Enclosure 2: All Required Text Attachments (A through H)

Attachment A
Site Description and Incident Information
Some of the information requested in this attachment is presented in the RCRA Facility Investigation
(RFI) Report (CDM Smith, July 2013), which is included in the enclosed electronic disk. The proposed
site remediation plan is described in the Enhanced Bioremediation Interim Measure (IM) Work Plan
(IESI, 2018) which is also on the enclosed electronic disk. The electronic disk also contains two
monitoring reports (2013b and 2018a) as well as pertinent additional tables, figures, logs and reference
papers. Additional details are provided below regarding where to find specific information in the various
referenced reports:
1. Contaminant(s) of concern
The contaminants of concern are volatile organic compounds(VOCs), and specifically chlorinated ethene
and ethane VOCs. Soil and groundwater VOC concentration results from multiple investigations are
presented in Section 4 of the RFI Report, and Section 5.3 of the RFI Report contains conclusions
regarding the extent of VOCs in groundwater.The attached 2017 monitoring report(Table 4 and Table 5)
contains recent site-wide groundwater analytical data.
2. Source(s) and date(s) of the contaminant release
Section 1.1 of the RFI Report provides a site history, and Section 1.2 describes each identified waste
management unit (WMU). As described in the report, the majority of the VOCs in groundwater are
believed to have originated from WMU-B (Underground Storage Tank)based on the investigation results
and site history. The proposed work is part of an interim measures plan (plan) that proposes enhanced
anaerobic dechlorination (EAD) and downgradient aerobic co-metabolic degradation to address VOC
impacted groundwater at the main source area(former WMU-B).
3. Remedial actions to date
See Sections 1.3 and 6 of the RFI Report. In addition, a pump and treat system has been installed at the
site and has an existing UIC permit (to which this is a modification). Lastly, the former WMU-B waste
area was treated by thermal remediation between 2015 and 2017. The proposed EAD remediation (IM)
will treat residual VOC contamination that remains post thermal treatment as described in the Plan.
4. Current land use
The site is currently owned and operated by Moog Inc. (Moog). Moog designs and manufactures brush
and brushless DC motors, synchros, resolvers, solenoids, and air moving solutions for both commercial
and military markets at this facility.Details regarding surrounding land use are provided in Section 2.1 of
the RFI Report.

5. Potential receptors
Current potential receptors include construction workers, outdoor workers, indoor workers, and off site
residents. A portion of the residents living near the site previously used private wells to meet domestic
water supply needs. These residential properties are currently connected to the Town of Murphy water
supply, and private wells located on these properties have been locked out from use per executed
agreements with .the property owners. The results from a risk assessment submitted to the U.S.
Environmental Protection Agency (EPA) and North Carolina Department of Health and Environmental
Control (NCDENR) calculated that all risks to current receptors are within the range of risks that EPA
considers acceptable.
6. Incident number and name of oversight agency
EPA Region 4 is the lead regulatory agency on this project with support provided by the North Carolina
Department of Environmental Quality(NCDEQ). The EPA ID number for this site is NCD 044 438 406.

Attachment B
Soils Evaluation
Reinjection of treated groundwater is not planned above the seasonal high water level or within seven feet
of land surface.As such, soil evaluation is not applicable.Details regarding the site geology are presented
in Section 5.1 of the RFI Report.

Attachment C
Hydrogeologic Evaluation
The information requested in this attachment is primarily presented in the RFI Report(CDM Smith,
July 2013a),which is included on the enclosed disk.Additional details are provided here along with
where to find specific information in the RFI Report:
1. A description of the regional and local geology and hydrogeology
Regional geology and hydrogeology are discussed in Sections 2.3 and 2.4, respectively, of the RFI Report.
Summaries of the local geology and hydrogeology are presented in Sections 5.1 and 5.2, respectively, of the
RFI Report.
2.A description,based on field observations of the site, of the site topographic setting,
streams,springs and other groundwater discharge features, drainage features, existing and
abandoned wells,rock outcrops, and other features that may affect the movement of the
contaminant plume and treated wastewater
Section 2.2 of the RFI Report includes information on topography and drainage. Detailed descriptions of
groundwater movement and VOC migration in groundwater are presented in Sections 5.2(Hydrogeology)
and 5.6(Conceptual Hydrogeologic Model) of the RFI Report.
3 Changes in lithology underlying the site
Sections 5.1 (Geology) and 5.2 (Hydrogeology) of the RFI Report discuss changes in lithology on site
and off site. Figures 5-1 through 5-4 provide surface elevation maps for the transition zone and bedrock
zone as well as a map of transition zone thickness. Figures 4-19 through 4-21 show geologic cross-
sections for the WMU-B area.
4. Depth to bedrock and occurrence of any rock outcrops
See response to Item#3.
5. The hydraulic conductivity,transmissivity, and storativity(specific yield if unconfined
aquifer) of the affected aquifer(s)
Estimated values for hydraulic conductivity(k),transmissivity(T),and storativity/specific
yield(S/Sy)in the proposed area of are as follows:
it
Layer K(ft/day);T(ft2/day); S/Sy(dimensionless)
Fine-Grained Alluvium K=0.014;T= —0.4; S/Sy=0.15
Coarse-Grained Alluvium K=30;T=-500; S/Sy=0.15

,
Residuum K=5;T=-150;S/Sy=0.15
Transition Zone K= 10;T=-2,750; S/Sy=0.005
Bedrock(1)K=0.005;T=-1 ; S/Sy=5 x 10-7
(1)-The bedrock transmissivity is highly variable because of location-specific fractures.
6. Depth to the seasonal high water table
Figures 3 and 4 of the April 2013 semi-annual groundwater monitoring report (April 2013 event), which
is provided on the enclosed disk, show potentiometric surface maps for the regolith transition zone and
bedrock zone. This report also includes tabulated measurements for the depths to groundwater.
Considering the unusually high amount of precipitation in 2013, these maps are expected to represent
high water table conditions.
7. A discussion of the relationship between the affected aquifers of the site to local and
regional geologic and hydrogeologic features
Similar to the above items,this is covered by Sections 2.2(Topography and Drainage),2.3 (Regional
Geology),2.4(Hydrogeology),5.1 (Geology),and 5.2(Hydrogeology)of the RFI Report.
8.A discussion of the groundwater flow regime of the site focusing on the relationship of
the plume and remediation system to groundwater receptors,groundwater discharge
features, and groundwater flow media
See Section 5.6(Conceptual Hydrogeologic Model)of the RFI Report.

Attachment D
Demonstration of Hydraulic Control
The area where the proposed injections will take place lies within the capture zone of the existing pump
and treat system and, as such, no additive migration is expected to occur(see Figures 2-2 and 3-2 of the
IM Work Plan for injection area locations).

Maps and Cross-Sections
The information requested in this attachment is primarily presented in the RFI Report(CDM Smith,
July 2013a),which is included on the enclosed electronic disk.Additional details are provided here along
with where to find specific information in the RFI Report:
1.A scaled map of the site,with site-specific topographic contour intervals and showing all
facility-related structures and fences within the treatment, storage and disposal areas
See Figure 1-7 of the RFI Report.
2. Locations of all test auger borings or inspection pits
See Figures 1-3 through 1-9 of the RFI Report.Figures 2-2 and 3-2 of the IM Work Plan show the location of
the proposed injection points. The great majority(116)of the injection locations are existing thermal heating
probes. Several(6)new injection wells are planned.
3.The location of all wells (including usage and construction details if available),designated
wellhead protection areas, streams (ephemeral, intermittent, and perennial), springs,lakes,
ponds, other surface drainage features, and any other site activities or features that may
involve possible exposure to contamination within 500 feet of all waste treatment, storage,
and disposal sites
On site and off site wells are shown on Figures 1-2, 1-3, 1-7, 1-8, 1-9, and 4-2 of the RFI Report. Well
construction details for all RFI installed wells are provided in Table 3-1 of the RFI report. Well construction
information for proposed injection locations is shown in Table 1 and Figure 4-2 of the IM Plan.
4 Setbacks specified in 15A NCAC 02T .1606
All proposed injection locations meet the required setbacks.
5.Delineation of property boundaries,review boundaries, and compliance boundaries
The review boundary is proposed to be synonymous with the waste boundary with monitoring based on
testing of groundwater quality within the zone of remediation(Section G of this permit).
6. The horizontal and vertical extent of the contaminant plume for each of the
contaminants of concern,including isoconcentration lines and plume cross-sections
Figures 5-7 and 5-8 of the RFI Report present isoconcentration maps for VOCs in the regolith/transition
zone and bedrock zone, respectively. Additional concentration maps for the source area (WMU-B) are
presented in Figures 4-26 through 4-31. Cross-sections through the source area with groundwater
concentrations shown are presented in Figures 4-19 through 4-21. Figure E-3 provides a geologic cross-

