An SPCC plan is a written, site-specific document required by 40 CFR Part 112 that shows how a non-transportation facility will prevent oil from reaching navigable waters and how it will contain a spill if one happens. The SPCC plan requirements apply to onshore and offshore facilities that store, process, refine, transfer, or use oil above set thresholds, and the plan has to be in place before a new facility starts operating. Miss the mark and civil penalties can run up to $25,000 per day.
Does the Rule Apply to Your Facility
Coverage turns on two questions: could a discharge from your site reasonably reach navigable waters or adjoining shorelines, and do you store enough oil to cross a threshold. Proximity to a river is not the test. Stormwater drainage, ditches, and other pathways can bring a site within scope even when open water is not visible from the property.
You need a plan if either capacity threshold is met:
- Aboveground oil storage over 1,320 gallons, counting only containers of 55 gallons or larger.
- Completely buried storage over 42,000 gallons, for tanks not already regulated under 40 CFR Part 280.
Containers under 55 gallons, permanently closed containers, and motive power containers (the fuel tanks that power vehicles and equipment) do not count toward either total.
What Counts as Oil
The definition is deliberately broad. Under Part 112, oil means oil of any kind or in any form: petroleum and fuel oil, sludge, synthetic and mineral oils, oil refuse, vegetable oils from seeds, nuts, fruits, or kernels, and animal fats, fish oils, and marine mammal oils. Cooking oil, hydraulic fluid, and diesel are all in scope if you store enough of them.
Exemptions Worth Knowing
Some oil on your property does not count toward the thresholds. Heating oil at a single-family residence is excluded. So are motive power containers, hot-mix asphalt and its containers, pesticide application equipment and mixing containers, milk and milk-product containers with their associated piping, wastewater treatment facilities used exclusively for that purpose, and buried tanks already regulated under 40 CFR Part 280 or an equivalent state program. The exemptions are narrow. When a container is a close call, the safer decision is to include it in the capacity calculation.
When the Plan Has to Exist
New facilities other than oil production facilities must prepare and implement the plan before beginning operations. There is no grace period to write it after start-up. Oil production facilities get six months from the start of operations to complete their plan.
You do not file the plan with the EPA. You keep it at the facility, available for inspection, at any location that is normally staffed for at least four hours per day. If the site is not regularly attended, you still have to be able to produce the plan for an EPA inspector or during a discharge response.
Who Certifies the Plan
Most facilities need a licensed Professional Engineer to certify the plan before it takes effect. The PE certification is a substantive review. It states that the engineer is familiar with Part 112, that the engineer or a qualified agent has personally visited and examined the facility, that the plan follows good engineering practice and applicable industry standards, that inspection and testing procedures are established, and that the plan is adequate for the facility. Technical amendments require the same certification, which is worth planning for when a facility change is on the horizon.
Qualified Facilities That Can Self-Certify
A smaller facility can skip the PE if it meets every one of these conditions: total aboveground oil storage is 10,000 gallons or less, and in the three years before certification the site has had no single discharge over 1,000 gallons and no two discharges each over 42 gallons in any 12-month window.
Qualified facilities split into two tiers:
- Tier I, where no single aboveground container exceeds 5,000 gallons. These facilities can complete and self-certify the EPA template in Appendix G to Part 112 rather than draft a full plan.
- Tier II, where at least one aboveground container exceeds 5,000 gallons but the site still meets the 10,000-gallon total and the clean-discharge history. These facilities prepare a full self-certified plan meeting every applicable requirement, but without a PE signature.
Self-certification carries the same liability as any other plan. If an inspection or a spill exposes a deficiency, the owner answers for it.
What the Plan Must Cover
The plan is a site-specific technical document, not a general policy statement. It describes the equipment, procedures, and engineering controls the facility uses to keep oil out of water.
Secondary Containment
Every bulk storage container installation other than mobile refuelers must have secondary containment sized to hold the entire volume of the largest single container on site, with enough freeboard to absorb rainfall without overtopping. That usually means dikes, berms, or double-walled construction engineered to that worst-case volume.
