On page 173 of the Special Provisions, the provision titled CONCRETE SURFACE MILLING FOR BRIDGE DECK & APPROACHES is void.

The Special Provisions are amended to include the following:

CONTRACTOR USE SITE

(American Burying Beetle Mitigation Option)

The Contractor shall furnish suitable sites for the off-project operations necessary to construct the project in accordance with the contract requirements. Contractor Use Sites may consist of borrow sites, waste sites or other sites necessary for the staging or stockpiling of materials or equipment.

This project is located within an area that contains habitat generally suitable for the American Burying Beetle (ABB).

If the Contractor cannot locate Contractor Use Sites that do not require mitigation for disturbance of suitable ABB habitat - as determined during the site approval process - the NDOT may allow the Contractor the option to utilize NDOT mitigation credit at a cost of $6,000 per acre operating, and maintaining the mitigation site. The cost is calculated based upon the permanent impact ratio of 1.5 acres for every 1.0 acre disturbed.

Eligibility to use NDOT mitigation credit acres will be based on the following criteria:

1. Requested Contractor Use Sites have been formally submitted using the site approval processes described in the contract.

2. The Contractor shall include an estimated number of acres of ABB habitat disturbance with each site request.

3. The proposed sites conform to resource agency criteria and can be permitted except for the mitigation required for impacted suitable ABB habitat.

4. The Contractor provides documentation demonstrating that:

a. No Contractor Use Sites are available that would avoid disturbance to ABB habitat, or

b. Alternative Contractor Use Sites that do not impact ABB habitat are not located within reasonable proximity to the project.

5. NDOT approves the use of mitigation credits from the mitigation bank site.

NDOT will perform a site visit at the conclusion of project to assess the actual disturbed acres of suitable ABB habitat for each site approved to use mitigation credits. NDOT will measure the disturbed acres and calculate the final mitigation cost based on this assessment. The final cost will be deducted from monies owed on the contract.

The use of the NDOT mitigation credit acres must be approved in writing by the Department prior to allowing any project related activities to take place on the proposed Contractor Use Site.

The Special Provisions are amended to include the following:

CONCRETE SURFACE MILLING

Subsection 510.04 of the Standard Specifications is amended to include the following:

The Contractor shall use waterblasting equipment operated with sufficient consistent pressure to effectively clean the milled pavement surface of all dirt, foreign materials, loose surfacing material, and any residue before placement of the asphaltic concrete overlay. Care shall be taken to prevent any debris or construction materials from directly entering, or entering any inlets on the project that lead directly to:

1. waterways.

2. poorly vegetated ditches, or

3. Well-vegetated ditches having less than 200 feet between the conduit outlet and the point of discharge of the ditch into a waterway.

Inlets shall not be blocked or otherwise restricted in such a way to cause water to collect within an active traffic lane.

The concrete must be completely dry before placement of any asphaltic concrete on these areas.

Paragraph 10. of Subsection 510.04 of the Standard Specifications is void and superseded by the following:

10. All material salvaged from this operation shall become the property of the

Contractor and shall be removed from the project.

Concrete Surface Milling work shall be performed after Concrete Repair work.
