Marcy Nanocenter
Preliminary Study Report
1. Background
In accordance with Mohawk Valley Edge’s request, National Grid hereby submits this
Preliminary Study Report- Alternative#2 for the Marcy Nanocenter115kV line
relocation.
o This study was performed under a support services agreement between Mohawk
Valley Edge and National Grid.
o This study determined the cost and schedule to relocate the 115kV Porter -
Terminal #6 Line as close as possible to the existing Oneida - Porter #7 /
Yahnundasis - Porter #3 ROW and the edge of the Marcy Nanocenter property.
This approach maximizes the property available for development of the Marcy
Nanocenter site.
Note: This report provides an alternate approach (as requested by MVE) to the original
Preliminary Study Report dated November, 2009.
2. Executive Summary
National Grid has determined the following:
o The Porter - Terminal #6 Line that runs through the Marcy Nanocenter site can
be re-located to run along the existing ROW for the Oneida - Porter #7 and the Yahnundasis - Porter #3 Lines. With current information known, there does not appear to be any difficulties in doing this work.
o No special line outages will be required to move the circuits, other than those
outages required to do line cutovers to existing energized circuits.
o Permitting and regulatory work will be required prior to construction. These
requirements are not un-common or necessarily difficult to do, but do impact the project schedule and must be planned for.
o National Grid is willing to work with Mohawk Valley Edge (MVE) to accommodate
this move from a right of way perspective. This assumes that MVE is willing to provide new right-of-way properties, as outlined below, to accommodate the relocated line. In like fashion, National Grid will surrender the existing Porter -
Terminal #6 right-of-way property. Note that with these adjustments, MVE must still deal with fiber optic cables (Verizon and Elantic) that currently follow the existing transmission lines and traverse the property.
o Environmental assessments performed under the November study, did not
produce any particularly unusual challenges from the information gathered. It is
anticipated that this will remain this way and that no significant wetlands,
archeological, endangered species or other concerns will be encountered on this
project. This must be verified with additional analysis (delineation, involvement
of agencies, etc).
o Electric and Magnetic field simulations show that future line relocation will be
below PSC established limits at the edges of the right-of-way.
o Schedule for doing this work is 27 months from contract agreements between
NG and MVE. Approximately 8 months of this schedule are associated with the necessary permitting and regulatory approvals. Note that there may be opportunities to improve upon this schedule (no permitting/regulatory problems encountered, running key activities in parallel, etc).
o Cost for doing this work is estimated at $5,220,000 (in 2009 dollars). As with the
schedule, this is a conservative estimate that may be improved upon as more detailed engineering and analysis is performed.

3. Project Objectives
The main objective of the project is to relocate the existing 115kV Porter - Terminal #6
Line which is located on Marcy Nanocenter’s property so that the property can be
developed.
The Porter - Terminal #6 Line is to be relocated along the existing Oneida - Porter #7
and Yahnundasis - Porter #3 ROW. The ROW may need to be expanded to provide
enough spacing between the lines.
A new 100’ ROW will need to be developed at the western edge of the Marcy
Nanocenter site and the Porter - Terminal #6 Line will continue for about 3/4 of a mile
before reconnecting into the existing line.
New structures will conform to National Grid Standards. Conductors and shieldwires are
to be consistent with National Grid standards.
Run an EMF check on the proposed spacing to make sure it meets code and does not
exceed reasonable levels.
Perform a right of way and environmental assessment of site conditions with focus on
relocation of the NG lines.
Provide a site service evaluation on how best to serve the Marcy Nanocenter site.
o A cost estimate for this work will be created in a separate report, if requested by
the developer.
4. Existing Conditions
The 115kV line to be relocated is Porter - Terminal #6. In the section to be relocated,
Porter- Terminal#6 is currently supported by fourteen single circuit wood pole
structures, eleven suspension and three deadend, as shown in the table below. The
length of the section to be removed is about 1 mile.
Structure TypesNumber
Single Circuit 2-Pole Suspension Wood H-Frame Structure11
Single Circuit 3-Pole Deadend Wood Pole Structure3
Total14
Existing Conductor Information
Conductor795kcm ACSR “Drake”
5. Proposed Arrangement
The first mile of the relocated 115kV Porter - Terminal #6 Line will be within a shared
150’ ROW, with 50’ between the two structures.
The Porter - Terminal #6 Line will continue for another 3/4 mile in a 100’ ROW, before
reconnecting into the existing line. The new segment is to be supported by thirteen
single circuit, wood pole suspension structures with davit arms, and six single circuit,

steel pole deadend structures. The relocated segment of the Porter - Terminal #6 will span a total of 1 3/4 miles before connecting back into the existing line.
6. Scope of Work
Relocate the existing 115kV Porter - Terminal #6 Line into new ROW to run alongside
the Oneida - Porter #7 and Yahnundasis - Porter #3 Lines. The line relocation will be
with the addition of nineteen new single circuit, single pole structures.
Install new 795kcm ACSR “Drake” conductor and new 3/8” EHS shieldwire.
Remove the existing fourteen structures running through the Marcy Nanocenter
property.

