Hazardous Waste Management in California
If your facility generates hazardous waste in California, you are on the hook for a stack of requirements that touch identification, storage, training, shipping, reporting, and source reduction.
If your facility generates hazardous waste in California, you are on the hook for a stack of requirements that touch identification, storage, training, shipping, reporting, and source reduction. Each one has its own form, its own threshold, and its own agency. Most of our work starts with a phone call from someone who knows part of what they need to do, suspects there is more, and wants the whole picture.
Some readers already know what they want. They generated 2,300 kilograms in a single month last year and need a biennial report filed before March 1. They got a violation letter from the CUPA (the local hazardous waste regulator, which may be a county environmental health department, fire department, or another local agency depending on jurisdiction). They just inherited compliance from someone who left. If that is you, our phone number is below, and the rest of this page tells you what working with us looks like. Other readers are not sure whether any of this applies to them. They have a 55-gallon drum in the corner, a manifest from a hauler they signed last month, and a vague sense that something might be regulated. This page walks through the full lifecycle of hazardous waste in California so you can place yourself in it.
Signs You Need a Closer Look
Most calls about hazardous waste come from one of these triggers. If you recognize any of them, this is the right page.
- A CUPA inspector flagged something. A walkthrough turned up missing labels, an overdue training record, or accumulation areas that do not match what is on file. You have a corrective-action letter and a clock.
- You crossed a generator threshold without meaning to. A waste hauler missed a pickup, two months of accumulation went out in a single month, and suddenly you generated more than 1,000 kilograms in one calendar month. The state and federal definitions now treat you as a Large Quantity Generator with extra reporting and training obligations.
- March 1 is approaching. The federal Biennial Hazardous Waste Report (EPA Form 8700-13A/B) is due March 1 of every even-numbered year, covering waste you generated in the odd-numbered year before. If you were a Large Quantity Generator (LQG) in that year, you owe a filing.
- You just took over compliance. A predecessor left. You opened a binder labeled SB 14, found a plan from 2019, and have no idea whether anything has been updated since.
- A waste hauler refused a pickup or returned a manifest. Container labeling, accumulation start dates, or a missing or expired EPA ID number can hold up a shipment.
- An employee asked a question that turned out to be a problem. “What do you do with the rinse water?” gets answered, and the answer turns out to be a regulated disposal route nobody documented.
The Hazardous Waste Lifecycle in California
California treats hazardous waste as a sequence of stages, each with its own enforcement contact and required documents. The federal Resource Conservation and Recovery Act (RCRA) sets the baseline. California’s Hazardous Waste Control Law (22 CCR Division 4.5) is broader: more wastes regulated, stricter container, training, and recordkeeping rules. Day-to-day enforcement is delegated to your local CUPA, with the Department of Toxic Substances Control (DTSC) handling state-level reporting, IDs, and source reduction.
Most facilities sit somewhere in the middle of this lifecycle without realizing the whole thing applies.
| Stage | What triggers it | Who enforces it | What’s required |
|---|---|---|---|
| Identification | Any generation of hazardous waste | DTSC (state ID), US EPA (federal ID) | A California/EPA ID number on Form 8700-12, reactivated if dormant |
| Generator status | Volume generated in a calendar month | DTSC, CUPA | Classification as Very Small, Small, or Large Quantity Generator; status drives accumulation limits and training |
| Storage and accumulation | Drums, totes, tanks on site | CUPA | Labeled, dated containers; satellite accumulation rules; 90/180/270-day limits depending on status |
| Training | Anyone who handles or signs for waste | Cal/OSHA, DTSC | Hazardous Waste Handler training within 6 months of hire, annual refresher |
| Shipping and manifesting | Waste leaving the site | DTSC, US DOT, CHP | Uniform Hazardous Waste Manifest, e-Manifest in RCRAInfo, DOT shipping papers, placarding |
| Biennial reporting | LQG status in an odd-numbered year | US EPA, DTSC | EPA Form 8700-13A/B by March 1 of the even year |
| Source reduction (SB 14) | More than 12,000 kg/yr hazardous waste or 12 kg/yr extremely hazardous | DTSC | Source Reduction Plan, Performance Report, Summary Progress Report; 4-year cycle |
| Fees and recordkeeping | All of the above | CDTFA (the California Department of Tax and Fee Administration), DTSC, CUPA | Generation and handling fees; manifests retained 3 years; training records retained per Title 22 |
A facility that handles each stage on its own often discovers a gap by accident: the EPA ID was issued under a prior owner’s name, the training records went out with the last EHS manager, the SB 14 plan never got updated for a new process line.
