Re: Case 02-T-0036 Neptune Regional Transmission System, LLC

Dear Secretary Deixler:

Enclosed please find the Second Supplement to the Application of Neptune Regional Transmission System, LLC ("Neptune RTS•") for a Certificate of Environmental Compatibility and Public Need ("Second Supplement").

The Second Supplement addresses several changes being proposed for the cable route and the direct current ("DC") to alternating current ("AC") converter station associated with the Long Island segment of the proposed transmission facility, the only segment Neptune RTS• is seeking authority to construct and operate at this time.

The changes detailed in the Second Supplement are:

A change in the undersea to upland transition (or "landfall") location from the southern terminus of the Wantagh State Parkway at Island Creek, to a location east of the Jones Beach State Park Fishing Pier near the southern terminus of the Jones Beach Causeway.

Associated with the new landfall location, approximately three miles of additional upland cable routing within the Jones Beach Causeway right-of-way, and an equivalent reduction of three miles of submarine cable routing within Hempstead Bay. Hon. Janet H. Deixler June 27, 2003 Page 2

Relocation of the DC to AC converter station from the Cedar Creek Wastewater Treatment Facility property to a location 8.7 miles north of Cedar Creek, on property to be leased from the New York State Office of Parks, Recreation and Historic Preservation at 508 Duffy Avenue, New Cassel, Town of North Hempstead.

Associated with the converter station relocation, the addition of 1.7 miles of underground cable routing within the Wantagh State Parkway right-of-way in which the DC cable will be extended and an AC cable connecting the converter station to LIPA's Newbridge Road Substation will be located.

There are no new material adverse environmental impacts associated with these changes.

Neptune representatives have consulted extensively with local residents, community groups, and civic leaders about the change in the proposed location of the converter station. The Second Supplement includes a discussion of the questions and comments raised in those consultations, along with information as to how Neptune has addressed those questions and comments.

The enclosed Second Supplement includes revised portions of the Application and supplemental materials that describe the changes and assess potential impacts associated with the changes. Except to the extent portions of the Application have been revised by the enclosed Second Supplement, the Application remains as filed in January 2002. A table of contents for the Second Supplement is also enclosed.

Notice of this filing has been published in Newsdav once a week for two consecutive weeks in compliance with 16 NYCRR § 85-2.10. Copies of this letter are being served on all parties shown on the attached list. Copies of the Second Supplement are being provided to the Long Island-based active parties, all state agency parties, and all those listed in Public Service Law § 122 (2)(a), including elected officials serving the Town of North ^empstead.

Meeting Community Concerns The following is a list of comments and questions raised at the meetings listed above. Every effort has been made to address these concerns within this Application and the applicable section is indicated following the statement of concern. Where these issues have not been addressed elsewhere, a response follows the concern.

Questions about LIPA and Long island's Energy Needs

What has LIPA said about the project and its energy plans? Neptune RTS• is proposing a project that is a perfect match with the type of facility LIPA says it needs in Long Island to handle future energy needs. According to LIPA's Energy Plan, the Authority is looking for "a new transmission line to Long Island that would accommodate the reliable delivery of products from an off-island generating facility" to help "serve its increasing load requirements." The undersea cable line that Neptune RTS• is connecting from New Jersey will fulfill this requirement. On April 10, 2003 the Planning Committee of the Nassau County Legislature held a day long public hearing on the energy needs of Long Island and what plans there are to meet them. LIPA Chairman Rich Kessel testified that an undersea cable from New Jersey to Long Island "would tremendously benefit Nassau County in many ways." Kessel continued: "Most importantly...it would give us 500 or 600 megawatts of energy from a power plant that is not on Long Island. It would add to our margins on hot summer days; it would increase our important capability and allow us to shop for cheaper electricity and not be tied to just buying whatever we need here on Long Island."

02:001412_EA01_07_02-B1132 Community Outreach.doc-6/27/2003 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Community Outreach

Will the average homeowner see a decrease in their LIPA bill? Neptune RTS will provide competively priced electricity to LEPA, who will in turn provide it to consumers over their grid. It is LIPA that determines customer rates.

Do the proposed windmills provide the same amount of energy? Only about 100MW would be produced by the wind energy project, proposed for 2007 or 2008.

Will there be rolling brownouts without more supply? It is likely. LIPA is already forced to conduct selective load shedding. As load in the region continues to grow so will challenges to providing stable, reliable power across the grid. LIPA's peak demand in summer of 2002 was 5200MW and supply was only 5600 MW. The Neptune RTS• project will provide up to 600 MW of reliable capacity.

Questions About the Link to New Jersey

What is the status of this project in New Jersey? A connector with Long Island has been widely accepted in Sayreville, N.J., a community on the Raritan River. In April, the Sayreville Borough Council gave its unanimous, bipartisan support for the River Road Redevelopment Plan, which includes as its centerpiece the construction of a converter station on 12 acres of waterfront property. The project has since received the unanimous support of the Sayreville Economic Redevelopment Authority, which is selling the property to Neptune. Is there a power plant in New Jersey? Does the originating plant bum fossil fuels? Electricity traveling on Neptune RTS• comes from the Regional PJM grid, not a specific power plant. Instead, consumers in Long Island will be provided access to a broad portfolio of generation assets found within the New Jersey, Pennsylvania, and Maryland (PJM) grid.

02:001412_EA01_07_02-B1132 Community Outreach.doc-6/27/2003 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Community Outreach

How will the electricity travel? Electricity will move safely through a solid seven-inch, DC cable buried under the sea. This cable will overcome bottlenecks in the existing, land-based electrical transmission grid, which hinders the efficient use of energy resources in Long Island and northern and central New Jersey. The cable will travel undersea from another converter station in Sayreville, New Jersey, through the Raritan Bay and the Atlantic Ocean to Hempstead Bay. It will surface in Long Island near the Jones Beach State Park Fishing Pier and will be laid beneath the right-of-way along the east side of the Jones Beach Causeway to the Wantagh State Parkway and, eventually, to the Duffy Avenue site. After DC power is converted to AC power at the Neptune RTS• facility, it will be transported in AC cables to interconnect with LIPA's Newbridge Road substation. The electricity will then run on LIPA's local distribution network.

Questions About the Converter Station and Substation

What is the purpose of the converter station? Transporting electricity in the form of DC has significant reliability and efficiency advantages. Once transported to its destination it must be converted to AC to be deliverable into the LEPA system. The proposed station is a vital link in LIPA's plans to solve growing energy shortages in its electricity transmission network. Designed by a consortium of veteran energy and construction companies, the facility will make electricity available in Nassau and Suffolk counties through reliable, efficient, and environmentally proven technology. Neptune RTS• is designed to connect communities in Long Island, in need of expanded power supplies, with surplus power available in the Mid-Atlantic States. The Long Island station will be a link in the power grid through New Jersey to the Mid-Atlantic States - the integral, off- island solution that LIPA is seeking. After DC power is converted to AC power at the Neptune RTS• facility, it will be transported in AC cables to interconnect with LIPA's Newbridge Road substation. The electricity will then run on LIPA's local distribution network.

02:001412_EA01_07_02-B1132 Community Outreach.doc-6/27/2003 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Community Outreach

What level of impact will the converter station have on the community? The converter station, to be built at 508 Duffy Avenue, will be constructed off the main road, when placed in service, will create no additional traffic to the area. The facility will have no air or water emissions, will have no moving parts except for a few fans and is designed in strict accordance with state safety and construction requirements, as well as local noise ordinances for North Hempstead.

What are the benefits to the Westbury taxpayer? Neptune RTS• has agreed to lease vacant state property on Duffy Avenue in New Cassel, located in an industrial/commercial area abutting the Wantagh State Parkway and the Long Island Railroad. It is expected that Neptune will pay at least $750,000 in taxes annually to the Town of North Hempstead and Nassau County each year. More than 65% of the annual taxes will be directed to the Westbury School District.

Why New Cassel? LIPA has identified the most beneficial locations for new electricity sources on the island, and prefer an interconnection at its existing central substation on Newbridge Road in Levittown. Neptune RTS• prefers the New Cassel site for its conversion station because the Duffy Avenue location is just 1.7 miles away from the central substation, on a tract that is tucked away from neighborhoods and commercial businesses. The site comprises a mix of vacant land and highway equipment, surrounded by trees, which will be preserved as part of the project.

Will the Newbridge Road substation be expanded? No expansion of the current land area the substation is occupying at Newbridge Road is needed by Neptune RTS•. The interconnection facilities inside the fence of the existing substation will be designed by LIPA in the future and are not part of this Application.

What is the Converter Station Site Used for Now? What changes will it mean? The proposed site is state-owned and is currently a maintenance yard for the state Department of Transportation. The property is used as a storage area for salt piles, which the

02;001412_EA01_07_02-BU32 7 Community Outreach.doc-6/27/2003 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Community Outreach agency uses to melt snow and ice on its roadways. This use will continue after the converter station is built. The Neptune RTS• proposal represents an opportunity for the community. This converter station, a $60 million investment within New Cassel, will offset residential property taxes without impacting the local quality of life. In addition, the project will create an estimated 200 local construction jobs. Unlike many industrial facilities, once operational this project will create no traffic or odors, and no air or fluid emissions. The minimal noise generated from the facility will not be noticeable, especially because it is located next to a bustling highway and is buffered with a wooded tract.

What will the impact be on real estate values to surrounding homes? The converter station is designed to be compatible with existing structures in the vicinity. The immediate area is industrial and commercial in character. Residences are north and west of the Parkway in New Cassel. It is designed to have no noise impacts on surrounding real estate and will have no discharges. Consequently, it is not expected to have a negative impact on property values.

What kind of noise will emanate from the converter station? Will the surrounding residential areas hear anything? Noise impacts from the facility are discussed in detail in Exhibit 4.13. Noise levels will comply with the Town of North Hempstead noise ordinance and will not be noticeable above existing background noise.

Will there be any odors emanating from the Station? No odors will emanate from the station. No odor-causing processes occur within the facility.

02:001412_EA01_07_02-B1132 Community Outreach.doc-6/27/2003 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Community Outreach

Is the station visible from neighboring homes or parks? What will the station look like? How much of the property will the station cover? What is the height of the station? How big is the Lot? A detailed visual analysis of the station, including simulations and architectural renderings, is provided in Exhibit 4.12. The converter station property is approximately 7 acres. The facility will cover 3.7 acres. The lot is approximately 19 acres.

Questions About Environmental Issues

Does the cable pose any danger to marine life? Will there be any disruption to the seabed, ocean bed, or habitat? A detailed discussion of impacts to marine life is included in Exhibits 4.5,4.6, and 4.8 of the original Application. Any impacts will be temporary, construction related, and not permanent.

What is being done to ensure the preservation of wetlands? In environmentally sensitive areas, the cables will either be installed clear of wetlands or buried underground by directional drilling methods. A protective barrier will separate wetlands from work areas. Once laid, the cables are maintenance-free, but will be monitored to ensure proper location and reliable operations. A detailed discussion of wetland impacts is included in Exhibit 4.7 of the original Application and in the same exhibit in this Application.

Has there been a geological survey? Only for the marine portion of the cable route. A survey of the upland cable route and converter station site will occur as part of the final facility design phase of the project.

Will a storm or high tide be a hazard to the cable? The converter station is the only portion of the project above ground, and it is located outside the 100-year and 500-year floodplains. The station is also equipped with automatic emergency cutoff so in the unlikely event that floodwaters were severe enough to effect the station, there would be no hazard to homeowners. The cable is designed for use in marine

O2:0O1412_EA01_07_02-B1132 9 Community Outreach.doc-6/27/2003 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Community Outreach environments and will be buried so it does not pose a hazard to homeowners in the event of a storm or flood. Flood zones are discussed in greater detail in Exhibit 4.7 of this report. Station control is discussed in more detail in Exhibits 4.14 and E-2 of this report, and cable design is discussed in more detail in Exhibit E-l of this report.

What are the environmental benefits to the New Cassel area and the Town of North Hempstead? Neptune RTS• technology offers numerous environmental benefits over the traditional delivery of power. This technology:

• Gives Long Island access to a variety of electric generating technologies and energy sources from off the Island

• Provides adequate power to Long Island for years to come, reducing the need to locate new power plants on Long Island

• Reduces the reliance on old, less efficient, and polluting sources of generation throughout the entire region

• Eliminates, via underwater cables, the need for high-tension wires to be constructed through local neighborhoods

• Provides additional energy to the island without the need for an additional power plant

What about existing groundwater contamination in the industrial area of New Cassel? Does the converter station have any effect on preexisting volatile organic compound (VOC) plumes in the area? No effect will occur. The industrial site "plume" is 180 feet below the surface and is east of the Wantagh Parkway and south of the LIRR tracks. The converter station is above ground, except for certain foundations and water containment facilities, and will not emit any fluids. A rainwater collection system will be incorporated in the design. A NYDEC monitoring well is currently on or near the converter station site and the results of this monitoring, together with planned geotechnical survey work, will provide information so that final design and construction plans will avoid any impact on the existing groundwater beneath the site.

02:001412_EA01_07_02-BI 132 10 Community Outreach.doc-6/27/2003 Neptune Regional Transmission System LLC Article VU Application Second Supplement June 2003 Community Outreach

Alternative Sites.

Is there an alternative site? Why can't Neptune use an alternative site? Will the cost to the rate-payer be increased with an alternative site? Alternative sites are discussed in detail in Exhibit 3 of the original Application and Exhibit 3 of this Application. Additional sites were suggested and visited. They were not found to be viable alternatives either for reasons of significant additional cost to LIPA, relative to on island generation, or lack of proximity.

Questions About Construction Issues.

What is the project timetable? Will construction be disruptive? Construction of the converter station will begin in 2004, simultaneously with the facility in New Jersey. The converter station in New Cassel should be operational by the summer of 2006. This timeline would require the submarine cable to be installed from New Jersey to Long Island by 2005-06. The installation process, from the Fishing Pier area to Duffy Avenue, would take place in the off-season months, September through May of 2005-06, to avoid peak traffic periods.

Will the bike path on Wantagh State Parkway be repaired? In those areas where there is disturbance during construction, the bike path will be restored following construction to NYSDOT-specifications and in many places will be improved. Neptune will work with the NYS Office of Parks and Recreation to finalize restoration plans for the bike path.

How long will it take to build the converter station? Approximately 18 months.

How long will it take to place the cable under the seabed? From Jones Inlet to landfall at the Fishing Pier will take less than 2 weeks.

02:001412_EA01_07_02-B1132 11 Community Outreach.doc-6/27/2003 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Community Outreach

How long will the construction on Wantagh State Parkway last and what hours will the mass construction be done? The bulk of the construction will take place from 7AM to 6PM in accordance with the Town Noise Code.

Will repairs be done on-site? Yes, although the solid state nature of the facility will not necessitate many repairs throughout its service life

How deep will the cable be under the seabed? The target burial depth for the cable is 4 feet below the seabed in most areas. Where the cable crosses navigation channels it will be buried to a depth of 17 feet below authorized channel depth agreed upon with the U. S. Army Corps of Engineers. This cable will not cross any federal channels in NY waters.

How will the underwater cable installation impact the waterways? Cable burial from land to water will employ underground drilling from upland to submarine water routes. The installation process of the underwater cable will generally employ a low-impact, water-driven installation device that simply fluidizes the sediment to allow the cable to be set at its target depth. The cables will sink by their own weight about four feet into the sea bed around the south shore and Hempstead Bay, a depth that the US Coast Guard has determined to be below the depth reached by small-boat anchors and clam fishing gear. After the installation, the seabed will rapidly return to pre-construction contours.

What size is the cable? Approximately 7 inches in diameter. The underwater trench is about 18 inches. The upland underground cable trench, which has a cement shield, will be approximately 2-3 feet.

How many undersea cables will be connected to Long Island? One DC cable, which contains a fully enclosed return conductor.

02;00U12_EA01_07_02-B1132 12 Community Outreach.doc-6/27/2003 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Community Outreach

Health and Safety Issues

What is the proximity and range of any EMF (electric and magnetic fields)? How close will the cables be on Wantagh State Parkway to any homes? A detailed discussion of EMF, including an aerial photo with EMF levels depicted, is included in Exhibit 4.14 of this report. The DC cable produces no EMF and the Converter Station will comply with the NYSPSC EMF limits.

Will the workers on-site be adversely affected? No.

Will the converter station present any unusual danger of fire? No. All materials to be used in the facility have been reviewed by the local and county firefighting departments who have concluded that there is nothing unusual present that requires special firefighting training or equipment.

General Questions

How long has Neptune RTS• been in business? Are there are comparable sites in the United States? Neptune RTS LLC was formed in 2000. The consortium of five companies participating in the project are experienced energy and construction companies with combined experience of more than 100 years. See www.Neptune RTS.com for more details on company composition. There are about 10 HVDC converter station facilities in North America. However, none are of the same modem generation of design as that which Neptune RTS is proposing. The most comparable facility in service is the Moyle Interconnector in Northern Ireland, which was placed in service January 2002.