8. Safety Assessment
Design and construction of this project should be performed in accordance with
applicable codes, regulations, bylaws and National Grid Standards. Construction of this
project will require work to be performed in close proximity to energized 115kV lines
during cutovers.
The absence of any safety issues, not cited herein, does not exclude them from
possibility.
9. Environmental Analysis
A preliminary environmental analysis was performed during the site visits to the MVE
site. In addition, National Wetlands Inventory (NWI) and New York State Department of
Environmental Conservation (NYSDEC) databases were assessed to determine
potential issues that may be encountered due to project impacts to regulated wetlands and protected streams. Field delineations of wetlands were not made.
Based upon a review of these databases and the visual analysis performed, there are no
NYSDEC-regulated wetlands or protected streams that will be impacted by the project.
There is one unregulated stream within the southern portion of the project site that will
be crossed by the relocated Porter-Terminal #6 Line, but this should not be an issue.
Federal wetlands within the project area are mapped but these maps are not available
from online information sources. During the more extensive data gathering phase of the
project that will be required to support the licensing and permitting filings for the project,

Marcy Nanocenter
Preliminary Study Report
a right-of-way walkdown will be required to identify federal wetlands, if any, that may be impacted by the project.
10. Environmental Regulatory Licensing and Agency Review Requirements
Part 102 Report
o Pursuant to New York State Public Service Commission (NYSPSC) utility regulatory
requirements established in Title 16 of the Public Service Law, Part 102 - Installation
of Non-Article VII Electric Transmission Facilities, any utility proposing to construct
115 kV transmission facilities one mile or longer but less than ten miles in length
must report the proposed construction to the NYSPSC at least 60 days before the
proposed commencement of construction. The purpose of this reporting requirement
is to afford the agency an opportunity to review the project to determine whether the
transmission facility may be placed overhead or whether all or a portion of the facility
should be placed underground. The “Part 102 Report” is also used to provide
evidence to the commission that NG has considered and addressed key
environmental and outreach areas and that the Company has complied with all
applicable local, state and federal laws.
oAreas that are typically addressed in the Part 102 filing include, but are not limited to:
Project Description and Need
Justification for Overhead Construction Community Outreach Activities
Environmental Issues/Impacts and Agency Consultation (New York State Office of Parks, Recreation and Historic Preservation; NYSDEC; US Fish & Wildlife Service; New York Natural Heritage Program; NYS Department of Agriculture and Markets
Project Aesthetics - potential requirement for a visual/view shed analysis
o The Part 102 report is typically prepared by an environmental consultant under
contract to NG’s Environmental Department. Gathering of information and report
preparation and filing are usually completed in 4-6 months. The NYSPSC review
process is typically completed within 2-4 months following the filing of the report.
New York State Office of Parks, Recreation and Historic Preservation (OPRHP)
o Preliminary review of this project against OPRHP’s online database indicates that the
project will not impact any state or federal listed resources or resources eligible for
such listing. However, the project area is within a mapped Archaeological Sensitive
Area and consultation with OPRHP is recommended. Such consultation could result
in a requirement to complete an archaeological and cultural resource survey of the
project area (3-4 months to complete the report, submit to OPRHP, and obtain
OPRHP response).
Stormwater Pollution Prevention Plan (SWPPP)
o Total site disturbance associated with the relocated transmission line, transmission
line removals, and related activities will exceed the one acre threshold which triggers
the requirements of NYSDEC’s SWPPP program. Therefore, a SWPPP must be
prepared for this project and construction cannot begin until the SWPPP has been
completed, a Notice of Intent (NOI) form filed with the NYSDEC, and a SWPPP
acknowledgment letter received from the agency. The SWPPP program will also

