Spill Prevention, Control, and Countermeasure Plan
1.0 INTRODUCTION
Atlantic Coast Pipeline, LLC (Atlantic) — a company formed by four major energy
companies — Dominion Resources, Inc.; Duke Energy Corporation; Piedmont Natural Gas Co.,
Inc.; and AGL Resources, Inc. — proposes to construct and operate approximately 600 miles of
natural gas transmission pipelines and associated aboveground facilities in West Virginia,
Virginia, and North Carolina. This Project, referred to as the Atlantic Coast Pipeline (ACP), will
deliver up to 1.5 million dekatherms per day of natural gas from supply areas in the Appalachian
region to demand areas in Virginia and North Carolina. Atlantic has contracted with Dominion
Transmission, Inc. (DTI), a subsidiary of Dominion Resources, Inc., to construct and operate the
ACP on behalf of Atlantic.
In conjunction with the ACP, DTI proposes to construct and operate approximately
37.5 miles of pipeline loop and modify existing compression facilities in Pennsylvania and West
Virginia. This Project, referred to as the Supply Header Project (SHP), will enable DTI to
provide firm transportation service to various customers, including Atlantic.
2.0 PURPOSE
The purpose of this Spill Prevention, Control, and Countermeasure Plan (SPCC Plan) is
to identify preventive measures, such as training, equipment inspection, and refueling
procedures, to reduce the likelihood of spills; and mitigation measures, such as containment and
cleanup, to minimize potential impacts should a spill occur. Atlantic's and DTI's construction
Contractors, I whose activities could result in a spill of fuel or other hazardous materials, will be
required to adopt the following protocols for spill prevention, cleanup, and reporting during
construction of the ACP and SHP.
3.0 TRAINING
Prior to the start of construction, Atlantic and DTI will conduct environmental and safety
training for Company and Contractor personnel. The training program will focus on the Federal
Energy Regulatory Commission's Upland Erosion Control, Revegetation, and Maintenance Plan
and Wetland and Waterbody Construction and Mitigation Procedures; other construction,
restoration, and mitigation plans, including this SPCC Plan; and applicable permit conditions. In
addition, Atlantic and DTI will provide large -group training sessions before each work crew
commences construction with periodic follow-up training for groups of newly assigned
personnel.
Experienced, well-trained personnel are essential for the successful implementation of the
SPCC Plan. Contractors will provide spill prevention and response training to their work crews.
The training program will be designed to improve awareness of safety requirements, pollution
control laws, and proper operation and maintenance of equipment. Contractors will train all
employees who handle fuels and other regulated substances to prevent spills and to quickly and
Contractor or Contractors refer to the company or companies retained by Atlantic/DTI or another contractor to construct the proposed
facilities.

Spill Prevention, Control, and Countermeasure Plan
effectively contain and cleanup spills that may occur in accordance with applicable regulations
and the provisions of this plan.
4.0 ROLES AND RESPONSIBILITIES
A. Spill Coordinator — Each Contractor will appoint a Spill Coordinator who will be
responsible for coordinating Contractor Work Crews for spill cleanup, conducting
site investigations, and completing spill reports. The Spill Coordinator will report
spills to an Environmental Inspector (EI) 2, who will initiate the spill reporting
process (see Section 7.0). The Spill Coordinator will be responsible for
completing a Spill Report Form (Attachment A) within 24 hours of the occurrence
of a spill, regardless of the size of the spill.
B. Contractor Work Crews — Contractor Work Crews will comply with this SPCC
Plan and will notify the crew foreman or Spill Coordinator immediately of a spill
of fuel or other hazardous material, regardless of the volume of the spill.
C. Environmental Inspectors — The EIs will monitor the Contractors' compliance
with the provisions of the SPCC Plan to ensure that spill resources are allocated
and cleanup is accomplished in accordance with this plan and applicable
regulatory requirements. The EIs will work in conjunction with Atlantic's and
DTI's environmental team to promptly report spills to appropriate Federal,
State/Commonwealth, and local agencies, as required, and to coordinate with
these agencies regarding contacting additional parties or agencies as may be
required.
5.0 PREVENTIVE MEASURES
Contractors will minimize the potential for a spill during construction activities by
implementing appropriate measures to prevent and contain spills. Equipment and materials will
be located onsite to meet the provisions of this plan. The Contractors will comply with
applicable environmental and safety laws and regulations and will ensure that a copy of this plan
is available onsite to all Construction Work Crew members. All cleanup and other construction -
related spill activities will be completed by the appropriate Contractors.
Spill prevention measures are described below.
A. Petroleum and Hazardous Liquid Storage, Refueling, and Equipment
Maintenance
Staging Areas and Facility Sites:
a. Prior to construction, the Contractors will provide site-specific
descriptions and maps depicting locations of fixed and mobile
2 The role and responsibilities of an EI are defined in the Federal Energy Regulatory Commission's Upland Erosion Control, Revegetation,
and Maintenance Plan.
2

