During the test event, the AN/TPY-2 radar and system components would operate at full power for up to 4 hours.

Approximately 40 individuals would be required to set up and breakdown the AN/TPY-2 radar and system components, operate the radar and system components, and provide security for the system. During test out, calibration and operation a maximum of approximately 30 individuals would be required to operate the radar and system components and provide security for the system. All of these individuals would temporarily reside in Juneau, Alaska and commute to and from the site daily. Upon completion of testing, MDA would return the equipment to VAFB and remove all visible infrastructure and fencing from the site.

Impacts to wildlife from artificial lighting would not be significant. All lighting will be focused downward, not away from the site.

Electromagnetic radiation (EMR) and radio frequency from radars may cause impacts. However, birds are not likely to remain continuously within the radar beam and the power density is not expected to exceed levels that could impact birds; therefore, the likelihood of harmful exposure is remote.

As described in the Mobile Sensors Environmental Assessment (2005), the AN/TPY-2 radar and system components require a total of 2.1 megawatts of power to operate. Electric power would be provided to the site by Alaska Electric Light and Power (AELP) in accordance with State approved AELP procedures and Federal/State requirements (may require additional line and poles to be installed within existing right of ways and previously disturbed areas, per existing AELP permits). Small backup generators may be at the site for emergency use and would be periodically exercised according to maintenance schedules.

The AN/TPY-2 radar and system components typically require approximately 0.8 hectare (2 acres) of graded compacted hardstand surface (shown as tan area in Exhibit 2) and approximately 5 hectares (12 acres) of “clear zone” (green shaded area) to allow unobstructed, low-elevation radiation. Contained within the clear zone is a “hazard clear zone” of approximately 2.5 hectares (6 acres). At TSMRI, the majority of the clear zone is located in airspace above Favorite Channel and the AN/TPY-2 radar hardstand would be located in an area with controlled access using temporary fencing to prevent unauthorized entry to the hazard clear zone.