EPA ID Numbers: the Entry Point
Every California generator needs an identification number issued through DTSC. Some larger or specific generators get a federal EPA ID directly. The ID is what every regulator, hauler, and treatment facility uses to track your waste. The number does not expire, but it can go dormant if a facility stops generating, changes ownership, or relocates. Reactivating it can be slower than getting a new one, especially when ownership records are out of date.
Read who needs an EPA ID number and how to get one in California. If you are trying to confirm an ID for your own facility or a vendor’s, we also have a guide to looking up an EPA ID number in DTSC and US EPA databases. For facilities that need to reactivate a dormant EPA ID or get a temporary EPA ID number ahead of a one-time cleanup or short-term project, that is a separate process with its own form path.
Biennial Reporting: the March 1 Filing
The federal Biennial Hazardous Waste Report is filed through EPA’s RCRAInfo system. It covers waste streams, quantities, management methods, generator status, and manifests for the reporting year. Only RCRA-classified hazardous waste counts toward the LQG threshold, which trips many California facilities up. Waste oil, for example, is hazardous under California rules but not under federal RCRA. A machine shop generating large volumes of waste oil may not actually trigger a federal biennial report.
This is where we sometimes tell clients they do not need the service they called about. Read the California biennial hazardous waste report for the full process, deadlines, and what we need from you. If you are not sure whether your facility qualifies, do you have to file a biennial report and what makes you a Large Quantity Generator walks through the RCRA versus non-RCRA distinction and how a single high-volume month can change your status for an entire reporting year.
SB 14 Waste Minimization: the 4-Year Plan
California Senate Bill 14, the Hazardous Waste Source Reduction and Management Review Act, requires facilities generating more than 12,000 kilograms of hazardous waste per year (or more than 12 kilograms of extremely hazardous waste) to prepare a Source Reduction Plan, a Performance Report, and a Summary Progress Report on a 4-year cycle. The 2023 reporting year drives a 2023 plan cycle; the next cycle covers 2027. Documents are not submitted to DTSC. They are retained on site and produced during inspection.
The most common SB 14 mistake we see is counting waste at the wrong point in the process. The threshold is measured at the starting point of waste generation, not after treatment, recycling, or wastewater discharge. Facilities that treat their own waste, or that discharge treated hazardous wastewater to sewer, frequently undercount and assume they fall below the threshold when they do not.
Read SB 14 waste minimization plans in California for the full requirement, including the wastewater rule, the qualifying waste-stream threshold, and the 4-year cycle. If your facility may qualify as a small business under California Government Code §11342, there is an abbreviated path: SB 14 Full Plan versus the Small Business Checklist compares the two options, and explains how we handle review-only engagements for clients who prepared their own plan and need a qualified Environmental Professional to verify and certify.
Training: HWH, RTK, and the HAZWOPER Question
California requires every employee who handles, signs manifests for, or ships hazardous waste to complete Hazardous Waste Handler (HWH) training. For Large Quantity Generators, 22 CCR §66262.17(a)(7) requires a formal training program with initial training within 6 months of hire and an annual review. Small Quantity Generators must make sure employees are thoroughly familiar with proper waste handling and emergency procedures under 22 CCR §66262.16(b)(7)(C). Right-to-Know (RTK) training is a parallel requirement under Cal/OSHA for any employee exposed to hazardous materials, and the populations rarely match. A 320-employee site might have 30 actual waste handlers.
Two things to know up front. First, CDMS provides HWH training and DOT hazmat training. We do not provide HAZWOPER training. The two are commonly confused because both involve hazardous materials, but HAZWOPER applies to emergency responders and cleanup workers, not generators handling routine waste. Second, the training has to reflect your facility. A boilerplate online course covers RCRA in general; it cannot describe your accumulation area, your contingency plan, or the chemicals your team actually touches.
Hazardous waste handler and right-to-know training in California explains how we deliver the training and what gets covered. RCRA, HAZWOPER, or right-to-know: which training does your facility need is the comparison piece for facilities trying to sort out who needs what. For workforces that are more comfortable in Spanish, bilingual hazardous waste training for California facilities covers our English and Spanish delivery for both in-person and online formats.
Storage, Shipping, and the Manifest
A waste container becomes a regulatory document the moment a label goes on it. Container condition, labeling, accumulation start dates, and the area it sits in are all inspected against Title 22 rules. Satellite accumulation areas have their own limits separate from the main 90/180/270-day storage area. When waste leaves the site, the Uniform Hazardous Waste Manifest is the legal record. e-Manifest in RCRAInfo now applies to most shipments. DOT shipping papers, placarding, and the CA Carrier ID number add a layer of transportation compliance on top.
