1985, EPA Final Determination for the
Bayou aux Carpes site, issued under
Section 404(c) of the CWA. An
exception was provided in the original
1985 restriction for discharges
associated with routine operation and
maintenance of the Southern Natural
Gas Pipeline Company pipeline.
Subsequently, the exception was
extended to cover minor discharges
from emergency maintenance and
relocation of a portion of another
existing pipeline operated by Shell
Pipeline Corporation. Both the original
exception and the subsequent extended
coverage were allowed based on
determinations that the proposed
activities associated with these existing
linear service utilities would be unlikely
to result in unacceptable adverse effects
to the Bayou aux Carpes CWA Section
404(c) site. This action approves
coverage under the same exception for
the work requested by Entergy, which
will also entail minor temporary
impacts to the subject wetlands.
The August 18, 2014, request by
Entergy, and other background
information are available at: https://
www.regulations.gov (Docket No. EPA–
R06–OW–2014–0569).
Background
Section 404(c) of the CWA authorizes
the EPA to prohibit, deny, restrict or
withdraw the use of any defined area as
a disposal site for dredged or fill
material if the discharge will have
unacceptable adverse effects on
municipal water supplies, shellfish beds
and fishery areas (including spawning
and breeding areas), wildlife, or
recreational areas. The U.S. Army Corps
of Engineers (Corps) authorizes
thousands of CWA Section 404 permits
every year and the EPA works with the
Corps and applicants to resolve
environmental concerns. Since the
passage of the CWA in 1972, the EPA
has finalized Section 404(c) prohibitions
or restrictions only 13 times. The use of
this authority has typically involved
major projects with unacceptable
impacts on some of America’s most
ecologically valuable waters.
On November 15, 1985, EPA
published a CWA Section 404(c) Final
Determination (50 FR 47267) restricting,
with three exceptions, future discharges
of dredged or fill material to wetlands
in the Bayou aux Carpes site. The CWA
Section 404(c) action was based upon a
thorough record of investigations,
including field surveys, remote sensing
and other technical analyses conducted
by three EPA facilities, the U.S. Fish
and Wildlife Service, the National Park
Service and the Louisiana State
PO 00000

University Center for Wetland
Resources.
The 1985 EPA Bayou aux Carpes
CWA Section 404(c) Final
Determination included three
exceptions. The first of the original
three approved exceptions is for
discharges associated with the
completion of a specific design option
for the Corps’ Harvey Canal—Bayou
Barataria Levee Project, which was
never constructed. The second
exception is for discharges associated
with routine operation and maintenance
of the Southern Natural Gas Pipeline.
The third exception provides for
possible future EPA approved habitat
enhancement activities. The EPA
determined that these three types of
activities would be unlikely to result in
unacceptable adverse effects to the
aquatic environment, as long as they
were performed in accordance with any
specified conditions and complied with
any permit conditions that might be
imposed by the Corps through the CWA
Section 404 permit process. A provision
was also included to allow other
interests to petition the EPA for
reconsideration if, in the future, other
activities were to be proposed for public
benefit which would result in only
minor impacts.
There has been only one major
modification to the EPA’s 1985 decision
to restrict discharges into the wetlands
of the Bayou aux Carpes site. The
modification was granted to the Corps
in 2009 in association with the
construction of flood risk reduction
upgrades following Hurricane Katrina.
On November 4, 2008, the Corps
requested that the Bayou aux Carpes
CWA Section 404(c) designation be
modified to allow construction of a
floodwall along Bayou Barataria and
tying it into the planned West Closure
Complex, as part of the post-Hurricane
Katrina upgrades known as the Greater
New Orleans Hurricane and Storm
Damage Risk Reduction System Project.
This work was but a small part of the
larger effort to reduce flood risks to the
250,000 people living on the west bank
of the Mississippi River and to
infrastructure supporting the greater
New Orleans area by building a more
resilient and reliable storm damage and
risk reduction system, as directed by
Congress.
