Remedial Investigation to delineate the extent
of soil and groundwater contamination, and design and implement appropriate remedial action.
The site was designated number 51 on the Inactive Hazardous Waste Sites Priority List dated
March 11, 1994.

The purpose of the Interim Remediation System is to address on -site groundwater contamination
identified to date. Upon completion of the Remedial Investigation, treatment of off -site
groundwater may be required.
The proposed Interim Remediation System will consist of converting four monitoring wells into
pumping or recovery wells; installing an air stripping unit to treat contaminated groundwater;
constructing an infiltration gallery to introduce treated groundwater upgradient of the recovery
wells and area of contamination; converting an existing monitoring well to a shallow injection well
upgradient of the infiltration gallery and upgradient of the contaminant plume; and maintaining
a background monitoring well upgradient of the injection well. Refer to Drawing 2 for a
preliminary site plan showing the proposed location of these facilities.
INTERIM GROUNDWATER REMEDIATION SYSTEM
The proposed groundwater remediation system is presented schematically in Drawing 1. The unit
processes include:
Four pumping/recovery wells
Air stripping unit
Gravity settling chamber
Finished water pump station including high and low head pumps
Shallow injection well
Infiltration gallery.
Attachment "B" shows the anticipated operation of the system. When in operation, treated water
in the infiltration gallery and injection well will raise the water table in that area while the
recovery wells will create a depression in the water table. The resulting hydraulic profile should
further influence groundwater flow toward the recovery wells.
2

Monitoring wells MW-2, MW-3, MW-4, and MW-5 will be converted to groundwater recovery
wells. This will require reaming monitoring wells MW-3, MW-4, and MW-6 to 6 inches in
diameter and installing pumps, controls, and piping. Well MW-2 is constructed with a stainless
steel casing and will be fitted with a smaller pump. The above ground equipment for each well
will be housed in a fiberglass enclosure with approximate dimensions measuring 42 inches by 36
inches by 42 inches tall. The enclosure will be hinged to allow access to the pumping equipment.
The well pumps are controlled by well water elevation with level probes. In addition, float
switches at the finished water sump will control pump operation to prevent overfilling of the
sump.
Contaminated groundwater recovered by the pumping wells will be pumped to a low profile, skid -
mounted air stripper. The air stripper will be housed in a 20 foot by 30 foot metal building. This
building could also serve as the operator's office, record keeping and general storage area for the
remediation project. As a convenience, flow meters for the pumping wells and some pump
controls could be installed inside the building.
The air stripper will be sized for a 50 gpm flow rate and will include a blower, prewired controls,
control panel, and gravity discharge. The PCE concentrations should be reduced to less than
0.002 mg/l. The preliminary design criteria for the air stripper is presented below:

Naturally occurring iron in the groundwater may be oxidized by the air stripper and precipitate.
A settling tank will be provided downstream of the air stripping unit to allow for settling of the
oxidized iron and other sand or sediment that may be in the recovery water. This will reduce
potential impacts on downstream reuses of the treated groundwater.
Treated water from the air stripper and gravity settler will flow to a pumping station. The pump
station will be supplied with a low head submersible type pump and a high head staged pump. The
low head pump will pump treated groundwater to the shallow injection well and infiltration
gallery. In the event these options can not accommodate the total flow from the treatment unit,
treated water can be recirculated to the air stripper.
This system may produce and treat more water than can be returned via the shallow injection well
and infiltration gallery. Therefore, contingencies for alternate reuse options must be made. The
high head pump will be available to reuse excess treated water for make-up water for the cooling
tower, or for supplemental water for the irrigation system.
The low head pump will be controlled by mercury float switches with low level off and high level
4

on switch points. The high head pump will operate off a pressure switch located at the pressure
tank with a low level off switch in the sump to prevent the pump from running dry.
The infiltration gallery is two 150-foot long parallel pipes surrounded by stone. The piping
material is perforated corrugated ABS plastic pipe (commonly referred to as French drain). This
pipe will be installed in a 6-foot wide trench excavated to the bedrock layer (approximate elevation
980 feet MSL). The pipe will be installed with "full envelope" bedding using 3/4 inch diameter
washed stone. This will allow the treated water to percolate from the pipes and into the
surrounding soil. The bedding will be approximately 2 feet deep. The remainder of the trench will
be backfilled with suitable material. The infiltration gallery will be located as shown on Drawing
2.
Flow to the infiltration gallery will be controlled with a float valve located in a sump. The float
valve would close when the level of water in the infiltration gallery reaches a predetermined
elevation.
Monitoring well MW-6 will be converted into a shallow injection well. Treated water will be
pumped to the shallow injection well. A solenoid valve, paced by electrode level probes, will
control the flow to the shallow injection well. The purpose of the injection well is to raise the
hydraulic gradient in the well vicinity and influence the groundwater flow direction toward the
recovery wells.
If either the solenoid valve or electrode fails, a well overflow line will return the excess water to
the pump station sump.
5

OTHER ITEMS
As mentioned above, the recovery wells may produce more water than the infiltration gallery and
shallow injection well can accept. This is due in part to the permeability and transmissivity of the
soils on site. As a result, the system may produce excessive water which must be handled. At this
time, obtaining an NPDES Discharge Permit to release the excessive water is not desirable. This
process is time consuming, could result in additional monitoring of the discharged water stream,
and may require further treatment prior to release. Additionally, direct discharge to a stream is
discouraged by NCDEHNR.
One option is to use excess water as make-up water for the cooling tower. The high head pump
will be sized adequately to match the line pressure requirements of the cooling tower. A supply
line from the treated water pump station would be tied to the cooling tower supply line in such
a manner as to allow the treated water to be the primary water and the plant water supply to be
the supplemental source.
Another option is to use the excess water in the lawn irrigation system. It is our understanding that
the existing irrigation system is not in use at the present time.
During construction of the infiltration gallery, a portion of the soils excavated may contain
elevated levels of PCE. It is estimated that approximately 150 CY of material may be generated.
NCDEHNR has been informally contacted to determine if the excavated soil containing PCE can
be used as backfill for the infiltration gallery. NCDEHNR would not commit to a definitive
position on this issue. As a result, two options have been given preliminary consideration. The
first option is to haul the contaminated soil to the Pinewood, South Carolina landfill operated by
0

Laidlaw.
The second option is to treat the soil on site. One method is to stockpile the contaminated soil in
roll -off containers. The bottom of the roll -off container will be filled with gravel and will have
air diffuser piping. A blower or vacuum pump would be connected to the diffuser to force air
through the soil, thus stripping the PCE. This may involve additional permitting.
SYSTEM PERFORMANCE AND EVALUATION
Scheduled sampling of water from the recovery wells, treated water, and water from the
background wells will begin at the time of system start-up. This data will be used to evaluate the
performance of the system and monitor plume movement. The proposed sampling schedule is
presented below:
Effluent Sampling (treated water)
Once a week First 4 weeks
Once a month Next 5 months
Once a quarter thereafter
Influent (from recovery wells MW-2, 3, 4, and 5)
Once a week First 4 weeks
Once a quarter thereafter

RE: Groundwater Remediation Effluent Discharge
2021 East Roosevelt Boulevard
Dear Mr. Cashman:
The City of Monroe has received and reviewed a request on R. P. Scherer's behalf by
Rogers & Callcott Engineers, Inc. to discharge effluent from an air stripper facility,
designed to remove volatile organic chemicals (VOCs) from contaminated
groundwater, into the City of Monroe sanitary sewer system. This request is being
denied for the following reasons:
(1) The City of Monroe Wastewater Treatment Plant was not established for
the purpose of receiving VOC-pretreated wastewater nor is it designed for this
purpose.
(2) According to the data submitted by Rogers & Callcott, the effective
removal of VOCs from the groundwater by properly designed treatment facilities
would yield an effluent of quality such that there would be no additional treatment
or benefit gained by passing the effluent through a municipal wastewater treatment
facility.
(3) The wastewater from this groundwater remediation facility would yield a
very low revenue return to the City of Monroe and impose very significant risks, or
potential costs. A discharge of ineffectively treated VOCs through the City's plant
could cause treatment inhibition, effluent permit violations, and sludge
contamination. The City does not have the expertise to properly permit and monitor
this type of discharge, nor do we have structures in place to effectively manage this
type of risk.

If you have any questions, please call me at [phone].

