Rogers Energy Complex (Cliffside Steam Station)
Rutherford and Cleveland Counties
66 eligible households
Duke Energy has evaluated the feasibility and costs of providing a permanent replacement
water supply to eligible households, as required under G.S. 130A-309.21 1 (cl) of House Bill
630. Households were designated as "eligible" if any portion of a parcel of land crossed the
mile compliance buffer described in HB630 and if the household currently utilized well water as
the drinking water source. Although HB630 indicates that households are to be covered, Duke
Energy has included one (1) campground/travel trailer park within the eligible listing.
Undeveloped parcels were identified but were not considered "eligible" because wells are not
currently utilized as a drinking source.
Dewberry, a respected outside vendor, conducted the Potable Water Programmatic Evaluation
(attached); the evaluation consisted of a survey of eligible households and preliminary
engineering evaluation, cost estimate and schedule. Dewberry's report, for the most part,
assumes one metered connection per parcel; therefore, multiple homes may be serviced by one
connection. The total count in this proposed plan includes all final connections.
Based on the results of the Dewberry evaluation and the factors below, Duke Energy proposes
that 64 eligible well owners near Rogers Energy Complex (Cliffside) be offered the option of a
connection to a public water supply or the installation of a water treatment system, and two (2)
eligible households located on Dysart Road (identified as households 96 and 101 in the
Dewberry evaluation) be offered a water treatment system.
Grassy Pond Water Company (GPWC) has existing lines that serve the Rogers Energy
Complex, as well as customers west, south and east of the plant. To the west, lines run along
US-221 Alt and Old US-221A. Lines run along McCraw Road south and east of the plant.
Several of the eligible households can be served via existing lines that are on or across the road
from their properties. Where line extensions are required west of the plant, the closest
household is approximately 4,700 feet (0.89 miles) from the current line and the furthest
household is approximately 5,000 feet (0.95 miles). Where line extensions are required east of
the plant, the closest household is approximately 2,400 feet (0.45 miles) from the current line
and the furthest household is approximately 9,700 feet (1.84 miles).
A water treatment system is being recommended for the two households located to the west of
the plant along Dysart Road. While GPWC did not indicate any issues related to water quality
with running a municipal line to these two households, the cost to run the line just to these two
households is estimated at $487,000, or $243,500 each. The cost estimate indicates that
running the line to these two households is cost prohibitive. Total costs shown in the table
below exclude costs associated with running a public water supply line to the two households on
Dysart Road; therefore, the costs below are different than the costs included in Appendix D of
the Dewberry evaluation.

`C ENERGY,
Permanent Water Supply Proposal to DEQ - Rogers
Estimates prepared by Dewberry, in conjunction with design information provided by the local
water municipality, have revealed the cost to provide municipal water to the remaining 64
households is $2.5 million, or $39,000 for each household. While this cost estimate is greater
than the $35,000 for each household threshold agreed upon between Duke Energy and
NCDEQ, Duke is recommending offering public water to these households and, after well
owners have the opportunity to choose their preferred method of permanent water, re-evaluate
the overall cost and water quality of the system. If the number of households who choose
municipal water results in an overall cost that would be considered cost prohibitive or if
concerns arise from GPWC over water quality, Duke Energy will submit a revised plan to
NCDEQ and may recommend that all eligible household be offered installation and maintenance
of a water treatment system.
From initial discussions with GPWC and an evaluation of the system by Dewberry, additional
flushing of the line may be required to maintain water quality due to lower rural residential
demands and increased water travel time. The amount of flushing required, and whether water
quality would be maintained on a line with minimal connections, will continue to be evaluated
with GPWC as Duke Energy receives feedback from well owners on their preferred method of
permanent replacement water supply.
The performance standard for the public water system is the Federal MCLs. The performance
standard for the water treatment systems is also the Federal MCLs except for those constituents
identified in 2015 as having potential health concerns: arsenic, hexavalent chromium, cobalt,
iron, lead, manganese, sulfate and vanadium. For these constituents, the performance
standard will be either one-half of the MCL or the appropriate state standard, whichever is more
protective.
