cumulative adverse effects on the aquatic environment. NEPA requires consideration of •'
all environmental impacts, not only those to aquatic resources, so there may well be
situations where aquatic impacts are minimal even though environmental impacts more

Atlantic will restore the wetlands to preconstruction elevations and will re -vegetate
emergent, scrub -shrub and forested wetlands within the 75 -foot construction corridor. In
addition, Atlantic has placed the following additional protective language into the landowner
easement agreements on parcels which contain waters of the US that are being negotiated for the
pipeline project. This language has been reviewed and approved by Wilmington District.
"IfLocal, State or Federally -regulated waters or wetlands (collectively and individually
"Regulated Waters or Wetlands) within the Permanent Easement or Temporary Easement are
disturbed by Grantee, Grantor acknowledges that Grantee may be required by law to restore
and/or re -vegetate any such disturbed Regulated Waters or Wetlands. Additionally, Grantor
agrees to: (a) cooperate with Grantee to ensure any such restored or re -vegetated Regulated
Waters or Wetlands are maintained as required by applicable laws,; (b) notify Grantee
in advance of any proposed plans to disturb any Regulated Waters or Wetlands within the
Permanent Easement or Temporary Easement; and (c) notify Grantee of Grantor's efforts to
obtain any required permits, permit modifications andlor approvals, prior to conducting any
proposed disturbance of Regulated Waters or Wetlands within the Permanent Easement or
Temporary Easement. Grantor agrees that any permitting and/or disturbance of Regulated
Waters or Wetlands by Grantor within the Permanent Easement or Temporary Easement, Is
including any required mitigation and/or penalties, will be at Grantor's own risk and cost. "
FERC NEPA ALTERNATIVES ANALYSIS INFORMATION
For purposes of the USACE evaluation of single and complete projects, the "alternatives
analysis" is to ensure that the crossing of each wetland, stream and/or other waterbody is made in
a manner that avoids and minimizes impacts on the aquatic environment to the maximum extent
practicable, after considering the approach to the crossing in the uplands immediately adjacent to
the water of the United States. For example, to the extent practicable, crossings will be
perpendicular to the aquatic feature to minimize the length of the pipeline in the particular
aquatic system.
As background, information on the FERC alternatives analysis follows, including
discussion of the various alternatives FERC is considering. Within the sections below, the
numbering of many of the referenced tables and figures has not been changed from their
numbering in the FERC documentation, to maintain consistency across documents
(e.g., Table 10.8.1-1, Figure 10.8.1-1, etc.).Atlantic has identified and evaluated a number of
alternatives to the proposed ACP. These include a no -action alternative; alternative energy
sources, including traditional and renewable sources; energy conservatior
alternative; and conceptual collocation route alternatives.

D. IMPACT JUSTIFICATION AND MITIGATION
1. a.1 Avoidance and Minimization
For purposes of the USACE evaluation of single and complete projects, the "alternatives
analysis" is to ensure that the crossing of each wetland, stream and other waterbody is made in a
manner that avoids and minimizes impacts on the aquatic environment to the maximum extent
practicable, after considering the approach to the crossing in the uplands immediately adjacent to
the water of the United States. For example, to the extent practicable, crossings will be
perpendicular to the aquatic feature to minimize the length of the pipeline in the particular
aquatic system.
