7 DE Admin Code 1124.27
Gasoline tanker truck owners and operators are subject to delivery vessel permitting and testing requirements. The regulations ensure that tankers delivering to gasoline stations with Stage I controls are vapor controlled and vapor tight.
Each year, owners are required to:
- Have each tanker truck tested for vapor-tight integrity
- Submit the test results to DNREC
DNREC will review the test results to ensure vapor-tight compliance and issue a permit for each tanker. The permit is in letter form, and explains all regulatory conditions for tankers to meet Stage I requirements. A copy of the permit must accompany each tanker truck delivery vessel.
Gasoline tanker trucks must also display a sticker near the DOT Certification plate that:
- Shows the date the truck last passed the vapor-tight integrity test
- Shows the identification number of the truck tank
- Expires not more than 1 year after the date of the integrity test
Hatches on the tanker truck must be closed at all times except during measurement of the product level or during maintenance. ...
