The Order Accepting Surrender and Dismissing Application for Subsequent License was
issued by the Federal Energy Regulatory Commission (FERC) on July 19, 2007. A
subsequent Order on Rehearing and Clarification was issued on April 22, 2008. These
Orders accepted an application made by Duke Energy Carolinas, LLC (Duke) to remove
the Dillsboro Dam, located on the Tuckasegee River in Jackson County, NC. In ordering
Paragraph 50 (D) of the Order Accepting Surrender and Dismissing Application for
Subsequent License, the FERC required Duke:
At least 60 days before starting removal of the project works, the licensee shall
submit one copy of the following documents to the Commission's Division of Dam
Safety and Inspections (D2SI) Atlanta Regional Office, and two copies to the
Commission (one of these shall be a copy to the Director, D2SI): (1) a detailed
description of the sequence of activities and schedule for removing the project
features and restoring the site; (2) final contract plans and specifications; (3)
Quality Control and Inspection Program; (4) Temporary Construction
Emergency Action Plan; (5) a blasting plan, if necessary; (6) a public safety plan
for the period during removal activities; and (7) a detailed erosion and sediment
control plan that includes but is not limited to descriptions and locations of the
erosion and sediment control measures to be implemented during removal of the
project features and site restoration, to also include deconstruction staging areas,
access locations, and sediment and debris disposal areas.
The detailed activities presented here and in the associated attachments fulfill items 1-4
and 6 above and provide the detailed removal/demolition specifications and drawings

4.0 DAM AND POWERHOUSE REMOVAL PLAN
The decommissioning of the Project includes the full removal to grade of the existing
Dillsboro Dam and Powerhouse on the Tuckasegee River. A plan view and cross-section
view of the dam and powerhouse are shown in Figure 3. 1.1 and Figure 3.1.2. The dam
and powerhouse are to be removed to the original riverbed over the full width of the river
and no natural rock ledge will be removed. The river will be returned to its assumed pre-
dam bank-to-bank width and depth. In accordance with the Sediment Management Plan
and the Section 401/404 authorizations, the required 70,000 cubic yards of sediment will
be removed prior to demolition of the dam and subsequent drawdown of the reservoir.
Removal will be accomplished by use of hydraulic equipment to remove the dam and
powerhouse structures in accordance with a staged demolition plan. An excavator with a
hoe-ram attachment or similar mechanism will demolish the dam, with an excavator and
a track loader used to remove additional sediment, if necessary, and remove
rubble/concrete. There is no blasting associated with this demolition project. During the
demolition process, river flow will be, at various times and sometimes in combination,
passed through a notch in the dam, and/or passed over the partially demolished dam crest.
A complete hazardous material inventory will be conducted within the powerhouse prior
to demolition. Proper steps for the removal and disposal of discovered hazardous
material will be conducted in accordance with applicable state and federal regulations, as
well as Duke Energy standards. Upstream and downstream environmental monitoring
will also be conducted during the dam and powerhouse removal phase of the Project.
The existing transmission equipment, useable wood, powerhouse controls, and turbine-
generator equipment contained within and adjoining the powerhouse will be removed for
salvage purposes to the maximum extent possible.

