PLUM ISLAND ANIMAL DISEASE CENTER
PLUM ISLAND
NARRATIVE STATEMENT AND SUPPLEMENTAL INFORMATION
August 29,2012
GENERAL DESCRIPTION
The Plum Island Animal Disease Center(PIADC) ferry terminal facilities are located on the
south end of Plum Island, Assessor Map 1000-132-1-30. The waterfront is approximately 1,250
feet of wharf and terminal ferry landing facilities, built originally by the US Army in the early
1900's and later transferred to the Department of Agriculture. Plum Island, and the PIADC, is now
owned and operated by the United States Government's Department of Homeland Security. Plum
Island is a secured Federal facility, on land owned entirely and solely by the Federal Government.
There are no public trust issues associated with this site. Public access is prohibited and actively
enforced by armed guards.
The Plum Island Harbor facilities are at the southerly end of the island. The terrain is
generally flat in the area of the harbor infrastructure with gently sloped surrounding terrain and
mostly paved over sandy gravel earthen material operational surfaces built up landward of the
bulkhead wharf facilities to support ferry operations of a semi-industrial transportation hub nature.
The top elevation of the ground surface behind the bulkhead in the project area is approximately 10
feet and is at or above the Coastal Erosion line as typically applied to Town of Southold coastal
sites. The Coastal Erosion limit line cuts across the entrance channel 300 feet south of the work
area and all aspects of this project are landward of it. The developed nature of this shoreline is
industrial in nature, paved and substantially protected. There is no tidal wetland vegetation on the
work site and no submerged aquatic vegetation in the adjacent near shore waters.
This project is the restoration of one section of the steel pile sheet bulkhead at and the east
ramp landing facilities. The scope of work for this project will be undertaken in one construction
contract.
One element of the work is to install a new steel sheet pile bulkhead immediacy seaward of
the existing bulkhead, in the area of and immediately adjacent to and east of the Plum Island's ferry
landing ramp in the east side of the harbor. This bulkhead suffered from extensive corrosion and
material failure. The tie-back system is corroded and deteriorated substantially and the sheets have
been damaged by the wear and tear of ferry operations and the relentless exposure to marine waters.
The new bulkhead will be set, seaward of the existing steel sheet pile system which will remain, but
cut-off to act as toe stabilization of the new bulkhead. The sheet piling will be backfilled with
crushed stone so as to provide lateral stability to protect the existing sheets from further surface
erosion and oxidation. The damaged section of the existing bulkhead, in effect, will be buried. All
of this work will be seaward of the high tide line.
The other major element of this project is to install a new, heavy duty vehicle ramp just to
the east of the existing ramp along the same section of the bulkhead. This ramp facility will be pile
mounted to eliminate settlement due to heavy loads.
This supplemental narrative has been prepared in accordance with the requirements of State
and Federal permit agencies and the Town of Southold's Ordinance No. 6, 2004, and the Local
Waterfront Revitalization Program related to docks and shorefront improvements. This project site
is landward of the Coastal Erosion limit line. This project is exempted from provisions of the NYS
Coastal Management Act and is so listed in Appendix D. Pertinent factors for consideration under
Section 661 of the NYS Department of Environmental Conservation regulations for Tidal Wetlands
and adjacent areas are addressed herein but the emphasis is that neither tidal wetlands nor SAV
exist in or immediately adjacent to the work site and no impact to those resources, if they exist
nearby, will result from the project. The proposed work falls within the scope of the US Army
Corps of Engineers Nationwide Permit No. 3.
PROJECT PURPOSE
This existing bulkhead system was built approximately 40 years ago. The system has
corroded and deteriorated under climatic conditions and routine wear and tear and must be
oversheeted in order to provide the PIADC facility with viable, structurally sound vehicle loading
slips at Plum Island for essential transportation of materials, equipment and personnel on a daily,
all-weather basis.
ADJACENT PROPERTY OWNERS
The Federal Government owns Plum Island in its entirety. The nearest adjacent property is
the tip of Orient Point almost a mile to the west which is also owned by the Federal Government
and utilized for the point of access for primary electrical and water service to Plum Island.
