1.0 INTRODUCTION
This twenty-fifth progress report summarizes the activities and results for 2019 annual Site -wide groundwater
monitoring. These activities occurred at the former Flakt Products, Inc. site (the Site), located at 2000 Lowery
Street in Winston-Salem, North Carolina, pursuant to an Administrative Order of Consent (Flakt Products,
1997). The Site is registered as North Carolina Department of Environment Quality (NCDEQ) Site No.
NONCD 000 0017, and it is shown in Figure 1 (all figures are in Appendix A). Remedial goals and activities
for the Site are governed by the Inactive Hazardous Sites Response Act and the North Carolina Registered
Environmental Consultant (REC) Program implementation rules found in Title 15A of the North Carolina
Administrative Code, Subchapter 2L (NCAC 2L) (NCDEQ, 2015). Groundwater quality standards are listed
in Subchapter 15A NCAC 2L .0202.
A Groundwater Recovery Hydraulic Control System (System) was operational at the Site from June 1998
until July 2017. During operation, the System extracted, treated and discharged groundwater to Brushy
Fork Creek in accordance with the National Pollutant Discharge Elimination System (NPDES), Permit No.
NC0085871 (NCDWR, 2017). The System was shut down on July 27, 2017 and has remained off as an
initial step toward assessment of a potential conditional closure at the Site based on plume stability.
The November 2019 sampling event represents the third round of sampling data collected since the System
was shut down on July 27, 2017. The results from the groundwater monitoring event conducted in 2019
continue to demonstrate the remedial effectiveness in reducing contaminants of concern (COCs) and in
enhancing the stability of the plume to reduce off -site migration. Based on the demonstrated stability of
the groundwater plume in more than 30 years of groundwater monitoring Wood will initiate discussions
with NCDEQ about pursuing a conditional closure at the Site.

2.0 SCOPE OF WORK
2.1 ANNUAL SITE -WIDE GROUNDWATER MONITORING EVENT
Wood Environment & Infrastructure Solutions, Inc. (Wood) personnel performed the annual Site -wide
groundwater monitoring event in November 2019 to provide a comprehensive set of groundwater analytical
data for this twenty-fifth progress report. Groundwater samples were collected from 16 monitoring wells
during the event. Complete results for all wells sampled in November 2019 are included in the laboratory
report in Appendix B.
The annual scope of work included the collection and analysis of groundwater samples from 16 monitoring
wells, including two off -site monitoring wells, and analysis of four quality control samples (Table 2-1). All
20 samples were submitted to TestAmerica, Inc., for analysis of a reduced volatile organic compound
(VOC) list by Environmental Protection Agency (EPA) Method 8260D. The reduced VOC list includes
the primary COCs at the Site: tetrachloroethene (PCE); trichloroethene (TCE); 1,1-dichloroethene (1,1-
DCE); cis-1,2-dichloroethene (cis-1,2-DCE); trans-1,2-dichloroethene (trans-1,2-DCE); vinyl chloride;
1,1,1-trichloroethane (1,1,1-TCA); 1,1-dichloroethane (1,1-DCA); and 1,2-dichloroethane (1,2-DCA). In
addition, 11 of the samples were analyzed for 1,4-dioxane by EPA Method 8260B with select ion
monitoring (SIM).

2.2 TREATMENT SYSTEM
Wood shut the System down on July 27, 2017 as an initial step toward assessment of a potential conditional
closure at the Site based on plume stability, and subsequently submitted a July 31, 2017 letter to the NCDEQ
requesting to cease monitoring associated with the NPDES permit (Amec Foster Wheeler, 2017). The
NCDEQ responded with an August 4, 2017 letter indicating their agreement to waive the requirement to
submit monthly Discharge Monitoring Reports during the period of no discharges (NCDEQ, 2017). Based
on the recent annual monitoring results, the System will remain off for 2020.

