DEPARTMENT OF DEFENSE
Department of the Navy
Record of Decision for the Development of Facilities in San
Diego/Coronado, CA To Support the Homeporting of One Nimitz-Class
Aircraft Carrier
Pursuant to section 102(2) of the National Environmental Policy Act
(NEPA) of 1969 and the Council on Environmental Quality regulations
implementing NEPA procedures (40 CFR 1500-1508), the Department of the
Navy announces its decision to implement the preferred alternative
presented in the Final Environmental Impact Statement (FEIS) to comply
with the 1993 Base Realignment and Closure (BRAC) directive from
Congress to close Naval Air Station Alameda and relocate ships
currently homeported there to fleet concentrations in San Diego and in
the Pacific Northwest. Affected ships include two Nimitz-class aircraft
carriers (CVNs), one of which will be realigned to the San Diego area
and is the subject of this decision.
A Notice of Intent was published in the Federal Register in July
1993, indicating that the Navy would prepare a Draft Environmental
Impact Statement (DEIS) for the Development of Facilities in San Diego/
Coronado to Support the Homeporting of One Nimitz-Class Aircraft
Carrier. A scoping meeting was held in August 1993, in Coronado,
California. In May 1995, the DEIS was distributed to federal, state and
local agencies, elected officers, special interest groups, and
interested individuals. A public hearing was held on June 7, 1995 in
Coronado. Oral and written comments and Navy responses were
incorporated into the FEIS which was distributed to the public for a
review period that ended on December 8, 1995.
The proposed action includes six separate construction projects for
facilities and infrastructure necessary to support one CVN and preserve
the existing capacity to accommodate one transient CVN at Naval Air
Station North Island (NASNI). Homeporting a CVN will require: (1)
Dredging of the carrier berths and turning basin, and the San Diego Bay
channel (consisting of the inner channel and the outer channel); and
(2) constructing a bay fill area, a carrier wharf, propulsion plant
maintenance facilities, and support utilities during the next five
years.
The carrier berths and turning basin will be dredged to a depth of
-50 feet below Mean Lower Low Water (MLLW), the inner channel will be
dredged to -47 feet MLLW, and the outer channel will be dredged to -55
feet MLLW. The outer channel extends south from Point Loma for 2.2
miles until the natural water depth reaches -55 feet MLLW. A total of
approximately 9 million cubic yards (CY) of sediments will be dredged
and disposed of at several locations. Of that amount, 70,000 CY
adjacent to the existing quaywall has been found unsuitable for ocean
disposal and will be used as backfill in the bay fill area. In
addition, approximately 40,000 CY of sediment dredged from the rock
dike foundation and 150,000 CY of sediment dredged from an eelgrass
mitigation site will also be used as backfill in the bay fill area.
Bioaccumulation studies indicated that approximately 932,000 CY of
dredged material located in the berthing area are suitable for ocean
disposal and will be disposed of at the U.S. Environmental protection
Agency approved Ocean Disposal Site (LA-5), located approximately 5
miles southwest of Point Loma. The remaining dredged material of
approximately 7.86 million CY are suitable for beach nourishment. This
material will be deposited nearshore in water depth ranging between -20
and -30 feet MLLW at four severely eroded beaches in San Diego County.
These beaches include: (a) Imperial Beach which will receive
approximately 1.7 million CY, (b) Del Mar and (c) Oceanside, which will
receive approximately 2.46 million CY each, and (d) Mission Beach,
which will receive approximately 1.24 million CY of the dredged
material. The exact disposal quantities and locations are subject to
approval and permitting by the U.S. Army Corps of Engineers (COE).
The San Diego Association of Governments (SANDAG) is attempting to
obtain funding to supplement available Navy military construction
funding in order to place dredged material directly onto eroded
beaches. In the event that federal, state, or local funding becomes
available in time to meet dredging schedules, dredge material
determined suitable for beach nourishment by the COE would be placed
directly onshore at five beach sites located in San Diego County. These
five beaches were analyzed during the EIS process and have been
determined to be suitable for onshore beach nourishment. These beaches
are not suitable for nearshore placement of dredged material because of
sensitive
[[Page 65641]]
marine resources. Under this contingency, the total of beach quality
materials would be deposited at nine sites, both nearshore and on the
beach. The exact disposal quantities and locations are subject to
approval and permitting by the COE.
