Contaminated Materials Regulations
EPA RCRA Regulations
Mixture Rule:
Hazardous waste mixed with non-hazardous waste remains hazardous
Absorbents contaminated with hazardous materials become hazardous waste
Cannot "dilute" or "absorb" way from hazardous classification
Hazardous Waste Determination:
Materials contaminated with:
Listed hazardous wastes (F, K, P, U-lists) → Hazardous
Characteristic wastes (ignitable, corrosive, reactive, toxic) → Hazardous if exhibit characteristic
Non-hazardous materials → May still require proper disposal
Generator Requirements:
Determine hazardous waste status
Obtain EPA ID if SQG or LQG
Proper accumulation and labeling
Follow time limits
Use approved disposal facilities
Derived-From Rule
Critical concept:
Materials derived from treatment of listed hazardous waste remain hazardous
Contaminated materials from cleaning listed waste containers are hazardous
Residues and spill cleanup from listed wastes are hazardous
Used Oil Regulations
Oil-contaminated materials:
May be subject to used oil management standards
Depends on halogen content
Some materials qualify for used oil fuel blending
Less stringent than hazardous waste in some cases
Universal Waste
Some contaminated filters:
Paint booth filters may qualify in some states
Check state-specific regulations

Frequently Asked Questions
Q: Can I throw oil-soaked absorbents in the trash? A: No. Oil-soaked materials are typically hazardous waste (D001 ignitable) and are fire hazards. They require proper disposal.
Q: What if I wring out the oil - then can I trash the absorbent? A: No. Even wrung-out materials retain enough contaminant to be hazardous waste and remain flammable.
Q: Are absorbents used for water-based spills hazardous? A: Only if the water contained hazardous materials. Clean water spill absorbents are not hazardous.
Q: Can contaminated PPE be laundered and reused? A: Some PPE can be decontaminated and reused if properly designed for that purpose. Most disposable PPE should be disposed of as contaminated waste.
Q: How should I store oil-soaked shop towels? A: In fire-safe metal containers with self-closing lids, kept in well-ventilated areas away from heat sources. Never in open bins or plastic bags.
Q: What causes spontaneous combustion in oil-soaked materials? A: Oils oxidize and generate heat. When materials are piled together, heat builds up until reaching ignition temperature.
Q: Can I use oil dry from my shop floor in my garden? A: No. Once contaminated with oil or other materials, oil dry is hazardous waste and cannot be used for other purposes.
Q: What about dust from sweeping the shop floor? A: If contaminated with oils, chemicals, or metal dusts, it should be treated as contaminated material requiring proper disposal.
Q: How do I dispose of paint booth filters? A: As contaminated materials with proper characterization. They're typically hazardous waste due to paint and solvent content.
Q: Can contaminated soil be cleaned and reused? A: Sometimes, through soil washing or treatment. We can discuss options based on contamination type and levels.
Q: What if I have an old spill that was never properly cleaned up? A: We can provide soil testing, removal of contaminated materials, and proper disposal with documentation.
Q: Do absorbent pads have to be fully saturated before disposal? A: No, but don't waste absorbent capacity. Use appropriate amounts and consolidate when safe to do so.
