Overview 

Healthcare facilities, including pharmacies, must manage hazardous waste pharmaceuticals in accordance with federal environmental regulations established under the Resource Conservation and Recovery Act (RCRA), enforced by the Environmental Protection Agency. 

 

The EPA’s Subpart P framework streamlines hazardous pharmaceutical waste management in healthcare settings and establishes clear rules for identification, segregation, storage, transport, and disposal of hazardous waste pharmaceuticals. 

 

Compliance requires alignment with federal rules as well as any applicable state and local environmental regulations, which may be more restrictive. 

 
Key Definitions 

Hazardous Waste 

Waste material (solid, liquid, or other forms) that poses a risk to human health or the environment due to characteristics such as toxicity, ignitability, corrosivity, or reactivity. 

 

Medical Waste (Regulated Medical Waste) 

Healthcare-generated waste contaminated with blood, bodily fluids, or other potentially infectious materials. 

 

Hazardous Waste Pharmaceutical (HWP) 

A pharmaceutical that is discarded and exhibits hazardous waste characteristics under RCRA. 

 

Non-Creditable Hazardous Waste Pharmaceutical 

Pharmaceutical waste that: 

• Is not eligible for manufacturer credit  
• Includes investigational drugs, free samples, spill cleanup materials, contaminated PPE, and residues in containers  

 

Potentially Creditable Hazardous Waste Pharmaceutical 

Pharmaceutical waste that may qualify for manufacturer credit, typically: 

• In original packaging  
• Undispensed  
• Unexpired or within allowable expiration window  

 

Reverse Distributor 

An authorized entity that receives potentially creditable pharmaceuticals to evaluate eligibility for manufacturer credit. 

 
Core Compliance Requirements 

Prohibition on Sewer Disposal 

Hazardous waste pharmaceuticals must never be disposed of via sink, drain, or sewer systems. 

 

Waste Identification 

All hazardous waste generated in the pharmacy must be identified and categorized as either: 

• Pharmaceutical hazardous waste  
• Non-pharmaceutical hazardous waste  

Proper classification is required before disposal or accumulation. 

 

Generator Category Determination 

Facilities must determine their hazardous waste generator status: 

• Very Small Quantity Generator (VSQG)  
• Small Quantity Generator (SQG)  
• Large Quantity Generator (LQG)  

State regulations may modify classification thresholds or requirements. 

Generator category determines regulatory obligations under RCRA and Subpart P. 

 

Vendor Disposal Requirements 

All hazardous and medical waste must be managed through a licensed hazardous waste disposal vendor in compliance with federal and state requirements. 

 
Waste Segregation at Point of Disposal 

 

Non-Creditable Hazardous Waste Pharmaceuticals 

Must be: 

• Placed in labeled “Hazardous Waste Pharmaceuticals” containers  
• Kept closed when not in use  
• Stored securely to prevent unauthorized access  
• Segregated from incompatible waste streams  

Containers must include accumulation start dates and be shipped to a permitted Treatment, Storage, and Disposal Facility (TSDF) using proper manifests. 

Key requirements: 

• Must NOT be sent to reverse distributors  
• Must be shipped under hazardous waste manifest systems  
• Must be tracked and retained for regulatory recordkeeping  

Special handling note: 

• Certain drugs (e.g., arsenic-containing compounds) require separate handling based on disposal restrictions.  

 

Creditable Hazardous Waste Pharmaceuticals 

Must be: 

• Stored in secure, clearly labeled containers indicating “Do Not Dispense”  
• Segregated for potential manufacturer credit evaluation  

Shipping requirements: 

• Sent to a reverse distributor  
• Shipped via approved common carrier  
• Requires tracking and delivery confirmation  
• Requires signature upon delivery  
• Records retained per regulatory requirements  

 

Packaging and Transportation 

All hazardous waste pharmaceuticals must be: 

• Packaged to prevent leakage, breakage, or exposure  
• Labeled according to hazardous material requirements  
• Transported in compliance with Department of Transportation (DOT) rules  
• Shipped according to Safety Data Sheet (SDS) transport instructions  

 

Recordkeeping Requirements 

Facilities must maintain: 

• Manifests for non-creditable waste shipments (minimum retention period applies)  
• Delivery confirmations for creditable waste shipments  
• Documentation of waste classification and generator category  
• Inspection and compliance records as required  

 

Empty Container Standards 

Certain containers are considered “empty” and exempt from hazardous waste rules when: 

• Stock bottles, vials, ampules, or unit-dose packaging are fully dispensed using standard practices  
• Syringes are fully depressed  
• IV bags are fully administered  

Residual waste in inhalers, creams, aerosols, or partially used products is generally considered hazardous waste unless otherwise exempted. 

 

Controlled Substance Exception 

Controlled substances are not regulated as hazardous waste when: 

• They are disposed of according to DEA-approved destruction requirements  

 

Regulatory Scope 

Compliance must consider: 

• Federal RCRA requirements  
• Subpart P healthcare-specific rules  
• State environmental agency requirements (which may be more stringent)  

Facilities must continuously evaluate regulatory updates to maintain compliance. 

 

Key Takeaways 

• Hazardous pharmaceutical waste must never be sewered or disposed of casually  
• Proper classification (creditable vs non-creditable) determines disposal pathway  
• Reverse distributors are only used for potentially creditable waste  
• Non-creditable waste must go directly to a permitted hazardous waste facility  
• Generator status (VSQG, SQG, LQG) drives compliance obligations  
• DOT packaging and transport rules apply to all shipments  
• Documentation and tracking are required for regulatory compliance  
• State regulations may be stricter than federal requirements