Duke Energy is currently evaluating an ion filtration treatment system; this system has been
successfully installed in other parts of the state, and initial results show it performs well in
reducing vanadium and hexavalent chromium, among other constituents. The costs shown
below are for a conceptual ion filtration treatment system. The final water treatment system will
be based upon the results of field studies.
Duke Energy has made efforts to identify all eligible households, but it is anticipated that a
nominal number of additional households will be identified during the initial outreach effort
conducted upon approved of this plan by NCDEQ. If the final number of households, or the final
number of households opting for municipal water supply, results in a conclusion different than
those stated in this preliminary plan, Duke Energy will revise the plan and submit the pertinent
information to NCDEQ for evaluation and approval. Also, the estimate assumes one public
water connection (i.e. meter box) per parcel; for parcels containing two households, the number
of connections will be determined based upon negotiations between the well owner(s) and the
municipality. Well owners will be responsible for making the decision for their parcels. Only
households within the'/2 mile boundary and served by well water at the time of the submittal of
this plan will be eligible for a permanent water supply as part of HB630.

`C ENERGY,
Permanent Water Supply Proposal to DEQ - Rogers
The Dewberry evaluation includes a project schedule based on Dewberry's past experience
installing public water systems. This preliminary schedule indicates that a permanent water
supply will be available in August 2018, which meets the October 15, 2018 deadline in HB630.
Upon submittal of this plan to NCDEQ, Duke Energy will begin negotiations with the local
municipality and a more detailed schedule will be developed. If the municipality's schedule
results in an implementation date extending beyond October 15, 2018, Duke Energy will request
an extension and look at whether other contingency measures need to be implemented.

Executive Summary
This Phase II evaluation is structured to comply with the requirements of North Carolina House Bill 630:
Section 13oA-309.211.(ci) of House Bill 63o requires provision of permanent water supply for each household that has a
drinking water supply well located within a 1/2 mile radius from the established compliance boundary of a coal combustion
residuals impoundment, and is not separated from the impoundment by the mainstem of a river, or other body of water that
would prevent the migration of contaminants through groundwater from the impoundment to a well.
To address the provisions of House Bill 63o, Dewberry performed this Phase II preliminary engineering evaluation to supply
potable water to residents within a 1/2 mile of the compliance boundary. Preparation of this report is intended to comply with
the House Bill 63o requirement to make a report submittal to the North Carolina Department of Environmental Quality (DEQ)
by December 15, 2o16.
On July 27, 2016 a project review meeting was held at the Cliffside Steam Station. Representatives from Duke Energy,
Dewberry, and Grassy Pond Water Company (GPWC) attended the meeting.
Detailed Phase II mapping was developed using Cleveland and Rutherford County property maps that show each household in
the 1/2 mile compliance buffer. Dewberry visually observed the households shown on the Phase II mapping on July 27, 2016.
A household database was developed using Cleveland and Rutherford County tax records tied to the GIS shape file which
identifies the property owner and the address for each household within the 1/2 mile compliance buffer.
Based on our site observations and the Phase II mapping, it appears to be technically feasible to install the potable water main
in the public road right of way or along private roads using conventional construction methods. Easements appear to be
required along approximately 30% of the water line extensions and numerous service line extensions.
A schedule was prepared in part to show milestone dates needed to comply with House Bill 630 which states the following:
• Report submittal to the North Carolina DEQ no later than December 15, 2016.
• DEQ renders a final decision to approve or disapprove the report no later than January 15, 2017.
• Permanent replacement water supplies are provided no later than October 15, 2o18.
If each of the milestone dates are met, the schedule indicates that project completion can occur in August of 2o18 which meets
the House Bill 630 schedule requirement for permanent replacement water supplies.
An opinion of probable cost was developed to provide potable water service to 66 households within the 1/2 mile compliance
buffer. The 66 households are served from 57 water line connections as multiple parcels have more than one household per
connection. The estimated costs are summarized below:
0 Dewberry Duke Energy Cliffside Steam Station Phase 11 Potable Water Programmatic Evaluation 2
The potable water connection cost estimate includes a 25% contingency which is deemed consistent with a project at the
preliminary engineering level of detail. To be conservative the cost estimate assumes that all 66 households will receive potable
water service.