Duke Energy Carolinas Dillsboro Dam Removal
Demolition Plan
4.1 Engineering analysis
The Dillsboro Dam and Powerhouse are to be removed to the original riverbed over the
full width of the river with no natural rock ledge to be removed. The dam consists of two
separate uncontrolled spillway sections and a gated section, and has an overall length of
approximately 230 feet. The concrete dam height is approximately 12 feet. The
powerhouse consists of a steel frame and wooden superstructure along with a three-unit
intake section. The overall powerhouse length is approximately 80 feet. The right
(north) abutment wall, approximately 10 feet long, and the left (south) abutment wall,
approximately 5 feet long, will be left in place during the demolition of the dam and
powerhouse. The respective abutment wall removal will be the last part of the dam
demolition and will occur just prior to site restoration.
The Dillsboro Dam and Powerhouse removal will consist of three demolition phases.
The first phase includes the removal of the powerhouse superstructure, removal of
generating equipment, and establishing water passage through the vacated hydro unit
openings and draft tubes. Consideration shall be given to salvaging as much of the
turbine-generator equipment as possible. The second phase consists of removing the
dam, and the third phase involves removal of the powerhouse substructure. Figure 3.2.1
and Figure 3.2.2 present diagrams of the dam and powerhouse removal sequence.
Powerhouse demolition access will be from the powerhouse parking lot off North River
Road (if possible), while access to the left (south) abutment will be off Mockingbird
Lane. An existing sewer line is located along the north reservoir rim and generally runs
parallel with the Dillsboro Reservoir and North River Road. The same sewer line
continues in a westerly direction downstream of the powerhouse. The sewer line will be
monitored during all phases of the demolition and removal. However, based on pre-
removal geotechnical studies, no sewer line issues are expected.
A detailed hazardous waste inspection/inventory will be conducted at the powerhouse
prior to Project demolition. The inventory will include all solvents, lubricants, paints,
6
Duke Energy Carolinas Dillsboro Dam Removal
Demolition Plan
oils, and the presence of asbestos and lead paint. The existing Dillsboro Spill Prevention,
Control, and Countermeasure Plan (or equivalent Oil Spill Response Manual) along with
existing plant Material Safety Data Sheets will be reviewed and utilized during the
inspection. The inventory shall include type and quantity of each substance.
A Hazardous Waste Removal & Disposal Plan will be developed for the Dillsboro
Project based on the inspection inventory. Potentially hazardous material will be
removed from the powerhouse prior to commencing powerhouse superstructure
demolition.
Mechanical sediment removal (i.e., hydraulic removal) will be conducted upstream of the
dam along the left bank (looking downstream). This removal will be accomplished
through use of a backhoe or vacuum dredging. The upstream sediment volume within the
existing reservoir is estimated at approximately 100,000 cubic yards. The quantity of
sediment to be mechanically removed is equal to 70,000 cubic yards, as detailed in the
Sediment Management Plan and required by the Section 401/404 authorizations. Once
removed this material will be properly disposed of in an upland disposal site or sold for
use on upland sites. Items 50(D) (2 through 7) of the FERC Surrender Order have been
submitted under a separate cover and provide the detailed removal/demolition
specifications and drawings.
A Section 401 (Clean Water Act) Water Quality Certification was issued from the
NCDWQ on November 27, 2007. A U.S. Army Corps of Engineers, Section 404 "dredge
and fill" permit (i.e., Nationwide Permit 27 and 16) was also required for this work
within the "waters of the U. S." This nationwide permit was authorized on June 5, 2008.
Other items required by the FERC Order or the Section 401 and approved for this project
include:
¦ Site Restoration Plan-50 (E) of the FERC Order
¦ Mussel Relocation Plan -50 (F) of the FERC Order
¦ Bat Relocation Plan - 50 (G) of the FERC Order
¦ Sediment Management Plan - 50 (H) of the FERC Order

4.2 Powerhouse superstructure removal
The powerhouse superstructure and machinery are to be removed prior to the start of dam
removal activities. The estimated duration of powerhouse removal is 4 to 5 weeks.
4.3 Dam removal
The crest of the 12-foot-high dam is at elevation 1972.0 feet msl. The dam is 230 feet
wide, including a 34-foot-wide gate and overflow spillway structure at the left (south)
abutment of the dam. Dam demolition will begin during the mid-winter to early spring
months (i.e., January to late March/early April 2010).
4.4 Powerhouse substructure removal
The removal of the powerhouse concrete substructure will be performed after completing
the majority of the dam removal phase. The substructure depth is approximately 23 feet.
The estimated duration of removal is 4 to 5 weeks.

1.2 Background
The Dillsboro Hydroelectric Project is located in western North Carolina on the Tuckasegee
River near the town of Dillsboro, at River Mile 31.7, in Jackson County, NC. Duke owns
and operates the Dillsboro Hydroelectric Project in a limited storage mode. The project has
an installed capacity of 225 kW.
The project's reservoir is filled to near capacity with an estimated 100,000 to 120,000 cubic
yards of sediment. Channel depths for about 500 feet upstream of the powerhouse range from
8 to 12 feet. Most of the remaining portions of the reservoir are 3 to 7 feet deep. Historically,
Duke has operated the project in a run-of-river mode, maintaining the headpond within 6
inches of full pond elevation. Project operation depends on available now in the Tuckasegee
River, which is regulated by Duke's upstream East Fork and West Fork projects (Project
Nos. 2698 and 2686, respectively).
The Order Accepting Surrender and Dismissing Application for Subsequent License were
issued by FERC on July 19, 2007. A subsequent Order on Rehearing and Clarification was
issued on April 22, 2008. These Orders accept an application made by Duke to remove the
Dillsboro Hydroelectric Project. In ordering paragraph (D) of the Order Accepting Surrender
and Dismissing Application for Subsequent License, the FERC requires Duke to provide "a
detailed description of activities and schedule for removing the project features and restoring