Spill Prevention, Control, and Countermeasure Plan
hazardous material containers and the types of materials located
within containers. The site-specific descriptions and maps will
identify the direction, rate of flow, and total quantity of petroleum
or hazardous liquid which could be discharged from containers or
from major equipment failures.
b. Contractors will visually inspect aboveground storage containers
for leaks and spills on a regular basis and whenever containers are
refilled. Contractors will maintain inspection records for every
container.
Contractors will construct secondary containment structures (e.g.,
temporary liners and seamless impermeable berms) around
aboveground, single wall, storage containers so that liquids will be
contained and collected in specified areas isolated from
waterbodies in the event of a leak or spill. Double wall containers
will not require secondary containment. Storage containers will
not be placed in areas subject to periodic flooding and washout.
d. Secondary containment structures must provide a containment
volume equal to a minimum of 110 percent of the maximum
storage volume of the storage container for single wall containers.
Secondary containment structures must be constructed so that no
outlet is provided and a spill will be contained within the
containment structure. Accumulated rainwater may be removed if
authorized by the EI. Accumulated water with a visible sheen will
be collected for proper storage, transport, and disposal.
£ Contractors will remove all secondary containment structures at
the conclusion of the Projects. Contractors also will be responsible
for returning the storage impoundment area to its original contours
and appearance upon completion of the Projects.
g. Hazardous materials, including chemicals, fuels, and lubricating
oils, will be stored only at designated staging areas and in
appropriate service vehicles. The storage areas will be located at
least 100 feet away from wetlands, waterbodies, and springs; at
least 200 feet away from private water supply wells; at least
300 feet away from karst features; and at least 400 feet away from
municipal water supply wells unless a larger buffer is required by
regulatory agencies.
h. Storage containers will display labels that identify the contents of
the container and whether the contents are hazardous. Contractors
will maintain and provide to Atlantic and DTI, when requested,
copies of all Safety Data Sheets (formally known as Material

Spill Prevention, Control, and Countermeasure Plan
Safety Data Sheets). All containers used for the storage of
hazardous materials, including chemicals, fuels, and lubricating
oils, will be of material and construction compatible with the
material stored and the conditions of storage such as pressure and
temperature. All containers will be in good condition.
Contractors will conduct routine equipment maintenance, such as
oil changes, in staging areas and will dispose of waste oil in an
appropriate manner (e.g., the Contractors will collect the waste oil
in labeled, sealed containers and transport the waste oil to a
recycling facility).
Contractors will correct visible leaks in storage containers as soon
as possible. Leaks outside of secondary containment, regardless of
volume, will be reported to the Spill Coordinator and an EI.
k. Drain valves on temporary storage containers will be locked to
prevent accidental or unauthorized discharges from the containers.
All fuel nozzles will be equipped with functional automatic shut-
off valves.
in. The drivers of tank trucks will be responsible for spill prevention
and the provision of secondary containment during tank truck
unloading. Procedures for loading and unloading tank trucks will
meet the minimum requirements established by applicable law and
associated regulations. Drivers will observe and control the
fueling operations at all times to prevent overfilling. Contractors
will be responsible for training drivers of tank trucks to comply
with these provisions.
n. Prior to departure of a tank truck, all outlets of the vehicle will be
closely examined by the driver for leakage and tightened, adjusted,
or replaced, as necessary, to prevent liquid leakage while in transit.
Contractors will be responsible for training drivers of tank trucks
to comply with these provisions.
2. Right -of -Way:
a. All machinery will arrive on the right-of-way in a clean, washed
condition, maintained free of fluid leaks.
b. Overnight parking of equipment, as well as refueling and servicing
of construction equipment, will be restricted to upland areas at
least 100 feet away from waterbodies, wetlands, and springs; at
least 200 feet from private water -supply wells; at least 300 feet
from karst features; and at least 400 feet from municipal water -
supply wells. Where this is not practicable, and where the EI finds
2

