Question Number: 1

Question Subpart: b

Question:

Regarding the Spruce Creek Route Variation that was filed by Atlantic on March 10, 2016:

b. Clarify the number and location of historic properties that would be crossed by

the proposed route and Spruce Creek Route Variation. 1 Update the resource

impact comparison table as necessary.

Response:

Atlantic provided updated information on the number and types of previously recorded

aboveground historic sites located along the Spruce Creek Route Variation and corresponding

segment of the proposed route in its supplemental filing on July 29, 2016 (FERC Accession

Number 20160729-5256). 2 The route variation crosses two previously recorded aboveground

historic sites, and the corresponding segment of the proposed route crosses one.

Both routes cross the South Rockfish Valley Rural Historic District (62-5119), which

encompasses historic farmsteads and small crossroads communities within an agricultural

landscape. The district was determined to be eligible for listing on the National Register of

Historic Places (NRHP) in 2010 under Criterion A for its association with the early agricultural

history of the area and Criterion C for its architecture. The district is currently under review for

listing on the NRHP. Because the district is eligible for listing on the NRHP, it is considered a

“historic property”.

The second previously recorded aboveground historic site crossed by the Spruce Creek Route

Variation is the Elk Hill historic house and farm complex (062-0005), which dates from the

nineteenth century. This site has not been evaluated to determine its eligibility for listing on the

NRHP on an individual basis, but is included within the South Rockfish Valley Rural Historic

District. Therefore, the Elk Hill historic house and farm complex is a component of a larger site

which is considered a “historic property”.

1 Atlantic assumes that the reference to “historic property” in this question refers to properties which are listed on or eligible for listing on the

National Register of Historic Places. 2 Atlantic’s comparison of the Spruce Creek Route Variation to the corresponding segment of the proposed route only considered previously

recorded sites. Field survey results for the proposed route, where available, were not included in the analysis to provide for an apples-to-

apples comparison with the route variation, which was not surveyed for cultural resources. Field survey to date along the corresponding

segment of the proposed route identified one new aboveground historic site, a ca. 1900 residence (062-5161), which is located adjacent to, but outside of, the South Rockfish Valley Rural Historic District. The newly recorded site, which is recommended not eligible for listing on

the NRHP, is discussed in Atlantic’s report titled Architectural Reconnaissance Survey of the Atlantic Coast Pipeline Corridor, Highland

Augusta, Nelson, Buckingham, Cumberland, Prince Edward, Nottoway, Dinwiddie, Brunswick, Greensville, and Southampton Counties, and the Cities of Suffolk and Chesapeake, Virginia. A draft of this report was provided with Atlantic’s Application on September 18, 2015

(FERC Accession Number 20150918-5213), and an updated report addressing comments from FERC staff was provided on April 15, 2016

(FERC Accession Number 20160415-5015). The Virginia Department of Historic Resources concurred that the site is not eligible for listing on the NRHP in a letter to Atlantic dated November 2, 2015. A copy of that letter was provided in a supplemental filing on

November 13, 2015 (FERC Accession Number 20151113-5192). Because the newly recorded site is not eligible for listing on the NRHP, it

is not considered a “historic property”. The location of the site is depicted in Figure 1-1.

Figure 1-1 depicts the boundaries of the South Rockfish Valley Rural Historic District, Elk Hill

historic house and farm complex, and other nearby historic sites relative to the Spruce Creek

Route Variation and corresponding segment of the proposed route. The boundaries for the sites

as depicted on the figure were obtained from the site files maintained by Virginia Department of

Historic Resources.

Table 1-1 is an updated resource impact comparison table for the Spruce Creek Route Variation

and corresponding segment of the proposed route. The table indicates crossings of two

previously recorded aboveground historic sites for the Spruce Creek Route Variation, and one

previously recorded site for the corresponding segment of the proposed route.