The FERC NEPA process includes the evaluation of alternative route alignments that
reduce the overall impacts on the human environment of the proposed pipeline including
avoiding and minimizing impacts to wetlands, streams, and other waterbodies. In addition all
crossings within the Wilmington District have been designed to meet NWP 12 criteria also
resulting in further avoidance and minimization of impacts. As background, information on the
FERC alternatives analysis follows, including discussion of the various alternatives FERC is
considering. The USACE is a cooperating agency on the FERC NEPA EIS and is working with
FERC to ensure that USACE comments regarding the overall pipeline alternatives analysis are
fully considered in that process. The fact that the ACP will be subject to an EIS does not
preclude the use of NWP 12 for the affected waterbody crossings. As provided for in the
USACE 2012 NWP Federal Register (FR) final NWPs:
"One commenter requested clarification that individual permits are not automatically
required for NWP 12 activities when a Corps districtparticipates as a cooperating
agency for an environmental impact statement. [Response] "Even though an
environmental impact statement may be prepared for a particular utility line, the
National Environmental Policy Act process does not prohibit the Corps from using
NWP 12 to authorize the construction, maintenance, repair, and removal of utility lines
and associated facilities in waters of the United States, as long as the activity complies
with all applicable terms and conditions and results in minimal individual and

Atlantic's analysis of route alternatives and variations used a geographic informat
system (GIS) to characterize crossings of environmental features and other constraints alc
routes. A digital centerline for each route alternative and the corresponding segment of tl
baseline was compared with a variety of datasets and map resources in the GIS. Features
constraints considered in the analysis included: length, public lands crossed, roads crosses
conservation easements crossed, forested lands crossed (based on the National Land Cover
Database), wetlands crossed (based on the NWI), waterbodies crossed (based on the National
Hydrography Dataset), and known cultural resources sites crossed, such as Civil War
battlefields.
E
Once a baseline route was determined using desktop data, a field oriented routing team
consisting of a lead construction router, civil survey staff, and an ecological specialist adjusted
the route based on site-specific conditions while weighing competing constraints associated with
environmental, tribal, and historical resource protection, constructability, available technology,
and logistical constraints. Where practicable, adjustments to the route were made to avoid and/or
minimize impacts on wetlands and waterbodies.
Johnston County, North Carolina Major Route Alternative
Atlantic identified and evaluated an alternative route for the AP -2 mainline at the request
of the Johnston County, North Carolina Economic Development Authority in an effort to move
the pipeline closer to existing industrial properties along the 1-95 corridor and U.S. Highway 701
south of the town of Four Oaks. The Johnston County Economic Development Authority would
like to introduce natural gas into the industrial park. The baseline route for the AP -2 mainline in
this area crosses Johnston County east of the towns of Smithfield and Four Oaks.
Beginning at MP 92.9 near Smithfield, the alternative route follows an existing electric
transmission line southwest of the baseline for approximately 7 miles to a point just south of
Four Oaks. The route then heads to the south-southwest for approximately 14 miles, where it
rejoins the baseline west of Jumping Run Swamp at MP 114.5. The baseline and Johnston
County route alternative are depicted on Figure 10.8.1-14, and comparative information on each
route is provided in Table 10.8.1-12.

Nationwide Permit No. 12, Pre -Construction Notification — Supplemental Information
• U.S. Army Corps of Engineers — Wilmington District
environmental impacts are expected should an inadvertent release occur. Similarly, while native
soils may mix with the drilling fluid as a result of the drilling process, drilling fluid is still not
considered fill material and no adverse environmental impacts from these materials are expected
should an inadvertent return occur.
Due to the possibility of drilling fluid loss during HDD operations, Atlantic has prey --4
and will implement a HDD Plan. The plan describes measures to prevent, detect, and resp(
inadvertent returns, including but not limited to, monitoring during drilling operations, the 1
of equipment and materials that must be readily available to contain and clean up drilling in l i/�I✓1 ll�
containment and mitigation measures, notification requirements, and guidelines for abandol
the directional drill, if necessary.
The use of HDD was considered for wetland and waterbody crossings, but was
determined to not be feasible in all crossing locations based on logistical, economic, tempor
and engineering constraints, additional environmental impacts, and potential environmental
The HDD method requires that a prefabricated segment of pipe at least the length of the bon
hole be staged in line with the drill path at the exit hole, opposite the placement of the drilliny,
rig. This "pullback" generally requires a false right-of-way that can deviate from the right-of-
way approaching the crossing, unless the drill alignment is directly in-line with the construction
right-of-way for the length of the prefabricated pipe segment. In many cases the drill path is not
in-line with the construction right-of-way and additional workspace that extends well outside of
the standard construction right-of-way must be cleared and graded to accommodate the
• prefabrication of the pipe segment described above.