In addition to that modification of the
1985 EPA Bayou aux Carpes CWA
Section 404(c) Final Determination, the
EPA has considered very few requests
for coverage under the original
exceptions. In 1992, Shell Pipeline
Corporation requested permission to
allow the discharge of dredged and fill
material effecting approximately 0.43
E:\FR\FM\12DEN1.SGM

acres of wetlands in the restricted site
in connection with a proposed below
ground pipeline relocation. This work
was necessary to facilitate the
enlargement of a federal hurricane
protection levee and to remedy the
emergency reconstruction of a leaking
temporary by-pass pipeline segment. In
addition, future routine operation and
maintenance activities associated with
this pipeline were requested to be
excluded from the CWA Section 404(c)
restriction. After notifying interested
parties of the request via Federal
Register publication and coordinating
with the Corps and other agencies, the
EPA granted the requests, publishing
the decision at 57 FR 3757 (January 31,
1992). The EPA concluded that
relocating the pipeline to non-wetlands
was infeasible from the perspectives of
engineering and public safety, the work
would have only minimal and
temporary effects on the wetlands at
issue and the work was essentially the
same as that envisioned under the
second exception included in the 1985
Final Determination.
Over the years, additional requests for
modifications have been the subject of
initial analyses by the EPA. In each of
those cases, however, the petitioners did
not complete the analyses required for
an agency decision.
Proposed Activities
The Barataria to Alliance
Transmission Line was constructed in
the 1960’s by Entergy’s predecessor,
Louisiana Power & Light. Of the 74,012
foot total transmission line length, an
11,543 foot section and 15 towers are
within the 120 foot right-of-way that
runs through the southern portion of the
Bayou aux Carpes CWA Section 404(c)
site. The distribution line and 15
wooden single poles course through
approximately 3,415 feet within a ten
foot right-of-way section of the Bayou
aux Carpes site.
On August 18, 2014, Entergy
petitioned the EPA for an exception to
cover anticipated temporary impacts to
a total of 0.003 acres (approximately
1.35 cubic yards) of wetlands resulting
from operation and maintenance
activities for portions of an existing
transmission line and portions of a
distribution line located within the
Bayou aux Carpes Section 404(c) area.
Entergy’s request involves activities
required for preventative maintenance
and inspections as required by Federal
Energy Regulatory Commission
regulations, North American Electric
Reliability Corporation regulations and
Entergy’s guidelines and procedures.
The activities subject to the request are
projected to temporarily effect no more
VerDate Sep<11>2014
16:57 Dec 11, 2014
Jkt 235001
than 0.003 acres of the protected
wetlands during the remaining 50–60
years of expected facility life.
Conclusion
Following receipt of the request by
Entergy, the EPA conducted a technical
review of the projected wetland
impacts, considered the applicable
programmatic requirements,
coordinated with other resource
agencies, and provided an opportunity
for public review. We received no
comments from the public and one
statement of federal agency support for
the proposed EPA action to approve the
Entergy request, which came from the
Jean Lafitte National Historical Park and
Preserve.
As a result of our analyses, the EPA
has approved the request by Entergy to
perform limited operation and
maintenance activities on the specified
power lines located in the Bayou aux
Carpes CWA Section 404(c) site in
Jefferson Parish, Louisiana. The EPA has
approved coverage for the continued
operation and maintenance of these
lines under an exception provided in
the October 16, 1985 EPA Bayou aux
Carpes Final Determination as amended.
The 1985 CWA Section 404(c) EPA
decision to restrict the use of the Bayou
aux Carpes site for the discharge of
dredged or fill material included three
exceptions. The second exception
covered discharges associated with the
routine operation and maintenance of
portions of the Southern Natural Gas
Pipeline that crossed the site. An
exception was subsequently extended to
Shell Pipeline Corporation in 1992 for
work on another pipeline that predated
the 1985 EPA restriction. We have now
extended coverage under that same
exception in the Final Determination as
amended to Entergy for the purposes
specified in the August 18, 2014
request. These activities are similar to
those previously approved for the
Southern Natural Gas pipeline and the
Shell pipeline in that the electrical lines
existed prior to the 1985 EPA decision
and the maintenance work is expected
to incur only minor and temporary
wetland impacts.
