P.O. Box 453 Cape May Point, NJ 08212 (609) 884-2842, fax 884-4569 [email protected] [email protected] Garden Peninsula Wind Energy Project, Delta County, MI Phase I Avian Risk Assessment Garden Peninsula Wind Energy Project Delta County, Michigan Executive Summary Heritage Sustainable Energy is proposing a utility-scale wind-power project of moderate size for the Garden Peninsula on the Upper Peninsula of Michigan in Delta County. This peninsula separates northern Lake Michigan from Big Bay de Noc. The number of wind turbines is as yet undetermined, but a leasehold map provided to Curry & Kerlinger indicates that turbines would be constructed on private lands (i.e., not in the Lake Superior State Forest) in mainly agricultural areas on the western side of the peninsula, and possibly on Little Summer Island. For the purpose of analysis, we are assuming wind turbines with a nameplate capacity of 2.0 MW. The turbine towers would likely be about 78.0 meters (256 feet) tall and have rotors of about 39.0 m (128 feet) long. With the rotor tip in the 12 o’clock position, the wind turbines would reach a maximum height of about 118.0 m (387 feet) above ground level (AGL). When in the 6 o’clock position, rotor tips would be about 38.0 m (125 feet) AGL. However, larger turbines with nameplate capacities (up to 2.5 MW and more) reaching to 152.5 m (500 feet) are may be used.

IX.1 Rock Lake NMF Conducted surveys with assistance from Otto Jacob during one of the days. Surveys focused on dry-mesic northern forest and granitic features within the forested matrix. Documented high-quality dry-mesic northern forest, granite bedrock glade, granite cliff, poor fen, northern wet meadow, and submergent marsh. The juxtaposition of high-quality bedrock features adjacent to high-quality wetlands was notable. In addition, the following natural communities were identified as inclusions or zones within these communities or were noted in passing during the course of surveys: rich conifer swamp, muskeg, and northern shrub thicket.

    ACTIVITY 7 – MARKING GUIDELINE: 1. A – Cuesta B – Homoclinal ridge C – Hogsback 2. Sedimentary 3. Inclined rocks with different resistance to erosion. Soft rock erodes away more quickly than hard rock. 4. The dip slope is 10–25° to the horizontal. Folding can result in cuesta basins and cuesta domes. 5. Farming can take place on dip slopes. Roads and railways can be built parallel to these landscapes. Gaps or poorts between homoclinal ridges can be good sites to build dams. Cuesta basins yield artesian water. Cuesta domes may contain oil and natural gas (fracking). Fertile valleys and plains between cuestas are suitable for human settlements. These ridges are used for forestry, tourism, recreation and nature conservation. These ridges can be used for defence purposes. (Accept any relevant answer) ACTIVITY 8 – MARKING GUIDELINE: 1. It occurs when strata are subjected to stress (compression, tension, volcanic intrusion, or tectonic movement) and they become tilted relative to their original (horizontal) position. Faulting or folding causes the strata to be tilted. The beds may be inclined in any direction with the angle of the dip slope between 0º to 90º. 2. Cuesta dome 3. The scarp slope faces inward, and dip slopes faces outward. 4. HOMOCLINICAL RIDGE: HOGSBACK: 5. HOMOCLINICAL RIDGE: HOGSBACK: • The angle of the dip slope lies 25º – 45º; • The angle of the dip slope is more than 45º; • Rivers cut poorts through the ridges; • There is very little difference in the gradient of the scarp and dip slopes ACTIVITY 9 – MARKING GUIDELINE: 1.