02:001412_EA01J)7_02-B1132 13 Community Oulreach.doc-6/27/2003 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Community Outreach

Will Neptune RTS• own the cable? How long will Neptune RTS• own the cable? Neptune RTS• will own, operate, and maintain the system, including the cable. Expected equipment life exceeds 30 years.

What is Neptune's agreement with LIPA (proposed agreement)? Who will be responsible for the maintenance of the cable? Are there any guidelines for the construction of the station and cable? Neptune RTS• and LIPA have engaged in engineering and technical evaluations that began many months ago. LIPA has issued an RFP for new energy sources, including off island power and transmission lines with a preference for 2006. Neptune RTS• will most likely contract locally with a qualified firm to maintain the system. Construction will be performed in accordance with state, federal, and intemational standards of reliability and safety.

Will the converter station have any effect on cell phone usage? No. Filters are built into the facility design to prevent affects on cell phones, radios and TVs.

How much of the population on Long Island will be affected by 600MW of energy? 600,000 homes.

EXHIBIT 2 - LOCATION OF FACILITIES

2.1 Location of Neptune RTS• The location of the NeptuneRTS• Sayreville to Long Island facilities will be as previously identified with the following proposed changes:

• The cable route will be as shown on Figure 2-1. The route through New York State waters is shown in revised Figure 2-5, which reflects the revised landfall near the Fishing Pier at Jones Beach State Park.

• The cable will be buried to a depth of 17 feet below authorized depth in all federal navigation channels rather than the deeper of 6 feet beneath the seabed or 6 feet below authorized depth as originally proposed. While this modification will not require supplemental dredging within New York State waters, dredging will be required in two locations within the lower bay near the New Jersey-New York State line.

• The cable will make landfall at a point near the Jones Beach State Park Fishing Pier and then proceed north within the right-of-way (ROW) along the east side of the Jones Beach Causeway to the southern terminus of the Wantagh State Parkway, rather than at the Island Creek landfall, as originally proposed.

• The proposed location of the Long Island converter station will be on a parcel owned by the New York State Office of Parks, Recreation and Historic Preservation located at 508 Duffy Avenue in the Town of North Hempstead rather than at the Cedar Creek Wastewater Treatment Facility in the Town of Hempstead, as proposed in the first Supplement or at the Newbridge Road Substation as originally proposed. The DC cable will be located within the east side of the Wantagh State Parkway ROW north to the Duffy Avenue site. An AC cable will run south to the Newbridge Road Substa- tion also on the east side of the Wantagh State Parkway.

Landfall to the Southern Terminus of the Wantagh State Parkway Landfall at the Fishing Pier requires the addition of 3 miles of upland construction between the Fishing Pier and the original landfall at the southern terminus of the Wantagh State Parkway. Construction will take place in upland areas along the east side of the Wantagh Causeway, within the maintained right-of-way and the existing bike path to the greatest extent possible.

Duffy Avenue Converter Station The Duffy Avenue Converter Station site is located at 508 Duffy Avenue in the Town of North Hempstead, County of Nassau, Long Island, New York. The converter station site is located approximately 1.7 mile north of the Newbridge Road substation along the east side of the Wantagh State Parkway, within an industrial/commercial section of the Town of North Hempstead. The converter station site is bounded on the north by the Long Island Railroad, on the east by existing industrial development, on the south by Duffy Avenue, and on the west by Wantagh Parkway. A DOT landfill, capped in 1995, is located in the north-central portion of the site and an existing DOT storage facility occupies the southern portion of the site. The landfill was used solely for the storage of non putrescible highway waste and development will avoid the landfill area. The site contains piles of sand, soil and road debris such as brush, auto parts, and litter. A wooded area acts as a buffer between the site and the Wantagh State Parkway. The Duffy Avenue site is owned by the New York State Office of Parks, Recreation and Historic Preservation and used by the New York State Department of Transportation.

Additional Wantagh Parkway Cable Route Location of the converter station at Duffy Avenue would require installation of an additional 1.7 miles of HVDC cable, within the Wantagh State Parkway right-of-way between New- bridge Road and the Duffy Avenue Converter Station, and approximately 1.7 miles of underground AC cable to connect the converter station to the Newbridge Road substation. Under- ground HVDC and AC cables would be in separate parallel trenches for this portion of the route. NeptuneRTS• will lease the property where the Duffy Avenue Converter Station will be located from the State of New York and for the cable route will acquire easements from the State within the Wantagh State Parkway right-of-way, from the Fishing Pier landfall to the Duffy Avenue Converter Station site from the State of New York and the Town of Hempstead in the underwater lands in Hempstead Bay, and from the State in underwater lands for the remainder of the route.. Descriptions of the property in relation to other properties are contained in Exhibits 4.2 and 4.12 of this Second Supplement. As indicated in Second Supplemental Exhibit 4.14, vehicular access to the proposed facilities will make use of the asphalt driveway currently used to

A gate will restrict road access to the facility. The Duffy Avenue Converter Station and all associated equipment will be contained within an enclosure wall, and access to the Duffy Avenue Converter Station property will be restricted further by fencing. Figure 2-1 shows the revised general project area. Figure 2-3 shows the revised route to Long Island on Department of Transportation (DOT) base maps. Figure 2-5 shows the revised submarine route with the Fishing Pier landfall. Figure 2-8 provides revised aerial photographs of Long Island. Figure 2-10 presents a revised construction drawing overlain on an aerial photograph of the Duffy Avenue Converter Station site. The decision to change the location of the landfall was prompted by a desire to avoid potential impacts associated with burying the cable in areas within Hempstead Bay where elevated sediment contaminant concentrations are present and to avoid disturbing areas that have not been disturbed. The decision to change the location of the Long Island converter station from the Cedar Creek site to the Duffy Avenue site was made to address concerns raised by community residents and local government officials about locating another industrial facility at the proposed Cedar Creek location. As a consequence, Neptune reexamined the Puffy Avenue site that previously had been identified as a viable alternate site. The proposed burial depths, of four and seventeen feet, are a refinement of the original proposal that is based on guidance from the regional Army Corps of Engineers staff. Seventeen feet below authorized depth in federal navigation channels is intended to achieve compatibility with navigation maintenance, while the four feet depth elsewhere is compatible with recreational and commercial boating anchors and fishing and shellfishing activities.

2.1.2 Sayreville, New Jersey, to Newbridge Road, Hempstead, Long Island, New York The New York State portion of the New Jersey to Long Island cable route would be the same as described in the Application, up to the point within Sloop Channel in Hempstead Bay, south of Deep Creek Meadow Island and northeast of the Jones Beach State Park Fishing Piers, where the cable will turn northeast for landfall near the Fishing Pier. The landfall would be on the east side of the Jones Beach Causeway, in the Town of Hempstead, Long Island.

From the landfall point, the DC cable route would continue north within the Jones Beach Causeway ROW for approximately 3 miles to the southern terminus of the Wantagh State Parkway. The DC cable route would continue north within the Wantagh State Parkway ROW for approximately 9.2 miles to the Duffy Avenue converter station. A DC-AC converter station would be constructed on a parcel east of the Wantagh State Parkway at 508 Duffy Avenue. One 3-circuit AC cable would exit the converter station and proceed south approximately 1.7 miles, parallel to the HVDC cable, to the Newbridge Road Substation. The AC and DC cables would be installed underground using cut-and-cover and directional drilling methods, as appropriate, to minimize impacts. The upland cable would be laid 3- to 4-feet below ground surface in imported fill material in an open trench, covered with a pre-cast concrete slab that in turn will be covered with the soil that was removed during the trenching procedure. In the area, between the Newbridge Road Substation and the Duffy Avenue Converter Station, where AC and DC cables will be parallel, the cables will be laid in separate trenches with a minimum separation of 15 feet. The route would be restored to pre-construction conditions.

EXHIBIT 4 - ENVIRONMENTAL IMPACT

4.1 Introduction This Second Supplement to Exhibit 4 of the Neptune Regional Transmission System (Neptune RTS•) Application to the New York State Public Service Commission for a Certificate of Environmental Compatibility (the "Application") supplements those portions of Exhibit 4 that will be affected by the change from landfall at Island Creek to landfall at the Fishing Piers, the change from constructing the converter station at Newbridge Road to Duffy Avenue and the additional cable installation associated with the Duffy Avenue site. For consistency, this supplement uses the same section headings and figure numbers as the Application. Existing conditions, impacts, and mitigation are presented for each resource area and location. Supplements to Exhibits E-l (Electrical System Description), E-2 (Other Facilities), and E-3 (Underground Construction) also have been provided to address changes in the design and construction of the converter station and cable necessitated by the change in location.

Description of the Long Island Upland Facilities The proposed landfall at the Fishing Piers and location of the converter station facilities at a site owned by the State of New York Office of Parks, Recreation and Historic Preservation (OPRHP) will result in changes to the length of the on-land cable route. Landfall at the Fishing Piers will result in an additional 3 miles of upland cable burial from the Fishing Pier to the southern terminus of the Wantagh State Parkway. Location of the facilities at the Duffy Avenue Converter Station site will result in an additional 1.7 miles of upland cable route between the Newbridge Road Substation and the Duffy Avenue site. DC cable would be installed underground using a combination of cut-and-cover, pipe jacking and directional drilling methods from the landfall exit point, at the Fishing Piers, to the converter station site at 508 Duffy Avenue, a distance of approximately 12.2 mile. The majority of the upland DC cable would be buried 4 feet deep in an open trench in a minimum 24-inch fill

1 The first supplement to the Neptune RTS Article VII application was submitted February 2003. In that supplement impacts associated with locating the converter station at the Nassau County Cedar Creek Wastewater Treatment Facility were evaluated. That location is no longer under consideration.

layer with appropriate thermal characteristics and then covered with a pre-cast concrete slab. The remainder of the trench would be backfilled with native soil that was removed during the trenching procedures. Directional drilling will be used to install the DC cable under tidal wetlands at the landfall and at three channel crossings along the Jones Beach Causeway. Directional drilling or pipe jacking will also be used at road and rail crossings where necessary along the route. More detailed descriptions of the DC cable and underground construction are included Exhibits E-l and E-3. A DC-AC converter station would be constructed on an approximately 18 acre parcel at 508 Duffy Avenue (see revised Figure 2-3). A more detailed description of the existing conditions at the site is included in Exhibit 4.2. A more detailed description of the proposed converter station is included in Supplemental Exhibit E-2. AC cable would be installed underground using cut-and-cover and directional drilling methods from the Duffy Avenue Converter Station site to the Newbridge Road Substation, a distance of approximately 1.7 miles. The AC cable would be installed parallel to the DC cable, in a separate trench, with a minimum separation of 15 feet between the cables. The upland construction would be the same as described for the DC cable. More detailed descriptions of the AC cable and underground construction are included in Supplemental Exhibits E-l and E-3.

Environmental Impacts Routes, installation techniques, construction/installation scheduling, and technology have been selected to avoid or minimize potential adverse environmental impacts resulting from installation and operation of this project. To minimize impacts to land use and to natural resources on Long Island, the route has been sited within the existing Jones Beach Causeway and Wantagh State Parkway ROWs. Directional drilling techniques will be employed to avoid impacts to tidal wetlands at landfall and at three channel crossings along the Jones Beach Causeway. Directional drilling will be used to avoid impacts to NYSDEC Freshwater Wetland F-3. The remainder of the upland route along the Causeway will be installed using conventional cut-and-cover techniques with appropriate erosion and sedimentation control measures, such as silt fencing, in place. The Duffy Avenue Converter Station has been sited within an area dominated by industrial and

The station's exterior design will incorporate suggestions from the local residents and planning officials and will incorporate features consistent with existing structures in the area. To mitigate temporary installation impacts on the bike path Neptune RTS• will work with user groups, OPRHP and Nassau County to reroute where possible and to develop permanent improvements to the bike path. The converter station will be designed to minimize noise and visual impacts.

4.2 Project Settings 4.2.2 Long island Project Location

Landfall to the Southern Terminus of the Wantagh State Parkway Landfall at the Fishing Pier requires approximately 3 miles of additional upland construction between the Fishing Pier and the originally proposed landfall at the southern terminus of the Wantagh State Parkway and a corresponding reduction in in-water installation in Hempstead Bay. The new upland cable route will be along the east side of the Jones Beach Causeway, which crosses Green Island, Low Island, Great Island and Sloop Channel, Goose Creek and Island Creek to connect Jones Beach to the Mainland. Landfall will be made using horizontal directional drilling technology from a point along the east side of the Jones Beach Causeway. The work area for the directional drill is an open, mown area, parallel to the roadway, with no shrub or tree growth. A maintained area and bike path are located along the east side of the Causeway from the landfall point to the mainland. The area east of the bike path is not maintained and contains dense shrub and herbaceous growth with scattered trees. Construction will proceed along the east side of the Jones Beach Causeway within the maintained area and under the bike path to the greatest extent possible, and will be ac- complished utilizing cut and cover methods. In some areas clearing of shrub growth may be required east of the bike path to avoid existing utilities along the Causeway. Interested agencies will be consulted with regard to the location and extent of clearing and all areas to be cleared will be identified in the EM&CP. Directional drilling will be utilized for channel crossings at Sloop Channel, Goose Creek and Island Creek. Work spaces for directional drilling will be located within open areas with no shrub growth to the greatest extent possible, and interested agencies will be consulted with regard to the location and extent of areas to be cleared.

Duffy Avenue Converter Station The Duffy Avenue Converter Station site is located at 508 Duffy Avenue in the Town of North Hempstead, County of Nassau, Long Island, New York (see revised Figure 2-3). The project site (the "site") is part of a larger parcel owned by OPRHP. The site is bounded on the north by the Long Island Railroad, on the east by existing industrial development, on the south by

02:0Oi412_EA01_07_02-B1132 4.2-1 EXHIBIT_4.2Duffy.doc-06/27/03 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Exhibit 4 Supplement - Environmental Impact

Duffy Avenue, and on the west by Wantagh State Parkway. The parcel is located within an industrial/commercial section of the Town of North Hempstead. The southern portion of the Duffy Avenue site is currently used by the New York State Department of Transportation (DOT) for the storage of equipment, salt, and sand. The storage facility includes an asphalt driveway and parking lot, a one-story garage, a salt storage shed and a gravel yard with piles of sand and soil. A DOT landfill, capped in 1995 and used solely for the storage of non-putrescible highway waste, is located in the north-central portion of the site. The landfill area will not be impacted by the converter station footprint. A maintained field occupies the northeast portion of the site, piles of road debris and culvert pipe occupy the northwestern portion of the site and a wooded area acts as a buffer between the site and Wantagh State Park- way. The area within one mile of the Duffy Avenue site (the Study Area) includes institutions (e.g., schools), the Wantagh State Parkway, residential areas, commercial/industrial uses, and parks. The Study Area contains a substantial amount of commercial/industrial enterprises and a significant amount of suburban and residential dwellings. Commercial/industrial land uses are generally located along Prospect Avenue, Old Country Road, Duffy Road, and within a heavily industrialized area bounded by Old Country Road, Wantagh State Parkway, Long Island Railroad tracks and Grand Boulevard. Generally, adjacent neighborhoods include moderate density, single family homes and streets lined with concrete curbs, sidewalks, and street trees. Topography in the Study Area tends to be flat with few water features (i.e., rivers, ponds). The nearest residential land uses are northwest of the facility along the western side of the Wantagh State Parkway and are separated from the site by the Parkway, the Long Island Rail- road, existing commercial development and forested buffer areas along each side of the Parkway.

Additional Wantagh Parkway Cable Route Location of the converter station at Duffy Avenue will require installation of an additional 1.7 miles of additional cable route, along the east side of the Wantagh State Parkway, within the Parkway right-of-way between Newbridge Road and the Duffy Avenue Converter Sta- tion. In addition to the HVDC cable, AC cable will be buried within this additional cable corridor connecting the converter station to the Newbridge Road substation. HVDC and AC cables

An expansive maintained area that includes the continuation of the bike path exists along the east side of the Parkway in this area. Scattered groupings of mature trees are located within the maintained area. The parallel cables would be installed using a combination of horizontal directional drilling and cut-and-cover techniques. Directional drilling will be used where necessary to avoid impacts at highway crossings. The remaining portions of the cable would be installed by traditional cut-and-cover techniques. Adequate space for directional drill work space and the parallel cable trenches exists within open areas in most areas. Some clearing of shrubs may be required near mature tree groupings in order to accommodate both cables, but no tree removal is anticipated. The design and construction of the converter station and cable are described in detail in Exhibits E-l, E-2, and E-3. Exhibit 4.12 includes visual simulations of the Duffy Avenue Con- verter Station.