This decision reflects a unique set of
circumstances and does not have any
bearing on any other CWA Section
404(c) determinations, amendments, or
modification requests. Each CWA
Section 404(c) designation represents a
unique situation that responds to a
specific set of parameters unlike any
other.
This CWA Section 404(c) approval
covers discharges expected to impact no
more than a total of 0.003 acres of
wetlands (approximately 1.35 cubic
PO 00000
Frm 00011
Fmt 4703
Sfmt 4703
73889
yards) in the Bayou aux Carpes CWA
Section 404(c) site from dredged or fill
material associated with ongoing
Entergy activities. The activities are
restricted to those included in the
August 18, 2014, request by Entergy to
the EPA.
The approved work includes such
routine maintenance as inspecting
towers and lines for damage, replacing
tower coatings, reapplying cathodic
protection on foundations and anchors,
cutting vegetation away from overhead
lines, limited spot treatments with
approved herbicides, and other
emergency repairs including tower
replacements in the same location.
Entergy expects that any replacement of
towers would be accomplished without
discharging dredged or fill material,
with the exception of tower structure
#31. In that instance, special procedures
should be employed whereby the old
foundations would be left in place and
the new foundations would be situated
nearby. In all cases, the access to the
site, the types of work and repair
methods, and the kinds of vehicles and
machinery to be used shall be designed
so as to avoid and minimize wetland
impacts and shall be in accordance with
the methods specified in the August 18,
2014, Entergy request.
Entergy shall be the responsible entity
for ensuring compliance with the terms
of this approval. Entergy shall be
responsible for ensuring that all
employees and contractors working
within the Bayou aux Carpes CWA
Section 404(c) site understand the terms
and extent of this approval. Any
violation of the terms of this approval
shall be reported by Entergy to the EPA
by telephone immediately upon
discovery, followed by a written report
by Entergy describing the circumstances
and ecological impacts. In this event, all
related work activities shall cease until
resolution is reached with the EPA.
Entergy shall notify Jean Lafitte
National Historical Park and Preserve
prior to each instance during which
inspections (including aerial
inspections) or operations and
maintenance work is performed within
the Bayou aux Carpes CWA Section
404(c) site. In each instance, Entergy
shall employ the least damaging
equipment and repair methods possible.
This approval does not cover any
activities that would impact wetlands in
the Bayou aux Carpes CWA Section
404(c) site associated with any
alternatives for placing the currently out
of service distribution line back into
service or to remove the 3,415 foot-long
distribution line and associated 15
wooden poles. Similarly, this approval
does not cover the deactivation of the
E:\FR\FM\12DEN1.SGM
12DEN1
73890
Federal Register / Vol. 79, No. 239 / Friday, December 12, 2014 / Notices
transmission line or the removal of the
11,534 foot-long power line and 15
transmission structures within the
Bayou aux Carpes CWA Section 404(c)
site. Such activities should be
specifically coordinated in advance
with the EPA and Jean Lafitte National
Historical Park and Preserve.
This approval does not provide
authorization under Section 10 of the
Rivers and Harbors Act of 1899 or
Section 404 of the Clean Water Act for
Entergy’s proposed discharges. Entergy
must obtain authorization from the
Corps in order to proceed with any
activities governed by these statutes at
the Bayou aux Carpes CWA Section
404(c) site. Entergy shall also be
responsible for obtaining all necessary
permits and approvals from the National
Park Service, Jean Lafitte National
Historical Park and Preserve. In
addition, Entergy shall be responsible
for obtaining any other necessary
permits, notices and approvals at all
levels of government and for conducting
all required regulatory coordination
prior to implementing any of the work
covered by this approval.
In the event that Entergy determines
that the continued operation and
maintenance activities covered by this
exception will cause or are likely to
cause unanticipated and unacceptable
adverse impacts, it shall notify the EPA.
Similarly, if the EPA determines that the
continued operation and maintenance
activities covered by this exception will
cause or are likely to cause
unanticipated and unacceptable adverse
impacts, the EPA may reconsider this
approval.