PHOTOGRAPHS
Photographs of the project site, as released by the Department of Homeland Security, are
attached herewith.
PROJECT ALTERNATIVES
There are only three real options to pursue at this time to maintain the operational efficiency
and capacity of the transportation system.
• Do nothing
• Repair and restore the existing facilities, as is,or
• Replace and modify the facilities in some way
During the underwater diving visual inspection two years ago, holes were observed in the
steel sheeting near the point of embedment indication substantial loss of section and structural
stability. The existing facilities have been burdened with vehicle loads beyond original
expectations. The "do nothing" option is not considered viable or appropriate because the existing
bulkhead is in such condition that failure to repair and protect the structure will necessitate the
discontinuance of its use in the near future. Collapse or failure of the bulkhead would close the east
ferry slips.
2
The second option is very limited. The scour damage to the bulkhead runs for the westerly
so 1 foot or so of the steel sheeting. There is no good, cost effective method of repairing 40 year
old corroded steel in an underwater marine exposure without driving new steel sheeting or pouring
new concrete with that in mind. Over sheeting becomes the most economically feasible option.
The third option is complete replacement of the facilities. This would be the most costly
and would require the ferry operations to be out of the west slip for the longest period of time and
for both reasons, represents a hardship. Pursuing this course of action would however, yield a more
or less maintenance free operation for decades. The new ramp structure will be mounted so as to
avoid potentially damaging pavement surcharge loads to the bulkhead backfill. The new bulkhead
would have a tieback anchor system.
SEQUENCE OF WORK
As mentioned in the introductory paragraph, this project is to restore the bulkhead and ramp
at the east ferry ramp landings at Plum Island in accordance with guidelines set forth by the State of
New York DEC and the Town of Southold ordinance No. 6, 2004.
With regard to the scope of work for this project in Plum Island east harbor, the sequence of
work will be as follows:
➢ The work area will be prepared, including pavement removal and excavation of existing
gravely, sandy backfill to clear the way for new repair and restoration construction.
➢ Obstructions will be removed as necessary to make way for the layout of the new work.
It is envisioned that the ferry landing ramp sheet pile bulkhead walls will be installed
utilizing the following general sequence and methodology.
➢ The marine contractor will arrive by barge with deck-mounted crane, push or tug boat and at
least one work boat. Ground equipment will be on the barge or be trucked onto the site and
delivered to Plum Island on the ferries.
➢ The existing rumps, supports and fenders / dolphins, if necessary, will be removed to make
way for the installation of the scour wall.
➢ The new sheeting will be installed while the ramp is out of position. These sheet piles will
be driven at the general locations shown in the application drawings immediately in front of
the existing wall. Crushed stone backfill will be placed between the new and existing
bulkhead sheets.
➢ The hinged rump will be reinstalled to match pre-existing conditions.
➢ The gravely backfill will be excavated down to approximately the mean high water line to
minimize backfill loads on the existing bulkhead.
➢ Bulkhead tie-back anchor rods will be cut and re-installed to the new anchor system driven
behind the concrete wall.
➢ Wood fender piles and the wood wale system on the top of the existing bulkhead will be re-
attached as necessary to complete this phase of the installation.
REQUIREMENTS OF SECTION 97-25 OF THE WETLANDS LAW
The permittee acknowledges that the validity of this permit is subject to the approval of
other governmental or municipal authorities.
3
The permittee does, by the acceptance of this permit, assume all responsibility for
operations undertaken pursuant to this permit, and shall take all precautions for the prevention of
injuries to persons and property resulting from such operations.
The permittee gives consent to the State or Town and its officers, employees and agents to
enter upon the premises where such operations are being conducted to make such inspections to
determine whether said operations are being conducted in conformity with the permit; such
inspections are governed by the operating rules and regulations of the U.S. Department of
Homeland Security, PIADC.
The permittee will notify the Trustees in writing one week prior to initiation of any and all
operations, and likewise the NYS DEC on forms provided in the permit.
The permittee will notify the Trustees and State DEC in writing upon completion of
operations such that the site can be inspected for issuance for a certificate of compliance.
In response to Town of Southold Local Law Number 6, the following additional information
is offered.