Hazardous waste storage, accumulation, and when you need tank certification covers the day-to-day storage rules and the point where a hazardous waste tank assessment becomes its own requirement. DOT hazmat shipping and hazardous waste manifesting in California walks through the manifest itself, e-Manifest in RCRAInfo, common manifest errors and how to correct them, and the CA Carrier ID and Motor Carrier Permit requirements that CHP enforces.
Keeping It Going Year-Round
The reason facilities call about a single document, an EPA ID or a biennial report, is usually that the rest of their program has gone untouched for a year or two. The hazardous waste lifecycle does not pause between filings. Manifests come in. New employees get hired. A new process line generates a new waste stream that needs a determination. Containers get stored in places they should not be.
Keeping up with hazardous waste compliance year-round covers what ongoing management looks like: who watches the deadlines, who reviews the manifests, who updates the SB 14 plan when production changes. It is the difference between scrambling in February and walking into March 1 with the report already drafted.
How CDMS Approaches Hazardous Waste Management
We are a California EHS firm. Since 1988, we have built and maintained hazardous waste programs for manufacturers, chemical distributors, food processors, warehouses, labs, and other regulated facilities across the state. Two things define how we work.
We come to your site.
Our consultants drive to your facility. They walk the accumulation areas, look at the containers, talk to the operators, review the manifests on file, and watch what actually happens. That is how we identify gaps a desk review or a software portal will not catch.
We handle the whole lifecycle.
EPA ID, training, storage, shipping, manifesting, biennial reporting, and SB 14 are not separate engagements with separate vendors. The same team that registers your ID drafts your SB 14 plan. The same consultant who walks your storage area builds the training appendix your operators see. That continuity is what keeps programs current when staff turn over.
What you get from a hazardous waste engagement with us depends on what you need. Some clients hire us for a single deliverable: a biennial report, a Small Business Checklist, a manifest correction letter. Many move into ongoing management after the first project, which folds the recurring obligations (training, biennial reporting, SB 14 updates, compliance calendar) into a regular schedule.
Frequently Asked Questions
What is the difference between RCRA hazardous waste and California hazardous waste?
RCRA is the federal program. California has its own list of regulated wastes on top of the federal list. Some materials, including waste oil and certain metal-bearing wastes, are hazardous in California but not under federal RCRA. That distinction matters because federal thresholds (like the LQG threshold for biennial reporting) only count RCRA waste, while California fees, manifesting, and SB 14 use the broader state list.
What is a Large Quantity Generator?
A facility that generates 1,000 kilograms or more of RCRA hazardous waste in any single calendar month, or that generates or accumulates more than 1 kilogram of acute hazardous waste, or more than 100 kilograms of spill cleanup material contaminated with acute hazardous waste. A single month over the LQG threshold can trigger the biennial report for that reporting year, though generator-category obligations are evaluated based on each calendar month.
Do we need an EPA ID number if we only generate small amounts?
California requires almost every hazardous waste generator to have an identification number, including Very Small Quantity Generators. The threshold for needing an ID is lower than the threshold for biennial reporting. Read more on who needs an EPA ID number in California.
How often does hazardous waste handler training need to happen?
For LQGs, initial training within 6 months of hire and an annual review, per 22 CCR §66262.17(a)(7). SQGs must make sure employees are thoroughly familiar with proper waste handling and emergency procedures under 22 CCR §66262.16(b)(7)(C). Training records must include dates, topics covered, and materials used, and must be available for inspection.
Can our most recent biennial report substitute for the SB 14 Performance Report?
For small businesses using the Compliance Checklist option under SB 14, the most recent Biennial Report may substitute for the Performance Report component. The Source Reduction Plan and the Summary Progress Report are still required.
We were visited by an inspector and got a violation letter. What now?
Call us before responding. A CUPA violation letter has a clock attached, and the response shapes whether the issue closes out cleanly or escalates. Many of our urgent-engagement calls start exactly here.
Trusted throughout California
BSY started working with CDMS last year after our in-house EHS person departed the company. CDMS reviewed our existing operational permits as well as any additional Federal, State and Local regulations that could apply and helped us to create a comprehensive compliance calendar to track regulatory deadlines and submittal due dates. The CDMS team does an excellent job of tracking everything and can be relied upon to complete the forms accurately and assist with submittals, allowing me to focus on our business.