SUPPLEMENTARY INFORMATION: The Bayou aux Carpes CWA Section 404(c) site
is located approximately ten miles south of New Orleans, Louisiana, on
the West Bank of Jefferson Parish. The site includes about 3,000 acres
of wetlands subject to federal jurisdiction under the CWA. The area is
bounded on the north by the Estelle Pumping Station Outfall Canal, on
the east by Bayou Barataria (Gulf Intracoastal Waterway), on the south
by Bayou Barataria and Bayou des Familles, and on the west by State
Highway 3134 and the ``V-Levee.'' In 2009, most of the site was
incorporated into the Barataria Unit of the Jean Lafitte National
Historical Park and Preserve and the site remains subject to the CWA
Section 404(c) restrictions.
Entergy petitioned EPA on August 18, 2014, for an exception to the
October 16, 1985, EPA Final Determination for the Bayou aux Carpes
site, issued under Section 404(c) of the CWA. An exception was provided
in the original 1985 restriction for discharges associated with routine
operation and maintenance of the Southern Natural Gas Pipeline Company
pipeline. Subsequently, the exception was extended to cover minor
discharges from emergency maintenance and relocation of a portion of
another existing pipeline operated by Shell Pipeline Corporation. Both
the original exception and the subsequent extended coverage were
allowed based on determinations that the proposed activities associated
with these existing linear service utilities would be unlikely to
result in unacceptable adverse effects to the Bayou aux Carpes CWA
Section 404(c) site. This action approves coverage under the same
exception for the work requested by Entergy, which will also entail
minor temporary impacts to the subject wetlands.
The August 18, 2014, request by Entergy, and other background
information are available at: https://www.regulations.gov (Docket No.
EPA-R06-OW-2014-0569).
Background
Section 404(c) of the CWA authorizes the EPA to prohibit, deny,
restrict or withdraw the use of any defined area as a disposal site for
dredged or fill material if the discharge will have unacceptable
adverse effects on municipal water supplies, shellfish beds and fishery
areas (including spawning and breeding areas), wildlife, or
recreational areas. The U.S. Army Corps of Engineers (Corps) authorizes
thousands of CWA Section 404 permits every year and the EPA works with
the Corps and applicants to resolve environmental concerns. Since the
passage of the CWA in 1972, the EPA has finalized Section 404(c)
prohibitions or restrictions only 13 times. The use of this authority
has typically involved major projects with unacceptable impacts on some
of America's most ecologically valuable waters.
On November 15, 1985, EPA published a CWA Section 404(c) Final
Determination (50 FR 47267) restricting, with three exceptions, future
discharges of dredged or fill material to wetlands in the Bayou aux
Carpes site. The CWA Section 404(c) action was based upon a thorough
record of investigations, including field surveys, remote sensing and
other technical analyses conducted by three EPA facilities, the U.S.
Fish and Wildlife Service, the National Park Service and the Louisiana
State University Center for Wetland Resources.
The 1985 EPA Bayou aux Carpes CWA Section 404(c) Final
Determination included three exceptions. The first of the original
three approved exceptions is for discharges associated with the
completion of a specific design option for the Corps' Harvey Canal--
Bayou Barataria Levee Project, which was never constructed. The second
exception is for discharges associated with routine operation and
maintenance of the Southern Natural Gas Pipeline. The third exception
provides for possible future EPA approved habitat enhancement
activities. The EPA determined that these three types of activities
would be unlikely to result in unacceptable adverse effects to the
aquatic environment, as long as they were performed in accordance with
any specified conditions and complied with any permit conditions that
might be imposed by the Corps through the CWA Section 404 permit
process. A provision was also included to allow other interests to
petition the EPA for reconsideration if, in the future, other
activities were to be proposed for public benefit which would result in
only minor impacts.