4.3 Topography, Geology, Soils, and Groundwater 4.3.2 Long Island Project Location The topography, geology, and groundwater conditions at the Duffy Avenue Converter Station location and at the associated AC and DC cable connections are generally the same as presented in the Application in connection with the Wantagh State Parkway and the Newbridge Road Substation. The conditions and impacts associated with the project that have changed are discussed below.

4.3.2.1 Existing Conditions

Landfall to the Southern Terminus of the Wantagh State Parkway The route along the Jones Beach Causeway from the landfall to the southern terminus of the Wantagh State Parkway crosses a series of islands separated by channels. The topography on the islands is relatively flat as described for mainland portions of the project in the Application. The geology along the Jones Beach Causeway is similar to that described in the Application for the Wantagh State Parkway. The Soil Conservation Service Soil Survey of Nassau County, New York was reviewed to determine soil types, other than those presented in the Application, that may be present along the Causeway portion of the route. All soils from the landfall to the southern terminus of the Wantagh State Parkway are mapped as Udipsamments, wet substratum (Ue). Areas mapped as Udipsamments, wet substratum are nearly level low areas that have been filled with sandy material typically dredged from nearby waterways. Fill is typically 3.5 to 8 feet deep and underlain by organic tidal marsh sediments. These are very deep, moderately well or well drained soils, with slopes from 0 to 3%. Permeability is rapid in the sandy layers and moderate in the underlying organic layers. The water table is found at depths of 3.5 feet or more and is often tidally influenced. It is expected that groundwater will be encountered along the cable route south of Sunrise Highway. Groundwater in this area may be subject to tidal influence.

Duffy Avenue Converter Station The Duffy Avenue Converter Station is located along the east side of the Wantagh State Parkway north of Duffy Avenue and south of the Long Island Railroad in the Town of North Hempstead. Construction of the converter station at this location would not impact the topography, since the area proposed for development has been previously developed and is relatively flat. The site does not exhibit major topographic relief and is currently used by NYSDOT as a storage area for salt, sand, and equipment. The geology at the Duffy Avenue Converter Station is similar to the Newbridge Substation discussed in the original Application. The Soil Conservation Service Soil Survey of Nassau County, New York was reviewed to determine soil types, other than those presented in the Application, that may be present at the Duffy Avenue Converter Station site. Soil units mapped at the site include Hempstead silt loam (He), urban land (Um & Ug) and sand and gravel pits (Pk). A sand and gravel pit is depicted in the north portion of the site, Hempstead silt loam is depicted along the western portion of the site and urban land is depicted in the remaining portions of the site. Figure 4.3-1 presents the project site outline on a copy of sheet number 8 of the Nassau County soils map. Descriptions of each soil mapping unit are described below. Hempstead soil is very deep, well drained soils on outwash plains, with slopes from 0 to 3%, that formed in a loamy mantle overlying stratified sand and gravel. Permeability is moderate from the surface to the upper part of the subsoil and rapid in the lower subsoil and substratum. The water table below this soil is found at depths of more than 6 feet. Hempstead soil is moderately to very strongly acid. A forested buffer between the area proposed for development and the Wantagh State Parkway currently exists in the area mapped as Hempstead silt loam. Underground cables will cross this soil type. In areas mapped as Urban land (Ug) 85% or more of the surface is covered with manmade impervious building materials such as asphalt or concrete. Areas mapped as Urban land- Mineola complex (Um) include about 75% urbanized areas (buildings, roads, driveways, parking lots and other manmade structures), 20% Mineola soils and 5% other soils. The complex consists of very deep, moderately well drained soils in urbanized areas, with slopes from 0 to 3%. Permeability of the Mineola soils in the complex is moderately rapid from the

02:0014I2_EA01_07_02-B1132 4.3-2 Exhibit 4.3Duffy.doc-06/27/03 Neptune Regional Transmission System LLC Article VU Application Second Supplement June 2003 Exhibit 4 Supplement - Environmental Impact

surface through the subsoil and very rapid in the substratum. The water table below Mineola soil is found at depths of 2 to 4 feet during seasonally wet periods. Mineola soil is moderately to very strongly acid. Converter station development is proposed in areas underlain by Urban land. Areas mapped as sand and gravel pits (Pk) have been used for the excavation and removal of sand and gravel. The gravel pit depicted on the soil survey map was subsequently used as a landfill for highway debris and was capped in 1995. No development is proposed in this area. Based on historical uses of the site there is no reason to suspect that soils at the site are contaminated. Regional groundwater conditions at the Duffy Avenue Converter Station are similar to those at the Newbridge Road Substation, discussed in the original Application. Local conditions are better understood as a result of groundwater studies that have been conducted in the area in association with DEC directed remedial investigations at several sites in the area. The depth to groundwater is about 65-70 feet below the surface. The direction of groundwater flow is to the south-southwest. A volatile organic contaminant (VOC) plume originating at the General Instruments site 1/4 to 1/2 mile to the northeast of the site has been detected approximately 180 feet below the surface at the proposed converter station site. There is no evidence that any contamination from the Duffy Avenue converter station site has contributed to this plume. The contaminant plume sinks as it moves away from the General Instruments site past the Duffy Avenue site. As part of an Interim Remedial measure (IRM) developed to address the General Instruments plume a groundwater recirculation technology has been installed. The technology involves extracting the contaminated groundwater, "stripping" the VOCs from the water and reinjecting the cleaned water. The water then recirculates back through the ground and a portion of it is retreated. One "stripping" system has been installed at the Duffy Avenue site and another is scheduled to be installed in September 2003. Discussions are in progress to ensure that the operation of these systems will not be impacted by the construction or operation of the converter station.

Additional Wantagh Parkway Cable Route The topography, geology soils and groundwater for portions of the project between Newbridge Road and the Duffy Avenue Converter Station site are the same as those described in the Application for other portions of the Wantagh State Parkway ROW.

4.3.2.2 Potential Impacts and Mitigation

Landfall to the Southern Terminus of the Wantagh State Parkway The project will have no permanent impact on topography, geology, soils, and groundwater for portions of the project between landfall and the southern terminus of the Wantagh State Parkway. Impacts to topography and geology are the same as those discussed in the Application for portions of the project within the Wantagh State Parkway ROW. Soils to be impacted are fill areas and will be restored to existing condition once construction is complete. Therefore impacts will be temporary during construction. It is expected that groundwater will be encountered along the cable route south of Sunrise Highway and groundwater in this area may be subject to tidal influence. A Long Island Well Permit is required for any discharge of groundwater at rate equal to or greater than 45 gallons per minute. Discharges at this rate are not expected. However, should a need for dewatering at this rate arise, Neptune will consult with DEC and DPS to determine appropriate dewatering procedures to avoid impacts to groundwater. Dewatering procedures will be included in the EM&CP. Horizontal directional drilling will be used for channel crossings along this portion of the route. Impacts associated with the horizontal directional drilling (HDD) process also are not significant, since appropriate dewatering practices will be employed to avoid any impact on groundwater quality. In addition, impacts from the use of drilling fluids are not expected because 1) the fluids used are not hazardous materials, 2) they will be reused, and 3) techniques will be employed by the drilling subcontractor to avoid surface return of drilling fluids during installation. A more detailed description of installation techniques is included in Exhibit E-3. More detail with regard to control of drilling fluids and minimization of impacts associated directional drilling has been provided in response to Discovery Request DEC-22.

Duffy Avenue Converter Station Operation of the converter station at the Duffy Avenue site will not impact topography, geology, soils, or groundwater. Impacts to topography and geology will be avoided as discussed in the Application for the Newbridge Road Substation. The converter station will be constructed on portions of the site that are underlain by urban soils that have been previously disturbed. Therefore the project will have no impact on soils. The converter station will be constructed south of the landfill to avoid impacts to the landfill. Therefore the construction and operation of the converter station will not have any impact on the landfill. No impacts to groundwater are anticipated in connection with construction or operation of the converter station. It is anticipated that the foundation of the converter station will be a concrete slab. However, the feasibility of this approach is dependant on geotechnical borings. If pilings are required they would not be deeper than 15 to 20 feet. No impacts at depths of 180 feet below the surface, where groundwater contamination would be encountered, are anticipated in connection with construction of the project. Neptune will continue to work with DEC to ensure that groundwater is not impacted by the project. Final design of the converter station foundation will be included in the site plan in the EM&CP.

Additional Wantagh Parkway Cable Route The project will have no impact on topography, geology, soils and groundwater for portions of the project between Newbridge Road and the Duffy Avenue Converter Station site, as discussed in the Application for portions of the project within the Wantagh State Parkway ROW.

4.7 Freshwater and Tidal Wetland Resources 4.7.2 Long Island Tidal wetlands, under state and federal jurisdiction, located along the Jones Beach Cause- way between the Fishing Pier landfall and the southern terminus of the Wantagh State Parkway will not be impacted by construction. Neither the Duffy Avenue Converter Station site nor the cable route between Newbridge Road and the Duffy Avenue site contain any New York State or federally jurisdictional wetlands.

4.7.2.1 Existing Conditions Available map resources were used to determine whether tidal or freshwater wetlands and floodplains were present at the converter station site or along the cable route. A site reconnais- sance was conducted on April 3, 2003, to confirm site conditions and identify any additional wetland resources.

A 300-foot buffer line has been added to the route to illustrate which wetlands are within 300 feet of the proposed route. FEMA Flood Insurance Rate Maps were reviewed to determine the location of the 100- year floodplain in the vicinity of the upland cable route between the Fishing Pier landfall and the southern terminus of the Wantagh State Parkway. The floodplain maps (see revised Fig- ure 4.7-4) show that this portion of the upland cable route is within areas mapped as Zone VE, Zone AE and Zone X500. Zone VE is defined as an area inside the 100-year floodplain with a velocity hazard. Zone AE is defined as an area inside the 100-year floodplain with no base flood elevation. Zone X500 is defined as an area outside the 100-year floodplain but inside the 500-year floodplain.

Duffy Avenue Converter Station Wetland maps, showing wetlands under state or federal jurisdiction, depict no wetlands at the Duffy Avenue Converter Station site. A site visit on April 3, 2003 confirmed that there are no wetlands at the site. 'y FEMA Flood Insurance Rate Maps were reviewed to determine the location of the 100-year floodplain in the vicinity of the Duffy Road Converter Station site. The floodplain maps (see revised Figure 4.7-4) show that the site is within an area mapped as Zone X. Zone X is defined as an area outside the 100-year and 500-year floodplains.

Additional Wantagh Parkway Cable Route The additional upland cable extends approximately 1.7 miles, within the Wantagh State Parkway ROW, between Newbridge Road and the Duffy Avenue Converter Station site. The route is confined to the extensive maintained area along the east side of the parkway. No wetlands, under state or federal jurisdiction, are depicted along this portion of the route.

4.7.2.2 Potential Impacts and Mitigation

Landfall to the Southern Terminus of the Wantagh State Parkway Installation will require three channel crossings along the Jones Beach Causeway. Hori- zontal directional drilling techniques will be utilized to avoid impacts to the channels and associated tidal wetland habitats. Construction in upland areas will occur along the east side of the Jones Beach Causeway, within the maintained right-of-way and the existing bike path to the greatest extent possible. The majority of this portion of the route is within the 300 foot buffer regulated by NYS adjacent to tidal wetlands. Some removal of shrub growth may be required to offset the project from existing underground facilities along the route. Interested agencies will be consulted with regard to the location and extent of clearing and all areas to be cleared will be specified in the EM&CP. Cut and cover construction techniques will be used to install the cable within the upland areas along the Causeway, with appropriate erosion and sediment controls used to avoid impacts to tidal wetlands. While the route traverses areas within the 100 and 500 year floodplains, the route will be restored to pre-construction contours. Therefore, no impacts to floodplains will occur.

Duffy Avenue Converter Station Construction and operation of the Duffy Road Converter Station and cable route will not affect wetlands. No wetlands, under state or federal jurisdiction, exist within the Duffy Road Converter Station site. The Duffy Avenue Converter Station site is located outside the 100-year and 500-year floodplains. No impacts to floodplains will occur as a result of construction at the site.

Additional Wantagh Parkway Cable Route No wetlands, under state or federal jurisdiction, exist within the project area between Newbridge Road and the Duffy Avenue Converter Station site. Therefore, no wetlands will be

4.8 Wildlife and Protected Species, Terrestrial Route 4.8.2 Long Island 4.8.2.1 Existing Conditions

Landfall to the Southern Terminus of the Wantagh State Parkway Permit The cable will make landfall at a point near the Jones Beach State Park Fishing Pier and then proceed north within the right-of-way (ROW) along the east side of the Jones Beach Causeway to the southern terminus of the Wantagh State Parkway. The route will require three channel crossings and installation with the maintained area and bike path adjacent to the parkway. Large congregations of terns, gulls, waders, and shorebirds nest in Hempstead Bay and the adjacent beach, marsh, and island habitats. Piping plovers, least terns, common terns, and black skimmers nest in the sandy areas adjacent to the bay, while a variety of species of wading birds (e.g., herons, egrets) utilize shrubby patches for nesting. The area is an important site for heron nesting, and it provides breeding habitat for all species of wading birds in the state (Bull 1998). Also, several of the islands within the Hempstead Bay complex support breeding colonies of protected birds (i.e., black skimmer, least tern, common tern). Endangered roseate terns are also believed to nest in portions of Jones Beach State Park. Peregrine falcons, a species formerly listed by the USFWS and presently listed as endangered by New York State, is reported to inhabit this region as well. Falcons likely prey on the area's abundant avifauna, such as ducks and other common birds (USAGE 1999). Hempstead Bay is also an important component of the Atlantic Flyway for migrating birds and over-wintering waterfowl (ducks and geese).

Duffy Avenue Converter Station The Duffy Avenue Converter Station would be constructed on a parcel of land along the east side of the Wantagh State Parkway, within an area heavily developed for industrial and commercial use. A description of the converter station site is presented in Exhibit 4.2. A one- story structure used as a garage by DOT occupies the southern portion of the parcel. A DOT landfill, capped in 1995, is located in the north-central portion of the site. A wooded area acts as a buffer between the site and Wantagh Parkway. There are no wetlands at the project site.

Consultation with the US Fish and Wildlife Service and the New York Natural Heritage Program found no known occurrences of rare or state/ federal-listed plants, animals, significant natural communities or other significant habitats in the vicinity of the converter station site. Copies of the agency correspondence are attached to this section. Wildlife use within the alternate project area is expected to be limited to species adapted to urban settings as discussed in previous submissions.

Additional Wantagh Parkway Cable Route The additional cable route extends approximately 1.7 miles between the Duffy Avenue Converter Station and the Newbridge Road Substation. The route is confined to the maintained area adjacent to the parkway. There are no wetlands along this portion of the route.

4.8.2.2 Impacts and Mitigation

Landfall to the Southern Terminus of the Wantagh State Parkway Construction in the Hempstead Bay area will take place in upland areas along the east side of the Wantagh Causeway, within the maintained right-of-way and the existing bike path, in the late fall and early winter. While several areas within Hempstead Bay may be utilized by threatened and endangered avian species for nesting, the maintained area along the causeway and the paved bike path do not offer suitable nesting habitat. Construction occurring during the fall and winter will avoid nesting periods for these species within Hempstead Bay. Channel crossings will utilize horizontal directional drilling technology to avoid impacts to wetlands and other sensitive habitats as well as the species that utilize these habitats. Therefore no impacts to threatened and endangered species or nesting habitat are expected. The proposed timing of cable installation activities and construction mitigation measures as recommended by USFWS, NYSDEC, and NYSNHP will avoid impacts on protected species and habitat.

Duffy Avenue Converter Station Potential impacts on wildlife at the Duffy Road Converter Station site are expected to be minimal and limited to common species adapted to urban settings.

Re: Neptune Project

Dear Ms. Pietrusiak:

The Neptune Regional Transmission System is a project of Atlantic Energy Partners. Phase I of this 4-phase project is intended to connect electric load centers in New Jersey to substations in New York City and on Long Island. The system will use direct current technology and AC-DC current to overcome constraints to the existing land-based electric transmission grid. We previously requested information for this project in November 2001. We are currently looking at two alternative sites for the converter station in Westbury, NY. One site is located at 1100 Prospect Ave and the other is located directly south on Duffy Road. We are also siting a transmission line that would run parallel to Wantagh Parkway, from Newbridge Road to the Prospect Ave site.

We are requesting information regarding the presence of endangered or threatened plant and animal species, species of special concern and the existence of critical or significant habitats on or within 1.5 miles of the two potential converter sites identified on the attached maps and the transmission line paralleling the parkway. This information is being requested in order to facilitate site selection and completion of permit and licensing applications for submission to New York and federal regulatory agencies.

The enclosed map depicts the locations under consideration for the proposed converter station. Thank you for your consideration in this matter. Please send your response to me at Ecology & Environment, Inc., 368 Pleasant View Drive, Buffalo, New York 14086.