'
section location map with corresponding cross sections provided on Figures E-4 and E-5. Please note that
these figures are pre-thermal remediation. Significant groundwater quality improvement has been
achieved by the thermal remediation system (removed about 7,000 lbs. of VOCs). For example, total
VOCs have been reduced from approximately 25 mg/L in well PMW-10 (4/2015) to approximately 2.5
mg/L in 10/2017. Similarly at well PMW-9D total VOCs have been reduced from approximately 36
mg/L in 4/2015 to approximately 6 mg/L in 10/2017. For all of the shallower wells,total VOC reductions
are more pronounced and generally exceed 95%reduction. In summary, thermal treatment resulted in an
overall VOC reduction in the range of 90-95% at most/all locations. The most recent analytical sampling
data report is included as an attachment(CDM-Smith,2018b).
7. Cross-sections depicting soil and rock layers and features to a depth including the depth
of existing contamination and the total depth of the injection wells or infiltration
galleries
See Figures 4-19 through 4-21 of the RFI Report. Information on the existing and proposed injection
locations is summarized in Table 1 and Figure 3-2 of the IM Work Plan report.
_ ! 8.Hydrologic features such as potentiometric surface/water table contours and the
direction of groundwater flow
Refer to the potentiometric surface maps presented in the 2013 Correction Action Monitoring Report
which represents high water table conditions (CDM-Smith, 2013; provided on the enclosed disk).
Additional maps can be found in Figures 4-10, 4-11, 4-32, 4-33, 5-5, and 5-6 of the RFI Report and
Figures 3 and 4 of the 2017 Corrective Action Groundwater Monitoring Report(CDM-Smith 2017).

Attachment F
Engineering Design Documents
1. Engineering plans for the entire system,including treatment, storage, application,and
disposal facilities and equipment except those previously permitted unless they are
directly tied into the new units or are critical to the understanding of the complete
process
Please see the attached permit design drawing set.
2. Specifications describing materials to be used,methods of construction, and means for
ensuring quality and integrity of the finished product
Pertinent and relevant specifications are included on the drawings. Due to the simplicity of the proposed
injection system additional separate specifications are not deemed necessary. A qualified engineer will
oversee the construction.
3. Plans that include construction details of recovery,injection, and monitoring wells and
infiltration galleries.
Please refer to the attached drawings. All new proposed injection wells comply with 15A NVAC
02C.0225(g). Some of the existing thermal points (those used for injection) have been previously UIC
permitted and generally comply with the spirit of the regulations, although the well seal and screening
may differ. Northrop believes that the thermal injection points are adequate for the stated purpose and
Northrop points out that similar thermal points have been successfully used for post thermal
bioremediation injection at other Northrop project locations.

Attachment G
Operating and Monitoring Plans
1. The operating plan shall include:
a. The operating schedule including any periodic shut-down times:
Injection of methanol (or methanol-ethanol blend, and other additives) will be conducted on a batch
basis and roughly be conducted monthly. Injections may become less frequent as the clean-up
progresses and Northrop may elect to conduct more frequent feedings if the clean-up progress is slow.
b. Required maintenance activities for all structural and mechanical elements:
Minimal maintenance will be required beyond occasional well cleaning(surge and bail type).
c. All consumable and waste materials with their intended source and disposal locations:
We do not expect to generate waste material. The only possible waste material to be generated are
solids (precipitated metals/silt/biomass) during well cleaning. If such material is generated it will be
appropriately disposed off site.
d. Restrictions on access to the site and equipment:
Access will be restricted during site feedings using cones and caution tape as needed. All
feedings/injections will be conducted by two operators.
e. Provisions to ensure the quality of the treated effluent and hydraulic control of the
system at all times when any portion of the system ceases to function.
Feedings will be conducted in batch mode and additional provisions are not required since the
injections are manually conducted.
2. If injection wells are to be used then the operating plan shall also include:
a. The proposed average and maximum daily rate and quantity of injectant:
The system will operate in batch addition mode. Each injection location will receive
approximately 50 gallons of methanol (or methanol/ethanol mix)per injection event followed by
injection of approximately 100-1,000 gallons of"chase" water from a potable water source or
other suitable treated water supply. Injection of sodium/potassium hydroxide and di-ammonium
phosphate will be less regular, but will involve injection of diluted additives to solubilize them in
water(50 gallons range),followed by injection of chase water.

b. The average maximum injection pressure expressed in units of pounds per square
inch (psi);
Injection pressures will between 0-20 psi.
a. The total or estimated total volume to be injected.
• Methanol-(electron donor),or methanol-ethanol blend,approximately 20,000 gallons/year
for up to 5 years;
• Contingency electron donor-Emulsified vegetable oil—approximately 10,000 gallons/year
for up to-5 years;
• Potassium/Sodium hydroxide-Estimate 100 gallons/year for 2-3 years;
• Di-Ammonium Phosphate-Estimate 1,500 lbs./year for 2-3 years; and
• KB-1 Dechlorinating Culture-Estimate 260 liters on 2-3 occasions.
3.The monitoring plan shall be prepared in accordance with 15A NCAC 02T.1607 and
include:
All sampling and analysis described in this section will be completed in accordance with the
requirements of the existing project Quality Assurance Project Plan (Conestoga-Rovers & Associates
[CRA] 2010a). Performance monitoring for the IM will be implemented at nine existing groundwater
monitoring wells in close proximity to the proposed remediation areas (PM-1S/D, PM-2S/D, PM-3S/D,
PM-4S/D, PM-5S/D, PM-6S/D, PM-7S/D, PM-8, PM-9S/D, PM-10, MW-12, MW-8, MW-37, MW-32
and RW-4). Additional monitoring wells within the zone of remediation may be installed in
the upcoming year, and if so, those wells will also be sampled. The designated wells will
be sampled on a quarterly basis.
Clean-up performance will be evaluated by assessing indicators of amendment distribution and
longevity, redox parameters and general aquifer geochemistry, and dechlorination activity. Total
organic carbon (TOC) will be used to evaluate amendment distribution and longevity. Dissolved
oxygen (DO), ORP, sulfate, nitrate, total iron, total manganese, sulfide and methane will be used to
evaluate redox conditions in the aquifer. Alkalinity, pH, temperature, chloride, and specific
conductance will also be used to evaluate aquifer geochemical conditions. Chlorinated VOCs, ethene,
ethane, methane will be used to evaluate clean-up progress.

Attachment H
In Situ Remediation Additives

0 0
KOH/NaOH will be a 1%solution. DAP will be a 1/o solution and the bioaugmentation culture
is a 100%solution.

2 Selection rationale:
Please refer to Section 4 of the attached IM Work Plan. As experience with low permeability
project sites (such as the subject site) increased and practitioners experimented with various
electron donors, it became apparent that alcohol (methanol) is likely the best electron donor for
low permeability sites (Falatko et al. 2010, Fam et al. 2012). The alcohol is highly miscible with
water, thus minimizing formation plugging, and since it is a disinfectant if injected as a high
strength solution, it can keep the immediate area around the injection wells relatively clean of
biologic growth,thus minimizing biological fouling in the borehole.
3 Dechlorination reactions:
IESI's experience over the past 20 years indicates that the additives will degrade very rapidly.
The proposed carbon source(methanol or other alcohol blend) is expected to completely degrade
in the subsurface and not migrate out of the treatment zone. The presence of a site-wide
groundwater pump and treat system further ensures that additives will not migrate off site. The
following illustrative equations for the degradation of methanol are provided. The other additives
(emulsified oil or ethanol; if used) degrade to organic acids such as propionate, lactate, and
butyrate which degrade in a similar fashion to the reaction below:
Methanol degradation(anaerobic)
CH3OH(methanol)+2H2O 4 HCO3+H++3H2(hydrogen generating reaction)
3 CH3OH+6 H 4 3CH4+3 H2O(methane generating reaction;hydrogen consuming)
At the subject Site the following sequential reactions are expected to proceed:
Anaerobic CVOC degradation
PCE4 TCE 4 cis-1,2-DCE 4 VC 4 Ethene 4 Carbon Dioxide
Anaerobic dechlorination of PCE to ethene uses hydrogen generated from methanol degradation
as the electron donor, the chlorinated VOC as the electron acceptor, and the reaction is mediated
by ethenogen microorganisms.
Aerobic CVOC co-metabolic degradation
TCE/cis-1,2-DCE/VC+CH4+024CO2 and water
Aerobic co-metabolic methanotrophic degradation of chlorinated VOCs.
Ethene and carbon dioxide are generally considered innocuous end products for the VOC
degradation reactions.