This report provides additional detail on the Project Approach, Basis of Design, and Site Analysis. Cliffside Steam Station
mapping is provided in Appendix A. The household database is provided in Appendix B. The Cliffside Steam Station Potable

1. Introduction and Project Approach
PROJECT INTRODUCTION
During the Phase I programmatic potable water evaluation desktop study, concept level mapping was developed showing the
Cliffside Steam Station location, the potential potable water tie-in location, and potential pipe routing to residents within a 1/2
mile of the compliance boundary. We used the Phase I mapping to develop a concept level cost estimate with a 40
contingency. During this Phase II evaluation sufficient preliminary design work has been performed to prepare a cost estimate
with a 25% contingency.
This Phase II evaluation is structured to comply with the requirements of North Carolina House Bill 630: Section 13oA-
309.211.(cl), which requires provision of permanent water supply for each household that has a drinking water supply well
located within a 1/2 mile radius from the established compliance boundary of a coal combustion residuals impoundment, and is
not separated from the impoundment by the mainstem of a river, or other body of water that would prevent the migration of
contaminants through groundwater from the impoundment to a well.
To address the provisions of House Bill 63o referenced above Dewberry has performed a Phase I screening level evaluation and
this Phase II preliminary engineering evaluation of the technical and economic feasibility to supply municipal potable water to
residents within a 1/2 mile of the compliance boundary. The Phase II evaluation results will be used to prepare this report for
submittal to the North Carolina Department of Environmental Quality (DEQ) by December 15, 2o16 as required by House Bill
630.
Using publicly available information Dewberry evaluated the following criteria to perform the Phase II Cliffside Steam Station
preliminary engineering study:
• Identified public road right-of-way widths and ownership along the pipe route
• Evaluated feasibility to install the proposed water main within the unpaved shoulder of an NC DOT roadway
• Documented approximate location of U.S. waters, including possible wetlands shown in the U.S. Fish & Wildlife Service
National Wetlands Inventory (as applicable)
• Identified potential jurisdictional and permitting authorities to establish permitting needs
• Estimated potential easement acquisition areas (estimated square footage and number of parcels affected)
• Evaluated potential conflicts with known existing utilities
• Estimated the pipeline length and pipe diameter(s) for the water main and the individual service lines
• Evaluated the potential need for a water booster pump station or elevated tank to sustain adequate water pressure
• Evaluated the water age and potential need for supplemental disinfection
• Evaluated the potential need/requirement for fire hydrants and hydrant quantity
• Evaluated potential construction methods and challenges
• Evaluated potential municipal water system future improvements based on published Capital Improvement Plan (CIP) or
published Master Plan

PROJECT APPROACH
Dewberry contacted the Duke Energy Community Relations District Manager to discuss the information needed to execute the
Phase II evaluations, and to arrange for a subsequent meeting with GPWC.
On July 27, 2o16 a project review meeting was held at the Cliffside Steam Station to discuss execution of this Phase II
preliminary evaluation and subsequent project execution. Representatives from Duke Energy, Dewberry, and GPWC attended
the meeting. The primary purpose of the meeting was to confirm the water distribution system tie-in location, system pressure,
pipe size, and water quality at the tie -location, capacity limitations, and whether there are future planned water system
projects that could impact the Phase II evaluation. Dewberry also inquired as to whether any households within a 1/2 mile of
the compliance boundary were presently being served by municipal potable water. Following the meeting, Duke Energy,
GPWC, and Dewberry performed an initial drive -by observation of the potable water pipe route.
During Phase I Dewberry obtained municipality mapping of the potable water distribution system and then developed draft
maps showing the Cliffside Steam Station, the respective potable water distribution system tie-in location, and the water main
pipe routing. We used the Duke Energy Drinking Water Receptor Surveys for Coal-fired Power Stations developed in 2014 to
show compliance boundaries and the water supply wells within a 1/2 mile of the compliance boundary. The maps were
prepared using GIS as the native software.