The path of the drill is constrained by the flexibility of the pipe; the depth beneath the
wetland and/or waterbody needed to achieve a successful installation; and the elevation of the
entry and exit points. The entry and exit points should be similar in elevation to prevent a
significant pressure differential that can contribute to failure of the HDD operation and by
maintaining consistent pressure this helps maintain predictable flow of drilling mud and thus
greater likelihood of a successful HDD.
As a rule of thumb used in evaluating the feasibility of the HDD method, the 36 -inch
diameter pipe requires a minimum drill path of 1,800 feet to achieve an acceptable radius of
curvature that will prevent a catastrophic "crinkling" of the pipe as it conforms to the path of the
drill hole. All proposed HDD crossings have been designed based on specific site constraints at
the crossing and geologic conditions, therefore site-specific designs may vary from the planning
guidelines.
Atlantic explored use of the HDD method at the Rocky Swamp crossing, but based on
geotechnical results, due to heavily weathered bedrock and overlying unconsolidated materials,
the likelihood of experiencing an inadvertent release was high. Therefore, the HDD method is
not proposed for the Rocky Swamp crossing.
A large drill can be more expensive than traditional crossing methods and can take as
long as several months to install. Traditional crossing methods of major waterbodies can
typically be completed in less than 30 days for major waterbody crossings, whereas typical
• minor or intermediate waterbody crossings can be completed within a day or a few days. Due to
Atlantic Coast Pipeline 80

Nationwide Permit No. 12, Pre -Construction Notification — Supplemental Information
U.S. Arany Corps of Engineers — Wilmington District
the extended time of exposure of additional workspace associated with HDD coupled with the
potential for an inadvertent return, traditional crossing methods can often reduce the
environmental impact when compared with HDD. Based on these constraints and design
considerations the HDD method is feasible and practicable where large, deep waterbodies are
encountered and sufficient space to place the pullback and work area for drilling equipment is
available.
The proposed HDD crossing locations on ACP constitute those where it is feasible and
the potential for a successful drill is acceptable.
Once construction is complete, the pipeline will be buried below the ground surface and,
therefore, will not impact water retention or floodplain storage within riparian corridors.
Atlantic is routing the proposed pipelines to avoid sharp angle crossings or crossing streams
where high stream energy could result in bank erosion. Atlantic will implement measures
outlined in the Procedures to minimize impacts on the waterbodies crossed, including the
installation of trench plugs to prevent water from flowing along the trenchline during and after
construction. These measures will minimize potential impacts on surface and below ground
hydrology. All waterbody crossings will be in accordance with the requirements identified in the
federal or state waterbody crossing permits obtained for the ACP.
During operations, the proposed pipelines will transport natural gas, which consist
primarily of methane. Methane is buoyant at atmospheric temperatures and pressure, and
disperses rapidly in air. The proposed pipelines will not carry liquids. Therefore, in the unlikely
event of a leak, impacts on surface waters or groundwater from methane are not anticipated.
Moreover, Atlantic will utilize a rigorous Integrity Management Plan to prevent leaks on the
system.
The impacts associate with construction are planned to occur in an expedient and
efficient manner such that impacts on the waterbody its banks are temporary in nature. In
addition, while there are numerous of waterbody crossings across the project in North Carolina,
the crossings are distributed across many watersheds. Tables 3 and 4 in section C, Proposed
Impacts Inventory, summarize the impacts on waterbodies by sub -basin (HUC 8). Based on the
short duration and distant nature of the waterbody crossings, Atlantic anticipates that cumulative
impacts will result in no more than minimal adverse impacts on the basin and sub -basins crossed.
See Appendix K — Tables K-1 to Table K-3 for a list of General, Regional and Specific
NWT 12 permit conditions and how Atlantic will comply with the conditions.