Residual methanol or other carbon substrate is not expected to remain at the conclusion of active
remediation and total organic carbon and organic acid concentrations will degrade soon thereafter
to background concentrations.
4 A Summary of modeling results for injectant transformation:
Methanol anaerobic degradation is widely known(attached reference-Malcolm Pirnie/American
Methanol Institute, 1999). Potassium hydroxide simply adjusts pH. Di-ammonium phosphate is
incorporated into microbial cells/growth.
5 Evaluation of byproducts including increases in naturally occurring compounds.
The target treatment volume is approximately 2.5 to a maximum of 3.3 million gallons.
Potassium/sodium hydroxide will be imported to the Property as a(30-50%)solution in 55 gallon
drums. A small volume of potassium hydroxide, estimated to be less than 5 gallons per week,
will be added into the injection lines and will immediately be diluted and flushed with extraste4—p)/ '-
1.1) 1 groundwater. Potassium/sodium hydroxide transfer will be outdoors and will be conducted using
appropriate chemical resistant drum pumps or metering pumps. During periods of potassium
hydroxide transfer,two operators (wearing safety gear specified in the O&M manual)will be on-
Site to ensure transfer operation safety. Based upon injection of 100 gallons/year of 50%
potassium hydroxide at a density 2.12 g/ml (801 Kg KOH = 7.15 mole KOH = 7.15mole K),
approximately 279 Kg of potassium ion will be added to approximately 3.3 million gallons for a
net concentration increase of 22 mg/L (per year for 1-3 years) of potassium ion - which is
considered negligible. If sodium hydroxide is utilized, similar low amounts of net sodium ion
concentration increase will occur. It is expected that pH will remain in the 6-8 range throughout
the project and will also be neutral after project completion.
Nutrients (N/P)
Nutrients, specifically sources of nitrogen and phosphorus (i.e., di-ammonium phosphate {DAP}
or water soluble Miracle Gros) would be mixed with water and injected into the injection wells
and infiltration trenches during the injection events. The nutrients would immediately be diluted
and flushed with extracted groundwater. We anticipate that the nutrients would be added on a
monthly or every other month basis, at a rate of less than 100 pounds per month for one year.
The actual amounts of nutrients to be added will be based on field conditions and monitoring
results. Based upon addition of 1,000 lbs of DAP,theoretical approximate net increases in N and
P concentrations are 143 and 158 mg/L respectively. Based upon our experience, approximately
90% of the DAP is immobilized by soil adsorption and groundwater concentrations are generally
in the 1-4 mg/L range after additive addition.
No chloride is being added to the subsurface from additives. Since TCE is the primary COC and
based upon an average TCE concentration of 2 mg/L in the volume of groundwater to be treated
(3.3 million gallons), approximately 20.8 kilograms (kg) of TCE is dissolved in groundwater.
Based upon an approximation that soil holds 10 times the groundwater concentration,

approximately 208 Kg of VOCs may be adsorbed to the soil (total groundwater and soil is 228.8
Kg). Approximately 80% of the mass of a TCE molecule is chloride (106.5 of 133.5 molecular
weight). As approximately 183 kg mg) of chloride will be released to the
such, pp Y (183,000,000
groundwater as a result of complete dechlorination. Assuming 2 pore volumes(24,000,000 liters)
receives all the chloride from dechlorination, a net concentration increase of 7.6 mg/L (i.e., =
183,000,000 mg/24,000,000 L) of chloride will be observed in this volume of groundwater. As
this volume of groundwater migrates and disperses,a negligible chloride concentration increase is
expected.
It is expected that approximately 150 gallons of 30%potassium hydroxide for pH buffering will
be added in total.This will result in the addition of 119 kg of potassium to the groundwater. As it
is expected that full dechlorination will occur over two years, approximately 2 pore volumes
(24,000,000 liters)will receive the potassium from potassium hydroxide addition. A net increase
of 5.0 mg/L (i.e., = 119,000,000 mg/24,000,000 L) in the potassium concentration will be
observed in this volume of groundwater. As this volume of groundwater migrates and disperses,
a negligible potassium concentration increase is expected. No other salt or dissolved solids are
expected to be added to the subsurface.
It is expected that pH will remain in the 6-8 range throughout the project and will also be neutral
after project completion. No sulfate compounds will be added to the subsurface.
No metals will be added to the subsurface; however, reducing conditions will enhance metals
(i.e., iron and manganese) solubility. The reducing conditions will be eliminated when carbon
food source is no longer added. The reduced metals will re-oxidize and return to their native state
once they have migrated out of the treatment/transition zones into more aerobic/oxidizing
conditions. As such, there will be no long term change in metals concentrations in the aquifer.
There may be a minor redistribution of native aquifer metals(mainly iron and manganese),as the
dissolved metals may migrate from one part of the aquifer to another (possibly about 300 feet).
This redistribution of iron/manganese is considered minor,incidental,and temporary.

Potential Acute Health Effects:
Eye Contact: Causes mild to moderate eye irritation. High vapor concentration or liquid contact with eyes causes irritation,
tearing and burning.
Skin Contact: Causes moderate skin irritation. May be absorbed through the skin in toxic or lethal amounts. Symptoms of
exposure may include: Central nervous system depression with headache, stupor, uncoordinated or strange behaviour or
unconsciousness. Prolonged and or repeated skin contact with methanol soaked material has produced toxic effects
including vision effects and death.
LA1183

3. HAZARDS IDENTIFICATION
Inhalation: Inhalation of high airborne concentrations can irritate mucous membranes, cause headaches, sleepiness,
nausea, confusion, loss of consciousness, digestive and visual disturbances and death. NOTE: Odour threshold of
methanol is several times higher than the TLV-TWA. Depending upon severity of poisoning and the promptness of
treatment, survivors may recover completely or may have permanent blindness, vision disturbances and/or nervous
system effects. Concentrations in air exceeding 1000 ppm may cause irritation of the mucous membranes.
Ingestion: May be fatal if swallowed.A small amount of methanol(usually two or more ounces)can cause mental
sluggishness, nausea and vomiting leading to severe illness, and may produce adverse effects on vision with possible
blindness or death if treatment is not received.Aspiration into the lungs may occur during ingestion or vomiting, resulting in
lung injury.
4. FIRST AID MEASURES .
Eye Contact: Remove contact lenses, if worn. Flush immediately with gentle running water for a minimum of 15 minutes,
'---i ensuring all surfaces and crevices are flushed by lifting lower and upper lids. Obtain medical attention.
Skin Contact: Remove contaminated clothing and shoes. In case of contact, immediately flush skin with plenty of soap
and water for at least 15 minutes. If irritation persists get medical attention. Wash clothing before reuse. Thoroughly clean
contaminated shoes. Prolonged contact with methanol may defat skin tissue, resulting in drying and cracking.
Inhalation: Remove to fresh air, restore or assist breathing if necessary, obtain medical attention immediately.
Ingestion: If swallowed, do not induce vomiting. Never give anything by mouth to an unconscious person. Obtain medical
help immediately. Onset of symptoms may be delayed for 18 to 24 hours after ingestion. Swallowing methanol is life
threatening.
Notes to Physician:Acute exposure to methanol, either through ingestion or breathing high airborne concentrations can
result in symptoms appearing between 40 minutes and 72 hours after exposure. Symptoms and signs are usually limited
to CNS, eyes and gastrointestinal tract. Because of the initial CNS's effects of headache, vertigo, lethargy and confusion,
there may be an impression of ethanol intoxication. Blurred vision, decreased acuity and photophobia are common
complaints. Treatment with ipecac or lavage is indicated in any patient presenting within two hours of ingestion.A profound
metabolic acidosis occurs in severe poisoning and serum bicarbonate levels are a more accurate measure of severity than
serum methanol levels. Treatment protocols are available from most major hospitals and early collaboration with
appropriate hospital is recommended. In cases of methanol poisoning, medical care must emphasize the control of
acidosis. The use of intravenous bicarbonate has been lifesaving. Evidence shows that the treatment of methanol
absorption is enhanced through the administration of ethanol,which should be given to produce a blood level of at least
0.1%. Ethanol diminishes the production of the toxic metabolites of methanol. A blood methanol level of 50 mg/100m1 is
an indication for hemodialysis,which has improved the prognosis of methanol intoxification. If more than 2.0 mL/kg has
been ingested, vomiting should be induced with supervision.
5. FIRE FIGHTING MEASURES
Flash Point: 11 °C/52°F
Flash Point Method: Tag Closed Cup
Autoignition Temperature: 385°C/725°F
Flammable Limits in Air(%): Lower: 6% Upper: 36%
Extinguishing Media: Small fires: Dry chemical, CO2,water spray Large fires:Water spray(see note in Unsuitable
Extinguishing Media),AFFF(R) (Aqueous Film Forming Foam (alcohol resistant))type with either a 3% or 6%foam
proportioning system.
Unsuitable Extinguishing Media: General purpose synthetic foams or protein foams may work, but much less effectively.
Water may be effective for cooling, but may not be effective for extinguishing a fire because it may not cool methanol
below its flash point.
Special Exposure Hazards: Flammable Liquid. Isolate and restrict area access. Stay upwind. Methanol burns with a
clean clear flame that is almost invisible in daylight. Concentrations of greater than 25% methanol in water can be ignited.
Use fine water spray or fog to control fire spread and cool adjacent structures or containers. Contain fire control water for
later disposal.Vapors are heavier than air and may accumulate in low areas.Vapors may travel along the ground to be
ignited at distant locations. Closed containers may rupture violently or explode and suddenly release large amounts of
product when exposed to fire or excessive heat for a sufficient period of time.
Hazardous Decomposition/Combustion Materials(under fire conditions): Carbon monoxide. Carbon dioxide.
Formaldehyde.

