Introduction:

• The Resource Conservation and Recovery Act (RCRA), enacted in 1976, is the principal federal law in the United States governing the disposal of solid and hazardous waste.
  
• RCRA separates waste into "Listed Wastes" (F, K, P, and U lists) and "Characteristic Wastes" (Ignitability, Corrosivity, Reactivity, and Toxicity).
  
• However, for economic or practical reasons, certain large-volume wastes or wastes regulated under other acts are specifically excluded from being classified as hazardous waste under Subtitle C, even if they exhibit hazardous characteristics.
  

Information Booster:

• The Resource Conservation and Recovery Act (RCRA) in the United States provides a framework for proper management of hazardous and non-hazardous waste.
  
• According to the RCRA guidelines:
  
• Fly ash : Not classified as hazardous waste under RCRA; it is regulated as solid waste unless proven otherwise.
  
• Fly ash, while not hazardous, must be managed carefully to prevent environmental harm.
  
• Arsenic-treated wood : Generally not classified as hazardous under RCRA, but specific treated wood waste could be managed differently in certain states or under particular circumstances.
  
• Used mainly in outdoor structures, it is not typically regulated as hazardous waste unless subjected to specific conditions. However, improper disposal could release arsenic, posing health risks.
  
• Used chlorofluorocarbon refrigerants : Not classified directly under hazardous waste in RCRA but regulated under the Clean Air Act for proper disposal due to their impact on ozone depletion.
  
• These refrigerants are regulated under the Clean Air Act due to their environmental impact, specifically ozone layer depletion. RCRA does not explicitly list them as hazardous.
  

Additional knowledge:

• Commercial chemical product DDT : Considered a hazardous waste due to its persistence and toxicity in the environment.
  
• E-waste : Although not specifically regulated under RCRA, it can contain hazardous substances like lead and mercury, which make it potentially hazardous.
