3.2 EAGLE NEST EXCLUSION ZONE RESTRICTIONS

Four active eagle nests in the project area were identified in 2016. The nests and the 660 foot buffer are located as shown on the contract plans.

Prior to start of the construction season in spring of 2021 and future years, the United States Fish and Wildlife Service (USFWS) will conduct eagle nest surveys for the project area. If the nests at these locations are determined to be active or if additional active nests are identified within the project area, the USFWS will notify the Contracting Officer.

The Contractor will be notified of new active nest locations and comply with the avoidance measures specified herein.

3.2.1 Required Bald Eagle Protection Act Avoidance Measures

The Contractor's activities near any active eagle nest shall comply with the avoidance measures of the Bald and Golden Eagle Protection Act (16 U.S.C.668-668c) as follows:

(1) Maintain a buffer, identified as the eagle nest exclusion zone, of at least 660 feet (200 meters) between project construction activities and any active nest.

(2) Restrict all project construction activities within 660 feet of any identified active eagle nest to outside the nesting season (i.e. outside the nesting season is from August through mid-January in the Midwest). The USFWS will determine when nesting activity has ended (i.e.,eaglets have fledged) and will notify the Contracting Officer that the Contractor may immediately proceed with construction activities within the eagle nest exclusion zone.

(3) Maintain established landscape buffers that may screen the activity from the nest.

3.2.2 Identification of Limits of Eagle Nest Exclusion Zone

Clearly mark the limits of all eagle nests. Show exclusion zones that overlay with the project features such as site access, dredging, and island construction.

3.3 PIGS EYE ISLAND HERON ROOKERY SCIENTIFIC AND NATURAL AREA (SNA)

The SNA is identified as an EXCLUSION ZONE with RESTRICTIONS, and is denoted on the contract plans. Do not enter the SNA exclusion zone boundary. Clearly mark the limits of the exclusion zone with floating in-water boundary markers in accordance with the Minnesota DNR's Public Waters Work Permit provided as an attachment in SECTION 01 57 20.00 13.

3.4 FISHERY PROTECTION Zones - Work Exclusion Dates

No activity affecting the bed of the protected water may be conducted between April 1 and June 30, to minimize impacts on fish spawning and migration. If this type of work is essential during this timeframe, it shall be done only upon written approval of the Area Fisheries Manager.

See contact list at:

http://files.dnr.state.mn.us/fisheries/management/dnr_fisheries_managers.pdf.

Should work begin elsewhere in the project area within these dates, all exposed soils that are within 200 feet of Public Waters and drain to those waters must complete erosion control measures within 24 hours.

SECTION 01 14 00.00 13 Page 4

All work must be in accordance with the Public Waters Work Permit provided as an attachment in SECTION 01 57 20.00 13.