1. Permits for the work are being applied for through the Town and NYS DEC. This
project is exempted from a coastal zone consistency determination by the NYS DOS
and this has been confirmed with the DOS. This project is covered by the US ACOE
Nationwide Permit No. 3.
2. Any facilities constructed of wood, will be of sturdy, durable and stable materials; in
all likelihood, CCA pressure-treated Southern Yellow Pine or Greenheart piles, with
one or multiple 1" minimum galvanized bolts per connection and wrapped with
galvanized cables, if required for clustered piles.
3. It is respectfully requested that the use of CCA pressure-treated piles (as an option to
Greenheart piles) and timbers be approved for this project if Greenheart is
unavailable or they are determined to be the most advantageous option to PIADC.
4. The 15-foot property line clearances specified in this paragraph should not be an
issue; the entire island is owned by the Federal Government.
5. Upon receipt of the permit (if required) for this project, appropriate permit numbers
and/or certificates will be affixed to the most seaward face of the center bumper for
identification from the water.
6. There will be no modifications to the ramps, decking and railing. One area light on
Plum Island will be moved to be clear of the tie-back anchors as will the electrical
service panel.
7. There is no need to provide adequate room for a five-foot passage way on the
upland. Terminal facilities are Federally owned and operated, subject to the security
provisions of Homeland Security installations. Public access is prohibited.
US Army Corps of Eneineers—
This project is covered under Nationwide Permit #3 of the US Army Corps of Engineers for
repair and restoration of the bulkhead,basically"in kind and in place".

NYS DEC Tidal Wetlands Regulations—Sections 661.5 and 661.9
This project represents the repair of existing, long-standing bulkhead and a new ferry landing
at Plum Island with no adverse environmental impacts and no further encroachment into tidal waters.
This facility was most recently re-built in the mid-1990's and has been routinely maintained since
that time.
There are no tidal wetlands vegetation within several hundred feet of the site and no SAV in
the waters adjacent to the wall. A ferry landing on the waterfront is considered to be generally
compatible use in an adjacent area(AA) with a permit being required under Section 661.5 (b) (1), 15
and 24. This project however, is repair and restoration of existing facilities with no new
encroachment.
Under Section 661.9, the standards for issuance of permits of NYS DEC regulations, the
following are considered to be pertinent considerations. The policies are created to preserve and
protect tidal wetlands and prevent their despoliation and destruction and that regulated activities will
not have an undo adverse impact on the present or potential value of the affected tidal wetlands.
This new ramp and bulkhead restoration project for the ferry terminal is compatible with
public health and welfare policies of the State specifically referenced under Section 661.6.
➢ The project complies with development restrictions contained in Section 661.6 as this is repair
and restoration of an existing, long-standing facility that has previously undergone review by
the Department in rendering previous permits. Furthermore, the project supports the
continued operation of a long-standing, high-priority, secured Federal installation and the
waterfront ferry facility structure is compatible with the use of the site, zoning and the long-
standing use of the site.
➢ This project will not have an undo or adverse impact on the present or potential value of
nearby tidal wetlands vegetation. There are no tidal wetlands in the Plum Island terminal
harbor; all of the terminal shoreline is developed shorefront. Construction materials will be in
accordance with the NYS DEC standards and Town of Southold regulations and laws as
previously addressed.
Town of Southold—LWRP.NYS DOS Coastal Consistency
These application documents include a copy of the Town of Southold Local Waterfront
Revitalization Program (LWRP) work sheet addressing what would customarily be pertinent sections
of the plan. The NYS DOS has suggested that since the Coastal Management Act does not apply to
this project, neither does the LWRP. Nonetheless, the following policies from the Local Waterfront
Revitalization
Program would normally be appropriate and have been identified as pertinent to this application and
the reason for consistency associated with this project is outlined in each respective case.
Policy 2 —Water Dependent Uses — This project is to retain a fully functional water dependent use
of a ferry terminal facility for an essential transportation to and from this site.
Policy 5 — Use of Existing Developed Shorefront — This project will be primarily to repair and
restore existing shore / ferry interface structures, clear of sensitive habitat or tidal wetlands and
make them safe and reliably usable in all weather conditions.