Dear Mr. McCarthy:

In response to your recent request, we have reviewed the New York Natural Heritage Program databases with respect to the proposed Neptune Converter Station Project - 2 alternative sites, as indicated on the map you provided, located in the Town of Westbury, Nassau County.

We have no records of known occurrences of rare or state-listed animals or plants, significant natural communities, or other significant habitats, on or in the immediate vicinity of your site.

The absence of data does not necessarily mean that rare or state-listed species, natural communities or other significant habitats do not exist oh or adjacent to the proposed site. Rather, our files currently do not contain any information which indicates their presence. For most sites, comprehensive field surveys have not been conducted. For these reasons, we cannot provide a definitive statement on the presence or absence of rare or state-listed species, or of significant natural communities. This information should not be substituted for on-site surveys that may be required for environmental assessment. Our databases are continually growing as records are added and updated. If this proposed project is still under development one year from now, we recommend that you contact us again so that we may update this response with the most current information. This response applies only to known occurrences of rare or state-listed animals and plants, significant natural communities and other significant habitats maintained in the Natural Heritage Databases. Your project may require additional review or permits; for information regarding other permits that may be required under state law for regulated areas or activities (e.g., regulated wetlands), please contact the appropriate NYS DEC Regional Office, Division of Environmental Permits, at the enclosed address.

4.10 Land Use

Methodology A qualitative land-use assessment was conducted to evaluate the compatibility of the Duffy Avenue Converter Station site in the Town of North Hempstead with existing and future land uses and local and state land-use plans. Thaassessment was conducted considering the building code of the Town of North Hempstead and the Nassau County Comprehensive Master Plan.

4.10.2 Land Use - Long Island This section describes land use, zoning, and public policy designations for the Duffy Avenue Converter Station site.

4.10.2.1 Existing and Proposed Land Use The Duffy Avenue Converter Station site is bounded on the north by the Long Island Railroad, on the east by existing industrial development, on the south by existing DOT storage facilities, and on the west by Wantagh Parkway. The majority of the site is currently, cleared and undeveloped. A DOT landfill, capped in 1995, is located in the north-central portion of the site. The landfill was used solely for the storage of non-putrescible highway waste. A wooded area acts as a buffer between the site and Wantagh Parkway. The Duffy Road site is owned by the New York State Office of Parks, Recreation and Historic Preservation and would be leased to the applicant. It is currently used by the New York State Department of Transportation. The site is a portion of a larger parcel. A one- story structure used as a garage by DOT occupies the southern portion of the parcel. A treatment unit design to treat contaminated groundwater about 180 feet below the surface is also located on the site. The source of the contamination is the General Instruments site that is located 1/4 to 1/2 mile to the north east of the converter station site. A succesor corporation to General Instruments maintains the unit under DEC's direction. An additional treatment unit may be placed on the site in September 2003. Based on preliminary discussions with DEC it does not appear that the converter station will interfere with the treatment program.

4.10.2.2 Zoning The property is unzoned because it is owned by the State of New York. It is however located in an area that is primarily used for commercial and industrial purposes. See Figure 4.10. As discussed more fully in Exhibit 7 for the purpose of this application the site is being assessed as though it were zoned Industrial B, consistent with its current use and its surround- ings. The converter station will be in compliance with all applicable code requirements except building height and parking capacity. See Exhibit 7.

4.10.2.3 Consistency with Local Land Use Land use in the vicinity of the proposed Converter Station includes institutions (e.g. schools), the Wantagh State Parkway, residential areas, commercial/industrial uses, and parks. In addition to a significant amount of suburban residential dwellings, the area contains a substantial amount of commercial/industrial enterprises. Generally, adjacent neighborhoods include moderate density, single family homes and streets lined with concrete curbs, sidewalks, and street trees. Commercial/industrial land uses are generally located along Prospect Avenue, Old Country Road, Duffy Road, and within a heavily industrialized area bounded by Old Country Road, Wan- tagh State Parkway, the Long Island Railroad tracks and Grand Boulevard. . A Visual Impact Assessment was performed to determine the potential visual impact of the proposed converter station. That assessment which is included in Exhibit 4.12 of this supplement concluded the converter station will not significantly change the existing visual/aesthetic character of the area. The facility will 1) conform to design guidelines utilized by the local municipality, 2) utilize materials and colors that minimize contrast with existing facilities/landscape features, 3) limit removal of existing vegetation, and 4) include landscape plantings around the converter station periphery to maximize screening from adjacent viewers. The proposed converter station is consistent with commercial and industrial land uses immediately surrounding the site and will not be visible from most other land uses in the area. The facility will be designed to be consistent with the local noise code and with public health and safety. No air emissions or odors will be generated by the facility. Therefore, the project is compatible with surrounding land uses.

Nassau County Master Plan The Nassau County Comprehensive Master Plan is a statement of community goals and policies concerning the development, protection, and revitalization of the county as a whole, and it forms the basis of the town ordinances in Nassau County that regulate land-use development through zoning and other regulations. The Master Plan includes several observations, opportunities, and goals that are consistent with development of the Duffy Avenue Converter Station. Among these are findings that the population of Nassau County will increase over the next several years, that the current housing stock is old and not compatible with the current population demographics, and that degradation of air quality is a primary concern. The Converter Station is consistent with these observations, opportunities, and goals as presented in the Master Plan. The Neptune RTS• facility will provide additional energy resources for the area to serve the growing population and the expected increase in housing inventory. The Project would bring energy to the area without the concomitant air emissions associated with a traditional power plant. The location of the converter station in an industrialized area will enhance development patterns by containing utility structures within the same area. Once in operation, the converter station would generate no commuter traffic and very little delivery traffic, typically only a few vehicles a week.

4.11 Archaeological and Historic Resources This section describes the potential archaeological and historic resources in the vicinity of the Jones Beach Causeway, the Duffy Avenue Converter Station and the upland cable route between Newbridge Road and the Duffy Avenue Converter Station.

4.11.2 Long Island Modifications to the original Application presented in this Second Supplement include: changing the landfall location to the vicinity of the Fishing Piers and the associated addition of approximately 3 miles of upland cable installation; changing the location of the converter station; and the addition of approximately 1.7 miles of upland cable installation between Newbridge Road and the Duffy Avenue Converter Station (see revised Figure 2-3).

Landfall to the Southern Terminus of the Wantagh State Parkway The DC cable will make landfall at a point near the Jones Beach State Park Fishing Pier and then proceed north within the right-of-way (ROW) along the east side of the Jones Beach Causeway to the southern terminus of the Wantagh State Parkway, rather than at the southern terminus of the Wantagh State Parkway, as originally proposed. Construction will take place in upland areas along the east side of the Causeway, within the maintained right-of-way and the bike path to the greatest extent possible. There are three water crossings along the causeway: Sloop Channel, Goose Creek and Island Creek. The cable will be installed in bore holes created via horizontal directional drilling at each of these crossings.

Duffy Avenue Converter Station The converter station will be constructed on a leased parcel located along the east side of the Wantagh State Parkway north of Duffy Avenue and South of the Long Island Railroad. The parcel is located at 508 Duffy Avenue and is owned by the New York State Office of Parks, Rec- reation and Historic Preservation.

Wantagh State Parkway ROW A discussion of the cultural and archaeological resources along the Wantagh State Park- way ROW and the potential impacts of the project on those resources is presented in Section 4.11 of the Application. Figure 2-3 shows general locations of potentially historic properties also discussed in the Application. On February 13,2002, the OPRHP determined that installation of the proposed cable along the Wantagh State Parkway ROW would not adversely impact any significant cultural resources (see attached letter). This determination applies to the ROW between the southern terminus of the Wantagh State Parkway and the Newbridge Road Substation. The remainder of this section addresses those new parts of the route not previously evaluated by OPRHP.

Landfall to the Southern Terminus of the Wantagh State Parkway Landfall will occur near the Fishing Pier and the cable will continue due north on the east side of the Jones Beach Causeway to the southern terminus of the Wantagh State Parkway. This landfall and the proposed cable route are located within an area that contains several historic structures that are recorded on OPRHP inventories and are NRHP-eligible (see Table 4.11-2[R]] Installation of the proposed cable will not involve demolition, alteration or impact to any of these historic structures.

Duffy Avenue Converter Station The converter station site is bounded on the north by the Long Island Railroad, on the east by existing industrial development, on the south by Duffy Avenue, and on the west by Wantagh State Parkway. A DOT landfill, capped in 1995, is located in the north-central portion of the site and an existing DOT storage facility occupies the southern portion of the site. The landfill was used solely for the storage of non putrescible highway waste and the converter station development will avoid the landfill area. The landfill is in an area of the site used for the excavation and removal of sand and gravel (see discussion of soil in Exhibit 4.3 for additional information). The site contains piles of sand, soil and road debris such as brush, auto parts, and litter. A wooded area acts as a buffer between the site and the Wantagh State Parkway. There are no known cultural resources at the proposed converter station site. Information on archaeological and historical resources associated with the Duffy Avenue site was collected for a 3-mile-radius study area. The results of this study are summarized in Ta- ble 4.11-2 (R).

Additional Wantagh Parkway Cable Route HVDC and AC cables would be installed in separate parallel trenches for the 1.7 mile portion of the route along the Wantagh ROW north of the Newbridge Road substation to the proposed Duffy Avenue converter station. These trenches will follow the roadbed of the Parkway, in a setting similar to that, which has been reviewed and cleared by SHPO on February 12, 2002.

4.11.2.2 Potential Impacts and Mitigation No potential impacts to cultural resources have been identified along the newly proposed route. Information on the route from the Fishing Pier to the southern terminus of the Wantagh State Parkway, the Duffy Avenue converter station site and the Newbridge Road to Duffy Avenue cable routes has been submitted to the OPRHP for consultation under Section 14.09 of the State Historic Preservation Act. No formal response has been received as of the submission of this supplement. Any concems identified by OPRHP will be addressed either by modification of the route or mitigative measures.

Dear Ms. Deixler:

Re: PSC Case #02-T-0036 Neptune Regional Transmission System Sayerville, NJ to West 49* St., Manhattan and to Newbridge Rd., Town of Hempstead Article VII filing 02PR0422

Thank you for requesting the comments of the Office of Parks, Recreation and Hfeterir Presen.at.on (OPRHP) with regard to the potential for this pr^ to affi iSt h.stoncal/cuttural resources. OPRHP has received a copy of the Vplfcab?n oflerStefo Environmental Compatibility and Public Need " dated January 2002. We wHI be revSo this project in accordance with Section 14.09 of the State Historic Presetvation AS of 19?^

After reviewing this document ORPHP offers the following comments:

1. OPRHP concurs that the terrestrial portions of the proposed line within New York will 2 ,n areaS that haVe Subje<:t to substan ^ JS ^ h ^ ^ Prior SstuSanS Sns of STe pSL?0 COnCernS re9ardin9 archaeo,09k:al ^ on the terrestrial

OPRHP also concurs with the recommendation for remote sensing surveys of all submerged sections of the project that fall within the boundaries of New York State However, while the application indicates that this survey will be conducted to search SdS ^ Shipwrecks) 0PRHP has other ^ncems that will^ed^te

During the Pleistocene, accumulation of ice and the development of glaciers resulted m s.gmficant drops in sea level and the exposure of extensive surfac^ tSat ha?S S^^6^- ^the PleiSt0Cene ended and ^ 9|aa^ melted ^ev^er returned to the seas once again inundating these surfeces. The earliest occupation of the western hem.sphere (including New York) occurred during the period Avhen tiiese surfaces were exposed and many of them were utilized by the earliest Americans Intact archaeological sites have been identified in some of these now submerged areas and there are several areas within this project corridor that have a high potential for such sites. Therefore, OPRHP recommends that investigation of the submerged portions of this project include an evaluation of the potential for these types of surfaces to be present and intact and a consideration of the potential for the presence of archaeological sites on such intact surfaces

Re: Neptune Regional Transmission System Project, 02PR0422. Underwater Prehistoric and Historic Archaeological Study, Lower Raritan River, New Jersey to Fishermen Cove, Seaford New York.

Dear Mr. Mackey: Neptune Redonal Transmission System, LLC ("NeptuneRTS•" or "Applicant") has applied for a^U S. Army Corps of Engineers permit under Section 10 of the Rivers and Harbors Act of 1899 and Section 404 of the Clean Water Act and a Certificate of Environmental Compatibility and Public Need under Article VE of the New York State Public Service Law to connect the electric transmission systems m Long Island and New Jersey through the installation of an approximately 7-inch 600-MW (500 kV) high- voltage direct-current (HVDC) submarine electrical transmission cable. The cable route will extend from the converter site located near First Energy's Rantan Substation in Sayreville New Jersey to a converter site located in the hamlet of New Cassel, Town of North Hempstead, Long Island. The project schedule calls for manne cable construction/installation activities to begin in the fall of 2005 and the system to be energized in the spring of 2006.

Consultation with ORPH on this project was initiated in January 2002. At that time the project proposed two distinct cable routes. One route went from Sayreville to Manhattan. The other was the currently proposed Sayreville to Long Island route. The Sayreville to Manhattan route is no longer under consideration.

On February 13, 2002, the OPRHP determined that installation of the proposed cable alon^ the Wantagh State Parkwav ROW in Long Island would not adversely impact any significant cultural resources. The Long Island upland route has since been modified and consultation regarding the route change is ongoing.

On December 13, 2002, your office sent to us a letter requesting that an underwater remote sensing survey be comoleied for the marine portion of the project. The OPRHP letter also stated that the underwater study should address the potential for submerged prehistoric site in the project corridor. In response to that letter Ecology and Environment, Inc., (E & E) contracted the WCRM, Inc., an underwater archaeology

crooi-u: EAOIJWJ.'O-BII'JS 1. M:ickovJ)6:OO.ViJoc-u/:0/;00? Mr. Douglas P. Mackey June 20, 2003

Pa2e2•'t;v consulting firm based on Bristol, Maine, to conduct the survey of the proposed DC line that will be installed in the Lower Raritan River, the Lower New York Bay, the Atlantic coastal waters off Long Island and Hempstead Bay. The survey was completed in October 2003 and the WCRM report is enclosed for your review and comment.

The survey utilized magnetometer, side scan sonar, subbottom profiler, bathymeter, and marine geotechnical cores. As the result of this investigation it was determined that the excavation of the trench accommodating the DC line will affect modem estuanne silts, but will have no effect on Pleistocene pre-transgressive surfaces that might have potential for prehistoric resources. The remote sensing survey identified 39 magnetic anomalies (targets) potentially representing historic shipwrecks within 200-meter wide survey corridor along the cable route Sixteen of those are in New York waters. WCRM, Inc., recommended direct visual inspection of these targets by certified divers, and the NRHP evaluation of any verified shipwrecks. Dr. Warren Riess, the WCRM Inc., marine archaeologist, also noted that due to the factors outside of his control, the magnetometer was flown at 11 meters or higher above the bottom along a 5.9 kilometer- long section of the route; this represents less than optimal surveying conditions. This relative data gap affects three out of seven tracklines of the survey corridor. Dr. Riess recommends that these tracklines be resurveyed.

Neptune requests the OPRHP conditionally approve the Corps and Article VH permit applications with the understanding that Neptune will complete the visual inspection and NRHP evaluations of the marine targets prior to commencement of construction. This progression will allow Neptune to secure construction financing, which is contingent of the issuance of permits, in the fall of 2003; complete the archeological studies and any required mitigation from the fall of 2003 to the summer of 2005; and initiate manne cable installation in the fall of 2005. If directed by the OPRHP, Neptune will enter into a programmatic agreement for this effort. If you have any questions or require additional information, please feel free to contact me at (716) 684-8060.

sincerely,^, .

4.12 Visual and Aesthetic Resources Environmental Design & Research, P.C. (EDR) conducted a visual and aesthetic analysis of the proposed Duffy Avenue Converter Station. A copy of the EDR report follows this section. The analysis was designed to determine the potential visual impact of the proposed converter station through:

• Viewshed analysis;

• Field evaluation;

• Computer-assisted visual simulation; and

• Line-of-sight cross section analysis.

A copy of the EDR report follows this section. The evaluation was based on design drawings provided by OEST Associates, Inc.

