Chapter 3—Affected Environmentmaintained with the fire departments in the towns of Langdon <strong>and</strong>Nekoma. The mutual aid agreements allow access by the firedepartments to the site for responding to fires or accident/injuryassistance (U.S. Army Space <strong>and</strong> Strategic <strong>Defense</strong> Comm<strong>and</strong>, 1994—Memor<strong>and</strong>um of Agreement between Langdon, North Dakota Fire District<strong>and</strong> U.S. Army Space <strong>and</strong> Strategic <strong>Defense</strong> Comm<strong>and</strong>; Memor<strong>and</strong>um ofAgreement between Nekoma North Dakota Fire District <strong>and</strong> U.S. ArmySpace <strong>and</strong> Strategic <strong>Defense</strong> Comm<strong>and</strong>).Electromagnetic Radiation EnvironmentFor purposes of this study, the electromagnetic environment around the<strong>Missile</strong> Site Radar includes all ground-based systems within a 30-kilometer (19-mile) radius for out-of-b<strong>and</strong> systems <strong>and</strong> within a 350-kilometer (217-mile) radius for in-b<strong>and</strong>, adjacent b<strong>and</strong>, <strong>and</strong> harmonicallyrelated b<strong>and</strong>s. The out-of-b<strong>and</strong> communications-electronics environmentaround the <strong>Missile</strong> Site Radar was found to include 204 systems rangingin frequencies from 43 to 24,150 megahertz. The distribution of thesesystems over the electromagnetic spectrum, VHF–K-B<strong>and</strong>, is shown insection 3.8.2.1, figure 3.8-9. These systems were categorized intopotential sensitive receptors of frequency-related interference or nonfrequencyrelated interference.Communications–Electronics Frequency Related Interference. Theexisting ground-based communications-electronics environment aroundthe <strong>Missile</strong> Site Radar includes two in-b<strong>and</strong> systems: a precisionapproach radar in Minot, North Dakota, <strong>and</strong> a weather radar in ParkRapids, Minnesota. The airborne electromagnetic environment includesthree types of in-b<strong>and</strong> systems: fire control, bomb/navigation, <strong>and</strong>weather radars. Weather radars are utilized on both civilian <strong>and</strong> militaryaircraft. Section 3.3.2.1 provides an overview of the airspace <strong>and</strong>airports in the <strong>Missile</strong> Site Radar ROI.Communications–Electronics Non-frequency Related Interference. Theout-of-b<strong>and</strong> electromagnetic environment (within 30 kilometers [19 miles])at the <strong>Missile</strong> Site Radar included 204 ground-based systems. Themajority of the systems (191 systems) are l<strong>and</strong>-mobile UHF <strong>and</strong> VHFradios. Also included are one FM radio station, one air navigation beacon,five pager/cellular phone towers, five satellite communications systems,<strong>and</strong> one speed gun. Although no airborne systems are registered with theNTIA or FCC for this area, it is anticipated that various avionics equipment(tactical air navigation, IFF systems, glideslopes, beacons, etc.) will bepresent as aircraft travel in <strong>and</strong> out of the area.Radiation Hazards. Based upon the absence of high-power emitterswithin a 30-kilometer (19-mile) radius of the <strong>Missile</strong> Site Radar, theexisting electromagnetic environment does not present substantial levelsof radiation hazards to personnel, electroexplosive devices, or fuels.NMD Deployment Final EIS 3-253
