3j. Comments:
No impacts to SX11 were previously proposed (it is beneath the path of an HDD). However, DENC determined that placement of permanent culvert is
required there to facilitate future access to that portion of the easement. Similarly, revised impacts to SX16 are needed for placement of permanent
culvert. The revised impacts needed at SX17 will result from relocation of this previously -permitted crossing, such that proposed utilities can be
avoided at its original location.
E. Impact Justification and Mitigation U
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
SX11 and SX16 crossings utilize wing walls to minimize permanent impacts. SX17 crossing utilizes a box culvert to minimize impacts.

Dear Ms. Knudsen and Mr. Lawler:
Subject: Federally Listed Species Assessment, Dominion Energy North Carolina T-072 Natural
Gas Pipeline Replacement Project, Buncombe County, North Carolina
On July 7, 2020, we received a letter (via e-mail) from you requesting our review and comments
on the subject project. Included with your letter was a copy of the Protected Species Assessment
for the project. We originally met with you, representatives from Dominion Energy North
Carolina (DENC), and the US Army Corps of Engineers on February 28, 2018 to discuss the
project and potential alignment of the replacement pipeline. We have reviewed the information
you presented and are providing the following comments in accordance with the provisions of
the National Environmental Policy Act (42 U.S.C.§4321 et seq.) (NEPA); the Fish and Wildlife
Coordination Act, as amended (16 U.S.C. 661-667e), and section 7 of the Endangered Species
Act of 1973, as amended (16 U.S.C. 1531-1543) (Act).
According to the information that you presented, DENC is proposing to replace an existing
natural gas pipeline with a new 11.5-mile segment of 12-inch diameter steel natural gas pipeline.
The pipeline is proposed to begin at Duke Energy’s Asheville Energy Plant located in Arden,
North Carolina, and end near the intersection of US Highway 23 and NC Highway 112 in Enka
Village, North Carolina. Based on the proposed alignment, the pipeline will cross beneath the
French Broad River at three locations. Two crossings of Interstate 26 are also proposed, along
with a crossing of the Blue Ridge Parkway (BRPW) and Mountains to Sea Trail. Horizontal
directional drilling (HDD) will be used at these crossing to avoid impacts. The proposed natural
gas transmission line will result in thirty stream crossings and fourteen wetland crossings.
Construction of the pipeline will result in temporary impacts during trench excavation, and
maintenance of some portions of the corridor will result in permanent conversion of forested
wetlands. The pipeline will be located within a new 50-foot wide permanent easement, with
additional required temporary workspace. Phase 1 of the project, which will entail installation of
approximately 0.8 mile of the new pipe, roughly from Sand Hill Road to a point north of Country
Ms. Knudsen/Mr. Lawler – S&ME 2
Meadows Drive on the east side of Hominy Creek, is scheduled to commence in November
2020. The remainder of the project (Phase 2) is scheduled to commence in March 2021.
Federally Listed Species. As indicated in your Protected Species Assessment included with
your letter, the proposed project corridor contains potential suitable habitat for northern long-
eared bat (Myotis septentrionalis) and Virginia spiraea (Spiraea virginiana), both of which are
currently federally listed as a threatened species; as well as Appalachian elktoe (Alasmidonta
raveneliana) and gray bat (Myotis grisescens) which are both currently federally listed as
endangered species. You have made a “may affect, not likely to adversely affect” determination
for each of these species and provided justification for your determination. We have reviewed
the information you presented regarding the above listed species and their habitats within the
project site. Our assessment for these species per section 7 of the Act are as follows:
Northern long-eared bat – Construction of the new 50-foot wide permanent easement and
temporary work space for the project will require the removal of about 42-acres of forest. Forest
clearing will result in the removal/loss of potential suitable summer roosting habitat for northern
long-eared bat. However, the final 4(d) rule (effective as of February 16, 2016), exempts
incidental take of northern long-eared bat associated with activities that occur greater than 0.25
miles from a known hibernation site, and greater than 150 feet from a known, occupied maternity
roost during the pup season (June 1 – July 31). Based on the information provided, the project
(which may or may not require tree clearing) would occur at a location where any incidental take
that may result from associated activities is exempt under the 4(d) rule. Although not required,
we encourage you to avoid any associated tree clearing activities during the maternity
roosting season from April 15 – October 15; and especially during the period of June 1 –
July 31 when pups are typically non-volant.
Virginia spiraea – Though Virginia spiraea once occurred throughout the area, the population
that once occurred along Hominy Creek is believed to be extirpated. Currently, the species is
known to occur in only a few areas in Buncombe County. No populations of Virginia spiraea are
known to occur within the project corridor. S&ME personnel conducted surveys for this species
at stream crossing locations and in areas of suitable habitat. According to the Protected Species
Assessment, pockets of habitat occur in the project area however no individuals of Virginia
spiraea were observed. For this reason, you have made a “may affect, not likely to adversely
affect” determination for this species and we concur with your determination.
