David,
Thanks for the call and asking. I received this on Decemb27, 2018 and was supposed to send in to you after I retuned
form the holidays. Sorry this has slipped through the cracks. Please do not hesitate to contact me if you have any
questions. I believe you and Randy Martin/Headwaters discussed the parameters for this sampling in November 2018
prior to the work being completed.

Reference: Cashiers Lake Dredge Plan — Pre -Dredge Environmental Review
Cashiers Canoe Club Development, LLC
Cashiers Lake, Cashiers, Jackson County, North Carolina
Headwater Proposal #118-65A
Dear Mr. Martin:
Headwater Environmental, Inc. (Headwater) is pleased to submit this letter report summarizing
sediment sampling activities at the Cashiers Lake Dredging Project, located in Cashiers, Jackson
County, North Carolina (the "site"). This report contains site background, a description of site
activities, results, and conclusions.
BACKGROUND AND PURPOSE
According to plans provided to Headwater by the Client (RKM Resources, PLLC), the site is an
approximate 24 -acre lake, of which +/- 5 -acres of wetlands will be impacted during proposed
dredging activities. Dredging is expected to be to a depth of four feet below grade surface (ft-bgs)
or less.
On April 24, 2018 ClearWater Environmental Consultants, Inc. submitted a permit application on
behalf of Cashiers Canoe Club Development, LLC for the Cashiers Lake Dredge and Development
Project. On June 28, 2018 the Department of the Army (DA) responded with a Corps Comment
and Request for Additional Information notice.
The purpose of this assessment, detailed herein, is to address Item 12 within the DA response.
Item 12 is detailed as follows: "Provide details of the characteristics and composition of the
materials to be dredged, including sampling data to determine the potential presence of regulated
pollutants/contaminants."
To clarify this request Headwater spoke with Mr. David Brown with the Army Corps of
Engineers, on November 16, 2018. Mr. Brown requested to defer the inquiry to the North
Carolina Department of Environmental Quality (DEQ), Division of Water Resources. Headwater
spoke with Mr. Kevin Mitchell at the DEQ, within the Asheville Regional office. Mr. Mitchell
referred Headwater to Mr. Ervin Lane with the Division of Waste Management (DWM) in
Raleigh. Mr. Lane indicated the assessment must be inclusive of volatile organic compounds
(VOCs), semi -volatile organic compounds (SVOCs), and Resource Conservation and Recovery
Act (RCRA) metals and be considered representative of the proposed dredging material.
Additionally, Mr. Lane indicated a "background" sample should be collected for RCRA metals to
allow for comparison to samples acquired from the proposed dredge area.

Cashiers Lake — Pre -Dredge Environmental Review
Cashiers, Jackson County, North Carolina
Headwater Project #2018-110A
On November 20, 2018 Headwater provided Mr. Brown with a summary of the proposed sampling
scope, and requested Mr. Brown provide comment if the proposed scope would not address the
DA's Request for Additional Information notice. No response was received from Mr. Brown.
The following sections provide detail of the completed scope of service and the associated
results.
SITE ACTIVITIES
SAMPLE COLLECTION
On November 28, 2018, six sediment samples were collected from within the proposed
dredging area of Cashiers Lake and from two "background" locations (totaling four samples).
Each sample was collected at an area considered to be representative of site conditions at that
location.
Sampling locations are depicted on the attached figure. At each location, soil samples were
collected from a 0 -to -2 ft-bgs and a 2 -to -4 ft-bgs depth interval. Additionally, two background
samples (BG -1 and BG -2) were collected for analysis of RCRA metals from outside the
dredging footprint at the same depths as the lake dredge samples (SB -1 through SB -3).
Samples were collected utilizing a stainless-steel hand auger. The hand auger was cleaned with
an Alconox solution and rinsed with de -ionized water before and between advancement at each
sampling point.
SAMPLE ANALYSIS
Based on direction provided by Mr. Lane of the DEQ-DWM, sediment samples (SB -1 through
SB -3) were analyzed for:
• Volatile Organic Compounds (VOCs)
• Semi -Volatile Organic Compounds (SVOCs) and
• RCRA metals
Sediment samples collected from the background locations (BG -1 and BG -2) were analyzed for
RCRA metals only.
Collected sediment samples were placed in laboratory -supplied containers. The containers were
labeled and placed in a cooler on ice. The cooler was then transported under chain -of -custody
protocol to Pace Analytical Services, Inc. (Pace) of Asheville, North Carolina for laboratory
analysis.
SEDIMENT ASSESSMENT RESULTS
No constituents of concern were identified above the applicable regulatory limits with the
exception of total Chromium in all 10 samples (including background samples). Headwater
requested the laboratory speciate total Chromium to allow for a more thorough comparison to
regulatory standards. Once speciated (trivalent and hexavalent), Chromium concentrations were
below applicable regulatory standards.
Sediment sample results are summarized in Table 1. The laboratory analytical report is included
as Appendix A.

CONCLUSION
Based on the analytical results of the sediment samples collected from Cashiers Lake,
regulatory limits were not exceeded. In addition, background samples expressed results similar
to those collected from the proposed dredging area.
Thank you for the opportunity to provide environmental services. If you have questions, or if we
can be of additional service, please contact us.

QUALIFIERS
Project: 2018-110A
Pace Project No.: 92408877
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI -The NELAC Institute.
LABORATORIES
PASI-A Pace Analytical Services - Asheville
PASI-C Pace Analytical Services - Charlotte
ANALYTE QUALIFIERS
1g The internal standard response is below criteria. No hits associated with this internal standard. Results unaffected by
high bias.
H1 Analysis conducted outside the EPA method holding time.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
N2 The lab does not hold NELAC/TNI accreditation for this parameter.
R1 RPD value was outside control limits.