During Phase II we developed more detailed mapping based on Cleveland and Rutherford County property maps to identify
property owners and household addresses within the 1/2 mile compliance buffer. For the Phase II analysis property parcels
that were wholly or partly within the compliance buffer were included in the evaluation.
Using the Phase II mapping a database of property owners and household locations was developed. Dewberry also contacted
GPWC to confirm residents along the existing water mains within the compliance buffer who are currently connected to the
system. This information allowed for identification of residents who were located along the existing water line but not
connected to the water system. We also prepared a project schedule.
Dewberry then developed an opinion of probable cost for the installation of piping infrastructure to the potable water tie-in
location. We used vendor budgetary costs for the primary capital equipment and used cost factors to estimate the installation
costs. We did not obtain contractor installation cost estimates for this evaluation. Dewberry reviewed the cost data with Duke
Energy to obtain concurrence on the methodology and the allowances applied.

2. Phase II Basis of Design
The purpose of this section is to document basis of design assumptions that were used to prepare the Cliffside Steam Station
mapping, opinion of cost, and schedule.
2.1 POTABLE WATER CONNECTION MAPPING
Key assumptions for the potable water connection mapping are as follows:
Potable water piping is routed along state roads and will use municipality/county existing easements, where possible.
Approximately 30% of the proposed water main is located on private roads, which will require private easements.
Power transmission line easements will not be used for installation of the potable water piping.
2.2 MUNICIPAL POTABLE WATER CONNECTION OPINION OF
PROBABLE COST
Key assumptions for the potable water connection cost estimates are as follows:
Item 1 and Item 4 on the cost estimate shows 6" and 4" ductile iron, respectively, for the potable water main pipe. The 4"
and 6" diameters are considered conservative pipe sizes to meet the water demand of the households within the
compliance buffer and complies with the GPWC conceptual design plans. The conceptual design also requires use of
ductile iron material for construction, per GPWC standards.
The 4" and 6" water main pipes are not sized to meet fire flow as that is not required for potable service by GPWC.
Items 1 through io on the cost estimate show material cost for the piping, valves, and associated fittings. The sum of Items
1 through io is shown as a separate line item. A 30% cost factor is then applied to the summed value to estimate the cost to
install the pipe, valves, and fittings. The cost estimate quantities are based on the Cliffside Steam Station mapping and
assumptions stated on the cost estimate. The unit costs are based upon vendor budgetary costs and cost data we have from
recent similar projects.
The sum of quantities for items 24-25 on the cost estimate indicates there are 57 potable water line connections. The 16 2"
service taps are for service connections exceeding 1,000 feet or parcels with multiple connections. The 413/4" service taps
are for individual household connections relatively close to the proposed main and meter box connection.
The number of connections shown in the cost estimate is based upon the Cleveland and Rutherford County property maps
and drive -by observations.
No commercial/industrial facilities were identified within the 1/2 mile buffer so there is no allowance to provide potable
water to such facilities.
Items ii through 19 and items 24 through 28 are installed cost, so a 30% installation cost factor was not applied.
Items 20 through 23 are material cost, so a 30% installation cost factor was applied.
Items 1 through 28 are summed and shown as a SUBTOTAL. Cost factors are then applied to the SUBTOTAL to estimate
the balance of the project costs. We have applied a 25% contingency which is deemed consistent with a preliminary
engineering evaluation.
Additional assumptions that Dewberry used to prepare the opinion of probable cost are provided as foot notes in
Appendix D.
Contractor General Conditions are included for the duration of on -site construction phase activities.
Easement acquisition includes the cost to compensate land owners for water lines extended down private roads and/or
across private property.

3. Site Analysis
3.1 STATION MAPPING AND HOUSEHOLD DATA
The Phase II overall map in Appendix A shows the proposed tie-in location to the existing GPWC potable water supply system,
indicating that over 3 miles (~18,000 LF) of new potable water piping is required to serve households within the 1/2 mile
compliance buffer.
GPWC has verbally agreed to own and operate the expanded potable water system.
