A Guide to California Medical Waste Disposal Regulations

California is one of the states with some of the most stringent medical waste laws in the U.S. For healthcare facilities, clinics, laboratories, and waste haulers operating in California, complying with state medical waste regulations isn’t optional—it’s a legal necessity. Violations can lead to fines, reputational damage, and risks to public health.

What is “Medical Waste” Under California Law?

In California, the Medical Waste Management Act (MWMA) defines medical waste broadly. It includes:

• Biohazardous waste: items contaminated with blood, bodily fluids, or disease-causing organisms

• Sharps: needles, syringes, scalpels, lancets—anything that can puncture or cut

• Pathology waste: tissues, organs, body parts

• Trace chemotherapy waste: materials containing residues of cancer drugs

• Pharmaceutical waste: unused or expired medications (that aren’t regulated under hazardous waste laws)

Importantly, this definition applies to waste not regulated under federal hazardous waste rules (RCRA) but still posing a biological or infectious risk.

Regulatory Structure & Oversight

California Department of Public Health & Medical Waste Management Program

The California Department of Public Health (CDPH) runs the Medical Waste Management Program. This body oversees generator registration, permits for offsite treatment facilities and transfer stations, and enforcement of the MWMA. The program inspects sites, issues permits, and enforces standards. You can learn more from the CDPH’s official page for medical waste: Medical Waste Management Program (CDPH).

Local Enforcement Agencies & Local Jurisdictions

In some counties, the local environmental health or public health departments act as Local Enforcement Agencies (LEAs). Generators must register and file plans with their LEA if the state has delegated enforcement in that county.

Certification & Permits

Facilities that treat waste onsite or act as consolidation or transfer stations need permits under California’s regulations (in Title 22, Chapter 21, CCR) to operate legally.

Generator Obligations

Healthcare facilities and other waste generators bear the bulk of responsibility under the state law. Key obligations include:

Registration & Management Plans

• All generators must register with their local enforcement agency (or via CDPH if the state acts as LEA).

• Large Quantity Generators (LQGs)—those generating more than 200 pounds of medical waste per month—must submit a Medical Waste Management Plan (MWMP). This plan should outline how the facility handles segregation, storage, transport, treatment, and disposal processes.

Segregation at the Source

• Medical waste must be separated from regular trash at its point of generation.

• Sharps must go immediately into rigid, puncture-resistant containers.

• Other infectious or biohazardous wastes go into red biohazard bags or clearly labeled, leak resistant containers.

Storage & Containment

• Storage areas must be secured—locked or under supervision, protected from unauthorized access.

• Containers must be clearly labeled with “Biohazardous Waste” or “Biohazard” and display the universal biohazard symbol.

• In patient rooms, small amounts may go into biohazard bags (no more than 3 lbs or 1 gallon) before transfer to secondary containers. For storage beyond immediate use, waste must be held in rigid, labeled, leak-proof containers.

• The accumulated waste must not be held indefinitely; California imposes time limits on how long waste can be stored before treatment or removal.

Time Limits on Storage

• For large or significant generators: waste kept above 32°F typically must be transported or treated within 7 days.

• If stored below 32°F (refrigerated), the limit extends—often 90 days is permitted.

• For very small generators, limits may differ—but these time boundaries help prevent microbial growth or odor issues.

Transport & Hauler Regulations

Transport of medical waste in California is tightly regulated:

• Only licensed transporters may carry medical waste offsite.

• Vehicles must have proper labeling and display the biohazard symbol.

• Consolidation or transfer stations used during transit must also be permitted.

• Transporters must comply with recordkeeping, manifests, chain of custody, and safety rules under both state and federal (DOT) requirements.

Treatment & Disposal Requirements

Medical waste cannot simply be landfilled without treatment. California law mandates that waste be treated to render it noninfectious before final disposal. Permitted treatment methods include:

• Incineration

• Steam sterilization (autoclaving)

• Approved alternative technologies (as authorized by regulation)

After treatment, waste may be disposed of like regular solid waste, provided it no longer poses health risks.

For sharps waste, once sterilized and noninfectious, it can be disposed of as solid waste if public access cannot reach it, or using approved encapsulation or mail-back systems.

Recordkeeping, Inspections & Enforcement

To stay compliant, generators and transporters must maintain meticulous records:

• Copies of manifests, revenue bills, transport logs

• Records of treatment receipts, methods used, and disposal

• Documentation of staff training, plan updates, and management audits

• Records generally must be kept for at least two to three years, depending on generator type

Inspections by CDPH or local enforcement may occur regularly. Inspection may also cover physical facilities, storage areas, spill procedures, labels, staff training, and matching manifests to invoices.

Violations can yield fines, permit suspensions, or legal action. The law also authorizes injunctions or criminal penalties for serious breaches.

Practical Compliance Tips for Facilities & Haulers

1. Keep your plan current: Review and update your Medical Waste Management Plan regularly, especially as operations or staff change.

2. Train continuously: All staff who handle medical waste must receive training on state and federal rules, spill response, waste segregation, and PPE usage.

3. Monitor temperatures & storage times: Use refrigerators or coolers for storage when necessary, and track the duration of waste storage in your facility.

4. Automate manifest and record tracking: Digital record systems reduce the risk of lost papers, mismatches, or missing documents during audits.

5. Work with permitted haulers & facilities: Ensure that the transporters and treatment centers you use are permitted, compliant, and properly documented.

6. Plan for spill emergencies: Maintain a written emergency action plan as required by law and ensure that staff are aware of how to respond to leaks or accidents.

7. Review county and local rules: Cities or counties may impose stricter rules beyond those allowed by state law. Always check your local health department or environmental division.