Facility Drainage
The plan has to spell out how stormwater is managed and how oil is kept out of drainage systems. Run-on from adjacent areas has to be controlled, and drainage from oil storage and handling areas cannot flow into storm sewers or waterways without appropriate containment or treatment.
Loading and Unloading Racks
Racks that handle tank cars or tank trucks need drainage systems or catchment basins sized to hold the largest single compartment of any vehicle using them. The plan must also include physical safeguards against a vehicle pulling away with lines still connected: interlocked warning lights, barriers, wheel chocks, or brake interlocks. Before a loaded vehicle leaves, the lowest drain and all outlets have to be inspected.
Security
The plan describes how access to oil handling and storage areas is controlled, how master flow and drain valves are secured, how unauthorized pump operation is prevented, and how out-of-service pipeline connections are locked. Lighting has to be adequate both to deter vandalism and to help detect a discharge. The regulation lets the owner choose the specific measures, but the plan has to address each area.
Integrity Testing
Each aboveground container must be tested or inspected for structural integrity on a regular schedule and after any material repair. Testing frequency and methods are set from industry standards, taking container size, design, and configuration into account. STI SP001 typically governs shop-fabricated aboveground tanks under 50,000 gallons; API 653 governs large field-erected welded tanks. The plan documents which standard applies, the inspection method, the interval, and where the records live. Supports and foundations get inspected, the exterior is checked frequently for deterioration, and diked areas are checked for oil accumulation. Comparison records for each container are kept under normal business practices.
Keeping the Plan Current
The Five-Year Review
You must review and evaluate the plan at least once every five years from the date the facility became subject to the rule. If field-proven prevention or control technology has become available that would significantly reduce discharge risk, the plan must be amended within six months and the amendment implemented within another six months. Even when nothing changes, the review has to be documented with a signed statement of the date and the decision not to amend.
Amendments After Facility Changes
Any change in design, construction, operation, or maintenance that materially affects discharge potential triggers its own amendment obligation, separate from the five-year cycle. Adding or removing containers, replacing or relocating piping, modifying secondary containment, switching the product stored, or revising standard operating procedures are all common triggers. The amendment is prepared within six months and implemented within six months after that. Technical amendments need PE certification unless the facility qualifies for self-certification.
Training
Everyone who handles oil must be trained on equipment operation and maintenance, discharge response procedures, applicable pollution control laws, general facility operations, and the contents of the SPCC plan. On top of that initial training, an annual discharge prevention briefing is required. Those briefings have to highlight known discharges or equipment failures and cover any new precautionary measures the facility has adopted.
Inspections and Records
Container inspection frequency is whatever the plan sets under the applicable industry standard, not a fixed calendar. Integrity testing records are kept for at least three years and should show the inspection date, the inspector’s qualifications, the method used, the findings, the pass/fail determination, any repairs, and the next scheduled inspection date. Training records document dates, attendees, and topics.
Reporting a Discharge
If a discharge occurs, the person in charge of the facility must notify the National Response Center immediately after learning of it. Immediately means immediately; there is no built-in window for investigation. The NRC line runs 24 hours a day at 1-800-424-8802. Failing to report is a criminal matter, and conviction can bring fines under Title 18 and up to five years of imprisonment.
Penalties
The Clean Water Act gives the EPA two enforcement paths. Administrative penalties are assessed directly: Class I reaches $10,000 per violation up to a $25,000 total, and Class II reaches $10,000 per day up to $125,000. Those are the base statutory figures, and they are periodically adjusted for inflation.
Judicial penalties run higher. A discharge in violation of the law exposes a facility to civil penalties of up to $25,000 per day of violation or $1,000 per barrel discharged. Where the discharge resulted from gross negligence or willful misconduct, the minimum climbs to $100,000 and the per-barrel cap rises to $3,000. Failing to comply with the SPCC regulations themselves carries a separate civil penalty of up to $25,000 per day, with no spill required. Inflation adjustments push the effective maximums above the base numbers.
Set against those figures, the cost of a properly certified plan, containment engineered to the largest tank on site, and an annual training briefing is the cheaper path by a wide margin.
