D. Evaluation of Culverts

There are several culverts located along the proposed regional haul routes andlocal delivery routes that could be impacted by the OS/OW vehicles. GPI

transportation engineers met with representatives from NYSDOT, Jefferson

County and the Town of Cape Vincent to discuss the haul routes and localdelivery routes along roadways under their jurisdiction. The routes chosen were

selected to avoid traveling across bridges/culverts that have posted or known

weight restriction. Jefferson County provided GPI with culvert and bridge

inspection reports for many of the county and town roads expected to be used

during construction in the Town of Cape Vincent. The reports indicated that 2culverts and 1 bridge have visual signs of deterioration and are noted as follows:

A culvert located on County Route 4 (approximately 160 ft west of County Route8) shows deterioration on the headwall and wingwall.

A culvert located on County Route 8 (approximately 1000 ft south of MacombSettlement Road) shows moderate spalling on the headwall and wingwall.

A bridge located on Hell Street (approximately 3700 ft north of County Route 4)shows galvanized coating deterioration below the spring lines.

The culvert located on County Route 4 (approximately 160 ft west of County

Route 8) is the only location along a regional haul route or local delivery route.This culvert should be investigated further prior to construction to determine if

adequate capacity exists or if replacement should be considered. If replacement isnot considered feasible, alternate routes which avoid the suspect culvert should beestablished for delivery of the OS/OW equipment. The other culvert and bridge

listed is provided for informational purposes only and is not expected to be used

for the transport of OS/OW components during construction.

E. Evaluation of Bridges

Improvements to bridges along the proposed regional haul routes and localdelivery routes are not expected to be required. NYSDOT provided input on

established OS/OW haul routes which avoid bridges along state highways that

have size or weight restrictions. Jefferson County and the Town of Cape Vincent

provided input on posted or restricted bridges along their roadways within the



F. Potential Additional Evaluations

The improvements required to facilitate construction of the project will likelygenerate the need for additional studies and permits. Additional studies could

include:

Pavement Evaluation – a pavement evaluation could be used to determinethe condition of the existing roadways by establishing a baseline for

measuring impacts caused during construction.

Culvert Evaluation – a culvert evaluation could be performed to determine

the existing condition of culverts and ensure the safety of OS/OW loadstraveling over the culverts.

Bridge Evaluation – a bridge evaluation could be performed to determine

the existing condition of bridges and ensure the safety of OS/OW loads

traveling over the bridges.

G. Permits Required

The required improvements including intersection widening, extending culvertsand transporting OS/OW loads will require various permits. Permits from

NYSDOT, Jefferson County and the Town of Cape Vincent will be required to

complete the improvements and transport the components. Permits which will be

required are as follows:

Environmental Permits – site specific analyses of environmentalconditions will determine the need for permits at a particular location. Dueto the nature of the area, it’s anticipated the wetland permits will be

required at several locations.

Highway Work Permit – a highway work permit will be required for intersection improvements and proposed entrances to State, County andLocal roadways.

Special Hauling Permits – special hauling permits will be required for transporting the OS/OW components to the project area. Permits will be

required from NYSDOT and Jefferson County.



8.0 PRE-CONSTRUCTION CONDITIONS

A. Pre-Construction Road Conditions

On November 17-18, 2008, two GPI transportation engineers performed a cursoryvisual inspection of the proposed haul routes and roadway network. Their

inspection included identifying any restrictions that would be encountered along

the haul routes, more specifically identifying any overhead utilities or

obstructions, identifying any intersections which may require modifications or improvements and observing the general pavement and drainage conditions of the

roadways along the haul routes.

All of the NYS Highways including NYS Routes 3, 12, 12E, 12F, 13, 37, 104,

104B, 180 and 342 were all constructed using asphalt pavement. The shoulder

widths along these highways vary from 4 - 10 feet while the pavement widthvaries from 20 - 24 feet. The asphalt pavement was in fair to good condition

according to the 2006 NYSDOT Highway Sufficiency Ratings. A fair rating

indicates that pavement distress is clearly visible whereas a good rating indicates

that distress symptoms are beginning to show. The visual inspection performed byGPI confirmed that some of the routes show pavement distress beginning, usually

in the form of surface cracking. The NYS highways mentioned in this analysis

have been maintained as most of the cracking observed had been sealed to preventfurther degradation.

