products for this project.
Vibra Tech — will provide vibration monitoring and consulting.
Furukawa Rock Drills — will provide drill maintenance, service, and repairs.
Morgan Corp. — will provide drill mobilization/demobilization, along with drill

Project Coordination Schedule
Drilling, Blasting, and Monitoring operations will be directed and coordinated by Palmetto
Rock Services Project Manager/Lead Blaster, Chris Broom, and Superintendent/Blaster,
Travis Childers. Palmetto Rock Services, Inc. hereinafter abbreviated to "PRS" (See
Exhibit 5 for PRS licensing) will provide drilling and blasting services and will be
responsible for drill logs, blast plans, and blast records. Chris Broom will be PRS's Blaster
of Record.
PRS will implement the following Blasting Work Plan and procedures to accomplish the
Scope of Work, and to ensure the safety of people and property during the time leading
up to, during, and immediately following the use of explosives on this project. This plan
will be systematic and follow the below sequence for the project:
1- Morgan Corp. will clear and prepare designated area for drilling and blasting.
2- During excavation activities, seismograph installation and Pre -Blast Surveys if
required will be done for all structures identified by Duke Energy to document
the existing conditions of these structures.
3- Morgan Corp. surveyors will provide all layout staking, elevations, and depth
for all drill holes and drill patterns.
4- Blast Patterns will vary depending upon rock layout, location and depth. Typical
mass blast patterns are 7' x T with a blast -hole diameter of 3.50".
5- The blast will be executed and monitored. (See Blast Safety Protocol below)
6- Blast records if required will be submitted 1 business day after a blast Morgan
Corp.and Duke Energy. (See Exhibit 3 for Blast Record Forms)

Blasts will take place on an as needed basis and will typically be performed at noon.
Morgan Corp. will provide all flagging and control all accesses in support of these
operations.
Furukawa hydraulic rock drills will be used for this project. Drill logs will be kept for each
hole that will identify and record any voids or soft seams that may be in the rock and their
elevations Drill rate of penetration, cuttings, and driller experience will be used to record
voids. Shots will be designed using recommendations from the "International Society of
Explosives Engineer's Handbook", Chapters 31 thru 33 and "The National Fire Protection
Association (NFPA) Materials Code", Chapters 10 and 11. Blast designs will meet the
vibration standards enforced by the State of North Carolina (Z Curve).
The Standard is defined in USBM RI 8507. Non -electric Detonators will be used in the
blast -holes and a nonelectric lead-in line will be used to connect the shot to the starter
which will initiate detonation. Loading poles used during the loading of explosives will be
made of wood with non -sparking connectors. Explosives will be transported to the site the
day of blast and all unused excess explosive material will be removed from site.
Explosives will be transported per local and federal regulations.
Specialty subcontractor Elite Blasting Services will be providing and delivering the
explosives for this project.
Storage of explosives is regulated under the U.S. Bureau of Alcohol, Tobacco, Firearms,
and Explosives (See Appendix 5 for PRS's Federal Explosive License and the attached
ATF Regulations which can also be found at www.atf.gov). Transport of explosives is
regulated under the U.S. Department of Transportation Federal Motor Carrier Safety

Administration. These regulations can be found at www.fmcas.dot.gov. Additional
information can be found at www.nfpa.org. Once explosives reach the site and are to be
used, they are under the control of the Blaster -In -Charge. (See Appendix 5 for PRS's
employee blasters license, issued by the State of South Carolina). North Carolina does
not require the blaster in charge to obtain a blasting license, but does require individuals
to be qualified by reason of training, knowledge, or experience. The qualifications can be
found www.labor.nc.gov blasting and explosives (13 NCAC 07F .0704). The state of
South Carolina requires continued education to renew license each year and identifies
qualified blasters within PRS.
Blasting operations will be performed in accordance with OSHA 29 CFR 1926, Subpart U
— Blasting and Use of Explosives and 29 CFR 1910.109 — Explosives and Blasting
Agents. Transportation of explosives will be performed in accordance with DOT 49 CFR
Subtitle B — Other Regulations Relating To Transportation and IME 22 —
Recommendations for the Safe Transportation of Detonators in a Vehicle with Certain
other Explosives.
PRS will hire a specialty contractor who will provide seismic and air overpressure monitoring.
Pre -blast surveys of locations specified by Duke Energy will be conducted.

