As a precautionary response to COVID-19, Ohio EPA is currently operating with most staff working remotely. If you are working with our staff on a current project and you know the name of the employee you are working with, email them at or call them directly. The Agency website has contact information for every district, division, and office. In order to reach us, please contact Ohio EPA’s main phone line at (614) 644-3020 or the main line for the division or office you are trying to reach.

After March 23, our district offices and Central Office will be temporarily closed and will have increasingly limited ability to receive deliveries, plans, etc. All entities are encouraged to submit plans, permit applications, etc., electronically where there are existing avenues to do so, such as the eBusiness Center (eBiz). Please refer to the list of available services on the main eBiz webpage. We encourage you to make use of all that apply, even if you have not used eBiz in the past. Plans under 25 MB can be emailed. For large plans over 25 MB, entities should work with the reviewer/division to upload via LiquidFiles. Directions for submitting docs via LiquidFiles is available on YouTube. We apologize for the inconvenience and thank you in advance for your understanding. If you wish to send hard copies of documents to any of Ohio EPA’s district offices, the best method to ensure we receive these documents is to send them via U.S. Mail. Since all offices are closed, deliveries outside of U.S. Mail (FedEx, UPS) will likely be returned because the offices are closed and deliveries cannot be made.

To report a spill or environmental emergency, contact the spill hotline (800) 282-9378 or (614) 224-0946

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:

Guidance Documents, Fact Sheets, and Reports


  • 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.
