It is proposed that the 120th Fighter Interceptor Group of the Montana Air National Guard convert from 18 F-106 to 18 F-16 aircraft. Associated with this conversion are building modifications, land acquisition, and facility construction. The environmental assessment determined that the primary impacts of the conversion would be positive. Noise modeling using the NOISEMAP methodology showed that the maximum noise reduction, resulting from the conversion, at any ground receptor point is about 5 dB on the L/sub dn/ scale. The noise reductions vary with the distance of a receptor point from the runways - the greater the distance, the smaller the noise reduction. Conversion to the F-16 prior to completion of a ''hush house'' would result in a temporary increase in noise to the southeast of the airport over a commercial and industrial area. In addition, total air pollutant emissions from aircraft operations would be reduced as a consequence of the conversion. No significant adverse impacts are predicted as a result of the conversion from F-106s to F-16s. (ERA citation 12:005425)
