Subject: Coal Combustion Residuals (CCR) Visual Removal Verification Report
Dan River Steam Station
Rockingham County, North Carolina
Dear Ms. Martin:
SynTerra Corp. (SynTerra) concludes that visual CCR removal verification has been
satisfied in general accordance with the "Excavation Soil Sampling Plan, Dan River
Steam Station Ash Basin System," Rev. 2, dated December 2018 (Attachment 1) and in
accordance with the soil closure guidelines that Duke Energy Carolinas received from
the "CCR Surface Impoundment Closure Guidelines for Protection of Groundwater"
received via cover letter from the North Carolina Department of Environmental
Quality (NCDEQ) dated November 4, 2016. This report documents the completion of
ash removal from the primary and secondary ash basins, which was required by the
North Carolina Coal Ash Management Act of 2014.
Background
The Dan River Steam Station (Dan River, the Site) and the ash basins are depicted in
Figure 1. The ash basins were constructed in three phases, beginning with what is
presently referred to as the primary ash basin. The primary ash basin is impounded by
a dam along the Dan River, which was constructed with borrowed material from the
ash basin footprint. In 1968 and 1969, the basin was expanded to include a secondary
basin. An earthen dike was built on top of the ash to separate the primary and
secondary ash basins in 1976. The estimated surface area of the ash basins is
approximately 58 acres. The original estimate of ash contained within the ash basins
was 1,336,138 cubic yards. A total of 1,766,153 cubic yards of material was disposed of
from the ash basins, which is 440,015 cubic yards greater than the original, estimated
quantity of ash. Ash was moved from the ash basins to the following locations:
Beneficial Reuse: 131,601 tons
On -Site CCP Landfill: 1,834,968 tons
Off -Site Landfill: 28,817 tons

Field Evaluation
Field evaluation consisted of conducting visual inspection of collected soil samples.
Soil sampling on a 100-foot by 100-foot grid (Figure 2), following the removal of ash,
was conducted and the collected samples were analyzed for the quantity of remaining
ash via polarized light microscopy (PLM). Photographs of boring locations and
samples taken at each location are provided in the attached photo log (Attachment 2).
A summary of field documentation for locations within the basins is provided as
Table 2.
Visual CCR Removal Verification Results
CCR removal was evaluated based on three criteria:
1. Comparison of estimated bottom of CCR grades to post-CCR removal grades;
2. Visual observation; and
3. PLM analysis.
Comparison of estimated bottom of CCR to post-CCR removal grades
The elevation of the bottom of ash basin was estimated to be 500 feet. However,
limited historical data was available to estimate the bottom of ash elevation, and this
method is determined to be unreliable for verifying ash removal. Relevant data is
presented in Table 1.
Visual Observation
Visual observation to confirm the removal of CCR and estimate the remaining
percentage of ash was performed on a 100-foot by 100-foot grid (Figure 2). Photos of
visual observation locations are provided in the attached photo log (Attachment 2).
PLM Evaluation
Sampling depths of 0 - 6 inches below ground surface (bgs) and 24 to 30 inches (bgs)
and visual soil classifications for PLM evaluation were conducted on the 100-foot by
100-foot grid shown in Figure 2. Sampling was performed using a hand auger or
Direct Push Drill Rig (Geoprobe). Sample results and sample collection method refusal
at depths less than 24 inches that prevented sampling are noted in Table 2 for the ash
basins. Refusal was noted when substrate that was too hard for the hand auger or
Geoprobe to penetrate was encountered at a depth less than the required sampling
interval. Sample locations that were offset from the originally proposed grid location
are noted in Table 2.
PLM evaluations were performed by RJ Lee Group and the results are included as
Attachment 3. All results indicated an ash percentage less than the maximum
allowable proportion of 50 percent as described in the Excavation Soil Sampling Plan
(Attachment 1). Within the ash basin, the maximum percent of ash identified by PLM
was 17 percent.

Conclusion
CCR removal verification has been completed in accordance with the Excavation Soil
Sampling Plan, Dan River Steam Station Ash Basin System Rev.2, December 2018 and
in accordance with the soil closure guidelines that Duke Energy Carolinas received
from the North Carolina Department of Environmental Quality (NCDEQ) on
November 4, 2016.