5. FIRE FIGHTING MEASURES
Special Protective Equipment: Fire fighters must wear full face, positive pressure, self-contained breathing apparatus
and appropriate protective clothing. Note that methanol fires may require proximity suits. Do not walk through spilled
product. Thoroughly decontaminate bunker gear and other fire-fighting equipment before re-use.
NFPA RATINGS FOR THIS PRODUCT ARE: HEALTH 1, FLAMMABILITY 3, INSTABILITY 0
HMIS RATINGS FOR THIS PRODUCT ARE: HEALTH 1, FLAMMABILITY 3, REACTIVITY 0
6. ACCIDENTAL RELEASE MEASURES
Personal Precautionary Measures: Full-face, positive pressure self-contained breathing apparatus or airline and
protective clothing must be worn.
Environmental Precautionary Measures: Prevent from entering into soil, ditches, sewers,waterways and/or
groundwater. Consult local authorities. Biodegrades easily in water. Methanol in fresh or salt water may have serious
effects on aquatic life.A study on methanol's toxic effects on sewage sludge bacteria reported little effect on digestion at
_- 0.1%while 0.5% methanol retarded digestion. Methanol will be broken down to carbon dioxide and water.
Procedure for Clean Up: Flammable liquid. Eliminate all ignition sources. Isolate hazard area and restrict access. Stop
leak only if safe to do so. Do not walk through spilled product as it may be on fire and not visible. Release can cause an
immediate fire/explosion hazard. Fluorocarbon alcohol resistant foams may be applied to spill to diminish vapour and fire
hazard. Maximize recovery for recycling or reuse. Restrict access to unprotected personnel. Ensure clean-up is conducted
by trained personnel only. Ensure disposal is in compliance with all applicable government requirements. Small spills: soak
up with absorbent material and scoop into containers. Large spills : prevent contamination of waterways. Dike and pump
into suitable containers. Clean up residual with absorbent material, place in appropriate container and flush with water.
7. HANDLING AND STORAGE
Handling: For industrial use only. Handle and open containers with care.Avoid contact with eyes, skin and clothing. Do
not ingest.Avoid inhalation of chemical. DO NOT handle or store near an open flame, heat, or other sources of ignition.
Fixed equipment as well as transfer containers and equipment should be grounded to prevent accumulation of static
charge. DO NOT pressurize, cut, heat, or weld containers. Empty containers may contain hazardous product residues.
Keep the containers closed when not in use. Protect against physical damage. Use appropriate personnel protective
equipment.
Storage: Store in a cool, dry,well ventilated area, away from heat and ignition sources. Place away from incompatible
materials. Tanks must be grounded and vented and should have vapour emission controls. Tanks must be diked.A
flammable mixture of methanol vapour and air is possible inside a storage tank or transportation tank, and handlers should
take appropriate precautions to reduce the risk of ignition. Handlers must eliminate ignition sources or purge the tank with
an inert gas such as nitrogen.All equipment must be grounded-bonded when transferring product in order to avoid static
discharge from the equipment, and subsequent possible fire.Anhydrous methanol is non-corrosive to most metals at
ambient temperatures except for lead, nickel, monel, cast iron and high silicon iron. Coatings of copper(or copper alloys),
zinc(including galvanized steel), or aluminum are unsuitable for storage. These materials may be attacked slowly by the
methanol. Storage tanks of welded construction are normally satisfactory. They should be designed and built in
conformance with good engineering practice for the material being stored. While plastics can be used for short term
storage,they are generally not recommended for long-term storage due to deterioration effects and the subsequent risk of
contamination.
Corrosion rates for several construction materials:
<0.508 mm/year: Cast iron, monel, lead, nickel
<0.051 mm/year: High silicon iron
Some attack: Polyethylene
Satisfactory: Neoprene, phenolic resins, polyesters, natural rubber, butyl rubber
Resistant: Polyvinyl chloride, unplasticized

11. TOXICOLOGICAL INFORMATION
Principle Routes of Exposure
Ingestion: May be fatal if swallowed.A small amount of methanol (usually two or more ounces)can cause mental
sluggishness, nausea and vomiting leading to severe illness, and may produce adverse effects on vision with possible
blindness or death if treatment is not received.Aspiration into the lungs may occur during ingestion or vomiting, resulting in
lung injury.
Skin Contact: Causes moderate skin irritation. May be absorbed through the skin in toxic or lethal amounts. Symptoms of
exposure may include: Central nervous system depression with headache, stupor, uncoordinated or strange behaviour or
unconsciousness. Prolonged and or repeated skin contact with methanol soaked material has produced toxic effects
including vision effects and death.
Inhalation: Inhalation of high airborne concentrations can irritate mucous membranes, cause headaches, sleepiness,
nausea, confusion, loss of consciousness, digestive and visual disturbances and death. NOTE: Odour threshold of
methanol is several times higher than the TLV-TWA. Depending upon severity of poisoning and the promptness of
treatment, survivors may recover completely or may have permanent blindness, vision disturbances and/or nervous
system effects. Concentrations in air exceeding 1000 ppm may cause irritation of the mucous membranes.
Eye Contact: Causes mild to moderate eye irritation. High vapor concentration or liquid contact with eyes causes irritation,
tearing and burning.
Additional Information:
Repeated exposure by inhalation or absorption of methanol may cause systemic poisoning, brain disorders, impaired
vision and blindness. Inhalation may worsen conditions such as emphysema or bronchitis. Repeated skin contact may
cause dermal irritation, dryness and cracking. Effects of sub lethal doses may be nausea, headache, abdominal pain,
vomiting and visual disturbances ranging from blurred vision to light sensitivity. Methanol is toxic by inhalation and
ingestion. Inhalation of vapors may cause cyanosis, CNS effects, lethargy, loss of consciousness and death. The effects
from inhalation may be delayed. Ingestion may cause malaise, CNS effects, discomfort, and death if not treated promptly.
Ingestion of methanol has resulted in adverse effects(necrosis and haemorrhaging) in the brain. Medical conditions
aggravated by exposure include: skin disorders and allergies, liver disorders and eye disease. Undocumented reports
suggest that this product may form a siloxane polymer on the eyes, lungs, or other mucous membranes. Long term
exposure to methanol has been associated with headaches, giddiness, conjunctivitis, insomnia and impaired vision.
Dermal absorption of significant amounts of methanol resulted in death in several animal species. Toxic effects in animals
exposed to methanol by inhalation include eye irritation, blindness and nasal discharge. Toxic effects observed in animals
exposed to methanol by ingestion include CNS effects , gastrointestinal effects, anesthetic effects, damage to the optic
nerve and acidosis.
_ Synergistic Products: In animals, high concentrations of methanol can increase the toxicity of other chemicals, particularly
liver toxins like carbon tetrachloride. Ethanol significantly reduces the toxicity of methanol because it competes for the
same metabolic enzymes, and has been usd to treat methanol poisoning.
Potential for Accumulation: Methanol is readily absorbed into the body following inhalation and ingestion. Skin absorption
may occur if the skin is broken or exposure is prolonged. Once absorbed, methanol is rapidly distributed to body tissues.A
small amount is excreted unchanged in exhaled air and the urine. The rest is first metabolized to formaldehyde,which is
then metabolized to formic acid and/or formate. The formic acid and formate are eventually converted to carbon dioxide
and water. In humans, methanol clears from the body, after inhalation or oral exposure,with a half-life of 1 day or more for
high doses (greater than 1000 mg/kg)or about 1.5-3 hours for low doses(less than 100 mg/kg or 76.5-230 ppm (100-300
mg/m3))•

