ENVIRONMENTAL OVERVIEW adherence to the provisions in the required permits and plans would minimize potential effects to surface water and groundwater. The project would not affect Section 4(f) resources (unless historical resources are identified in ground disturbing areas); socioeconomics, environmental justice, and cenvironmental health and safety risks (unless relocation is associated with the land acquisition); or floodplains. An EA is anticipated to be the appropriate NEPA documentation for this project. Long-Term CIP Projects Long-term CIP projects include the projects planned between 2028 and 2037 (see Chapter 5, Implementation and Financing Plan). The suggested NEPA documentation for those projects and/or grouping of projects is provided below, along with a preliminary analysis of the potential environmental effects associated with those projects. 7.3.3.1 Terminal Area, Airfield, and Landside Facilities It is recommended that the Airport group the following long-term CIP projects into a single NEPA document for analysis: » Deicing Facilities and Segmented Circle Relocation » Runway 16R-34L Rehabilitation » Replace Runway 34L VASI with PAPI (LED) Approach Guidance System » Landside Vehicle Parking Expansion » Construction Vehicle Access Tunnel Under Taxiways C and M Grouping multiple projects into one NEPA document allows the Airport to maintain maximum project construction flexibility based on when federal funding for CIP projects become available. The project, as grouped above, may affect the following resource categories: Air Quality. The project would temporarily increase emissions from construction vehicles and equipment. The increase would be temporary and minor. A construction emissions inventory may be necessary for the NEPA documentation associated with this project. Biological Resources. The area is currently paved and the area surrounding the taxiway is mowed and maintained grassland and includes previously identified wetlands. Given the location of the area (on Airport property in an active portion of the airfield), it is unlikely that species utilizing the area are non- mobile. It is expected the species would leave the area during disturbance and utilize similar habitat found elsewhere in the area. However, a federally-threatened species, the Streaked horned lark (Eremophila alpestris strigata) is known to be present throughout portions of the Airport. It is recommended that a biological survey be conducted for the presence-absence of this species. In addition, the project would include the acquisition of land, which has not been previously surveyed. It is suggested that a biological survey of the area be completed before the acquisition of the land. EUGENE AIRPORT MASTER PLAN 7-19