Exhibit A: Excavation Soil Sampling Plan

Statement of Purpose
Duke Energy Carolinas, LLC (Duke Energy or the Company) is required by Part II, Section
3(b) of the Coal Ash Management Act of 2014 (Session Law 2014-122) (Coal Ash Act or
Act) to close, in accordance with Part II, Section 3(c), the coal combustion residuals
(CCR) surface impoundments located at the Dan River Combined Cycle Plant (Dan River
or Plant), National Pollutant Discharge Elimination System (NPDES) Permit No.
NC0003468, in Rockingham County as soon as practicable, but not later than August 1,
2019.
This Coal Ash Excavation Plan (Plan) represents activities to satisfy the requirements
outlined in Part II, Sections 3(b) and 3(c), Subparagraphs 1 and 2 of the Act and the
requests set forth in the North Carolina Department of Environmental Quality's (NCDEQ)
August 13, 2014 letter titled "Request for Coal Ash Excavation Plans for Asheville Steam
Station Electric Generating Plant, Dan River Combined Cycle Station, Riverbend Steam
Station, L.V. Sutton Electric Plant" (NCDEQ Letter). The NCDEQ Letter specifically
requests that the Plan include 1) soil and sediment erosion control measures, 2)
dewatering, and 3) the proposed location(s) of the removed ash. These requirements are
found in this updated Plan.
This is a revision of the Coal Ash Excavation Plan updated December 1, 2017, which
covered the subsequent phase of ash basin excavation activities, including basin
dewatering, site preparation, ash basin preparation, and ash removal from the basins at
Dan River. The Plan has been updated and submitted to NCDEQ annually; however,
due to the anticipated completion of ash basin excavation activities by the applicable
CAMA deadline, no further updates will be made to the Plan.
The Plan covers some of the work required by Part II, Sections 3(b) and 3(c) of the Coal
Ash Act. The Act requires the closure of the ash basins as soon as practicable, but no
later than August 1, 2019. However, the Act contains no requirement for the submittal of
an excavation plan of the kind presented here. Thus, while the formulation, submittal,
and review of this Plan will assist in Duke Energy's work to close the ash basins, its
ultimate approval is an action not specifically required by statutory, regulatory, or other
applicable authority.
The scope of work in excavating the ash basins has been determined by applicable laws,
rules, permits, and approvals that control the activities to be performed under the Plan.
There are several external and internal factors that could potentially affect the precise
scope of the work to be performed under the Plan. As a consequence, neither the
submittal of this Plan nor its acknowledgement by NCDEQ should be taken as requiring
actions different from such applicable requirements. Duke Energy submits this Plan to
NCDEQ based on the understanding that it may be necessary to take actions that deviate
from the Plan in the future, and the Company reserves the right to make such changes.
1: Dan River

General Facility Description
The Dan River Steam Station is located in Rockingham County near Eden, NC. The Plant
operated from 1949 until retirement of the coal-fired units in 2012. Upon retirement of the
coal-fired units, a new 620 MW gas -fired unit began operations.
The Primary Ash Basin was constructed in 1956, with an embankment crest elevation of
523.5 feet mean sea level (msl). In 1968, the basin embankment crests were raised to
elevation 530 feet msl and extended in length approximately 1,200 feet east along the
Dan River. An intermediate dike was constructed in 1976, resulting in two basins, with
the Primary Ash Basin dam crest being raised to elevation 540 feet msl. The east side of
the basin was designated the Secondary Ash Basin. The Primary Ash Basin was
periodically dredged and the material dry -stacked on higher terrain north of the basins
(referred to as dry ash stacks). The dam numbers for the ash basins are (ROCKI-237)
and (ROCKI-238.) The dry ash stacks have been capped with soil.
Duke Energy's Coal Combustion Residuals Removal Verification Procedure (Removal
Verification Procedure) will be used to verify that primary source ash has been removed
from the basin. Subsequent to removal of the ash pursuant to the Removal Verification
Procedure, Duke Energy will implement its Excavation Soil Sampling Plan (ESSP), which
was developed for the purpose of meeting the applicable performance standard.
Although not required under CAMA, in November 2016, NCDEQ sent Coal Combustion
Residuals Surface Impoundment Closure Guidelines for Protection of Groundwater to
Duke Energy instructing the Company to submit the ESSP to NCDEQ as part of the site's
excavation plan. In accordance with this directive, a copy of the ESSP is attached as
Exhibit "A" to this Plan.
Primary Ash Basin
The Primary Ash Basin at Dan River consists of a composite dam made up of local borrow
materials, including silty sands and sandy silts with some clay. Portions of the dam may
have been built on, or contain, ash materials. The eastern face of the embankment is
armored with rock up to elevation 512 feet msl. A rock fill berm was constructed alongside
the river, up to elevation 503 feet msl. An intermediate bench was constructed at
approximate elevation of 530 feet msl. The primary basin has an approximate footprint
of 39 acres with a surface water area of 18 acres. The Primary Ash Basin received sluiced
ash from pipes in the southwest corner and outlets into the Secondary Ash Basin through
a decant structure located near the northeast corner of the Primary Ash Basin. Initially,
the Primary Ash Basin contained approximately 1,215,000 tons of CCR material. In
September 2018, the CCR inventory of the Primary Basin was increased by 552,000 tons
due to quantifying CCR material under vertical expansion embankment soil, incorporating
revised bottom of ash floor grades, and including estimated soil waste.
2: Dan River