Spill Prevention, Control, and Countermeasure Plan
in advance no reasonable alternative, the equipment will be fueled
by designated personnel with specific training in refueling, spill
containment, and cleanup, under the supervision of an EI. Prior to
refueling, appropriate steps will be taken (including deployment of
secondary containment structures) to prevent spills and provide for
prompt cleanup in the event of a spill.
Fuel trucks transporting fuels to construction areas will only travel
on approved access roads.
d. Contractors will keep a spill kit onsite and on all equipment in case
of machinery leaks or spills. If a spill kit is used, it will be
replaced within 24 hours.
3. Restricted Refueling Areas will be identified in the field with flagging or
signs. A site-specific plan and written approval from an EI will be
required to refuel in restricted areas.
a. Approval must be received from an Atlantic or DTI representative
and, where necessary, appropriate regulatory permits must be
obtained, prior to refueling in Restricted Refueling Areas.
b. In large wetlands where no upland site is available for refueling,
auxiliary fuel tanks may be mounted to equipment to minimize the
need for refueling.
C. Trained Contractor personnel must be available for refueling, and
an EI or another trained Atlantic/DTI representative must be
present.
d. Equipment such as large, stationary pumps will be fitted with
auxiliary tanks as appropriate. The auxiliary tanks will be placed
within secondary containment which provides for a containment
volume equal to a minimum of 110 percent of the volume of the
auxiliary tanks.
e. Refueling within Restricted Refueling Areas will take place in
areas designated by an EI. Fuel trucks with a capacity in excess of
300 gallons will not be allowed within a Restricted Refueling Area
unless adequate secondary containment is provided.
f. Refueling of dewatering pumps, generators, and other small,
portable equipment will be performed using approved containers
with a maximum volume of 5 gallons.
5

Spill Prevention, Control, and Countermeasure Plan
B. Spill Response Equipment
Staging Areas and Facility Sites:
a. Contractors will stock a sufficient supply of sorbent and barrier
materials at construction staging areas to allow the rapid
containment and recovery of a spill. Sorbent and barrier materials
will also be used to contain runoff from spill areas.
b. Shovels and 55 gallon drums will be kept at each individual
staging area. If small quantities of soil become contaminated
within the staging area, they will be collected and placed in the
drums. The drums will be labelled to indicate the contents of the
drum, including the spilled/recovered material.
Large quantities of contaminated soil will be collected using heavy
equipment and will be stored in drums or other suitable containers
prior to disposal. The drums will be labelled to indicate the
contents of the drum, including the spilled/recovered material.
d. The Contractors will dispose of all contaminated soil in accordance
with applicable State/Commonwealth and Federal regulations.
2. Right -of -Way
a. Each construction crew will have adequate absorbent materials and
containment booms on hand to enable the rapid and complete
cleanup of spills, as well as sufficient tools and materials to stop
leaks.
b. Contractors must maintain spill kits containing a sufficient quantity
of absorbent and barrier materials to adequately contain and
recover foreseeable spills. These kits may include, but are not
limited to: absorbent pads, straw bales, absorbent clay, sawdust,
floor drying agents, spill containment barriers, plastic sheeting,
skimmer pumps, and 55 gallon drums. The equipment will be
located near fuel storage areas and other locations, as necessary, to
be readily available in the event of a spill.
All fuel equipment, and where practicable, service trucks, will
carry adequate spill response materials. Spill response materials
present on trucks will consist of absorbent pads, absorbent
material, plastic bags, and a shovel.
d. The Spill Coordinator will inform the EIs and all Contractor
personnel of the location of spill control equipment and materials,
and have them readily accessible while construction activities are
occurring.
2

Spill Prevention, Control, and Countermeasure Plan
If a spill kit is used, it will be replaced within 24 hours.
C. Concrete Coating
Concrete coating activities and washout activities will not be performed
within 100 feet of wetlands, waterbodies, or springs, or with 300 feet of
karst features unless the location is an existing industrial site designated
for such use.
6.0 SPILL RESPONSE
A. The first priorities after discovering a spill are to protect the safety of personnel
and the public and to minimize damage to the environment. Actions to be taken
immediately following a spill will include the following:
1. The safety of the situation (including the surrounding public) will be
assessed.
2. Sources of ignition will be removed from the area by trained personnel if
safe to do so.
3. The source of the spill will be shut off by trained personnel if safe to do
SO.
4. Efforts to contain the spill immediately will be initiated by trained
personnel if safe to do so.
5. Cleanup activities will be initiated as soon as possible after the spill is
contained using properly trained and protected personnel with adequate
spill cleanup materials and equipment (see Section 8.0).
6. If necessary, an Emergency Response Contractor will be secured for large
spills to further contain and clean up the spill.
7.0 SPILL REPORTING
A. All spills will be reported immediately to Atlantic or DTI. Reports will include
the following information (found on the Spill Report Form):
Date, time, and location of the spill.
2. Type of material spilled.
3. Amount of material spilled.
4. Extent of spill area.
5. Whether the material has reached or has the potential to reach a wetland,
waterbody, or karst feature.
6. Status of spill containment and cleanup.
7