concrete piers, and steel flood gates.
The Dillsboro Dam is a concrete masonry structure that is about 310 feet in length and 12
feet high. Major components of the Dillsboro Dam are listed below, beginning at the left
abutment (facing downstream). All elevations are referenced in U. S. Geological Survey
(USGS) datum and are expressed in feet above mean sea level (MSL). Main components
of the dam include:
• A concrete, non-overflowing section with a crest elevation of 1978.2 feet above
MSL.
• An uncontrolled 14 foot-wide spillway section with a crest elevation of 1972.0

• A 197-foot uncontrolled spillway with a crest elevation of 1972 feet above MSL.
• A 64.5-foot wide powerhouse with a wood/timber superstructure and concrete
substructure.
• An 80-foot long intake section.
• A concrete, non-overflowing section with a crest elevation of 1980 feet above
MSL.
The powerhouse consists of a 64.5-foot wide reinforced concrete substructure and a
wood/steel superstructure. Inside the powerhouse are two generating units. The unit
closest to the open spillway, Unit No. 1, consists of an S. Morgan Smith vertical Francis-
type turbine rated at 276 horsepower (hp) under 12-foot of head and 225 revolutions per
minute (rpm) connected to a 219 kilovolt-ampere (kVa) Westinghouse generator at 0.80-
power factor and a DC exciter. Unit No. 2 has a Leffel Type - Z turbine rated at 44 hp
under 12-foot of head and 200 rpm connected to a 62.5 kVa General Electric generator at
0.80-power factor and a DC exciter. Each unit has an open pit concrete penstock. The
rated hydraulic capacities of the turbines are 190 cubic feet per second (cfs) for Unit No.
1 and 44 cfs for Unit No. 2.
1.3.2 Description of Construction
The decommissioning of the Project includes the full removal to grade of the existing
Spillway and partial removal of the Powerhouse. The dam is to be removed to the
original riverbed over the full width of the river and no rock ledge will be removed. The
powerhouse superstructure will be removed completely and the substructure will be
partially removed. The river will be returned to its assumed pre-dam bank-to-bank width
and depth.
Removal will be accomplished by use of hydraulic equipment to remove the dam and
powerhouse structures in accordance with a staged demolition plan. An excavator with a
hoe-ram attachment or similar mechanism will demolish the dam, with an excavator and
a track loader used to remove remaining sediment, if necessary, and remove
rubble/concrete. Additionally, mechanical sediment removal will be performed in the
forebay area to help conduct flows during the demolition process. During the demolition
process, river flow will be diverted through a notch in the dam, and/or passed over the
partially demolished crest.
To provide stability of the embankment along the river at the powerhouse, the
powerhouse basement slab and walls on the embankment will be evaluated during
construction to determine if they can be left in place. However, if the structures are
removed a slope stabilizing system shall be installed to support embankment.
Refer to the project schedule for more details.

Only one log book should be maintained by the Construction Manager at one time.
Completed log books should be filed in the project files. The log books are important
documents and are often used in settlement of disputes, to reconstruct events after the fact.
Entries should be made in the log book on a daily basis while the subject matter is fresh in
the author's mind.
4.2 Nonconformance Reports
A Nonconformance Report (NCR) and procedure have been developed to provide a standard
document format and procedure for communicating with the General Construction
Contractor regarding demolition quality nonconformance and required corrective action. A
nonconformance is defined as a deficiency in characteristic, documentation, or procedure
which renders the contractor's work unacceptable with respect to the quality requirements of
the contract documents. A NCR form is presented in Appendix D.
A NCR shall be issued to the General Construction Contractor when he presents any portion
of his work as complete and a serous deficiency exists or a deficiency trend is occurring in
subsequent similar work. NCRs are not to be utilized for documenting contractor
acknowledged incomplete "Punch List" type work items or for problems relating to project
design.
The Construction Manager is responsible for initiating NCRs. The NCRs shall be numbered
sequentially and filed in accordance with Duke's Record Keeping Procedures. The NCRs
shall be reviewed weekly by the Construction Manager to determine contractor compliance
with corrective action requirements and identify the need for any follow-up action. In the
event of contractor failure to comply with the corrective action requirements of a NCR, either
unsatisfactory work or failure to meet the time requirements, the following procedure will be
implemented.
• The Construction Manager and Project Manager shall jointly prepare a formal
contract correspondence letter with a copy of the original NCR attached advising
the contractor of his failure to meet the corrective action requirements;
• The letter will establish a date for when the corrective action must be
satisfactorily completed and state that in the event of contractor failure to
satisfactorily complete the corrective action by this date, the corrective action
work will be performed by others with all associated costs being applied to his
contract;
• The letter shall state any other actions that Duke may take under the terms of the
contract as a result of failing to resolve the NCR;
• Copy distribution of all such follow-up NCR correspondence shall be the same as
the original NCR and shall be filed in the appropriate NCR file.