Policy 7 — Significant Fish & Wildlife Habitat— Protection of significant fish and wildlife habitat
has been considered in the development of this project layout and the waters around Plum Island are
classified as essential fish habitat, however, the actual terminal is an industrial facility in a man-
made harbor, not representative of desirable natural habitat. In any case, these facilities will be
restored in kind.
Policy 8 — Protection & Preservation of Habitat — Protection and preservation of habitat has also
been considered in this project and the terminal facility is being kept to its minimal configuration
consistent with standards of the industry and restrictions set forth in the Wetlands Law, No. 6, 2004
set forth by the Town of Southold. The ferries will operate at the same location and within the
same footprint as the current operation. There are no significant changes to the dimension or
configuration of the bulkhead and ramp facilities.
Policy 11 — Minimize Damage to Natural Resources - The bulkhead repair and restoration project
has been laid out in the same footprint so as to be consistent with and so as to minimize impact to
natural resources as identified in Policy 7 above. There is no sensitive fringe wetlands growth and
there is no submerged aquatic vegetation in the sub-tidal zone where the work is to take place.
Policy 14—No Measurable Increase in Flooding- This project consists of repairs of ferry terminal
facilities that will in no way adversely affect water flow and circulation in the harbors flooding
potential of the area. Flood levels all around Plum Island are dictated by water levels in Gardiners
Bay and Block Island Sound and these structures will have no adverse influence on those flood
levels.
Policy 15 —No Dredging— Dredging is not required in this project. The waters in this small man-
made harbor is appreciably deeper off shore and the ferry arrival and departure maneuvering tends
to keep the finer-grained sediments from accreting at the ramp landing sites of the proposed work.
Policy 19— Impact on Public Access— There is no public access to or usage of lands at this site;
there is no intertidal zone. Thus, public access to the State's waters is not possible at Plum Island
because of the design of the ferry terminal facilities and site security requirements. Plum Island is a
secured Federal research facility where recreation or unsecured public access is not allowed; access
is,in fact,prohibited in the interest of national security and the health and welfare of the public.
Policy 20 — Public Trust Compatibility with Existing Adjoining Properties and Land Uses- Public
Trust compatibility to existing adjoining properties and land uses has also been considered but is
not relevant in this project.
Policy 21 — Water Dependent Recreation — This project is consistent with water-dependent uses
opportunities policies set forth in this section. The facilities will continue to be used for essential
transportation at the ferry terminal.
Policy 24 —Scenic Resources. Impairment or Loss - This policy is intended to prevent impairment
or loss of scenic resources. The construction of the ramp facilities will not represent any new
encroachment or structure which would create a loss of scenic resources. These terminals are
industrial, working waterfront sites. The elevated northerly bulkhead section on Plum Island will
be only a couple of feet higher than the existing facility and will not even be noticeable from the
waters off-shore which are a minimum of a quarter-mile distant.
6
Policy 25 — Enhance Overall Scenic Quality - The new ramp facilities will be consistent with the
scenic quality of the area and prevent loss of scenic resources as described in Policy 24 above. The
refurbished facilities will hardly be noticeable in context with the other existing facilities which
dominate the shore of the harbors and again,these are industrial nature working waterfront sites and
the repair work is confined to the developed shorefront.
Policy 44 — Preserve and Protect Tidal Wetlands — There is no tidal wetlands on this project site.
While the terminal facilities abut dune and tidal wetlands vegetation areas, this project will have no
adverse impact on wetlands vegetation which exists elsewhere in and beyond the harbor facilities.
SUMMARY
This project is to restore a longstanding bulkhead at and adjacent to the east ramp and install
a new vehicle landing ramp and associated facilities for the US Department of Homeland Security
at Plum Island. A copy of all US Army Corps of Engineers, NYS DEC and Town of Southold
applications are attached as substantiation for this project. The Corps has indicated that ramp repair
and restoration work may proceed under Nationwide Permit No. 3. This project complies with
applicable standards of the New York State Coastal Management Act (although not required to do
so), Town of Southold Local Ordinance No. 6, 2004 and Local Waterfront Revitalization Program
and is a presumptive compatible use under NYS DEC Regulations Part 661; its approval is
respectfully requested.