Blast Safety Protocol
Palmetto Rock Services, Inc. will implement the following safety protocol for blasting
operations and complete the Daily Blasting Checklist (see Exhibit 1).
1- Prior to start of blasting, signs will be posted in front of entrances to the
project. These signs will read:
a. Danger -Blasting Area
b. Blasting Signals —
Five minutes before blast — five long tones
One minute before blast — five short tones
All clear — One long tone
2- Flag men will be placed 500 feet from the Blast Area and close any
construction access roads prior to detonation signals and this will be
confirmed before detonation signal sequence begins.
3- Five minutes before detonation a signal consisting of five consecutive
soundings of five seconds each will be done.
4- One minute before detonation a signal consisting of five consecutive short
soundings of one second each will be done.
5- The blast will be detonated.
Er Blast site will then be inspected for any misfires or live explosives.
7- Once it is determined there are no misfires or live explosives present a
single ten second sounding will be the "All Clear" signal.
8- Flag men will release traffic.

SSU 3000LC
The SSU 3000LC is a convenient, easy to use and complete
vibration and sound monitoring system designed with the user in
mind. Key features include an enhanced tactile keypad, heavy-
duty twist -lock metal cable connectors and a heavy -gauge
aluminum enclosure with baked enamel finish. The four -line by
20-character LCD and menu -driven programming makes on -site
setup easy and permits the user to view numerical waveform
data and monitoring results in the field. The timesaving
template utility can store repetitive setup information for quickly
deployed instruments with pre -defined configurations. The
internal lead -acid battery is long lasting and easily charged using
the included AC adapter. An integrated timer turns the unit on
and off at pre -selected times to conserve battery power. The 2-
hertz, high-pass microphone and all other accessories fit easily
into the tough, structural -resin carrying case.

The SSU 3000LC has three recording modes: 1) triggered -
either seismic or sound, 2) continuous (histogram) and
3) sustained trigger. The internal memory can store up to 220,
1-second events. Sustained trigger mode delays processing and
permits collection of consecutive 15-second intervals of
waveform data up to a cumulative total of approximately 4.2
minutes. Data can be collected in either imperial (US
customary) or metric units. The included basic compliance
software package can be used for data analysis and preparation
of standard or customized reports.
GeoSonics" is a leader in seismograph innovation, design,
manufacturing and vibration consulting. Because we use the
equipment we design, a user-friendly interface, ruggedness and
reliability are not just goals - they are standards.
GeoSonics ...always a step ahead!

Drilling and Blasting Safety
INTRODUCTION
Drilling and Blasting Job Hazard
Palmetto Rock Services, Inc. was formed in 1995 as a specialty subcontractor based in Spartanburg, South
Carolina to provide full service rock drilling and blasting services to the construction and mining
industries. Our original area of emphasis was North Carolina and South Carolina, but now encompasses
much of the Southeast. Our blasting professionals hold state blasting licenses in: Alabama, Florida,
Georgia, Kentucky, South Carolina, Tennessee, Virginia, and West Virginia. North Carolina does not
currently have state licensure for blasting.
Our mining experience includes contract drilling with at the Kennecott Ridgeway Gold Mine in Ridgeway,
S.C. and drilling and blasting services in two aggregate quarries located in Greenwood, S.C. and Jefferson,
Georgia. Our emphasis however, is construction drilling and blasting for all types of projects including
highway construction of new location roads and improvement projects of existing roads, power plants,
airport runways, taxiways and aprons, regional retail shopping malls, golf courses, landfills, subdivisions,
office buildings, assisted living communities, municipal and private utilities and manufacturing and
warehousing facilities. We perform work in both the public and private sector.
For all the accomplishments and successful projects we could list, our most cherished record and the issue
we take more seriously than anything is our impeccable safety record. Absolutely nothing we do comes
before the safety and well-being of our staff, the public at large, the companies we work with and for and
the places where we do our work. This is not only in the best interest of our business, it is our deep moral
and ethical obligation to take every prudent precaution necessary to insure the safety and well-being of
everyone exposed to the hazards of our industry. Rather than being the largest drilling and blasting
subcontractor in our region, we strive to be the best.
Palmetto Rock Services, Inc. is committed to providing a safe workplace for its employees and all others
at or near our work sites. Our goal is to conduct blasting operations in the safest manner possible while
minimizing the risk of injuries and damage to property. This blasting safety plan defines our company
policy regarding all work in which explosives are stored, transported, and used. This safety policy will
be communicated to our employees, contractors, and suppliers through on -site training and regular
safety meetings. These policies do not supersede any federal, state, or local regulations regarding
Page 1