Special Information:
In the event of a fire,wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand
or other positive pressure mode.
6.Accidental Release Measures
Ventilate area of leak or spill.Keep unnecessary and unprotected people away from area of spill.Wear appropriate personal protective equipment as specified in
Section 8.Spills:Pickup and place in a suitable container for reclamation or disposal,using a method that does not generate dust.Do not flush caustic residues to
the sewer.Residues from spills can be diluted with water,neutralized with dilute acid such as acetic,hydrochloric or sulfuric.Absorb neutralized caustic residue
on clay,vermiculite or other inert substance and package in a suitable container for disposal.
US Regulations(CERCLA)require reporting spills and releases to soil,water and air in excess of reportable quantities.The toll free number for the US Coast
Guard National Response Center is(800)424-8802.
7.Handling and Storage
Keep in a tightly closed container.Protect from physical damage.Store in a cool,dry,ventilated area away from sources of heat,moisture and incompatibilities.
Always add the caustic to water while stirring;never the reverse.Containers of this material maybe hazardous when empty since they retain product residues
, (dust,solids);observe all warnings and precautions listed for the product.Do not store with aluminum or magnesium.Do not mix with acids or organic materials.
8.Exposure Controls/Personal Protection
Airborne Exposure Limits:
-OSHA Permissible Exposure Limit(PEL):
2 mg/m3 Ceiling
-ACGIH Threshold Limit Value(TLV):
2 mg/m3 Ceiling
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits.Local exhaust ventilation is
generally preferred because it can control the emissions of the contaminant at its source,preventing dispersion of it into the general work area.Please refer to the
ACGIH document,Industrial Ventilation,A Manual of Recommended Practices,most recent edition,for details.
Personal Respirators(NIOSH Approved):
If the exposure limit is exceeded and engineering controls are not feasible,a half facepiece particulate respirator(NIOSH type N95 or better filters)may be worn
for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier,whichever is
lowest.A full-face piece particulate respirator(NIOSH type N100 filters)may be worn up to 50 times the exposure limit,or the maximum use concentration
specified by the appropriate regulatory agency,or respirator supplier,whichever is lowest.If oil particles(e.g.lubricants,cutting fluids,glycerine,etc.)are
present,use a NIOSH type R or P filter.For emergencies or instances where the exposure levels are not known,use a full-facepiece positive-pressure,air-
supplied respirator.WARNING:Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection:
Wear impervious protective clothing,including boots,gloves,lab coat,apron or coveralls,as appropriate,to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is possible.Maintain eye wash fountain and quick-drench facilities in work area.

Eye Contact: Flush eyes with water for at least 15 minutes, occasionally lift upper and lower
eyelids, if undue irritation or redness occurs seek medical attention.
Skin Contact: Remove contaminated clothing and wash skin thoroughly with water and
antibacterial soap. Seek medical attention if irritation develops or open wounds are present.
Ingestion: Do not induce vomiting, drink several cups of water, seek medical attention.
Inhalation: Remove to fresh air. If not breathing give artificial respiration. In case of labored
breathing give oxygen. Call a physician.
Section 5-Fire Fighting Measures:
Non-flammable
Flash Point: not applicable
Upper flammable limit: not applicable
Lower flammable limit: not applicable
Section 6—Accidental Release Procedures
Spilled KB-i®Dechlorinator should be soaked up with sorbant and saturated with a 10%
bleach solution (prepared by making a one in ten dilution of diluted standard bleach
[normally sold at a strength of 5.25% sodium hypochlorite] to disinfect affected surfaces.
Sorbant should be double bagged and disposed of as indicated in section 12. After
removal of sorbant, area should be washed with 10% bleach solution to disinfect. If liquid
from the culture vessel is present on the fittings, non-designated tubing or exterior of the
stainless steel pressure vessel liquid should be wiped off and the area washed with 10%
bleach solution.
Section 7 - Handling and Storage
KB1® Dechlorinator is shipped in stainless steel pressure vessels and connected to
injection lines and inert gas is used to pressurize the vessel to displace the contents. KB-
Dechlorinator should be handled with care to avoid any spillage. Vessels are shipped
with 1 pound per square inch (psi) pressure; valves should not be opened until
connections to appropriate lines for subsurface injection are in place.
Storage Requirements: Avoid exposing stainless steel pressure vessels to undue
temperature extremes (i.e., temperatures less than 0°C or greater than 30°C may result
in harm to the microbial cultures and damage to the vessels). All valves should be in the
closed position when the vessel is not pressurized to prevent the escape of gases and to
maintain anaerobic conditions in the vessel. Avoid exposure of the culture to air as the
presence of oxygen will kill dechlorinating microorganisms.
Section 8 - Exposure Controls/Personal Protection
Personal protective equipment:
Skin: Protective gloves(latex, vinyl or nitrile)should be worn.
Eye Protection: Wear appropriate protective eyeglasses or goggles when opening
pressure vessels valves or when pressurizing vessels to inject contents into the

t ; 4. FIRST AID MEASURES
FIRST AID MEASURES FOR ACCIDENTAL:
Eye Exposure:
Hold eyelids open and flush with a steady, gentle stream of water for at least 15 minutes. Seek medical attention
if irritation develops or persists or if visual changes occur.
Skin Exposure:
In case of contact, immediately wash with plenty of soap and water for at least 5 minutes. Seek medical attention
if irritation developes or persists. Remove contaminated clothing and shoes. Clean contaminated clothing and
shoes before re-use.
Inhalation:
If respiratory irritation or distress occurs remove victim to fresh air. Seek medical attention if respiratory irritation
or distress continues.
Ingestion:
Do not induce vomiting, unless directed to do so by a physician. If victim is conscious and alert, give 2-3 glasses
of water to drink. Seek immediate medical attention. Do not leave victim unattended. To prevent aspiration of
swallowed product, lay victim on side with head lower than waist.Vomiting may occur spontaneously. If vomiting
occurs and the victim is conscious, give water to further dilute the chemical.Also see Note To Physician.
MEDICAL CONDITIONS POSSIBLY AGGRAVATED BY EXPOSURE:
Inhalation of product may aggravate existing chronic respiratory problems such as asthma, emphysema or
bronchitis. Skin contact may aggravate existing skin disease.
NOTES TO PHYSICIAN:
All treatments should be based on observed signs and symptoms of distress in the patient. Consideration should
be given to the possibility that overexposure to materials other than this product may have occurred.
Ingestion of large quantities of phosphate salts(over 1.0 grams for an adult) may cause an osmotic catharsis
resulting in diarrhea and probable abdominal cramps. Larger doses such as 4-8 grams will almost certainly cause
these effects in everyone. In healthy individuals most of the ingested salt will be excreted in the feces with the
diarrhea and, thus, not cause any systemic toxicity. Doses greater than 10 grams hypothetically may cause
systemic toxicity. Treatment should take into consideration both anionic and cation portion of the molecule. The
following treatments should be considered for the specific group(s)of phosphate salts found in this product:
—All phosphate salts, except calcium salts, have a hypothetical risk of hypocalcemia, so calcium levels should be

DIAMMONIUM PHC, Page 3 of 9
monitored.
—Ammonium salts have a hypothetical risk of ammonia toxicity. In addition to calcium levels, ammonia and
phosphate levels should be monitored.
—Potassium salts have a hypothetical risk of hyperkalemia which can cause cardiac arrhythmia. In addition to
calcium levels, potassium and phosphate levels should be monitored.Also consider continuous EKG monitoring
to detect hyperkalemia.
—Sodium salts have a hypothetical risk of hypernatremia. In addition to calcium levels, sodium and phosphate
levels should be monitored.

Hi Michael-
Yes you are correct that the system influent/effluent sampling is still part of the permit. When we submitted the
modification package earlier in the year, we were focused on the modifications and not the existing (pump and treat)
system. Since the package is now being used for renewal as well, it should certainly include the system influent/effluent
sampling.

Attached is the monitoring plan Table G-1 from the permit issued in 2014. I do not see any reference in the permit
modification application or subsequent additional information received in regards to monitoring the treatment
system. Unless I am missing seeing it, monitoring plan tables received to date do not include influent or effluent
monitoring. Any reason why?
Please put the permit number in subject line of all emails for this permit so they can be searched and retrieved in

Re: UIC Permit Modification-Response to Information Request#2
Permit#WQ0036881
Former Clifton Precision Site—Murphy,NC
Dear Mr. Rogers:
This letter provides additional information/clarification pertaining to the permit modification application to permit#
WQ0036881. The permit modification request was submitted to the North Carolina Department of Environmental
Resources(NC DENR)on March 30,2018. The letter addresses several topics that we discussed during phone calls
on September 25 and 26,2018.
1. Permit#WQ0036881 expires on April 11,2019 and a renewal application is due to NC DENR on October
11, 2019 (6 months prior to permit expiration). In consideration that the NC DENR is currently reviewing
the permit, Northrop Grumman Guidance and Electronics Company, Inc. hereby requests that the permit
modification request also simultaneously be processed as a request for permit renewal.
2. Attached,please find an updated site layout(Figure 1). The updated figure includes all new proposed well
locations(injection {liquids and oxygen} and monitoring)associated with the proposed permit modification.
The various new and existing wells in the vicinity and the type of injection well(liquid or oxygen)are color
coded for clarity. In addition,the figure shows the location of the currently operating pumping and injection
wells associated with the existing pump and treat system. Figure 2a shows the existing monitoring wells that
are associated with the existing pump and treat monitoring program. Combining all of the wells on one figure
was deemed too busy/confusing.
3. Attached please find an updated well construction table(Table 1A). The table has been updated to include
all proposed monitoring locations associated with the permit modification,proposed oxygen injection wells,
as well as the existing extraction and injection wells associated with the existing pump and treat system. The
table in the original submittal only included proposed liquid injection locations. Table 3 (attached)lists well
construction information for monitoring locations associated with the existing pump and treat system.
4. The proposed groundwater monitoring program is clarified as follows: The existing groundwater monitoring
program will remain in place without modification. The existing groundwater monitoring program is
summarized in Table 1 (attached). In order to monitor the progress of the proposed modification, a
supplemental monitoring program is proposed and is summarized in Table 2.
Offices in Boston,Portland and Nashua www.IESIonline.com

i ! 5. The well construction figure(Figure 8)has been updated to include average expected screen and well casing
lengths. As discussed on the phone,these average lengths will likely vary depending upon field conditions
and final lengths will be updated in the as-built drawings.
We hope that this letter clarifies the items that we discussed,and we thankyou foryour continued support.