Question Number: 1

Question Subpart: c

Question:

Regarding the Spruce Creek Route Variation that was filed by Atlantic on March 10, 2016:

c. Describe whether construction of either the proposed route or the Spruce Creek

Route Variation would adversely affect historic properties. When considering the

South Rockfish Valley Rural Historic District, specify which contributing historic

properties would be adversely affected and the possible effects to the District’s

eligibility status.

Response:

Both the proposed route and Spruce Creek Route Variation cross the South Rockfish Rural

Historic District (62-5119). The proposed route crosses approximately 0.6 mile of the district

near the intersection of Rockfish Valley Highway and Glenthorn Loop, passing through

approximately 0.4 mile of forested land and 0.2 mile of agricultural land. The route variation

crosses approximately 1.9 miles of the district on the north side of Beech Grove Road and both

the east and west sides of Rockfish Valley Highway. The route variation mostly crosses

agricultural lands within the district.

Neither the proposed route nor the route variation has been fully surveyed for cultural resources

across the district. 3 Consequently, insufficient information is available at this time to assess

potential effects on the district due to construction of the Project. Based on observations to date

from public roads in the district, as well as information from desktop sources, including the

NRHP nomination form for the district, construction of the pipeline along either route is not

expected to result in the loss of the overall integrity of the district in Atlantic’s view. 4 No

structures within the district would be modified or removed as a result of the Project along either

route. Construction along the proposed route could alter existing viewsheds within the district

due to tree clearing, but no significant impacts on viewsheds from existing historic structures

within the district are anticipated, as discussed in more detail below.

Construction activities along either route could result in visual, auditory, or atmospheric (dust)

impacts due to operation of equipment, but these impacts would be temporary and limited to the

period of construction. Dust impacts would be mitigated through implementation of Atlantic’s

Dust Control Plan, which was filed with Atlantic’s Application on September 18, 2015 and

updated in a supplemental filing on July 18, 2016 (FERC Accession Numbers 20150918-5212

and 20160718-5164). Blasting is not anticipated in the vicinity of either route where the routes

3 To date, landowners along the proposed route where it crosses the district have denied permission to survey. Field surveys along the route

variation are not anticipated. 4 While there are no previously recorded archaeological sites along the routes, it is not known if archaeological remains associated with the

district are present along either route. Atlantic will conduct an archaeological survey along the proposed route across the district as

permission to survey from affected landowners is obtained.

cross the district based on review of the Soil Survey Geographic Database (SSURGO). Soils

along the routes across the district either do not contain near surface bedrock, or the near surface

bedrock is classified as paralithic (soft), which would not likely require blasting.

Following installation of the pipeline, the temporary construction corridor would be restored and

the permanent easement maintained as described in Atlantic’s Application, which was filed on

September 18, 2015 (see Resource Report 1; FERC Accession Number 20150918-5212). During

operations, there would be no visual evidence of the pipeline in agricultural areas and limited

visual evidence of the pipeline in forested areas in the maintained permanent easement across the

district.

Potential Visual Effects on Individual Structures within the District near the Proposed Route:

Wintergreen Country Store (62-0117): The proposed corridor crosses Rockfish Valley

Highway (Route 151) approximately 0.16 mile southwest of the Wintergreen Country

Store building, which is listed on the NRHP and is a contributing element of the district.

The proposed pipeline corridor is screened by trees and therefore would not be visible

from the Wintergreen Country Store.

Elk Hill Baptist Church (62-5020): This circa 1900 historically African-American

church is located approximately 0.15 mile from the Project corridor and has an

unobstructed view across fields/pasture towards the proposed route. No visual impacts to

this site are anticipated because the proposed route would be restored to agricultural

production following installation of the pipeline in this area. Information obtained from

the Virginia Department of Historic Resources indicates that this resource is not eligible

for the NRHP.

Potential Visual Effects on Individual Structures within the District near the Route Variation:

River Bluff (62-0088): The Spruce Creek Route Variation passes approximately 0.1 mile

south of River Bluff, a circa 1785 Georgian farmhouse, expanded circa 1805, that is

listed on the NRHP and is a contributing element to the district. The route variation

corridor could be viewed towards the south and southwest from the site. However, the

construction corridor would pass through pasture and cropland and no permanent changes

to the vegetation or landscape would be expected in this area.