3.0 SUMMARY OF RESULTS
3.1 ANNUAL SITE -WIDE GROUNDWATER MONITORING EVENT
The monitoring wells sampled during the annual Site -wide monitoring event are divided into three main
categories: (1) Former South Pit Area, (2) Former UST Area and (3) off -site monitoring wells. These
categories include two former sources of contamination (Former South Pit and Former UST Area) identified
during facility investigations in 1988 and 1989 (Weston, 1991) as well as off -site downgradient wells. The
data gathered during the Groundwater Remedial Investigation indicated that the Former South Pit Area and
the former UST area (located within a former catalyzed hydrogen peroxide [CHP] treatment area) appeared
to have contributed to the presence of VOCs in the groundwater. The VOCs in the groundwater near the
Former South Pit Area could not be clearly distinguished from VOCs that originated in the Former North
Pit Area (Rust Environment and Infrastructure, 1995).
A summary of monitoring wells sampled and the analyses performed are presented in Table 2-1 (see
Section 2). The monitoring well sample results for the 2018 and 2019 monitoring events are summarized
in Table 3-1.

A comprehensive table showing historical groundwater monitoring results since June 1998 is provided in
Appendix C (Table C-1). June 1998 is when the groundwater recovery system began operation and is,
therefore, considered a "Baseline" event for remediation of Site -wide groundwater. The sample result tables
present only positive (i.e., detected) CVOC results for the primary COCs, which are 1,1,1-TCA; TCE; and
their predominant daughter products: 1,1-DCA, 1,2-DCA and 1,1-DCE, respectively. Table 3-1 also
presents the results for 1,4-dioxane, which was added to the sampling program in December 2005 at the
request of the NCDEQ. Figure 2 (Appendix A) depicts 2018 and 2019 Site -wide sample results for the
primary COCs and related daughter products in the monitoring wells, as compared to the applicable NCAC
2L limit. Comprehensive results can be found in the laboratory reports located in Appendix B.
We note that since 2016 the site water table has been at or near historic high levels. This condition is
attributable to the shutdown of the System in 2017, higher than normal rainfall in recent years, and

modifications made by the current Site owner to the Site storm water management system at the southern
end of the facility as part of Site redevelopment activities. Certain contaminant concentrations in certain
monitoring wells have fluctuated the past few years, and some of those fluctuations may be attributed to
the high Site water table which resulted in diffusion of contaminant mass near these wells. However, the
total contaminant mass of the shallow wells most likely to be affected by a high water table (MW-110,
MW-112, MW-130, MW-132S, MW-133S, and MW-134S) recently decreased from 1,671 µmole/L in
2017 to 751 µmole/L in 2018 and remained consistent at 753 µmole/L in 2019, indicating that the effects
from any diffusion of mass as a result of the high water table have stabilized. It is also notable that, as
detailed below, the current contaminant concentrations remain lower than historical Site concentrations
which resulted in no impacts related to Site vapor intrusion or groundwater at the furthest downgradient
off -site monitoring wells. The continued lack of COC detections in the off -site wells indicates that the
remaining contaminant plume is stable.
3.1.1 FORMER SOUTH PIT AREA
Monitoring well MW-106 is located immediately downgradient of the Former South Pit Area. COC
concentrations in MW-106 in November 2019 were comparable to 2018 results, with only a low-level of TCE
reported above the NCAC 2L standards. With the high water table, this demonstrates a lack of residual mass
in the smear zone near the Former South Pit Area.
Monitoring wells MW-107 and MW-130 are located southeast of the Former North Pit and South Pit Areas.
Due to the downgradient location of these monitoring wells, it has been difficult to determine whether past
CVOC detections in these wells were the result of the Former North Pit Area source or the Former South Pit
Area source. The current analytical results of COCs for MW-107 and MW-130 were generally comparable to
the October 2018 results with slight increases in TCE and 1,1-DCE.
3.1.2 FORMER UNDERGROUND STORAGE TANK AREA
Monitoring wells MW-112, MW-129 and MW-132 through MW-135 are located in the vicinity of a former
20,000-gallon UST, which was removed in 1998. This area underwent in -situ chemical oxidation injections
of CHP between 2012 and 2015.
In November 2019, the 1,4-dioxane concentration in shallow monitoring well MW-112 decreased from the
October 2018 sampling event and has the second lowest historical concentration dating to 2005.
3-3
Final 2019 Annual Progress Report for WSalem
1/28/2020 3:49 PM

