Chapter 3—Affected Environmentworking at the site with respect to such hazards (U.S. Department of theAir Force, 1997—EA for Radar Upgrade at Clear Air Station, Alaska).Currently, a new solid state phased-array radar is being installed at ClearAFS to replace the existing Ballistic Missile Early Warning System radar.The new radar is expected to be operational in the fall of 2000. Groundlevelmeasurements taken at a distance of 305 meters (1,000 feet) froma similar radar as the proposed phased-array averaged 0.005 milliwatt persquare centimeter, well below the permissible exposure levels of 4milliwatts per square centimeter. In addition, the phased-array radar isnot expected to be a threat to fuel-handling operations or to groundbasedelectroexplosive devices (U.S. Department of the Air Force,1997—EA for Radar Upgrade at Clear Air Station, Alaska).Clear Airport is a small public airstrip northeast of the base. The runwayapproach clearance zones on the southern end of the runway are onClear AFS boundary (Clear AFS, 1993—Comprehensive PlanningFramework). The airstrip is primarily used by small private planes andhas no scheduled commercial service.3.8.1.2 Eareckson AS—Health and SafetyThis section describes the health and safety concerns for the affected baseproperty at Eareckson AS and the surrounding area. The ROI for healthand safety includes the base and adjacent public that could be affected bythe deployment of an XBR. The ROI for EMR human health effects is thebase and adjacent property. This ROI is based on the area where potentialeffects to human health are expected to occur (out to 150 meters [492feet]). The ROI for certain electronic equipment and aircraft (see below)includes an area up to 350 kilometers (217 miles). For a generaldescription of the health and safety resource area, see section 3.8.On-base SafetyThe Air Force has developed standards that dictate the amount of fireequipment that must be present based on the types of aircraft and totalsquare footage of base structures and housing. The Eareckson AS firedepartment meets these standards, maintaining four crash fire trucks, threestructural pumpers, and one spill response truck. One centrally locatedfacility houses the equipment. The positioning of this facility also meetsthe Air Force time and distance requirements for facility response.The threats to human safety from aircraft accidents at Eareckson AS havebeen addressed by the establishment of safety zones around the airfield.In order to minimize the risk at each end of the runway, a Clear Zone andApproach Zones have been designated. These zones have beenestablished to limit development around the airfield on the island (figure3.8-2).NMD Deployment Final EIS 3-233