Atlantic anticipates filing a complete report on the district, including an assessment of potential

Project effects associated with the proposed route, in October 2016.

Question Number: 3

Question Subpart: N/A

Question:

Provide the Bachman’s sparrow and Cerulean warbler habitat desktop assessment for North

Carolina.

Response:

Bachman’s Sparrow (Aimophila aestivalis)

Bachman’s sparrow is a nondescript bird species well-known for its elusiveness and distinct,

sweet song (VDGIF, 2015). The sparrow is large, appearing reddish brown overall, but streaked

with grey, brown, and black on its back and lacking wing bars. Its belly is whitish and un-

streaked, and its head has a rusty brown crown stripe and eye line. The species is difficult to

distinguish physically from other sparrows, and is best identified by its habitat and song rather

than appearance (Poston, 2008). The bird often exhibits terrestrial movements, including

hopping and running, rather than flying (USFWS, 2015). Bachman’s sparrow prefers open pine

woodland habitats with open mid-story canopies and dense patches of grassy ground vegetation,

where they can forage for plant seeds and arthropods (Meyer, 2006; USFWS, 2015). In North

Carolina, species abundance is linked to the availability of longleaf pine stands (Poston, 2008;

LeGrand et al., 2015).

Bachman’s sparrow nests are difficult to locate, and little is known about reproduction. Females

build domed or arched, north-facing nests out of grasses on the ground, typically hiding them

under a bush or against a clump of grass or other concealing feature. The sparrows raise two to

three broods of three to five eggs each year, between April and August (Meyer, 2006).

Bachman’s sparrow is found primarily in the southern coastal plain in North Carolina, in an area

dominated by longleaf pine forests, through it was historically also found along the edge of the

Piedmont through the center of the State. Fire suppression along the sparrow’s historical range

has contributed to population declines (USFWS, 2015; Poston, 2008). The potential range for

the species in North Carolina includes the following three Counties crossed by the

Project: Halifax, Sampson, and Cumberland (LeGrand et al, 2015). Bachman’s sparrow was

listed as a Federal Candidate species in 1994 and is considered a Species of Concern in North

Carolina.

According to North Carolina Natural Heritage Program (NCNHP) data (2016), there is one

documented occurrence of Bachman’s Sparrow in vicinity of the Project area in North Carolina

(in Halifax County). The location of the occurrence is depicted in Figure 3-1, which is provided

in Q3 Attachment 1; the figure is marked “Contains Privileged Information – Do Not Release”.

A desktop habitat assessment for Bachman’s sparrow was conducted for the Project in Halifax,

Sampson, and Cumberland Counties. As a part of this assessment, potential habitat within the

Project area was identified using GAP and community vegetation data. Table 3-1, which is

provided as Q3 Attachment 2, identifies habitat type, milepost range, and length of habitat

crossed along the Project centerline, and provides centroid mileposts for habitats within

construction workspace that are not crossed by the centerline.

Cerulean Warbler (Dendroica cerulea)

The cerulean warbler is a 4.5 inch long neotropical songbird (USFWS, 2006). Males have a sky-

blue head, back, and breast band; darker gray wings with two white bars; black-streaked backs

and sides; and a white throat and belly. Female coloration is a muted bluish-green above and

white below, with two white wing bars. In North Carolina, the warblers breed in the mountains

during the summer, raising one brood with 3-5 eggs, and then migrate to the tropics for

winter. The birds build small, open cut nests high off the ground and away from the tree trunk,

using materials such as bark, grass, and lichen. Cerulean warblers prefer tall, mature forests with

open understory, often near streams and rivers, and feed on insects high in the canopy (Audubon,

2015; Hamel, 2000).

