Cape Fear Proposed Permanent Water Solution_20161202

Permanent Water Supply Proposal to DEQ — Cape Fear
Cape Fear Steam Station
Chatham County
4 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 or
bottled water (under Duke Energy's bottled water program) as the drinking water source.
Undeveloped parcels were identified but were not considered "eligible" because groundwater
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 a 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 the four (4) eligible households near Cape Fear be offered the option of a connection to a
public water supply or the installation of a water treatment system.
Chatham County already has a municipal line located along Corinth Road; therefore the
households would require only service lines, ranging from approximately 140 feet to 800 feet.
Since only service lines are required, no minimum number is needed for the installations to
remain cost-effective.
From initial discussions with Chatham County and evaluation of the system by Dewberry, the
current system has adequate water capacity and the water quality could be maintained with the
addition of the eligible households.
The performance standard for the public water system is the Federal MCLs. The performance
standard for the water treatment system 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 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
DUKE
�, ENERGY:

Permanent Water Supply Proposal to DEQ — Cape Fear
conducted upon approval of this plan by NCDEQ. If the final number of households, or the final
number of households opting for public water supply, results in a conclusion different than those
stated in this preliminary plan, Duke Energy will revise and submit the new plan 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.
The Dewberry evaluation includes a project schedule based on their past experience installing
public water systems. The preliminary project schedule indicates that a permanent water supply
will be available by May 2017. Upon submittal of this plan to NCDEQ, Duke Energy will begin
negotiations with the local municipality and a more detailed schedule will be developed. The
schedule will also depend on the time required to educate the eligible households on their
choices. If the installation schedule shows 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 August 19, 2016 a project review meeting was held at the Chatham County Administration Building in Pittsboro, NC.
Representatives from Duke Energy, Dewberry, and Chatham County attended the meeting.
Detailed Phase II mapping was developed using Chatham 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.
A household database was developed using Chatham 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.
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 May of 2017 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 four households within the 1/2 mile compliance
buffer. The four households are proposed to be served from four water line service connections from an existing waterline. The
estimated costs are summarized below:
The potable water connection cost estimate includes a io% contingency which is deemed appropriate for a water service line
project that does not require a new waterline extension. To be conservative the cost estimate assumes that all four households
will receive potable water service.

1. Introduction and Project Approach
PROJECT INTRODUCTION
During the Phase I programmatic potable water evaluation desktop study, concept level mapping was developed showing the
Cape Fear 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 lo% contingency.
This Phase II evaluation is structured to comply with the requirements of North Carolina House Bill 630: Section 13oA-
309.211. (CI), 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 the submittal to
the North Carolina Department of Environmental Quality (DEQ) by December 15, 2016 as required by House Bill 630.
Using publicly available information Dewberry evaluated the following criteria to perform the Phase II Cape Fear Steam Station
preliminary engineering study:
• 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)
• Estimated the pipeline length and pipe diameter(s) for individual service lines
• Evaluated the potential need for a water booster pump station or elevated tank to sustain adequate water pressure
• Evaluated the potential need for supplemental disinfection
• Evaluated the potential need/requirement for fire hydrants and hydrant quantity
• Evaluated potential construction methods and challenges

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 Chatham County.
On August 19, 2016 a project review meeting was held at the Chatham County Administration Building in Pittsboro, NC to
discuss execution of this Phase II preliminary evaluation and subsequent project execution. Representatives from Duke
Energy, Dewberry, and Chatham County 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.
During Phase I Dewberry obtained municipality mapping of the potable water distribution system and then developed draft
maps showing the Cape Fear Steam Station, the respective potable water distribution system tie-in location, and the water line
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 Chatham 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
Chatham County to confirm residents along the existing water lines 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 new service line piping and related infrastructure.
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 Cape Fear 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:
The area around the station does not require installation of new waterline piping as all four households can be served from
an existing waterline.
Private easements will be required in one area.
2.2 MUNICIPAL POTABLE WATER CONNECTION OPINION OF
PROBABLE COST
Key assumptions for the potable water connection cost estimates are as follows:
• The sum of quantities for items 21-22 on the cost estimate indicates there are four potable water line connections. The
four 3/4 inch service taps are for individual household connections close to the proposed main and meter box connection.
• The number of connections shown in the cost estimate is based upon the Chatham County property maps and drive -by
observations.
Items 21 through 25 are installed cost, so a 30% installation cost factor was not applied.
Items 18 through 20 are material cost, so a 30% installation cost factor was applied.
• Items 1 through 25 are summed and shown as a SUBTOTAL. We have applied a io% contingency which is deemed
consistent with a water service line connection project.
• Additional assumptions that Dewberry used to prepare the opinion of probable cost are provided as foot notes in
Appendix D.
• Contractor General Conditions are deemed unnecessary for this station as the installation will not require a trailer or other
on -site infrastructure to support the project.
• Easement acquisition includes the cost to compensate land owners for service lines extended across private property.

