The Contractor shall receive notice of acceptance from NDOT environmental, prior to starting the above listed project activities. These project activities cannot adversely affect state and/or federally listed species or designated critical habitat.

WASTE/DEBRIS

1. Construction waste/debris shall be disposed of in areas or a manner that will not adversely affect state and/or federally listed species and/or designated critical habitat.

POST CONSTRUCTION EROSION CONTROL

1. Erosion control activities carried out by NDOT Maintenance or others after construction is complete, but prior to project close-out, shall adhere to any standard conservation conditions for species designated for the project limits during construction.

PLATTE RIVER DEPLETIONS

1. To the maximum extent practical, efforts will be made to design the project and select borrow sites to prevent depletions to the Platte River. If there is any potential to create a depletion, NDOT (during design) and the Contractor (for borrow sites) shall follow the current Platte River depletion protocols for coordination, minimization, and mitigation. In general, the following are considered de minimis depletions, but may still require agency coordination; a project which:

a. creates an annual depletion less than 0.1 acre feet

b. creates a detention basin that detains water for less than 72 hours

c. diverted water that will be returned to its natural basin within 30 days

d. creates a one-time depletion of less than 10 acre feet.

ASPHALT PLANTS AND STAGING AREAS

1. Asphalt plants and staging areas for construction supplies and Contractor's equipment shall be located in areas that are frequently disturbed such as, but not limited to, field entrances, crop fields, abandoned roadway, farmsteads, and roads. If this is not possible, the Contractor shall coordinate with NDOT Environmental with a site plan showing the desired staging/stockpile location(s), which will be sited in such a way as to avoid impacting protected species.

PIPING PLOVER

1. For construction activities that begin prior to April 15 and continue beyond April 15, surveys will be conducted starting April 8 and continue through the end of construction

- 12 -or August 15 whichever comes first. NDOT Environmental, NDOT trained personnel, or a qualified biologist, will conduct surveys according to protocol at the following locations:

a. Mile Marker 72.40 (location of suitable habitat).

If species are present the District will notify the Contractor to stop work within ¼ mile of nesting activities and follow the protocol to determine when work can resume.

2. When initiating construction activities between April 15 and August 15, surveys will start one week prior to construction activities and will continue through the end of construction or August 15, whichever comes first. NDOT trained personnel, or a qualified biologist, will conduct surveys according to protocol at the following locations:

a. Mile Marker 72.40 (location of suitable habitat).

If species are present, the District will notify the Contractor to stop work within ¼ mile of nesting activities and follow the protocol to determine when work can resume.

WHOOPING CRANE

1. Construction activities will not occur during Whooping Crane migration periods. (Spring migration: March 6 – April 29; and fall migration: October 9 – November 15).

OR

2. If construction activities occur during Whooping Crane migration periods (Spring migration: March 6 – April 29; and fall migration: October 9 – November 15), NDOT trained personnel, or a qualified biologist, will conduct surveys according to protocol at the following locations: Project Length (location of suitable habitat). (prior to the start of daily construction activities). If species are present, the Engineer will notify the Contractor to stop work within ½ mile of the Whooping Crane and follow the protocol to determine when work can resume (also not initiate work if species is found in the morning survey). Options for resuming work may include but are not limited to:

a. Construction activities are limited to the hours from 10:00 am to 4:00 pm (CST) during the migration period, unless morning survey indicates Whooping Cranes are not present.

b. If a Whooping Crane is observed during the survey within ½ mile of the project but departs the area (further than ½ mile from the project), then work can resume. Document this departure according to protocol.

BALD AND GOLDEN EAGLE PROTECTION ACT

1. Suitable Bald Eagle nesting and/or roosting habitat exists within 0.5 miles of the

Environmental Study Area. If construction will begin between February 1 and April 15, a nest survey must be completed at least 1 but not more than 14 days prior to construction.

If construction will begin between April 15 and October 1, a nest survey completed in March is sufficient, as nests will likely already be constructed if nesting will occur that year.

- 13 -

However, a nest survey may be completed anytime during this timeframe, as long as it is completed prior to construction. If Bald Eagles are nesting in the area, consultation with NGPC and USFWS will be required prior to beginning construction activities. Eagle roosting surveys will be conducted if construction occurs between October 1 and January 31.

TRAFFIC DISRUPTION

1. This project shall be constructed under traffic with lane closures controlled by approved temporary traffic control.

S-2 Platte River Depletions. To the maximum extent practical, efforts will be made to design the project and select borrow sites to prevent depletions to the Platte River.

If there is any potential to create a depletion, NDOT (during design) and the

Contractor (for borrow sites) shall follow the current Platte River depletion protocols for coordination, minimization, and mitigation. In general, the following are considered de minimis depletions, but may still require agency coordination; a project which: a) creates an annual depletion less than O.1 acre feet, b) creates a detention basin that detains water for less than 72 hours, c) diverted water that will be returned to its natural basin within 30 days, or d) creates a one-time depletion of less than 10 acre feet. (NDOT Roadway Design, Contractor)

S-3 Revegetation. All permanent seeding and plantings (excluding managed landscaped areas) shall use species and composition native to the project vicinity as shown in the Plan for the Roadside Environment. However, within the first 16 feet of the road shoulder or within high erosion prone locations, tall fescue or perennial ryegrass may be used at minimal rates to provide quick groundcover to prevent erosion, unless state or federally listed threatened or endangered plants were identified in the project area during surveys. If listed plants were identified, any seed mix requirements identified during resource agency consultations shall be used for the project. (NDOT Environmental)

S-4 Sensitive Areas. Environmentally Sensitive Areas will be marked on the plans, in the field, or in the contract by NDOT Environmental for avoidance. (NDOT

Environmental, NDOT Roadway Design, District Construction)

S-5 Species Surveys. If species surveys are required during the construction phase of the project (including pre-construction surveys), results will be sent by NDOT

Environmental Section to the USFWS, NGPC, and if applicable the USAGE.

(NDOT Environmental, District Construction)

R-4 For activities within suitable habitat for the listed plants where a NE determination is made, include the following mitigation measure: Asphalt plants and staging areas for construction supplies and Contractor's equipment shall be located in areas that are frequently disturbed such as, but not limited to, field entrances, crop fields, abandoned roadway, farmsteads, and roads. If this is not possible, the contractor shall coordinate with NDOT Environmental with a site plan showing the desired staging/stockpile location(s), which will be sited in such a way as to avoid impacting protected species.

Bald and Golden Eagle Protection Act

• Suitable Bald Eagle nesting and/or roosting habitat exists within 0.5 miles of the

Environmental Study Area. If construction will begin between February 1 and April

15, a nest survey must be completed at least 1 but not more than 14 days prior to construction. If construction will begin between April 15 and October 1, a nest survey completed in March is sufficient, as nests will likely already be constructed if nesting will occur that year. However, a nest survey may be completed anytime during this timeframe, as long as it is completed prior to construction. If bald eagles are nesting in the area, consultation with NGPC and USFWS will be required prior to beginning construction activities. Eagle roosting surveys will be conducted if construction occurs between October 1 and January 31. (NDOT
