Petroleum Storage Tank Bureau
Our Missionis to reduce, mitigate and eliminate the
threats to the environment posed by petroleum products or hazardous material or wastes released from petroleum storage
tanks.

• Currently regulated by:– Federal (US EPA 40 CFR)
Underground Storage Tank Program
– State (NMED 20NMAC5) Petroleum Storage Tank Bureau
• 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........
Underground Storage Tank (UST)
Aboveground Storage Tank (AST)

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

ASTField-
Erected
• 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).

ASTShop-
Fabricated
• 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.