Marcy Nanocenter
Preliminary Study Report
require a pre-construction site inspection, weekly inspections over the duration of the construction period, a post-construction inspection and the filing of a Notice of Termination (NOT) form upon completion of construction and site restoration and stabilization. The SWPPP, NOI filing, and receipt of NYSDEC coverage letter typically can be completed within 3-4 months.
NYSDEC Permits
o As noted above, there do not appear to be any NYSDEC-regulated resources
impacted by the project, so NYSDEC permits for the project are not believed to be
required.
US Army Corps of Engineers (ACOE)
o Although the extent of the project impact on federal wetlands is not currently known,
such impacts, if any, will be identified during the information gathering that is
required to prepare the Part 102 report and the SWPPP. Typically, such impacts are
small and project impacts would be tailored in accordance with NG’s environmental
guidance procedures (i.e. use of appropriate erosion and sediment controls, no
permanent fill in wetlands, use of swamp mats or other suitable temporary methods
to cross wetlands, restoration of disturbed areas to pre-construction conditions, etc.)
so as to avoid ACOE permitting requirements.
Other Agencies
o Other environmental agencies including the NYS Department of Agriculture and
Markets, the NYSDEC’s New York Natural Heritage Program, and the US Fish &
Wildlife Service may be contacted to determine, respectively, whether the project
may impact sensitive agricultural areas and state- or federal-listed threatened or
endangered species. Although these agencies do not have specific permitting
authority, evidence of agency consultation is required as part of the NYSPSC and
ACOE review and SWPPP preparation process. If project-related impacts are
identified, appropriate measures will be incorporated into the project design and
construction to mitigate the identified impacts.
11. EMF
Electric and magnetic field levels were calculated at the New York state standard height
of one meter above ground level at the edge of right of way, using the PLS-CADD EMF
calculator. These calculations are based upon EPRI “red book” methods.
All calculations were based upon winter normal loading conditions (1500 amps Drake
conductor)
For the line configuration modeled (graphs shown in the appendix of this report) both the
electric and magnetic field are below the NYS PSC edge of right of way requirements of
1.6 kV/m (electric) and 200 mG (magnetic).
As can be seen by looking at the graph, the EMF values continue to “trail off” past the
edge of the right of way. These low values will be key to attracting chip fabrication
industry to this site.

Marcy Nanocenter
Preliminary Study Report
12. Local Permitting
No formal assessment has been done. As a part of any construction on any site, local
permitting requirements must be adhered to. Specific zoning requirements and local
building codes may control design and construction on the site. Due to the fact that
transmission structures are all ready present on the site, this is not for-seen as a
problem; however local requirements must be investigated and may come into play.
13. Right of Way
The right-of-way work for the Marcy Site falls into two categories. That right-of-way that
will need to be widened to relocate the existing 115kV Porter - Terminal #6 Line and the 100’ right-of-way that will be developed to the west side of the Marcy Site (Marcy Site Relocation Right-of-Way). New right-of-way will also be required for two new 115kV lines that are needed to provide dual service to the customer owned station (Marcy Site New Service Right-of-Way).
Marcy Site Relocation Right-of-Way
o To accommodate the proposed 115kV relocations a combination of fee and easement
right-of-way must be conveyed to Niagara Mohawk Power Corporation (NG) in order to
replace ‘like with like” property rights. Currently the double circuit Oneida-Porter #7 /
Yahnundasis-Porter #3 Line (#7/#3 Line) occupies a 100 foot wide fee owned right-of-
way (Tax Parcel 293-1-80, Town of Marcy) and the single circuit Porter-Terminal #6 Line
occupies a 100 foot wide easement. A fee strip will be required for only that portion of
the relocation that includes the #7/#3 Line as shown on attached Exhibit SUP-A. It will
be necessary for the new fee strip to expand the existing ROW to 150 feet in width since
the right-of-way for this portion of the relocation must accommodate the existing 115 kV
double circuit and single circuit structures (see attached cross sections). As shown on
Exhibit SUP-A, the remaining portion of the relocation right-of-way will be a 100 foot
wide easement strip which will accommodate one single circuit structure. Both
instruments (deeds and easements) will be required to have additional language to
cover “guying rights” and “danger tree rights” outside the primary strip. It is noted that
there are two alternatives shown for the easement portion of the right-of-way. The
shorter alternative “B” is located entirely on the Marcy Site while the longer alternative
“A” would leave the Marcy Site and traverse private property to the south. The shorter
“B” alternative was shown in the event that MARCY NANOCENTER decides not to
attempt to acquire easement rights from private landowners. The longer “A” alternative
was the route used for purposes of the cost estimate.
o For the purposes of this report, it is assumed that MVE will acquire all fee parcels and
easements and convey all fee parcels and easements to NG at no cost. NG
administrative, legal and closing costs are included in the estimated cost. National Grid
will release any portions of the existing easements across MVE property that are no
longer necessary as a result of the relocations. NG will retain title of the existing 100 foot
wide fee strip unless MARCY NANOCENTER arranges to have the two buried fiber optic
cables (Elantic and Verizon) that currently occupy the existing fee strip moved to the
new fee strip.

