Hazardous Waste Treatment, Storage and Disposal Facilities

Treatment, storage, and disposal facilities (TSDF) are the last link in the cradle-to-grave hazardous waste management system. The requirements for TSDFs, are more extensive than the standards for hazardous waste generators and transporters. They include general facility operating standards, as well as standards for the various types of units in which hazardous waste is managed. General facility standards address good management practices for any facility engaged in hazardous waste management.

The technical standards go beyond these requirements to ensure that all elements of the TSDF are constructed and operated to prevent leaks of hazardous waste into the environment. The technical standards also address the diversity of hazardous waste operations being conducted around the country by guiding facilities in the proper design, construction, operation, maintenance, and closure of a variety of hazardous waste treatment, storage, and disposal units. These unit standards include requirements for a wide range of hazardous waste management units, from containers (e.g., 55-gallon drums) to landfills, in order to ensure that these units handle waste safely and effectively.

With some exceptions, a TSDF is a facility engaged in one or more of the following activities:

  • Treatment – Any method, technique, or process designed to physically, chemically, or biologically change the nature of a hazardous waste.

  • Storage – Holding hazardous waste for a temporary period, after which the hazardous waste is treated, disposed of, or stored elsewhere.

  • Disposal – The discharge, deposit, injection, dumping, spilling, leaking, or placing of any solid or hazardous waste on or in the land or water. A  disposal facility is any site where hazardous waste is intentionally placed and where the waste will remain after a TSDF stops operation. 

The State of Ohio issues hazardous waste permits to applicants seeking to conduct certain hazardous waste management activities. The permits are legally binding and enforceable documents. Unless specifically exempted or excluded by Ohio hazardous waste rules, any person that treats, stores or disposes of hazardous waste must first obtain a hazardous waste permit. 

The permit contains terms and conditions that define the permittee’s obligations under Ohio’s hazardous waste rules and the operating boundaries within which hazardous waste management activities must be conducted. These terms and conditions then serve as the basis for compliance evaluations and, if necessary, subsequent enforcement actions to remedy any non-compliance.
