What are the key considerations in designing a hazardous waste treatment, storage, and disposal facility (TSDF)?

TSDF design requires: site selection (away from habitation, flood zones, groundwater recharge areas), waste characterization and compatibility testing, segregated storage with secondary containment (110% capacity), treatment selection based on waste streams (physical-chemical for metals, incineration for organics, stabilization for disposal). Secured landfill design: double composite liner (HDPE + compacted clay), leachate collection/treatment, groundwater monitoring wells. Include emergency response, fire protection, and worker safety systems. Compliance with Hazardous Waste Rules and environmental clearances mandatory.