Monroe, Union County, North Carolina
R & C Project Number 93-121
Dear Mr. Frederick:
Groundwater analysis at the referenced site have demonstrated some contamination with organic
solvents. Rogers and Callcott Engineers is working for R.P. Scherer to design a remediation system to recover
and treat the contaminated groundwater. The treatment system is being designed to remove volatile organic
compounds (VOC's) to below current detection limits of 0.002 mg/l.
Earlier this year a request was made to yout office regarding the discharge of small quantities of
untreated drilling water collected during site assessment activities (Maalouf to Hinson, dated January 11, 1994).
That request was denied on the basis that the worst sample of groundwater was contaminated with hydrocarbons
(Frederick to Maalouf, dated January 24, 1994).
Since the previous request was for permission to discharge untreated drilling water, it is kindly requested
that your office consider accepting groundwater that has been treated to remove the VOC's of concern to less
than drinking water standards.
The proposed interim groundwater remediation system will consist of four (4) recovery wells that
produce a peak combined flow of 15 gpm. Under normal operation, the anticipated average total flow from
these wells is 8 to 12 gpm. This ground water will be treated with an air stripper, which has a design capacity
of 50 gpm, to remove the VOC's. Enclosed is a table which shows the concentration of the various pollutants
found in each recovery well, the estimated well yield, the estimated composite concentration of the various
pollutants in the combined flow from all the wells, the influent design concentration for each pollutant at the
air stripper and the design effluent requirement for the air stripper. It is noted that a recycle loop wi* be
;;designed into this treatment system, which will allow a portion of the treated groundwater to be recirculated
through the air stripper to further enhance treatment efficiency. Also, mechanical safeguards will be
designed into the treatment system to shut down the well pumps in the event of an air stripper failure.

Mr. Tom L. Frederick

The current plan is to inject a portion of the treated groundwater into the contaminated aquifer, in order
to expedite this remediation effort. It is anticipated that 3 to 5 gpm of the treated groundwater can be returned
to the aquifer, so the balance of the treated water must be disposed otherwise. The options available for
disposal of this treated water are very limited; therefore, your decision concerning this request to discharge
excess treated groundwater to the municipal sewer system is very important to the remediation efforts at the
Chelsea facility.
Since we are in the design phase of this project, it would be most helpful if this request could be
considered at your earliest convenience. If there are any questions or if we need to complete appropriate
application forms, please advise.
Thank you for your consideration and we look forward to hearing from you soon.

RE: Request for Groundwater Well Discharge to City Sewer
Dear Mr. Maalouf:
The City of Monroe has reviewed your request to discharge up to 165 gallons per day of
groundwater from the Chelsea Laboratory site purged during well drilling for an investigation
of possible groundwater contamination.
Regrettably, the City of Monroe cannot grant your request. The City does not have the
expertise on staff to consider a request of this type at the present time. Although the State
will advise you that the groundwater can be discharged to a municipal sewer with permission
from the local authority, the State has very specific rules which require that municipal sewer
systems regulate wastewater to prevent discharges which may inhibit biological treatment
operations, pass through the treatment plant and violate effluent standards, or contaminate
sludge. The analysis you have provided contains the presence of EPA priority pollutants.
We are unable to determine the potential effects of this discharge on our system.
I trust that you understand our position on this matter. Please contact me if you have any
questions.
Respectfully,

Dear Mr. Hinson:
Rogers & Callcott Engineers is conducting a groundwater
contamination assessment at the Chelsea Laboratories facility in
Monroe. The assessment is being conducted on behalf of the
facility's former owner R. P. Scherer Corporation.
The investigation will consist of installing several
groundwater wells at the facility. A certain volume of water will
be generated during the drilling process. This water is comprised
of city water that is used in the drilling process and groundwater
generated by development and purging of the wells prior to
sampling. Although the exact volume of water generated cannot be
determined at this point, we estimate that a daily average of two
to three 55-gallon drums will be generated over the next few weeks.
A laboratory analysis report of a "worst case" sample is
attached. Volatile organic compounds, mainly tetrachloroehtene,
were detected in this sample. The sample was collected from a
monitoring well located at the source of contamination; therefore,
the quality of the groundwater to be generated during drilling will
at worst be equivalent to the attached data, and at best will be
uncontaminated groundwater from background locations.
Per our discussion yesterday, the Hazardous Waste Section of
NCDEHNR informed me that the generated groundwater from this
investigation can be discharged into an on -site treatment plant
pending approval of the local sewer authority. Therefore, please
consider this letter as a written request for the City of Monroe's
approval to temporarily discharge groundwater generated during
assessment activities at the Chelsea site into the on -site

wastewater treatment plant. A groundwater treatment system will be
constructed on -site in the near future for long term remediation;
therefore, our discharge request needs only be valid for assessment
activities until such a system is constructed. Records of the
actual volume of water and dates of discharge will be kept for your
review.
We appreciate your prompt review of this application and hope
to receive your written approval prior to starting field
activities, which are scheduled for January 18, 1994. In order to
avoid delays, I will contact you on Thursday, January 13 to answer
any questions you may have. If you have any questions in the

Project Summary
Treatability of RCRA Compounds
in a BOD/Nitrification Wastewater
Treatment System with Dual
Media Filtration
Steven I. Safferman and Sanjoy K. Bhattacharya
The discharge of nitrogen and poten-
tially toxic or hazardous organic com-
lpounds to the environment from
!wastewater treatment plants has come
under scrutiny In recent years. Of
specific concern are the many organic
compounds excluded from Resource
Conservation and Recovery Act (RCRA)
regulations if they are discharged into a
wastewater treatment plant. This study
investigated the treatability and fate of 28
organic RCRA compounds in a combined
organic removal and nitrification process
and secondary effluent gravity filtration.
A 3.8 L/min pilot -scale extended aeration
wastewater treatment system with dual
media effluent filter was used for the
study. With a total concentration of ap-
proximately 1.5 mg/L organics (sum of
the concentration of all 28 RCRA com-
pounds) in the aeration basin, most of the
compounds were removed to below
detectable limits by secondary treatment
under either acclimated or unacclimated
conditions. The effectiveness of the ef-
fluent filter to remove organic com-
pounds could not be assessed as most of
the compounds entering the filter were
already reduced to below detectable
levels. Ammonia removal was sig-
nificantly Impaired at a total concentra-
tion of 19.2 mg/L organics in the aeration
basin. COD reduction was apparently not
inhibited at any of the spike concentra-
tions tested.
This Project Summary was developed
by EPA's Risk Reduction Engineering
Laboratory, Cincinnati, OH, to announce
key findings of the research project that
is fully documented In a separate report
of the same title (see Project Report or-
dering Information at back).
Introduction
The effects of discharging hazardous
wastes into the environment without ade-
quate treatment have become of increasing
concern to regulatory agencies and the
scientific community. Some of the com-
pounds associated with hazardous waste
can accumulate in the environment and are
mutagenic, teratogenic, or carcinogenic.
They can also volatilize into the atmosphere,
cause ground water contamination, and in-
hibit wastewater treatment processes.
Under the domestic sewage exclusion
statement, certain RCRA-regulated com-
pounds are exempt from RCRA regulations
if discharged into wastewater treatment
plants. Such compounds are assumed to
be treated adequately by the facility and to
cause no process interference.
The treatability of these compounds must
be assessed and their effect on the treatment
process understood. The specific objective
of this study was to investigate the treatability
and fate of selected organic RCRA com-
pounds in a combination BOD/nitrification
process. The importance of this objective is
realized when the recent changes in regula-
tions to require reduced ammonia discharge
are considered. Many wastewater treatment
plants that previously did not stabilize
nitrogen may now be required to do so.
One common means of achieving both
nitrification and carbonaceous BOD
removal is with an extended aeration sys-

