Overfill Prevention
Check type of system. / System alerts transfer operator when tank is 90% full by restricting flow into tank or triggering an audible and visual alarm. Does not allow for manual override.
External alarm OR
Flow Restrictor / System provides positive shut-off of flow to tank when tank is filled to no more than 95% of capacity. Does not allow for manual override.
Fill tube valve/flapper / System restricts delivery of flow to tank at least 30 minutes before tank overfill. Does not allow for tank override. Flow restriction occurs when tank is 95% of capacity, and activates audible alarm five minutes before tank overfills.
Ball float valve and external alarm. / System provides positive shut-off of flow to tank so that none of the fittings located on top of the tank are exposed to product due to overfilling. Does not allow for manual override.

Training
Describe training program for UST operators/owners.
State Certified owner/operator training program –REQUIRED
Training conducted by UST service provider/manufacturers representatives.
Training provided by on-the-job-training.
Training provided by
Training plan is attached. / Certify by signing that this has been completed. / Date completed.
Facility personnel with UST monitoring responsibilities have been familiarized with all aspects of monitoring the tank system at this facility and are familiar with the laws and regulations.
Personnel responsible for maintaining UST monitoring records (i.e. logs, test reports, etc. 0 have been instructed that most records must be maintained on site for a minimum of three years, and some for 61/2 years.
Personnel responsible for performing visual or other inspections are trained to document inspections in a thorough manner. They are trained to distinguish proper equipment function, in proper procedures for reporting alarms, leaks equipment failure, and other problems.
Certification
I have reviewed this Underground Storage Tank Monitoring and Response Plan and have determined that it accurately describes monitoring of the designated underground storage tanks at this facility.
