What is a UST?What is a UST? 10% or more of its volume (including
piping) is underground Holds petroleum product or hazardous
material Also includes holding tanks serving floor
drains

slide 4
Why regulate USTs?Why regulate USTs? Small leaks of petroleum products or hazardous materials from USTs can contaminate
large groundwater supplies
Leaks can also create health and fire hazards in nearby buildings

UST RegistrationUST Registration USTs storing fuel oil for heating
commercial facilities must be registered with DEM - including schools
Commercial USTs storing motor fuel or hazardous materials must also be registered– includes waste oil USTs– includes holding tanks serving floor
drains

UST Registration UST Registration (cont’d.)(cont’d.)
Annual fee- $50 per tank (municipalities exempt); DEM issues annual certificate
Application provides information on tank system age, construction, contents and ownership

Existing System Existing System Requirements-Requirements-Spill ProtectionSpill Protection Spill containment required on all
registered USTs since January 1, 1993– three gallon capacity– above-ground fills exempt

slide 9
Existing System Existing System Requirements- Leak Requirements- Leak DetectionDetection Leak detection is not specifically required for
USTs holding heating oil for on-site consumptive use
DEM recommends periodic tightness testing, and other inventory controls, as good management practices– DEM licenses testers and approves test methods
All releases must be reported immediately to DEM, the local water supplier (if sensitive area), and the local fire authority
RI DEM/Office of Technical and Customer Assistance
slide 10
Existing System Existing System Requirements- Requirements- Abandonment ProhibitionAbandonment ProhibitionAbandonment means the relinquishment
or termination of possession, ownership or control of USTs, by vacating or by disposition, without meeting the closure requirements...; or the action of taking a UST or UST system out of operation for a period of greater than 180 consecutive days without the prior permission of the Director...
No UST may be abandoned- there are no exceptions
Extensions may be granted on a case-by-case basis (temporary closure)

Requirements-Requirements- Tank Tank ClosureClosure
Closure of commercial tanks must be pre-approved by DEM– $75 application fee
DEM conducts inspection of excavation– must schedule closure inspection
Residues must be managed appropriately– must be transported off-site by permitted hazardous
waste transporter Tank must be cut/cleaned per Fire Marshal’s regulations Closure Assessment only required for motor fuel USTs Closures-in-place only approved under special conditions
RI DEM/Office of Technical and Customer Assistance
slide 12
New Installation New Installation StandardsStandards Application must be submitted to DEM
Must be approved before installation
New UST facilities may not be constructed in wellhead protection areas (replacement tanks are allowed)
Substantial modifications of UST systems must also be pre-approved
USTs serving floor drains have special requirements
RI DEM/Office of Technical and Customer Assistance
slide 13
New Installation Standards New Installation Standards (cont’d.)(cont’d.)
Tanks must be double-walled, steel tanks must have corrosion protection
Piping must be double-walled, with containment sump
UL or ULC listed, National Codes of Practice
Entire system precision tested upon installation
Spill containment and overfill protection required
RI DEM/Office of Technical and Customer Assistance
slide 14
General Approval ProcessGeneral Approval Process Submit scope of work to DEM thirty
(30) days in advance Written approval from DEM required
prior to commencement of work (including product piping replacement)
Notify DEM 48 hours prior to installation
Written verification of completion within fifteen (15) days
RI DEM/Office of Technical and Customer Assistance
slide 15
Installation PaperworkInstallation Paperwork completed registration application detailed site plan (plans for new facilities
require PE stamp) including location of:– all tanks and piping– dispensing units– groundwater monitoring wells– water table elevation– public water supply wells or reservoirs within 400’– facilities served by private wells within 200’– proposed and existing buildings and associated
structures– boundaries of the facility– north arrow
RI DEM/Office of Technical and Customer Assistance
slide 16
Installation Paperwork Installation Paperwork (cont’d.)(cont’d.) Cross-sectional view of the tank
– depth of excavation– bedding thickness– backfill depth– supports and anchorage used– dimensions and thickness of traffic pad
Equipment list and written description– tank(s)– piping– leak monitoring systems– spill/overfill protection methods– corrosion protection methods– operation and maintenance requirements for any of the above
RI DEM/Office of Technical and Customer Assistance

UST Professional UST Professional CertificationCertification
Individuals who conduct precision tests must now be licensed by DEM
Installers must be licensed by RI Dept. of Labor/Division of Professional Regulation, and certified by applicable equipment manufacturers
DEM encourages voluntary efforts by UST installers, removers, and corrosion protection experts to obtain certification from a non-profit testing agency- the International Fire Code Institute– we hope to make this certification mandatory
Self-Audit ChecklistSelf-Audit Checklist Are all your USTs registered?
check DEM registration database make sure registration fees are paid in full
Make sure required documentation is submitted spill containment installation notices
Plan for replacement remove/replace (old) tanks evaluate new storage technology- UST vs AST
Gasoline or generator fuel USTs? Leak detection, 1998 upgrade requirements, and others apply
RI DEM/Office of Technical and Customer Assistance
slide 19
What about above-ground storage tanks?– ASTs are regulated by DEM– Installations are approved by local authorities
What about the 1998 upgrade requirements?– These only apply to motor fuel USTs, and fuel
oil distribution USTs.
What about financial responsibility?– This is only required for motor fuel USTs, and
fuel oil distribution USTs.
