When and How to Update Your SPCC Plan

If your Spill Prevention, Control, and Countermeasure plan is sitting in a binder somewhere on site, two questions matter: when does the regulation require you to review it, and what changes at your facility require an amendment before the next scheduled review? Federal SPCC rules under 40 CFR Part 112 set both deadlines, and missing either can put you out of compliance even if the binder is full of pages.

This piece covers what triggers an SPCC plan update, how the review cycle works, and what an update actually involves. For the broader picture of who needs an SPCC plan and how the service works in California, see our SPCC plan development and certification services in California guide.

How Often Must the SPCC Plan Be Reviewed?

Under 40 CFR 112.5, every facility with an SPCC plan must complete a full review of the plan at least once every five years. The review can end one of two ways. Either the plan still reflects the facility as it stands, you sign and date the review attestation, and the clock restarts. Or you find changes that require an amendment, in which case the plan must be updated and the amendment certified by a California-registered professional engineer (for PE-certified plans).

The five-year clock runs from the date of the last review, not the date the plan was originally written. A plan that was reviewed in 2021 needs another documented review by 2026, whether or not anything has changed.

Reviews are documented on the Record of Revision page near the front of a standard SPCC plan. Each entry shows the date, who reviewed the plan, and whether changes were made. Inspectors look at this page first to confirm the plan has actually been maintained.

Changes That Require an Amendment Before Five Years

The five-year review is a backstop. The SPCC rule also requires you to amend the plan whenever a change at the facility materially affects the facility’s potential for a discharge. When such a change occurs, the SPCC Plan must be amended and the amendment implemented as soon as possible, but not later than six months after the amendment is prepared (40 CFR 112.5). You don’t wait for the next scheduled review.

The triggers we see most often:

• Adding or removing oil storage containers. New backup generator with a base tank. Replacing a 1,000-gallon waste oil drum array with a 2,000-gallon tank. Removing an obsolete transformer. Anything that changes total aboveground oil capacity or the configuration of storage.
• Changes to secondary containment. New berms, replaced dikes, drainage system changes, new sumps, anything that alters how a spill would be contained.
• Changes to transfer operations. New loading or unloading area, new piping, revised transfer procedures, changes to where oil enters or leaves the facility.
• Ownership change. A new owner inherits the SPCC plan but must amend it to reflect the new responsible party and any operational differences.
• Facility expansion. New buildings, new pavement, new spill pathways that didn’t exist when the plan was last written.
• A spill or release event. Any discharge that reaches navigable waters, or that exceeds reporting thresholds, requires the plan to be reviewed against the cause and amended to prevent recurrence.

Routine maintenance does not trigger an amendment. Replacing a gasket on existing piping is not an amendment. Adding a 500-gallon AST is. When in doubt, the test is whether the change affects the facility’s potential to discharge oil.

Decision Checklist: Is Your Plan Due for an Update?

Run this against your facility right now:

1. Has it been five years since your last documented review? → Yes: Review required.
2. Has any oil storage container been added, removed, or relocated since the last review? → Yes: Amendment likely required.
3. Has secondary containment been modified, added, or removed? → Yes: Amendment likely required.
4. Has the facility had an ownership change? → Yes: Amendment required.
5. Has there been any oil spill or release, even a small one? → Yes: Review the discharge against the plan; amendment may be required.
6. Are monthly visual inspections and annual comprehensive inspections being performed and documented? → No: The inspection program needs to be set up, even if the plan itself is current.

If you answered yes to questions 1 through 5, the plan needs work before your next inspection. If you answered no to question 6, the plan may technically be current, but you are not implementing it, which is its own deficiency.

Reviews, Amendments, and Inspections Are Three Different Things

These three terms get used interchangeably, and they shouldn’t be:

• Five-year review. Required by 40 CFR 112.5. A scheduled, documented walk-through of the plan against the facility. If nothing has changed, the review is signed off and the plan stands. If things have changed, an amendment follows.
• Amendment. A change to the plan content. Triggered by facility changes (see above) or by issues identified during a review. PE-certified plans require a California-registered PE to re-certify any technical amendment. Administrative changes like updated phone numbers or contact names do not require re-certification.
• Monthly and annual inspections. Required by the SPCC rule and by the inspection procedures written into your plan. These are the ongoing record that the plan is being implemented. For what these inspections cover and how they differ from an inspection by your local CUPA (in California, which may be a county environmental health department, fire department, or another local agency depending on jurisdiction), see our SPCC inspection requirements guide.

An updated plan with no inspection program behind it is a paper exercise. An inspection program tied to an outdated plan is a documented record of a facility that no longer matches its own SPCC plan. Inspectors notice both.

What “A Plan on the Shelf” Actually Means

When we walk a facility for an SPCC update, the first thing we ask for is the prior plan and the inspection logs. The pattern we see most often is a plan from a previous consultant in a binder on a shelf, never opened since delivery, with no monthly inspection records and no signed five-year review. The facility paid for a plan and assumed compliance was finished. It wasn’t.

We have walked into facilities where the plan existed on the company’s CERS account but no one on site knew it was there, had a copy, or had heard the term “monthly visual inspection.” That’s not a regulatory edge case. It is, in our experience, the most common state of an outdated SPCC plan in California.

The fix is usually three things at once: a current review or amendment depending on what’s changed, setting up the monthly and annual inspection program using STI-format logs, and putting the renewal date on a tracked compliance calendar so the next review does not slip past five years.

California-Specific Considerations

In California, an SPCC update often runs alongside an APSA review. APSA is the Aboveground Petroleum Storage Act, administered by your local CUPA (which may be a county environmental health department, fire department, or another local agency depending on jurisdiction). APSA covers petroleum products specifically, while federal SPCC covers all oils, including vegetable, animal, synthetic, and mineral oils. The Title 19 update that took effect December 17, 2024 changed parts of the APSA program, including elements that may affect what’s reported on your Tank Facility Statement in CERS, the state’s online environmental reporting portal.

When we update an SPCC plan for a California facility, we check both layers. We make sure the federal SPCC plan reflects current facility conditions, and we confirm the CERS APSA submittal still matches the facility’s tank inventory. Mismatches between the two are a common finding during CUPA inspections.

What the Update Process Involves

Once an update is identified, the work follows the same path as a new plan, narrower in scope:

1. Review the existing plan, inspection logs, and prior site notes.
2. Walk the facility to verify current conditions and document changes since the last review.
3. Update the affected sections of the plan: Facility Information, Bulk Storage Containers, Secondary Containment, Transfer Operations, and any others touched by the change.
4. Recalculate containment capacity if anything in the containment system changed.
5. Update facility drawings to reflect current layout.
6. Document the change in the Record of Revision page.
7. Re-certify with a California-registered PE if the amendment is technical.
8. Confirm the inspection program is current and the next five-year review is on the compliance calendar.

Next Steps

If your plan is approaching five years, if your facility has changed since the last review, or if you have a plan but no inspection program behind it, an outside review is the fastest way to confirm where you actually stand. Whether a revision or a full rewrite makes more sense also drives price; see what affects the cost of an SPCC plan.