tem. In this study, 28 RCRA compounds
with a broad range of properties were spiked
into a pilot -scale extended aeration system
with dual media secondary effluent filters to
achieve the following goals:
• investigate the treatability and fate of the
selected RCRA toxics in the nitrification
process for both acclimated and unac-
climated conditions and
• determine the effectiveness of effluent
dual media filtration to remove the com-
posite RCRA toxics.
Procedure
To carry out the objectives of this project,
two 3.78 L/min pilot -scale extended aeration
wastewater treatment plants with dual media
secondary effluent filters were constructed
and operated at the U.S. Environmental
Protection Agency (EPA) Test and Evalua-
tion Facility (T&E) in Cincinnati, Ohio. The
hydraulic retention time of each system was
16.8 hr and the average solids retention time
was 21 days.
The influent was primary effluent from the
Mill Creek Wastewater Treatment Plant in
Cincinnati, Ohio; primary effluent from one
Of two pilot -scale conventional activated
sludge systems at the T&E facility; or a com-
bination of both. Because the conventional
Pilot systems were being spiked with the
RCRA compounds, this design allowed
spiking of the extended aeration systems
continuously or intermittently at various
toxics concentrations.
The 28 RCRA compounds were spiked
into the conventional pilot systems at several
different concentrations ranging from 0.25 to
1.0 mg/L of each organic. These com-
pounds were selected to ensure a good
representation of RCRA compounds with a
wide range of properties. The resulting ran-
ges were Henry's coefficient: 0.0o0o to
0.944; and log octanol/water coefficient:
0.07 to 8.69.
The three phased project studied (1)
process interference caused by organic
RCRA compounds, (2) treatability and fate
of organic RCRA compounds, and (3)
removal of organic RCRA compounds by
dual media effluent filtration. A description
of the procedures for each phase follows.
Phase 1, Process Interference
In this phase, the effect of the 28 RCRA
compounds on the ability of a pilot -scale
extended aeration wastewater treatment
plant to adequately treat the wastewater was
investigated. Chemical oxygen demand
(COD), nitrate, ammonia, and total Kjeldahl
nitrogen (TKN) were the primary process
control variables used to evaluate the
system's performance.
The performance was compared under
five different spike conditions:
• baseline, system performance before any
spike had been added;
• total spike concentration of 1.8 mg/L,
which was calculated by summing the
amount of each compound found from
each event and taking the average of the
three events;
• total spike concentration of 4.8 mg/L,
which were similarly calculated as above;
• total spike concentration of 19.2 mg/L,
which was calculated based on the spike
Pump's setting; and
• discontinuation of spike.
Phase 2, Treatability and Fate
In this phase of the project, the concentra-
tion of the 28 compounds at different stages
of the treatment process were studied. The
influent spike concentration was about 0.1
mg/L for each compound, assuming mini-
mal removal by the primary clarifier. From
the literature and from preliminary opera-
tions, this initial concentration was selected
so as not to cause any process interference
to the system.
To investigate the removal and fate of the
compounds under both acclimated and un-
acclimated conditions, one of the extended
aeration systems was spiked continuously
with the RCRA compounds to allow the
microorganisms to become acclimated to
the toxics. The other system was spiked
only during sampling events so that the
microorganisms would not become ac-
climated.
Data were obtained from three sampling
events, each consisting of a 48-hr time
period. For the first 24 hr of each event, the
unacclimated system was spiked with the
RCRA compounds. For each event,
samples were taken every 4 hr and com-
posited for analysis of the RCRA com-
pounds.
Phase 3, Removal by Filtration
In this phase, the efficiency of dual media
effluent filtration to remove organic RCRA
compounds was investigated. To assess
the effectiveness, the concentration of each
compound was measured in the secondary
effluent (before entering the filter) and then
in the filter effluent. Data were obtained for
two secondary effluents:
• secondary effluent obtained from the ac-
climated extended aeration system, which
was being spiked at a total toxics con-
centration into the aeration basin of 1.8
mg/L and
• secondary effluent obtained from the ac-
climated conventional system at the T&E
facility, which was being spiked at a total
toxics concentration into the aeration
basin of 4.8 mg/L.
Samples were collected for RCRA com-
pound analysis 11 times: 3 for the extended
aeration system's secondary effluent and 8
for the conventional secondary effluent.
Results and Discussion
Phase 1, Process Interference
The process control parameters of COD,
ammonia, and nitrate were used to gauge
the process interference caused by the
spiked RCRA compounds during Phase 1 of
this study. Four spike concentrations were
tested. Figure 1 shows the percent removal
of TKN and ammonia and the increase in
nitrate resulting from secondary treatment
for each spike concentration. The trends in
the figure seem to indicate that nitrification
was inhibited even at a low spike concentra-
tion, although ammonia reduction by secon-
dary treatment was not inhibited until spike
concentrations between 4.8 and 19.2 mg/L
were reached. After spiking ceased,
nitrification returned to its pre -spiking level
within a few days. COD removal did not
seem to be adversely affected by the spike
even at the highest composite concentration
tested, 19.2 mg/L.
To assess the interference of the RCRA
compounds on an unacclimated system, a
parallel system was intermittently spiked.
The average total spike concentration (total
concentration of 28 compounds) was 1.3
mg/L for three shock loadings, which ap-
parently caused no inhibition of COD or am-
monia reduction.
Phase 2, Treatability and Fate
The treatability and fate of the 28 organic
RCRA compounds spiked in Phase 1 at a
total concentration of 1.8 mg/L was inves-
tigated in Phase 2 for acclimated and unac-
climated conditions. Composite samples of
aeration basin influent, secondary clarifier
effluent, and recycled activated sludge were
collected three times for analysis of the com-
pounds.
For the three sampling events from the
acclimated system, all of the compounds,
for which valid data were collected, were
removed to below detectable limits (Table
1). The variations in the aeration basin in-
fluent were probably caused by different
removal rates of the compounds in the
primary clarifier, background concentra-

For the three sampling events for the un-
acclimated system (spiked intermittently at
an average total concentration of 1.3 mg/L),
only four compounds had removals below
95%: 1,1,2-trichloroethane, bis(2-ethylhexyo
phthalate, toluene, and nitrobenzene (Table
2). The unacclimated conditions apparently
did not result in a significant reduction in
removal efficiency at the RCRA compound's
concentration tested.
Phase 3, Removal by Filtration
The secondary effluent from both the ac-
climated and unacclimated nitrification sys-
tems were passed through dual media
effluent filters for the first 62 days of the
project. The secondary effluent from the
conventional system was passed through
one of the filters after day 62. Eleven
analyses were run for the organic RCRA
compounds going into and coming out of
the filter: three for the nitrification secondary
effluent and the others for the conventional
system.
The filters removed approximately 50°/. of
the total suspended solids for most operat-
ing conditions. Because the secondary ef-
fluent from the nitrification system had very
low concentrations of RCRA compounds,
the effectiveness of the filters could not be
12
assessed for the first 62 days of the project.
Higher concentrations of some of the com-
pounds were present in. the secondary ef-
fluent from the conventional system. The
results indicate acetone, tetrahydrofuran,
tetrachloroethylene, and phenol had sig-
nificant removals by the filters (Table 3).
Values for these compounds, however,
were found only in Event 9. The remaining
compounds, for both Events 4 and 9, had
removals under 20%.
Conclusions
The following conclusions were drawn
from this study:
e COD removal was not inhibited at the
tested composite spike concentrations of
1.8, 4.8 (measured by summing the con-
centrations of all 28 compounds into the
aeration basin), and 19.2 mg/L (estimated
based on pump setting).
e Ammonia removal was significantly in-
hibited at the composite spike concentra-
tion of 19.2 mg/L (the sum of the
concentrations of all 28 compounds into
the aeration basin).
e Almost 100% of the spiked organic RCRA
compounds were removed when the
spike concentration was at 1.8 mg/L (the
14 16 18
sum of the concentrations of all 28 com-
pounds into the aeration basin) for the
acclimated condition and 1.3 mg/Lfor the
unacclimated condition.
e Adsorption did not appear to be a principal
mechanism for the removal of the RCRA
compounds.
Recommendations
This study indicates that an extended
aeration wastewater treatment plant can ef-
fectively remove low concentrations of or-
ganic RCRA compounds without interfering
with BOD, ammonia, and suspended solids
removal. Because of the many different
combinations and concentrations of RCRA
compounds that could be expected in the
influent to a municipal wastewater treatment
plant, a correlation between this study and a
real Irfe situation is risky. Further studies and
surveys of actual extended aeration was-
tewater treatment plants are required to con-
firm these study findings, to determine if or
when harmful by-products are produced,
and to find the compound's removal
mechanism.

Contract No. 6M3-4038 by the University of

"EPA Project Summary
Removal and Fate of
RCRA and CERCLA Toxic
Organic Pollutants in
Wastewater Treatment
Sanjoy K. Bhattacharya, Rao V. R. Angara, Dolloff F. Bishop, Jr.,
Richard A. Dobbs, and Barry M. Austern
Two separate studies were con-
ducted to investigate the removal and
fate of 28 selected Resource Conser-
vation and Recovery Act (RCRA)
compounds (0.25 mg/L of each
compound) and 19 selected Compre-
hensive Environmental Response,
Compensation, and Liability Act
(CERCLA) compounds (0.5 mg/L of
each compound) in conventional
activated sludge treatment. In each
study, two pilot -scale (35 gpm) acti-
vated sludge systems (Solids Reten-
tion Time (SRT): 4 days for RCRA
study and 8 days for CERCLA study)
were operated in parallel at The U.S.
Environmental Protection Agency's
Test & Evaluation Facility in
Cincinnati, Ohio. One system was
spiked continuously with either RCRA
or CERCLA toxics to produce an
acclimated biomass; the other was
spiked intermittently with the same
toxics and sampled to determine
performance under unacclimated
conditions. The selected RCRA or
CERCLA compounds did not cause
any adverse effects on Chemical
Oxygen Demand (COD) and
Suspended Solids (SS) removals. The
concentrations of organics (RCRA
study) in the air emissions indicated
that the chlorinated aliphatic solvents
were essentially volatilized into the
plant air emission stream, whereas
the aromatic volatile benzenes were
substantially degraded. Additional
work is planned to attempt to reduce
the analytical variability encountered
in these studies.
This Project Summary was devel-
oped by EPA's Risk Reduction Engi-
neering Laboratory, Cincinnati, OH, to
announce key findings of the research
project that is fully documented in a
separate report of the same title (see
Project Report ordering information at
back).
Introduction
A survey of publicly owned treatment
works (POTW) showed that concentration
of priority pollutants in the influent
wastewater to many of these plants
exceeded the allowable concentrations
for these chemicals. In a study of the fate
of 22 toxic organics in wastewater
treatment plants, researchers reported
that a typical POTW significantly (up to
90%) reduced the concentrations of most
of these compounds. Certain compounds
were, however, present in the activated
sludge effluent in relatively high (20-30
ug/L) concentration. In an investigation of
the comparative removal of priority
pollutants by six biological and physical -
chemical treatment processes, research-
ers reported that the activated sludge
process provided best results. A further
review of the literature indicated that only
limited data are available for many
priority pollutants.
In the study summarized here, the
removal and fate of selected RCRA and
CERCLA toxic organic pollutants were
evaluated with two pilot -scale activated

sludge systems fed municipal waste-
water. The 28 RCRA (semi -volatile and
volatile) and 19 CERCLA (semi -volatile
only) chemicals (Table 1) were spiked
into the raw wastewater in two separate
test periods.
Experimental Systems and
Testing Approach
The two activated sludge systems
were operated at a flow rate of 35 gpm
and a hydraulic retention time (HRT) of
7.5 hr. An operational SRT of 4 days was
used in the RCRA study period. In the
CERCLA study period, the SRT was 8
days. Each compound was spiked at
0.25 mg/L for the RCRA study and at 0.5
mg/L for the CERCLA study. The
operating conditions and design char-
acteristics for the two systems used in
the study are given on the next page.
Both RCRA and CERCLA studies were
performed with an acclimated (con-
tinuous addition of toxicants) and an
unacclimated (intermittent spiking of
toxicants) system. These systems were
operated in parallel.
To sample from the air space above
the primary clarifier, the units were
covered and vented through a duct to the

hausting air at 14,000 L/min. The
aeration basin was fitted with an air tight
cover and the off -gas was also vented to
the roof. Air flow in the aeration basins
averaged 5,600 Umin.