4.12.1 Existing Conditions The area within one mile of the proposed Duffy Avenue site includes institutions (e.g., schools), the Wantagh State Parkway, residential neighborhoods, commercial/industrial facilities, and parks. Dominant land use within the Study Area is suburban residential and commercial/industrial. Generally, adjacent neighborhoods include moderate density, single family homes and streets lined with concrete curbs, sidewalks, and mature street trees. Commercial/industrial land uses are generally located along Prospect Avenue, Old Country Road, and Duffy Avenue. Old Country Road, Wantagh State Parkway, the Long Island Railroad tracks and Grand Boulevard bound a heavily industrialized area. The commercial/industrial areas within the Study Area are generally characterized by an abundance of pavement and high to moderate density 1 to 2 story structures with flat roofs. Vegetation, including turf, within these areas is generally lacking. Topography in the Study Area tends to be flat with few visible water features (i.e., ponds). Based on review of existing data sources, the Study Area has no aesthetic resources of statewide significance, as defined by the New York State Department of Environmental Conservation (NYSDEC) program policy DEP-00-2 (NYSDEC, 2000). Within the Study Area, there are no State Parks, no state or federally designated trails, no Urban Cultural Parks, and no

The Wantagh State Parkway has also been determined to be eligible for listing on the State and National Register of Historic Places. These roads are the only aesthetic resources of statewide significance located within the Study Area. The Study Area also includes several areas that are considered visually sensitive due to their local significance or their intensity of land use. These sites are listed in Table 1. They include two parks/recreational facilities, one golf course, four public schools, several highly traveled roadways, and one residential neighborhood.

64 feet. The tallest transmission structure will reach approximately 88 feet above existing ground level.

4.12.2 Potential Impacts and Mitigation

The proposed converter station will not significantly change the existing visual/aesthetic character of the Study Area. While there will be a few open and partially open views of the facility, the overall visibility of the converter station will be limited. This is due to 1) the relatively flat topography within the study area, which results in few elevated viewpoints, 2) the effective screening provided by existing structures and/or vegetation in the surrounding area, and 3) the distance and screening (vegetation and built structures) that exists between the site and most of the sensitive resources/viewer locations within the Study Area. The proposed converter station will alter the visual character of certain foreground views. However, its scale, contrast and any perception of changed land use are minimized through 1) its location within an existing commercial/industrial area, 2) architectural treatments that are consistent with residential and commercial structures in the area, and 3) the commitment of the applicant to propose a final design that will blend in, as much as possible, with the existing structures/landscape in the area. Limited visual impact is also attributable to the fact that the site is not easily visible from Duffy Avenue, has limited sensitive receptors adjacent to the property and contains an existing structure that is comparable in height to the tallest proposed building. To minimize visual impact the final design of the proposed facility will 1) conform with any design guidelines utilized by the local municipality, 2) utilize materials and colors that minimize contrast with existing facilities/landscape features, 3) limit removal of existing vegetation, and 4) include landscape plantings around the converter station periphery to maximize screening from adjacent viewers.

Environmental Design & Research, P.C. (EDR) was retained by Ecology and Environment, Inc. (E&E) to undertake an analysis of the potential visibility and visual impact of the above-ground components of the proposed Neptune Regional Transmission System Project (Neptune Project). A Visual Impact Assessment (VIA) Report, and a supplement to that report, were previously prepared by EDR (EDR, 2002 A and 2002 B), and submitted to E&E for inclusion in its Article VII Application for the project. In January 2003, E&E requested that EDR complete a supplemental VIA for the proposed Duffy Avenue site for the Long Island converter station. This alternative site, located adjacent to Duffy Avenue in the Town of North Hempstead, is currently being considered as a replacement the previously proposed Cedar Creek converter station. The supplemental analysis performed by EDR is designed to address the same questions evaluated in the original study, specifically:

1. From what locations could the proposed facility potentially be seen?

2. What sensitive receptors might have views of the proposed facility?

3. What will the proposed facility look like?

4. What is the potential visual impact of the project?

The study undertaken by EDR addresses these questions through, field evaluation, computer- assisted visual simulations and line-of-sight cross sections.

Project Location/Study Area

The proposed Duffy Avenue converter station site is located east of the Wantagh State Parkway at 508 Duffy Avenue, in the Town of North Hempstead, Nassau County, New York. The site is located within an industrial/commercial section of the Town of North Hempstead. It is owned by the New York State Office of Parks Recreation and Historic Preservation (OPRHP) and is currently being leased to the New York State Department of Transportation (NYSDOT). The Duffy Avenue site includes several one-story buildings and a salt storage structure, which is estimated to be approximately 45 feet in height. The northern portion of the site is characterized by mowed lawn with some successional vegetation (young trees and shrubs) along the perimeter. This site is bounded by the Wantagh State Parkway, Long Island Railroad tracks, roadways, and commercial/industrial enterprises.

For the purpose of this VIA, the area within one mile of the proposed facility was defined as the Study Area. This distance was considered adequate given the screening effect of existing vegetation and structures in this highly developed area. The area within one mile of the proposed Duffy Avenue site includes institutions (e.g. schools), the Wantagh State Parkway, residential neighborhoods, commercial/industrial facilities, and parks. Dominant land use within the Study Area is suburban residential and commercial/industrial. Generally, adjacent neighborhoods include moderate density, single family homes and streets lined with concrete curbs, sidewalks, and mature street trees. Commercial/industrial land uses are generally located along Prospect Avenue, Old Country Road, and Duffy Avenue. A heavily industrialized area is bounded by Old Country Road, Wantagh State Parkway, the Long Island Railroad tracks and Grand Boulevard. The commercial/industrial areas within the Study Area are generally characterized by an abundance of pavement and high to moderate density 1 to 2 story structures with flat roofs. Vegetation, including turf, within these areas is generally lacking. Topography in the Study Area tends to be flat with few visible water features (i.e. ponds). Project Description

The Neptune Project involves the construction of a 600-MW high-voltage direct-current (HVDC) submarine/underground power transmission cable to connect load centers in New York with transmission and generation resources in New Jersey. From the New York landfall point, the direct current (DC) cable would run underground north within the Wantagh State Parkway right-of-way (ROW) for approximately 9.2 miles to the proposed Duffy Avenue site. A DC-alternating current (AC) converter station would be constructed on the Duffy Avenue site east of the Wantagh State Parkway. An AC cable would exit the converter station and proceed underground south, within the Wantagh State Parkway ROW parallel to the DC trench (approximately 15 feet apart), approximately 1.7 miles to the Newbridge Road Substation. The proposed converter station is the only above- ground facility on the proposed transmission route.

The converter station will consist of several new structures, similar to those described in previously submitted Visual Impact Assessments for the Neptune Project (EDR, 2002 A and 2002 B). The building heights are variable, but it is anticipated that heights will not exceed a maximum of approximately 64 feet and the tallest transmission structure will reach approximately 88 feet above existing ground level. Although final design of the facility has not yet been completed, the proposed site plan and architectural elevations are presented in Appendix B.

Visually Sensitive Resources/Intensive Land Uses

Based on review of existing data sources, it appears that the Study Area generally lacks aesthetic resources of statewide significance, as defined by the New York State Department of Environmental Conservation (NYSDEC) program policy DEP-00-2 (NYSDEC, 2000). Within the Study Area, there are no State Parks, no state or federally designated trails, no Urban Cultural Parks, and no sites/structures listed on the State and National Register of Historic Places. There are also no State Wildlife Management Areas, National Wildlife Refuges, National Natural Landmarks, National Recreation Areas, National Seashores, designated Wild, Scenic or Recreational Rivers, or designated Scenic Areas of Statewide Significance (NYSOPRHP, 1997; ECL Article 15 Title 27; NYSDOS, 1993). However, the Wantagh State Parkway and the Northern State Parkway are both legislated as New York Scenic Byways (NYSDOT, not dated). The Wantagh State Parkway has also been determined eligible for listing on the State and National Register of Historic Places. These roads are the only aesthetic resources of statewide significance located within the Study Area.

The Study Area also includes several areas that are considered visually sensitive due to their local significance or their intensity of land use. These sites are listed in Table 1 and their location indicated in Figure 2. They include two parks/recreational facilities, one golf course, four public schools, several highly traveled roadways, and one residential neighborhood. Table 1.

Road distance are measured from the point nearest the site.

Park and recreational facilities within the Study Area are limited. However, those facilities that do exist offer a wide range of activities for the local community. Cantiague Park, located northeast of the proposed sites, is accessible from West John Street and Cantiague Rock Road. Cantiague Park is a county park that features an Olympic-sized pool, indoor skating rink, a children's play area, bocci ball courts, tennis and basketball courts, softball and soccer fields, and golf facilities (discussed below). The park also includes passive recreational facilities such as picnic areas, and bicycle/walking paths (Nassau County Web Site). In addition to the recreational opportunities described above, Cantiague Park includes a full service golf course. Facilities at the Cantiague Park Golf Course include a driving range, nine-hole golf course and an 18-hole miniature golf course (Nassau County Web Site). Both the Cantiague Park and the golf course generally contain scattered mature trees. The Martin "Bunky Reid Park is located west of the proposed sites at the comer of Broadway and Urban Avenue. This neighborhood park contains limited vegetation and features ball fields, play equipment, basketball courts and a pool.

Schools within the Study Area are also considered visually sensitive sites. The Westbury Middle School and Park Elementary School are located within the Westbury Union Free School District. These schools are located west and northwest of the proposed site, respectively. The Old Country Road Elementary School is located southeast of the proposed site, within the Hicksville Union Free School District. The Joseph M. Barry Career and Technical Education Center (Nassau County B.O.C.E.S.) is located north of the proposed site along Prospect Avenue.

Several heavily traveled transportation corridors bisect the Study Area. These corridors include the Wantagh State Parkway, Northern State Parkway, Prospect Avenue/West John Street, Old Country Road, and Brush Hollow Road. These transportation corridors, which vary from two lane roads to six lane divided highways, are heavily used by local residents, commuters and through-travelers. The Wantagh State Parkway (four lanes) and the Northern State Parkway (six lanes) are divided, limited access highways, and are the largest highways within the Study Area. The Wantagh State Parkway is the main route to Jones Beach and Northern State Parkway is an east-west thoroughfare that connects Haupauge to New York City. Both of these parkways are listed as New York State Scenic Byways. Other roadways within the Study Area generally consist of less heavily traveled residential streets. One residential neighborhood within the Study Area is also considered to be a visually sensitive resource. This is due to its proximity to the proposed converter station and the potential sensitivity of the residents. This neighborhood is located northwest of the proposed Duffy Avenue site and the/Wantagh State Parkway, north of the Long Island Railroad tracks, and south of Prospect Avenue.

Methods

Field Evaluation

To evaluate the potential visibility of the proposed project, the area within a one mile radius of the converter station site was field reviewed on January 22, 2003. The field evaluation involved 1) visiting locally sensitive resources/intensive land uses, 2) investigating potential visibility of the proposed project from roadways and other publicly accessible areas, and 3) photographically documenting views in the direction of the proposed site from various locations throughout the Study Area (see Figures 3 and 4). The existing salt storage building on the Duffy Avenue site was used as a locational reference point. Photos were taken from 76 viewpoints within the study area (a total of 80 sites were visited). Selected viewpoints typically offered the most open, unobstructed views of the project site, and/or included areas identified as visually sensitive, or having a high level of public visitation. Viewpoint locations within the study area are shown in Figure 3. The photos obtained during this field evaluation were used to assist in determining where the proposed converter station might realistically be visible, and which viewpoints would be appropriate for use in the preparation of visual simulations and line-of-sight analyses.

Visual Simulations

The photos obtained during the field evaluation were reviewed to determine which offered typical, relatively unobstructed views toward the proposed facility. This determination was based on the visibility of the existing built salt storage structure located on the proposed site. Of those views where it was determined that the converter station might be visible, the most representative views were selected for the development of computer-assisted visual simulations.

To show anticipated visual changes associated with the proposed project, high-resolution computer- enhanced image processing was used to create realistic photographic simulations of the proposed facility from the selected viewpoints. The simulations were developed by creating a three- dimensional model of the proposed buildings and equipment, based on dimensions, site plans and elevations provided by Siemens and Oest Asociates (see Appendix B). EDR used AutoCAD 2000® and 3D Studio Max (Version 4.2)® software to create the computer model. The model was then superimposed on digitized photographs of the existing landscape using the location and angle of the camera view (determined using field mapping and GPS data collected during the fieldevaluation). The photographs were taken with a 35 mm camera with a 50 mm lens to accurately represent scale perceived by the human eye. A "wire frame" model of the converter station and select existing site features was built using year 2000 aerial photography and site plan information provided bySiemens. This was then superimposed over the photos to further refine the camera alignment and to assure that project elements are shown in proportion, perspective, and proper relation to the existing landscape elements, which will remain. Consequently, the alignment, elevation, and location of the visible elements of the project are true to the proposed design and accurate in size and location. To the extent possible, surface color, texture, and shading of the modeled facilities were selected to replicate those proposed by Oest Associates. Line-of-Siqht Cross Sections

From selected sites on either side of the proposed Duffy Avenue converter station, line-of-sight cross sections were prepared. Cross section locations were chosen to show the range of topographic, vegetational, and/or structural screening conditions that exist in the area, and to include resources that could be considered visually sensitive. Vegetation, structures, and topography are accurate in terms of height and location based on USGS mapping, year 2000 aerial photos and the proposed site plans. However, the vertical scale was exaggerated 20 times to improve the accuracy of the analysis (see Figure 9).

Results

Field Evaluation

Based on EDR's field review, it appears that visibility of the proposed Duffy Avenue converter station will be limited due to effective screening provided by existing vegetation and/or structures in most areas. The project site was not visible from most of Bush Hollow Road, West John Street, residential neighborhoods, and schools within the Study Area. This was determined by using existing buildings on and adjacent to the site as reference points (see photos included in Figure 4).

Based on field analysis, open views of existing buildings on the site are generally limited to adjacent properties/roadways, a small section of the Wantagh State Parkway and the Old Country Road bridge over the Wantagh State Parkway. Views of the site also appeared to be available from certain locations within Cantiague Park. Views from the roadways are short in duration and peripheral, as road alignment, traffic, and road speed tend to preoccupy drivers and their passengers. Consequently these views and viewers should not be significantly impacted by the proposed project. The project will be clearly visible from some adjacent commercial/industrial properties. The significance of these views will also be limited, as employees at these facilities may or may not have views to the outside, and will typically be focused on their job responsibilities. Open and screened views of the converter station may be available from portions of the Cantiague Park Golf Course, and if so, have the potential to adversely affect users of this facility. Due to the industrial nature of most of the surrounding area, if visible, the project will not contrast significantly with existing land use/aesthetic character. Field review suggests that the project will not be visible from the remainder of Cantiague Park. Some locations in adjacent residential areas may have views of the proposed project. However, these views are limited because of effective screening provided by existing vegetation and structures within the residential areas. Those residential areas that appear to have the greatest opportunity for viewing the proposed project are located immediately north of the project sites and those located immediately west of the Wantagh State Parkway.

Simulations

Five representative viewpoints within the Study Area were selected for development of visual simulations (see Figure 5). These included the following:

Viewpoint 13 - Cantiague Park

Viewpoint 29 - Park Elementary School

Viewpoint 35 - Edge of Residential Neighborhood

Viewpoint 49 - Duffy Avenue Viewpoint 67 - Old Country Road Overpass (over the Wantagh State Parkway)

These viewpoints were selected because field review suggested potential visibility of the proposed converter station and/or they were located in visually sensitive areas or areas of intensive land use. Camera alignments performed by EDR revealed that the proposed facility will be completely screened from viewpoints 13, 29 and 49. As indicated by the green "wire frame" model of the facility in Figure 6, the converter station will fall behind foreground structures in all these views. Figure 7 shows a photo "rendering" of the proposed facility from Viewpoint 35 (indicated as such because the image may contain some minor alignment errors due to a lack of locationai references in the photo). As the rendering illustrates, from this location, which is the closest, most open view from the neighborhood to the west, the proposed converter station will be well screened by foreground vegetation that borders the Long Island Railroad tracks. Even with leaves absent from the trees, the buildings and towers on the site are obscured and do not significantly change the visual character of this view. This will be the case, even if the horizontal and vertical alignment of the facility is not exactly as shown in Figure 7.

Only in Viewpoint 67 (Figure 8) is the proposed Duffy Avenue converter station clearly visible. From this elevated foreground viewpoint, the majority of the main building is visible. However, ground- level features remain screened by vegetation that borders the Wantagh State Parkway, and other proposed structures on site are largely screened by the building itself. The proposed project clearly adds a new built element to the landscape, and the building is significantly larger that other existing structures in the area. However, its level of contrast is limited by the fact that it is being added to a landscape that is already developed and dominated by built features. In addition, the colors, materials and architectural features of the building (e.g. earth tones, windows, peaked roofs) help break up the building mass and are compatible with existing commercial and residential structures in the area. The facility looks more like a commercial office building than a utility structure and should not adversely affect any land use of viewer activity in the area.

Line-of-Sian Cross Sections

Two line-of-sight cross sections were prepared for the Duffy Avenue converter station in order to illustrate and confirm the results of earlier analyses. The cross sections included in Figure 9 indicate that throughout most of the Study Area, visibility of the proposed buildings/structures will be limited due to screening provided by existing buildings and tree foliage. Lack of visibility from sensitive sites, such as the residential neighborhood to the west, Park Elementary School, Wantagh State Parkway and Cantiague Park, was confirmed by this analysis. The cross sections also show that potential ground level views will be available only in open areas that are within 0.5 mile of the site. The majority of these areas are already dominated by commercial/industrial land use.