Hi Andy-
Thanks for your quick review and comments regarding our permit modification request. We have compiled
some questions/clarifications about your comments and also responded to some of the simple
2

I
• questions. Once we receive your response to this email, we will compile a more formal response by letter that
should satisfy the Division of Water Resources (DWR).
Comment#1: Well construction details:The well construction details D and E provided on Figure 10 for the
top of grout and grout/seal type are a mistake,the details A and B provided on Figure 8 correctly show how
we want to construct the wells in regards to the grout type and depth. Our intent is to use a bentonite-
amended Portland cement grout mixed in the ratios and manner described on Figure 8 and set to the depths
as noted on Figure 8. All of these wells will be located in high traffic areas, so they all have to be finished with
flush-mounted well vaults, so the grout has to be terminated some distance below grade to allow connections
to the well and install the well vault. Our standard approach for a remedial injection well is to install a pitless
adapter at 3-feet below grade to protect the pipe and prevent water pipes from freezing inside the vault, so
terminating the grout at 4-feet below grade allows some working space above the grout to install the pitless
adapter. For the sparge well, we typically connect the sparge gas line to the well below grade and below the
inside of the well vault at 1.5-feet below grade to protect the connection and minimize the chance of breaking
the high pressure gas line connection to the well, so we show the grout placed to 3-feet below grade to allow
for this connection to be made, however,we can raise the grout level for the sparge wells to 2-feet below
grade and still have working space above it.
Comment#2: Well head piping and connections:As discussed in our response to comment#1, we prefer to
have connections to the well below grade and below the inside of the well vault to protect the pipe and
associated connections. We understand the concern and intent of the regulations in regards to surficial
contaminants entering the well, so we do completely seal the wells with threaded PVC fittings at the top, and
the side connections use compression 0-rings to create a liquid-tight seal on the pitless adapter (remedial
injection well) and the saddle fitting (sparge well). All of the fittings are considered liquid-tight fittings, and
the use of PVC well casing allows for these connections to seal the well completely once installed.
Comment#3: Grout seal for sparge wells: Detail E on Figure 10 when it refers to the top of bentonite hole-plug
is a mistake, detail B on Figure 8 shows our intended construction for the sparge wells;to bring the grout up to
3-feet below grade. Our reasoning for the depth to the top of grout for both remedial injection wells and
sparge wells was discussed in the previous responses. However, as noted previously, we will raise the depth to
the top of grout for the sparge wells to 2-feet below grade as this should still allow the side connection to the
well.
Comment#4: Sampling Locations: Northrop proposed installing additional wells near wells MW-12 and MW-
18 in the Interim Measures Plan and as shown on Figure 3 in the design drawings of the UIC permit
modification. We will clarify the text that these new wells are being proposed/sampled. In summary, we will
sample the wells listed in section`F3-ofpermrt modificationvpaus the_n>ewwellssnearIVIVV=B-and NIMW 12 'and
continuemith,..the,existing monitorin&plarr(April=18;.2014.version).
Comment#5: We acknowledge that once the sampling plan is approved, it cannot be reduced. We may add
selected additional monitoring wells as needed.
Comment#6: Northrop Submitted Risk Assessment Evaluation of Groundwater or Soil Remediation Additives
Containing for Methanol addition on April 9, 2018. (cover letter attached). With regards to the other additives
mentioned in the comment letter:
Section H-1 summarizes that we expect to use 1) DAP (approved additive). Miracle grow is essentially
solubilized DAP. If the DWR prefers that we use DAP and not Miracle grow that is easy to do, 2) Section H1
3

states that may use sodium or potassium hydroxide. Those are both essentially the same (hydroxide base). If
the DWR prefers sodium hydroxide, we can use that, although potassium hydroxide is less reactive with clays
and is slightly preferable. 3) Muriatic acid/HCI is not an additive and is only used to clean the wells (as
needed). Once the cleaning is completed,the acid is pumped out. If the DWR prefers, we can use sulfuric
acid, which is an approved additive.
Comment#7:
No groundwater injection is proposed. The word groundwater is a typographical error and should be tap-
water

Re: UIC Permit Modification
Risk Assessment Evaluation of Groundwater or Soil Remediation Additives Containing no Microorganisms
Dosing Estimates
Permit#WQ0036881
Former Clifton Precision Site—Murphy,NC
Dear Mr.Rogers:
This letter clarifies the expected additive mixture as proposed in the UIC permit modification as well as the Interim
Measure(IM)Work Plan that was submitted to US EPA in February 2018. We typically do not explicitly state how
the system will be operated since additive dosing is dependent upon groundwater conditions, and as such additive
dosing may change during the course of the clean-up. It is our understanding that the DHSS requires more specific
information and we provide such details in this letter.
At the project outset, a typical injection event (no more than every 2 weeks) will include:
• 750-1,050 gallons of Methanol/Ethanol (roughly 50% each pre-blended by vendor) blend (no more than
20,000 gallons per year;ethanol is a pre-approved additive)
• o
3-5 gallons of 50%Sodium Hydroxide(NaOH;no more than 100 gallons/year;pre-approved additive)
• 40-80 lbs.of Di-Ammonium Phosphate(DAP;no more than 1,500 lbs.year;pre-approved additive)
We will initially use the ethanol/methanol blend since ethanol is a better sulfate reduction substrate. Once most of
the sulfate has been reduced (after approximately 6-12 months) we will likely substitute pure methanol for the
methanol/ethanol blend and as such a typical injection event will be:
• 750-1,050 gallons of Methanol(no more than 20,000 gallons per year)
• 3-5 gallons of 50%sodium hydroxide(no more than 100 gallons/year;pre-approved additive)
• 40-80 lbs.of di-ammonium phosphate(no more than 1,500 lbs.year;pre-approved additive)
Once anaerobic conditions have been established, we will bioaugment with KB-1 culture (pre-approved additive).
The KB-1 culture(260 liters)will be added 2-3 times over the course of the first 3 years of operation.
The UIC permit modification application also call for using acid(sulfuric {pre-approved additive} as a substitute for
hydrochloric) for occasional well cleaning. Any acid that is added will be removed for off site disposal following
overnight treatment. Lastly the UIC permit modification application calls for use of emulsified vegetable oil (pre-
approved additive)as a substitute for methanol and methanol/ethanol,however this will unlikely be used.

Additive Rationale
The alcohol is the main electron donor and the DAP and NaOH are additives to ensure that the electron donor degrades
at optimal conditions. The DAP provides essential inorganic nutrients and the NaOH maintains a neutral pH. As
such, injection of the additives together is essential for•project success. The UIC modification application
(Attachment H, Section 5) details the fate of the additives and concludes that the injection will have no long term
deleterious effects on groundwater quality. Below is an excerpt(modified for sodium as a substitute for potassium
hydroxide and the resultant concentrations)from the discussion:
Sodium hydroxide will be imported to the Property as a(30-50%) solution in 55-gallon drums. A small volume of
sodium hydroxide,estimated to be less than 5 gallons per week,will be added(mixed in tap water)into the injection
lines and will immediately be diluted and flushed with tap water. Sodium hydroxide transfer will be outdoors and
will be conducted using appropriate chemical resistant drum pumps or metering pumps. During periods of sodium
hydroxide transfer, two operators (wearing safety gear specified in the O&M manual) will be on-Site to ensure
transfer operation safety. Based upon injection of 100 gallons/year of 50%sodium hydroxide at a density 2.12 g/ml
(100 gallons x 3.78 L/gallon x 0.5 x 2.12 Kg/L=400 Kg NaOH= 10 mole NaOH= 10 mole Na),approximately 230
Kg of sodium ion will be added to approximately 3.3 million gallons (of groundwater in 1 pore volume) for a net
concentration increase of 18.5 mg/L (per year for 1-3 years) of sodium ion - which is considered negligible. It is
expected that pH will remain in the 6-8 range throughout the project and will also be neutral after project completion.
Nutrients, specifically sources of nitrogen and phosphorus (i.e., di-ammonium phosphate {DAP}) would be mixed
with water and injected into the subsurface during the injection events. The nutrients (mixed in tap water) would
immediately be further diluted and flushed with tap water. We anticipate that the nutrients would be added on a
monthly or every other month basis,at a rate of less than 100 pounds per month for one year. The actual amounts of
nutrients to be added will be based on field conditions and monitoring results. Based upon our experience,
approximately 90% of the DAP is immobilized by soil adsorption and groundwater concentrations are generally in
the 1-4 mg/L range after additive addition.
We hope that this letter clarifies the proposed injections and enables approval of the UIC modification application •,
Thank you for your help.