(COD, BOD, NH4-N, NO3-N and TKN)
and Gas Chromatography/Mass Spec-
trometry (GC/MS) procedures were used
for the toxic organic compounds. RCRA
samples were analyzed by a contract
laboratory (PEI Associates Inc.,
Cincinnati, OH). Air samples, collected in
stainless steel canisters, were analyzed
by GC/MS. From these data, masses of
each RCRA compound stripped during
the sampling event were calculated.
Sludge and liquid samples were also
analyzed by GC/MS according to
approved USEPA methods. Semi -volatile
RCRA compounds were extracted from
the samples with the use of continuous
liquid -liquid extraction. Prepared portions
of the extracts were injected into the
GC/MS for analysis. The semi -volatile
CERCLA compounds were analyzed
following Method 1625. Analyses were
performed at the EPA's Risk Reduction
Engineering Laboratory (RREL). Details
of the analytical procedures are in the
Project Report.
Three tests (sample collection events)
were performed during the RCRA study
period. For the CERCLA study, 11 tests
were done on the continuously spiked
(acclimated) system and 4 tests on the
intermittently spiked (unacclimated)
system.
Results
The presence of the spiked toxic
organics in the wastewater produced no
major adverse effects on the treatment of
conventional pollutants. Average re-
movals of conventional pollutants in the
Pilot systems during the two studies
were between 94% and 97% for SS and
between 81 % and 88% for COD. In the
RCRA study period, nitrification in the
activated sludge processes produced

average NH4-N reductions between 76%
and 81 % percent. In the CERCLA study,
the NH4-N removal was between 88%
and 98%. The CERCLA toxics (0.5 mg/L)
did interfere with nitrification in the
acclimated system.
Substantial variability occurred in the
reported results with some toxic com-
pounds, especially in the RCRA study
period. Table 2 lists average measured
concentrations of the selected RCRA
organics in wastewater and sludges for
the acclimated system. The difference
between the concentration of most toxics
in the spiked wastewater feed and
primary effluent was very small. The
primary sludge showed enhanced con-
centrations of the two phthalates and
naphthalene along with reduced concen-
trations in primary effluent; this indicated
adsorption onto sludge solids. Four
compounds (tetrahydrofuran, 1,2 dichlo-
roethane, methylene chloride, and 1,1,2-
trichlordethane) were present in the
secondary effluent stream in high con-
centrations (between 95 and 140 ug/L);
this indicated these organics were poorly
removed. Five other compounds (cyclo-
hexanone, furfural, 2,4-dimethyl phenol,
2,4-dinitrophenol and 4-nitrophenol) were
not evaluated because of inconsistent
results. The average removals of the
toxic compounds in the RCRA study are
summarized (Table 3). The removal of
RCRA organics with primary treatment
was between 3% and 44%. The total
removals were between 37% and 99%.
The calculated percent stripped for the
individual volatile compounds varied from
1 % to 139%. No air analyses were
performed for the semivolatiles. Biode-
gradation of a compound was estimated
by subtracting the measured removals by
adsorption and stripping of the compound
from the total removal. The estimated
biodegradation was between -42% and
97%. A negative biodegradation indicated
inconsistent mass balance and the prob-
lems of estimating biodegradation with
this approach. Biodegradation appeared
to be the predominant removal mecha-
nism for the polar solvents and the
aromatic volatiles (e.g., toluene: 72%,
xylenes: 66%, chlorobenzenes: 60%).
The unacclimated system (e.g., biodeg-
radation of toluene: 56%) showed similar
results, and no significant advantage of
acclimation was observed.
Table 4 lists the average concentra-
tions of the CERCLA organics. Five
compounds showed high concentrations
-in the -secondary effluents: 1,2,4-trichlo-
robenzene; 89 ug/L; 2,6-dinitrotoluene;
125 ug/L; p-cresol; 156 ug/L; lindane; 198
ug/L; and dieldrin; 99 ug/L. The average
removals of the toxic compounds in the
CERCLA study are summarized in Table
5. The removals of CERCLA organics in
primary treatment with the acclimated
system was between 4% and 79%. The
total removal varied between 56% and
98%. Biodegradation was estimated by
subtracting the removal by adsorption
from the total removal of a particular
compound. The extent of biodegradation
varied between 28% and 100%. The
unacclimated system also exhibited
similar removals. Biodegradation values
were similar for both acclimated and
unacclimated systems (e.g., naphthalene:
79% and dimethyl phthalate: 85%). As in
the RCRA study, no significant advantage
of acclimation was observed for the
CERCLA compounds. In the CERCLA
study period, the amounts of organics
found in the complex primary sludge
samples were substantially lower than the
measured removals across the primary
process. Because of the analytical
variability encountered in these studies,
additional work has been planned.
Conclusions
The following conclusions were drawn
from this study:
1. The polar solvents and aromatic vola-
tiles were biodegraded to a great
extent. For example, toluene ex-
hibited 72% and total xylene showed
66% biodegradation.
2. A significant amount of chlorinated
aliphatic solvents may be volatilized
from an activated sludge system.
The percent stripped varied between
1 % and 139%.
3. Pesticides (lindane and dieldrin) were
removed both by adsorption onto
sludge and by biodegradation in the
secondary tank.
The full report was submitted in partial
fulfillment of Contract No. 68-03-4038 by
the University of Cincinnati under the
sponsorship of the U.S. Environmental
Protection Agency.

We have estimated the loading rate of the infiltration gallery as follows. Based on
standard design for septic tank drain fields, under optimal conditions, a loading rate of 0.5 gpd
per square foot is commonly used. Since this infiltration gallery will be placed on rock, an
optimistic loading rate of 0.25 gpd per square foot is used. The gallery loading is given below.
Loading = (0.25 gpd/sf) x (150 ft x 6 ft) = 225 gpd

Interim Groundwater Remediation System
Sequence of Operation
The proposed Interim Remediation System will consist of converting four monitoring wells into
pumping or recovery wells; installing an air stripping unit to treat contaminated groundwater;
constructing an infiltration gallery to introduce treated groundwater upgradient of the recovery
wells and area of contamination; and maintaining a background monitoring well upgradient of
the shallow injection well.
The proposed groundwater remediation system is presented schematically in Drawing 1 (P & I
Diagram); and in the attached plans and specifications. The unit processes include:
Four pumping/recovery wells
Air stripping unit
Gravity settling chamber
Finished water pump station
Infiltration gallery.
The figure found on the following page is a schematic of the hydraulic concept of the system.
When in operation, treated water in the infiltration gallery and injection well will raise the water
table in that area while the recovery wells will create a depression in the water table. The
resulting hydraulic profile should further influence groundwater flow toward the recovery wells.
Pumping Wells
Monitoring wells MW-2, MW-3, MW-4, and MW-5 will be converted to groundwater recovery
wells. This will require reaming monitoring wells MW-3, MW-4, and MW-5 to 6 inches in
diameter and installing pumps, controls, and piping. Well MW-2 is constructed with a 2-inch
diameter stainless steel casing and will be fitted with a smaller pump.
The well pumps will be controlled by well water elevation with level probes. In addition, float
switches at the finished water sump will control pump operation to prevent overfilling of the
sump.
Anticipated well yields observed during well drilling and development are as follows:
MW-2
1 gpm
MW-3
3 gpm
MW-4
3 gpm
MW-5
5 gpm
Total
12 gpm

Air Stripping
Contaminated groundwater recovered by the pumping wells will be pumped to a low profile,
skid -mounted air stripper. The air stripper will be sized for 50 gpm. This will allow full
utilization of the air stripper and flexibility to accommodate future wells as needed during
progression of site remediation. The air stripper will be housed in a 20 foot by 30 foot metal
building. This building can also serve as the operator's office, record keeping and general storage
area for the remediation project. As a convenience, flow meters for the pumping wells and some
pump controls may be installed inside the building.
The air stripper will include a blower, prewired controls, control panel, and gravity discharge.
The PCE concentrations should be reduced to less than 0.002 mg/l. The preliminary design
criteria for the air stripper is presented below:

