purpo se

  • most industrial facilities utilize storage tanks in some

capacity capacity

  • Federal and State regulations may apply to each tank
  • regulations are vastly different

regulations are vastly different

  • permit holders cannot assume that compliance with
  • ne regulation applies to others
  • regulations can be confusing, hard to find, and may

not be included in facility permits

  • compare the go erning bodies’ reg lations
  • compare the governing bodies’ regulations
  • identify key differences to help facilities achieve and

document compliance with each regulation document compliance with each regulation

F ederal SPCC (40 CF R part 112)

  • purpose is to prevent oil discharges from

pu pose s to p e e t o d sc a ges

  • reaching navigable waters or adjoining shorelines
  • applies to any facility over capacity threshold

pp y y p y

  • any facility handling oil that could reasonably be

expected to discharge oil into navigable water

  • applies to tanks containing oil (petroleum or non)
  • requires a written SPCC Plan
  • MOST USTs fall under a separate regulation (40

CFR part 280) only requirement is to label on map
