Subject: Interim Project Status Update - Asheville Steam Electric Plant
Comprehensive Site Assessment (CSA) activities pertaining to the Asheville Steam Electric
Plant continue. The CSA document, when completed, will be used to produce a Corrective
Action Plan (CAP). The information included in this technical memorandum facilitates further
discussion and planning of the CSA. Topics include:
• Low -yield well sampling results
• Open -borehole well status and recommendations
• Flow transect and cross-section recommendations
LOW -YIELD WELL SAMPLING
In an email dated April 11, 2018, the North Carolina Department of Environmental Quality
(DEQ) requested that all wells and piezometers that are not completely dry be purged and
sampled for boron and field parameters at least once. The request for such sampling included
these wells:
AMW-2BRL CB-1BR CB-1BRL MW-3BR
MW-7BR MW-8BR MW-SBRL MW-15BR
MW-19BR MW-19BRL MW-24BR MW-27BRL
MW-28BRL GW-5 P-102 PZ-16
Significant observations from this sampling event include:
• Eight (8) of the 16 locations were suitable for sampling.
None of the samples indicated boron concentrations in groundwater greater than the 2L
Standard (700 µg/L).
Boron concentrations in samples from two locations, MW-3BR and PZ-16, were
significantly greater than the detection limit (50µg/L) but similar to concentrations in
samples taken from adjacent or nearby bedrock monitoring wells.

Interim Project Status Update — Asheville Steam Electric Plant June 25, 2018
Asheville Steam Electric Plant Page 2 of 4
High pH and turbidity, common in these low -yield bedrock wells, is presumably
influenced by drilling, well installation, and technical difficulty developing low -yield
wells.
SynTerra does not recommend additional sampling of these wells. SynTerra
recommends abandonment or installation of screened wells at open -borehole locations.
Of the 16 wells listed above, CB-1BR, MW-3BR, MW-7BR, MW-8BR, MW-15BR, MW-19BR,
MW-24BR, and PZ-16 were purged dry using a submersible pump on April 25, 2018. Those
wells were sampled for boron and field parameters on April 26, 2018, using a bailer. Requested
sample locations and locations that could be sampled are highlighted on Figure 1. Copies of the
low -yield sampling logs are included as Attachment 1, and analytical data reports are included
as Attachment 2. Boron analysis and field indicator parameters are summarized in the attached
Table 1.
P-102 was observed as completely dry, and the recharge rate at GW-5 was too low to allow
sampling. The remaining wells — AMW-2BRL, CB-1BRL, MW-8BRL, MW-19BRL, MW-27BRL,
and MW-28BRL — are all deep bedrock open -borehole wells that contain large volumes of
water. Purging and sampling the remaining open -borehole wells will require substantial time
and a larger pump that enables effective dewatering. Another possibility is the use of passive
diffusion bag samplers (PDB) at these locations. However, because of the low recharge rates in
these wells, development of the boreholes was not completed. Results from the PDBs would be
considered approximate or unusable because water in the borehole likely remains from the
drilling process and would not be representative of the formation.
OPEN -BOREHOLE WELL STATUS
Open -borehole bedrock wells are present at the Asheville Steam Electric Plant. The original plan
was for screened bedrock wells; however, a viable water -producing fracture zone was not
encountered at these locations. These wells have been gauged to measure head potential of
groundwater within the primary porosity of the bedrock matrix. Recently, select open -borehole
and low -yield wells were sampled for boron as described above.
Open -borehole wells that are considered viable monitoring locations include:
• EXT-A
• EXT-1
• EXT-2
• MW-16BRL
• MW-20BR
• MW-26BRL
Open -borehole wells that are not considered viable monitoring locations include:
• APZ-30
• AMW-2B
• AMW-2BRL

• CB-1BRL
• CB-8BRL
• CCR-102BR
• MW-8BRL (EXT-B)
• MW-19BRL
• MW-27BRL
• MW-28BRL
Since these boreholes do not intersect water bearing fracture sets, the risk of cross -
communication through the borehole is mimimized; however, it is prudent to abandon these
wells as soon as they are determined to be of limited use for monitoring future site conditions.
Considering recharge rates, recent analytical results, and the expansive groundwater
monitoring network, SynTerra recommends the following actions for existing open -borehole
locations:
• Abandonment: APZ-30, AMW-213, AMW-2BRL, CB-1BRL, CB-8BRL, CCR-102BR, EXT-
•, EXT-D, MW-3BRL, MW-8BRL(EXT-B), MW-19BRL, MW-27BRL, and MW-28BRL
• Completion of nested wells (after pumping tests): MW-16BRL and MW-26BRL
• Completion of a single -screened well: EXT-A, EXT-2, and MW-20BR
• EXT-1, currently an extraction well, should be completed as a monitoring well or
abandoned once groundwater extraction stops
Table 2 presents bedrock well detail information and justification of recommendations. Figure 2
shows locations of recommended well abandonments.
Screened wells determined to be of limited use to monitoring future conditions recommended
for abandonment include PZ-16 (persistant elevated turbdity) and GW-5 (dry well adjacent to
MW-3 and CB-3 clusters).
FLOW TRANSECT AND CROSS-SECTION RECOMMENDATIONS
Four flow transects have been identified to evaluate groundwater characteristics over an area
from the source areas (1964 ash basin and former 1982 ash basin) to potential groundwater
receptors such as the wetlands complex and French Broad River. The four transects proposed
for evaluation are presented as A -A', B-B', C-C', and D-D' on Figure 3. Those transects will be
incorporated into the geochemical model and further evaluated within the CSA.
Cross -sections that will allow three-dimensional visualization and understanding of
groundwater flow and constituent occurrence across the investigation area are recommended
along lines B-B', D-D' and E-E'.

been qualified by Duke Energy to perform these analyses except where noted.
Data Package:
This data package includes analytical results that are applicable only to the samples described in this narrative. An estimation of
the uncertainty of measurement for the results in the report is available upon request. This report shall not be reproduced, except
in full, without the written consent of the Analytical Laboratory. Please contact the Analytical laboratory with any questions. The
order of individual sections within this report is as follows:
Job Summary Report, Sample Identification, Technical Validation of Data Package, Analytical Laboratory Certificate of Analysis,
Analytical Laboratory QC Reports, Sub -contracted Laboratory Results, Customer Specific Data Sheets, Reports &
Documentation, Customer Database Entries, Test Case Narratives, Chain of Custody (COC)
Certification:
The Analytical Laboratory holds the following State Certifications : North Carolina (DENR) Certificate #248, South Carolina
(DHEC) Laboratory ID # 99005. Contact the Analytical Laboratory for definitive information about the certification status of
specific methods.
