Care shall be taken to minimally disturbed wetlands soils and vegetation, all mitigation measure required by the Contractor will be incidental to item 20434 Stream Channel Excavation.

Q4) Can the Potlatch Corporation road adjacent to the site be utilized as a haul route for the Stream Channel Excavation?

Modification in the Scope of Work

The decommissioning of a small road system in Deer Gulch has been added to the scope of work. Please see the revised Section B, Section C, and Drawings attached. Stream bed simulation material can be used from the Deer Gulch Road Decommissioning. Excess material that is removed from the road bed must be disposed of at the Musselshell Quarry Site. The Deer Gulch Road Decommissioning is approx. 5 miles from the Jim Brown Creek Box Culvert site. The Mussleshell Quarry is approximately ½ mile from the Deer Gulch site.
