May 2, 2023

• Increasing trends in tank (mobile & stationary) overfill occurrences.

• 2014: One Incident• 325 BBL Vac Trailer balled out. Both employees (two (2) person transfer) left rear

doghouse during a mineral oil fluid transfer. • Impact# 12816 Corrective Action “New Tankers coming into field this year will be equipped

with overfill protection gauges that will shut loading valve. Fleet will be retro-fit based on the performance of these units”.

• 2015: Two Incidents:• 100 BBL Fuel Truck overfilled with diesel releasing it into spilldam and rear doghouse of

the tanker (by design).• 238 BBL Diesel Transport overfilled releasing 30 gallons of diesel out of rear mounted

trailer vent. Trailer was not level, nose high, loosing 25 BBL of displacement.• 2016: One Incident:

• 325 BBL Crude Hauler overfilled releasing 5 gallons of crude oil

Factors Leading to Implementation

2

• New infrastructure regulations established in International Fire Code 3406.5.1.10-3406.5.1.10.1

• 3406.5.1.10 Bottom Loading:• When bottom loading a tank vehicle or tank car with or without vapor control, a

positive means shall be provided for loading with an automatic secondary shutoff control to prevent overfill. The connecting components between transfer equipment and the tank vehicle or tank car required to operate the secondary control shall be functionally compatible.

Spillage is prevented when filling a bottom-loading tank vehicle by using a loading system that loads a predetermined quantity of flammable or combustible liquid. An automatic secondary shutoff control valve is required for a bottom-loading tank vehicle.

• 3406.5.1.10.1 Dry Disconnect Coupling:• When bottom loading a tank vehicle, the coupling between the liquid loading hose or

pipe and the truck piping shall be a dry disconnect coupling.To prevent spillage when disconnecting the dispensing system from the bottom-loading

vehicle, the system is to use a dry connection.

In Closing – New Technology Opportunities

• With new technology comes the opportunity for continuous business improvements. We must keep this in mind during all stages of design for our infrastructure and core equipment.

• Learn from perceived failures and seize the opportunities to learn and adapt. Some times the answer is right in front of us.• Alpine introduced Over-Fill Warning Systems to the field in 2010, but failed to

research the technology for all Tankers/100BBL Trucks.• By 2014 personal changes allowed this system to be forgotten and research had

to be repeated.

May 2, 202325

In Closing – Learn and Adapt

• The Titan Logix® system has proven to be a more reliable system.• The SeeLevel™ Gauge has limitations due to design as a float gauge.

• Fluid movement in tank allows float to active Overfill Warning during transport.• Dependent on the cleanliness of the 325BBL Vac Trailer Alpine has experienced

floats sticking and not measuring fluid levels correctly.
