A Deleterious Substance Transport Permit (DSTP) is a permit required for transporting deleterious substances. A DSTP is required in addition to other requirements, such as intrastate authority and/or UCR registration.

Carriers transporting deleterious substances in any quantity over 20 gallons, whether in intrastate or interstate commerce, must hold a current DSTP.

The term of permit is 1 year. It must be renewed annually.

To obtain a permit, you must complete the Application for a Deleterious Substance Transport Permit.

The cost for a permit is $350 annually.

If you already have an intrastate motor carrier license, you should already have liability insurance on file and will not need to show any further proof of insurance.

If you do not have an intrastate motor carrier license, you must file proof of liability insurance in accordance with OAC 165:30-3-11.

• You must have an active USDOT Number.
• You must show proof of access to a licensed disposal site for deleterious substances.
• You may need an intrastate motor carrier license and, if you are planning to engage in interstate transportation, you must register through the UCR program.
• If you intend to store deleterious substances in a truck yard wash pit, you must also obtain a Truck Yard Wash Pit Permit.
• If you intend to apply drilling fluids and/or other deleterious substances for soil farming purposes, you must also obtain a permit from the Oklahoma Corporation Commission's Oil and Gas Division.
