What Can you Do to Prevent an Overfill?

What is a DOL Card?
Regulated Storage Tanks (USTs) should be monitored constantly by operators. USTs that are based on tribal lands must also follow certain federal regulations. Every UST has to have overfill prevention in place if it is filled with more than 25 gallons of product at a time. The preventive measures must be installed in the tank to:
  • stop overflow
  • reduce chances of overflow
  • alert delivery personnel before the tank is full to the brim

How to prevent an overfill

  • Alarms should be set in place to alert the delivery driver when fluid reaches a certain level in the tank. This will give them enough time to shut off flow.
  • Automatic shutoff devices can stop product flow immediately when the product reaches a certain level.
  • The automatic shutoff valve should not be blocked by anything. Otherwise, an overfill cannot be avoided.
  • Close attention should be paid before, during and after delivery to prevent an overfill.
  • All spills should be reported immediately to the agency.
  • By installing ball float valves, you can slow down the flow of the product. These prevent vapors from exiting the tank when the product reaches a specific level in the tank which alerts drivers.
  • The top of the tanks need to be as tight as possible to prevent vapors from exiting.
  • Only order as much product that can fill 90% of the tank.
By preventing overfill, you can prevent the loss of gallons of valuable product, save time and money which can be best spent elsewhere.
