Weatherspoon Proposed Permanent Water Solution_20161202

Permanent Water Supply Proposal to DEQ - Weatherspoon
Weatherspoon Steam Station
Robeson Counties
14 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) business 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 seven (7) eligible well owners near Weatherspoon be offered the option of a connection to a
public water supply or the installation of a water treatment system, and seven (7) households
located on Taylor Drive (identified as parcels 23, 37, 54, 81, 93, and 96 in the Dewberry
evaluation) be offered a water treatment system.
The City of Lumberton has an existing service line along NC 72 Hwy (S. Roberts Ave), where
parcels 15 and 60 are located. Robeson County has existing service lines along Old Whiteville
Road and Beulah Church Road. All of the households recommended for connection to a public
water supply are located along a current water main and therefore only service connections are
required. Service lines connections range from approximately 225 feet along NC 72 Hwy to
approximately 1,200 feet for the household on Havahiah Drive (off of Beulah Church Road).
A water treatment system is being recommended for the seven households located off of Taylor
Drive. While Robeson County did not indicate any issues related to water quality with running a
municipal line to these households, the cost to run the line just to these households is estimated
at $553,000, or $79,500 each. The elevated costs are due to the new water main required for
these households. The cost estimate indicates that running the line to these households is cost
prohibitive. Total costs shown in the table below exclude costs associated with running a public
water supply line to the households off of Taylor Drive; therefore, the costs below are different
than the costs included in Appendix D of the Dewberry evaluation.
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 seven (7)
households is approximately $277,000, or $39,600 for each household. While this cost estimate
is greater than the $35,000 for each household threshold agreed upon between Duke Energy
DUKE
`C ENERGY,

Permanent Water Supply Proposal to DEQ - Weatherspoon
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 the City of Lumberton or Robeson County 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 the City of Lumberton and Robeson County, and an evaluation of
the system by Dewberry, flow and water pressure are adequate to service the households
recommended for connection to the systems.
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.
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 May 2018, which meets the October 15, 2018 deadline in HB630. If
NCDEQ agrees with Duke recommendation to provide the option of public water connections to
those households where only a service line is required, the schedule may be accelerated.
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 September 7, 2016 a project review meeting was held at the Robeson County Administration Building in Lumberton, NC.
Representatives from Duke Energy, Dewberry, and Robeson County attended the meeting. Additionally, Dewberry and the City
of Lumberton had several phone and email communications in July and November of 2016.
Detailed Phase II mapping was developed using Robeson 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 September 7, 2016.
A household database was developed using Robeson 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 line in
the public road right of way or along private roads using conventional construction methods. Easements appear to be required
in seven areas.
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 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 14 households within the 1/2 mile compliance
buffer. The 14 households are served from 13 water line connections as one parcel had more than one household per
connection. The estimated costs are summarized below:
TODewberry Duke Energy Weatherspoon 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 14 households will receive potable
water service.
This report provides additional detail on the Project Approach, Basis of Design, and Site Analysis. Weatherspoon Steam
Station mapping is provided in Appendix A. The household database is provided in Appendix B. The Weatherspoon Steam
Station Potable Water Schedule is provided in Appendix C, and the Opinion of Probable Cost is provided in Appendix D.

1. Introduction and Project Approach
PROJECT INTRODUCTION
During the Phase I programmatic potable water evaluation desktop study, concept level mapping was developed showing the
Weatherspoon 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. (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 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 Weatherspoon 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 line 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 line 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 meetings with Robeson County and the City of Lumberton.
On September 7, 2o16 a project review meeting was held at the Robeson County Administration Building in Lumberton, NC to
discuss execution of this Phase II preliminary evaluation and subsequent project execution. Representatives from Duke
Energy, Dewberry, and Robeson 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.
Following the meeting, Dewberry performed a drive -by observation of the potable water pipe route. Additionally, Dewberry
and the City of Lumberton had several phone and email communications in July and November of 2016.
During Phase I Dewberry obtained municipality mapping of the potable water distribution system and then developed draft
maps showing the Weatherspoon 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 Robeson 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
Robeson County and the City of Lumberton 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 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 Weatherspoon 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.
Private easements will be required in seven areas.
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 on the cost estimate shows 8 inch C-goo PVC for the potable water line pipe. The 8 inch diameter is considered a
conservative pipe size to meet the water demand of the households within the compliance buffer.
The 8 inch water line pipes are sized to meet fire flow as that is required for potable service by Robeson County.
Items 1 through 8 on the cost estimate show material cost for the piping, valves, and associated fittings. The sum of Items
1 through 8 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 Weatherspoon 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 21-22 on the cost estimate indicates there are 13 potable water line connections. The four 2
inch service taps are for service connections exceeding i,000 feet or parcels with multiple connections. The nine 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 Robeson County property maps and drive -by
observations.
Items g through 17 and 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. 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 and service lines installed down private roads
and/or across private property.
TODewberry Duke Energy Weatherspoon Station Phase 11 Potable Water Programmatic Evaluation 6

