SPCC Plan Requirements: Containment, Certification, and Penalties

Federal SPCC plan requirements apply to any non-transportation facility that stores more than 1,320 gallons of oil aboveground, or more than 42,000 gallons underground, in a location where a spill could reasonably reach navigable waters or adjoining shorelines. The rule lives at 40 CFR Part 112, and it obliges you to write a facility-specific Spill Prevention, Control, and Countermeasure Plan, have it certified, keep it current, and follow it every day. Ignoring it can cost tens of thousands of dollars per day of violation, before a drop of oil ever reaches the water.

Does the Rule Apply to Your Facility

The rule reaches onshore and offshore facilities that drill, produce, store, process, transfer, or use oil and could reasonably be expected to discharge it into navigable waters or adjoining shorelines.¹ Two storage thresholds trigger it:

Aggregate aboveground capacity greater than 1,320 U.S. gallons, counting only containers of 55 gallons or more.
Total completely buried capacity greater than 42,000 U.S. gallons, excluding tanks already regulated under the underground storage tank program at 40 CFR Part 280 or an approved state equivalent.

The 1,320-gallon line is lower than most operators expect. A few 275-gallon totes and one 500-gallon diesel tank already clear it. Manufacturing plants, farms, power generation facilities, drilling and production sites, and commercial buildings with backup generators regularly find themselves in scope.

“Oil” under the rule is broad. It covers petroleum, fuel oil, sludge, synthetic oils, mineral oils, and oil refuse, and it also covers animal fats, fish and marine mammal oils, and vegetable oils.² A food plant with bulk cooking oil faces the same rule as a fuel depot. Oil mixed with other wastes (other than dredged material) counts too.³

What Doesn’t Count Toward the Threshold

Several categories are exempt or excluded from the capacity math. Containers under 55 gallons don’t count toward the 1,320-gallon aboveground total.¹ Fuel tanks that power vehicles and heavy equipment are exempt as long as the oil isn’t being transferred or redistributed, though the exemption does not extend to drilling equipment. Residential heating oil at a single-family home is exempt. Buried tanks already regulated under 40 CFR Part 280 are excluded from SPCC capacity calculations. Hot-mix asphalt, pesticide application equipment, and milk and milk-product containers are carved out as well. Even so, if your facility is otherwise subject to SPCC, exempt containers must still be shown on the facility diagram.

What the Written Plan Must Contain

An SPCC Plan is site-specific. There is no generic template that works everywhere. At its core, the plan describes the facility’s layout and includes a diagram marking every fixed oil storage container, every portable-container storage area, transfer stations, connecting pipes, and even exempt buried tanks.⁴

Beyond the diagram, the plan has to address the operational realities of preventing and responding to a discharge:

An analysis of the types of discharges that could occur and the measures that prevent them, including secondary containment, drainage controls, and safe transfer procedures.
A description of the containment and diversionary structures actually installed: dikes, berms, curbing, collection systems, booms, or sorbent materials.
Written inspection and integrity-testing procedures tailored to the facility, with records kept for at least three years.
A training program for oil-handling personnel covering equipment, spill procedures, applicable pollution control laws, and the SPCC Plan itself.
A designated discharge prevention coordinator who is accountable to management.

Secondary Containment

Secondary containment is where facilities most often fall short. The whole system, walls and floor together, has to hold oil so nothing escapes before cleanup.⁴ For bulk storage containers at onshore facilities (other than mobile refuelers), containment must hold the entire capacity of the largest single container plus freeboard for precipitation.⁵ Diked areas have to be “sufficiently impervious” to contain oil, without a specific permeability number in the rule. The certifying engineer or the owner uses good engineering judgment for the products, layout, and site. Sufficiently impervious means the containment holds oil long enough for cleanup, not that it is permanently impermeable.

Who Certifies the Plan and When It Must Be Ready

For most facilities, a licensed Professional Engineer has to review and certify the plan before it takes effect. The PE’s certification confirms the engineer has visited the facility, checked the plan against good engineering practices and industry standards, and found it adequate for the specific operations.⁶ Facility management also has to approve the plan and commit the resources to carry it out.