operates the Dillsboro Hydroelectric Project in a limited storage mode. The project has an
installed capacity of 225 kW.
The project's reservoir is filled to near capacity with an estimated 100,000 to 120,000 cubic
yards of sediment. Channel depths for about 500 feet upstream of the powerhouse range from 8
to 12 feet. Most of the remaining portions of the reservoir are 3 to 7 feet deep. Historically, Duke
has operated the project in a run-of-river mode, maintaining the headpond within 6 inches of full
pond elevation. Project operation depends on available flow in the Tuckasegee River, which is
regulated by Duke's upstream East Fork and West Fork projects (Project Nos. 2698 and 2686,
respectively).
The Order Accepting Surrender and Dismissing Application for Subsequent License were issued
by FERC on July 19, 2007. A subsequent Order on Rehearing and Clarification was issued on
April 22, 2008. These Orders accept an application made by Duke to remove the Dillsboro
Hydroelectric Project. In ordering paragraph (D) of the Order Accepting Surrender and
Dismissing Application for Subsequent License, the FERC requires Duke to provide "a detailed
description of activities and schedule for removing the project features and restoring the site."
The detailed activities schedule provided covers the removal of all project features through site
restoration and has been developed in consultation with the North Carolina Division of Water
Quality, North Carolina Division of Water Resources, North Carolina Wildlife Resource
Commission, U.S. Fish and Wildlife Service, North Carolina Department of Environmental and
Natural Resources, and the Eastern Band of Cherokee Indians. The removal is scheduled to be

removed during the mid-winter to early spring months (i.e. December to March time period) in
accordance with Application for Surrender of License (Duke Energy 2004).
The decommissioning of the Project includes the full removal to grade of the existing Spillway,
piers, and gate; along with the partial removal of the Powerhouse structure. The Spillway is to
be removed to the original riverbed over the full width of the river and no rock ledge will be
removed. There will be a partial removal of the Powerhouse structure. The river will be
returned to its assumed pre-dam bank-to-bank width and depth.
Removal will be accomplished by use of hydraulic equipment to remove the dam and
powerhouse structures in accordance with a staged demolition plan. An excavator with a hoe-
ram attachment or similar mechanism will demolish the dam, with an excavator and a track
loader used to remove sediment, if necessary, and remove rubble/concrete. Additionally,
mechanical sediment removal will be performed in the forebay area to help conduct flows during
the demolition process. During the demolition process, river flow will be diverted through a
notch in the dam, and/or passed over the partially demolished crest.

