What is an OPD?
- All new tanks are to be manufactured with overfill protection devices (OPDs).
- Tanks without OPDs can no longer be refilled by anyone.
- Empty tanks with round or star shaped valve hand wheels do not contain OPDs and are obsolete.
- OPD tanks can be identified by the unique triangular shape of the valve's handwheel.
- They also have the letters "OPD" on the hand wheel and the side of the valve.