Intermediate Dike
(Separates the Primary Ash Basin and the Secondary Ash Basin)
The intermediate dike was constructed in 1976, bisecting the basin into Primary and
Secondary Ash Basins. The dike was constructed on existing ash deposits, with an upper
crest elevation of 540 feet msl adjacent to the Primary Ash Basin and a lower crest
elevation of 530 feet msl adjacent to the Secondary Ash Basin. The dike has a surface
road at the 540 feet msl level. It has a vegetated slope adjacent to the road, which
extends to a 530 feet msl elevation shelf adjacent to the Secondary Ash Basin. A rock
buttress was constructed below the elevation 530 feet msl crest. The width of the
intermediate dike is approximately 100 feet.
aFCliVIlual y r,ali opal,.
The Secondary Ash Basin embankments, including the intermediate dike forming the
southwest boundary, have a crest elevation of 530 feet msl and are constructed of the
same local materials as the Primary Ash Basin. The eastern face of the embankment is
armored with rock up to elevation 512 feet msl. A rock fill berm was constructed alongside
the river, up to elevation 503 feet msl. The basin receives decanted flow from the Primary
Ash Basin in the northwestern corner, and flows exit the basin through a decant structure
near the southeastern corner. Flow from the Secondary Ash Basin is regulated by
NPDES Permit No. NC 0003468. The pool level is controlled by the decant riser using
concrete stop -logs and conveys to the outlet through a 36-inch diameter reinforced
concrete pipe constructed through the embankment dike. Initially, the Secondary Ash
Basin contained approximately 390,000 tons of CCR material.
Ash Stack
The dry ash stacks are located to the north of the Primary and Secondary Ash Basins.
These ash stacks consist of CCR material dredged from the Primary Ash Basin. Initially,
Ash Stack 1 and Ash Stack 2 contained approximately 950,000 tons and 415,000 tons of
CCR material, respectively. For the purposes of stormwater management, the ash stacks
are located within the ash basin system. Stormwater run-off from the ash stacks is
contained within the ash basin system and flows to the Secondary Ash Basin. The
excavation of all CCR from Ash Stack 1 was completed on July 27, 2017.
11. Project Charter
Dewatering of the ash basins and the removal of ash from the site will be performed in
project phases. As of November 1, 2018, approximately 2.67 million tons of ash have
been excavated. Approximately 1.2 million tons were transported to an off -site landfill.
Approximately 106,560 tons were sent to the Roanoke Cement Company for beneficial
use and the remainder to an on -site landfill. This project has completed Phase I and is
now implementing Phase II.

The Dan River NPDES wastewater permit was issued and became effective on
December 1, 2016. The removal of bulk free water of the Secondary Basin was
completed when the basin water level was lowered to elevation 515 feet msl in 2016.
Interstitial dewatering commenced in 2018 to support excavation in the Secondary and
Primary Basins and is on -going. All leachate and contact stormwater wastewater
treatment will be performed by the City of Eden's Publicly Owned Treatment Works
(POTW) in accordance with the Industrial User Pre-treatment Permit issued to Duke
Energy by the City of Eden. To provide additional wastewater treatment capability, an
on -site treatment system is being installed, which will send treated water to the discharge
point of Outfall 002. The Secondary Basin riser structure and the pipe leading to Outfall
002 was plugged with grout on September 6, 2018.
The excavation of Ash Stack 1 began on October 13, 2015, following acknowledgement
of this Plan by NCDEQ and the receipt of final permits. Phase I was completed on March
23, 2017. Phase II will include completion of the on -site landfill and excavation of the
basins to the on -site landfill. Construction of an on -site landfill began on October 31,
2016, following receipt of the Landfill Permit -to -Construct by NCDEQ.
In accordance with the project plan, during Phase I, the Company removed ash to an off -
site location while simultaneously developing an on -site landfill, which was needed in
order to meet the closure requirements mandated in the Coal Ash Act. The Company
received a Permit -to -Operate (PTO) for the first landfill cell on May 30, 2017, and promptly
began transporting ash to the on -site landfill. The PTO for the second landfill cell was

The Erosion and Sediment Control (E&SC) Plan for the excavation of the Ash Stack and
related site activities have been approved. The approval of this plan by NCDEQ meets
the requirement outlined in the referenced NCDEQ Letter. Modifications from E&SC
plans for subsequent phase(s) will be approved by NCDEQ prior to installation and
initiation of subsequent phase work. The approved contractor will install the E&SC
measures indicated in the plan. All control measures will be maintained throughout the
project in accordance with the E&SC plans. When possible, portions of the E&SC plan
will be closed out at the approval of NCDEQ as areas become stabilized.
VI. Dewatering Plan
The Dan River ash basins are being dewatered to facilitate the removal of ash and to
mitigate risk. Interstitial dewatering of the Primary Ash Basin commenced in March 2018.
Interstitial dewatering of the Secondary Ash Basin commenced in June 2018. Leachate
from the onsite landfill, interstitial waste water, and contact stormwater are being treated
by the City of Eden's Publicly Owned Treatment Works (POTW) in accordance with the
Industrial User Pre-treatment Permit issued to Duke Energy by the City of Eden. In
addition, and to provide additional treatment capacity beyond what the City of Eden could
accommodate, that facility installed an on -site wastewater treatment system in Q3 2018
to treat interstitial wastewater for discharge to Outfall 002 in compliance with the facility's
NPDES Wastewater Permit.
6: Dan River