The Phase II Site map and sheets in Appendix A were prepared by overlaying Cleveland and Rutherford County property maps
onto the compliance boundaries detailed in the Duke Energy Drinking Water Receptor Surveys for Coal-fired Power Stations
developed in 2014. The Appendix A Site map shows the 1/2 mile compliance buffer and 11 rectangular property map sections. 11
sheets were then prepared that show the water main route, individual households, and household service line connections
within the 1/2 mile compliance buffer. During the July 27, 2016 drive -by, Dewberry visually observed households shown in the
Appendix A sheet mapping.
The household database in Appendix B was created from the Cleveland and Rutherford County tax records tied to the GIS
shape file which identifies the property owner and the address for each household within the 1/2 mile compliance buffer,
including parcels of land with no residents (empty lot). The parcel data listed on the spreadsheets also includes Parcel ID, Land
Use, Easement Requirement, and anticipated Water Demand for each property. It should be noted that a number of parcels
had more than one home located on the property; in this case one meter was assumed with length of service line assumed to
extend to each home from a single meter. Engineering judgment was utilized in cases where homes were located out of sight
from the road and multiple structures could be seen during an aerial review. It should also be noted that one empty parcel of
land formerly served as a RV campground. To be conservative, one water service line was extended to the RV parking area.
Review of the mapping from Appendix A allowed for estimates of the required private easement areas around the Steam
Station. The potable water main proposed to serve residents around the Cliffside Steam Station will require private easement
acquisition along two private roads; Riverfront Drive and Downriver Drive. Numerous service line easements will be required
as well. Typical municipal easement standards were followed around the Cliffside Steam Station, since GPWC does not have
published easement acquisition standards. The easement area was calculated by multiplying the length of the water main on
private property by 30 feet. The area was then multiplied by 50% of the average land value (per acre) as indicated by public tax
assessment for properties around the Cliffside Steam Station, providing an estimate of the easement cost. Temporary
easements were not included in the calculation.
3.2 FIELD OBSERVATIONS
As shown in Appendix A, the water main piping will be installed along state roads, where possible. During the July 27, 2016
drive -by Dewberry did not observe rail road crossings or other above grade conflicting physical features that are anticipated to
have a significant impact on the construction cost or schedule.
Based on our observations and the Phase II mapping, it appears to be technically feasible to install the potable water main in
the public road right of way or along the side of the private roads using conventional construction methods, such as an open
trench with pipe bedding material. A few boulders were observed but appeared minimal and would allow water main
installation without blasting. Approximately two water main road crossings and 16 service line road crossings will be required.
0 Dewberry Duke Energy Cliffside Steam Station Phase 11 Potable Water Programmatic Evaluation 7
Road crossings are planned to be subsurface boring to avoid open road cuts, and traffic impacts. It should be noted that the
crossing count could be modified based upon final design and which side of the road the water main will be installed.
Dewberry did not observe surface water or apparent wetland infrastructure conflicts. This is consistent with USGS mapping
and the U.S. Fish & Wildlife Service National Wetlands Inventory.
During the drive -by Dewberry did not observe potential conflicts with known existing utilities. At present the 66 households
within the 1/2 mile compliance buffer do not have public water or sewer. Natural gas main markers were not observed during
the drive -by, but are typically located within the state road right of way and are smaller in diameter than water piping,
therefore they would not cause a significant conflict. Aboveground electric was observed and therefore not considered an
impediment to water main installation.
Dewberry observed the public road right-of-way and private road widths and evaluated the feasibility to install the proposed
water main within the unpaved shoulder of NC DOT roadway or within the private road shoulder. We noted a few locations
where the right of way limitations may make water main installation challenging but not overly complicated. In some areas it
may be necessary to conduct subsurface utility evaluation and route the water main accordingly. In areas that we could not
determine right of way status (public or not) or areas where private property may have been constructed onto right of way, we
either provided an allowance for water main easement, or the construction impact is accounted for in the cost estimate as a
renovation allowance.
3.3 OTHER CONSIDERATIONS
The GPWC is a relatively small water system who owns the infrastructure, manages the water supply, and meters and bills for
water use. Moreover, GPWC sources their potable water from the Broad River Water Authority (a NC system) and the Gaffney
Water Plant (a SC system). GPWC consults with Summit Engineering Group for guidance on standards, water line extensions,
and management of state and local water guidelines.
