Requirement 2 continued -Threatened species:any species which is likely to become an endangered species -Endangered species:any species which is in danger of extinction throughout all or significant portion of its range -Pollution prevention:any practice which reduces the amount of a hazardous substance,pollutant, or contaminant released into the environment -Ozone:a layer of the earth’s upper atmosphere that is characterized by high ozone content which blocks most of the sun’s UV radiation from entering lower atmosphere -Watershed:describes an area of land that contains a common set of streams and rivers that all drain into a single larger body of water

Construction project sample Requirement 5 The highway and bridge known as SR 520 is a connecting bridge between Seattle and Redmond. The area is environmentally sensitive because it’s home to a species of salmon that’s on the decline. It’s also an area of high seismic activity and is located near major geological faults. The project also covers wetlands and wants to expand over Lake Washington. The construction corridor is riddled w/ landfills, underground storage tanks (some leaking), and includes at least 1 heavily contaminated PCB site that is undergoing remediation.