Concentrations of primary CVOCs in MW-112 were mostly higher than 2018 but remain significantly
lower than historical concentrations. With the high water table, these results indicate a lack of significant
residual mass in the smear zone. In monitoring well MW-129, most primary CVOCs decreased moderately
from October 2018 and remain significantly lower than historical concentrations.
MW-132S and MW-132D had moderate decreases in all primary COCs in November 2019. The VOC
mass at shallow monitoring well MW-132S has decreased for four consecutive events and is at a historical
low. With the high water table, this demonstrates a lack of residual mass in the smear zone. All VOC
concentrations in MW-132D decreased moderately from 2018 while 1,4-dioxane was generally consistent
with detections in the past few years. In shallow monitoring well MW-133S certain primary CVOC
concentrations increased moderately from October 2018, e.g., 1,1-DCA, 1,2-DCA and 1,4-dioxane, while
TCE decreased significantly. Current contaminant concentrations remain well below historical high
concentrations in other nearby wells. Most CVOC concentrations decreased significantly in MW-133D
while 1,4-dioxane increased somewhat.
In shallow monitoring well MW-134S, primary COC concentrations are generally comparable to the
October 2018 results. The CVOC concentrations in MW-134D increased slightly in November 2019 while
the 1,4-dioxane concentration increased to a historic high. The increase in 1,4-dioxane in deeper well MW-
134D is likely associated with the increase in 1,4-dioxane in co -located shallow well MW-134S in 2017
(102,000 µg/L). It's notable that after 2017 1,4-dioxane in MW-134S decreased significantly to 42,400
µg/L in 2018 and remained consistent in 2019 at 43,700 µg/L. Thus it appears that the effects of the high
water table on contaminant mass have stabilized at MW-134S, which should subsequently facilitate
stabilization of the mass in MW-134D. The current 1,4-dioxane results in MW-134S/D are significantly
lower than the historic high concentrations near this area (218,000 µg/L in 2007) which did not result in
any detections in the off -site wells.
In monitoring well MW-135, primary CVOCs concentrations fluctuated overall while 1,4-dioxane
concentrations increased slightly in November 2019. While TCA and 1,1-DCE are at or near historical
high concentrations, the current concentrations are significantly lower than historical Site -wide
concentrations with no documented impacts to the furthest downgradient off -site wells.
Monitoring wells MW-E and MW-110 are located east of the former UST area. In November 2019, no COCs
were detected above their respective NCAC 2L Standards in monitoring well MW-E. In MW-110, the
primary CVOCs remained generally comparable to concentrations from October 2018.

The individual CVOC results are shown on Figure 2 (Appendix A) and in Table 3-1.
3.1.3 OFF -SITE MONITORING WELLS
Two off -site monitoring wells, MW-124 and MW-125, are included in the Site -wide monitoring program.
During the 2019 annual monitoring event, no COC constituents were detected in either of these wells for
the tenth consecutive year. 1,4-dioxane has never been detected in any of the off -site monitoring wells.
The two furthest down -gradient off -Site wells, MW-123 and MW-126, never had any detections of COCs
above any NCAC 2L limit and were removed from the monitoring program following sampling in 2013.
It's notable that even prior to active remediation MW-123 and MW-126 had no CVOC detections,
indicating the existence of a degree of stable plume conditions prior to remediation. The lack of COC
detections in the off -site monitoring wells for the past ten years coupled with the historical lack of any
NCAC 2L limit exceedances in MW-123 and MW-126 indicates that the remaining Site contaminant plume
is stable.
3.2 POTENTIOMETRIC SURFACE
Site -wide groundwater elevations obtained during November 2019 (from 20 monitoring wells and 7
piezometers located adjacent to the recovery wells) were used to develop the potentiometric surface map
which depicts groundwater elevations for the shallow and deeper groundwater units. AutoCAD Civil 3D
2018 was used to plot the potentiometric surface map in Figure 3 (Appendix A). These programs
mathematically calculate contours based upon groundwater elevation measurements collected in the field.
Certain areas of the Site groundwater were elevated in 2019 compared to historical levels, particularly near
MW-106 and near the former UST Area. As previously mentioned, the higher water table is attributable to
the shutdown of the System in 2017, higher than normal rainfall in recent years, and modifications made
by the current Site owner to the Site storm water management system at the southern end of the facility as
part of Site redevelopment activities. The November 2019 potentiometric surface map indicates that the
Site groundwater gradient is generally southward, consistent with historical monitoring events; however,
groundwater analytical data from previous investigations indicate that COC migration appears to have been
southwesterly, approximating the trace of historic drainage features (Rust Environment and Infrastructure,
1995). The potentiometric surface and the lack of COCs in the off -site wells are an indicator that the
remaining Site contaminant plume is stable.

