Sec LWRP Section III - Policies Pages 6 through 7 for evaluation criteria __ Yes __ No X Not Applicable This site is restricted to public access. The terminal site is visible from the water only when directly south of the line of the harbor. The only portion of the proposed work visible to any extent is the harbor from the south and at a distance; the changes in appearance will hardly be noticeable. The only land side visual access affected by this project is at the terminal site and the industrial nature of the site and ferry landing facilities will be unchanged by the repair work. NATURAL COAST POLICIES Policy 4. Minimize loss of life, structures, and natural resources from flooding and erosion. See LWRP Section III - Policies Pages 8 through 16 for evaluation criteria. Yes __ No X Not Applicable These proposed bulkhead repair and restoration will take place in the harbor and is acknowledged to be in a flood-prone area; there is little wave exposure at this site. The bulkhead has been designed to accommodate complete submersion and resist hydrostatic uplift pressures due to flooding. The project site, in fact all of the ferry terminal facilities are landward of the Coastal Erosion limit line. Policy 5. Protect and improve water quality and supply in the Town of Southold. See LWRP Section III - Policies Pages 16 through 21 for evaluation criteria. Yes __ No X Not Applicable This project will not have any affect on suitability of or availability of drinking water.

TITLE Agent DATE October 2011 BULKHEAD REPMRS AND RESTORATION U.S. DEPARTMENT OF HOMELAND SECURITY PLUM ISLAND ANIMAL DISEASE CENTER PLUM ISLAND NARRATIVE STATEMENT AND SUPPLEMENTAL INFORMATION August 24, 2011, Revised October 14, 2011 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. The Plum Island Harbor facilities are at the southerly end of the island and the terrain is also 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 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 nearshore waters. This project is the repair and restoration of one section of the steel pile sheet bulkhead at and adjacent to the east amp landing facilities. The scope of work for this project will be undertaken in two phases. The first and simplest phase of the project is the replacement of the tie-back system in the southerly section of the east harbor bulkhead. This will involve cutting out the existing steel anchor rods and driving a new anchor wall tie-back system which will consist of steel sheet piling approximately 40 feet back from the face of the steel bulkhead. These two sets of sheet piling will then be interconnected with the anchor rod system; the existing anchor rods will be removed. The second phase of the work is to install a replacement bulkhead landward of the existing bulkhead, in the area immediately adjacent to and west of the Plum Island's ferry landing ramp in the east side of the harbor. This bulkhead suffered from toe and tie-back failure several years ago and was repaired on an emergency basis. The tie-back system is corroded and deteriorated substantially and the sheets have already damaged by the previous failure. The new bulkhead will thus be set, landward of the existing steel sheet pile system which will remain, but cut-off to act as scour protection 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, in effect, will be buried. All of this work will be landward of the high tide line. Plum~d is a secured Federal facility, on land owned entirely and solely by the Federal Government. Them am no public trust issues associated with this site. Public access is prohibited and actively enforced by armed guards. The remainder of the work is to install free-standing sections of steel sheeting in front of the bulkhead at each of four landing ramp facilities; two at Plum Island and two at Orient Point. The ferry propeller thrust scour damage to the existing bulkhead is extensive. Small stones and grit from the bottom sediments have been propelled into the existing steel sheet pile wall and deteriorated the structural capabilities of this system by eating away the steel sheeting in these high thrust areas. The new independent sheets will be cantilevered sections supported by the embedded end of the sheet and backfilled with crushed stone so as to provide lateral stability to protect the existing sheets from further surface erosion and oxidation. The damaged section, in effect, will be buried. These scour walls will be driven as close as possible to the existing steel sheeting in order to avoid the necessity of altering the existing hinged ramps. The geometry of the existing slips will allow these sheets to be driven and still provide an adequate safety factory for the maneuvering and security of the ferries during the boarding and disembarking process. 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 25 years ago. The system has corroded and deteriorated under climatic conditions and routine wear and tear and must be repaired in order to provide the PIADC facility with viable, structurally sound 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. 2 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 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. Another option is to repair the bulkhead as it exists today. This is probably the most cost- efficient and best option for Plum Island. This section of the bulkhead failed in 2008 and was repaired on an interim basis. The sheets were deformed during the breach. The cap which was also deformed as the bulkhead moved, creates a situation where the ultimate structural integrity of the bulkhead is in serious question. It is felt that the damaged section of the bulkhead should be cut off after a new bulkhead is driven behind it. Thus, no work is done waterward of the high tide line. A new bulkhead "anchor" will be driven approximately 40 feet back from the face of the harbor and the two bulkheads will be inter-connected which a tie-back anchor rod system. The anchor wall will extend toward the southerly end and the tie-back system for the southerly section of this bulkhead will be replaced rentilizing the existing sheet piling and wale. The tie-back and anchor system for the southerly section of the bulkhead is marginal. Since the age of the remaining facilities around the site varies, but the southerly bulkhead section requiring the new tie-back and anchor system is one of the newer sections utilizing PZ22 sheets, it was felt that the system could and should be reutilized to get the full structural service life out of the steel components and will be the most cost-effective for the PIADC operation. 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 service for the longest period of time and for both reasons, does not represent the most prudent or cost-beneficial options. SEQUENCE OF WORK As mentioned in the introductory paragraph, this project is to repair and restore the bulkheads at and adjacent to 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 the bulkhead repairs in Plum Island east harbor, the sequence of work will be as follows: The existing excavated work area will be enlarged, 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 layont of the new work. 3 The gravel.y 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. With regard to the steel sheet pile bulkhead "backwall" adjacent to the ferry landing slip, the scope of work will be as follows: Existing sheets will be cut off from their anchor system to clear the way for driving the PZ35 sheets which will be driven at the alignment shown in the application drawings pending encounters with sub-surface obstructions. Backfill will be excavated from behind the steel sheets to minimize active pressures on the structure. The existing sheets will be cut off above the existing wale to clear the way for the new bulkhead wale system to be installed. The new bulkhead wale system will be installed behind, landward of, the existing sheet piling and the anchor rods will be secured to the new anchor wall as shown in the application drawings. The wood wale bracing for the fender piles which are to remain, and cap system will be installed. Existing fender piles will be re-attached to the new bulkhead and wale system. It is envisioned that the ferry landing ramp scour 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 ramps, supports and fenders / dolphins, if necessary, will be removed to make way for the installation of the scour wall. The new scour protection sheeting will be installed while the ramp is out of position. These sheet pile scour walls will be driven at the general locations shown in the application drawings. Crashed stone backfill will be placed between the scour wall and existing bulkhead sheet. The hinged ramp will be reinstalled to match pre-existing conditions. 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. 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. 4 The permittee gives consent to the 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. The permittee will notify the Trustees in writing upon completion of operations such that the site can be inspected for issuance for a certificate of compliance. In response to Local Law Number 6, the following additional information is offered. 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. 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. 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. The 15-foot property line clearances specified in this paragraph should not be an issue; the entire island is owned by the Federal Government. 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. 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. 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 Engineers - 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". 5 NYS DEC Tidal Wetlands Regulations - Sections 661.5 and 661.9 This project represents the repair of existing, long-standing 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 1,000 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 bulkhead repair and 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 terminals are 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. 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 repair and restore bulkheads at and adjacent to the east 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.
