This Finding of No Significant Impact (FONSI) is based on the October 2008 EA. After independent evaluation of the EA, MDT and FHWA conclude that the EA adequately and accurately discusses needs, environmental issues and environmental impacts of the proposed project and appropriate mitigation measures. The EA provides sufficient evidence and analysis for determining that an Environmental Impact Statement (EIS) is not required. MDT and FHWA take full responsibility for the accuracy, scope, and content ofthe October 2008 EA. For purposes of compliance with the Montana Environmental Policy Act (MEPA) (ARM 17.4.609(3)(j) and ARM 18.2.239(3)0)), this FONSI and conclusion that an EIS is not required should be considered part^df the EA.

This document has been developed in accordance with the NEPA (National Environmental Policy Act) of 1969, as amended; Council on Environmental Quality regulations, Parts 1500-1508; the MEPA (Montana Environmental Policy Act); and other applicable laws and regulations. The EA, which is included in Appendix C, describes the potential environmental impacts of reconstruction of US Highway 212 from 8 Street in Red Lodge, Montana to approximately 1,000 feet north of Boyd, Montana. 2.0 SELECTION OF PREFERRED ALTERNATIVE Following the identification of the purpose and need for the proposed project and the project objectives, numerous improvement scenarios were developed and evaluated. These scenarios were modified and refined based on input from elected officials and the general public as well as data collected pertaining to engineering factors, environmental considerations, and existing and planned development along the corridor. The result of this process was the consideration of two alternatives: a no-build alternative and a build alternative (identified as the Preferred Alternative in the EA). Of the two alternatives analyzed in the EA, the build alternative is the Preferred Alternative for the proposed project. Please referto Table 1, Summary ofPreferredAlternative. The Preferred Alternative meets the project purpose and need by: o Improving the pavement condition along the project corridor by reconstructing the roadway. o Improving the intersection geometry at key locations along the corridor. o Incorporating an Access Management Plan for Red Lodge, which was supported by the Red Lodge City Council in March 2007. o Providing pedestrian and bicycle facilities in Red Lodge. o Improving level of service by providing passing lanes in rural segments where appropriate and making improvements at the 8lhStreet/US Highway 212 and MT Highway 78/US Highway 212 intersections. o Providing wider roadway shoulders in rural segments where appropriate. o Flattening ditch slopes in rural segments where appropriate. o Reducing clear zone encroachments in rural segments where appropriate. Providing increased snow storage with wider and deeper roadside ditches. Clearing thick brush and trees within the clear zone to improve driver visibility of approaching wildlife. Providing turning lanes where needed to reduce differential speed conflicts. Improving highway-related storm water drainage in Red Lodge and Roberts.