Timing matters. New facilities other than oil production sites must have the plan prepared and implemented before operations begin. Oil production facilities get a six-month grace period after startup.⁶ You do not file the plan with the EPA. Keep it at the facility, or at the nearest field office if the facility is normally unattended, and make it available during normal working hours.⁷

Qualified Facilities That Can Self-Certify

Smaller, lower-risk facilities can skip the PE certification. The rule creates two self-certification tiers, both capped at 10,000 gallons of aggregate aboveground storage:

Tier I: 10,000 gallons or less aggregate, no single aboveground container larger than 5,000 gallons, and a clean spill history. Tier I facilities can use the simplified EPA template.
Tier II: 10,000 gallons or less aggregate with a clean spill history, but at least one container over 5,000 gallons. Tier II facilities self-certify a plan that meets the full regulatory requirements rather than the simplified template.

The shared spill-history requirement: during the three years before self-certification, no single discharge over 1,000 gallons and no two discharges each over 42 gallons within any 12-month period. Discharges caused by natural disasters, acts of war, or terrorism do not count. If the facility later exceeds 10,000 gallons aggregate or loses its clean record, PE certification becomes mandatory.⁸

Ongoing Compliance

A plan on the shelf is not compliance. The rule expects continuous attention.

Training

Oil-handling personnel must be trained on equipment operation and maintenance, discharge procedures, applicable pollution control laws, and the facility’s SPCC Plan. Discharge prevention briefings run at least annually and cover known spill incidents, equipment malfunctions, and any new precautionary measures.⁴

Inspections and Integrity Testing

Routine inspections of containers, containment structures, and spill prevention equipment follow written procedures set out in the plan itself. The regulation does not impose a universal frequency; the plan sets the schedule based on the facility’s risk profile, with visual checks often daily or weekly depending on volume and spill risk. Bulk storage containers also need periodic integrity testing under recognized industry standards, such as STI SP001 for shop-fabricated tanks and API 653 for larger field-erected tanks. Testing records stay with the plan for at least three years.⁴

Five-Year Review and Amendments

The plan must be reviewed at least every five years. If field-proven prevention or control technology has emerged that would significantly reduce spill risk, the plan has to be updated to incorporate it. Each review requires a signed statement noting whether the plan will be amended.⁹

Between reviews, the plan must be amended whenever a facility change materially affects spill potential. Adding or decommissioning containers, replacing or rerouting piping, altering containment, and changing the product stored are all triggers. Amendments have to be prepared within six months of the change and fully implemented within six months after preparation.⁹

When You Must Report a Spill

If oil actually reaches water, reporting obligations move quickly. You must report a discharge to the EPA Regional Administrator if either threshold is met:

A single discharge of more than 1,000 U.S. gallons of oil to navigable waters or adjoining shorelines.
Two discharges each exceeding 42 U.S. gallons reaching navigable waters or adjoining shorelines within any 12-month period.

These thresholds measure oil that actually reaches the water, not total facility spillage.¹⁰ If containment catches 500 gallons before it leaves the site, this reporting section is not triggered, though the National Response Center has separate obligations for discharges that create a sheen on water. The report to the Regional Administrator identifies the facility, its owner or operator, and its storage capacity.

Penalties for Non-Compliance

Skipping the plan, keeping a bad one, or violating operational requirements exposes a facility to Clean Water Act penalties. The EPA can pursue administrative action or take the matter to federal court. As of the inflation adjustment effective January 15, 2025:

Administrative Class I penalties: up to $23,647 per violation, capped at $59,114 per proceeding.
Administrative Class II penalties: up to $23,647 per day of violation, capped at $295,564 per proceeding.
Judicial civil penalties: up to $59,114 per day of violation, or $2,364 per barrel of oil discharged.
Gross negligence or willful misconduct: a minimum penalty of $236,451, plus up to $7,093 per barrel discharged.¹¹

A facility with no plan at all that stores hundreds of thousands of gallons of oil can see “major noncompliance” settlement demands well above $50,000 before any spill occurs. Once oil reaches water, per-barrel penalties stack and the totals grow fast. Criminal prosecution is possible for knowing violations, though the EPA generally reserves that route for the most serious cases.
