At several of our landfills, we provide financial assurance by depositing cash into restricted trust funds for purposes of settling final capping, closure, post-closure and environmental remediation obligations. Generally, these trust funds are established to comply with statutory requirements and operating agreements. See Note 12 for additional information related to these trusts.
