These attempts must occur at least 14 days prior to any ground disturbance. If no response is received after these documented efforts, the Contractor may proceed with construction activities.

Tribal and Archeological monitors must be present during all ground disturbing activities including but not limited to:

• Erosion control installation and management

• BMP installation

• Clearing and Grubbing

• Culvert cleaning, lining and replacement

• Culvert outlet grading

• Ditch grading

(2) In the event of an archaeological discovery during construction, stop all work in the vicinity of the discovery and notify the CO. Coordinate with the CO to take measures to prevent further impacts or to mitigate loss in accordance with 36 CFR 800.13.