Cerulean warblers prefer large forest patches and avoid abrupt edges between forests and open

land, which leaves the species particularly vulnerable to forest fragmentation and habitat loss

(USFWS, 2006; Hamel, 2000). The species can be found in the western edge of North Carolina,

but cerulean warblers also have been reported and are assumed to breed in several Counties in

northeastern North Carolina, including two Counties (Halifax and Northampton) which are

crossed by the Project (Audubon, 2015; LeGrand et al., 2016; eBird, 2012). Cerulean warblers

are considered a Special Concern species in North Carolina.

According to NCNHP data (2016), there are two known occurrences of cerulean warbler in or

near the Project area in North Carolina (both in Halifax County). The locations of these

occurrences are depicted in Figure 3-2, which is provided in Q3 Attachment 1; the figure is

marked “Contains Privileged Information – Do Not Release”.

A desktop habitat assessment for cerulean warblers was conducted for the Project in Halifax and

Northampton Counties. As a part of this assessment, potential cerulean warbler habitats within

the Project area were identified using GAP and community vegetation data. Table 3-2, which is

provided as Q3 Attachment 3, identifies habitat type, milepost range, and length of habitat

crossed along the Project centerline, and provides centroid mileposts for habitats within

construction workspace that are not crossed by the centerline.

Question Number: 6

Question Subpart: N/A

Question:

Provide a table (similar to table 128-1) that identifies the construction and operational impacts on

small, medium, and large trees within the MNF, GWNF, and BRP.

Response:

Similar to the DR128-1 response, Atlantic based its assessment of the acreages and sizes of trees

that will be cleared within the pipeline construction and permanent rights-of-way on Federal

lands on a desktop analysis using 2015 Project-specific aerial photography and recent satellite

photography. Atlantic measured the length of crossing for stands of large, mature trees, what

appeared to be stands of younger trees (as compared to mature trees), and small trees primarily

found in recently cut-over areas or fields in transition back to forest. Large trees for this analysis

were considered to be anything over roughly 50 feet in height with a mature spreading crown,

while medium trees were considered to be younger trees generally found in previously cut-over

areas exhibiting even-age growth patterns, and in plantation plantings specifically planted by or

for forest products companies. Small trees were those located in fields or tree plantations that

varied in height from small to large saplings. The results of the analysis are presented by

segment in Table 6-1.

Question Number: 7

Question Subpart: N/A

Question:

Provide a table (similar to table 128-2) that identifies the miles of recently harvested, early/mid

seral, and late seral forest within the MNF, GWNF, and BRP.

Response:

Similar to the DR128-2 response, Atlantic based its assessment of the miles of recently harvested

forest, early/mid seral forest, and late seral on Federal lands on a desktop analysis using 2015

Project-specific aerial photography and recent satellite photography. Recently- harvested forest

lands (i.e., cleared within the last few years) and early seral forest lands are not crossed by the

proposed route on Federal lands. Mid-seral stands were identified as generally ranging from

thinner to full stands without evidence of logging roads, but with noticeably shorter and younger

trees. Mid-seral stands were infrequent and only found on the GWNF. The majority of all

Federal lands crossed are composed of late seral forest, which consisted of mature mixed

deciduous and mixed coniferous trees. The results of the analysis are presented in Table 7-1

below.

Question Number: 8

Question Subpart: N/A

Question:

Atlantic filed updated tables, figures, and maps on July 18, 2016. In its response to a June 13,

2016 data request (#120, filed on July 1, 2016), Atlantic stated it would reduce its permanent

right-of-way to 53.5 feet on U.S. Forest Service (USFS) lands. Clarify if the tables that were

filed on July 18, 2016 reflect the reduced permanent right-of-way on USFS lands.

Response:

The reduced permanent right-of-way width of 53.5 feet on U.S. Forest Service lands was used to

calculate the impacts in the tables filed on July 18, 2016 and the table provided with the response

to Question 5 of this filing.