Location(s) for Removed Ash
Ash removed from the site will be transported by the contractor to permitted facilities. The
ash disposal location(s) will be managed and maintained to ensure environmental
compliance with all applicable rules and regulations.
Disposal Sites
The Maplewood Landfill and the on -site landfill at Dan River have been identified as the
primary disposal locations.
Maplewood Landfill
The Maple Landfill is located near Jetersville, VA and is where 1.2 million tons of ash
where shipped by rail during Phase I. The final rail shipment of ash to the Maplewood
Landfill from Dan River occurred on March 23, 2017.
Dan River On -site Landfill
Transportation of ash to the on -site landfill began on May 31, 2017. The project team
utilized lessons learned from Phase I in developing and constructing the on -site landfill,
which provides the improvements below:
• Provide a reliable, long-term, cost-effective solution for ash designated for
removal
• Support development of a diverse supplier program to drive innovation and
competition
• Establish performance baselines and a system to optimize excavation,
transportation, and disposal of ash
Transportation Plan
Ash is currently being transported from the basins via off -road articulated dump truck to
the on -site landfill. Truck loading operations will be conducted with a crew working
typically 12 hours per day, five to six days per week. Ash transportation to Roanoke
Cement Company for beneficiation is by on -road truck. Transportation off -site will be
conducted by approved transporters and will meet Department of Transportation (DOT)
and other applicable federal, state, and local regulations.
Environmental and Dam Safety Permitting Plan
Excavation of ash creates potential for stormwater impacts. The facility holds an
approved E&SC plan and associated Construction Stormwater Permit approval for ash
stack removal. Also, NCDEQ indicated that an NPDES Industrial Stormwater Permit is
required to excavate ash. The Company has received the NPDES Industrial Stormwater
Permit to support ash removal at the site. Pursuant to the requirements of the NPDES
Industrial Stormwater Permit, a stormwater pollution prevention plan (SPPP)
7: Dan River

incorporating best management practices has been created and is currently being
implemented. Future modifications to the permit/plan will be managed as necessary. On
October 27, 2016, Duke Energy received a modified NPDES Wastewater Permit, which
included provisions for dewatering activities.
The area between Ash Stack 1 and Ash Stack 2 was determined to be a jurisdictional
wetland and an Individual Permit (IP) will be required to remediate this area and complete
stormwater diversion prior to basin closure. Wetlands/stream impacts related to the rail
improvements were managed through the United States Army Corps of Engineers
(ACOE) with particular attention paid to the difference between jurisdictional
wetlands/streams under Section 404 and those arising from Section 401 waters. The
Company received approvals from ACOE and NCDEQ for wetlands/stream impacts
related to the rail. The company received approvals from ACOE and NCDEQ for
wetlands/stream impacts related to stormwater diversion in the fourth quarter of 2017.
Dan River ash is a non -hazardous material.
Subsequent phase(s) will include dewatering and continued excavation and removal of
ash from the Primary and Secondary Ash Basins. Subsequent phase(s) also include the
continued construction of the on -site landfill.
In order to facilitate on -site landfill construction and operation, NCDEQ's Solid Waste
Section issued a Landfill Permit -to -Construct on October 27, 2016. Following
construction of each cell of the on -site landfill, Construction Quality Assurance Reports
were submitted to obtain the corresponding PTO. NCDEQ's Solid Waste Section issued
a Landfill PTO for Cell 1 on May 30, 2017, a Landfill PTO for Cell 2 on October 2, 2017,
and a Landfill PTO for Cell 3 on April 18, 2018.
Dam Decommissioning Plan Sequence `A' was approved by NCDEQ Dam Safety on
February 20, 2018. Dam Decommissions Plan Sequence `B' was approved by NCDEQ
Dam Safety on July 16, 2018. Decommissioning Plan Sequence `C' will be submitted to
NCDEQ Dam Safety no later than Q1 2019. Any impacted wells or piezometers will be
properly abandoned in accordance with NCDEQ requirements. Fugitive dust will be
managed to mitigate impacts to neighboring areas.
Other than the agreement with City of Eden regarding development of the on -site landfill,
there are no additional site -specific or local requirements identified.

Building 7405, MG30A2
Huntersville, NC 28078
RE: Duke Energy Project — J19040597
RJ Lee Group Project Number AOH1053717-0
Dear Mr. Robinson,
The RJ Lee Group, Inc. Monroeville laboratory received 84 samples on April 19, 2019 associated with
Duke Energy job number J19040597. The samples were logged into RJ Lee Group project number
AOH1053717-0 and assigned RJLG sample numbers as indicated in Appendix A.
Upon verification, one of the sample jars had arrived with a cracked lid. The material was able to be
transferred to another jar for analysis. The cooler was received in good condition with all custody seals
in place and intact. Attached in Appendix A is the signed sample receipt confirmation form, COC, and
sample receipt check list.
These results are submitted pursuant to RJ Lee Group's current terms and conditions of sale, including
the company's standard warranty and limitation of liability provisions. No responsibility or liability is
assumed for the manner in which the results are used or interpreted. Unless notified to return the
samples covered in this report, RJ Lee Group will store them for a period of ninety (90) days before
discarding.
Should you have any questions regarding this information, please do not hesitate to contact us.
Sincerely,
Bryan R. Bandli, PhD

An e-mail was sent to Erin Kinsey on 04-24-19. There were 63 samples listed on the COC and we received a total of 84 samples.
A list of the samples not listed on the COC was included. Erin confirmed that the additional samples are all part of the same job.
I requested a revised COC. On 04-25-19, two additonal pages were sent to be added to the original COC.
One of the sample jars arrived cracked. We were able to transfer sample to another jar.