110 PALMETTO ROCK
DRILLING & BLASTING
Analysis
Drilling and Blasting Safety
Drilling and Blasting Job Hazard
explosives and blasting work. Compliance with these policies and all applicable federal, state, and local
regulations will be strictly enforced.
2. BLAST SITE
Many policy guidelines refer to the "blast site." For the purposes of this safety plan, and federal regulations,
the blast site is defined as:
The area where explosive material is handled during loading including an area extending 50 feet in all
directions from loaded blast holes or explosive materials.
3. BLASTER -IN -CHARGE
The designated Blaster -In -Charge shall have complete authority over all personnel within the blast site and is
responsible for all blasting activities that occur at the project. The Blaster -In -Charge shall hold all required
blasting licenses, have appropriate experience and training, and generally be responsible for:
3.1. Maintaining an explosives storage and transportation system that is safe and in compliance
with all applicable regulations.

actions when necessary.
3.7. Ensuring that all appropriate blasting plans and reports are kept
and submitted as required by the project documents and regulatory agencies.
4. HAZARD AND RISK ASSESSMENT
The general and site specific blasting hazards and environmental impacts will be defined for each blasting
site. Blasting plans and procedures will incorporate all reasonable measures necessary to eliminate
negative impacts on persons, property, and the environment. The following general hazard areas shall be
reviewed to help identify potential site -specific hazards and controls for each blast site.
4.1. Define public and commercial access, and traffic volumes.
Page 2
Page 39 of 73

4.2. Determine the relative location and condition of nearby structures.
4.3. Determine vibration and air overpressure limits per NFPA 495.
4.4. Determine public and regulatory notification requirements.
4.5. Know the location and condition of all nearby utilities that are above and below the ground
or water surface.
4.6. Study the local area blasting history with respect to incidents, damage claims, or litigation.
4.7. Determine specific environmental impacts that might require special blasting control measures.
4.8. Define hazardous material notification requirements for employees. SDS books will be placed
in each piece of equipment and all trucks. SDS used on daily basis will be discussed in the PJB.
4.9. Electric detonators must not be used!
5. BLAST EMERGENCY PLAN
The elements of specific blast emergency plans shall vary based on the unique conditions that exist at
each job site. Emergency plans shall:
5.1. Include a posted list of all emergency response telephone numbers including; ambulance,
hospital, OSHA or MSHA district office, police, BATF, and home phone numbers of
employees.
5.2. Be clearly communicated to and understood by all site workers and supervisors.
5.3. Define notification procedures for contacting supervisors, family, and regulatory agencies
based on the nature of an incident or accident.
5.4. For each work site, the location of first aid kits and the identity of trained first aid providers
shall be known by all workers at the site.
6. EXPLOSIVE TRANSPORTATION
The Blaster -In -Charge will ensure that the Explosives truck will be met by PRS employees at the
intersection of Old US Hwy 1 & Corinth Road. Explosives truck shall be escorted to the blast site by
PRS employee.
All vehicles hauling explosives will be properly loaded and display adequate explosives warning signs
as .specified by either OSHA, MSHA, DOT —whichever is applicable.