3.3 INVESTIGATION -DERIVED WASTE
Investigation -Derived Waste (IDW) consisted of groundwater sampling purge water, equipment
decontamination water, disposable personal protective equipment (PPE), and other miscellaneous refuse.
Used PPE and other miscellaneous refuse was placed in plastic bags and discarded into an off -site sanitary
trash container for disposal at a sanitary landfill. Liquid IDW was containerized in a Department of
Transportation -approved 55-gallon steel drum and was profiled based on analytical data and generator
knowledge. The drum of liquid IDW was transported from the Site by Clean Harbors Environmental
Services, Inc., on November 26, 2019 for disposal at their facility in La Porte, Texas. The hazardous waste
manifest for the drum of liquid IDW is provided in Appendix F.

4.0 ANALYTICAL PROGRAM
Overall data quality is assessed by grouping particular data evaluation findings and reviewing them in terms
of overall precision, accuracy, representativeness, completeness, and comparability (PARCC) criteria.
Groundwater data generated during this monitoring period were evaluated for PARCC criteria after receipt
of all analytical data.
4.1 PRECISION
Precision is a quantitative evaluation of the repeatability of a measurement. Precision of analytical
measurements is determined by calculating the relative percent difference (RPD) between the numerical
values. Comparison of results from a duplicate of a field sample may indicate an overall precision of a data
set. However, field duplicates may be influenced by sampling precision and are not controlled as laboratory
duplicates.
For quality control purposes, a field duplicate was collected for each set of 20 field samples, resulting in one
duplicate sample for the November 2019 annual groundwater monitoring event. Field duplicate precision
is presented in the following table.

The RPDs were below the National Functional Data Validation Guideline of 30 for duplicate water samples
analyzed as part of the November 2019 monitoring event. Based on the RPD values from the annual event,
overall field duplicate precision is acceptable.

4.2 ACCURACY
Accuracy is a quantitative measurement of agreement between an analytical result and the true value.
Accuracy is determined by comparing known amounts of analytes, which are added to the sample prior to
analysis, to the field analytical results. Accuracy is expressed as a percentage of recovery of the total spiked
analyte. For VOC analyses, each sample was spiked with surrogate compounds prior to analysis (and
extraction). Surrogate recoveries evaluate accuracy and identify interferences from the sample matrix.
Surrogate recoveries for MW-129 and MW-135 were outside control limits due to the presence of matric
interference, and therefore the samples were re -analyzed and reported at a dilution. Remaining surrogate
recoveries were acceptable for VOC analyses for the monitoring event.
4.3 REPRESENTATIVENESS
Representativeness is a qualitative measurement of the degree to which analytical results reflect the true
concentrations of analytes that may (or not) be present in a sample. Representativeness of organic analytical
results of true site conditions is evaluated using trip blanks, field blanks, and rinse blanks from
decontaminated sampling equipment. Target organic compounds in quality control samples may represent
contamination during sampling or transportation of samples to the laboratory. Compliance with holding
time and extraction criteria also assures representativeness of results.
The November 2019 groundwater monitoring event included analysis of one field blank, one trip blank,
and one rinse blank. Distilled water was used for the field blank and rinse field equipment. No COC
analytes were detected in the field blank, trip blank, or rinse blank.
Representativeness is considered complete.
4.4 COMPLETENESS
Completeness is a quantitative measurement of the usability of a data set. Completeness is defined as the
percentage of data that satisfy validation criteria. Rejected data are not usable. Data qualified as estimated,
however, is usable. Completeness goals were 100 percent for this report and were met for the November
2019 monitoring event.