A 13.4 acre bay fill area will be constructed to provide adequate
land space for carrier maintenance and support functions that need
access, laydown, or staging room. This area will also accommodate a
boatyard, a cleared security area, requisite fire lanes, and sufficient
space for pier crane operations including the movement of towed
aircraft to and from the carrier. A carrier wharf adjacent to the bay
fill area will be constructed to provide the necessary berthing spaces
and onshore support facilities, including electrical power, steam,
water, sewage, and oily waste offloading. A 14 acre near-shore site for
eelgrass mitigation will be dredged between the low tide line and -5
feet MLLW along the western shore at NASNI.
Three propulsion plant maintenance facilities will be constructed
to provide depot-level maintenance of CVN propulsion plant systems and
components in the San Diego area. These facilities are: (1) The
Controlled Industrial Facility which will be used for the inspection,
modification and repair of radiologically controlled equipment and
components associated with naval nuclear propulsion plants; (2) The
Ship Maintenance Facility which will house the machine tools,
industrial processes, and work functions necessary to perform
nonradiological depot-level maintenance on CVN propulsion plants; and
(3) The Maintenance Support Facility which will house the central area
for receiving, inspecting, shipping, and storing materials, and for
personnel support spaces. Construction of these three facilities will
involve demolition of two historic seaplane hangars.
Impacts to water quality, air quality, benthic organisms, marine
and natural resources will briefly occur during dredging and disposal
activities and construction of the shore facilities. These impacts,
however, are not considered significant within the context of the
project location and with implementation of specific mitigation
measures described herein.
While the environmental analysis conducted during the EIS process
concluded that there would be no significant impacts associated with
this project, several topics of concern were identified, including
traffic congestion, dredging, and dredge material disposal.
In accordance with the Clean Air Act and General Conformity Rule
requirements, an air quality review has been conducted for the proposed
projects. it has been determined that the proposed action is in
compliance with 40 CFR Part 63 (Determining conformity of General
Federal Actions to State or Federal Implementation Plans) and satisfies
the requirement of Section 176(c) of the Clean Air Act (42 USC 7506).
Accordingly, the proposed action conforms to the state implementation
plan's purpose of eliminating or reducing the severity and number of
violations of the national ambient air quality standards and achieving
expeditious attainment of those standards.
Section 404 of the Federal Water Pollution Control Act (FWPCA)
requires authorization from the COE for the discharge of dredged
material into the waters of the United States. Section 404 regulations
prohibit the use of any disposal site in open water when its use would
result in adverse effects on water quality, shellfish beds, fisheries
and wildlife, or recreational areas. The Navy has determined that the
proposed dredging would not have significant impacts and has applied
for a Section 404 permit for this project.
Section 401 of the FWPCA requires that any party proposing to
engage in an activity which may affect water quality must obtain state
water quality certification. Certification will not be granted unless
it has been determined that the proposed activity will not violate
state water quality standards. The Navy has applied for a Section 401
permit from the California Regional Water Quality Control Board.
In accordance with the Coastal Zone Management Act, the Navy has
requested and received concurrence with its determination of coastal
zone consistency for the CVN homeporting project from the California
Coastal Commission.
Pursuant to Executive Order 12898 on Environmental Justice,
potential environmental and economic impacts on minority and low-income
persons and communities were assessed. Any impacts caused by the CVN
homeporting project will be experienced equally by all groups within
the overall regional population. Because no long-term negative
environmental impacts are expected from the proposed action, no
particular minority or low income segment of the population would be
disproportionately affected. There is not anticipated to be any
likelihood for minority or low income individuals to be subjected to
adverse environmental or health risks.
In accordance with the National Historic Preservation Act, the Navy
has signed a Memorandum of Agreement which stipulates the mitigation
required for the demolition of two seaplane hangars.
The Navy has also concluded that there are no historic properties
at the dredge or disposal sites.
Comments Received on the FEIS
Ten comment letters were received following publication of the
FEIS. Several of these letters contained substantive comments which are
addressed below. Others reiterated comments which were previously
submitted and which have been addressed in the FEIS, or which were
beyond the scope of this EIS.
The U.S. Environmental Protection Agency responded supporting the
project, concluding that the Navy had been responsive to the Agency's
concerns.
The U.S. Fish and Wildlife Service (FWS) responded concurring with
the analysis contained in the EIS and with the mitigation plan
established for the burrowing owl.
The City of Coronado expressed support for homeporting the CVN
addressed in this project, however the City is concerned about the
impact on Coronado of all Navy projects in the area. The City requests
the Navy agree to take action on several measures the City believes
would ease the impacts of Navy-related projects in the area. The Navy
has met with City representatives and has found significant areas of
cooperation and agreement, including the following specific actions:
Use of an existing parking lot on NAS North Island
property for use by Navy members and government employees whose
automobiles do not meet criteria for general access to the base. This
lot is intended to reduce parking congestion on city streets near the
base. The lot's only restriction is to limit vehicles to 30 days of
continuous use. The Navy will investigate the legal impacts of
eliminating even the 30 day restriction.
