How to Choose a Hazardous Waste or Used Oil Contractor - A Help Guide

Essential Facts abouts TSDFs

Approximately 30 facilities located in Washington are actively accepting hazardous waste for treatment, storage, disposal (TSD), and recycling or used oil for processing into fuels. These facilities are owned and operated by private companies for commercial purposes, by private companies to handle their own wastes (non-commercial), or by government agencies such as the military. Owners and operators of TSDs are subject to hazardous waste permits and regulations. Hazardous waste permits are not required for recycling or used oil processing (see checklist sections under Conditionally Exempt Recyclers and Used Oil Processors). The following are some facts about TSDFs.

Permits are written to allow treatment, storage, or disposal to occur at a facility. These activities generally pose a greater risk, requiring that site-specific permits be developed to mitigate, control, and prevent hazards to human health or the environment.

Permits address design, construction, operations, closure, and financial assurance for particular sites and waste management activities. Once issued, a permit is in force at that facility for up to 10 years and becomes the basis for compliance inspections.

What is a permit for, and what are the benefits of using a TSDF as my contractor?

A number of different hazardous waste management activities require a hazardous waste permit in order for a company to legally operate. Examples include storage in containers, tanks, lagoons or containment buildings; treatment in tanks or containers; fuel blending; incineration; and, land disposal.

Hazardous waste permits are developed for specific structures or buildings (units) where the storage, treatment, or disposal of hazardous wastes is occurring.

To file for, and receive, a final hazardous waste permit the applicant must provide detailed analysis and document a number of factors. These include site characteristics and the design, construction, operation, and closure of areas used for waste management, as well as requirements such as waste analysis, employee training, record keeping, and financial assurance.

Washington State commercial TSD facilities have permits for treatment and storage. There are no commercial TSD facilities in this state permitted to conduct disposal such as landfilling or incineration.