Conclusions

The visual impact assessment performed by EDR indicates that the proposed converter station will not significantly change the existing visual/aesthetic character of the Study Area. While there will be a few open and partially open views of the facility, the overall visibility of the converter station will be limited. This is due to 1) the relatively flat topography within the study area, which results in few elevated viewpoints, 2) the effective screening provided by existing structures and/or vegetation in the surrounding area, and 3) the distance and screening (vegetation and built structures) that exists between the site and most of the sensitive resources/viewer locations within the Study Area. As indicated ih the simulation from Viewpoint 67 (Figure 8), the proposed converter station will be a large facility that alters the visual character of certain foreground views. However, its scale contrast and any perception of changed land use are minimized through 1) its occurrence within an existing commercial/industrial area, 2) architectural treatments that are consistent with residential and commercial structures in the area, and 3) the commitment of the applicant to propose a final design that will blend in, as much as possible, with the existing structures/landscape in the area. Limited visual impact is also attributable to the fact that the site is not easily visible from Duffy Avenue, has limited sensitive receptors adjacent to the property and contains an existing structure that is comparable in height to the tallest proposed building. However, to minimize visual impact the final design of the proposed facility should 1) utilize the smallest building footprints and heights possible, 2) conform with any design guidelines utilized by the local municipality, 3) utilize materials and colors that minimize contrast with existing facilities/landscape features, 4) limit removal of existing vegetation, and 5) include landscape plantings around the converter station periphery to maximize screening from adjacent viewers.

4.13 Noise 4.13.2 Town of Hempstead Noise Standards and Criteria Chapter 38 of the Town of North Hempstead Code (the Code) prohibits the operation of any machinery, equipment, pump, fan, exhaust fan, air-conditioning apparatus, or similar mechanical device in such a manner as to create any noise exceeding 50 decibels at the adjoining property line (Town of North Hempstead 1968). Under the code, the noise level during the converter station operation, as decibels of sound pressure, cannot exceed 50 decibels at any point along the perimeter of the parcel boundary.

4.13.2.1 Existing Conditions The Duffy Avenue Converter Station site is located at 508 Duffy Avenue in the Town of North Hempstead, County of Nassau, Long Island, New York. The converter station site is located approximately 1.7 miles north of the Newbridge Road substation along the east side of the Wantagh State Parkway, within an industrial/commercial section of the Town of North Hemp- stead. The converter station site will be located on a parcel, owned by the New York State Of- fice of Parks, Recreation and Historic Preservation, which is bounded on the north by the Long Island Railroad, on the east by existing industrial development, on the south by Old Country Road, and on the west by industrial development and a forested buffer along the west side of the Wantagh Parkway. Neptune will operate the converter station facility on a portion of this parcel described throughout this document as the site. For the purposes of the noise code, the noise level during the converter station operation cannot exceed 50 decibels at any point along the perimeter of the parcel boundary. The parcel boundary and site boundary are depicted in Figure 4.13.

4.13.2.2 Potential Impacts and Mitigation Potential adverse noise impacts of the proposed Neptune RTS• project would be limited to commercial areas in the immediate vicinity of the Duffy Avenue Converter Station. Increased noise levels associated with construction of the converter station would be temporary. During operation, steady noise will be emitted from mechanical equipment (e.g., converter transformers,

02:001412_EA01_07_02-BU31 4.13-1 EXHIBIT_4.13Duffy.doc-06/27/03 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Exhibit 4 Supplement - Environmental Impact transformer oil coolers, valve coolers, smoothing reactors, and AC harmonic filters). To minimize noise impacts during construction, construction operations conducted outside of building walls subject to the need to complete tasks already started that cannot be readily interrupted will be limited to the hours between 7:00 a.m. and 6:00 p.m. To mitigate the noise impact from operation of the station, the converter station will be designed to conform to Chapter 38 of the Town of North Hempstead Code. In addition, once the station is operating, noise levels will be measured at the property boundaries to ensure that these design goals have been met. Specific measures that will be taken to ensure compliance with all applicable regulations will be provided in the Environmental Management and Construction Plan. Figure 4.13-1 depicts station noise levels, at locations around the station and at the cor- ners of the property parcel, that have been developed based on noise modeling results. The model input includes noise source power and geometric location, receptor locations, barriers, re- flectors, and ground and atmospheric conditions. With the mitigation design measures included in the model, sound levels at the perimeter were projected to be within the North Hempstead Code requirements. Noise levels will meet the town code at the property boundary and will be even lower at the nearest sensitive receptors. As depicted in Figure 4.13-1, some commercial operations will receive 42-48.9 dBA. This noise level is within the range commonly found in a suburban neighborhood at night (40-50 dBA).

4.14 Public Health and Safety This section addresses the potential for impacts to public health and safety, including public access to the facility, electromagnetic fields (EMF), and fire safety.

Public Access The public will be protected from direct contact with the HVDC and HVAC cables because they will be buried under water and sediment in the marine portions and in underground trenches in the upland portions of the route. (See Exhibits 2 and E-3 for route locations and underground installation techniques.) Warning marker tapes and a layer of concrete slabs will protect against accidental contact, due to construction activities or unauthorized digging, in upland portions of the route. Both submarine and upland cable routes will be duly recorded and the information regarding the cable will be made available for authorized work. Upland portions of the cable routes will be marked. The upland cable route will be marked every 300 to 500 feet with plastic route markers to identify the as-built location of the cable. A sticker will be attached to each marker that identifies the owner, type of utility, and a contact number. Detailed information on route markers has been included in Exhibit E-3. The cable will be registered with the NYS "call before you dig" program in compliance with 16 NYCRR PART 753 - Protection of Underground Facilities. At each end of the route, the cables will leave the trench and be terminated within a secured area of the substation/converter station accessible only to trained, authorized personnel. Vehicular access will restricted by fencing. The converter station and all associated equipment will be contained within an enclosure wall. The Newbridge Road substation is also a fenced facility with a passkey-operated security gate and access is restricted to authorized personnel.

Fire Protection The Duffy Avenue Converter Station is being designed to meet all applicable fire codes including the NYS Uniform Fire Prevention and Building Code. Neptune RTS• will meet with the North Hempstead fire chief to review potential fire protection designs and systems and will continue to work closely with local agencies to finalize design details. In general, the fire protection system will consist of automatic detection and fire-fighting equipment. The fire-detection

The fire alarm will be initiated automatically by smoke, heat, or flame detectors or manually by pushbuttons. A combination of detectors will be used, depending on the equipment or room. They will include infrared detectors, ultraviolet detectors, air sampling systems, ionization and optical smoke detectors, and rate-of-rise tempera- ture-sensitive fire detectors. Audible alarms and flashing lights will be activated in the case of an incident. The room or equipment triggering the alarm will be indicated on the control panel. The equipment will be switched off and, if high-voltage equipment, it will be grounded. Automatic firefighting will start automatically and will use water or an appropriate gas-extinguishing agent. Fire detectors and automatic firefighting equipment will be connected to a power supply within the fire-detection control panel, which is connected to the mains via a power supply/battery charger unit with an internal rechargeable 24 V battery. A pump house will be included within the facility and two electrically driven water pumps will supply water. A diesel-driven pump with the same capacity as the electric pumps will provide backup. This fire-protection water system will be independent of all other water systems. Detailed information regarding fire protection and emergency response procedures will be provided in the EM&CP. Neptune will continue consultations with local fire and safety officials.

ElectroMagnetic Fields (EMFs) There are no changes to the impacts resulting from electromagnetic fields associated with the DC cable due to the relocation of the converter station to the Duffy Avenue site. The DC Ca- ble, because of its design, results in zero external magnetic field beyond its 7-inch casing. Be- cause the DC cables connected to the converter station are of underground shielded design external electric fields are also zero. Potential impacts of electric and magnetic fields that may result from (1) location of the converter station itself to the Duffy Avenue site, and (2) installation of a 1.7-mile, 345-kV underground AC tie-in, which would connect the Converter Station to the Newbridge Road Substation, are different from those discussed in the original Application as discussed below. An analysis was performed in January 2002 by Electric Research & Management, Inc. (ERM) of Pittsburgh, PA to evaluate the impacts of DC electric and magnetic fields emanating

from the HVDC interconnections as then proposed. That report did not address the impacts associated with the HVAC cable as no HVAC cable was used in the initial system design. A report analyzing the electric and magnetic fields for the HVAC cable and the HVAC tie to the Duffy Avenue site was prepared by ERM in June 2003. The findings of the ERM reports are summarized in the sections below; the report is included at the end of this section.

4.14.1 EMFs EMFs are non-ionizing radiation produced by equipment, devices, and appliances that transport, utilize, or transform electricity. Examples of levels of EMFs from everyday activities are shown in Table 4.14-1.

* Dash (-) means that the magnetic field at this distance from the operating appliance could not be distinguished from background measurements taken before the appliance had been turned on. ** Some appliances produce both 60-Hz and higher frequency fields. For example, televisions and computer screens produce fields at 10,000-30,000 Hz (10-30 kHz) as well as 60-Hz fields. *** Microwave ovens produce 60-Hz fields of several hundred milligauss, but they also create microwave energy inside the appliance that is at a much higher frequency (about 2.45 billion Hz). We are shielded from the higher frequency fields but not from the 60-Hz fields. **** Most digital clocks have low magnetic fields. In some analog clocks, however, higher magnetic fields are produced by the motor that drives the hands. In the above table, the clocks are electrically powered using alternating current, as are all the appliances described in these tables.

Wires and cables that carry electricity produce EMFs. The two fields are produced con- currently by cables transmitting electric power, and the relative directions of lines of force of the two respective fields are perpendicular, or 90 degrees (adapted from Halliday and Resnick 1978). Electric power is usually generated, delivered, and utilized as an alternating current (AC) system in which currents and voltages vary at the power frequency of 60 cycles per second (hertz [Hz]). Electric and magnetic fields associated with AC systems also vary at the power frequency and, thus, are referred to as AC fields. Direct current (DC) electric systems are also utilized to transfer electric power due to its efficiency advantage at high voltages and over long distances. In DC systems, the operating voltage is constant and the direction of current flow is constant for a given direction of power flow. DC electric systems produce DC electric and magnetic fields. The electric fields are essentially constant and magnetic field vectors have a constant direction with a magnitude proportional to the DC current on the system. While there are no federal standards for AC electric and magnetic fields, two states, Flor- ida and New York, have standards for electric and magnetic fields produced by high-voltage AC transmission lines. Voluntary guidelines for human exposure to AC and DC electric and mag-

The New York PSC has issued a Statement of Interim Policy on Magnetic Fields of Major Electric Transmission Facilities (September 11,1990) and Commis- sion Opinion No 78-13 (June 19,1988), which establish guidelines for evaluating impacts associated with EMFs from AC transmission lines. The New York PSC interim standard applies to the AC tie that connects the Duffy Avenue Converter Station to the Newbridge Road Substation. The only relevant issues for the DC interconnection are compliance with the voluntary human exposure guidelines and the environmental impact, mainly the possibility of interference with navigation instruments that use the earth's magnetic field.

4.14.1.1 HVDC Cable

Existing Environment The integrated return conductor (IRC) cable designed by Nexans for this project is described in Exhibit E-l. The cable has an inner circular segmented copper conductor that is the high-voltage supply conductor and an outer segmented return conductor that is concentric with the inner conductor. The two conductors are separated by mass-impregnated paper insulation. With the integrated "return" conductor, only one cable is required for a DC interconnection. As described in Exhibit E-l and the attached EMF reports, the proposed cable produces no external DC magnetic or electric fields.

Potential Impacts and Mitigation Because the DC cable does not produce electric or magnetic fields there is no risk to human health and safety from this component of the system. With no external magnetic field, there is no chance for interference with waterway navigation based on instruments that use the earth's geomagnetic field or for interference with implanted medical devices in people (e.g., pacemak- ers).

4.14.1.2 AC Interconnections

Existing Environment Underground AC Cable There will be an approximately 1.7-niile, 345-kV underground AC interconnection between the Duffy Avenue Converter Station and the Newbridge Road substation. The underground, shielded design results in external electric fields of zero and is not of concern. Modeling and analysis were performed by ERM to predict AC magnetic fields emanating from the AC interconnection. Two trefoil configurations and one flat configuration are being considered for the underground AC tie-in. Magnetic fields for each of these configurations have been modeled at varying installation depths. Using the worst case trefoil arrangement, at 3 feet above ground level, the fields would not exceed the PSC interim standard of 200 mG at a 3 foot installation depth. If the trefoil cable is buried to 4 feet the field will be about 100 mG at 3 feet above ground level (the equivalent of an electric shaver). Twenty-five feet on either side of the cable the field will be less than 25 mG. Using the flat configuration and measuring at 3 feet above ground level, the fields would not exceed the PSC interim standard of 200 mG at a 4.5 foot installation depth. If the trefoil cable is buried to 5 feet the field will be about 170 mG measured at 3 feet above ground level (the equivalent of an electric drill). See June 2003 ERM report attached to this section.

Duffy Avenue Converter Station The DC cable will terminate at the Duffy Avenue Converter Station, where power will be converted to AC current. Electric fields will be created in some areas within the converter station; however, the electric fields are negligible at the fence line, which is the point where they are measured for compliance with the PSC interim standard. ERM calculated the AC magnetic field at 10-foot intervals around the fence line of the converter station (see Figure 3 of the ERM report) assuming a 1250 A load, a flat AC cable configuration and a burial depth of 4 ¥2 feet. The magnetic field is less than 10 milligauss (mG) along the fence line, with the exception of the portion of the route that parallels and crosses the AC tie-in. The maximum magnetic field level calculated along the fence line was 191 mG and

02:OOI412_EA01_07_00 4.14-7 EXHIBITjt. 14Duffy.doc-06/27/03 Neptune Regional Transmission System LLC Article VU Application Second Supplement June 2003 Exhibit 4 Supplement - Environmental Impact occurs where the AC tie-in crosses the fence line. Therefore, the station would not exceed the PSC interim standard for magnetic fields which is 200 mG. As noted in Table 4.14-1 this is about one-half of the field produced by a typical hairdryer. The magnetic field was also calculated at the fence line assuming a 1250 A load, and two alternative trefoil configurations at a burial depth of 4 feet. The maximum magnetic fields where the AC cable crosses the fence line were 143 mG with one configuration and 93 mG with the other.

Newbridge Road Substation The AC cable terminates at the AC grid in the Newbridge Road Substation. Design details for the connection to the Newbridge Road Substation are not yet available. Electric fields from the AC cable would be zero until they reach the uninsulated conductors within the substation. Magnetic fields at the perimeter of the substation are expected to be similar to those at the Cedar Creek Converter Station, with a peak directly above the cable as it crosses the property boundary.

Potential Impacts and Mitigation AC electric fields are negligible at the fence line of the facility and magnetic fields would not exceed the PSC interim standard at the fence line of the facility. As described above, access to the site will be restricted to trained, authorized personnel. Thus, no impacts associated with AC electric or magnetic fields are expected at the converter station. The underground, shielded design of the AC cable results in external electric fields of zero. The underground AC cable will be installed at a depth sufficient to ensure compliance with New York State standards directly above the cable. Magnetic fields will more than meet NYS interim guidelines at all schools and residential receptors. Because there will be no above- ground electric fields produced by the AC line and magnetic fields will be well below NYS PSC standards, there will be no adverse impacts associated with EMFs. Since electric fields from the AC cable would be zero until they reach the uninsulated conductors and the connection will be designed such that the magnetic field does not exceed the 200 mG standard, no impacts associated with AC electric or magnetic fields are expected at the Newbridge Road substation.

Prepared June 25, 2003 Introduction

A proposed high voltage DC link will deliver electric power between Sayreville and Long Island. On Long Island, the buried DC transmission line will terminate at the proposed Duffy Avenue converter station where the DC power is converted to AC. A plan view of one possible layout of the station is shown in Figure 1 of this report. A project plan is provided in Exhibit 2 of the Duffy Avenue Supplemental Article VU application. The DC cable from Sayreville terminates inside the Duffy Avenue station at a high voltage pothead where the high voltage and ground conductors are separated for connection to switching equipment, a smoothing reactor, and finally the converter valves. The converter valves create pulses that, through converter transformers, become an alternating twelve-pulse output (AC). From the transformers, cables run to a gas- insulated substation (GIS) that provides system protection along with the interconnections to three filter banks, a shunt reactor, and the 345kV AC tie. This tie connects the AC output from the converter station to the AC grid at the New Bridge Road substation.

