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.

Petroleum Storage Tank Bureau
Underground Storage Tank (UST)
Aboveground Storage Tank (AST)

• 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 Regs are in the works from US
  EPA just like the
• State (NMED) Petroleum Storage Tank Bureau,
  currently in progress of being created........

• AST
• Field-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).

13
Petroleum Storage Tank Bureau

• AST
• Shop-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.
