ENVIRONMENTAL OVERVIEW Hazardous Materials, Pollution Prevention, and Solid Waste. Construction associated with the project could generate solid waste. Waste would be handled according to federal, state, and local rules and regulations. Water Resources. The project has the potential to affect water resources, specifically wetlands and surface water. Prior to the start of ground disturbing activities, the Airport would be responsible for having these wetlands officially delineated in order to determine the regulatory agency with jurisdiction over the wetlands, and the appropriate mitigation for potential effects. Assuming that the wetlands are regulated by the U.S. Army Corps of Engineers, the Airport would be responsible for obtaining a nationwide permit or individual permit, depending on the extent of the potential impacts. With regards to surface waters, the project would increase impervious surface. The increase in impervious surface would increase the volume of stormwater runoff; however, the existing stormwater drainage system is anticipated to be able to accommodate the increase in stormwater runoff. Because the project would disturb over one acre of land, the Airport would be responsible for obtaining a NPDES 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 project would not affect Section 4(f) resources; farmlands; historical, architectural, archaeological, and cultural resources, land use, noise and noise-compatible land use; socioeconomics, environmental justice, and cenvironmental health and safety risks; visual effects; or floodplains because it would not increase the number of aircraft operating at the Airport, change current runway use, relocate residences or businesses, or require land acquisition. The construction, repair, reconstruction, resurfacing, extension, strengthening, or widening of a taxiway can be categorically excluded under FAA Order 1050.1F, paragraph 5-6.4(e), provided that the project would not cause significant erosion or sedimentation, would not cause a significant noise increase over noise sensitive area, or cause significant impacts to air quality. Because the project would not increase the number of aircraft operating at the Airport or significantly change the runway use, the project would not effects are not expected to be significant, and adherence to NPDES permit provisions would minimize erosion and sedimentation effects. For those reasons, a CATEX is anticipated to be the appropriate NEPA documentation for this project. Mid-Term CIP Projects Mid-term CIP projects include projects planned between 2023 and 2027 (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. 7.3.2.1 Airfield and Support Facilities It is recommended that the Airport group the following mid-term CIP projects intoa single NEPA document for analysis: EUGENE AIRPORT MASTER PLAN 7-16