4.5 COMPARABILITY
Comparability is a qualitative assessment of the confidence with which different data sets may be used to
characterize a site. Comparability is a necessary criterion because sampling is often performed at different
times and precision, accuracy, and representativeness are unique to each monitoring event. Comparability
between data generated at different times at a single site is evaluated by reviewing sample collection and
handling procedures, sample matrix, and analytical methods used. Standardization of sampling protocols
and analytical methods assures comparability as long as precision and accuracy criteria are satisfied for
each data set. The overall analytical performance for this report was evaluated and should be comparable
to previous and future data sets.

5.0 CONCLUSIONS AND RECOMMENDATIONS
During the November 2019 annual Site -wide monitoring event, no COCs were detected in the two off -site
wells (MW-124 and MW-125) for the tenth consecutive year. 1,4-dioxane has never been detected in any
of the off -site monitoring wells. It's notable that even prior to remediation the two furthest downgradient
off -site monitoring wells (MW-123 and MW-126) had no CVOC detection, thus indicating the existence
of a degree of stable plume conditions prior to remediation. These notable results, coupled with the
historical lack of any NCAC 2L limit exceedances in MW-123 and MW-126, indicate that the remaining
contaminant mass is stable.
A higher than normal water table the past few years has resulted in recent fluctuation of certain contaminant
concentrations in certain monitoring wells. However, the total contaminant mass of the shallow wells most
likely to be affected by a high water table (MW-110, MW-112, MW-130, MW-132S, MW-133S, and MW-
134S) recently decreased from 1,671 µmole/L in 2017 to 751 µmole/L in 2018 and remained consistent at
753 µmole/L in 2019, indicating that the effects of any diffusion of mass as a result of the high water table
have stabilized. It is also notable that the current contaminant concentrations remain lower than historical
Site concentrations which resulted in no impacts related to Site vapor intrusion or groundwater at the
furthest downgradient off -site monitoring wells.
The stability of the groundwater contaminant plume will continue to be evaluated in consideration of the
North Carolina General Assembly Session Law 2015-286, which allows risk -based remediation as a
cleanup option at contaminated sites where the use of remedial actions and land -use controls can reliably
ensure that affected properties are safe for their intended uses. As an initial step toward assessment of a
potential conditional closure at the Site based on plume stability, Wood shut the System down on July 27,
2017 and it has remained off since that time.
Based on the demonstrated stability of the groundwater plume in more than 30 years of groundwater
monitoring, Wood will initiate discussions with NCDEQ about pursuing a conditional closure at the Site.
Pending the results of the conditional closure discussion with NCDEQ, the groundwater contaminant plume
will continue to be tracked through future annual monitoring events.

