Western will furnish outdoor wiring diagrams no sooner than October 1, 2011. Control board wiring diagrams will be furnished no sooner than December 2, 2011. Include these restrictions in the construction program.

5. SEQUENCE OF WORK/OUTAGE RESTRICTIONS: In addition to the restrictions listed in the standard specifications, the following outage restrictions shall apply:

a. The electrical operation of the transmission lines are under the jurisdiction of Western’s Watertown Operations Office. All outage requests by the contractor shall be subject to the approval of the COR. Approval or denial of an individual outage request will be based on transmission system electrical loads, system operating configurations and weather conditions at the time the outage is scheduled to begin. At any time because of transmission system electrical loads, system operating configurations, weather conditions or any condition which may cause an adverse effect on the transmission system operation or reliability, Western may deny an outage request or direct the Contractor to return facilities to operating conditions and release the applicable Special Work Permit.

b. Make all outage requests in writing to the COR a minimum of 3 weeks in advance.

c. Meeting the minimum advance notice requirement of 21 days does not guarantee an outage will be approved. To improve the chances of an outage being approved, all outages should be submitted with as much advance notice as practicable. Weather conditions and other system conditions such as other scheduled and non-scheduled (forced) outages must be evaluated against an outage request before approval can be granted.

Outages of the Granite Falls-Watertown No. 1 230kV line during the months of December, January, February, July and August (the winter and summer peak load use months) should be of limited duration to the extent possible. If an outage is required during a peak load month, it may be granted with proper advance notice when weather conditions (temperatures) and Bulk Electric System conditions (other scheduled outages) permit.

Outages during the off-peak months will allow for added scheduling flexibility and may be scheduled for an extended duration when Bulk Electric System conditions permit.

Outages of the Granite Falls-FL Blair 230kV line require the Bigstone Unit No.1 generation to be limited by 126 MW to 349 MW net. Outages of this line should be planned such that they are of limited duration. The Bigstone unit is currently scheduled off-line from September 14th through November 3rd in 2011 and from May 30th through June 6th 2012 for maintenance. During the unit outages, extended duration outages of this line will be more readily available and should be scheduled to the extent possible. Outages during the months of December, January, February, July and August (the winter and summer peak load use months) should be avoided to the extent possible. If an outage is required during a peak load month, it may be granted, but limited to a night outage or a short duration day outage with proper advance notice when weather conditions (temperatures) and Bulk Electric System conditions (other scheduled outages) permit. Outages during the off-peak months should be of limited duration due to the generation reduction requirements but will allow for some added scheduling flexibility when Bulk Electric System conditions permit.

Once an outage has been approved and even after an outage has started, the outage may be subject to recall should the Bulk Electric System conditions or weather conditions change and warrant a recall or cancellation.

6. MAXIMUM AVAILABLE FAULT CURRENT: When protective ground leads are required, the protective ground leads shall be sized to carry the maximum available fault current in accordance with the Standard 1 – General Requirements, Section 1.4 “Safety and Health” and the following:

a. The maximum available fault current in the Appeldorn Substation area is 14,000 amps prior to completing construction.

7. TYPICAL FOUNDATIONS FOR CONTRACTOR FURNISHED EQUIPMENT:

Typical foundations for the Equipment Pad (mark STA1) and the Station Service pad (mark STA2) are shown on drawings APD 2303 and APD 2304 respectively; Western will finalize designs of these foundations after receipt of informational drawings and data from the equipment manufacturers. Contractor is to furnish final drawings of equipment to Western, upon which time Western will finalize the designs within the normal submittal review and processing time.

8. TYPICAL FOUNDATIONS FOR GOVERNMENT-FURNISHED ELECTRICAL EQUIPMENT:

Typical foundation for Transformer KV4A (mark TX1) is shown on drawing 2305. Western will confirm that design of this foundation is final after receipt of final informational drawings and data from the equipment manufacturer.

E. CONSTRUCTION PROGRAM:

1. SUBMITTAL TIME: Submit a construction program to the COR within 20 calendar days after date of Notice to Proceed.

The Contractor is responsible for unloading Western-furnished material, except for the power transformer, and steel poles. The Government furnished circuit breakers, disconnect switches, and fiber optic vault are stored at Western’s Granite Falls Substation. The contractor shall load, transport, and unload the circuit breakers, disconnect switches, and fiber optic vault from Granite Falls Substation to Appeldorn substation.

2. PROTECTION OF MATERIAL: Provide suitable indoor or warehouse storage for Items 12, 13 and 14. Provide protection against the elements after being removed from indoor storage and before installation. Approximately 500 square feet of indoor storage will be required.

G. RIGHTS-OF-WAY:

1. GENERAL: Transmission line right-of-way is 125 feet wide. Western does not represent that the Contractor can gain access to every structure site or travel continuously along the transmission line. Orient construction methods and equipment to utilize Government-Furnished rights-of-way, or obtain additional temporary access without additional cost to Western. Any additional temporary access acquired by the Contractor shall have prior COR approval since several areas of the transmission line have travel restricted areas. During the contract period, Western reserves the right to use Contractor-obtained access.

2. EASEMENTS: Western has acquired access easements from existing public roads to the transmission line and some off right-of-way access along the transmission line. This off right-of-way access route is to provide access to the transmission line structure sites not accessible by traveling the transmission line. Western has also acquired a permanent easement for installation of the HDPE pipe system in section 16 east of Appeldorn Substation.

3. WORK ON THE RIGHT-OF-WAY:

a. General: Perform work on the right-of-way necessary for access to or along the transmission line. Only that excavation, dozing, or blading that is absolutely necessary will be allowed. Excavation, dozing, and blading for ease of travel may only be performed after field review and approval by the COR. Unauthorized excavation, dozing, or blading shall immediately be repaired or Western will have the damage repaired and back-charge the Contractor for all costs involved.

b. Ease of Travel and Crane Landings: Excavation, dozing, or blading done for ease of travel on any easement or for crane landings shall be restored to the original contour of the land and shall be compacted to a dry density not less than the natural in-place dry density of the surrounding earth. The use of water may be required to obtain the required density. Topsoil shall be stockpiled and spread on cuts prior to completion of work.

H. GEOLOGIC INVESTIGATIONS:

Geologic logs of subsurface explorations included in the “Drawings” Division constitute the information and records of geologic investigations for the work.