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 Robeson County and City of
Lumberton potable water supply systems, indicating that just over a 1/2 mile (~2,goo LF) of new potable water piping is
required to serve households within the 1/2 mile compliance buffer.
The City of Lumberton will own and operate the service lines to the two parcels on NC-72E (Parcels 15 and 6o). Robeson
County will own and operate the expanded potable water system off Old Whiteville Rd, which will require a private easement,
and the remaining 11 service lines east of NC-72E.
The Phase II Site map and sheets in Appendix A were prepared by overlaying Robeson 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 five rectangular property map sections. Five sheets
were then prepared that show the water line route, individual households, and household service line connections within the
1/2 mile compliance buffer. During the September 7, 2o16 drive -by, Dewberry visually observed households shown in the
Appendix A sheet mapping.
The household database in Appendix B was created from the Robeson 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 one parcel 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.
Review of the mapping from Appendix A allowed for estimates of the required private easement areas around the Steam
Station. The potable water line proposed to serve residents around the Weatherspoon Steam Station will require private
easement acquisition in seven areas. Typical municipal easement standards were followed around the Weatherspoon 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 50% of the average land value (per acre) as indicated by public tax assessment for properties around the
Weatherspoon 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 proposed water line piping will be installed along state roads, where possible. During the
September 7, 2016 drive -by Dewberry did not observe above grade conflicting physical features that will have a significant
impact on the construction cost or schedule, with the exception of one railroad crossing. The railroad crossing is an at -grade
non -signalized crossing and is located at the end of Taylor Drive. Taylor Drive is a non -paved (dirt) drive that extends across
the railroad to provide access for three households. The water main crossing underneath the railroad will require bore and jack
installation of a steel carrier pipe extending the full width of railroad right-of-way.
Based on our observations and the Phase II mapping, it appears to be technically feasible to install the potable water line in the
public road right of way or along the side of private roads using conventional construction methods, such as an open trench
TODewberry Duke Energy Weatherspoon Station Phase 11 Potable Water Programmatic Evaluation 7

with pipe bedding material. Approximately five service line road crossings will be required with one water line road crossing
anticipated. 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 line 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 14 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 water line installation.
Dewberry observed the public road right-of-way and private road widths and evaluated the feasibility to install the proposed
water line 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 line installation challenging but not overly complicated. In some areas it
may be necessary to conduct subsurface utility evaluation and route the water line 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 line easement, or the construction impact is accounted for in the cost estimate as a
renovation allowance.
3.3 OTHER CONSIDERATIONS
Robeson County owns the infrastructure, manages the water supply, and meters and bills for water use. Robeson County
sources their potable water from 54 production wells, located outside the 1/2 mile compliance buffer, and 13 water treatment
plants throughout the County, producing approximately 15-17 MGD.
Robeson County estimates the water pressure in the area to be approximately 55 psi, which is more than adequate for rural
residential domestic service. Robeson County has confirmed their capacity to serve the residents around Weatherspoon.
Therefore based on this preliminary information, the flow capacity and pressure is deemed adequate to serve the 12
households in the 1/2 mile compliance buffer that will be served by the county.
Based on information from Robeson County, the water age in the Weatherspoon area is approximately 1- 5 days, dependent
upon location. 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 extension, as
planned by Dewberry, utilizes the minimal diameter pipe for service, based upon the County standards, and considers system
flushing to be required in this area. The proposed water system extension for 12 households will marginally increase the water
age. Robeson County has considered the increase in water age and they think the water quality will be maintained.
The City of Lumberton owns the infrastructure, manages the water supply, and meters and bills for water use. The City of
Lumberton sources their potable water from the Lumber River and seven supplemental wells, located outside the 1/2 mile
compliance buffer, with the ability to supply approximately 16 MGD.
The City of Lumberton has confirmed their capacity to serve the residents around the Weatherspoon Steam Station. Therefore
based on this preliminary information, the flow capacity and pressure is deemed adequate to serve the two households in the
1/2 mile compliance buffer to be served by the City.
TODewberry- Duke Energy Weatherspoon Station Phase 11 Potable Water Programmatic Evaluation 8

Since there will be two 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
The water line 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 Weatherspoon 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
• Railroad Pipeline Occupancy Agreement
TODewberry Duke Energy Weatherspoon Station Phase 11 Potable Water Programmatic Evaluation 10

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 May 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 $830,000, which equates to
approximately $59,000 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 18
through 25) that equates to approximately $14,500 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 6,500 feet of new service line piping.