The attached table shows the weighted average of the air stripper influent.
Gravity Settling
Naturally occurring iron in the groundwater may be oxidized by the air stripper and precipitate.
A settling tank will be provided downstream of the air stripping unit to allow for settling of the
oxidized iron and other sand or sediment that may be in the recovery water. The tank will be 6'
x 8' x 4' deep (1,400 gallons). This will provide a detention time of 28 minutes at 50 gpm or
almost 2 hours at 12 gpm. It is proposed to provide a precast concrete or a poured in place
concrete tank with a high density polyethylene (HDPE) liner.
Finished Water Pumping
Treated water from the air stripper and gravity settler will flow to a pumping station. The pump
station will be supplied with duplex submersible pumps. The pump station will pump treated
groundwater to the infiltration gallery. In the event these options can not accommodate the total
flow from the treatment unit, treated water can be recirculated to the air stripper.
This system may produce and treat more water than can be returned via the shallow injection
well and infiltration gallery. Therefore, a surface discharge is sought. An NPDES permit will
allow for optimal operation of the system. Operation of the recovery wells can continue while
allowing time for the treated water in the infiltration gallery to infiltrate thus expediting the

remediation process.
The system will be set to pump to recirculate to the air stripper. A throttling valve will control
the recirculation rate. A valve arrangement (discussed below) will control the flow to the
infiltration gallery. When flow backs up in the pump station sump, a solenoid valve on the
NPDES discharge line will be actuated and flow will be released through this line. Note that this
will occur only when flow cannot be accommodated by the infiltration gallery or the recirculation
line. Refer to the attached diagram.
The pump station sump will be either a HDPE or HDPE-lined manhole.
Infiltration Gallery
To enhance the clean up effort, an infiltration gallery is proposed as and integral part of the
overall remediation system. The infiltration gallery will reintroduce treated water to the area of
contamination raising the head in that area. This water should travel the same path through the
fractures as the contaminant. As a result, the additional head and water supply from the
infiltration gallery should enhance the recovery of contaminants by the pumping wells.
The infiltration gallery will consist of two 150-foot long parallel pipes surrounded by stone. The
piping material will be perforated corrugated ABS plastic pipe (commonly referred to as French
drain). This pipe will be installed in a 6-foot wide trench excavated to the bedrock layer
(approximate elevation 980 feet MSL). The pipe will be installed with "full envelope" bedding
using 3/4 inch diameter washed stone. This will allow the treated water to percolate from the
pipes and into the surrounding formation. The bedding will be approximately 2 feet deep. The
remainder of the trench will be backfilled with suitable material. The infiltration gallery will be
located as shown on Drawing 2.
Flow to the infiltration gallery and the head on the infiltration gallery will be controlled with a
float valve located in a sump. The float valve would close when the level of water in the
infiltration gallery reaches a predetermined elevation. A solenoid valve and mercury float switch
will be provided as a backup to the float valve. It is important to control the head on the
infiltration gallery so that reinjected water will not seep through the toe of the slope to the north
of the infiltration gallery.
System Piping
All piping with the exception of the well head piping, piping inside the equipment building,
piping near the injection well encasement, and well head piping at the infiltration gallery will be
HDPE - PE 3408 piping.

SECTION 2B
EXCAVATION, FILLING AND GRADING
1. SCOPE: Work consists of all necessary site grading,
structure excavation and backfill, trench excavation and backfill,
on -site road and drive grading, borrow, disposal of excess
material, cleanup, dressing off, shoring, and sheathing work as
shown on the plans and specified herein.
2. GENERAL: All excavation and grading shall be confined
to construction area as shown on plans, and shall be done in an
approved manner with proper equipment. Excavation, filling and
grading work shall be suspended during rain and inclement weather,
or when unsatisfactory field conditions are encountered, unless
otherwise directed by Engineer. At all times during constructions,
Contractor shall maintain proper drainage in construction area.
(a) Classification of Earthwork: All excavation will
be unclassified, for payment purposes, unless otherwise specified.
Where rock excavation is separately classified, solid rock shall be
defined and paid for as described in Section 2B-1.
(b) Existing Utilities: Contractor shall take every
precaution to protect existing utility services from damage during
construction operations. If damage occurs, repairs shall be made
promptly at the contractor's expense. All repair work shall be
satisfactory to Engineer and Owner of utility.
1) When interruptions of existing utilities occur,
temporary service shall be provided as approved by Engineer.
3. STRUCTURE EXCAVATION AND BACKFILL:
(a) Structure Excavation shall be made at locations
shown on plans and to exact subgrade required. Bottom of
excavations shall be level and in firm, solid material, with soft
material or voids treated as specified below. Excavated areas
shall be kept free of water by the Contractor during construction
period. Water shall be controlled by the Contractor as needed
until the structure is accepted and placed in operation.
Groundwater shall be kept a minimum of 2 feet below the bottom of
the foundation level during construction. The Contractor shall
take whatever action is needed to control surface water and
groundwater, including gravel lined ditches, sumps, pumps,
underdrain piping systems with pumps, or other methods which will
allow completion of the work in a dry condition. Where earth will
stand, footing trenches may be cut to exact size of footings;
otherwise, forms shall be used.
2B-1

1) Where necessary, sides of excavation shall be
shored and sheathed, or cofferdams built, as required for
protection of work and personnel. Where blasting is required, it
shall be done by experienced personnel and every needed precaution
taken to protect persons and property from injury.
2) If soft or unsuitable material is encountered
at subgrade elevation, such material shall be removed and replaced
with acceptable compacted earth material, stone or 2000 psi
concrete, as directed by the Engineer. Any other excavation below
grade shall be replaced with good material, stone or concrete at
option of Engineer without additional compensation therefor.
3) If specified depth for foundations proves
insufficient to reach firm ground, Engineer shall be notified and
shall furnish instructions for proceeding with the work. Wherever
footing elevations change; step-downs shall be made at a 2:1 ratio,
unless otherwise shown. Connections between stepdowns shall be of
poured concrete of same cross-section as footing connected.
4) Limit of structure excavation, for payment
purposes where excavation is paid on a unit basis, shall be 3 feet
from outside wall line of structures. Material removed beyond this
limit to facilitate work shall be at Contractor's expense.
(b) Backfill around structures and other facilities
shall be completed as soon as possible.
1) Backfill shall consist of clean acceptable
earth, free from trash, brick bats, wood, large rocks, vegetable
matter and other injurious material. It shall be placed in 6-inch
layers and thoroughly compacted by mechanical tampers with any
subsequent settlement being refilled. Care shall be taken to
protect piping and other utilities during backfill operations.
2) Excessively wet, soupy or mucky material shall
be removed from around structures prior to backfill being placed.
No such material shall be used for backfill purposes.
3) Backfill around non-waterholding structures
shall be completed upon completion of structure above finish grade,
and after all piping has been properly installed and tested.
4) Unless approved by Engineer, structures that
are to contain liquids shall not be backfilled until tested for
leakage. It shall be sole responsibility of Contractor to protect
all structures from damage or floatation prior to backfill being
placed.
2B-2

4. SITE GRADING: Site grading shall conform to grades
indicated by finish contours on plans. Where topsoil, pavement or
other items are shown, rough grade shall be finished to such depth
below finish grade as is necessary to accommodate these items. All
areas where structures are to be built on fill shall be stripped to
such depth as to remove turf, roots, organic matter and other
objectionable materials.
(a) Excavation shall be made to exact elevations,
slopes and limits shown on plans.
(b) Fill shall be constructed of material that is
reasonably free from grass, roots, rock and other objectionable
material. Where natural slopes exceed 3:1, horizontal benches
shall be cut to receive fill material. Slopes of less than 3:1 and
other areas shall be scarified prior to placing fill material.
1) Fill shall be formed of acceptable material
placed in successive layers of not over 8 inches loose thickness
for full width of section where practical. Where rock is excavated
along with other material, it shall be incorporated in fill
sections which are not to support pavement or structures and are
not water bearing dikes. Rock shall be evenly distributed. Rock
fragments larger than 1/8 cu. yd. and rock pockets will not be
allowed. No rock larger than 4 inches in greatest dimension will
be allowed in top 12 inches of fills or slopes. Voids between rock
material shall be well filled with good material, and all rock
shall be covered with at least 6 inches of earth.
2) Material for fill shall be spread evenly and
grading equipment routed over work to obtain uniform compaction.
Fills shall be compacted by approved equipment to 95% of maximum as
established by AASHTO T99 (Standard Proctor), Method A so that
future settlement is avoided. Material that is too dry for
proper compaction shall be moistened by suitable watering devices,
turned and harrowed to distribute moisture and then properly
compacted. When material is too wet for proper compaction,
operations shall cease until such material has sufficiently dried.
Under drives, structures, and all paved areas fill compaction shall
be 95% of maximum using AASHTO T99 (Standard Proctor) Method A.
Payment for tests shall be by the Owner and the Contractor shall
pay for any failed test.
3) Borrow material, as needed, will be provided
from work site or other acceptable source. All borrow material
shall be approved by the Engineer.
(c) Dressing Off: All cuts, fills and slopes shall be
neatly dressed off to required grade or subgrade, as indicated on
plans.
2B-3