3. Site Analysis
3.1 STATION MAPPING AND HOUSEHOLD DATA
The Phase II overall map in Appendix A shows the existing Chatham County potable water supply system, indicating that a
new potable waterline extension is not required to serve households within the 1/2 mile compliance buffer. Four service lines
will be installed from an existing waterline to serve households not currently connected to Chatham County water.
Chatham County will continue to own and operate the potable water system proposed to serve the four additional households.
The Phase II Site map and sheets in Appendix A were prepared by overlaying Chatham 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 two rectangular property map sections. The two
sheets were prepared to show the existing water line route, individual households, and new service line connections within the
1/2 mile compliance buffer. Dewberry visually observed households shown in the Appendix A sheet mapping.
The household database in Appendix B was created from the Chatham 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. 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.
Review of the mapping from Appendix A allowed for estimates of the required private easement areas around the Steam
Station. The potable water service lines proposed to serve residents around the Cape Fear Steam Station will require private
easement acquisition in one area. Typical municipal easement standards were followed around the Cape Fear Steam Station.
The easement area was calculated by multiplying the length of the water line on private property by 30 feet. The area was then
multiplied by go% of the average land value (per acre) as indicated by public tax assessment for properties around the Cape
Fear 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, installation of new waterline piping is not required for this project. Therefore there are no road
crossings, railroad crossings, or other conflicting physical features associated with extension of a new waterline.
Based on our observations and the Phase II mapping, it appears that four service line road crossings will be required.
Dewberry did not observe surface water or apparent wetland infrastructure conflicts associated with the service line
connections. 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 four households
within the 1/2 mile compliance buffer do not have public water. 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. Fiber optic markers were also not observed during the drive -by. Aboveground electric
was observed and therefore not considered an impediment to service line installation.

3.3 OTHER CONSIDERATIONS
Chatham County is a rural water system who owns the infrastructure, manages the water supply, and meters and bills for water
use. The Cape Fear Steam Station vicinity is part of the Chatham County North Water System, which sources its potable water
from Lake Jordan.
Chatham County estimates the water pressure in the area to be approximately 75 psi, which is more than adequate for
residential domestic service. Chatham County has confirmed their capacity to serve the residents around Cape Fear. Therefore
based on this preliminary information, the flow capacity and pressure is deemed adequate to serve the four households in the
1/2 mile compliance buffer.
Since there will be four new service connections to an existing waterline, there is no anticipated impact on disinfection residual
concentration or water quality. Therefore addition of disinfection boosting or automatic flushing is deemed not required.

4. Regulatory Permitting
Since there is no waterline extension associated with this station, North Carolina permits for Encroachment Agreements,
Erosion and Sedimentation Control, and Public Water Supply are not applicable.
Dewberry® Duke Energy 1 Cape Fear Station Phase 11 Potable Water Programmatic Evaluation 19

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 installation of four new service line connections from an existing waterline.
Formal design documentation and construction bid phase is deemed unnecessary. The service line installation would be
performed in accordance with existing Chatham County procedures and standards. The schedule indicates an end date of May
2017 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 $76,000, which equates to
approximately $i9,000 per household. A 10% contingency is included.
The Phase II opinion of probable cost includes individual allocations for the service connection lines and meters (items 18
through 25) that equates to approximately $16,000 per new connection. We arrived at that allocation as follows:
For items 18 and 19 the service line lengths were measured for each household using the Phase II sheet mapping. Item 20
is for miscellaneous fittings associated with the service line connections.
For items 21 and 22 the meter/meter box allowance was developed from vendor quotations and from recent bid tabs we
have for similar projects.
Item 23 is for road crossings where the connection to be served is on the opposite side of the road from the water line.
Items 24 and 25 represent site costs associated with approximately 2,500 feet of new service line piping.