Receipt
The samples were received on 11/9/2019 9:30 AM; the samples arrived in good condition, properly preserved and, where required, on ice.
The temperature of the cooler at receipt was 1.1° C.
GC/MS VOA
Methods 8260C, 8260D: The continuing calibration verification (CCV) analyzed in batch 180-298709 was outside the method criteria for
the following analyte(s): Bromomethane and Chloroethane. (HIGH). As indicated in the reference method, sample analysis may proceed;
however, any detection for the affected analyte(s) is considered estimated.
Methods 8260C, 8260D: Surrogate recovery for the following samples were outside control limits: MW-135 (180-98536-16) and MW-129
(180-98536-17). Evidence of matrix interference is present; re -analysis at a dilution will be performed.
Method 8260D: Internal standard (ISTD) response for TBA-d9 for the following sample was outside acceptance criteria: MW-135
(180-98536-16). This ISTD does not correspond to any of the requested target compounds; therefore, the data have been reported.
Methods 8260C, 8260D: The continuing calibration verification (CCV) analyzed in batch 180-298790 was outside the method criteria for
the following analyte(s): 1,2,3-Trichlorobenzene, 1,2,4-Trichlorobenzene, 2-Hexanone and Vinyl chloride. (LOW) A CCV standard at or
below the reporting limit (RL) was analyzed with the affected samples and found to be acceptable. As indicated in the reference method,
sample analysis may proceed; however, any detection for the affected analyte(s) is considered estimated.
Methods 8260C, 8260D: The continuing calibration verification (CCV) analyzed in batch 180-298790 was outside the method criteria for
the following analyte(s): Bromomethane, Chloroethane and Trichlorofluoromethane. (HIGH). As indicated in the reference method,
sample analysis may proceed; however, any detection for the affected analyte(s) is considered estimated.
Methods 8260C, 8260D: The continuing calibration verification (CCV) analyzed in batch 180-298790 was outside the method criteria for
the following analyte(s): Methyl acetate & 1,4 Dioxane. (LOW MINIMUM RRF). A low-level LCS (LLCS), spiked at the reporting limit (RL),
was prepared with this batch. The affected target analytes recovered within acceptance limits; therefore, the LLCS demonstrates the
analytical system had sufficient sensitivity to detect the compounds. As indicated in the reference method, sample analysis may proceed;
however, any detection for the affected analyte(s) is considered estimated.
Method 8260D: The continuing calibration verification (CCV) analyzed in batch 180-298931 was outside the method criteria for the
following analyte(s): 1,1,1-Trichloroethane and Chloroethane. (HIGH). As indicated in the reference method, sample analysis may
proceed; however, any detection for the affected analyte(s) is considered estimated.
Methods 8260C, 8260D: The following samples were diluted to bring the concentration of target analytes within the calibration range:
MW-112 (180-98536-11), MW-132S (180-98536-12), MW-132D (180-98536-13), MW-134S (180-98536-14), MW-134D (180-98536-15),
MW-135 (180-98536-16) and MW-129 (180-98536-17). Elevated reporting limits (RLs) are provided.
Method 8260D: Internal standard (ISTD) response for TBA-d9 for the following sample was outside acceptance criteria: MW-134S
(180-98536-14). This ISTD does not correspond to any of the requested target compounds; therefore, the data have been reported.
Method 8260B SIM: The following samples were diluted to bring the concentration of target analytes within the calibration range: MW-133S
(180-98536-9), MW-133D (180-98536-10), MW-112 (180-98536-11), MW-132S (180-98536-12), MW-132D (180-98536-13), MW-134S
(180-98536-14), MW-134D (180-98536-15), MW-135 (180-98536-16) and MW-129 (180-98536-17). Elevated reporting limits (RLs) are
provided.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

