How is solid waste stored on-site before disposal?

After excavation, solid waste removed from the site is temporarily staged in piles. These piles are securely covered with thick tarps. Liners are also installed below the piles, to help protect the ground underneath them. Berms are also in place to ensure rainwater that falls on the piles is collected and does not spread contamination. Each day, trucks arrive to load and transport this waste off-site for safe disposal.