This report documents calculations used to estimate the AC magnetic fields around the fence line of the Duffy Avenue station and above the AC cable tie that runs to New Bridge Substation. DC magnetic field calculations are not required because the DC cable, running from Sayreville to Long Island, utilizes an integrated return conductor (IRC) that results in zero external magnetic field under normal balanced current conditions, and because the Duffy Avenue station is sufficiently distant from water that interference with navigation is not an issue. The New York State PSC interim standard for electric and magnetic fields addresses only 60 Hz fields. For the AC field calculations, converter station equipment and layout information was obtained from Siemens AG, the equipment supplier, and cable design information was obtained from Nexans, the cable supplier for this project.

Because both the DC and AC ties connected to the Duffy Avenue converter station are of underground shielded design, external electric fields are zero. At the converter station, significant electric fields occur beneath the 345 kV conductors from the transformers to the GIS, and beneath the connections to the filter banks and shunt reactor. However, at distances corresponding to the station fence line of the converter station, the electric fields are expected to be negligible. Thus, electric fields are not modeled in this report.

The remainder of the report describes the models used to estimate AC magnetic fields produced by the converter station and the AC tie. Filter Banks

Figure 4 shows the basic horizontal flat configuration currently proposed for the AC tie cables. Figure 5 is a graph showing calculated AC magnetic field resultant along a profile that crosses a long straight run of the AC tie with three different burial depths. The magnetic fields are evaluated at a height of three feet above ground level with 750 MW load current of 1250 A on each phase conductor. For the calculated values shown in Figure 5, the burial depth of 4.5 feet (or greater) is necessary to keep magnetic fields below the 200 mG New York interim standard level at 1250 A of current. The maximum value directly over the centerline with the cables at a depth of 4.5 feet is 191 mG.

(wt /^ CABLE IN Fur Figure 4 Flat horizontal configuration for AC tie cables.

Two alternate configurations are being considered for the underground AC tie, as shown in Figure 6. The first is a direct-bury configuration with three cables laid in a trench in a trefoil arrangement, one cable on top of two. In the second configuration, the cables are pulled in polyethylene (PE) conduit, with the conduits in a trefoil arrangement. From a magnetic field standpoint, the main difference between the two methods is simply the separation between phase conductors, with the cables in conduit having a slightly larger separation by virtue of the conduit diameter. In both cases, the magnetic fields are relatively low.

Figure 7 is a graph showing calculated magnetic fields along a profile that crosses a long straight run of the AC tie at a height of three feet above ground level. Both configurations use the worst-case 750 MW load current of 1250 A. For the calculated values shown in Figure 7, the burial depth is 4 feet to the top of the first conductor. The two configurations (B) and (C) have maximum fields of 93 mG and 143 mG, respectively.

To determine the impact of changes in the burial depth for the two alternate configurations, maximum magnetic fields directly over the cables were calculated at a height of three feet above ground level, centered over the cables, for burial depths of 1 to 4 feet (distance from ground level to top of first underground conductor) for the two configurations. Figure 8 shows the rms resultant magnetic field directly over the underground cables at a height of three feet above ground level for the four burial depths. The 200 mG New York interim standard is not exceeded with either configuration with a minimum depth of 3 feet, but the limit is exceeded with (C) at a 2 foot burial depth.

New Bridge Road Substation Electric and Magnetic Fields

Currently, design details for the AC tie connection at the New Bridge Road substation are unavailable. Assuming that the AC tie from the Duffy Avenue converter station enters the substation underground, magnetic fields along the substation fence line will peak directly above buried tie cables. Thus, estimated magnetic field levels at this location will be similar to those calculated for the Cedar Creek station and presented in AC Electric and Magnetic Fields Calculations for Cedar Creek Converter Station and AC Tie Report (November 21, 2002) (depending on burial depth).

As stated previously, electric fields from the shielded AC tie cables will be zero until the transition is made to uninsulated conductors within the substation.

When, specific plans for the layout of the AC tie connection are available, this evaluation will be updated. Calculated AC Magnetic Field Flat Horizontal Configuration with 0.82 ft Phase-to-Phase Spacing

02:001412_EA01_07_02-B1132 EXHIBrr_7_Duffy.doc-06/27/03 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Exhibit 7 - Local Ordinances

EXHIBIT 7 - LOCAL ORDINANCES This exhibit identifies and addresses compliance with the local laws, rules, and regulations that pertain to the construction and operation of the Duffy Avenue Converter. As described herein, the converter station will comply with the substantive requirements of applicable local laws, rules, and regulations with three exceptions: building height; fence height; and parking. Pursuant to Section 130 of the Public Service Law, no municipal agency may require any approval, permit, or consent for the construction or operation of a facility subject to Article VII approval. This exhibit also identifies the local approvals that would be required in the absence of preemption under Section 130.

7.1 Laws, Policies, and Regulations The following laws, policies, and regulations were consulted:

• The Code of the Town of North Hempstead New York,

• The Nassau County Comprehensive Master Plan.

7.1.1 Property Descriptions The Duffy Avenue Converter Station would be constructed on approximately an 18-acre parcel of land owned by the New York State Office of Parks, Recreation and Historic Preserva- tion adjacent to the Wantagh State Parkway (see revised Figure 2-3). The Duffy Avenue Site is located at 508 Duffy Avenue in the Town of North Hempstead, County of Nassau, Long Island, New York.

7.2 Applicable Local Requirements 7.2.1 Code of the Town of North Hempstead, New York The Town has not zoned the Duffy Avenue Converter Station site because it is owned by the State of New York. Accordingly, the restrictions that would apply by virtue of the zoning law. Chapter 70 of the Town Code, are not applicable. Nevertheless, but without waiving any rights, Neptune RTS• will address the compliance of the proposed converter station with the provisions of Chapter 70 applicable to the Industrial B Zone. The parcels surrounding the site

02:001412_EA01_07_02-B1132 7-1 EXHIBIT_7_Dufiy.(ioc-06/27/03 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Exhibit 7-Local Ordinances are zoned as Industrial B. The current use of the site is consistent with that designation. Chapter 70, Article XX, provides the requirements governing buildings and structures within an Industrial B district.

Chapter 70 of the Town of North Hempstead Code - Zoning Code The converter station's compliance with Article XX, Sections 70-185 through 70-195, of the Code of the Town of North Hempstead is discussed below.

§70-185-Application of Provisions. States that the provisions of this Article apply in an Industrial B District

§70-186 - Permitted and prohibited uses. States that a building may be erected and a lot or premises may be used for any lawful purposes except those listed in this section which are prohibited or those that are noxious or offensive by reason of the emission of odor, dust, smoke, gas or noise. Utility or converter station use is not listed as prohibited. Operation of the project will not produce the emission of odor, dust, smoke or gas. While the project will produce noise, final design of the converter station will meet the Town of Hempstead Noise Code. See Section 4.13 of this Supplement for a further discussion of noise.

§70-187 - Conditional Uses and §70-188 - Additional Conditional Uses. State that a building may be erected, and a lot or premises may be used for any purposes listed in this section only when authorized by the Board of Zoning and Appeals (70-187) or by the Town Board (§70- 188). Although central station power plants are listed as a conditional use, electric transmission facilities are not. Therefore, they are allowed without need for specific approval.

§70-189 - Accessory Uses. This section states that accessory uses on the same lot with and customarily incidental to any permitted use will be allowed. §70-189.1 - Parking Require- ments states that parking shall be provided as outline in section 70-103. This states that indus-

02:001412_EA01_07_02-B1132 7-2 EXHIBIT.7_Duffy.doc-06/27/03 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Exhibit 7-Local Ordinances trial buildings must supply one parking place for every 600 square feet of floor area. This requirement, if not waived, would result in the creation of more parking than is reasonably necessary for a converter station facility that will not have 4 employees per shift and will not be visited by any more than 10 people at any one time. The applicant proposes to provide 15 parking places and to the extent that this site is to be treated as zoned Industrial B, requests a finding that this requirement is unreasonably restrictive. Details will be provided in the final site plan to be included in the EM & CP.

§70-190 - Height. This section states that no building structure or part thereof shall exceed 40 feet in height. The Project will include a building with a maximum height of 64 feet and switchyard masts at a height of 86 feet. Therefore, if the site were zoned Industrial B, a variance would need to be sought for this requirement. Although the lot is not zoned, Neptune RTS• demonstrates here why compliance with this restriction would be unreasonable and why the PSC can make the finding provided for in Public Service Law §1261.(f). The height of the tallest building within the converter station - 64 feet - is dictated by the physical space requirements in the design of the primary conversion equipment, the vertically aligned thyristor valves, and the AC voltage levels involved. The number of silicon wafers within the valves, the space between the wafers and the space that must be maintained between the lowest wafer and the ground are fixed and dictate a 64-feet height. Nor can the building height be reduced by building below grade. The equipment at issue must be available at grade for maintenance and repair. The switchyard masts must be at the specified heights to maintain appropriate safety clearances from adjacent equipment and underlying access ways.

§70-191 - Lot coverage. This states that the lot coverage area shall not exceed 80% of the lot area and the lot area must be a minimum of 10,000 square feet. The Project will comply with these requirements. Details will be provided in the final site plan. The acreage of the site is approximately 18.31 acres (as shown on the project plan for the leased area not the parcel) the area bound by the facility wall is 4.5 acres or approximately 25% of the site.

§70-192 - Yard requirements. This requires a minimum front yard setback of ten (10) feet and a rear yard of not less than twenty (20) feet. The minimum distance between a building and the nearest residence district is twenty-five (25) feet. Other than access driveways and except as provided in § 70-192C, no side yards are required. The Project will comply with these requirements. Details will be provided in the final site plan.

§70-193 - Loading and unloading areas. States that provision shall be made on the premises for off-street loading and unloading in a location that will not interfere with accessory parking and means of ingress and egress thereto, and said areas shall be surfaced in the same manner as the parking areas. All open areas used for the storage of equipment or materials shall be at the rear of the premises and shall not encroach upon the off-street parking or loading areas and that there shall be no abandonment of any article upon the premises. The Project will comply with these requirements.

§70-194 - Fencing. Fences shall not exceed seven (7) feet in height. The converter station site boundary fence will not exceed 7 feet. However, the converter station will include sound walls of 8 and 16 feet, associated with various items of equipment, to mitigate noise. To the extent these sound walls are deemed to be fences within the meaning of this section, a waiver of this section is required. The visual impacts of the soundwalls will not be significant due to screening from vegetation and architectural treatments on sound walls. Detailed sound wall and screening plans will be included in the Environmental Management and Construction Plan (EM&CP) for the Duffy Road Converter Station.

§70-195 - Sewage disposal. States that all buildings used for manufacturing purposes not connected with a municipal sewerage system shall be equipped with an independent sewerage system and disposal facilities approved by the Nassau County Department of Health and/or Town of North Hempstead Building Department. The project does not involve manufacturing; therefore this chapter is not applicable.

§70-219 - Site Plan Review. Where a permit is otherwise required in relation to a site greater in size than one acre, and a new building larger than 750 square feet, site plan approval by the Town Board must be obtained. Section 70-219 sets forth the procedures and requirements. Neptune RTS• will meet the information requirements in the EM&CP preparation process and expects that the Town will be an active participant in EM&CP review for the converter station.

Chapter 7 of the Town of North Hempstead Code - Building Code Chapter 7 of the Town Code adopts and incorporates the New York State Uniform Fire Prevention and Building Code Act, Title 19 NYCRR Part 444.The design of the Duffy Avenue Converter Station will meet all applicable provisions of the Uniform Code.

Chapter 18 of the Town of North Hempstead Code - Excavations, Highway Chapter 18 of the Town code governs the excavation of.Highways. No excavation of Town highways is anticipated but in the event that highway excavation becomes necessary, excavation shall proceed according to the Town code.

Chapter 20A of the Town of North Hempstead Code - Environmental Planning and the Control of Trees Chapter 20A of the Town code governs tree removal. Activities on state owned lands are exempted from this chapter. Any tree removal will occur on state lands and therefore would be exempt from this chapter.

Chapter 25 of the Town of North Hempstead Code - Grading and Soil Removal Chapter 25 governs Grading and Soil Removal. Soil removal activities require a permit except when related to building or installation of utilities that are covered by other building permits. All soil removal and grading activity will be detailed in the EM&CP.

A specific provision prohibits the operation of any machinery, equipment, pump, fan, exhaust fan, attic fan, air-conditioning apparatus or similar mechanical device in such a manner as to create any noise exceeding fifty (50) decibels at the adjoining property line. (Town of North Hempstead 1968 §38-2(M). As demon- strated in Exhibit 4.13 of this supplement, the converter station operation will meet this requirement. Section 38-2 (F) - Certain Noises Prohibited states 'The erection, including excavating, demolition, alteration or repair, of any building other than between 7:00 a.m. and 6:00 p.m. on weekdays, except in cases of urgent necessity in the interest of public safety and then only with a permit from the Building Department, which permit may be renewed for a period of three (3) days or less while the emergency continues." As required construction of the converter station will be limited to the hours between 7:00 a.m. and 6:00 p.m. on weekdays, except in narrow circumstances required to complete a task and except for construction inside building walls.

7.2.4 Nassau County Comprehensive Master Plan The Nassau County Comprehensive Master Plan, adopted in September 1997, is a statement of community goals and policies concerning the development, protection, and revitalization of the county as a whole. The Master Plan forms the basis of the town ordinances in Nassau County that regulate land use and development. The Master Plan includes several observations and goals that are relevant to the development of the Duffy Road Converter Station. Among these is a prediction that the population of Nassau County will increase over the next several years, and that degradation of air quality is a primary concern. The project is consistent with the observations, opportunities, and goals presented in the Master Plan. The Neptune Project will provide additional energy resources to the area to serve the growing population. The Project will bring energy to the area without the concomitant air emissions associated with a traditional power plant. Once in operation, the converter station would generate no commuter traffic and very little delivery traffic, typically only a few vehicles a week.

E-1.1 System Overview This project involves the installation of high voltage transmission cables to transmit approximately 600 MW of power from the JCP&L/First Energy Substation in Sayreville, New Jer- sey to an existing LEPA substation at Newbridge Road, Long Island, New York. The project comprises an AC to DC converter station to be constructed at River Road in the Borough of Sayreville, New Jersey; a DC to AC converter station to be constructed at 508 Duffy Avenue in the Town of Hempstead, New York; 500 kV HVDC submarine and underground transmission cable system to transmit approximately 600 MW1 of power from the Sayreville Converter Station to the Duffy Avenue Converter Station; and underground AC cables to connect each converter station to their respective AC substation counterparts. This section describes the changes associated with the Duffy Avenue Converter Station site and upland cable route. The Sayreville to Newbridge Road route is approximately 67 miles. The majority of the Sayreville-Newbridge Road route (53 miles) is submerged, and the remainder (approximately 14 miles) is buried upland along the Jones Beach Causeway and Wantagh State Parkway between the Fishing Pier landfall and the converter station site and between the converter station site and the Newbridge Road Substation. The Duffy Avenue Converter Station will be located approximately 12.2 miles north of the landfall point near the Jones Beach State Park Fishing Piers. Ap- proximately 1.7 miles of this distance is north of the Newbridge Road Substation and traverses areas not discussed in the original application. The AC cable linking the converter station to the Newbridge Road Substation will be installed parallel to the HVDC cable along this portion of the route. Neptune RTS• will consist of the following major components within New York State:

• Underground and submarine High Voltage Direct Current (HVDC)/Integrated Return Conductor (IRC) cable to be installed from a converter station in Sayreville, New Jer- sey to the Duffy Avenue Converter Station, a distance of approximately 35.2 miles within New York State (23 miles in-water and 12.2 miles upland).

• A converter station constructed at 508 Duffy Avenue.

• Underground Alternating Current (AC) cable connecting the proposed Duffy Avenue Converter Station to the existing Newbridge Road Substation, a distance of approximately 1.7 miles.

The HVDC/ IRC cable and associated fiber optic cables will be as described in the original Application.

E-1.2ACCable Figure E-l-1 shows a typical cross-section of the proposed AC cable core used to connect the Duffy Avenue Converter Station to the Newbridge Road Substation. The cable consists of three cores that will typically be laid in close trefoil formation. In some areas, such as crossing under existing utilities, the cable may be laid in flat formation. The inner copper conductor is surrounded evenly with XLPE insulation and a lead metallic sheath to protect the cable during installation and to serve as a moisture seal. The metal moisture barrier can withstand flooding and groundwater and, in the event that the outer servings are damaged, the swellable tape will limit the longitudinal intrusion of water. Figure E-l-2 shows a HVDC/IRC cross section. An existing electrical one-line drawing of the Newbridge Road Substation is shown in Figure E-l-3a, and the proposed interconnection one line in Figure E-l-3b. The electrical one- line drawings for the Duffy Avenue Converter Station are included as Figures E-l-4 (1, 2 and 3).

This section describes the Duffy Avenue Converter Station.

