The facility's location in Ketchikan, a coastal community, underscores the importance of responsible waste management to safeguard the local environment.
Environmental context
Ketchikan is a coastal city in Southeast Alaska with a temperate rainforest climate, receiving high annual rainfall. This precipitation increases leachate generation at landfills, requiring robust leachate management systems to prevent groundwater contamination. Proximity to the Tongass National Forest and marine habitats means that any leakage could impact sensitive ecosystems. Landfill gas, primarily methane, must be collected to reduce greenhouse gas emissions and comply with Clean Air Act regulations. Community proximity also necessitates careful traffic and odor management.
