h. Electronic nissions: The electronic emis. ns will be I <br /> within the range assigned to the Aeronautical Service by the I <br /> Office of Telecommunications Policy. The electronic <br /> . i engineering for the installation will insure compliance with <br /> ; Telecommunications standards and restrictions. <br /> a <br /> � <br /> i . istorical and Archeoloqical Considerations: The affected <br /> � property for this project consists of Boeing Company's Building <br /> � 45-01 and the ad�acent concrete parking area. There is no <br /> : historical or archeological significance to this area. During <br /> ' construction excavation, if any artifar.ts are uncovered, <br /> ; appropriate action will be taken that will be consistent with <br /> � local , state, and federal regulations. <br /> : <br /> j J. Aesthetics: The proposed facility wi11 be compatible with <br /> " the existing airport environment. <br /> : <br /> a k. Cumulative lmoact: This pro,ject will have no incremental <br /> impact upon future air traffic patterns at Paine Field. The <br /> ` relocated facility will return the deteriorated VOR performance <br /> ; to the level intended when the VOR was originally installed. <br /> � VI. ALTERNATIVE ACTIONS: <br /> n <br /> � a. Alternative Sites: The Northwest Mountain Region <br /> , completed a staff study in May 1991 which addressed the <br /> 1 problems with the Paine Field VOR. The study investigated <br /> � �� seven sites on or near the airport and the selected site was <br /> chosen because it wi11 provide the best VOR coverage and also <br /> � will be less c�stly to construct than the other sites. <br /> � Three additional off-airport sites were investigated and <br /> � eliminated from consideration due to the high cost involved in <br /> land acquisition and site development. Environmental impacts <br /> would have been considerable at all three off-airport sites. <br /> ., <br /> ;� b. U�qradina Existina Facilitv: The possibility of replacing <br /> the equipment and revising the antenna array at the existing <br /> ' VOR was investigated and it was determined that the location <br /> � would still not provide adequate coverage. <br /> :i <br /> � c. Do Nothina: The do nothing alternative wauld result in <br /> � continued loss of instrument approaches to Paine Field and <br /> � restrictions to the area enroute air structure. <br /> ;: <br /> fi <br /> .� <br /> � <br /> VII. CONCLUSION: <br /> � The facility was assessed in accordance with Order 1050.10. No <br /> � significant adverse impact ta the environment is expected from <br /> � establishing this facility. <br /> � . Relocating the VOR will not alter the existing topography; will <br /> �� _' not disrupt any community, will not have a significant <br /> aesthetic or visual effect; will not affect any cultural or <br /> historical sites; will not alter any ecological systems; will <br />