Hi Andy-
Thanks for your quick review and comments regarding our permit modification.request. We have compiled
some questions/clarifications about your comments and also responded to some of the simple
questions. Once we receive your response to this email, we will compile a more formal response by letter that
should satisfy the Division of Water Resources (DWR).
Comment#1: Well construction details:The well construction details D and E provided on Figure 10 for the
top of grout and grout/seal type are a mistake,the details A and B provided on Figure 8 correctly show how
we want to construct the wells in regards to the grout type and depth. Our intent is to use a bentonite-
amended Portland cement grout mixed in the ratios and manner described on Figure 8 and set to the depths
as noted on Figure 8. All of these wells will be located in high traffic areas, so they all have to be finished with
flush-mounted well vaults, so the grout has to be terminated some distance below grade to allow connections
to the well and install the well vault. Our standard approach for a remedial injection well is to install a pitless
adapter at 3-feet below grade to protect the pipe and prevent water pipes from freezing inside the vault, so
terminating the grout at 4-feet below grade allows some working space above the grout to install the pitless
adapter. For the sparge well, we typically connect the sparge gas line to the well below grade and below the
inside of the well vault at 1.5-feet below grade to protect the connection and minimize the chance of breaking
the high pressure gas line connection to the well, so we show the grout placed to 3-feet below grade to allow
for this connection to be made, however, we can raise the grout level for the sparge wells to 2-feet below
grade and still have working space above it.
Comment#2: Well head piping and connections:As discussed in our response to comment#1, we prefer to
have connections to the well below grade-and below the inside of the well vault to protect the`pipe and
associated connections. We understand the concern and intent of the regulations in regards to surficial
contaminants entering the well, so we do completely seal the wells with threaded PVC fittings at the top, and.
the side connections use compression 0-rings to create a liquid-tight seal on the pitless adapter (remedial
injection well) and the saddle fitting (sparge well). All of the fittings are considered liquid-tight fittings, and
the use of PVC well casing allows for these connections to seal the well completely once installed.
Comment#3: Grout seal for sparge wells: Detail E on Figure 10 when it refers to the top of bentonite hole-plug
is a mistake, detail B on Figure 8 shows our intended construction for the sparge wells;to bring the grout up to
3-feet below grade. Our reasoning for the depth to the top of grout for both remedial injection wells and
sparge wells was discussed in the previous responses. However, as noted previously,we will raise the depth to
the top of grout for the sparge wells to 2-feet below grade as this should still allow the side connection to the
well.
Comment#4: Sampling Locations: Northrop proposed installing additional wells near wells MW-12 and MW-
18 in the Interim Measures Plan and as shown on Figure 3 in the design drawings of the UIC permit
modification. We will clarify the text that these new wells are being proposed/sampled. In summary, we will
sample the wells listed in section G3 of permit modification plus the new wells-near MW-8 and MW-12 and
continue with the existing monitoring plan (April 18, 2014 version).
Comment#5: We acknowledge that once the sampling plan is approved, it cannot be reduced. We may add
selected additional monitoring wells as needed.

Comment#6: Northrop Submitted Risk Assessment Evaluation of Groundwater or Soil Remediation Additives
Containing for Methanol addition on April 9, 2018. (cover letter attached). With regards to the other additives
mentioned in the comment letter:
Section H-1 summarizes that we expect to use 1) DAP (approved additive). Miracle grow is essentially
solubilized DAP. If the DWR prefers that we use DAP and not Miracle grow that is easy to do, 2) Section H1
states that may use sodium or potassium hydroxide. Those are both essentially the same (hydroxide base). If
the DWR prefers sodium hydroxide, we can use that, although potassium hydroxide is less reactive with clays
and is slightly preferable. 3) Muriatic acid/HCI is not an additive and is only used to clean the wells (as
needed). Once the cleaning is completed,the acid is pumped out. If the DWR prefers, we can use sulfuric
acid, which is an approved additive.
Comment#7:
No groundwater injection is proposed. The word groundwater is a typographical error and should be tap-
water

Sami,
Thank you for your questions/clarifications to the Division's Additional Information Request. Follow-up comments are
below.
Comment#1—The discrepancy between Figure 8 and Figure 10 has been resolved.The remedial wells as proposed, do
not meet the well constructions standard in 15A NCAC 02C .0225(g)(9)(B).The Division has determined that the
proposed well construction, as described below and on the referenced figures,will satisfy the requirements for a
variance as provided in 15A NCAC 02C .0241.The well construction variance will be incorporated into the permit once
revised as provided in 15A NCAC 02C .0241(d).
Comment#2—The Division is satisfied that the design will preclude surficial contaminants from entering the wellhead
and the wells may be constructed as proposed with respect to piping.
Comment#3—The discrepancy between Figure 8 and Figure 10 has been resolved.The air injection wells as proposed,
do not meet the well constructions standard in 15A NCAC 02C .0225(b)(4)(B)or 15A NCAC 02C.0108(i).The Division has
determined that the proposed well construction, as described below and on the referenced figures,will satisfy the
requirements for a variance as provided in 15A NCAC 02C .0241.The well construction variance will be incorporated into
the permit once revised as provide in 15A NCAC 02C .0241(d).
Comments#4 and#5—The proposed monitoring plan as described below has been clarified and is acceptable.

Subject: Permit Modification Application Additional Information Request
Non-Discharge Groundwater Remediation Permit
Permit No. WQ0036881
Former Clifton Precision Site
Cherokee County
Dear Mr. Williams:
After inspection of the site and review of the permit modification application, most of the needed
information is in the application. However,there are several areas that need clarification and additional
information. We have the following comments/requests:
• Detail A Figure 8, and Detail D Figure 10 do not appear to match each other with respect to
grout type and grout depth from land surface. Nor do they appear to meet 15A NCAC 02C
.0225(g)(9)(B), which requires grout to land surface. Please clarify or propose modifications
to well construction.
• 15A NCAC 02C .0225(g)(22) requires that all piping, wiring, and vents shall enter the well
through the top of the casing unless otherwise approved by the Director based on a design
demonstrated to preclude surficial contaminants from entering the wellhead. Please provide
any reasons why remedial wells cannot be constructed to this rule, or propose well design
modifications.
• 15A NCAC 02C .0225(b)(4)(B) requires that air injection wells be constructed in accordance
with the well construction standards applicable to monitoring wells specified in 02C .0108.
15A NCAC 02C .0108(i) requires that grout be placed in the annular space between the
outermost casing, and the borehole wall from the land surface to the top of the bentonite seal.
Detail B Figure 8 of the application shows the top of the cement grout at 3 feet below ground
surface,whereas Detail E Figure 10 of the application only shows bentonite holeplug to 6 feet
below ground surface. Please clarify or propose well design modifications.

• The proposed monitoring plan (MP) in Attachment G.3. of the application is inadequate and
needs some revisions. Most of the wells proposed are injection performance monitoring wells
that are inside the injection zone,and may not be adequate to detect the movement of injection
fluids and/or injection process byproducts outside of the injection zone. However, if the wells
in the Corrective Action Monitoring Plan(CAMP)are included,this improves the monitoring
network to help comply with 15A NCAC 2C .0225(e)(2). Please add the following wells to
the MP: MW-35, MW-12,MW-13, MW-28, MW-36, RW-2, RW-3, RW-5, CMP-1, CMP-3,
CMP-4, and SW-3. Also, since MW-8 and MW-12 in the MP are constructed in regolith,
please install two additional wells in the same area installed deeper in transition zone and/or
bedrock(additional wells were proposed in the MP"if appropriate").
• Section 5.1.2 of the EAB IM Work Plan states"the wells to monitored may change with each
sampling event depending on the previous data and current operations." Once a monitoring
plan is approved, it is incorporated into the permit and may not change without a permit
modification.
• The additives Methanol (Section H.1.), potassium hydroxide (Section H.1.),
Hydrochloric/muriatic acid(EAB IM Work Plan pdf page 14),and Miracle Gro(Section H.S.)
are proposed for either injection or well maintenance. Upon initial preliminary review, these
compounds do not appear to have been previously approved by the NC DHHS for use in NC.
The DHHS will be contacted to confirm. If these additives are not approved, and you wish to
use them, the approval process will need to be accomplished. Information on this process is
on the Division of Water Resources(DWR)website at
https://deq.nc.gov/about/divisions/water-resources/water-quality-regional-
operations/groundwater-protection.
• What will be the source of the extracted groundwater that will be used to flush the pH buffer
and/or amendments described in Section H.S. of the application, and in the EAB IM Work
Plan Section 2? This is order to determine compliance with 15A NCAC 02L .0202 and 15A
NCAC 02C .0225(e)(5)(C).
In summary of the MP: (1)sample all of the wells listed in Section G3 of the application(including the
referenced 2 additional proposed wells)for the constituents and the frequency proposed until the permit
is rescinded, and (2) continue to conduct the monitoring that was required in the first version of the
permit issued April 18, 2014. Reporting will be submitted annually.
If you have any questions in regards to this additional information request, please contact Andrew
Moore in reply to this email or at(828) 296-4500 as I will be on vacation the next two weeks. Also,
please mail any corrected pages/maps to the application in same format and size for replacement. Send