HAZARDOUS WASTE CODES LISTED BELOW ARE RESTRICTED WASTES WHICH ARE PROHIBITED FROM LAND DISPOSAL
WITHOUT FURTHER TREATMENT UNDER THE LAND DISPOSAL RESTRICTIONS, 40 CFR PART 268.7 (a)(2), AND RCRA SECTION
3004(D), IN ACCORDANCE WITH 40 CFR 268.7(a), THE EPA WASTE CODE, WASTE SUBCATEGORY, AND TREATABILITY
GROUPS, AS APPLICABLE, ARE INCLUDED BELOW.
INSTRUCTIONS — COMPLETE ALL SECTIONS, REFER TO PAGE 3 OF THIS FORM FOR KEY TERMS/DEFINITIONS.
Column 1 - Line Item: Enter the manifest line item number (e.g., 11a) that corresponds to the waste code(s).
Column 2 - Waste Codes/Subcategory: Check off all applicable waste codes. For D001 through D043, also check applicable
subcategory; for F001 through F005, check applicable constituents.
Column 3 - Wastewater/Non-wastewater. Check off "WW" for wastewater and "Non-WW" for non -wastewaters.
Column 4 - LDR Handling Code: Circle the appropriate handling code, as follows:
1 = The waste is a characteristic hazardous waste D001, D002, D003, D004-D011, or D018-43 which is intended for
treatment/disposal in a CWA system, CWA-equivalent system, or Class I SDWA system. Underlying Hazardous Constituents
(UHC's) are NOT required to be identified.
1A = The waste is a characteristic hazardous waste D001 High TOC Ignitable Liquids Subcategory (Le., greater than
or equal to 10% TOC). Pursuant to 40 CFR 268.40, the waste must be treated using organic recovery (RORGS) or combustion
(CMBST) technology. UHC's are NOT required to be identified.
2 = The waste is a characteristic hazardous waste D001 (other than High TOC Ignitable Liquids), D002, D003 Explosive, Water
Reactive or Other Reactive subcategory, D004-D011, D012-17 non -wastewater, or D018-43 which is intended for
treatment/disposal in a non-CWA system, non-CWA-equivalent system, or non -Class 1 SDWA system located in the United States.
All UHC's which are reasonably expected to be present must be identified, except for D001 waste that is intended to be treated
using organic recovery (RORGS) or combustion (CMBST) technologies. Identify UHC's by completing Sections I and IV of CHI
Form LDR-1 Addendum and attach completed Addendum to this form. •
3 = The waste is a characteristic (Le., D-code) or listed (i.e., F-, K-, U-, or P-code) hazardous waste which is intended for export and
treatment/disposal at a facility located outside the United States. LDR treatment standards do not apply to hazardous waste
treated/disposed in a foreign country, and per USEPA guidance, the identification of UHC's (if applicable) is not required for
hazardous waste that is intended to be exported, Note however that if the exported waste is subsequently retumed for
treatment/disposal in the United States, all applicable LDR regulations would apply and a revised LDR notification would be
required.
4 = The waste meets the definition of hazardous debris pursuant to 40 CFR 268.2(h) and is intended for treatment/ disposal in
compliance with the altemate debris treatment technologies of 40 CFR 268.45. In accordance with the requirements of 40 CFR

KEY TERMS/DEFINITIONS
CLASS 1 SDWA SYSTEM means a Class I deep well facility regulated under the Safe Drinking Water Act (SDWA).
CWA SYSTEM means a centralized wastewater treatment facility discharging under a Clean Water Act (CWA) permit. For example, a CWA
facility would treat organic or inorganic aqueous wastes and discharge the treated effluent to the local sewer system. FYamples of CWA
treatment systems owned and operated by Clean Harbors include the wastewater treatment operations at Baltimore (including the CES
system), Bristol, Chicago, Cincinnati and Cleveland.
CWA-EQUIVALENT SYSTEM means a "zero discharge system" that engages in "CWA-equivalent" treatment before land disposal. Zero -
discharge facilities treat hazardous wastes using"CWA-equivalent" treatment methods, but do not discharge the treatment effluent to a
sewer or water body (e.g., spray irrigation land farm). "CWA-equivalent" treatment methods means biological treatment for organics, alkaline
chlorination, or ferrous sulfate precipitation for cyanide, precipitation/ sedimentation for metals, reduction of hexavalent chromium, or other
treatment technology that can be demonstrated to perform equally or greater than these technologies.
HIGH TOC IGNITABLE LIQUIDS SUBCATEGORY means an ignitable liquid hazardous waste (waste code D001) which contains
greater than or equal to 10% total organic carbon (TOC). Pursuant to 40 CFR 268.40, such wastes must be treated using organic recovery
(RORGS) or combustion (CMBST) technology. Examples of RORGS technologies include the CES unit at Clean Harbors of Baltimore.
Examples of CMBST technologies include hazardous waste fuel blending and subsequent reuse at a cement kiln, or destruction at a RCRA
incinerator.
WASTEWATERS are wastes that contain less than 1% by weight total organic carbon (TOC) and less than 1% by weight total suspended
solids (TSS). [See 40 CFR 268.2(f)]
