Here's what I got from the EPA. I was partially correct.
In 1973, EPA issued the Oil Pollution Prevention Regulation, which is codified at 40 CFR Part 112 (PDF download, 576K, 72 pages) Abstract, to address the oil spill prevention provisions contained in the Clean Water Act of 1972. The regulation forms the basis of EPA's oil spill prevention, control, and countermeasures, or SPCC, program, which seeks to prevent oil spills from certain aboveground and underground storage tanks. In particular, the regulation applies to non-transportation-related facilities that:
* Have an aboveground storage capacity of more than 660 gallons in a single tank, an aggregate aboveground storage capacity of more than 1,320 gallons, or a total underground storage capacity of 42,000 gallons; and
* Could reasonably be expected to discharge oil in harmful quantities into navigable waters of the United States.
My recommendation would be to review what you do and why you do it. Reduce the amount of spillable material that you maintain. If you don't need it, get rid of it!
You'de be surprised what a process review will reveal and how potential impacts can be reduced.
I guess I've provided you with an Objective for an Aspect "Reduce the potential for spillage and the requirement for an SPCC" Now you come up with the Target
