Introduction to Regulation of
Underground and Above Ground
Storage Tank Systems
Petroleum Storage Tank
Bureau
Our Mission
is to reduce, mitigate and eliminate the
threats to the environment posed by
petroleum products or hazardous material
or wastes released from petroleum storage
tanks.
Underground Storage Tank
(UST)
• Currently regulated by:
– Federal (US EPA 40 CFR)
Underground Storage Tank
Program
– State (NMED 20NMAC5)
Petroleum Storage Tank
Bureau
Aboveground Storage Tank
(AST)
• Currently regulated by:
– Federal (US EPA) currently no one
Federal Regulatory Program
Governing ASTs is active.
HOWEVER, there are existing
statutes & regulations that apply
directly or indirectly to ASTs. So
Federal Reg’s are in the works from
US EPA just like the…
– State (NMED) Petroleum Storage
Tank Bureau, currently in progress
of being created........
NMED REGULATORY BACKGROUND
• Hazardous Waste Act, NMSA 1978
• Ground Water Protection Act, amended, NMSA 1979
• Environmental Improvement Act, NMSA 1979
• Senate Bill 333, Legislative Session, 2001
Aboveground Storage Tank
Regulations
Are being generated with the assistance from
the following:
• Several states with existing regulations governing ASTs
• State NMED PST Bureau Inspector’s experience
• Industry Standards and Codes
 Petroleum Equipment Institute (PEI)
 National Fire Protection Association (NFPA)
 Steel Tank Institute (STI)
 others
Types of
Petroleum Storage Tank Systems:
Underground Storage Tank
Aboveground Storage Tank
Underground Storage Tank
• tanks are constructed of: Steel
• single wall
• double wall
Underground Storage Tank
• tanks are constructed of: Fiberglass
Reinforced Plastic (FRP)
• single wall
• double wall
Underground Storage Tank
• tanks are constructed of a Composite-
steel tank with clad layer
• single wall
• double wall
Aboveground Storage Tank
Field Erected
Aboveground Storage Tank
Shop Fabricated
AST
FieldErected
• various designs and configuration;
• parts are in contact with surface of the ground either: soil
bedding, ringwalls, concrete pads or special foundation.
• usually the underside of the ground contact area not readily
available for visual inspection;
• corrosion damage major concern and other forms of bottom-plate
failures.
• general volumes comprise of large, high-volume/capacity AST,
found at industrial or refining settings (over 50,000 gallons).
AST
ShopFabricated
• various designs and configuration;
• are supported ABOVE the surface of the ground and;
• all parts of tank are readily accessible for visual inspection;
• corrosion damage are of minimal concern;
•general volumes of tanks are under 50,000 gallons.