There has been only one major modification to the EPA's 1985
decision to restrict discharges into the wetlands of the Bayou aux
Carpes site. The modification was granted to the Corps in 2009 in
association with the construction of flood risk reduction upgrades
following Hurricane Katrina. On November 4, 2008, the Corps requested
that the Bayou aux Carpes CWA Section 404(c) designation be modified to
allow construction of a floodwall along Bayou Barataria and tying it
into the planned West Closure Complex, as part of the post-Hurricane
Katrina upgrades known as the Greater New Orleans Hurricane and Storm
Damage Risk Reduction System Project. This work was but a small part of
the larger effort to reduce flood risks to the 250,000 people living on
the west bank of the Mississippi River and to infrastructure supporting
the greater New Orleans area by building a more resilient and reliable
storm damage and risk reduction system, as directed by Congress.
In addition to that modification of the 1985 EPA Bayou aux Carpes
CWA Section 404(c) Final Determination, the EPA has considered very few
requests for coverage under the original exceptions. In 1992, Shell
Pipeline Corporation requested permission to allow the discharge of
dredged and fill material effecting approximately 0.43
[[Page 73889]]
acres of wetlands in the restricted site in connection with a proposed
below ground pipeline relocation. This work was necessary to facilitate
the enlargement of a federal hurricane protection levee and to remedy
the emergency reconstruction of a leaking temporary by-pass pipeline
segment. In addition, future routine operation and maintenance
activities associated with this pipeline were requested to be excluded
from the CWA Section 404(c) restriction. After notifying interested
parties of the request via Federal Register publication and
coordinating with the Corps and other agencies, the EPA granted the
requests, publishing the decision at 57 FR 3757 (January 31, 1992). The
EPA concluded that relocating the pipeline to non-wetlands was
infeasible from the perspectives of engineering and public safety, the
work would have only minimal and temporary effects on the wetlands at
issue and the work was essentially the same as that envisioned under
the second exception included in the 1985 Final Determination.
Over the years, additional requests for modifications have been the
subject of initial analyses by the EPA. In each of those cases,
however, the petitioners did not complete the analyses required for an
agency decision.
Proposed Activities
The Barataria to Alliance Transmission Line was constructed in the
1960's by Entergy's predecessor, Louisiana Power & Light. Of the 74,012
foot total transmission line length, an 11,543 foot section and 15
towers are within the 120 foot right-of-way that runs through the
southern portion of the Bayou aux Carpes CWA Section 404(c) site. The
distribution line and 15 wooden single poles course through
approximately 3,415 feet within a ten foot right-of-way section of the
Bayou aux Carpes site.
On August 18, 2014, Entergy petitioned the EPA for an exception to
cover anticipated temporary impacts to a total of 0.003 acres
(approximately 1.35 cubic yards) of wetlands resulting from operation
and maintenance activities for portions of an existing transmission
line and portions of a distribution line located within the Bayou aux
Carpes Section 404(c) area.
Entergy's request involves activities required for preventative
maintenance and inspections as required by Federal Energy Regulatory
Commission regulations, North American Electric Reliability Corporation
regulations and Entergy's guidelines and procedures. The activities
subject to the request are projected to temporarily effect no more than
0.003 acres of the protected wetlands during the remaining 50-60 years
of expected facility life.
Conclusion
Following receipt of the request by Entergy, the EPA conducted a
technical review of the projected wetland impacts, considered the
applicable programmatic requirements, coordinated with other resource
agencies, and provided an opportunity for public review. We received no
comments from the public and one statement of federal agency support
for the proposed EPA action to approve the Entergy request, which came
from the Jean Lafitte National Historical Park and Preserve.
As a result of our analyses, the EPA has approved the request by
Entergy to perform limited operation and maintenance activities on the
specified power lines located in the Bayou aux Carpes CWA Section
404(c) site in Jefferson Parish, Louisiana. The EPA has approved
coverage for the continued operation and maintenance of these lines
under an exception provided in the October 16, 1985 EPA Bayou aux
Carpes Final Determination as amended.
