Definition of Oil Spill Prevention (SPCC Plan)

A Spill Prevention, Control, and Countermeasure (SPCC) plan is a written plan required by the U.S. Environmental Protection Agency under 40 CFR Part 112 for facilities that store oil and could reasonably be expected to discharge it into navigable waters or adjoining shorelines. The plan describes the facility's oil storage, the equipment and practices used to prevent spills, secondary containment, inspections, training and how the facility will respond if oil is released.

Key Facts About SPCC Plans

  • The rule applies when aggregate aboveground oil storage capacity exceeds 1,320 gallons, counting containers of 55 gallons or more, or completely buried capacity exceeds 42,000 gallons.
  • "Oil" includes fuels, lubricants, hydraulic oil, vegetable oils and animal fats.
  • Most plans must be certified by a licensed Professional Engineer, but smaller "qualified facilities" may self-certify.
  • Plans must be reviewed at least every five years and amended when changes affect spill potential.
  • Requirements include secondary containment, regular inspections, employee training and spill response procedures.

Example of an SPCC Plan

A construction equipment yard stores diesel in two 1,000-gallon aboveground tanks. Because total capacity exceeds 1,320 gallons and a nearby creek could be affected, the company prepares an SPCC plan, installs double-walled tanks, stocks spill kits, and trains fueling staff on inspection and response.

What an SPCC Plan Includes

  • A facility diagram showing oil containers and drainage
  • Container inventory and storage capacities
  • Secondary containment and spill containment measures
  • Inspection, testing and recordkeeping procedures
  • Personnel training and discharge prevention briefings
  • Spill response and notification procedures

Frequently Asked Questions: SPCC Plan

Does my facility need an SPCC plan?

You likely need one if you store more than 1,320 gallons of oil above ground in containers of 55 gallons or more and a spill could reasonably reach a waterway, including through storm drains or ditches.

Who can certify an SPCC plan?

A licensed Professional Engineer certifies most plans. Qualified facilities, generally those with 10,000 gallons or less of aboveground capacity and a clean spill history, may self-certify.

How often must an SPCC plan be updated?

At least every five years, and whenever changes in design, construction, operation or maintenance materially affect the facility's potential to discharge oil.
