1.3 WORK PHASES

A. The Work shall be conducted in one phase.

1.4 WORK UNDER OTHER CONTRACTS

A. General: Cooperate with separate Contractors so work on those contracts may be carried out smoothly, without interfering with or delaying work under this Contract. Coordinate Work of this Contract with work performed under separate contracts.

1.5 GOVERNMENT-FURNISHED MATERIALS

A. Government-Furnished Materials:

1. None anticipated.

1.6 CONTRACTOR USE OF SITE

A. General: Contractor shall have limited use of site for construction operations. Limit use of premises to work in areas indicated on drawings. Do not disturb portions of Project site beyond areas in which the Work is indicated.

1. Limits: Confine construction operations to limits of disturbance shown on the Drawings.

2. All staging areas shall be approved by the Contracting Officer.

3. Limit site disturbance, including earthwork and clearing of vegetation, to limits shown on the Drawings.

B. Storage of Materials: Confine storage of materials to designated staging areas as shown on the Drawings or in coordination with the Contracting Officer.

3. All trash cans that are not of bear-resistant design shall be located inside trailers or buildings.

4. Waste produced by the Contractor is the responsibility of the Contractor and may not be put in NPS containers.

5. All work site food and drink trash shall be placed in trash cans.

6. All barbecue units shall be stored in trailers and buildings when not in use.

7. Bird feeders are prohibited.

8. Pets are prohibited.

9. Feeding of any wildlife is prohibited.

10. Any mishandling of garbage, food, trash or other bear attractants described above will result in the responsible party receiving a citation subject to a fine and/or court appearance before the United States Magistrate.

N. All costs for bear management actions directly related to mishandling of garbage, trash, foods or other bear attractants shall be at no additional cost to the Government.

O. The Contractor, all employees, and their families present at the Park shall be required to attend bear orientation sessions presented by the NPS.

1.7 PUBLIC USE OF SITE

A. Contractor shall conduct his operations to ensure the least inconvenience to public and current residents of the Canyon, Mammoth and Northeast Government Areas. All traffic on Park Roads must be permitted to pass. If excavation, backfill or paving operations require a temporary closure of a street, the Contractor shall submit a Traffic Control Plan and route traffic on a clearly signed and marked detour. The Contractor will be required to provide, place and maintains signs for all detours.

YELL326141 01 11 00 - 5

B. The Contractor is responsible for clearing snow from the site within the work areas indicated on Drawings and as required to complete the Work. Contractor shall not conduct snow removal activities on Park main roads. Prior to any winter shutdown, all equipment, materials, and stockpiles must be located and adequately marked so they can be easily identified during snow plowing operations. All excavation must be backfilled prior to a winter shutdown.

C. Access into the Park will only be allowed upon presentation of proper identification with prior notification to the Park officials, or by securing gate passes or stickers.

If pesticide application is necessary near monarch butterfly habitat, select chemical formulations specific to the targeted pest, time applications to avoid monarch activity periods, establish buffers, and minimize drift to non-target areas by direct ground application. All chemical formulations shall be approved by the Contracting Officer.

9. WOLVERINE Conservation Measures: Contractor shall participate in orientations on how to avoid disturbing or encountering wolverines and other wildlife, including regulations regarding vehicle speed limits, food storage, disposal of garbage and other attractants, and approaching or harassing wildlife. \Any observation of wolverines within the proposed action area shall be reported to the Contracting Officer and appropriate action would be taken to reduce potential effects.

10. All equipment and tools shall be cleaned completely prior to entering the work zone to prevent the spreading of invasive species. Equipment shall be inspected for compliance.

16. To avoid impacts to migratory birds during the nesting season, vegetation or tree removal activities shall occur outside of March 1-August 15th for raptors and May 1-August 15th for songbirds. If within the March 1 � August 15th window a nest is suspected, because of observed structures or behaviors (e.g. large collections of sticks or smaller plant material in trees, birds carrying food into nest-like structures), the Contracting Officer shall be notified to ensure coordination with the NPS Bird Program Manager.

17. Project shall comply with NPS and Yellowstone National Park lighting guidelines. This will include but is not limited to low-level lighting, minimized glare, downward focused light fixtures, and energy efficient light sources.

18. To minimize the amount of ground disturbance, staging and stockpiling shall be located in previously disturbed areas if possible. All staging and stockpiling areas shall be approved by the Contracting Officer and returned to pre-construction conditions following construction. Fencing is required around construction zones and staging areas.