Summit Engineers estimates the pressure in the system at the Broad River connection to be approximately 100-135 psi. This
pressure is more than adequate for rural residential domestic service and in some cases will be excessive. GPWC confirmed
that their existing customers in areas of higher pressures may use pressure reducing valves (PRVs), therefore, Dewberry
included PRVs for each of the 66 households to be served around the Cliffside Steam Station. The Broad River Water Authority
has confirmed their capacity to serve the residents around Cliffside through the interconnection with GPWC. Therefore based
on this preliminary information, the flow capacity and pressure is deemed adequate to serve the 66 households in the 1/2 mile
compliance buffer.
Based on information from the Broad River Water Authority, the approximate chlorine residual at the pump station serving
the Cliffside area is approximately 1.4 mg/L. However, water system disinfection residual tends to breakdown as water age
increases and this can be caused by lower rural residential demands and increased travel time. Two common ways to prevent
loss of disinfection residual are 1.) disinfection boosting, and 2.) systematic flushing to maintain flow and minimize water age.
The water system extensions, as planned by Dewberry, utilize the minimal diameter pipe for service and considers system
flushing to be required in this area. The proposed water system extension for 66 households at approximately 48o gpd will
increase the water age. GPWC and their engineers have considered the increase in water age and they think the water quality
will be maintained and are not concerned.

4. Regulatory Permitting
The water main design will be required to adhere to requirements of the following agencies and permitting authorities. Each
permit will require a separate set of documentation and will be submitted individually to the respective permitting agency. The
timeline for submittal and approval is presented in the Cliffside Steam Station Potable Water Schedule detailed in Appendix C.
• NCDOT Right-of-way Encroachment Agreement, Primary and Secondary Roads
• NCDEQ, Division of Land Quality, Erosion and Sedimentation Control Permit
• NCDEQ, Division of Water Resource, Public Water Supply Permit
0 Dewberry Duke Energy Cliffside Steam Station Phase 11 Potable Water Programmatic Evaluation 9
5. Schedule
The Phase II project schedule is provided in Appendix C.
The schedule was prepared to illustrate milestone dates needed to comply with House Bill 630 which states the following:
• "No later than December 15, 2016 an impoundment owner shall submit information on permanent replacement water
supplies proposed to be provided to each household"
• "The Department shall evaluate information submitted by the impoundment owner and render a final decision to approve
or disapprove the plan, including written findings of fact no later than January 15, 2017"
• "As soon as practical, but no later than October 15, 2018 the owner of a coal combustion residual surface impoundment
shall establish permanent replacement water supplies"
The schedule indicates DEQ report submittal on December 15, 2016 and DEQ approval by January 15, 2017. The schedule
includes an initial go day negotiation period for development and execution of a Water Authority/Duke memorandum of
understanding (MOU). The schedule is subject to change dependent upon the milestone dates for the MOU, the
approval/comments from DEQ, and the resident input regarding permanent water supply choice.
The balance of the schedule is deemed typical for a municipal design -bid -build water line improvement project and plans for
all households to connect to public potable water. The schedule indicates an end date of August 2018 which meets the October
15, 2018 deadline.

6. Opinion of Probable Cost
The Phase II opinion of probable cost is provided in Appendix D. The opinion of probable cost was prepared in accordance
with the basis of design criteria in Section 2.2 of this report.
The opinion of probable cost indicates that the total estimated construction cost is approximately $2,997,000, which equates
to approximately $45,000 per household. A 25% contingency is included.
The Phase II opinion of probable cost includes individual allocations for the service connection lines and meters (items 20
through 28) that equates to approximately $1o,000 per new connection. We arrived at that allocation as follows:
For items 20 through 23 the service line lengths were measured for each household using the Phase II sheet mapping.
Items 22 and 23 are for miscellaneous fittings associated with the service line connections, including pressure reducing
valves.
For items 24 and 25 the meter/meter box allowance was developed from vendor quotations and from recent bid tabs we
have for similar projects.
Item 26 is for road crossings where the connection to be served is on the opposite side of the road from the water main.
Items 27 and 28 represent site costs associated with approximately 16,000 feet of new service line piping.