Appalachian elktoe – Appalachian elktoe occurs in the French Broad River and has been recently
found in close proximity to the project corridor. Construction of the proposed pipeline will
require three crossings of the French Broad River. To avoid impacts to the French Broad River,
DENC is proposing to install the new gas pipeline under the river bed using HDD. Your “may
affect, not likely to adversely affect” determination for Appalachian elktoe is based on the
proposed use of HDD at all French Broad River crossing locations. We commend DENC for
using HDD for these and other stream crossing locations. However, we recommend the
following additional measures be implemented into the project plans to ensure that impacts to the
French Broad River and Appalachian elktoe are completely avoided:
1.Develop a monitoring plan to be used during the HDD installation. An observer(s)
should be stationed on the river to follow the drill as it bores under the river bed to watch
Ms. Knudsen/Mr. Lawler – S&ME 3
for evidence of potential frac-out (e.g., bubbles, slurry discharge). If evidence of frac-out
is observed, operations should cease until further investigation demonstrates or measures
are taken to ensure a frac-out will be avoided.
2.Establish a contingency plan to be executed should a frac-out or slurry discharge to the
river occurs during HDD installation. The plan should contain steps to be taken if a frac-
out occurs to minimize any adverse effects to aquatic resources.
3. If a frac-out occurs, this office should be contacted immediately to assess the potential
impacts to Appalachian elktoe.
4.Ensure that construction of drilling pits are located so that sediment or accidental slurry
spills will not reach surface waters. Adequate sediment and erosion control measures
should be installed and maintained until drilling pits are closed out and stabilized.
5.Develop a monitoring plan that includes periodic inspections of stream crossing locations
to assess for destabilization of stream banks. The work sites should be monitored at least
every 3 months during the first 24 months and annually thereafter. Moreover, we
recommend the development of a riparian monitoring and maintenance program that
would outline procedures for the prompt stabilization of streambanks near the utility
crossing (should any streambank erosion or destabilization occur) throughout the life of
this project.
With the implementation of these additional measures, we believe the potential effects to
Appalachian elktoe from project activities will be minimized to a discountable level and we can
concur with your “may affect, not likely to adversely affect” determination for this species.
Gray bat – As mentioned in the Protected Species Assessment, a segment of the project will be
constructed within ½-mile of a known gray bat colony. Because the project will require some
forest clearing for the new easement, the project could result in the removal of a minor amount of
potential foraging habitat. However, 1) no suitable roosting habitat was observed within the
proposed easement; 2) a majority of the pipe will be installed in areas that are already cleared of
woody vegetation; and, 3) efforts will be made to schedule a majority of the clearing outside of
April 15 - October 15, during the period when the bats are expected to be more active. For these
reasons, we concur with your “may affect, not likely to adversely affect” determination for gray
bat.
Additionally, you have made a “no effect” determination for all other federally listed species
known to occur in Buncombe County. We concur. For this reason, and given the conclusions in
the preceding species determinations/assessments, we believe the requirements under section 7
of the Act are fulfilled. However, obligations under section 7 of the Act must be reconsidered if:
(1) new information reveals impacts of this identified action that may affect listed species or
critical habitat in a manner not previously considered, (2) this action is subsequently modified in
a manner that was not considered in this review, or (3) a new species is listed or critical habitat is
determined that may be affected by the identified action.
Wetland/Stream Protection and Erosion Control - We strongly recommend that stringent
measures to control erosion be implemented prior to any ground disturbance and these measures
should be maintained throughout project construction. Excavated material should not be
stockpiled in an area or manner that would allow the material to erode into surface waters.
Ms. Knudsen/Mr. Lawler – S&ME 4
Grading and backfilling should be minimized, and existing native vegetation should be retained
(if possible) to maintain riparian cover for fish and wildlife. Disturbed areas should be
revegetated with native grass and tree species as soon as the project is completed. Ground
disturbance should be limited to what will be stabilized quickly, preferably by the end of the
workday. Natural fiber matting (coir) should be used for erosion control as synthetic
netting can trap animals and persist in the environment beyond its intended purpose.
Fertilizers and pesticides should not be used near streams.
Project Recommendations - We are concerned about the introduction and spread of invasive
exotic species in association with the proposed project. Without active management, including
the revegetation of disturbed areas with native species, project corridors will likely be sources of
(and corridors for) the movement of invasive exotic plant species. Exotic species are a major
contributor to species depletion and extinction, second only to habitat loss. Exotics are a factor
contributing to the endangered or threatened status of more than 40 percent of the animals and
plants on the Federal List of Endangered and Threatened Wildlife and Plants.1 It is estimated
that at least 4,000 exotic plant species and 2,300 exotic animal species are now established in the
United States, costing more than $130 billion a year to control.2 Additionally, the
U.S. Government has many programs and laws in place to combat invasive species (see
www.invasivespecies.gov). Specifically, Section 2(a)(3) of Executive Order 13112 - Invasive
Species (February 3, 1999) directs federal agencies to “not authorize, fund, or carry out actions
that it believes are likely to cause or promote the introduction or spread of invasive species in the
United States or elsewhere.” Despite their short-term erosion-control benefits, many exotic
species used in soil stabilization seed mixes are persistent once they are established, thereby
preventing the reestablishment of native vegetation. Many of these exotic plants3 are also
aggressive invaders of nearby natural areas, where they are capable of displacing
already-established native species. Therefore, we strongly recommend that only species native
to the natural communities within the project area be used in association with all aspects of this
project.
