SB 14 Waste Minimization Plans in California
If your facility generates more than 12,000 kilograms of hazardous waste in a year, California requires you to build a waste minimization plan under SB 14 (the Hazardous Waste Source Reduction and Management Review Act of 1989).
If your facility generates more than 12,000 kilograms of hazardous waste in a year, California requires you to build a waste minimization plan under SB 14 (the Hazardous Waste Source Reduction and Management Review Act of 1989). The plan is not filed with anyone. It is kept on site, on a four-year cycle, and an inspector can ask to see it the next time they walk through your door.
That last part is where most facilities get caught. The documents are not submitted to DTSC (the California Department of Toxic Substances Control), so it is easy to forget about them. DTSC has not forgotten. They compare manifest data to filing records and send non-filer letters with a roughly 30-day window to comply. Failure to prepare or make required SB 14 documents available can expose the facility to continuing penalties and enforcement follow-up.
For a wider view of how this fits with EPA ID registration, manifesting, and biennial reporting, see our California hazardous waste management guide.
Who Has to Prepare an SB 14 Plan
The thresholds are absolute, measured per facility, per calendar year:
| Trigger | Threshold |
|---|---|
| Hazardous waste generated | More than 12,000 kg/year (about 26,400 lbs or 13.2 tons) |
| Extremely hazardous waste generated | More than 12 kg/year (about 26.4 lbs) |
| Aqueous hazardous waste treated on site | More than 3,100 gallons/year |
One detail trips up nearly every first-time filer: hazardous wastewater counts. Even if you treat it on site and discharge it as non-hazardous, the volume counts toward your SB 14 threshold. The rule is based on the waste at its starting point, before any recycling, treatment, or volume reduction. Facilities that look at their manifest totals alone routinely undercount. When we walk a metal-finishing or plating site, the first thing we ask about is the rinse and treatment system, because the wastewater is almost always the largest hazardous waste stream and the one the in-house team forgot to include.
If you are not sure whether you cross the threshold, this is the same question as your biennial report obligation. The waste-volume math is the same; the deadlines and deliverables differ.
The Four-Year Cycle and What You Owe
SB 14 plan due years occur every four years: 1991, 1995, 1999, 2003, 2007, 2011, 2015, 2019, 2023, 2027. Each plan is based on the prior year’s hazardous waste generation data and is due by September 1 of the plan year. The plan due September 1, 2027 is based on 2026 generation data. The plan is retained on site and must be available during inspection.
A full SB 14 package contains three documents:
Source Reduction Evaluation Review and Plan (SRERP).
Process block diagrams, waste stream identification, and evaluation of source reduction measures across five DTSC-recognized approaches: input changes, operational improvements, production process changes, product reformulation, and administrative steps. The SRERP also includes an implementation timetable and a numerical reduction goal.
Hazardous Waste Management Performance Report.
A look at where the waste is generated and how it is handled.
Summary Progress Report (SPR).
Reports on progress against the previous cycle’s goal.
All three must be certified by a qualified Environmental Professional. Small businesses (independently owned, fewer than 250 manufacturing employees or under $2 million in services gross receipts) can use a Compliance Checklist in place of the full SRERP, and the most recent biennial report can substitute for the Performance Report. For more on which version fits your facility, see our breakdown of the Full Plan, Small Business Checklist, and review-only engagement options.
How DTSC Enforces It
The plan is retained on site, not submitted. That changed around 2015. What did not change is enforcement. DTSC pulls generator data from manifests and biennial reports, identifies facilities over the threshold, and cross-references against SB 14 submissions on file from prior cycles. If your facility shows hazardous waste volume that triggers SB 14 and you do not have a current plan, you can expect a letter.
A few patterns we see repeatedly during inspections and after enforcement letters:
- The plan was prepared once, years ago, and never updated. The cycle moved past 2019 or 2023 and nobody at the facility was tracking it.
- The plan exists but cannot be located on site during inspection. SB 14 documents must be available during inspection. “It’s on a former employee’s laptop” is not available.
- Wastewater was excluded from the threshold calculation, so the facility convinced itself SB 14 did not apply. DTSC’s view of your generator volume includes the wastewater you treated and discharged.
- The implementation schedule from the prior plan was missed. A generator can amend the implementation schedule without penalty, but missing the schedule and ignoring it can draw continuing penalties.
The “NO” determination letter is also a legitimate option. If you are genuinely below the thresholds, that finding should be documented and retained the same way the plan would be. Inspectors accept a documented not-applicable determination; they do not accept silence.
What the Plan Actually Looks Like When We Prepare One
The deliverable is a binder (and an editable file set) organized around your facility’s waste streams. We start with a request for your manifests, RCRA data, prior SB 14 reports if any exist, and any process documentation you already have. The on-site portion is structured as an interview and a brainstorming session: we walk the operation, verify the process flow diagrams against what is actually happening on the floor, and work through source reduction ideas with the people who run the processes. Most often we find at least one waste stream documented incorrectly, either because a process changed and the paperwork did not catch up, or because a smaller side stream was rolled into a larger one.
The formal evaluation applies DTSC’s seven evaluation criteria to each source reduction measure identified during brainstorming. Major waste streams (more than 5% of total hazardous waste, or more than 5% of total volume for wastewater) get the full evaluation. Streams below the 5% line are documented but excluded from detailed evaluation. The numerical reduction goal and implementation timetable come out of that analysis, and the Environmental Professional certifies the technical and financial portions.
“I Already Prepared It, I Just Need Someone to Sign”
This is the most common call we get on SB 14. A facility manager or compliance lead has built the plan internally, run the calculations, and drafted the certifications. They want a third party to review the work and sign it.
Two things make this harder than it looks. First, the certification is a technical and financial statement, not a signature on a finished document. The Environmental Professional has to understand and validate the work, which means verifying the calculations and seeing the processes described in the plan. Second, self-prepared plans frequently miss the wastewater volume, undercount waste streams that pre-treatment removed, or skip evaluation criteria that DTSC expects to see in the SRERP.
The way we handle this is a staged review. The first stage is a site visit, a desk review of what you have, and a written list of deficiencies. The second stage is the corrections and the certification. If your plan is in good shape, the second stage is short. If it needs more work, you can decide whether to take the deficiency list and do the corrections yourself or have us complete them. Either way, you are not paying for a full rewrite of a plan that is already 80% done.
We always ask for editable files, never PDFs. Working from a PDF doubles the work for everyone.
What Happens If You Missed a Cycle
Catch-up filings are normal. The 2019 cycle is over; if your facility was over threshold in 2018 and never produced a plan, that plan still needs to exist. The same is true of the 2023 cycle if your 2022 generation data triggered it. DTSC’s enforcement priority is whether you have a current, defensible plan available now, not punishing every historical gap. Getting current before a non-filer letter arrives is meaningfully better than responding to one.
The CUPA (your local hazardous waste regulator, which may be a county environmental health department, fire department, or another local agency depending on jurisdiction) will also ask about SB 14 during a hazardous waste generator inspection. If you are facing a CUPA finding tied to waste minimization, the response is the same: build the plan, certify it, retain it on site, and document the corrective action.
What to Have Ready When You Call
To scope an SB 14 engagement quickly, it helps to have:
- Your annual hazardous waste generation total (tons or kilograms)
- Whether you generate any extremely hazardous waste
- Whether you have hazardous wastewater, and your treatment volume if you treat on site
- The date of your last SB 14 plan, if any, and who prepared it
- Approximate count of waste streams and major processes
- Any letter you have received from DTSC or your CUPA
