RCRA Subpart P Explained: Hazardous Pharmaceutical Waste Rules
If your facility disposes of medications, RCRA Subpart P is the EPA rule you can’t ignore. It governs how hazardous pharmaceutical waste must be handled — and it bans a practice a lot of facilities still do. Here’s what it requires, in plain English.
What is RCRA Subpart P?
Subpart P (40 CFR Part 266) is the EPA’s Management Standards for Hazardous Waste Pharmaceuticals. It sets how healthcare facilities and reverse distributors must handle RCRA-hazardous pharmaceutical waste — and, critically, it prohibits sewering (flushing) hazardous pharmaceuticals down the drain.
Which pharmaceuticals are RCRA-hazardous?
Three categories:
- P-listed — acutely hazardous (warfarin above certain levels, nicotine, epinephrine, physostigmine)
- U-listed — toxic pharmaceuticals and residues
- Characteristic (D-codes) — ignitable, corrosive, or toxic drugs
Common surprises: nicotine (P075) and warfarin are P-listed acutely hazardous waste, not regular trash.
What Subpart P requires of facilities
- Identify and segregate hazardous pharmaceutical waste
- Use labeled, closed, leak-proof containers
- Never sewer (flush) hazardous pharmaceuticals
- Manifest and ship to a permitted destruction facility
- Keep documentation and Certificates of Destruction
We handle the identification and RCRA-hazardous pharmaceutical waste so hazardous drugs never end up in the red bag or the drain.
