On-Site Waste Management
Some generators manage a portion or all of their waste on their own site. These generators may use a variety of waste management methods for managing waste on-site such as incineration or thermal destruction, landfilling, non-thermal destruction, or physical/chemical treatment. Wastes disposed of on-site are subject to the waste tonnage fee requirements of Regulation 347. For generators who ship their wastes offsite, waste tonnage fees are collected as manifests detailing waste quantities are processed in HWIN. Generators who manage waste on-site do not use a manifest, and HWIN has set up a different mechanism to collect waste tonnage fees for wastes managed on-site. Please select YES below if you manage a portion or all of your waste on-site.