Question Number: 10

Question Subpart: a

Question:

Regarding revised appendix 8J (Recreation Areas, Scenic Byways, and Special Interest Areas

Crossed by or Within 0.25 Mile of the Atlantic Coast Pipeline and Supply Header Project):

a. Based on Atlantic’s project mapping, there are portions of the MNF and GWNF

that are not crossed by the pipeline centerline but would be affected by temporary

construction workspace and/or the permanent right-of-way and are not listed in appendix

8J. For example, between AP-1 mileposts 71.6 and 72.0, the construction workspace

would occur on USFS lands; however, impacts are not disclosed in appendix 8J. Provide

a revised appendix 8J that includes impacts associated with the construction workspace

and/operational right-of-way, even if the centerline does not cross USFS lands.

Response:

Atlantic assumes that FERC’s comment in this question is based on review of the proposed

pipeline route and construction workspace relative to digital data layers for USFS land crossings,

rather than parcel lines, which are more accurate. In some cases, depending on the data set used

for review, it appears that a portion of the construction corridor is located on Federal lands when

the corridor, including associated workspace, is actually located on privately owned parcels

adjacent to Federal lands. With this in mind, Atlantic notes the following:

Between approximate AP-1 mileposts 71.6 and 72.0, the proposed construction

corridor, including associated workspace, crosses a privately owned parcel

(Project Tract ID 05-001-C010) that abuts land within the MNF (Project Tract ID

05-001-C006). The entire construction corridor, including workspace, is located

on private land in this area.

Between approximate AP-1 mileposts 76.1 and 76.2, the proposed construction

corridor, including associated workspace, crosses a privately owned parcel

(Project Tract ID 05-001-E036) that abuts land within the MNF (Project Tract ID

05-001-E041). The entire construction corridor, including workspace, is located

on private land in this area.

At approximate AP-1 milepost 101.5, the proposed construction corridor,

including associated workspace, crosses two privately owned parcels (Project

Tract IDs 38-056 and 38-058) that abut land within the GWNF (Project Tract ID

36-016). The entire construction corridor, including workspace, is located on

private land in this area.

Between approximate AP-1 mileposts 102.4 and 102.5, the proposed construction

corridor, including associated workspace, crosses a privately owned parcel

(Project Tract ID 36-070) that abuts land within the GWNF (Project Tract ID 36-

015). The entire construction corridor, including workspace, is located on private

land in this area.

At approximate AP-1 milepost 116.4, the proposed construction corridor,

including associated workspace, crosses two privately owned parcels (Project

Tract IDs 07-001-A009 and 07-001-A010) that abut land within the GWNF

(Project Tract ID 07-001-AR1). The entire construction corridor, including

workspace, is located on private land in this area.

The proposed construction corridor relative to parcel boundaries is depicted on the set of updated

construction alignment sheets that Atlantic filed on July 29, 2016 (FERC Accession Number

20160729-5108). The following alignment sheet numbers correspond to the areas referenced in

the bullet points above: 93 and 94, 100, 138 and 139, 139 and 140, and 157.

a The mileposts used in the FERC Application, which was filed on September 18, 2015 (FERC Accession Number 20150918-5212),

were based on three-dimensional changes in topography along the proposed pipeline routes. In areas where a pipeline route has changed due to the adoption of an alternative, the mileposts in the affected area have been scaled to account for the resulting

difference in the length of the route. The straight-line distance between consecutive mileposts as indicated or depicted in tables and

figures in this filing may be greater than or less than 5,280 feet. The mileposts should be considered as reference points only. b The table includes the permanent easement, temporary workspace, and additional temporary workspace. The table does not include

access roads.

Question:

With respect to the use of existing, replacement of existing, or construction of new microwave

towers, please address the following:

a. While general locations have been provided (#99, January 29, 2015 supplemental

filing), provide the locations based on distance and direction to the nearest project

milepost or the location and distance to the nearest above ground project facility;

b. While the need for modifications have been identified for most sites (#130, July 1,

2016 supplemental filing), verify the types of modifications needed for all final

sites;

c. Identify the construction and operational impacts, by land use type, resulting from

use, replacement, or construction of microwave towers; and

d. Identify if any special interest areas (conservation easements, forests, parks,

scenic byways, wetlands, cultural sites, etc.) would be affected and how Atlantic

would avoid, reduce, or mitigate for these impacts.
