SPCC FAQs


1. What regulation does the SPCC rule fall under?

The SPCC requirement falls under the Oil Pollution Prevention regulation (40 CFR Part 112). The Oil Pollution Prevention regulation also houses the Facility Response Plan requirement. For more information on whether your site requires a Facility Response Plan, click here.

2. Do I fall under the SPCC rule?

Facilities that store, process, refine, use or consume oil or oil products & do not participate in the transportation fall under the SPCC rule if:

  • There is a “reasonable expectation of an oil discharge” to navigable waters

AND if you satisfy one of the following:

  • You have greater than 1,320 gallons of total aboveground oil capacity
  • You have greater than 42,000 gallons of total underground oil capacity
3. What do I need to do if I fall under the SPCC rule?

You must prepare and implement an SPCC plan.

4. What are the requirements for the SPCC plan?

Describe the physical layout of the facility and include a facility diagram

  • Container/Associated piping
  • Transfer stations (i.e., fueling islands)
  • Must mark the location and contents of each
Address/Describe the following:
  • Oil type & storage capacity of all applicable containers
  • Discharge prevention measures
  • Discharge or drainage controls
  • Countermeasures for discharge discovery, response, and cleanup
  • Procedures to follow in case of a discharge
5. How often do I update my SPCC Plan?

You must update your SPCC plan every five years or when changes are made to the facility.

6. What types of oil are covered under SPCC?

All types of oil and oil products are covered under SPCC. These range from motor oil all the way to vegetable oil. Some more examples include:

  • Diesel
  • Olive Oil
  • Grease
  • Avocado Oil
  • Fuel Oil
  • Used Oil
  • Animal Fats
  • Gasoline
7. Does a licensed Professional Engineer (P.E.) need to certify my SPCC plan?

Yes, you do need a licensed P.E. to certify your SPCC, unless you meet the criteria to self-certify. 

8. What are the criteria to self-certify my SPCC plan?

If you meet the following criteria, the facility owner or operator may self-certify their SPCC plan:

  1. Total aboveground oil storage capacity of 10,000 gallons or less, and
  2.  In the 3 years prior to the date the SPCC plan is certified, the facility has had no single discharge of oil to navigable waters or adjoining shorelines exceeding 1,000 gallons, or no two discharges of oil to navigable waters or adjoining shorelines each exceeding 42 gallons within any 12-month period.

If you do not meet the criteria to self-certify specified above, the SPCC plan must be certified by a licensed Professional Engineer (P.E.).

9. What is the difference between a bulk storage container and oil-filled equipment?

Bulk storage containers are containers that are solely used to store oil (i.e., AST's, drums, totes), whereas, oil-filled equipment has an oil storage container(s) to support the function of the device (i.e., Transformers. hydraulic systems, circuit breakers).

10. Do I need to do any inspections for SPCC?

Yes, you do have to do inspections for SPCC.

11. What do I need to inspect?

You will need to inspect SPCC applicable bulk storage containers associated piping/valves for damage, corrosion, leaks, and functionality, as well as, secondary containment for completion and functionality.

XXXXX also recommends that the following items also be inspected as best practices:


  • Oil-filled equipment for leaks, damage, corrosion and functionality
  • Proper sizing of secondary containment and secondary containment is free of debris
  • Valves and storage containers themselves are closed completely
  • Surrounding soil/flooring for any indication of oil
  • Any spill kits on-site are complete with all required elements
12. When do I perform inspections?

The frequency at which you perform your SPCC inspections will be stated in your SPCC plan. It is best to follow the manufacturer's inspection schedule, but if those are not available, the industry standard is to perform inspections monthly.

13. When do I use general secondary containment?

At a minimum, all areas with the potential for an oil discharge require general secondary containment.
These areas may include:

  • Bulk storage containers
  • Mobile/portable containers
  • Mobile Refuelers
  • Oil-filled equipment
  • Loading/unloading areas

For more examples, click here and reference section 4.2.

14. What are some examples of general secondary containment?
  • Dikes
  • Curbing
  • Gutters
  • Retention ponds
  • Sorbent Materials
15. When do I use sized secondary containment?

Sized secondary containment is required in the following areas:

  • Loading/unloading racks
  • Bulk storage containers
  • Production facility bulk storage containers
16. How do I "size" my secondary containment?

Sized secondary containment must be designed to contain the capacity of the bulk storage container plus appropriate freeboard for precipitation. The industry standard has been to have the capacity of 110% of your total bulk storage container capacity.

17. What do I do if I have stormwater in my secondary containment?

If you have stormwater in your secondary containment, you may be able to dispose of it as stormwater. First, you must complete a bermed release form. A bermed release form will ask whether you can spot the presence of oil in the water. If there is no sign of oil, you may release it as stormwater, but if there is a sign of oil, you will need to dispose of the water as oil waste and investigate the origin of the oil. 

18. If I have a spill, who do I call?

If a reportable quantity was released off-site, call the National Response Center at (800) 424-8802.

If the spill is 1,000 gallons or more or if there are two oil spills of 42 gallons or more in a 12-month period, call the US EPA Spill Hotline at (800) 300-2193.

You may need to contact local and/or state-specific agencies regarding oil spills, as well. Please refer to your SPCC plan for that contact information and the circumstances in which you will need to contact them.