Hi Erin,
|fthese are tobeincluded onthe same job, | will need arevised CDC. Uthey are aseparate job, | will need aCO[for
those. If you saw the list, one of the jars was cracked, but we may be able to transfer to another jar for drying. Due to
the number of samples received and the fact that they still need to be dried, crushed and analyzed, the results will not
be available for 5-days. |fthey are done sooner, | will certainly e-mail the results.
Have aGreat Day!

Looks like we omitted a chain, I apologize for that. Those samples should have been included and should be analyzed for

Good Morning Erin,
I was out of the office on Friday, when your samples arrived. I am forwarding an e-mail to you that was
sent to Duke regarding those samples by my co-worker. It looks like there are samples that were
received that were not listed on the COC. She has not heard back from anyone and has not been able to
log in the samples. Since I am back in the office today, I thought I would check with you. Please advise.

. The method reporting level is 1 % and anything <1 % is considered a not -detected.
Quartz — Angular anisotropic particulate with low relief.
Feldspar — Angular to blocky anisotropic particulate, low to moderate relief, biaxial, can have polysynthetic twinning.
Clay — Sheet silicates with polycrystalline or display non -uniform extinction with low to moderate relief, and zero to low birefringence. Clay also refers to particles that are less than 2.0 microns.
Opaques — Opaque is a generic term for a particle that does not transmit light. Opaque minerals are distinguished from opaque bottom ash based on morphology of fracture.
Fly Ash — Isotropic to opaque spheres, agglomeration of spheres, and angular ash particles.
Organic Particulate — Pollen, plant and insect matter, and carbonaceous matter.
Carbonates — High birefringent, can be rhombohedral, with high relief.
Diatoms — Silica rich isotropic particles with various morphologies.
Mica — Sheet silicate with moderate to high relief and low birefringence, mono -crystalline, and normal extinction.
Miscellaneous Silicate — Isotropic and anisotropic silicates, with low to high relief, identification unsure and beyond the scope of the method to identify.
Amphibole — Elongated anisotropic particulate with moderate to high relief.
Coal — Irregular to angular particles with moderate opacity, edges and thin particles are reddish brown in color.
<1 % Fly Ash — Fly Ash observed, none counted.
ND — No Fly Ash detected.

* Any reproduction of this document must include the entire document in order for the report to be valid.
• This report may not be used to claim product endorsement by NVLAP Lab Code 101208-0 or any agency of the U.S. Government.
• Sample(s) for this project were analyzed at our: Monroeville, PA (AIHA # 100364, NVLAP # 101208-0, NY ELAP # 10884) facility.
• If RJ Lee Group, Inc. did not collect the samples analyzed, the verifiability of the laboratory's results is limited to the reported values.
• For the purposes of this method, Fly Ash is defined as any particle consistent with Coal Ash.
. The method reporting level is 1 % and anything <1 % is considered a not -detected.
Quartz — Angular anisotropic particulate with low relief.
Feldspar — Angular to blocky anisotropic particulate, low to moderate relief, biaxial, can have polysynthetic twinning.
Clay — Sheet silicates with polycrystalline or display non -uniform extinction with low to moderate relief, and zero to low birefringence. Clay also refers to particles that are less than 2.0 microns.
Opaques — Opaque is a generic term for a particle that does not transmit light. Opaque minerals are distinguished from opaque bottom ash based on morphology of fracture.
Fly Ash — Isotropic to opaque spheres, agglomeration of spheres, and angular ash particles.
Organic Particulate — Pollen, plant and insect matter, and carbonaceous matter.
Carbonates — High birefringent, can be rhombohedral, with high relief.
Diatoms — Silica rich isotropic particles with various morphologies.
Mica — Sheet silicate with moderate to high relief and low birefringence, mono -crystalline, and normal extinction.
Miscellaneous Silicate — Isotropic and anisotropic silicates, with low to high relief, identification unsure and beyond the scope of the method to identify.
Amphibole — Elongated anisotropic particulate with moderate to high relief.
Coal — Irregular to angular particles with moderate opacity, edges and thin particles are reddish brown in color.
<1 % Fly Ash — Fly Ash observed, none counted.
ND — No Fly Ash detected.

* This test report relates to the items tested.
* Any reproduction of this document must include the entire document in order for the report to be valid.
• This report may not be used to claim product endorsement by NVLAP Lab Code 101208-0 or any agency of the U.S. Government.
• Sample(s) for this project were analyzed at our: Monroeville, PA (AIHA # 100364, NVLAP # 101208-0, NY ELAP # 10884) facility.
• If RJ Lee Group, Inc. did not collect the samples analyzed, the verifiability of the laboratory's results is limited to the reported values.
• For the purposes of this method, Fly Ash is defined as any particle consistent with Coal Ash.
. The method reporting level is 1 % and anything <1 % is considered a not -detected.
Quartz — Angular anisotropic particulate with low relief.
Feldspar — Angular to blocky anisotropic particulate, low to moderate relief, biaxial, can have polysynthetic twinning.
Clay — Sheet silicates with polycrystalline or display non -uniform extinction with low to moderate relief, and zero to low birefringence. Clay also refers to particles that are less than 2.0 microns.
Opaques — Opaque is a generic term for a particle that does not transmit light. Opaque minerals are distinguished from opaque bottom ash based on morphology of fracture.
Fly Ash — Isotropic to opaque spheres, agglomeration of spheres, and angular ash particles.
Organic Particulate — Pollen, plant and insect matter, and carbonaceous matter.
Carbonates — High birefringent, can be rhombohedral, with high relief.
Diatoms — Silica rich isotropic particles with various morphologies.
Mica — Sheet silicate with moderate to high relief and low birefringence, mono -crystalline, and normal extinction.
Miscellaneous Silicate — Isotropic and anisotropic silicates, with low to high relief, identification unsure and beyond the scope of the method to identify.
Amphibole — Elongated anisotropic particulate with moderate to high relief.
Coal — Irregular to angular particles with moderate opacity, edges and thin particles are reddish brown in color.
<1 % Fly Ash — Fly Ash observed, none counted.
ND — No Fly Ash detected.