2. Compensatory Mitigation for Impacts on Waters of the U.S. or Waters of the State
In order to authorize any activity under the NWP Program the USACE must determine
that the authorized activity in waters of the U.S. meets the terms and conditions of the relevant
NWP, in this case NWP 12, which allows no more than 0.5 acre loss at each single and complete
project (crossing). Furthermore, provided the activity meets the terms and conditions of NWP 12
USACE must determine that the activity will result in no more than minimal individual or
cumulative impacts on the aquatic environment after considering proposed compensatory
Atlantic Coast Pipeline 81

• mitigation. Such impacts would include the conversion impacts from one type of wetland to
another. As stated in the Preamble to 33 CFR 330/NWP Rule issued on November 22, 1991
(56 FR 59118-59119) mitigation can be used to reduce impacts on the aquatic environment to the
minimal level:
"In response to the comments concerning whether the District Engineer (DE) should
allow an activity to proceed under a relevant NWP when the mitigation reduces the adverse
environmental effects to the minimal level (the "buy down" or "write down " concept), we
believe it is indeed appropriate for the DE to consider mitigation in determining whether the
proposed activity will result in no more than a minimal level of adverse environmental effects.'
and "In summary, the net impact concept regarding the determination of minimal is consistent
with NEPA, the Army/EPA Mitigation Memorandum of Agreement and the Section 404(b)(1)
Guidelines as they pertain to general permits."
Atlantic will provide compensatory mitigation for the conversion within the 30 foot
permanently maintained right of way (15 feet either side of the pipeline centerline) reseeding
with native wetland seed mix and mitigating at a 1:1 ratio for permanent conversion of palustrine
forested wetlands to scrub -shrub or to emergent wetlands, and within the temporary disturbed
construction right of way reseeding with native wetland seed mix to stabilize the area, along the
ACP right-of-way.
Permanent loss of wetlands is not proposed for anticipated to occur as a result of the ACP;:'
mainline pipeline construction or associated facilities in North Carolina. However, loss of
40 waters of the U.S. will occur as a result of access road improvements. Existing access roads will
be utilized as much as possible where feasible. Where access road improvements are necessary
for use, impacts will be minimized to the maximum extent practicable, and, in conjunction with
other impacts will not result in more than 0.5 acre loss of waters of the U.S. at any single and
complete project.
Permanent losses of wetlands, streams, and other waters as a result of access roads are
proposed to be mitigated at a 2:1 ratio for riparian wetland type and 1.5:1 ratio for non -riparian
wetland type through the purchase of commercially available mitigation credits from an agency -
approved mitigation bank as a first option, and from the Department of Mitigation Services
(DMS), which offers In -Lieu Fee mitigation programs, as a second option. Atlantic requested
authorization from DMS to reserve 100% of the credit need for the permanent loss of wetlands
and streams while submitting requests for letters of credit availability from mitigation banks
servicing the HUC 8 watershed or approved service area where the loss will occur. In-kind
mitigation bank credits will be purchased from mitigation banks servicing the areas (HUC 8
watershed, or approved service area) where the conversion or loss occurs. Atlantic received
notification that DMS is willing to accept payment for compensatory mitigation for the total
permanent loss of wetlands and streams associated with the construction and maintenance of
access roads. Should mitigation banks indicate that credits are available, Atlantic will purchase
all available credits before making a payment to DMS for the balance.
In addition, in the event that a conversion or loss occurs in a service area where
mitigation bank credits are not available, Atlantic will seek authorization to participate in an
• agency approved In -Lieu Fee program and/or, Atlantic will seek authorization to purchase
Atlantic Coast Pipeline 82

Nationwide Permit No. 12, Pre -Construction Notification — Supplemental Information
U.S. Army Corps of Engineers — Wilmington District
credits from outside the service area of the next nearest mitigation bank and/or conduct permittee
responsible mitigation (PRM) under an umbrella approach. These options will be based on
practicality to replace the ecological function of the temporal loss and amount of compensation
required. Atlantic will coordinate with Wilmington District in such cases in order to obtain
approval of either option in instances where credits are not available from an agency -approved
mitigation bank.
