California Medical Waste Compliance Guide
California regulates medical waste under the Medical Waste Management Act (MWMA). Generator storage time limits depend on monthly quantity and temperature, and generators must register with their local enforcement agency (LEA) (or CDPH where applicable).

| Authorized Haulers | Medical waste generally hauled by a registered hazardous waste hauler (or allowed alternatives such as mail-back where applicable) per MWMA. |
| Employee Training | Training is required for onsite treatment operators and should align with OSHA bloodborne pathogens requirements; maintain training documentation per MWMA provisions for onsite treatment. |