(d) Cleanup of site shall be made upon completion of
grading work, or any major part thereof, and all excess material
disposed of to Engineer's satisfaction. Excess material shall be
disposed of and dressed off on the site, or adjacent thereto,
whenever possible.
(e) Topsoil shall consist of a natural loamy soil
suitable as surfacing for lawns or roads, occurring usually in a
surface layer 6 to 18 inches thick. It shall be free from stones,
sticks, weeds, unacceptable grass and other objectionable material.
It may be obtained from graded area, if available, and stockpiled
for future use. Otherwise, Contractor shall provide topsoil from
other sources at his own expense. All topsoil shall be approved by
Engineer.
1) Topsoil shall be placed on entire graded area,
when required by plans, or as directed by Engineer. Topsoil shall
be distributed to a depth of 4 inches, measured loose, and dressed
off neatly to finish grade, with all sticks, weeds and other debris
removed.
5. TRENCH EXCAVATION AND BACKFILL:
(a) Trench Excavation: Trenches for pipe and conduit
shall be dug true to line and grade. Unless otherwise indicated or
specified, trenches shall be of a depth to provide a minimum cover
of 3'-0" over top of pressure lines and 2'-6" over top of conduit.
1) Sides of trenches shall be kept as nearly
vertical as possible. Unless otherwise specified, trenches shall
be between 12 and 18 inches wider at top of pipe than outside
diameter of pipe, plus sheeting where necessary. Where paving is
to be cut, it shall be cut in advance of trenching 1 foot wider
than specified width of trench.
2) Where soil conditions prohibit vertical walls,
trench width shall be as specified above with remainder being held
to least possible width greater than that specified. Where solid
conditions prevent trench excavation without excessive widths, or
where directed by Engineer, sheeting shall be used to support
trench walls.
3) Trench bottoms shall be prepared as follows.
a) Trench bottoms shall be hand graded to
provide uniform and continuous bearing for pipe along its entire
length, with bell holes being dug for pipe bells. No ridges, sags
or under -cutting will be allowed.
2B-4

b) If approved by Engineer and subject to
suitable soil conditions, trench may be excavated a few inches
below established sub -grade and backfilled with select material
(from the excavation, if available), well compacted and so shaped
as to give pipe uniform bearing throughout its length at
established grade. Bell holes shall be dug to relieve bells of
load and to provide for completing joints.
c) Where material at subgrade is unstable,
soft and incapable of supporting pipe, trench shall be excavated
below subgrade, as directed by engineer, and refilled to subgrade
with crusher -run stone or gravel, 1-1/2 inches and down in size,
with minimum amount of infest. Material shall be compacted and
graded so as to provide stable foundation and uniform bearing for
pipe. Bell holes shall be provided as in other types of
foundation.
d) For PVC pipe, foundation material shall be
sand of suitable consistence and gradation.
e) If ground water is encountered in bottom
of trench, material shall be excavated below subgrade sufficiently
to allow a bed of crushed stone or gravel to be placed in which to
bed pipe. Work shall be done as specified for unstable
foundations. Depth of cut below subgrade shall be only the minimum
amount to accomplish the purpose, and shall be as directed by
Engineer. Contractor shall remove accumulated ditch water while
pipe is being laid.
5) All blasting where required shall be done under
personal supervision of a person thoroughly skilled in this class
of work. All necessary measures to protect life and property shall
be taken. Where in close proximity to buildings, transmission
lines, telephone lines or other facilities, timber mats or other
means of preventing damage from flying debris shall be used. Ample
and suitable signals shall be given in proximity to work before
each blast, and on all roads, flagmen shall be placed beyond danger
zone in every direction to warn traffic. Contractor shall be
responsible for all damage resulting from blasting.
a) Backfillina of Trenches shall progress as rapidly as
pipe -laying and testing will permit.
2B-5

1) For all pipelines except sanitary sewer lines,
backfill around pipe and above top of pipe to a depth of at least
12 inches shall be placed by hand in layers not more than 6 inches
thick. Only select material free of stones over 2 inches, hard
lumps, debris and other objectionable material shall be used for
this portion of backfill. As fast as material is placed, it shall
be cut under haunches of pipe with a shovel and thoroughly
compacted with light tamps for full width of trench to provide

- Sequence of Operation Description
Design Calculations
We have estimated the loading rate of the infiltration gallery as follows. Based on
standard design for septic tank drain fields, under optimal conditions, a loading rate of 0.5 gpd
per square foot is commonly used. Since this infiltration gallery will be placed on rock, an
optimistic loading rate of 0.25 gpd per square foot is used. The gallery loading is given below.
Loading = (0.25 gpd/sf) x (150 ft x 6 ft) = 225 gpd

wells and area of contamination; and maintaining a background monitoring well upgradient of
the shallow injection well.
The proposed groundwater remediation system is presented schematically in Drawing I (P & I
Diagram); and in the attached plans and specifications. The unit processes include:
Four pumping/recovery wells
Air stripping unit
Gravity settling chamber
Finished water pump station
Infiltration gallery.
The figure found on the following page is a schematic of the hydraulic concept of the system.
When in operation, treated water in the infiltration gallery and injection well will raise the water
table in that area while the recovery wells will create a depression in the water table. The
resulting hydraulic profile should further influence groundwater flow toward the recovery wells.
Pumping Wells
Monitoring wells MW-2, MW-3, MW-4, and MW-5 will be converted to groundwater recovery
wells. This will require reaming monitoring wells MW-3, MW-4, and MW-5 to 6 inches in
diameter and installing pumps, controls, and piping. Well MW-2 is constructed with a 2-inch
diameter stainless steel casing and will be fitted with a smaller pump.
The well pumps will be controlled by well water elevation with level probes. In addition, float
switches at the finished water sump will control pump operation to prevent overfilling of the
sump.
Anticipated well yields observed during well drilling and development are as follows:
MW-2
1 gpm
MW-3
3 gpm
MW-4
3 gpm
MW-5
5 gpm
Total
12 gpm

Air Stripping
Contaminated groundwater recovered by the pumping wells will be pumped to a low profile,
skid -mounted air stripper. The air stripper will be sized for 50 gpm. This will allow full
utilization of the air stripper and flexibility to accommodate future wells as needed during
progression of site remediation. The air stripper will be housed in a 20 foot by 30 foot metal
building. This building can also serve as the operator's office, record keeping and general storage
area for the remediation project. As a convenience, flow meters for the pumping wells and some
pump controls may be installed inside the building.
The air stripper will include a blower, prewired controls, control panel, and gravity discharge.
The PCE concentrations should be reduced to less than 0.002 mg/l. The preliminary design
criteria for the air stripper is presented below:

The attached table shows the weighted average of the air stripper influent.
Gravity Settling
Naturally occurring iron in the groundwater may be oxidized by the air stripper and precipitate.
A settling tank will be provided downstream of the air stripping unit to allow for settling of the
oxidized iron and other sand or sediment that may be in the recovery water. The tank will be 6'
x 8' x 4' deep (1,400 gallons). This will provide a detention time of 28 minutes at 50 gpm or
almost 2 hours at 12 gpm. It is proposed to provide a precast concrete or a poured in place
concrete tank with a high density polyethylene (HDPE) liner.
Finished Water Pumping
Treated water from the air stripper and gravity settler will flow to a pumping station. The pump
station will be supplied with duplex submersible pumps. The pump station will pump treated
groundwater to the infiltration gallery. In the event these options can not accommodate the total
flow from the treatment unit, treated water can be recirculated to the air stripper.
This system may produce and treat more water than can be returned via the shallow injection
well and infiltration gallery. Therefore, a surface discharge is sought. An NPDES permit will
allow for optimal operation of the system. Operation of the recovery wells can continue while
allowing time for the treated water in the infiltration gallery to infiltrate thus expediting the

remediation process.
The system will be set to pump to recirculate to the air stripper. A throttling valve will control
the recirculation rate. A valve arrangement (discussed below) will control the flow to the
infiltration gallery. When flow backs up in the pump station sump, a solenoid valve on the
NPDES discharge line will be actuated and flow will be released through this line. Note that this
will occur only when flow cannot be accommodated by the infiltration gallery or the recirculation
line. Refer to the attached diagram.
The pump station sump will be either a HDPE or HDPE-lined manhole.
Infiltration Gallery
To enhance the clean up effort, an infiltration gallery is proposed as and integral part of the
overall remediation system. The infiltration gallery will reintroduce treated water to the area of
contamination raising the head in that area. This water should travel the same path through the
fractures as the contaminant. As a result, the additional head and water supply from the
infiltration gallery should enhance the recovery of contaminants by the pumping wells.
The infiltration gallery will consist of two 150-foot long parallel pipes surrounded by stone. The
piping material will be perforated corrugated ABS plastic pipe (commonly referred to as French
drain). This pipe will be installed in a 6-foot wide trench excavated to the bedrock layer
(approximate elevation 980 feet MSL). The pipe will be installed with "full envelope" bedding
using 3/4 inch diameter washed stone. This will allow the treated water to percolate from the
pipes and into the surrounding formation. The bedding will be approximately 2 feet deep. The
remainder of the trench will be backfilled with suitable material. The infiltration gallery will be
located as shown on Drawing 2.
Flow to the infiltration gallery and the head on the infiltration gallery will be controlled with a
float valve located in a sump. The float valve would close when the level of water in the
infiltration gallery reaches a predetermined elevation. A solenoid valve and mercury float switch
will be provided as a backup to the float valve. It is important to control the head on the
infiltration gallery so that reinjected water will not seep through the toe of the slope to the north
of the infiltration gallery.
System Piping
All piping with the exception of the well head piping, piping inside the equipment building,
piping near the injection well encasement, and well head piping at the infiltration gallery will be
HDPE - PE 3408 piping.