Drilling and Blasting Job Hazard
6.1. All vehicles will have appropriate safety equipment, as required by state and federal
regulations. Working fire extinguishers and spill containment kits.
6.2. Passengers shall not accompany explosives.
6.3. Equipment or other materials must never share the same cargo space with explosives.
6.4. Explosive vehicles, safety equipment, and day boxes shall be regularly inspected, maintained
and cleaned.
6.5. All explosives, and any traces of explosives, must be removed from transportation equipment
before it is serviced.
6.6. Explosives day boxes shall be properly built and marked as required by OSHA regulations.
6.7. When detonators and explosives are transported in a day box, they shall be separated by a
four -inch hardwood, or equivalent, partition.
6.8. Only vehicles that are used for transporting or loading explosives shall be allowed on the
blast site.
6.9. Proper shipping papers shall accompany explosives when they are delivered to and from the
job site.
6.10. Explosive transportation must be undertaken under the supervision of a driver who is familiar
with the hazards involved, and the actions required in the event of fire or other abnormal
occurrence.
6.11. No more than the amount of explosives or blasting agents needed for a shift's requirements
shall be taken to the blast site. After loading is completed, all unused explosives and detonators
shall be taken from the site at the end of each shift. NO EXPLOSIVES SHALL BE STORED
ON SITE.
7. BLAST DESIGN
In many blast applications, it is often impossible to fully satisfy all of the design objectives. Therefore,
some sort of trade-off analysis is needed to balance design sacrifices based on priority. In blast design
work, there are usually two general types of goals: 1) safety goals and 2) operational goals. Whenever
safety goals conflict with operational goals, the safety concerns shall have the highest priority. For
instance, producing minus 36-inch rock might be an operational objective while eliminating flyrock is
a safety goal. Since the safety goals must have the highest priority, the blast plan might specify the use
of conservative amount of stemming to control rock movement, thus sacrificing rock fragmentation in
the collar area. The following guidelines shall be used to evaluate all blast design choices:
Page 4
Page 41 of 73

110 PALMETTO ROCK
DRILLING & BLASTING
Analysis
Drilling and Blasting Safety
General Blast Design Considerations:
Drilling and Blasting Job Hazard
7.1. Blast designs shall never compromise safety, and safety goals shall have the highest design
priority.
7.2. While satisfying all primary design objectives, blast designs shall be as simple as possible.
7.3. The blast designer(s) must have thorough knowledge and understanding of the blast
requirements and constraints for each individual application. If the lead blaster is unfamiliar
with a particular application, design, or product, outside help shall be obtained from a
consultant or explosive -supplier representative who is familiar with the application or product.
7.4. Blast design geometry shall be appropriate for the application. The geology of the blast site
and area control requirements must be considered when selecting hole size, explosive diameter,
stemming height, and all other design dimensions.
Initiation System Guidelines:
7.5. Initiation systems must provide adequate protection against stray current hazards.
7.6. Delay timing schemes shall be as simple as possible, while providing adequate burden relief
and sufficiently advanced in -hole energization to prevent surface cut-off failures.
8. BLAST PLANNING
Good advance planning and preparation work will improve blasting productivity and safety. Blast planners
shall:
8.1. Determine the number, skill and experience requirements of drillers, blasters, and helpers
required to perform the work.
8.2. Prepare a blasting work schedule that allows for unforeseen problems or delays.
8.3. Develop plans for dealing with special environmental conditions might occur during this
work. Examples are lightning, floods, cold or hot weather, etc. Palmetto Rock will work under
Morgan Corp plan.
8.4. Define and obtain any special equipment that may be needed for the blasting work.
8.5. Plan to have back-up units to replace critical instruments like non-
electric initiating devices.