* This test report relates to the items tested.
* Any reproduction of this document must include the entire document in order for the report to be valid.
• This report may not be used to claim product endorsement by NVLAP Lab Code 101208-0 or any agency of the U.S. Government.
• Sample(s) for this project were analyzed at our: Monroeville, PA (AIHA # 100364, NVLAP # 101208-0, NY ELAP # 10884) facility.
• If RJ Lee Group, Inc. did not collect the samples analyzed, the verifiability of the laboratory's results is limited to the reported values.
• For the purposes of this method, Fly Ash is defined as any particle consistent with Coal Ash.
. The method reporting level is 1 % and anything <1 % is considered a not -detected.
Quartz — Angular anisotropic particulate with low relief.
Feldspar — Angular to blocky anisotropic particulate, low to moderate relief, biaxial, can have polysynthetic twinning.
Clay — Sheet silicates with polycrystalline or display non -uniform extinction with low to moderate relief, and zero to low birefringence. Clay also refers to particles that are less than 2.0 microns.
Opaques — Opaque is a generic term for a particle that does not transmit light. Opaque minerals are distinguished from opaque bottom ash based on morphology of fracture.
Fly Ash — Isotropic to opaque spheres, agglomeration of spheres, and angular ash particles.
Organic Particulate — Pollen, plant and insect matter, and carbonaceous matter.
Carbonates — High birefringent, can be rhombohedral, with high relief.
Diatoms — Silica rich isotropic particles with various morphologies.
Mica — Sheet silicate with moderate to high relief and low birefringence, mono -crystalline, and normal extinction.
Miscellaneous Silicate — Isotropic and anisotropic silicates, with low to high relief, identification unsure and beyond the scope of the method to identify.
Amphibole — Elongated anisotropic particulate with moderate to high relief.
Coal — Irregular to angular particles with moderate opacity, edges and thin particles are reddish brown in color.
<1 % Fly Ash — Fly Ash observed, none counted.
ND — No Fly Ash detected.

• This report may not be used to claim product endorsement by NVLAP Lab Code 101208-0 or any agency of the U.S. Government.
• Sample(s) for this project were analyzed at our: Monroeville, PA (AIHA # 100364, NVLAP # 101208-0, NY ELAP # 10884) facility.
• If RJ Lee Group, Inc. did not collect the samples analyzed, the verifiability of the laboratory's results is limited to the reported values.
• For the purposes of this method, Fly Ash is defined as any particle consistent with Coal Ash.
. The method reporting level is 1 % and anything <1 % is considered a not -detected.
Quartz — Angular anisotropic particulate with low relief.
Feldspar — Angular to blocky anisotropic particulate, low to moderate relief, biaxial, can have polysynthetic twinning.
Clay — Sheet silicates with polycrystalline or display non -uniform extinction with low to moderate relief, and zero to low birefringence. Clay also refers to particles that are less than 2.0 microns.
Opaques — Opaque is a generic term for a particle that does not transmit light. Opaque minerals are distinguished from opaque bottom ash based on morphology of fracture.
Fly Ash — Isotropic to opaque spheres, agglomeration of spheres, and angular ash particles.
Organic Particulate — Pollen, plant and insect matter, and carbonaceous matter.
Carbonates — High birefringent, can be rhombohedral, with high relief.
Diatoms — Silica rich isotropic particles with various morphologies.
Mica — Sheet silicate with moderate to high relief and low birefringence, mono -crystalline, and normal extinction.
Miscellaneous Silicate — Isotropic and anisotropic silicates, with low to high relief, identification unsure and beyond the scope of the method to identify.
Amphibole — Elongated anisotropic particulate with moderate to high relief.
Coal — Irregular to angular particles with moderate opacity, edges and thin particles are reddish brown in color.
<1 % Fly Ash — Fly Ash observed, none counted.
ND — No Fly Ash detected.