Groundwater Remediation
System
Union County
The Division of Environmental Management's Permits and Engineering Unit and Groundwater
Section have completed a preliminary engineering review of the subject application.
The following items must be addressed before we can complete our review:
Information requested by the Groundwater Section
1) Because the injection well is outside the contaminate plume, the injected water will have
to meet 15A NCAC 2L Groundwater standards prior to injection. Therefore, please
demonstrate, submit calculations, etc. that the treatment system can remove the
contaminates to this level.
2) The injection well must act in a closed -loop manner, according to G.S. 143-215.1.A. A
demonstration must be presented that the system will act in a closed -loop manner, i.e.
injected water must be recaptured by the recovery wells.
3) Groundwater Section guidelines specify that the infiltration Gallery's "design flow must
not result in saturated conditions within one vertical foot of the excavated bottom of the
gallery". The system cross-section, provided in the application, indicates that the water
table will mound over the infiltration gallery. The system should be designed to prevent
this situation. Please submit information showing the guidelines will be met.
Information requested by the Permits and Engineering Unit
1) Please provide details of the treatment system, i.e. well pumps and curves, sizes of the
settling chamber and finished water chamber, etc.
P.O. Box 29535, Raleigh, North Carolina 27626-0535 Telephone [phone] FAX [phone]

2) The piping schematic shows a possible discharge to the surface waters of the state in
certain circumstances where the infiltration gallery or injection well cannot handle the
flow. This permit application is for a non -discharge permit for groundwater remediation.
This means that under any circumstances no discharge may occur and the facility cannot
have a bypass to the surface waters as an emergency option. This schematic must be
revised to eliminate any possibility for discharge. If a discharge is possible, the system
should be redesigned to prevent any discharge.
3) Please provide a soil scientist's report of the soils or fractured bedrock to establish an
acceptable loading rate. (see application letter g on page 6 of 9). Also Part V.3 and 4 of
the application (page 3 of 9) needs to be completed based on the soil scientist's report.
4) Please complete Part VII.3 and 4 of the application (page 5 of 9) concerning the buffer
requirements being met and if any substances are added to enhance treatment.
5) Please provide calculations showing how must treated groundwater is being intended for
both the injection well and the infiltration galleries. What percentage of the flow will go
to each?
6) Please provide one additional copy of the corrective action plan and site assessment.
Refer to the subject permit application number when providing the requested information. Prior
to submittal of the additional information, please review pages 5 and 6 of 9 of the application to insure all
the needed information is being or has been submitted. Please submit four copies of all
requested information to my attention at the address below except for P&E number 6.
Also, please note that failure to provide this additional information on or before May 6, 1995 will subject
your application to being returned as incomplete, in accordance with 15A NCAC 2H .0208.
If you have any questions regarding the information requested by the Groundwater Section,
please call Brian Wagner at 91gn33-5083 ext. 406. If your questions concern the information requested
by the Permits and Engineering Unit, please call me at 919/ 733-5083 ext. 544.

Gentlemen:
We would like to thank you and Ms. Carolyn McCaskill for meeting with us on April 27,
1995 to discuss the subject permit applications. I believe that our meeting was very productive
and will speed up the remediation effort on the site. The following is an outline of the points
of decision made during our meeting and subsequent conversations on May 1, 1995. The items
below correspond to the items in your comment letter of April 7, 1995, attached herein for
reference.
I. Groundwater Section Comments:
1- Rogers & Callcott will obtain from the manufacturer of the air stripper calculations that
demonstrate the removal efficiency of the treatment system .

Page 2 of 3
2- The proposed injection well will -be removed from the overall design of the system. This
is due to potential difficulties associated with permitting injection wells. The injection
well would not be necessary considering that DEM will process the NPDES permit
application for the system to handle excess treated groundwater.
3- A component will be added to the system to ensure that treated water infiltrating through
the gallery will not result in saturated conditions within one vertical foot of the excavated
bottom of the gallery. The added component may consist of a shut-off switch installed
in a piezometer adjacent to the infiltration gallery.
II. Permits and Engineering Unit Comments:
1- Details of the treatment system will be provided in the final design package.
2- DEM will reactivate the NPDES permit application for the site to allow discharge of the
excess treated groundwater that cannot be accommodated by the gallery. This will allow
the groundwater recovery system to operate continuously so that a full zone of influence
can develop. Therefore, the discharge component will remain as part of the treatment and
recovery system.
3- A soil scientist report to determine an acceptable loading rate is not applicable for this
site, since the infiltration gallery will be installed directly on top of bedrock and not on
residual soils. In lieu of the soil scientist report, an estimate of infiltration rates will be
made using available hydraulic conductivity data.
4- Buffer requirements are met, and no substances are added io enhance treatment.
5- Since the injection well is no longer a part of the system, all of the recovered and treated
groundwater will be intended for the infiltration gallery. Excess water that cannot be
accommodated by the infiltration gallery will be redirected to the NPDES outfall. The
infiltration rate estimate generated in Item II.3 above will be used to estimate the flow
distribution.
6- An additional copy of the Phase I Remedial Investigation Work Plan and Report is
enclosed.

Additional Information Request
R. P. Scherer Corporation

System
Union County
The Division of Environmental Management's Permits and Engineering Unit and Groundwater
Section have completed a preliminary engineering review of the subject application.
The following items must be addressed before we can complete our review:
Information requested by the Groundwater Section
1) Because the injection well is outside the contaminate plume, the injected water will have
to meet 15A NCAC 2L Groundwater standards prior to injection. Therefore, please
demonstrate, submit calculations, etc. that the treatment system can remove the
contaminates to this level.
2) The injection well must act in a closed -loop manner, according to G.S. 143-215.1.A. A
demonstration must be presented that the system will act in a closed -loop manner, i.e.
injected water must be recaptured by the recovery wells.
3) Groundwater Section guidelines specify that the infiltration Gallery's "design flow must
not result in saturated conditions within one vertical foot of the excavated bottom of the
gallery". The system cross-section, provided in the application, indicates that the water
table will mound over the infiltration gallery. The system should be designed to prevent
this situation. Please submit information showing the guidelines will be met.
Information requested by the Permits and Engineering Unit
1) Please provide details of the treatment system, i.e. well pumps and curves, sizes of the
settling chamber and finished water chamber, etc.
P.O. Box 29535, Raleigh, North Carolina 27626-0535 Telephone [phone] FAX [phone]

2) The piping schematic shows a possible discharge to the surface waters of the state in
certain circumstances where the infiltration gallery or injection well cannot handle the
flow. This permit application is for a non -discharge permit for groundwater remediation.
This means that under any circumstances no discharge may occur and the facility cannot
have a bypass to the surface waters as an emergency option. This schematic must be
revised to eliminate any possibility for discharge. If a discharge is possible, the system
should be redesigned to prevent any discharge.
3) Please provide a soil scientist's report of the soils or fractured bedrock to establish an
acceptable loading rate. (see application letter g on page 6 of 9). Also Part V.3 and 4 of
the application (page 3 of 9) needs to be completed based on the soil scientist's report.
4) Please complete Part V D and 4 of the application (page 5 of 9) concerning the buffer
requirements being met and if any substances are added to enhance treatment.
5) Please provide calculations showing how must treated groundwater is being intended for
both the injection well and the infiltration galleries. What percentage of the flow will go
to each?
6) Please provide one additional copy of the corrective action plan and site assessment.
Refer to the subject permit application number when providing the requested information. Prior
to submittal of the additional information, please review pages 5 and 6 of 9 of the application to insure all
the needed information is being or has been submitted. Please submit four copies of all
requested information to my attention at the address below except for P&E number 6.
Also, please note that failure to provide this additional information on or before May 6, 1995 will subject
your application to being returned as incomplete, in accordance with 15A NCAC 2H .0208.
If you have any questions regarding the information requested by the Groundwater Section,
please call Brian Wagner at 91gn33-5083 ext. 406. If your questions concern the information requested
by the Permits and Engineering Unit, please call me at 919/ 733-5083 ext. 544.