Preliminary Study Report
Marcy Site New Service Right-of-Way
As noted in the site service study section of this report, two alternatives have been
considered to provide dual 115kV service to the Marcy Site. Both alternatives require
obtaining right-of-way from private landowners along the entire length of the respective
routes. The right-of-way requirements for either of the alternatives, and for any other
alternatives that might be considered in the future, will be a 100 foot wide easement in
locations where one line occupies the right-of-way and a 150 foot wide easement in
locations where two lines occupy the right-of-way. The easement instruments will be
required to have additional language to cover “guying rights” and “danger tree rights”
outside the primary strip. If MVE determines to select either of these alternatives, it is
assumed that MVE will procure all necessary easement rights as required by NG and
convey those rights to NG at no cost.

Preliminary Study Report
14. Site Service Study
Study Overview
o National Grid has undertaken a preliminary planning review of likely alternatives to
provide redundant 115kV service to a 50 MVA load at the Marcy Site. This work will be additional and is not included in the cost estimate. To provide this redundant service, two separate pathways would be required, including separate structures, to avoid the potential for a single failure removing both services simultaneously. National Grid has identified three likely alternatives, which are outlined as follows:
Option 1:
o Option 1 includes two single 115 kV line taps, originating at Porter Substation, which
would serve just the Marcy Site. An individual breaker would serve each line at Porter. Each line would be a dedicated feed to the project site. It is anticipated that this solution would require new RIGHT-of-Way (ROW) and new structures between Porter and the Marcy Site for one of the lines; and for the second line, removal of the existing PorterTerminal H-frame structures, and replacement with a double circuit towers. All this would have to be accomplished in an area already congested with existing ROW and limited egress. An investigation into potential availability of property for new ROW would have to be conducted before this option could be selected.
Option 2:
o Option 2 has one single line tap at a breaker position originating at Porter Substation,
similar to those proposed in Option 1, plus an additional tap from the (to be relocated) 115kV Porter-Terminal transmission circuit. This would again provide two separate and independent services. There would still be a need to install new towers for the Porter tap, plus an additional single breaker station will be needed at the Marcy Site to handle the additional line tap. This option may require new ROW as in Option 1.
Option 3:
o Option 3 would split the existing Porter-Terminal 115kV line into two parts, there by
making one line into two and providing redundant service from two directions. A new
station with a 3 breaker ring configuration would be constructed on the Marcy Site at the
split point. With this configuration, one end of the line can be out of service, while other
would still remain to serve the Nanocenter. With Option 3 most, if not all, work would be
located on the Marcy Site, and not involve other existing ROW or outside property
owners.
Recommendation:
o It is National Grid’s current recommendation that Option 3 to pursued. Since the work is
primarily limited to the Marcy Site, this provides for better project transparency and control. And this avoids the potential property/political issues associated with ROW expansion and/or expansion on our existing ROW.
Disclaimer:
oThe cost estimate included in this Preliminary Study Report is for the Porter - Terminal
#6 Line relocation only.
oA cost estimate for completing this Nanocenter Site Service will be completed in a
separate report if requested by Marcy Edge.

Preliminary Study Report
15. Cost Estimate
The following represents National Grid estimate to do the following work:
o Relocate the existing Porter - Terminal #6 Line between structure number 12 and
26. The new segment is to be supported by nineteen single circuit structures. Six
single steel pole deadend structures and thirteen wood pole suspensions
structures will run parallel to the Oneida - Porter #7 and Yahnundasis - Porter #3
Lines on an expanded ROW. The ROW will have to be widened to provide
enough spacing between lines. The Porter - Terminal #6 Line will continue by
itself for another 3/4 mile on a 100 foot ROW, before reconnecting into the
existing line.
Estimate assumptions:
oNo right-of-way “real property” cost. Lands will be transferred between National
Grid and Marcy Nanocenter for consideration of 1 dollar. Costs are included for
labor associated with land transfers, closing costs and legal costs.
oAll cost estimates in 2009 dollars. No escalation included.
oAllowance for funds used during construction(AFUDC) charges are NOT
included in these costs, because NG is assuming that upfront payments will be
made by MVE. AFUDC charges represent interest on monies that National Grid
“borrows” to fund our projects and represent a relatively large amount of the total
amount. Accordingly to avoid these charges, prompt payments must be made by
MVE to NG.
oIt is assumed that the Marcy Nanocenter project is tax exempt.
oProject costs estimates are conceptual in nature. It is likely that this amount can
be reduced further with more detailed engineering, site investigation, wetland
delineation, permitting etc is performed.
oLines will be worked on concurrently, except during cutovers.
oNo environmental cleanup will be required.
oEstimates assume that a filing is required under NYS PSC Part 102. Costs for
this filing are included in the estimate.
oNo special local permitting required (i.e. zoning variance, subdivisions, etc).
Costs are included to attend local planning board meetings with towns.(2
meetings)
oThis estimate is based on the project taking 27 months from start of preliminary
engineering until final closeout.
oSite Service Study will be a separate project, and is not included in this estimate.