E-2.1 Converter Station The HVDC portion of the Sayreville to Newbridge Road line would terminate at a converter station that will be constructed at 508 Duffy Avenue in the Town of North Hempstead, Long Island, New York. The Duffy Avenue Converter Station site will be leased from the State of New York. The area to be leased will be approximately 880 feet along the north boundary, approximately 1300 feet along the east boundary, approximately 320 feet along the south boundary and approximately 1340 feet along the west boundary. The DC cable would follow the Jones Beach Causeway and Wantagh State Parkway rights-of-way north for approximately 12.2 miles, as shown on Figure 2-3, to a point within the right-of-way west of the converter station, where it would turn east to the converter station. The 345kV AC interconnection from the converter station to the substation will travel west from the converter station to the Wantagh State Parkway ROW then proceed south, approximately 1,7 miles, along a route parallel to the DC cable. The route would terminate at the existing Newbridge Road Substation where it will connect to a 345/115kV transformer through a high side 345kV circuit breaker. Connection from the transformer to the existing 115kV substation bus will be designed by LIPA. Figure E-2-6 shows the Duffy Avenue Converter Station layout. Figure 2-10 shows the route of the DC and AC cables in the vicinity of the converter station. The following is a list of the major components of the Duffy Avenue Converter Station:

• Thyristor Converter Valves;

• Three (3) single-phase, two-winding oil-immersed transformers or six two winding (1/2 size transformers, plus a spare;

• Air core DC smoothing reactor that will be air-cooled and air-insulated;

• AC filter system to absorb the major part of the harmonic currents, which are produced by the converter, and to provide reactive compensation;

• Control and protection system for operation and monitoring of the station; and

02:001412_EA01_07_00-B1132 E-2-1 Exhibit E-2 Duffy.doc-05/27/03 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Exhibit E-2 - Other Facilities

• Other auxiliary systems, including AC auxiliary power, DC distribution, valve cooling system, ventilation system, and fire protection system.

E-2.2 Design and Installation Details The converter stations will be designed, manufactured, installed, and tested by Siemens AG. All structures will be constructed in accordance with the NYS Uniform Building and Fire Prevention Code. Foundations will consist of a combination of concrete slabs and driven piles as required, based on geophysical conditions and final design requirements. Detailed vendor descriptions were previously provided in response to DPS discovery questions. At the Duffy Avenue Converter Station, the central part of the converter station comprises a complex with four sections, the converter transformer bays, the valve hall, the DC equipment hall, and the adjacent control and auxiliary building. The HVDC cable is terminated inside the DC equipment hall. The indoor gas-insulated AC-switchgear (GIS) is installed in a separate building, opposite the transformer bays. The buildings will be of variable height with the tallest approximately 64 feet tall. Fenced outdoor sections with concrete foundations provide the space for AC filters, the shunt reactor and the converter transformers. The connection between the GIS and transformers are via a strung bus on gantries. The filters are connected to the GIS with conductors on support insulators. Other structures include:

• Housing for the water coolers of the valve cooling system;

• Air handling system housed in a pre-fabricated structure;

• Emergency generator and tank in a pre-fabricated structure;

• Fire-pump house; and

• Spare parts building.

Generally the buildings comprise reinforced concrete foundations and slabs with steel- framed structures with exterior metal insulated panels to walls and roof. A reinforced concrete wall separates the valve hall and transformer bays. Final design of the station foundation will be

02:001412_EA01_07_00-BU32 E-2-2 Exhibit E-2 Duffy.doc-06/27/03 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Exhibit E-2 - Other Facilities dependant on geotechnical investigations and will be specified in the final design included in the EM&CP. A reinforced concrete common oil and deluge containment tank is provided for the oil filled components (i.e., the converter transformers, including the spare unit and the shunt reactor). Access roads within the substation will be constructed with a crushed stone base and macadam finish. The converter station will be surrounded by a perimeter security fence approximately 7 feet high. Facilities will be secured by fencing during construction and operation. Lightning protection will be provided in the form of a combination of poles and overhead ground wires. Construction and site preparation activities at the site will include the following:

• Excavation and grading;

• Construction of foundations for the converter building, transformers, and switchgear; and

• Installation of appropriate drainage systems and station utility services including electric, water, and waste systems.

All power equipment will be factory-tested in accordance with applicable standards prior to shipment. The converter station control and protection system will designed, assembled, and tested by Siemens AG prior to installation to ensure proper operation and reduce on-site commissioning time.

E-2.3 Control and Protection The control and protection system of the HVDC transmission system will be designed, manufactured and tested by Siemens AG. Off-site tests of the control and protection systems will be performed prior to shipment to the construction site. Detailed vendor descriptions were previously provided in response to DPS discovery questions. The control system of an HVDC transmission installation is designed in redundant two- channel technology. The backup systems operate in hot standby mode to the channel that is active. An integrated rapid response switching logic selects the non-faulty channel

02:0OU12_EA01_07_0O-BU32 E-2-3 Exhibit E-2 Diiny.doc-06/27/03 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Exhibit E-2 - Other Facilities automatically. Failure of a control system component, faulty maintenance, or repair work in one system will therefore not impair transmission capacity. The division of the converter station into filter, transformer, valve, DC yard, and cable zones gives selective response and annunciation, for equipment failure. Each zone is monitored by at least two independent protection systems. The protection of the AC bus bars and the AC grid interconnection will be designed in accordance with NY ISO and LIPA design requirements. Also, an event recorder receives and records detailed information on fault events. This time-tagged information is stored and available for analysis. In addition to remote access of data from the event recorder, fault information can be retrieved locally from the protection device for on-site diagnosis, providing detailed knowledge about cause and effect.

E-2.4 Cooling Systems The converter valves generate heat during operation. The Siemens AG Thyristor cooling system is a single, closed-loop de-ionized water system. Dry coolers provide the heat transfer to the ambient air. The cooling system works independently of other cooling and air conditioning systems, and does not use glycol or other chemicals and additives. The cooling system consists of centrifugal pumps, ion exchangers, makeup water to add water to the main circuit, expansion tank, filters, and cooling equipment consisting of dry cooling coils and axial type fans. Redundancy is provided for all critical parts to provide high reliability and allow for maintenance during operation.

E-2.5 Station Service In order to ensure full supply and delivery of power even at full load or emergency situations, redundant systems will be installed. Automatic switchover logic will be provided to ensure that the interruption of one AC supply feeder will not lead to an interruption of the HVDC power transmission. All equipment for control and protection is supplied along with the DC systems. The DC distribution systems provided in each converter station will be fed by independent 220 V and 48 V batteries and chargers. The cooling pumps for the valves will also be supplied by an independent uninterruptible power supply (UPS) system consisting of a separate battery charger, storage battery, and static inverter.

Underground Construction

02:001412_EA01_07_00-B1132 Exhibit E-3 Duffy.doc-06/27/03 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Exhibit E-3 - Underground Construction

This section describes underground construction in upland portions of Long Island. The upland route will include the DC cable, from the upland side of the Long Island landfall north to the Duffy Avenue Converter Station, and the AC cable from the Duffy Avenue Converter Station south to the Newbridge Road Substation.

E-3.1 Cable System Installation Cable routes and installation technologies were selected to minimize environmental impacts. The underground HVDC cable and AC cable lines would be installed in an upland area between the Long Island landfall and the Newbridge Road Substation. Both HVDC and HVAC cable lines would be installed in parallel trench systems for an approximately 1.7 mile section of the route, between the Duffy Avenue Converter Station and the Newbridge Road Substation. The cable will make landfall on the eastern side of the Jones Beach Causeway near the Fishing Pier at Jones Beach State Park (see Figure 2-8). Landfall will be made utilizing horizontal directional drilling technology to minimize disturbances to tidal wetlands and the shoreline.

DC Cable Installation DC cable will be installed for a distance of approximately 12.2 miles from the landfall point to the Duffy Avenue Converter Station. The cable will run north along the east side of the Jones Beach Causeway and Wantagh State Parkway within the ROW. DC cable would be installed by using a combination of cut-and-cover, horizontal directional drilling and hydraulic jack techniques as appropriate to minimize impacts. Directional drilling will be used where necessary to avoid impacts to regulated freshwater and tidal wetlands, and where the route traverses roadways, entrance and exit ramps, and railroad crossings. (Additional information on wetland protection and mitigation requirements is presented in Section 4.7.) Horizontal directional drill entry pits will typically be 10 feet by 10 feet within a staging area of approximately 5,500 square feet, and exit pits will typically be 10 feet by 20 feet. Larger exit pits may be required in some areas to ensure control of drilling fluids. Exit and entry pit details will be included in the EM&CP. The actual drilling will be performed by means of a guided boring, followed by reaming operations to achieve the desired dimension (16- to 24-inch diameter) to allow pulling in an up to 14-inch PE pipe. Figure E-3-9 shows a typical

02:001412_EA01_07_00-B1132 E-3-1 Exhibit E-3 Diiffy.doc-06/27/03 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Exhibit E-3 - Underground Construction

cross section of the HDD bore holes. As the drilling operation nears completion and the drill emerges within the ROW, the high density polyethylene (HDPE) is plugged and marked to await the installation of cable later in the construction process. The entry point of the conduit will also be plugged to await installation of the cable. Once the cable is installed, clay/bentonite will be . used to fill the void space between the conduit and cable. The clay-bentonite medium is typically used because of thermal rating considerations. Completion of each directional drill is expected in 1 to 3 days. Information on control of drilling fluids has previously been provided in response to Discovery Request DEC-22. The cable will be installed beneath the Merrick Road on-ramp using hydraulic jack technology. Installation using hydraulic jack technology will require one pit on each side of the on- ramp to install a casing with a hydraulic jack, through which the cable will be pulled. In cut-and-cover construction, a single trench approximately 3.5 feet wide and a minimum of 5 feet deep would be excavated, and the cable system would be buried to a typical depth of 4 feet and to a minimum depth of 3 feet to the top of cable. Figure E-3-7 shows a typical cross-section of the DC upland cable installation. Use of conduit along any portion of the route, including major crossings, would be pre-installed for easy initial installation. All excavation would be performed using standard construction methods and equipment and in accordance with local, state, or federal safety standards. Excavated soil will be temporar- ily stockpiled next to the trench. Storm water erosion and sedimentation controls will be installed on site prior to initiation of construction activities. The cable system will be embedded in a minimum 24-inch fill layer with appropriate thermal characteristics. A concrete top (minimum 3 inches) will also be placed above the bedding layer to provide additional protection of the cable. The remainder of the trench will be backfilled with native excavated soil. Any excess soil will either be reused on site or disposed of off-site. Once construction is completed, excavated areas will be restored to their original condition.

AC Cable Installation The AC cable will be installed within the ROW along the east side of the Wantagh State Parkway, parallel to the DC cable, between the Duffy Avenue Converter Station and the New-

02:001412.EA01_07_00-B1I32 E-3-2 Exhibit E-3 Duffy.doc-06/27/03 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Exhibit E-3 - Underground Construction bridge Road Substation, a distance of approximately 1.7 miles. Cross sections for various methods for AC cable installation are shown in Figure E-3-8. The AC and DC cables will be installed in separate parallel trench systems with a minimum distance of 15 foot center-line to center-line, as depicted in Figure E-3-10. Directional drilling or hydraulic jacking will be used where necessary for installation where the route traverses roadways, entrance and exit ramps, and railroad crossings. The exact length of the each directional drill would be determined once the final exit points within the ROW have been determined. Where directional drilling is necessary for the AC cable, a pipe with diameter of ID 24 inches to 30 inches will be required to accommodate the strap of three cables each in a separate pipe bundled together. The required dimension of the bore, including reaming, may range from 30 inches up to 36 inches. Wherever possible, the AC cable will be installed in a single trench as described in the original application and depicted in Figure E-3-8. For the majority of the route the cables will be placed in trefoil formation. As with the DC cable, major crossings will be made by pre-installed conduit and may be installed in flat formation. Temporary shored excavations will be used to accommodate splicing during installation and will be spaced approximately one every 800 meters. The excavations will be dewatered, as necessary during construction, using good engineering practices and as described in the EM&CP. The excavations will be temporary and once construction is complete they will be backfilled and capped with concrete. Therefore, there will be no potential for flooding once construction is complete. Figure E-3-11 depicts a typical temporary AC cable joint pit. Any permanent access manholes that may be required will be described in the EM&CP along with measures required to prevent flooding.

Clearing of Vegetation For the majority of the route between landfall and the Newbridge Road Substation, installation will occur within the maintained area adjacent to the Jones Beach Causeway and Wantagh State Parkway with minimal impacts to surrounding vegetation. In some areas trimming or tying of overhead vegetation will be required in order to safely operate machinery, but this will not re-

02;001412_EA01_07_00-B1132 E-3-3 Exhibit E-3 Dufiy.doe-06/27/03 Neptune Regional Transmission System LLC Article VII Application Second Supplement June 2003 Exhibit E-3 - Underground Construction quire the removal of vegetation. In other areas where removal of vegetation is required, it will be restored in accordance with the EM&CP. Areas that require or may require clearing are described below. Installation of the DC cable within the Jones Beach Causeway, from the landfall point near the Fishing Piers to the southern terminus of the Wantagh State Parkway, may require the removal of shrub growth east of the bike path in order to offset the project from existing utilities along the Causeway. The location and extent of any clearing is dependant on the location of existing utilities, which are not yet known, and the separation required to protect existing and proposed facilities. Interested agencies will be consulted with regard to any required clearing and the location, extent and species to be cleared will be specified in the EM&CP. Clearing will be required for the directional drill exit pit at Merrick Road. The affected tree layer may include a sugar maple {Acer saccharum) and black locust (Robinia pseudoacacia) approximately 30 feet tall. The shrub layer includes black cherry and staghom sumac {Rhus ty- phina). Once installation is complete, the vegetation will be restored with species native to Long Island. Details will be included in the EM&CP. Installation of the parallel AC and DC cables between the Duffy Avenue Converter Sta- tion and Newbridge Road Substation may require the removal of minimal shrub growth within the ROW to accommodate parallel installation of the cables and installation from the ROW to the converter station may require removal of shrubs and trees. The location, extent and species to be cleared will be specified in the EM&CP. Installation of the AC cable between the Wantagh State Parkway and the Newbridge Road substation will require clearing a path approximately 15 to 20 feet wide and 80 feet long. The trees affected include one live black cherry (Prunus serotina) tree approximately 25 feet tall and one dead black cherry tree. The shrub layer includes hawthorn (Crataegus sp.), hoptree (Ptelea trifoliata), and Tartarian honeysuckle (Lonicera tatarica). The herb layer is dominated by poison ivy (Toxicodendron radicans) and largely suppressed by vines of poison ivy and Japa- nese honeysuckle {Lonicera japonica). Clearing in this area will be minimized by using an entry point that is relatively clear of woody vegetation due to the dominance of a large dead tree.

Permanent Route Markers The DC and AC cable routes will be marked with route markers to identify the as-built location of the cable. The markers will be 66 inches tall and 3.8 inches wide and will be buried 24 inches in the ground. A sticker will be attached to each marker that identifies the owner, type of utility, and a contact number. The markers will be flexible enough to return to original posi- tion if run over in the course of mowing. The markers will typically be placed every 300 to 500 feet along the route and at substantial bends, underpasses, and crossings. Markers will be placed at the beginning and end of each bend such that each marker can be viewed from the previous one. Figure E-3-12 depicts a typical warning marker. The design of the marker will be chosen in consultation with OPRHP.

E-3.2 Cable System Reliability Upland cables will either be direct buried or installed in conduit to a minimum depth of 3 feet below ground surface with a concrete top layer installed above the cable/conduit system. During cut-and-cover construction, a single trench approximately 3.5 feet wide and a minimum of 5 feet deep would be excavated, and the cable system would be buried to a target depth of 4 feet to the top of cable or at least to a minimum depth of 3 feet to the top of the cable/conduit. This type of installation will provide sufficient protection, for both AC and DC cables, against damage due to traffic or unauthorized or misdirected excavation. At all utility crossings, the cable will be protected by a preinstalled polypipe or similar covering offering adequate mechanical protection. The AC cable design includes a metal moisture barrier of lead alloy that can withstand flooding and groundwater. In the event that the outer sleeves are damaged, a swellable tape will limit the longitudinal intrusion of water.

E-3.3 Cable System Maintenance Once installed, the cables are not expected to require routine maintenance. A fiber optic cable will be either strapped to the cable, or installed along side, and used for terminal to terminal communication and to monitor the performance of the HVDC system, including the cable. Both the AC and HVDC cables are designed to prevent the release of any polluting materials into the environment, even if left unrepaired for a substantial length of time, in case of damages

caused by internal (e.g., electrical fault) or external causes. In the unlikely event the cable is damaged, the procedures for an emergency repair of the cable presented in the original Applica- tion will be followed.
