What Is A Hazardous Waste Manifest & What Do You Do With It?

According to DTSC, (Department of Toxic Substances) a uniform hazardous waste manifest must accompany most hazardous waste that is shipped off site. The Uniform Hazardous Waste Manifest is the shipping document that travels with hazardous waste from the point of generation, through transportation, to the final treatment, storage, and disposal facility (TSDF). 

Each party in the chain of shipping, including the generator, signs and keeps one of the manifest copies, creating a "cradle-to-grave" tracking of the hazardous waste.  EPA ID numbers are needed by all parties on the manifest.  Hazardous waste transporters in California must be registered with the Department of Toxic Substances Control.

So how does this apply to you as a hazardous waste generator?

Once your hazardous waste has been stored and labeled properly, you are required to complete the Hazardous Waste Manifest outlining what hazardous waste types you are disposing of and how much of it. You must then mail a copy of this manifest to the DTSC. The hazardous waste manifest is a TRACED document which the DTSC monitors and regulates to ensure that your waste is bring handled appropriately and within the law.hazardous waste manifest

Make Sure Your Waste Is Being Delivered Correctly

Next, your hazardous waste transporter will pick up your waste and must dispose of it within 10 days to a designated facility. The designated facility then has 30 days to with which to send the signed manifest to DSTC to prove that your waste has been delivered and processed correctly. If the DTSC does not receive the signed manifest within 30days, the transporter will be paid a visit by the DTSC to make sure your waste is not being dumped out in a hole in the desert. This is just one of the many reasons a hazardous waste generator should hire a professional and reliable hazardous waste transporter. Since you, as a the original generator of the waste, are responsible for what happens to the waste from "cradle to grave." It's vital you know where your transporter is disposing of your waste. You could end up with significant fines if you find out later that your transporter just dumped the waste out somewhere they aren’t supposed to.

TSDF Receipt of Acceptance and Processing

Once your transporter has delivered the waste to a designated facility, the facility signs the manifest with a 3rd signature (TSDF receipt of acceptance and processing) and sends that to you the generator. This way you know that your waste has been delivered to its final destination and treated accordingly. 


It is very important to match the final signed manifest with the one the transportation company driver gave you when they picked up your waste. Place these two manifests in a folder and save them for at least 5 years.

Its also important to remember that only the hazardous waste manifest needs to be mailed. Non-Hazardous Materials do not need to be mailed.