9.5. Drillers shall monitor bit wear and penetration rates, and they shall vary feed pressure,
hammer rates, and other operating variables to achieve maximum bit life.
9.6. The -Blaster -In -Charge shall establish a system for marking hole collar locations. Drillers
shall collar holes as close as possible to the designed collar location and they shall carefully
align the drill boom to guide the drill stem along the intended hole path.
9.7. The driller's primary goal is to drill properly aligned and clean holes. Driller should vary hole -
flushing rates and determine which drill settings are producing the cleanest and most accurately
placed holes.
9.8. Holes shall never be drilled in any positions where there is any chance they might intersect
another live hole. Unless a specific variance is granted, the minimum collar distance from a
loaded hole must be greater than the planned depth of the newhole.
9.9. For surface blasting, drillers shall note any unusual conditions or adjustments to the original
plan. Drill log information shall be submitted to the Blaster -In -Charge at the end of each

13.2.1. The Blaster -In -Charge shall coordinate blasts, with all concerned parties, on
an approved blasting schedule.
13.2.2. When the area is secure, a primary initiating device shall be connected to the
shot approximately five minutes before the scheduled blasting time.
13.2.3. The Blaster -In -Charge shall then have the five-minute blast warning signal
given to warn all in the area that a blast is impending.
13.2.4. Four minutes later, the one minute blast warning signal shall be given if all
persons, including the shot -initiator, are in a safe location and all guards confirm that the blast
area is still secure.
13.2.5. At blast time, if the blast area is secure, the Blaster -In -Charge shall fire or
instruct the designated shot firer to fire theblast.
13.2.6. After post blast fames have dissipated. The Blaster -In -Charge shallinspect
the shot area. This examination shall look for
Dangerous rock conditions (watch for large openings in the muck pile)
The presence of undetonated explosives and/or initiators
Abnormal blast conditions and any other hazards

Drilling and Blasting Job Hazard
13.2.7. If misfires or other hazards are present, the Blaster -In -Charge shall supervise
the removal of the hazard by the most appropriate means available.
13.2.8. When the area is clear of hazards, the Blaster -In -Charge shall give the all
clear signal allowing work to resume in the area.
14. MISFIRE PROCEDURES
When blasting misfires occur, or are suspected, their existence and extent must be carefully established under
the direction of the Blaster -In -Charge.
14.1. The Blaster -In -Charge shall provide proper safeguards for excluding all non essential
personnel from the blast site. All non -electric tubing shall be carefully traced and a search
made for unexploded charges.
14.2. No other work shall be done except that necessary to remove the hazard of the misfire and
only employees needed to do the work shall remain in the blast site.
14.3. No attempt shall be made to extract explosives from any charged or misfired hole. A new
primer shall be placed in the hole and detonated.
14.4. Expand the blast exclusion zone due to the increased fly rock potential when misfires are re -
blasted.
14.5. No drilling, digging, or picking shall take place until all misfired holes have been detonated or
the Blaster in Charge has approved that work can proceed.
14.6. Drilling a hole next to a misfired hole in an attempt to fire the hole by propagation is not
allowed.
14.7. If the misfire causes the charge to burn, or a burning charge is suspected, the blast site should
not be approached for at least 1 hour.
15. BLAST REPORTS
Individual blast reports shall be prepared for each blast. Blast reports shall include the following:
15.1. Blast date, time, and location.
15.2. Blast geometry, including, but not limited to, hole size(s), hole depths, drill pattern, number
of holes, bench height, and sub -drilling.

15.3. Blast hole loading summaries, including typical hole loads, explosive types, primers, detonator
delays, stemming type and quantity, and total explosive consumption byproduct.
15.4. Shot volume and powder factor calculations.
15.5. Initiation timing scheme, including in -hole delays, surface delays, and planned hole firing
times.
15.6. Blast effect monitoring data (if applicable), such as ground vibration levels, air overpressure,
and peak water pressures [IF APPLICABLE].
15.7. Notes about blast results, unusual conditions, occurrences, or special precautions.
15.8. Name and signature of the Blaster -In -Charge.