Atlantic has completed research to identify wetland mitigation banks with available
credits, and will continue to contact wetland mitigation banks to identify available wetland
mitigation banks as the primary source of compensatory mitigation for the ACP. As a secondary
source of compensatory mitigation, Atlantic will pursue participation in the North Carolina In -
Lieu Fee program and/or conduct PRM if adequate wetland mitigation bank credits are not
available from an agency -approved bank.
For purposes of NCDEQ for the 401 Water Quality Certification Atlantic has received a
response letter from DMS outlining required mitigation for loss of wetlands, loss of linear feet of
stream bed, and for riparian buffer impacts. Atlantic has attached this letter as evidence of intent
to satisfy NCDEQ required mitigation. The letter is included in Appendix P.
With respect to PRM, Atlantic's team is currently in the process of identifying RUC's
where an umbrella PRM approach may be applicable. Based on this research, Atlantic's team has
`1abegun coordinating with landowners to identify suitable sites and is in the process of negotiating
with landowners in order to conduct site research and assessments. Once suitable sites are
selected and upon coordination with Wilmington District, Atlantic's team will be available to
coordinate and schedule site visits to review the selected sites prior to final approval of the
umbrella PRM approach.
Atlantic intends to complete field survey on remaining inaccessible parcels, analyze and
confirm impacts, and finally purchase adequate mitigation credits and/or secure sites to support
the umbrella PRM approach. Atlantic will pursue this sequence of steps to provide for
compensatory mitigation prior to final issuance of the JPA.
3. Complete if Using a Mitigation bank
See Section D2 above for mitigation options. Additional details will be provided in the
final application regarding Atlantic's plans for mitigation bank use and availability in North
Carolina. At the time of this draft application, Atlantic continues to plan for mitigation and has
provided a conceptual plan in Section D2 above.
4. Complete if Making a Payment to In -lieu Fee Program
See Section D2 above for mitigation options. Additional details will be provided in the
final application if Atlantic plans to utilize payment to the North Carolina in -lieu fee program as
a compensatory mitigation option.

Cumulative Impacts Assessment for the
• Atlantic Coast Pipeline and Supply Header Project
The distance into the past and future that other projects could cumulatively impact
the same areas as the Projects is based on whether the impacts are short term, long
term, or permanent. The majority of the impacts related to the Projects will occur
during the construction phase. Atlantic and DTI are proposing to begin
construction in the Fall of 2016, assuming all necessary permits and regulatory
approvals are obtained, and placing the proposed ACP and SHP facilities into
service by the end of 2018.
Where a potential for cumulative impacts was indicated, those impacts have been
quantified to the extent practicable. In most cases, however, the potential impacts
could only be described qualitatively (e.g., impacts from projects that are in
planning stages or are contingent on economic conditions, availability of
financing, or the issuance of permits).
The criteria listed below define the Projects' region of influence, which is used in this
cumulative impacts assessment to describe the general area for which the Projects could
contribute to cumulative impacts. The region of influence varies depending on the resource
being discussed.
Potential impacts of the Projects on geology and soils, land uses, residential areas,
visual resources, cultural resources, and traffic will be highly localized; therefore,
other projects within 0.5 mile of the ACP and SHP work areas (e.g., commercial
40 developments or transportation projects) were evaluated for cumulative impa
on these resources.
Waterbody and wetland crossings, as well as potential impacts on groundwat �t
vegetation, and wildlife by the ACP and SHP will be localized. Therefore, d
analysis included cumulative impacts on these resources from other projects
within the same watersheds crossed by the Projects.