The Navy is willing to seek funding for a new entrance to
NAS North Island, at the end of Third Street in Coronado, in
conjunction with construction of a new commissary planned for 1997.
Barging equipment and material rather than trucking it
through Coronado is a major consideration for the construction
contracts to be awarded for this project. In its requests for proposals
from prospective contractors, the Navy specified alternate
transportation as a consideration for contract award. The Navy has
elected to
[[Page 65642]]
award those contracts on the basis of ``best value'' rather than
``lowest price'' partly in order to encourage this more expensive, but
less intrusive method of transportation. Specific transportation plans
will be presented to the City of Coronado subsequent to contractor
selection.
Free passenger ferry service exists now between downtown
San Diego and NAS North Island. Additional service to the north side of
San Diego Bay is on track to begin in July 1996. A new pier will be
constructed and a parking lot designated at the Antisubmarine Training
Center in San Diego Harbor's West Basin. Initial service will include a
100-space parking lot, to be expanded to 300 spaces as passenger volume
increases. Shuttle service from the North Island ferry terminal to work
sites on base is already in place.
Park and Ride sites at Imperial Beach and NAS Miramar are
also being negotiated. Key here is identification of sites which are
convenient to users. Other actions have been implemented to complement
this measure, including prime parking spaces reserved for car pools,
institution of van pools, guaranteed rides home for car and van pool
riders as well as discounted mass transit fares.
Comments were also received expressing concern that the FEIS did
not adequately address cumulative impacts associated with future
replacement of North Island's two remaining conventionally powered
aircraft carriers and other BRAC related actions. Chapter Six of the
FEIS addressed cumulative impacts in quantitative detail, when
practiable, for past, present and future projects at North Island and
in the San Diego area.
Future Navy projects will be the subject of independent NEPA
analysis. The cumulative impacts of past and present projects coupled
with the CVN homeporting projects have not been determined to be
significant.
Mitigation
The following mitigation measures will be employed to ensure
minimization of environmental impacts associated with dredging and
disposal operations: (1) Compliance with the permit conditions
established by the COE, the California Regional Water Quality Control
Board, and the California Coastal Commission which regulate dredging
operations and define dredge sediment disposal locations; (2) adherence
to the ``no barge overflow'' requirement; (3) adherence to a dredge and
disposal monitoring plan for testing and evaluation of water quality
parameters, selected chemical contaminants and measures of turbidity in
the water column; (4) use of precision navigational equipment at both
the dredging and disposal sites; and (5) placement of all dredged
material suitable for beach nourishment nearshore for the protection of
severely eroded beaches or a combination of nearshore and onshore
disposal as previously described.
Traffic and socioeconomic impacts associated with the proposed CVN
homeporting at NASNI are not significant in context because there have
historically been three conventionally powered aircraft carriers (CVs)
homeported at NASNI. A CVN has a personnel complement of approximately
102 personnel more than that of a CV. The depot-level maintenance
facilities would increase personnel complement to an average of 750
personnel for a six-month maintenance availability period every 24
months. However, comparing the full-buildout year of 1999 with the
baseline year of 1992 indicates there will be an overall decrease of
330 personnel.
Construction of the 13.4 acre bay fill area will result in the
elimination of 13.4 acres of intertidal and shallow water subtidal
habitat, including 3.9 acres of eelgrass located in the nearshore area.
Mitigation will include the creation of 14 acres of new bay bottom,
establishment of 8 acres of eelgrass and the creation of fish
enhancement structures in the tidal area. Additionally compensation
will include the relocation of burrowing owls from the mitigation area
to other areas and the placement of clean sand from the mitigation site
at two areas on NASNI to enhance habitat for the California least tern
and Western snowy plover. Placement of the clean sand will not occur
during the California least tern or the Western snowy plover nesting
season. Further compensation for the plant species Nuttall's lotus and
coast wooly-head at the mitigation site includes the removal and
relocation of the top 6 inches of soil containing seeds from these
plants, to another location, free from disturbance at NASNI. Impacts to
nesting great blue herons, snowy egrets, and black-crowned night herons
at the new maintenance facility site will be compensated by
establishing replacement habitat at a site where there would be fewer
long-term impacts by NASNI activities.