Spill Prevention, Control, and Countermeasure Plan
7. Circumstances leading up to the spill.
B. Atlantic's and DTI's environmental team will report the spill to the applicable
regulatory agencies if the spill meets or exceeds a reportable threshold. Table l
lists the Federal and State/Commonwealth agencies that would be contacted, as
appropriate, if a spill meets or exceeds a reportable threshold.
C. Federal standards for reportable quantities (RQs) of hazardous materials are listed
at 40 CFR 302.4, which is incorporated into this SPCC Plan by reference.
Additional requirements by State/Commonwealth are as follows:
Pennsylvania:

D. Contractors are responsible for assisting Atlantic and DTI with preparing follow-
up written incident reports to regulatory agencies upon request.
8.0 SPILL CONTAINMENT AND CLEANUP
A. Land Spill
1. Berms will be constructed with available equipment to physically contain
the spill and sorbent materials will be applied to the spill area. Traffic on
contaminated soils will be prevented to the extent practicable. Some
traffic on contaminated soils may be necessary to avoid impacts on
adjacent or sensitive resources (e.g., wetlands).
2. Contaminated soils and vegetation will be removed and disposed of at a
properly licensed waste disposal facility.
3. Waste materials from the spill will be disposed of according to applicable
regulatory requirements.
4. The following information will be provided to an EI and Atlantic and DTI
as available following containment and cleanup (but no later than 24 hours
after transport and disposal of the contaminated waste material):
10

Spill Prevention, Control, and Countermeasure Plan
a. The amount of the spilled material that was recovered during
cleanup.
b. Proposed reclamation of remaining contaminated areas.
C. Storage method for the contaminated waste material before
transport and disposal.
d. Transport and disposal documentation for the contaminated waste
material.
5. If necessary, an Emergency Response Contractor will be secured for large
spills to further contain and clean up the spill.
B. Wetland or Waterbody Spill: The following measures will be implemented
immediately to control a spill into a wetland or waterbody:
For spills in standing water, floating booms, skimmer pumps, and holding
tanks will be readily available and used, as appropriate, by the Contractors
to recover and contain released materials on the surface of the water.
2. Berms and/or trenches will be constructed in upland areas to contain a
spill before it enters a wetland or waterbody. Deployment of booms,
skimmers, and sorbent materials will be utilized if the spill reaches a
waterbody. The spilled product will be retrieved and the contaminated
area cleaned -up in accordance with recommendations from the Spill
Coordinator and applicable regulations and guidelines.
3. If necessary, an Emergency Response Contractor will be secured for large
spills in wetlands or waterbodies to further contain and clean up the spill.
Approvals or permits from regulatory agencies may be required to place
equipment into a wetland or waterbody. Therefore, Contractors must receive
written permission from Atlantic or DTI before placing equipment into a wetland
or waterbody for the purpose of spill cleanup.
C. Karst: In addition to the measures described above, the following procedures
will be implemented in areas of karst terrain:
Buffers of 300 feet around karst features (e.g., sinkholes, caves, sinking or
losing streams, ponors, pinnacled bedrock, and large springs) within or
adjacent to the construction right-of-way will be marked with signs and/or
highly visible flagging until construction related ground disturbing
activities are completed.
2. Equipment refueling will not be permitted within flagged or marked buffer
areas for karst features or areas draining into karst features, except by
hand -carried cans (5 gallon maximum capacity), when necessary.
11

Spill Prevention, Control, and Countermeasure Plan
3. Equipment servicing and maintenance areas will be sited outside of
flagged or marked buffer areas for karst features or areas draining into
karst features.
4. Erosion and sediment controls will be implemented, as appropriate, to
prevent runoff resulting from construction equipment washing operations
(if applicable) to directly enter a karst feature by locating these operations
outside of karst buffer areas.
5. Construction equipment, vehicles, materials, hazardous materials,
chemicals, fuels, lubricating oils, and petroleum products will not be
parked, stored, or serviced within 300 feet of a karst feature.
6. Equipment will be checked for leaks daily by the Contractors prior to
beginning work in karst areas; and damaged or defective equipment will
be removed or repaired prior to use in karst areas.
7. Atlantic or DTI will notify the National Response Center and either the West
Virginia Department of Environmental Protection or Virginia Department of
Environmental Quality if a reportable spill impacts a karst feature (see Table
1).