Ongoing operation of the ACP and SHP compressor stations will result in
continuing impacts on air quality in various Air Quality Control Regions
(AQCRs). Therefore, other projects with the potential to result in continuing
impacts on air quality (e.g., natural gas compressor stations or industrial facil......
within the AQCRs that will also be impacted by an ACP or SHP compressor
station were considered.
Continuing noise impacts from the ACP or SHP compressor stations will be
localized to within 0.5 mile of each compressor station. Therefore, other projects
that will result in continuing impacts on noise affecting the same noise -sensitive
areas (NSAs) as the ACP and SHP compressor stations were evaluated.
The anticipated cumulative impacts of the Projects and other actions are discussed below.
2.0 PROJECTS AND ACTIVITIES CONSIDERED
Atlantic and DTI identified past, present, or reasonably foreseeable projects from review
• of topographic maps, intemet research, and by contacting County and City officials regarding
10-5

Cumulative Impacts Assessment for the
Atlantic Coast Pipeline and Supply Header Project
recent or planned developments and significant commercial/industrial developments within the
Counties and Cities crossed or affected by the Projects. Table A-1 in Attachment A lists past,
present, and reasonably foreseeable future projects that may cumulatively or additively impact
resources that could be affected by construction and operation of the ACP and/or SHP. 5 As
noted in the following subsections, some projects were eliminated from further consideration if it
was determined that they will not meet the criteria listed above or if insufficient information is
available to allow for a meaningful analysis.
Descriptions of potential cumulative impacts by resource category are presented in
Section 3.0. In cases where quantitative information is not available for the projects considered
in this analysis (e.g., projects in the planning stages or those contingent on economic conditions,
availability of financing, or the issuance of permits), the potential impacts of those projects have
been considered qualitatively.
Other Known Federal Energy Regulatory Commission -Jurisdictional Projects
In addition to the projects listed in Table A-1, there are FERC jurisdictional natural gas
projects recently completed, currently proposed, recently approved, or under consideration in the
States/Commonwealths crossed by the ACP and SHP, but not the same Counties or Cities.
These include the Atlantic Sunrise Project in North Carolina, Pennsylvania, and Virginia;
Constitution Pipeline and Wright Interconnect Projects in Pennsylvania; East Side Expansion
Project in Pennsylvania; Marcellus to Manhattan Project in Pennsylvania; Niagara Expansion
Project in Pennsylvania; Northeast Expansion Project in Pennsylvania; Northern Access 2015 —
West Side Expansion Project in Pennsylvania; West to East Overbeck to Leidy Project in
Pennsylvania; Giles County Project in Virginia and West Virginia; Kingsport Expansion Project
in Virginia; Smithfield III Expansion Project in West Virginia; Uniontown to Gas City
Expansion (U2GC) Project in Pennsylvania; and West Side Expansion and Modernization
Project in Pennsylvania and West Virginia. None of.these projects will occur within the same
region of influence as the ACP and SHP; therefore, they are not discussed further.
There are several FERC jurisdictional projects currently proposed, under consideration,
being constructed, or recently completed that are located in whole or in part in the same Counties
or Cities as some of the ACP and SHP facilities. These include the Mountain Valley Pipeline
Project in Doddridge, Harrison, Lewis, Tyler, and Wetzel Counties, West Virginia (in pre -filing);
Rover Pipeline Project in Tyler and Doddridge Counties, West Virginia (in pre -filing); Natrium
to Market Project in Greene and Westmoreland Counties, Pennsylvania (completed in 2014);
Texas Eastern Appalachia Market 2014 Project in Westmoreland County, Pennsylvania
(construction ongoing), and Virginia Southside Expansion Project in Brunswick County,
Virginia (construction ongoing). These projects are included in the cumulative impacts
assessment (see Table A-1 in Attachment A).
' Because the majority of potential project impacts will occur during the construction phase, the past projects included in Table A -I primarily
are recently completed projects (2014 or later). Projects completed prior to 2014 are considered part of the environmental baseline and are
removed from fiuther consideration unless operational impacts would affect the same resources as the ACP and SHP.