1. INTRODUCTION
This report has been prepared in accordance with the March 1992, "Guidelines For Public Safety
at Hydropower Projects" published by the Federal Energy Regulatory Commission's (FERC)
Division of Dam Safety and Inspections.
1.1 Purpose
Duke Energy Carolinas, LLC (Duke) intends to decommission the Dillsboro Hydroelectric
Project (FERC No. 2602) located in Western North Carolina on the Tuskasegee River.
Based on the FERC Order, Duke Energy of Carolinas, LLC (Duke) is required to submit a
Public Safety and Traffic Control Plan for operations during the decommissioning of the
Hydroelectric Project.
1.2 Background
The Dillsboro Hydroelectric Project is located in Western North Carolina on the Tuckasegee
River near the town of Dillsboro, at River Mile 31.7, in Jackson County, NC. Duke owns
and operates the Dillsboro Hydroelectric Project in a limited storage mode. The project has
an installed capacity of 225 kW.
The project's reservoir is filled to near capacity with an estimated 100,000 to 120,000 cubic
yards of sediment. Channel depths for about 500 feet upstream of the powerhouse range from
8 to 12 feet. Most of the remaining portions of the reservoir are 3 to 7 feet deep. Historically,
Duke has operated the project in a run-of-river mode, maintaining the headpond within 6
inches of full pond elevation. Project operation depends on available now in the Tuckasegee
River, which is regulated by Duke's upstream East Fork and West Fork projects (Project
Nos. 2698 and 2686, respectively).
The Order Accepting Surrender and Dismissing Application for Subsequent License were
issued by FERC on July 19, 2007. A subsequent Order on Rehearing and Clarification was
issued on April 22, 2008. These Orders accept an application made by Duke to remove the
Dillsboro Hydroelectric Project. In ordering paragraph (D) of the Order Accepting Surrender
and Dismissing Application for Subsequent License, the FERC requires Duke to provide "a
detailed description of activities and schedule for removing the project features and restoring
the site." The detailed activities schedule provided covers the removal of all project features
through site restoration and has been developed in consultation with the North Carolina
Division of Water Quality, North Carolina Division of Water Resources, North Carolina
Wildlife Resource Commission, U.S. Fish and Wildlife Service, North Carolina Department
of Environmental and Natural Resources, and the Eastern Band of Cherokee Indians. The
removal is scheduled to be removed during the mid-winter to early spring months (i.e.

2. SCOPE
2.1 Staged Demolition
The project will be completed in the following three stages:
• Stage 1: This phase includes the removal of the powerhouse superstructure,
removal of generating equipment, and establishing water passage through the
notch removed in Spillway. Consideration shall be given to salvaging as much of
the turbine-generator equipment as possible.
• Stage 2: The second phase consists of removing the dam, pier and gate structures.
• Stage 3: The third and final phase involves the partial removal of the powerhouse
substructure.
To provide stability of the embankment along the river at the powerhouse, the training walls
and powerhouse basement wall will be evaluated during demolition to determine if they can
be left in place. However, if the structures are removed a slope stabilizing system shall be
installed to support embankment.
The Dillsboro Hydroelectric Project is to be decommissioned and removed to restore the
Tuckasegee River back to the original riverbed over the full width of the river and rock
ledges will not be removed. The following sections will explain the type of structures
present and demolition to be anticipated.
The main access to the demolition site will be at the intersection of Mockingbird Lane and
Monroe Buchanan Road. Access will also be necessary from North River Rd during the
demolition of the Powerhouse structure.
2.2 Type of Structures to be Demolished
The Dillsboro Hydroelectric Project consists of a Powerhouse, spillway overflow dam, piers,
and gates.
The Dillsboro Spillway is a concrete masonry structure that is about 310 feet in length and 12
feet high. Major components of the Dillsboro Dam are listed below, beginning at the left
abutment (facing downstream). All elevations are referenced in U. S. Geological Survey
(USGS) datum and are expressed in feet above mean sea level (MSL). Main components of
the dam include:
• A concrete masonry, non-overflowing section with a crest elevation of 1978.2 feet
above MSL;
• An uncontrolled 14 foot-wide spillway section with a crest elevation of 1972.0
feet above MSL;
• A 20-foot wide spillway section with two six foot wide spill gates. The gates sill
elevation is at 1961.0 feet above MSL;