• This report may not be used to claim product endorsement by NVLAP Lab Code 101208-0 or any agency of the U.S. Government.
• Sample(s) for this project were analyzed at our: Monroeville, PA (AIHA # 100364, NVLAP # 101208-0, NY ELAP # 10884) facility.
• If RJ Lee Group, Inc. did not collect the samples analyzed, the verifiability of the laboratory's results is limited to the reported values.
• For the purposes of this method, Fly Ash is defined as any particle consistent with Coal Ash.
. The method reporting level is 1 % and anything <1 % is considered a not -detected.
Quartz — Angular anisotropic particulate with low relief.
Feldspar — Angular to blocky anisotropic particulate, low to moderate relief, biaxial, can have polysynthetic twinning.
Clay — Sheet silicates with polycrystalline or display non -uniform extinction with low to moderate relief, and zero to low birefringence. Clay also refers to particles that are less than 2.0 microns.
Opaques — Opaque is a generic term for a particle that does not transmit light. Opaque minerals are distinguished from opaque bottom ash based on morphology of fracture.
Fly Ash — Isotropic to opaque spheres, agglomeration of spheres, and angular ash particles.
Organic Particulate — Pollen, plant and insect matter, and carbonaceous matter.
Carbonates — High birefringent, can be rhombohedral, with high relief.
Diatoms — Silica rich isotropic particles with various morphologies.
Mica — Sheet silicate with moderate to high relief and low birefringence, mono -crystalline, and normal extinction.
Miscellaneous Silicate — Isotropic and anisotropic silicates, with low to high relief, identification unsure and beyond the scope of the method to identify.
Amphibole — Elongated anisotropic particulate with moderate to high relief.
Coal — Irregular to angular particles with moderate opacity, edges and thin particles are reddish brown in color.
<1 % Fly Ash — Fly Ash observed, none counted.
ND — No Fly Ash detected.

* This test report relates to the items tested.
* Any reproduction of this document must include the entire document in order for the report to be valid.
• This report may not be used to claim product endorsement by NVLAP Lab Code 101208-0 or any agency of the U.S. Government.
• Sample(s) for this project were analyzed at our: Monroeville, PA (AIHA # 100364, NVLAP # 101208-0, NY ELAP # 10884) facility.
• If RJ Lee Group, Inc. did not collect the samples analyzed, the verifiability of the laboratory's results is limited to the reported values.
• For the purposes of this method, Fly Ash is defined as any particle consistent with Coal Ash.
. The method reporting level is 1 % and anything <1 % is considered a not -detected.
Quartz — Angular anisotropic particulate with low relief.
Feldspar — Angular to blocky anisotropic particulate, low to moderate relief, biaxial, can have polysynthetic twinning.
Clay — Sheet silicates with polycrystalline or display non -uniform extinction with low to moderate relief, and zero to low birefringence. Clay also refers to particles that are less than 2.0 microns.
Opaques — Opaque is a generic term for a particle that does not transmit light. Opaque minerals are distinguished from opaque bottom ash based on morphology of fracture.
Fly Ash — Isotropic to opaque spheres, agglomeration of spheres, and angular ash particles.
Organic Particulate — Pollen, plant and insect matter, and carbonaceous matter.
Carbonates — High birefringent, can be rhombohedral, with high relief.
Diatoms — Silica rich isotropic particles with various morphologies.
Mica — Sheet silicate with moderate to high relief and low birefringence, mono -crystalline, and normal extinction.
Miscellaneous Silicate — Isotropic and anisotropic silicates, with low to high relief, identification unsure and beyond the scope of the method to identify.
Amphibole — Elongated anisotropic particulate with moderate to high relief.
Coal — Irregular to angular particles with moderate opacity, edges and thin particles are reddish brown in color.
<1 % Fly Ash — Fly Ash observed, none counted.
ND — No Fly Ash detected.

• This report may not be used to claim product endorsement by NVLAP Lab Code 101208-0 or any agency of the U.S. Government.
• Sample(s) for this project were analyzed at our: Monroeville, PA (AIHA # 100364, NVLAP # 101208-0, NY ELAP # 10884) facility.
• If RJ Lee Group, Inc. did not collect the samples analyzed, the verifiability of the laboratory's results is limited to the reported values.
• For the purposes of this method, Fly Ash is defined as any particle consistent with Coal Ash.
. The method reporting level is 1 % and anything <1 % is considered a not -detected.
Quartz — Angular anisotropic particulate with low relief.
Feldspar — Angular to blocky anisotropic particulate, low to moderate relief, biaxial, can have polysynthetic twinning.
Clay — Sheet silicates with polycrystalline or display non -uniform extinction with low to moderate relief, and zero to low birefringence. Clay also refers to particles that are less than 2.0 microns.
Opaques — Opaque is a generic term for a particle that does not transmit light. Opaque minerals are distinguished from opaque bottom ash based on morphology of fracture.
Fly Ash — Isotropic to opaque spheres, agglomeration of spheres, and angular ash particles.
Organic Particulate — Pollen, plant and insect matter, and carbonaceous matter.
Carbonates — High birefringent, can be rhombohedral, with high relief.
Diatoms — Silica rich isotropic particles with various morphologies.
Mica — Sheet silicate with moderate to high relief and low birefringence, mono -crystalline, and normal extinction.
Miscellaneous Silicate — Isotropic and anisotropic silicates, with low to high relief, identification unsure and beyond the scope of the method to identify.
Amphibole — Elongated anisotropic particulate with moderate to high relief.
Coal — Irregular to angular particles with moderate opacity, edges and thin particles are reddish brown in color.
<1 % Fly Ash — Fly Ash observed, none counted.
ND — No Fly Ash detected.

