Regulation Changes
• Federal Rule Based Changes
– Federal Regulations finalized in July 2015
– Federal Rules effective October 2015
• State Rule
– Finalized and effective May 30, 2017
– Many state specific deadlines are later than
federal rule
EPA Compliance Dates ≠ Missouri Compliance Dates

New Installations
• Reduce notification from 30 to 14 days
• Post-installation testing options
– Tank and Line Tightness Test
– 0.1gph certified Automatic Tank Gauge (ATG)
test with tank 95 percent full
• Testing overfill, spill and sumps at install
– For new installs after July 1, 2017

UL1856 - The New Lining Standard
1. Lining: single-walled, traditional testing
2. Upgrade: double-walled
– Requires original “host” tank integrity
3. Self-structural: double-walled
– Does NOT require original “host” tank
integrity

Lining Inspection Options
• Standard Five Year Inspection
• OR Interstitial Monitoring
– If double-walled lining
– May use interstitial monitoring
– Must have 12 months interstitial monitoring
records

Secondary Containment
• New (including replacement) tanks only
• Piping replacement (50 percent or more of
a piping system within one year)
• Does not apply to existing systems (until
replaced)
Effective July 1, 2017
![Page 12: Ust rules changes - tankapedia.com · TANK RULE CHANGES Heather Peters UST ... EPA Compliance Dates ≠ Missouri Compliance Dates. New Installations ... Key Dates to Remember …](https://reader034.fdocuments.us/reader034/viewer/2022051801/5ae653777f8b9a8b2b8d204a/html5/thumbnails/12.jpg)
Secondary Containment (cont.)
• Double-wall tanks
• Double-wall piping
• Containment sumps
• Interstitial monitoring the system
Does not include spill basins or vent piping
![Page 13: Ust rules changes - tankapedia.com · TANK RULE CHANGES Heather Peters UST ... EPA Compliance Dates ≠ Missouri Compliance Dates. New Installations ... Key Dates to Remember …](https://reader034.fdocuments.us/reader034/viewer/2022051801/5ae653777f8b9a8b2b8d204a/html5/thumbnails/13.jpg)
50 Percent Piping System
Replacement
• Within 12 month period
• For a piping system
– Single tank’s piping (single product)
– Not of the total site piping
– Do not combine same products unless piping
is manifolded
Entire piping system must be double-walled with
containment sumps and monitoring
![Page 14: Ust rules changes - tankapedia.com · TANK RULE CHANGES Heather Peters UST ... EPA Compliance Dates ≠ Missouri Compliance Dates. New Installations ... Key Dates to Remember …](https://reader034.fdocuments.us/reader034/viewer/2022051801/5ae653777f8b9a8b2b8d204a/html5/thumbnails/14.jpg)
Old piping = 250 feet
New piping = 350 feet
Over 50 percent of the piping project was new. Therefore EVERYTHING would
have to be double-walled with containment sumps, even existing portion of
piping/dispenser system.
Proposal: Tie into existing piping to add diesel to
“auto” side of the building
![Page 15: Ust rules changes - tankapedia.com · TANK RULE CHANGES Heather Peters UST ... EPA Compliance Dates ≠ Missouri Compliance Dates. New Installations ... Key Dates to Remember …](https://reader034.fdocuments.us/reader034/viewer/2022051801/5ae653777f8b9a8b2b8d204a/html5/thumbnails/15.jpg)
If Completed as Proposed:
Old piping = 250 feet
![Page 16: Ust rules changes - tankapedia.com · TANK RULE CHANGES Heather Peters UST ... EPA Compliance Dates ≠ Missouri Compliance Dates. New Installations ... Key Dates to Remember …](https://reader034.fdocuments.us/reader034/viewer/2022051801/5ae653777f8b9a8b2b8d204a/html5/thumbnails/16.jpg)
Alternative Suggestion:
Old piping = 250 feet
New piping = 350 feet
Add a NEW submersible turbine pump to create a NEW piping run/system on
existing tank. NEW piping run must meet new requirements. Old piping remains
unchanged.

• Based on individual tank
systems
• Does not matter how
many different
systems/products are
beneath the dispenser
• May have to install
containment sumps under
dispensers with other
piping runs entering

• Manifold piping (all
connected) counts as a
system
• Even if only affects one
“half” of the manifold, all of
the connected piping must
comply
• Includes sumps at each
end and transition

Piping and Sumps
• Double-walled piping
– Open to containment sump
• Fittings, valves, transitions, connectors or
any other single-walled piping must be in
a containment sump

Things to Consider for New Sumps
• Number of sump penetrations
• Location of sump penetrations
• Types of containment sumps
• Entry boots - type and installation
• Seal all electrical conduits well
• Keep the sumps clean and free of product

Low-Level Sump Testing
✓Approved in Missouri IF:
✓Sensors are installed at low point
✓Sensors are properly installed (manufacturer’s
instructions
✓Sensors will detect liquid ingress
✓Liquid alarm triggers SHUTDOWN of
submersible turbine pump(s) (STPs)
associated with that sensor
✓If dispenser sensor alarms - must shutdown ALL
products in that dispenser