The 1985 CWA Section 404(c) EPA decision to restrict the use of the
Bayou aux Carpes site for the discharge of dredged or fill material
included three exceptions. The second exception covered discharges
associated with the routine operation and maintenance of portions of
the Southern Natural Gas Pipeline that crossed the site. An exception
was subsequently extended to Shell Pipeline Corporation in 1992 for
work on another pipeline that predated the 1985 EPA restriction. We
have now extended coverage under that same exception in the Final
Determination as amended to Entergy for the purposes specified in the
August 18, 2014 request. These activities are similar to those
previously approved for the Southern Natural Gas pipeline and the Shell
pipeline in that the electrical lines existed prior to the 1985 EPA
decision and the maintenance work is expected to incur only minor and
temporary wetland impacts.
This decision reflects a unique set of circumstances and does not
have any bearing on any other CWA Section 404(c) determinations,
amendments, or modification requests. Each CWA Section 404(c)
designation represents a unique situation that responds to a specific
set of parameters unlike any other.
This CWA Section 404(c) approval covers discharges expected to
impact no more than a total of 0.003 acres of wetlands (approximately
1.35 cubic yards) in the Bayou aux Carpes CWA Section 404(c) site from
dredged or fill material associated with ongoing Entergy activities.
The activities are restricted to those included in the August 18, 2014,
request by Entergy to the EPA.
The approved work includes such routine maintenance as inspecting
towers and lines for damage, replacing tower coatings, reapplying
cathodic protection on foundations and anchors, cutting vegetation away
from overhead lines, limited spot treatments with approved herbicides,
and other emergency repairs including tower replacements in the same
location. Entergy expects that any replacement of towers would be
accomplished without discharging dredged or fill material, with the
exception of tower structure #31. In that instance, special procedures
should be employed whereby the old foundations would be left in place
and the new foundations would be situated nearby. In all cases, the
access to the site, the types of work and repair methods, and the kinds
of vehicles and machinery to be used shall be designed so as to avoid
and minimize wetland impacts and shall be in accordance with the
methods specified in the August 18, 2014, Entergy request.
Entergy shall be the responsible entity for ensuring compliance
with the terms of this approval. Entergy shall be responsible for
ensuring that all employees and contractors working within the Bayou
aux Carpes CWA Section 404(c) site understand the terms and extent of
this approval. Any violation of the terms of this approval shall be
reported by Entergy to the EPA by telephone immediately upon discovery,
followed by a written report by Entergy describing the circumstances
and ecological impacts. In this event, all related work activities
shall cease until resolution is reached with the EPA.
Entergy shall notify Jean Lafitte National Historical Park and
Preserve prior to each instance during which inspections (including
aerial inspections) or operations and maintenance work is performed
within the Bayou aux Carpes CWA Section 404(c) site. In each instance,
Entergy shall employ the least damaging equipment and repair methods
possible.
This approval does not cover any activities that would impact
wetlands in the Bayou aux Carpes CWA Section 404(c) site associated
with any alternatives for placing the currently out of service
distribution line back into service or to remove the 3,415 foot-long
distribution line and associated 15 wooden poles. Similarly, this
approval does not cover the deactivation of the
[[Page 73890]]
transmission line or the removal of the 11,534 foot-long power line and
15 transmission structures within the Bayou aux Carpes CWA Section
404(c) site. Such activities should be specifically coordinated in
advance with the EPA and Jean Lafitte National Historical Park and
Preserve.
This approval does not provide authorization under Section 10 of
the Rivers and Harbors Act of 1899 or Section 404 of the Clean Water
Act for Entergy's proposed discharges. Entergy must obtain
authorization from the Corps in order to proceed with any activities
governed by these statutes at the Bayou aux Carpes CWA Section 404(c)
site. Entergy shall also be responsible for obtaining all necessary
permits and approvals from the National Park Service, Jean Lafitte
National Historical Park and Preserve. In addition, Entergy shall be
responsible for obtaining any other necessary permits, notices and
approvals at all levels of government and for conducting all required
regulatory coordination prior to implementing any of the work covered
by this approval.
In the event that Entergy determines that the continued operation
and maintenance activities covered by this exception will cause or are
likely to cause unanticipated and unacceptable adverse impacts, it
shall notify the EPA. Similarly, if the EPA determines that the
continued operation and maintenance activities covered by this
exception will cause or are likely to cause unanticipated and
unacceptable adverse impacts, the EPA may reconsider this approval.
