Understanding California IBC Compliance
California has some of the most stringent environmental and safety regulations in the nation. Businesses that store, handle, transport, or dispose of IBC tanks must comply with a layered system of federal, state, and local requirements. This guide breaks down the key regulations and agencies you need to know about.
Important Disclaimer
This guide is provided for informational and educational purposes only. It is not legal advice. Regulations change frequently and may vary by jurisdiction. Always consult with a qualified environmental compliance professional or attorney for guidance specific to your situation. Contact your local CUPA for the most current requirements in your area.
Key California Regulatory Agencies
Multiple state agencies oversee different aspects of IBC tank operations. Understanding which agencies apply to your operations is the first step toward compliance.
Department of Toxic Substances Control (DTSC)
Regulates hazardous waste generation, transportation, treatment, storage, and disposal
If your IBC tanks hold or previously held hazardous materials, DTSC regulations apply to storage, labeling, and disposal of both the contents and the containers.
Key Regulations
- Title 22, Division 4.5, California Code of Regulations
- Hazardous waste container management standards (equivalent to federal RCRA)
- 90-day accumulation rules for hazardous waste generators
- Container condition and compatibility requirements
- Manifest requirements for hazardous waste transport in IBCs
- Closure and post-closure requirements for storage facilities
California Department of Resources Recycling and Recovery (CalRecycle)
Oversees recycling, waste reduction, and resource recovery programs statewide
CalRecycle sets recycling standards and diversion goals that affect how IBC tanks are recycled and disposed of. Businesses must divert specific percentages of waste from landfills.
Key Regulations
- AB 341: Mandatory commercial recycling for businesses generating 4+ cubic yards of waste per week
- SB 1383: Organic waste reduction requirements (affects food-grade IBC management)
- Rigid plastic packaging container (RPPC) requirements
- Extended producer responsibility (EPR) programs
- Waste diversion goals and reporting requirements
- Recycling market development zone incentives
State Water Resources Control Board (SWRCB)
Protects water quality across all California surface and groundwater
IBC storage areas must prevent leaks and spills from reaching waterways, storm drains, and groundwater. Stormwater permits may require specific containment measures for outdoor IBC storage.
Key Regulations
- Industrial General Permit (IGP) for stormwater discharges
- Spill Prevention, Control, and Countermeasure (SPCC) requirements
- Best Management Practices (BMPs) for container storage areas
- Groundwater monitoring requirements for facilities with large container storage
- Reporting requirements for spills or unauthorized discharges
- Underground storage tank (UST) regulations (if applicable to IBC setups)
California Air Resources Board (CARB)
Regulates air quality and emissions across the state
IBCs storing volatile organic compounds (VOCs) or hazardous air pollutants must comply with emissions controls. Proper sealing, venting, and vapor recovery may be required.
Key Regulations
- Air Toxics Hot Spots Information and Assessment Act (AB 2588)
- Rule 463 (SCAQMD): Organic liquid storage requirements
- VOC emission limits for container storage and transfer operations
- Vapor recovery requirements during filling and dispensing
- Facility emissions inventory reporting
- New source review permits for facilities above threshold quantities
Local and Regional Requirements
Beyond state regulations, local fire departments, CUPAs, building departments, and air quality districts impose additional requirements for IBC tank operations.
Fire Code Compliance
California Fire Code (based on International Fire Code with state amendments) governs the storage of flammable and hazardous materials in IBC tanks.
- Maximum Allowable Quantities (MAQ) per control area for each hazard class
- Separation distances between IBC storage and buildings, property lines, and ignition sources
- Fire suppression system requirements in IBC storage areas
- Secondary containment for flammable liquid IBCs
- Operational permits from local fire department for above-threshold quantities
- Hazardous materials management plan (HMMP) filed with local CUPA
Certified Unified Program Agency (CUPA)
Every California county has a CUPA that serves as the local enforcement agency for hazardous materials and waste programs.
- Hazardous Materials Business Plan (HMBP) filed electronically via CERS
- Annual permit fees for hazardous material storage facilities
- Routine inspections by CUPA inspectors (typically every 1-3 years)
- Emergency response and contingency planning documentation
- Employee training records for hazardous material handling
- Reporting of any release or threatened release of hazardous materials
Building and Zoning
Local building codes and zoning ordinances may restrict IBC storage locations and require permits for new storage areas.
- Zoning compliance: verify IBC storage is permitted in your zone classification
- Building permits for constructing covered IBC storage structures
- Setback requirements from property lines, streets, and adjacent buildings
- Floor load capacity verification for indoor IBC storage areas
- ADA accessibility requirements for IBC storage in accessible work areas
- Stormwater management requirements for outdoor IBC storage pads
South Coast Air Quality Management District (SCAQMD)
Businesses in the South Coast Air Basin (including Orange County, where Santa Ana is located) must comply with SCAQMD rules for air emissions.
- Rule 463: Storage of organic liquids - requirements for IBC containers storing VOCs
- Rule 462: Organic liquid loading - vapor recovery during IBC filling operations
- Permit to operate for IBC storage above certain quantities of VOC-containing liquids
- Annual emissions reporting for facilities with air quality permits
- Compliance inspections by SCAQMD field staff
- Best Available Control Technology (BACT) requirements for new or modified IBC storage

Best Practices for California Compliance
Conduct Regular Self-Audits
Perform internal compliance audits at least quarterly. Use this guide as a starting point and supplement with agency-specific checklists from your CUPA.
Maintain Organized Records
Keep all permits, training records, inspection logs, manifests, and SDS files organized and accessible. Inspectors will ask for documentation during site visits.
Train All Employees
Ensure every worker who handles IBC tanks is trained on applicable regulations, hazard identification, PPE requirements, and emergency procedures.
Work with Licensed Vendors
Use licensed and permitted haulers, recyclers, and disposal facilities for all IBC waste streams. Verify their licenses before hiring.
Stay Current on Changes
California regulations update frequently. Subscribe to agency newsletters, join industry associations, and consult with compliance professionals to stay informed.
Document Everything
If it is not documented, it did not happen. Write down inspections, training, cleaning, spill responses, and any communication with regulators.