Subject:WQ0036881 Murphy NC Permit
Michael,
I am a hydrogeologist working on the Murphy project for Northrop Grumman (for over 10 years) and
was asked to review the groundwater remediation permit modification that was recently issued for the
bioremediation project. All seems to be order, however, I do have a question regarding the Applicable
Boundaries. The current permit covering the reinjection of groundwater from the treatment system
contains the following language related to Applicable Boundaries.
i

#v
"Compliance and review boundaries as described in rules 15A NCAC 02L .0107 and .0108 have not
been incorporated into this permit on the basis that the site contaminated groundwater will be treated
to the groundwater quality standards specified in rule 15A NCAC 02L .0202 prior to injection and that
injection operations will not displace groundwater contamination into uncontaminated areas."
I assume that this existing permit condition remains in effect for the reinjection of treated
groundwater. It also seems to be appropriate for the bioremediation activities. However, the modified
permit for bioremediation contains what appears to be the standard language defining a Compliance
Boundary, Review Boundary, and possible remediation actions stemming from waste disposal. This
does not appear to be consistent with the bioremediation activities being permitted.
I would like to discuss this with you when you have the opportunity. Please let me know when we can
have a call to discuss.
Thanks

Please recall that the proposed remedial injection wells and air sparge wells vary from their respective 2C construction
standards.We determined that the proposed well construction met the conditions for a variance as described in 15A
NCAC 02C.0241(a)and that determination was summarized in a June 18, 2018, email to the applicants.The variance to
well construction may need to be incorporated into the permit per 15A NCAC 02C .0241(d).

• OK, I read the references to willingness to using the already approved additives instead of the proposed in
Comment 6. Good, Let's go that route.
• In regards to methanol, I don't see where we received the formal packet requesting review for this non-
microbial additive.

A list of approved well rehab/disinfectants is at the link below.

Hi Andy-
Thanks for your quick review and comments regarding our permit modification request. We have compiled
some questions/clarifications about your comments and also responded to some of the simple
questions. Once we receive your response to this email, we will compile a more formal response by letter that
should satisfy the Division of Water Resources (DWR).
Comment#1: Well construction details:The well construction details D and E provided on Figure 10 for the
top of grout and grout/seal type are a mistake,the details A and B provided on Figure 8 correctly show how
we want to construct the wells in regards to the grout type and depth. Our intent is to use a bentonite-
amended Portland cement grout mixed in the ratios and manner described on Figure 8 and set to the depths
as noted on Figure 8. All of these wells will be located in high traffic areas, so they all have to be finished with
flush-mounted well vaults, so the grout has to be terminated some distance below grade to allow connections
to the well and install the well vault. Our standard approach for a remedial injection well is to install a pitless
adapter at 3-feet below grade to protect the pipe and prevent water pipes from freezing inside the vault, so
terminating the grout at 4-feet below grade allows some working space above the grout to install the pitless
adapter. For the sparge well, we typically connect the sparge gas line to the well below grade and below the
inside of the well vault at 1.5-feet below grade to protect the connection and minimize the chance of breaking
the high pressure gas line connection to the well, so we show the grout placed to 3-feet below grade to allow
for this connection to be made, however, we can raise the grout level for the sparge wells to 2-feet below
grade and still have working space above it.
Comment#2:Well head piping and connections: As discussed in our response to comment#1,we prefer to
have connections to the well below grade and below the inside of the well vault to protect the pipe and
associated connections. We understand the concern and intent of the regulations in regards to surficial
contaminants entering the well, so we do completely seal the wells with threaded PVC fittings at the top, and
the side connections use compression 0-rings to create a liquid-tight seal on the pitless adapter(remedial
injection well) and the saddle fitting (sparge well). All of the fittings are considered liquid-tight fittings, and
the use of PVC well casing allows for these connections to seal the well completely once installed.
Comment#3: Grout seal for sparge wells: Detail E on Figure 10 when it refers to the top of bentonite hole-plug
is a mistake, detail B on Figure 8 shows our intended construction for the sparge wells; to bring the grout up to
3-feet below grade. Our reasoning for the depth to the top of grout for both remedial injection wells and
sparge wells was discussed in the previous responses. However, as noted previously, we will raise the depth to
the top of grout for the sparge wells to 2-feet below grade as this should still allow the side connection to the
well.
4

Comment#4: Sampling Locations: Northrop proposed installing additional wells near wells MW-12 and MW-
18 in the Interim Measures Plan and as shown on Figure 3 in the design drawings of the UIC permit
modification. We will clarify the text that these new wells are being proposed/sampled. In summary, we will
sample the wells listed in section G3 of permit modification plus the new wells near MW-8 and MW-12 and
continue with the existing monitoring plan (April 18, 2014 version).
Comment#5: We acknowledge that once the sampling plan is approved, it cannot be reduced. We may add
selected additional monitoring wells as needed.
Comment#6: Northrop Submitted Risk Assessment Evaluation of Groundwater or Soil Remediation Additives
Containing for Methanol addition on April 9, 2018. (cover letter attached). With regards to the other additives
mentioned in the comment letter:
Section H-1 summarizes that we expect to use 1) DAP (approved additive). Miracle grow is essentially
solubilized DAP. If the DWR prefers that we use DAP and not Miracle grow that is easy to do, 2) Section H1
states that may use sodium or potassium hydroxide. Those are both essentially the same (hydroxide base). If
the DWR prefers sodium hydroxide, we can use that, although potassium hydroxide is less reactive with clays
and is slightly preferable. 3) Muriatic acid/HCI is not an additive and is only used to clean the wells (as
needed). Once the cleaning is completed,the acid is pumped out. If the DWR prefers,we can use sulfuric
acid, which is an approved additive.
Comment#7:
No groundwater injection is proposed. The word groundwater is a typographical error and should be tap-
water

IV. ADDITIONAL REGIONAL STAFF REVIEW COMMENTS/ATTACHMENTS(If Needed)
Overall,the proposed monitoring network in the application is: (1)inadequate for the Enhanced Anaerobic
Bioremediation injections,(2)somewhat vague with regard to proposed additional monitoring wells, (3)
displays some minor inconsistency with the EAB IM Work Plan document provided with the application, (4)
and does not address/discuss the monitoring required as part of the active groundwater remediation system.
With regard to(1),the proposed monitoring plan in Attachment G.3. of the application predominately consists
of performance monitoring wells within the injection zone and may not be adequate to detect the movement of
injection fluids or injection process byproducts outside of the injection zone.However,there is an adequate
monitoring network if the wells in the Corrective Action Monitoring Plan(CAMP)are included. This includes
the following wells: MW-35,MW-12,MW-13,MW-28,MW-36,RW-2,RW-3,RW-5, CMP-1, CMP-3, CMP-
4,and SW-3.With regard to(2),MW-8 and MW-12 are included in the monitoring plan with the application.
However,both of these wells are constructed in regolith. There are several references to constructing additional
transition zone and bedrock wells at the locations of MW-8 and MW-12"if appropriate". See Figure 3 in
application. We need clarification on whether these wells will,or will not,be constructed. With regard to(3),
Section 5.1.2 of the EAB IM Work Plan states"the wells to monitored may change with each sampling event
depending on the previous data and current operations." We need to clarify that once a monitoring plan is
approved,it is incorporated into the permit and may not change without a permit modification. With regard to
(4),the application indicates the currently operating groundwater treatment injection system will continue to
operate,however,there is no discussion of the monitoring associated with that portion of the system. Overall,
the Division needs to make clear to the applicant,that they will be required to sample all of the wells listed in
Section G3 of the application for the constituents and the frequency proposed until the permit is rescinded and
the data must be submitted annually.In addition,we need to make clear that the applicant shall continue to
conduct the monitoring that was required in the first version of the permit.Note that this monitoring includes
the additional CAMP wells noted above.

Fl
L 321 1) Pressure transmitter PT-100 will track influent compressed air pressure and shut
down operation of the oxygen sparging system if the compressed oir pressure
drops below 90 psi. This is to allow for the plant to take priority usage of the
CONNECT TO 1'0 compressed air generoted and only use compressed air when the facility has
SPARGE WELL excess.
2) Pressure transmitter PT-200 will track generated oxygen gas pressure and shut
down operation of the oxygen sparging system if the compressed oxygen pressure
drops below 35 psi. This will allow the system to generate more high purity
oxygen gas and catch up with oxygen spurge injection rate.
3) Solenoid valves SV-310 and SV-320 will control flow to the two sets of sparge
wells, cycling between the two groups one at a time, with each operating for an
operator-selected amount of time. This will help distribute oxygen to the areas
that need it most.