Revision No.: Review 2
Issue Date: 12118108
• A 197-foot uncontrolled spillway with a crest elevation of 1972 feet above MSL;
• A 64.5-foot wide powerhouse with a brick and concrete superstructure and
concrete substructure;
• An 80-foot long intake section;
• A concrete masonry, non-overflowing section with a crest elevation of 1980 feet
above MSL.
The powerhouse consists of a 64.5-foot wide reinforced concrete substructure and a
wood/steel superstructure. Inside the powerhouse are two generating units. The unit closest
to the open spillway, Unit No. 1, consists of an S. Morgan Smith vertical Francis-type turbine
rated at 276 horsepower (hp) under 12-foot of head and 225 revolutions per minute (rpm)
connected to a 219 kilovolt-ampere (kVa) Westinghouse generator at 0.80-power factor and a
DC exciter. Unit No. 2 has a Leffel Type - Z turbine rated at 44 hp under 12-foot of head
and 200 rpm connected to a 62.5 kVa General Electric generator at 0.80-power factor and a
DC exciter. Each unit has an open pit concrete penstock. The rated hydraulic capacities of
the turbines are 190 cubic feet per second (cfs) for Unit No. 1 and 44 cfs for Unit No. 2.
2.3 Description of Demolition
The decommissioning of the Project includes the full removal to grade of the existing
Dillsboro Spillway and partial removal of the Powerhouse structures. The Spillway is to be
removed to the original riverbed over the full width of the river and no rock ledge will be
removed. The Powerhouse superstructure will be completely removed with a partial removal
of the substructure. The river will be returned to its assumed pre-dam bank-to-bank width
and depth.
Removal will be accomplished by use of hydraulic equipment to remove the dam and
powerhouse structures in accordance with a staged demolition plan. An excavator with a
hoe-ram attachment or similar mechanism will demolish the spillway, with an excavator and
a track loader used to remove sediment, if necessary, and remove rubble/concrete.
Additionally, mechanical sediment removal will be performed in the forebay area to help
conduct flows during the demolition process. During the demolition process, river now will
be diverted through the notch in the dam, and/or passed over the partially demolished crest.
3. HAZARDOUS FEATURES AT PROJECT
The two main areas that will be impacted by the demolition are the powerhouse area and
upstream and downstream areas of the river near the spillway & gate sections of the dam. In the
area of the powerhouse, the powerhouse basement walls could become unstable during
demolition.
Also, the roadways on either side of the river will be impacted either by drivers having their
attention diverted away due to the ongoing demolition activities and/or construction traffic
entering/exiting at Mockingbird Lane and on North River Rd.

4. PUBLIC SAFETY MEASURES
The following public safety measures are planned and will be undertaken based on the
characteristics of the project location, the high public use of the immediate area the nature of the
decommissioning work.
4.1 Public Awareness and Information
Information about demolition activities will be provided to local organizations to distribute to
the public. Also, signage along the roadways will be provided to warn and inform the public
of potential hazards being approached. Also, signage with lighting for nighttime visibility
will be posted up and downstream along the river to warn and inform the boaters and
canoeist of potential hazards being approached. Furthermore, the signs along the river shall
inform canoeists and kayakers required portage around the dam.
4.2 Barriers & Fencing to Protect the Public
4.2.1 Spillways & Overflow Gates
Due to the high recreational use of the river, boat barriers or buoys will be utilized to
keep boaters and canoeist out of the construction areas. Also signs will be place
upstream to warn the public of demolition activities and dangers as previously discussed.
4.2.2 Powerhouse Area
Due to the powerhouse's close proximity to North River Road all construction traffic will
enter the site from Mockingbird Lane as shown in Figure 2, except during Powerhouse
structural demolition. A temporary fence will be required to keep the public from
entering the demolition site along North River Road. Also, the demolition staging and
access area (off of Mockingbird Lane) shall be secured as well to keep the public from
entering from this location.
4.3 Lights on for Safety
Project vehicle lights will be illuminated during all hours of operation for safety and
visibility.
4.4 Traffic Control
In addition to public awareness and intelligently scheduling work around peak hours of
operation for the access roads, a plan for safely controlling traffic is a major component of
this public safety plan. Section 5 discusses the Traffic Control Plan for this project.

North Carolina Department of Transportation 511 Traveler Information System will be used
to inform the traveling public of conditions and delays that might result on the roads
indicated herein as a result of this project.
5.2 Work Zone Standards
Traffic controls in work zones will meet the requirements of the MUTCD. Traffic control
personnel will be trained and experienced individuals in construction traffic control.
5.3 Temporary Traffic Control Plan
A temporary traffic control plan will be used periodically as activities at the powerhouse and
dam removal areas require in accordance with MUTCD standards and North Carolina
Supplement indicated herein.
5.4 Work Coordination and Safety Meetings
In order to reduce or avoid impacts to traffic and in the interest of public safety, the
contractor will conduct each morning a briefing with all project workers to review and
coordinate the days activities, to conduct a safety briefing specific to that day's work
activities and to plan ahead for activities that will impact traffic as well as the safety of the
traveling public and project personnel working on-site.
5.5 Worker Safety and Training
Project personnel will receive awareness training on how to work next to motor vehicle
traffic in a way to promote their personal safety and that of the traveling public. Workers
will wear high-visibility safety vests when working around operating demolition equipment
and while in or near the roads named herein.