• This report may not be used to claim product endorsement by NVLAP Lab Code 101208-0 or any agency of the U.S. Government.
• Sample(s) for this project were analyzed at our: Monroeville, PA (AIHA # 100364, NVLAP # 101208-0, NY ELAP # 10884) facility.
• If RJ Lee Group, Inc. did not collect the samples analyzed, the verifiability of the laboratory's results is limited to the reported values.
• For the purposes of this method, Fly Ash is defined as any particle consistent with Coal Ash.
. The method reporting level is 1 % and anything <1 % is considered a not -detected.
Quartz — Angular anisotropic particulate with low relief.
Feldspar — Angular to blocky anisotropic particulate, low to moderate relief, biaxial, can have polysynthetic twinning.
Clay — Sheet silicates with polycrystalline or display non -uniform extinction with low to moderate relief, and zero to low birefringence. Clay also refers to particles that are less than 2.0 microns.
Opaques — Opaque is a generic term for a particle that does not transmit light. Opaque minerals are distinguished from opaque bottom ash based on morphology of fracture.
Fly Ash — Isotropic to opaque spheres, agglomeration of spheres, and angular ash particles.
Organic Particulate — Pollen, plant and insect matter, and carbonaceous matter.
Carbonates — High birefringent, can be rhombohedral, with high relief.
Diatoms — Silica rich isotropic particles with various morphologies.
Mica — Sheet silicate with moderate to high relief and low birefringence, mono -crystalline, and normal extinction.
Miscellaneous Silicate — Isotropic and anisotropic silicates, with low to high relief, identification unsure and beyond the scope of the method to identify.
Amphibole — Elongated anisotropic particulate with moderate to high relief.
Coal — Irregular to angular particles with moderate opacity, edges and thin particles are reddish brown in color.
<1 % Fly Ash — Fly Ash observed, none counted.
ND — No Fly Ash detected.

• This report may not be used to claim product endorsement by NVLAP Lab Code 101208-0 or any agency of the U.S. Government.
• Sample(s) for this project were analyzed at our: Monroeville, PA (AIHA # 100364, NVLAP # 101208-0, NY ELAP # 10884) facility.
• If RJ Lee Group, Inc. did not collect the samples analyzed, the verifiability of the laboratory's results is limited to the reported values.
• For the purposes of this method, Fly Ash is defined as any particle consistent with Coal Ash.
. The method reporting level is 1 % and anything <1 % is considered a not -detected.
Quartz — Angular anisotropic particulate with low relief.
Feldspar — Angular to blocky anisotropic particulate, low to moderate relief, biaxial, can have polysynthetic twinning.
Clay — Sheet silicates with polycrystalline or display non -uniform extinction with low to moderate relief, and zero to low birefringence. Clay also refers to particles that are less than 2.0 microns.
Opaques — Opaque is a generic term for a particle that does not transmit light. Opaque minerals are distinguished from opaque bottom ash based on morphology of fracture.
Fly Ash — Isotropic to opaque spheres, agglomeration of spheres, and angular ash particles.
Organic Particulate — Pollen, plant and insect matter, and carbonaceous matter.
Carbonates — High birefringent, can be rhombohedral, with high relief.
Diatoms — Silica rich isotropic particles with various morphologies.
Mica — Sheet silicate with moderate to high relief and low birefringence, mono -crystalline, and normal extinction.
Miscellaneous Silicate — Isotropic and anisotropic silicates, with low to high relief, identification unsure and beyond the scope of the method to identify.
Amphibole — Elongated anisotropic particulate with moderate to high relief.
Coal — Irregular to angular particles with moderate opacity, edges and thin particles are reddish brown in color.
<1 % Fly Ash — Fly Ash observed, none counted.
ND — No Fly Ash detected.

. The method reporting level is 1 % and anything <1 % is considered a not -detected.
Quartz — Angular anisotropic particulate with low relief.
Feldspar — Angular to blocky anisotropic particulate, low to moderate relief, biaxial, can have polysynthetic twinning.
Clay — Sheet silicates with polycrystalline or display non -uniform extinction with low to moderate relief, and zero to low birefringence. Clay also refers to particles that are less than 2.0 microns.
Opaques — Opaque is a generic term for a particle that does not transmit light. Opaque minerals are distinguished from opaque bottom ash based on morphology of fracture.
Fly Ash — Isotropic to opaque spheres, agglomeration of spheres, and angular ash particles.
Organic Particulate — Pollen, plant and insect matter, and carbonaceous matter.
Carbonates — High birefringent, can be rhombohedral, with high relief.
Diatoms — Silica rich isotropic particles with various morphologies.
Mica — Sheet silicate with moderate to high relief and low birefringence, mono -crystalline, and normal extinction.
Miscellaneous Silicate — Isotropic and anisotropic silicates, with low to high relief, identification unsure and beyond the scope of the method to identify.
Amphibole — Elongated anisotropic particulate with moderate to high relief.
Coal — Irregular to angular particles with moderate opacity, edges and thin particles are reddish brown in color.
<1 % Fly Ash — Fly Ash observed, none counted.
ND — No Fly Ash detected.
