In the state of California, the Medical Waste Management Program (MWMP), in the Environmental Management Branch, regulates the generation, handling, storage, treatment, and disposal of medical waste by providing oversight for the implementation of the Medical Waste Management Act (MWMA) (California Health and Safety Code Sections 117600 – 118360). The MWMP permits and inspects all medical waste offsite treatment facilities and medical waste transfer stations. Aspects of medical waste management are also controlled by the Occupational Safety & Health Administration (federal and/or state) and Department of Transportation (federal and state).

Medical waste generators must register with either their Local Enforcement Agency (LEA) or the California Department of Public Health (CDPH), depending on their location. They are required to submit a written Medical Waste Management Plan to the appropriate authority. Containers used for medical waste must be labeled with either “Biohazardous Waste” or a biohazard symbol, and they must possess qualities such as being leak-resistant, having tight-fitting covers, and being maintained in a clean condition. Secondary containers must also be appropriately labeled. The Interim Storage Area must either be locked or supervised and must display the biohazard symbol. The Designated Accumulation Area should be secure, have bilingual warning signs, and adhere to state requirements. Storage times for generators producing 20 lbs. or more of biohazardous waste per month are restricted to 7 days (if stored above 32°F) and 90 days (if stored at or below 32°F). Moreover, emergency spill procedures and updated emergency contact lists are mandatory.
