ENVIRONMENTAL OVERVIEW number of aircraft operating at the Airport, would not change the airfield configuration, and would not require the relocation of residences or businesses. An EA is anticipated to be the appropriate NEPA documentation for this project. 7.3.3.2 Terminal Area It is recommended that the Airport group the following long-term CIP projects into a single NEPA document for analysis: » North Ramp General Aviation Hangar Removal » New Terminal Concourse Expansion (including PBBs) » New Terminal Concourse Apron Expansion » Runway 16L RPZ Land Acquisition 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 associated with construction would likely be temporary and minor. Given the proposed terminal concourse expansion, there may be an increase in the number of aircraft and surface vehicles accessing the Airport, which would increase emissions. An operational and constructions emissions inventory would be necessary for the NEPA documentation associated with this project. Biological Resources. Portions of on-airport property that the project would affect include areas identified as wetlands, with the remaining areas consisting of paved land and mowed and maintained grassland. 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. 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. Farmland. The area proposed for acquisition is currently farmland. The Airport would need to coordinate with the Natural Resource Conservation Service regarding the conversion of farmland to another use, and would need to complete Form AD-1006, Farmland Conversion Impact Rating. Hazardous Materials, Pollution Prevention, and Solid Waste. In order for the Airport to acquire land, the Airport must complete an EDDA or other similar environmental site assessment. The EDDA provides information regarding the presence or absence of hazardous materials and potential contamination. If hazardous materials or contamination are identified during the EDDA, a remediation plan would be EUGENE AIRPORT MASTER PLAN 7-21