We also recommend that seeds for native plants that are beneficial to pollinators be included in
the erosion control seed mixes. Pollinators, such as most bees, some birds and bats, or other
insects, including moths and butterflies, play a crucial role in the reproduction of flowering
plants and in the production of most fruits and vegetables. Over 75 percent of flowering plants
and about 75 percent of crops are pollinated by these pollinators. A recent study of the status of
pollinators in North America by the National Academy of Sciences found that populations of
honey bees (which are not native to North America) and many wild pollinators are declining.
Declines in wild pollinators are a result of loss, degradation, and fragmentation of habitat and
disease; while declines in honey bees has also been linked to disease. Because loss of habitat
and diminished native food sources have decreased the populations and diversity of pollinators
throughout the country, we recommend that development projects be sited in areas that are

previously disturbed (fallow fields, closed industrial sites, etc.) or sites that do not impact mature
forests, streams, or wetlands. To offset the overall impacts of development and/or to increase the
habitat and species diversity within the project area, we further recommend the following
measures be implemented into project design:
1. Throughout the site, sow native seed mixes with plant species that are beneficial to
pollinators. Taller-growing pollinator plant species should be planted around the
periphery of the site and anywhere on the site where mowing can be restricted during
the summer months. Taller plants, not mowed during the summer, would provide
benefits to pollinators, habitat to ground-nesting/feeding birds, and cover for small
mammals. Low-growing/groundcover native species should be planted in areas that
need to be maintained. This would provide benefits to pollinators while also
minimizing the amount of maintenance, such as mowing and herbicide treatment.
Using a seed mix that includes milkweed species (milkweed is an important host plant
for monarch butterflies) is especially beneficial. The following Web site provides a
comprehensive list of native plant species that benefit pollinators:
http://www.xerces.org/wp-content/uploads/2014/09/MidAtlanticPlantList_web.pdf
Additional information regarding plant species, seed mixes, and pollinator habitat
requirements can be provided upon request. Attachment 1 and Attachment 2 of this
letter include a sample upland and riparian mix that can be used in conjunction with a
fast growing erosion control seed mix for overall soil stability and pollinator benefits.
We also offer our assistance with developing seed mixes that can be used in
conjunction with fast growing erosion control seed mix for overall soil stability and
pollinator benefits.
2. Implement an easement mowing and maintenance program that restricts mowing
during the summer months. Mowing at the site should be restricted to the smallest
area possible to manage the edges of the easement for early successional habitat. We
recommend that DENC evaluate its maintenance plan to target ecological/habitat
benefits to other wildlife species, especially pollinators and birds that require early
successional habitats. One of the best ways to accomplish this objective is to use
Integrated Vegetation Management (IVM) practice using low-volume herbicide
applications when planning management activities. Pollinator nest sites in ROWs
managed with IVM practices have been found to contain about 30% more pollinator
nesting sites and species richness than traditionally mowed maintenance areas. Aside
from removing problem vegetation, the primary focus should be placed on
establishing compact flowering shrubs and managing for native grasses and
wildflowers. The overall objective is to reach a sustainable level of grasses, forbs, and
flowering shrubs (wherever feasible) throughout the project area.
3. Provide nesting sites for pollinator species. Different pollinators have different
needs for nesting sites. Therefore, we recommend managing the pipeline easements in
a manner that creates or maintains a diverse array of habitats to accommodate varied
pollinators, from hummingbirds to butterflies to bees. Hummingbirds typically nest in
Ms. Knudsen/Mr. Lawler – S&ME 6
trees or shrubs while many butterflies lay eggs on specific host plants. Most bees nest
in the ground and in wood or dry plant stems. For additional information and actions
that can be taken to benefit pollinators please visit the following Web site:

Attachment 1 – Sample Upland Meadow Seed Mix for NC Piedmont
This is an example upland pollinator seed mix that is suitable for the project site. This list is not
an all-inclusive list nor does a pollinator planting project need to include all of these species. I
can help to customize a seed mix for the project area which could decrease costs if requested.

DENC has identified two additional streams that require permanent
crossings in order to accommodate future maintenance equipment
egress/regress to isolated or otherwise not readily accessible
portions of the proposed easement. In addition, the proposed
location of one stream crossing and permanent access needs to be
shifted slightly from its originally permitted location in order to avoid a
conflict associated with the landowner's development plans for the
property.
A request for modification to the existing permit to authorize these
additional minor impacts will be submitted to NCDWR upon expiration
of the 30-day clock.
While construction of the overall project will continue in the interim,
any stream/wetland impacts resulting from with the proposed
modification request will not take place until authorization has been
formally received from NCDWR and the USACE.
