ENVIRONMENTAL OVERVIEW construction permit prior to the start of ground disturbing activities, and all construction activities would be required to comply with the provisions set forth in that permit. The Airport would also be required to update the SWPPP and SPCC Plan. The 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. 7.3.3.3 Primary Airfield and Landside Support Facilities It is recommended that the Airport group the following long-term CIP projects into a single NEPA document for analysis: » Taxiway L and Taxiway J Connection » Rental Car Maintenance Garage » Taxiway B Reconstruction and Shoulder Paving 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. Climate. Similar to the potential air quality effects, the construction and operation of the project has the potential to increase GHG emissions. An estimate of GHG emissions could be included with the construction emissions inventory. Hazardous Materials, Pollution Prevention, and Solid Waste. Construction associated with the project could generate solid waste. Waste would be handled and disposed according to federal, state, and local rules and regulations. Depending on the activities performed in the rental car maintenance garage, there is the potential for an increase in hazardous materials, such as fuel and cleaning materials. The Airport would be responsible for updating the SPCC Plan. EUGENE AIRPORT MASTER PLAN 7-23
