6. Required Operator Training
The federal law divides UST operators into three
classes based on their duties.
 Each UST facility must have a designated Class A, B, and C operator.
 Each operator will be required to pass a test to become certified.
 Class A and B operators must be trained and certified through an
Ecology-approved training program.
 Class C operators may obtain their certification through an Ecologyapproved training or by the UST facility’s certified Class A and/or B
operator (s).
If your UST system is found to be out of compliance, the Class A ,B or C
operator may be required be re-trained on any or all UST regulations.

7. Operator Class Definitions
Class A
 Owners and employees who have primary responsibility to
operate and maintain UST systems
 Qualified to train Class C operators
Class B
 Operators that are responsible for day to day
operations, maintenance, and record keeping for UST
 Must have in-depth understanding of all operations and
maintenance of UST
 Qualified to train Class C operators
Class C
 Operators on site daily who generally responds to alarms and
emergencies due to spill and release from UST
 Employees who are responsible for the dispensing or sale of
product
Proof of training must be kept readily available and include the UST
operator’s name or the employee’s name, the date training was
completed, and the name, address, and facility ID number of the
facility the operator serves. At least one trained operator must be on
site during hours of operation.

8. UST Operators
 Facility owner or individual designated by the owner
 Control of or responsibility for the operation and maintaining of the UST
system
 Ensures that the system is in compliance with all federal and state
regulations
 Received a certificate of compliance showing completion of a training
program from an authorized vendor

their employees are properly certified.

11. Stage I, II Overview
This information falls under Air Quality and not part of UST regulations.

12. Vapor-Recovery System
Stage I
Stage II
The UST includes a vapor recovery system to prevent vapors from being
released into the air. In Stage I, vapor is returned to the truck during delivery.
In Stage II, vapor is captured from the car’s fuel tank by the dispenser nozzle
and returned to the UST.

13. UST Stage I
This drawing represents a typical Underground Storage Tank system. The purple
pipes represent vapor-recovery systems, and the orange represents product.
The red box is the turbine which sends the fuel to the dispenser.

14. Stage I
One hose delivers product to the UST
while the other returns vapor to the truck.

15. Stage I Tank Field
The large round lids are access ports for tank maintenance. This
should be handled by certifiedprofessionals.

16. Stage I Fill Sumps
The smaller lids pictured here are fill sumps, which are access holes through
which USTs are filled. Facility employees may access these sumps for basic
maintenance, remove water and clean out debris, check tank product
level, and check for cracks. Any cracks or poor installation found that release
fuel into the environment requires repair or replacement.

17. Stage II: Balance System
 In areas where a rubber boot is required on the nozzle,
make sure the boot is free from cracks, cuts, or holes.

18. Stage II: Vacuum-Assist Nozzle

19. Stage II: Vacuum-Assist Nozzle
Vacuum-assist nozzles return vapors to the
UST and are typically used in areas where
a balance system is not required.
(Check with your local Air Quality
Department to determine which kind of
equipment your facility should use, in
some cases this could be the state)
