Hazardous Waste Program fact sheet
Division of Environmental Quality Director: Leanne Tippett Mosby

Have you ever wondered what the difference is between a waste and a product? A product can become a waste if a facility does not properly store the material or the product is beyond its shelf life. The Missouri Department of Natural Resources has developed this fact sheet to help generators determine if a product is really a waste.

Generators must use products for their intended purpose. If a generator is no longer using the product, it may be recycled or must be properly disposed and not abandoned or stored. A business storing a material that is a hazardous waste must comply with Missouri’s hazardous waste regulations.

The term “hazardous material” is very broad and encompasses many types of materials, including hazardous waste. However, the hazardous materials are not necessarily wastes and may be materials in usable condition. Hazardous materials may have additional storage requirements.

Criteria for determining if a material is a product or waste
When determining if a material in storage is a product or waste, the generator should consider the following criteria:

Is the waste hazardous?
Once you have determined if a material is a waste, you must determine if that waste is hazardous or non-hazardous. The generator should first determine if the waste is excluded from regulation under 40 CFR 261.2. If the waste is not excluded, then the generator is required to determine if the waste is listed as a hazardous waste in subpart D of 40 CFR 261. The generator must further determine if the waste exhibits a hazardous waste characteristic, as identified in subpart C of 40 CFR 261. The generator may do this by testing the waste according to methods set forth in that same subpart or by using knowledge of the hazardous characteristics of the waste.  For more detail please see the publication Making a Hazardous Waste Determination found at http://dnr.mo.gov/pubs/pub919.htm

Additional considerations and sources
Hazardous waste requirement are found in the Missouri Hazardous Waste Management Laws, Sections 260.345 through 260.575 of the Revised Statures of Missouri (RSMo). The Missouri Hazardous Waste Regulations are found in Title 10, Division 25 of the Code of State Regulations (CSR). Most of the federal environmental requirements in Title 40 of the Code of Federal Regulations (CFR) are adopted by reference into the Missouri regulations.
