Pharmaceutical Waste Disposal Guidelines in California

California pharma waste rules for facilities & patients: DEA, EPA, CDPH, DTSC compliance + PureWay disposal & training solutions.

Updated over 3 months ago

(DEA, EPA) as well as state-specific rules governed by the California Department of Public Health (CDPH) and the California Department of Toxic Substances Control (DTSC).

The requirements differ depending on whether the generator is a healthcare facility or an individual (patient) at home.


🔹 Healthcare Facilities in California

Healthcare facilities in California—such as hospitals, clinics, pharmacies, long-term care, and veterinary clinics—must comply with multiple overlapping requirements for pharmaceutical waste disposal. Here's a breakdown:

1. Hazardous Waste Pharmaceuticals (RCRA and California-RCRA)

  • Federal RCRA hazardous waste pharmaceuticals must be managed under the EPA Subpart P (40 CFR 266).

  • California-designated hazardous wastes (called “non-RCRA hazardous waste”) are also regulated under Title 22 of the California Code of Regulations.

  • California uses a broader list of hazardous pharmaceuticals compared to federal standards.

🛠️ Action: Use a waste profile to determine if a pharmaceutical is federally hazardous, California-only hazardous, or non-hazardous.

2. Subpart P – EPA Regulations for Healthcare Facilities

  • Must comply with Subpart P for managing hazardous waste pharmaceuticals (if a Large Quantity Generator or Reverse Distributor).

  • Sewering (flushing) of hazardous waste pharmaceuticals is prohibited under both federal and state rules.

  • Maintain a pharmaceutical waste management plan and employee training.

3. Non-Hazardous Pharmaceutical Waste

  • Includes over-the-counter (OTC), non-RCRA hazardous, and expired non-controlled meds.

  • Must be managed as medical waste per California’s Medical Waste Management Act.

  • Disposal through medical waste haulers or approved mail-back programs.

4. Controlled Substances (DEA Schedule II–V)

  • Must be destroyed per DEA requirements (21 CFR 1317).

  • Destruction must render substances non-retrievable.

  • Destruction must be witnessed and documented.

🛠️ Action: Partner with a DEA-registered reverse distributor or use on-site destruction technology that meets DEA’s non-retrievable standard.

5. Labeling, Storage, and Transportation

  • Clearly label containers as "Pharmaceutical Waste – Incineration Only" (for hazardous/non-hazardous Rx).

  • Store separately from regulated medical waste and sharps.

  • Use licensed hazardous or medical waste transporters.

🔹 Patients (At-Home Pharmaceutical Waste Disposal)

Patients at home face a different set of rules. While they are not considered "generators" under hazardous waste laws, they must still follow safe disposal practices:

1. Prescription Medications (Non-Controlled)

  • Preferred: Use authorized drug take-back programs or DEA-registered collection receptacles.

  • Alternative: Use a pharmaceutical mail-back envelope (offered by some pharmacies or PureWay partners).

  • Last resort: Dispose in household trash only after:

    • Mixing meds with an unpalatable substance (e.g., used coffee grounds)

    • Sealing in a plastic bag

    • Marking “DO NOT RECYCLE”

2. Controlled Substances (Schedule II–V)

  • Must go to a DEA-authorized collection site (e.g., pharmacy or police station).

  • Cannot be mailed back unless using a DEA-compliant mail-back envelope.

3. Sharps with Residual Pharmaceuticals (e.g., insulin pens)

  • Must be disposed of in approved sharps containers.

  • Sharps must not go into household trash in California.

  • Disposal options:

    • Mail-back sharps containers (PureWay offers CA-compliant kits)

    • Local drop-off sites (check city/county programs)

⚠️ Penalties for Noncompliance

Pharmaceutical waste disposal procedure violations can result in:

  • Fines from DTSC or CDPH

  • DEA enforcement actions for improper controlled substance disposal

  • OSHA citations for unsafe workplace practices (in healthcare settings)