The Jefferson County Highways expected to be used during construction are

County Routes (CR) 4, 8 and 9. CR 9 consists of two 10-foot wide travel lanesand 3-foot wide gravel shoulders. Field observations noted the asphalt pavement

was in fair to good condition. Some longitudinal alligator cracking was noted

which had been recently sealed. CR 8 consists of two 10-foot wide travel lanesand 4-foot wide gravel shoulders which appeared to be in good condition. CR 4

consists of a 20-foot pavement width for two-way travel with no shoulders and

was in poor condition with visible potholes and structural problems. It appearedthat a recent micro overlay of the asphalt pavement has been performed, however

the structural problems were still clearly evident. The county roads are expected

to be utilized as part of the haul routes for the OS/OW materials which could

result in structural damage to county roads which already show significant signsof deterioration.



vehicles and an increase in volume caused by construction vehicles. The town

roads expected to be used during development were constructed with asphalt

pavement, although some sections of Hell Street, Wilson Road and MerchantRoad were constructed with crushed gravel. Many of the town roads are

approximately 18 feet wide with 5-foot wide shoulders for two-way traffic.

B. Pre-Construction Culvert Conditions

There are several culverts located along the proposed regional haul routes and

local delivery routes. GPI transportation engineers met with representatives fromNYSDOT to discuss possible regional haul routes to the project area. The routes

ultimately selected avoided culverts/bridges with weight restrictions.

A GPI transportation engineer met with representatives from Jefferson Countyand the Town of Cape Vincent to discuss the regional haul routes and local

delivery routes along roadways under their jurisdiction. The routes chosen were

selected to avoid traveling across bridges/culverts that have posted or known

weight restrictions. Jefferson County provided GPI with culvert and bridgeinspection reports for many of the county and town roads expected to be used

during construction in the Town of Cape Vincent. The reports indicated that 2

culverts and 1 bridge have visual signs of deterioration. Only the culvert locatedon County Route 4 (approximately 160 ft west of County Route 8) will be utilized

under the recommended haul or delivery routes. This culvert should be

investigated further prior to construction to determine if adequate capacity existsor if replacement should be considered.

C. Pre-Construction Bridge Conditions

The proposed regional haul routes include a number of bridges which the OS/OW

loads will travel over. Regional haul routes were selected to avoid traveling over

bridges which have capacity or clearance restrictions. No impacts are expected for

the bridges located along the regional haul routes.

Local delivery routes were selected to avoid traversing bridges which have

capacity or clearance restrictions. There is a bridge located along County Route 4approximately 1,700 feet east of Wilson Road which is posted for 18 tons. The

local delivery routes recommended in this study avoid the restricted bridge and



9.0 SCHEDULING OF DELIVERIES

There are several considerations which must be taken into account when planning

the schedule of deliveries to the project area as local travel patterns are subject toseasonal influences. During the winter months, severe weather conditions can

limit road access, as well as functional road width. During the summer months,

the region experiences a significant increase in tourism-related traffic. In addition,

commuting traffic and school bus schedules should be considered to avoidpotential impacts to these time-sensitive motorists.

It is expected that construction activities related to the project will coincide withthe peak seasonal travel and some overlap with the school year is anticipated.

Early strategic planning will be required to minimize the disruptions to motorists.

To the maximum extent feasible, BP Wind Energy should construct roadway and

intersection improvements along major arterials during the non-recreationalseason and establish an equipment staging area that contains enough capacity to

minimize the amount of equipment deliveries into the area which would take

place during the recreational season.

The delivery of OS/OW components and materials will likely follow one of the

proposed regional haul routes to access the project area. The proposed haul routes

for OS/OW components and materials were selected to minimize disruptions tomotorists and residents. Local school officials and emergency response

representatives will be notified in advance of temporary closures or traffic

restrictions required to improve intersections to accommodate OS/OW loads or cross roadways with utility lines.

It is expected that equipment and materials will be delivered to the site during

normal construction hours. The heavy equipment and materials needed for siteaccess, site preparation and foundation construction are typical of road

construction and do not pose unique transportation considerations. The delivery of

OS/OW turbine components will create the greatest impact to motorists as these

large transport vehicles will be slow moving and will require additional time tonavigate turns. The deliveries of OS/OW components have the potential to inhibit

operations along the major two-lane highways (NYS Route 12) during peak hoursand deliveries of such OS/OW turbine components should be limited to off-peak

hours to minimize the disruption to motorists. According to NYSDOT Traffic

Count Hourly Reports for NYS Route 12, which is located along the regional haul
