1 The wetland delineation boundary provided for Wetland 2 included only the eastern edge of the wetland (oxbow area). The end points of the delineation boundary were connected and the resulting polygon totals 9.3 acres. The total area of wetland 2 including the area outside of the boundary shown on the plans is estimated to be up to 30 acres.

ALTERNATIVES: No Action Alternative. The No-Build Alternative is a non-construction alternative that would maintain the existing conditions along the entire length of the corridor and only minor upgrades through routine maintenance would occur to MT 117. The No-Build Alternative would not address the purpose or need for the Proposed Action for the following reasons: ·

·

·

Safety concerns: the existing horizontal alignments, roadway widths, side slopes and pavement conditions would remain along MT 117, contributing to safety concerns. The current at-grade railroad crossing would continue to be an area of concern as train and vehicle volumes increase in the future. Emergency vehicle response time: emergency vehicles would continue to utilize the at-grade crossing in Nashua to access residences to the south of the railroad. Crossing closures would continue to affect emergency vehicle response times. Roadway deficiencies: roadway widths, side slopes, and pavement conditions would continue to be insufficient compared to current MDT design criteria.

Overall, the objective of improving conditions on MT 117 and providing a grade-separated connection to US 2 for the purpose of improving safety and mobility would not occur under the NoBuild Alternative. As such, the No-Build Alternative is not practicable as it would neither meet the purpose and need of the project nor the transportation needs of the public.

Alignment Alternatives. Four alignment alternatives were considered and are summarized below. The preliminary wetland impacts that supported the alternatives analysis and selection of the preferred alignment were based upon preliminary engineering and roadway modeling and limited geotechnical information at the time of analysis. The table below includes the preliminary findings for the four build alternatives examined. Through final design and alignment modifications to minimize private property impacts, the final estimated wetland impacts for the preferred alignment, West Alignment Option 1, have increased. The preliminary wetland impacts for the other alternatives would have increased similarly in proportion and therefore the preliminary wetland impacts presented in Table 1 still provide a valid comparison of scope of impact between alternatives. The primary distinguishing difference between the various build alternatives relates to the location of new alignment of MT 117 and overpass under consideration. The east options explore a new alignment that is located to the east of a homestead property (Ersland property) situated at the northwest corner of the existing MT 117/County Road intersection and the west options provide for two alternatives on the west side of the Ersland property. Refer to Figure 1 for a depiction of the alternative alignments. Summary of Preliminary Build Alternatives Alternative

impacts reported were based on preliminary information at the time of analysis.

MITIGATION: Avoidance, Minimization and Compensatory Mitigation: The project design team has made all practicable efforts to avoid and minimize impacts to wetlands and streams. The wetlands were avoided to the greatest extent practicable. Wetlands occur in the immediate vicinity of the existing roadway throughout the project limits. Avoidance of all impacts was not possible due to the need to widen the roadway, flatten slopes, adjust the vertical grade to correct vertical sags, and replace the culverts and structures occurring along the project corridor. The following measures were incorporated in design to avoid and minimize wetland impacts to the greatest extent practicable while still achieving the improved roadway conditions and safety for the travelling public: ·

Wetland 1 (a small wetland located at approximately station 621+00 RT) was avoided completely by reducing the project footprint and fill slopes at this location. The realignment of

MT 117 begins at this location and the western shift of the alignment results in avoiding Wetland 1. The realignment of MT 117 was shifted as far east as possible to reduce the footprint and minimize impacts to the oxbow wetland (Wetland 2). Complete avoidance of Wetland 2 was not possible due to the private residence located at the junction of the existing MT 117 and County Road. The new intersection of Nashua Blvd. and MT 117 was shifted as far south as possible in order to reduce the footprint and impact to Wetland 5 and to utilize the existing footprint of Nashua Blvd. to greatest extent practicable while still maintaining design standards. Side slopes throughout the project were optimized to the extent practicable as to reduce the overall footprint. Reinforced soil slopes are utilized at the bridge abutments, as opposed to flatter slope paving options, reducing overall wetland impacts. The project will incorporate standard water quality BMP's during construction as specified in the standard specifications and special provisions of the contract documents, as well as following any special considerations as specified by the Section 404 permit.

To compensate for unavoidable impacts, the applicant proposes the following measures: Wetland Mitigation: The project as proposed would result in permanent impacts to approximately 7.92 acres of wetlands from the placement of fill, culverts, and irrigation structures. Unavoidable wetland impacts will be mitigated at the MDT Rock Creek Ranch wetland mitigation site located at Section 1, Township 27N, Range 43E, within Valley County. This mitigation reserve is located in the same watershed as the wetland losses; has been established in advance of the project impacts; and the wetlands at the Rock Creek Ranch wetland mitigation site have a higher wetland functional classification (category II) than the wetlands that will be unavoidably impacted (category III) by this project; therefore a replacement ratio of 1:1 will be used. Stream Mitigation: The project as proposed will not impact any river or stream banks. Impacts will occur to approximately 178 linear feet of jurisdictional irrigation ditch. Compensatory stream mitigation is not anticipated to be required. OTHER GOVERNMENTAL AUTHORIZATIONS: The Montana Department of Environmental Quality, 1520 East 6th Avenue, PO Box 200901, Helena, Montana 59620-0901 will review the proposed project with the intent to certify in accordance with the provisions of Section 401 of the Clean Water Act. The certification, if issued, will express the State's opinion that the operations undertaken by the applicant will not result in a violation of applicable water quality standards. The Montana Department of Environmental Quality hereby incorporates this public notice as its own public notice and procedures by reference thereto. CULTURAL RESOURCES: Historic properties eligible for or included on the National Register of Historic Places (NRHP) are protected under Section 106 of the Historic Preservation Act and Section 4(f) of the 1966 Department of Transportation Act. Tribal cultural resources are protected through the Native American Graves Protection and Repatriation Act and the Archaeological Resources Protection Act. The Federal Highway Administration (FHWA) is the lead Federal Agency for the proposed project and is responsible for ensuring compliance with these regulations. A cultural resource report was completed and found several historic properties in the project area that are listed or eligible for listing on the NRHP. One site was later deemed ineligible for listing. A determination of No Adverse Effect to Historic Properties was made for the proposed project.