R.P. Scherer Corporation is requesting a Non -Discharge
Permit for the treatment and re -injection of contaminated
groundwater at the Company's Monroe site in Union County. The
contaminated groundwater resulted from a leaking underground
storage tank containing diesel fuel, and from the use of PCE (for
equipment cleaning) at the facility. The proposed infiltration
gallery will be located on fractured bedrock beneath the soil
horizons at a depth of approximately 20 feet. According to
design procedure, a portion of the treated water will circulate
through the infiltration gallery and the other portion will be
directed to a shallow injection well.
It is recommended that the non -discharge permit be issued
pending review and approval by the Groundwater Section.

Dear Ms. McCaskill:
Enclosed is a Non -Discharge Permit Application with conceptual
design drawings and a $400 application fee for the subject
facility. Also enclosed are two copies of the Phase I Remedial
Investigation Work Plan and Report.
Remediation System Concept
The purpose of the Interim Remediation System is to address
on -site groundwater contamination identified to date and minimize
the potential for off -site contaminant migration. Upon completion
of the Remedial Investigation, the recovery system may be expanded
to expedite the remediation effort.
The proposed Interim Remediation System will consist of
converting four monitoring wells into pumping or recovery wells;
installing an air stripping unit to treat contaminated groundwater;
constructing an infiltration gallery to introduce treated
groundwater upgradient of the recovery wells and area of
contamination; converting an existing monitoring well to a shallow
injection well upgradient of the infiltration gallery and
upgradient of the contaminant plume; and maintaining a background
monitoring well upgradient of the shallow injection well.
The figure found on the following page is a schematic of the
hydraulic concept of the system. When in operation, treated water
in the infiltration gallery and injection well will raise the water
table in that area while the recovery wells will create a
depression in the water table. The resulting hydraulic profile
should further influence groundwater flow toward the recovery
wells. Therefore, the purpose of the infiltration gallery and the
shallow injection well is to expedite the remediation effort.

Page 3 of 5
Since the infiltration gallery and the shallow injection well
are located on or in the bedrock formation, an accurate estimate of
the respective feed rates is not available. It is the intent to
pump as much treated water to the infiltration gallery and
injection well with the excess amount going to a permitted outfall.
This will allow the entire remediation system to operate in an
optimal manner and expedite the remediation effort.
The system design concept and details are presented in
Appendix J of the Phase I Remedial Investigation Report.
NPDES Permit Application
An NPDES Permit Application was submitted to the NCDEHNR on
June 16, 1994. The review has been put on hold pending the outcome
of this application. Based on telephone conversations with Mr.
Sean Goris in the Water Quality Section, the NPDES section would
resume the review of the NPDES Application if the Non -Discharge
option is not permitted or fails to perform adequately.
Final Plans and Specifications
Final Construction Plans and Specifications will be prepared
and submitted upon review and approval of this application. The
final design will include contingencies to accommodate an NPDES
discharge point that will be constructed if and when a discharge is
deemed necessary.
Non -Discharge Permit Submittal
The following comments are in reference to the items found on
pages 5 and 6 of the Non -Discharge Permit Application (Form GWRS
06/94).
Item c. Based on conversations with Mr. Jack Floyd of NCDEM's
Groundwater Section and George Maalouf of Rogers &
Callcott, the information contained in the enclosed NPDES
Application package will serve as the Corrective Action
Plan. This document may be found in Appendix J of the
Phase I Remedial Investigation Report. Also, the Phase
I Remedial Investigation Work Plan and Report will serve
as the Comprehensive Site Assessment. The Phase I
Remedial Investigation Work Plan has previously been
submitted to Mr. John Walch of the Inactive Hazardous
Sites Branch, Superfund Section. A copy of the Work Plan
is enclosed.
Item d. N/A. This is not a permit renewal.

Item f. Well data are found in Appendices E & F of the RI Report.
Item g. A soil scientist report is not applicable. The
infiltration gallery will be located on fractured
bedrock, the injection well is located in the fractured
bedrock. Since the water movement is through fractures,
it was determined that a soil scientist evaluation would
not be beneficial.
Item h. A hydrogeologic description of the site can be found in
Section 1 of the RI Report.
Item i. A description of the remediation system including the
injection process can be found in Section III of the
NPDES Permit Application.
Item j. The proposed monitoring schedule may be found in Section
V of the NPDES Permit Application.
Item k. The injection well will not be pressurized. The water
level in this well will be controlled by water level

probes and an influent water solenoid valve. Should this
system fail, there will be a return line to the treated
water sump for returing any overflow. Inspection of the
injection well will be part of routine maintenance.
Refer to the Conceptual Design Drawings.
Item 1. An analysis of the contaminated groundwater can be found
in Section 4.0 of the RI Report (Table 3).
Item M. Treatment will be provided with a low profile, tray type
air stripper. Vendors have been contacted to verify if
the proposed limits can be met. These limits are
addressed in Section III of the NPDES Application.
Item n. Diagrams of the contaminant plume can be found on Figures
11 through 16 in the RI Report.
Item P. A site visit was conducted by Mr. G.T. Shin of the
Mooresville Regional Office, Water Quality Section on
August 2, 1994. The visit was a follow-up to the NPDES
Permit Application. We understand that a report from the
Regional Office was submitted to Mr. Sean Goris in
Raleigh. In reference to the stream classification, the
unnamed tributary located north of the site has been
classified as a Class C stream as part of the NPDES
review and Waste Load Allocation. A copy is attached.
We appreciate your cooperation on this project. We look
forward to meeting with you after you complete a preliminary review
of this package. We will contact you in approximately two weeks to
set up a meeting to provide you with a project overview and answer
any specific questions. In the meantime, please call us at
[phone] if you have any questions or comments.

A number of halogens and volatiles were found at the site. Using a removal efficicncy of 90% for
these constituents, tetrachloroethene, trichloroethene, and toluene should be Urni.ted to wager quality
standards or EPA criterion. Chloroform should be monitored. A number of metals were found
above or near the water quality standards and should be limited. These include: arsenic, lead and
mercury. BETX parameters appear at the site, but only toluene was in high enough concentrations
to need a limit. A quarterly, chronic WET test will be given as a pass/fail analysis at 90%. Ph and
Oil and Grease will be limited per current policy. The testing results submitted by the applicant
have raised concerns that other halogens may be present and were not adequately repotted in the
data. Because of this -it is recommended that further volatiles and base/neutral - acid extractable
testing be performed on the effluent. It is recommended that volatiles be tested using EPA methods
601 & 602 be done quarterly and that base/neutral - acid extractable testing be performed with 10
significant peaks identified quarterly, with the o2tion given to discontinue testing after 12 months.
Information sent by the facility from samples collected in the plume were the basis for these
dcoi3ion3.

MISCELLANEOUS NFOPUMATION & SPECIAL CONDITIONS
SW—C Instructions or Conditions
Permit must contain flow monitoring requirement such that all volumes of wastewater leaving the
facility are monitored. Recommend continuous flow monitoring. Recommend that volatiles be
tested using EPA methods 601 & 602 be done quarterly and that base/neutral - acid extractable
testing be performed with 10 significant peaks identified quarterly, with the option given to
discontinue testing after 12 months.. This monitoring should coincide with all whole -effluent
toxicity monitoring.
A reopener clause should be placed in the permit to allow for additional limits on these or other
toxicants should the whole -effluent toxicity testing results indicate toxic effects or additional
volatiles/extractables testing indicates other constituents are present.
Explain exact pathway of discharge (i.e. storm sewer to tributary, etc.)
e_wer_to Tributary
Additional Information attached? (Y or N) If yes, explain with attachments.

CHRONIC TOXICITY PASS/FAIL ?ERMIT Ll:�I1T (QRTRL Y)
The effluent thscharge shall at tit, time exhibit chronic toxicity u-sung test procedures Outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (.North Carolina Chronic Bioassay
Procedure - Revised *September 1989) or subseiluent versiOWS.
The effluent concentration at which there may be no observable inhibition of itiproduction or i` niticant mortality
is 1° % (defined as treatment two in the Nlonh Carolina procedure document). I ie permit holder shall perform
quarterquartert monitoring using this procedure to establish compliance with the permit condition. The first test will be
performed after thirn dais frota the effective date of this permit during the months of
NOV. FFa. nfau .���. Effluent sampling for this testing shall be performed at the NPDFS
permitted final e'luert discharge below all treatment p-ocesses.
All toxicity testing results required as part of this peani.t condition will be entered on the Eftlucnt Discharge
Monitoring Form (MR-1) for the inondi in which it was performed. using the parameter code TGP3B.
Additionally, DF.,M Foam AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, V.C. 27601
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in
,ssociation with the toxicity tests, as well as all dose/response data. Total residual. chlorine of the effluent toxicity
.ample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to ineet specified limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing. this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Environmental Management indicate potential impacts to the receiving stream. this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival and appropriate environmental controls. shall constitute an invalid test and will require immediate
retesting(wi.thin 30 days of initial monitoring event). Failure to submit suitable test results will constitute
noncompliance with monitoring requirements.
