The document outlines guidelines for the design, establishment, operation, and closure of common hazardous waste treatment, storage, and disposal facilities in India. It discusses several key aspects of setting up such facilities including site selection criteria, planning and design considerations, environmental monitoring requirements, landfill liner and cover specifications, leachate and landfill gas management systems, and closure and post-closure plans. The guidelines aim to ensure that hazardous waste facilities are established and operated in a safe and environmentally sound manner.

1. Design of Common Hazardous Waste Treatment, Storage and
Disposal Facilities
By
N.K. Verma
Former Additional Director
CPCB
Hazardous Waste ( M & H ) Rules, 1989

the occupier or any operator of facility, or any association of occupiers to
acquire the site(s) for setting up the facility for treatment, storage and disposal
of hazardous wastes. The state Govt. shall also compile and publish
periodically an inventory of such HW disposal sites or facility.

Closure Post Closure Period : 30 years
c) Waste Volume, Waste Compatibility and Landfill Capacity:
o Volume of Waste: Volume of waste to be placed in a landfill will be
computed
o Compatible waste only be disposed
o Actual volume of landfill to be computed taking into account the
volume occupied by liner system and the cover material as well as
compacted density of the waste.
o Total landfill area: based on
o Designed height of landfill : 5 to 20 m
o 15 to 20 % area more than the required area towards infrastructure facility

prescribe as per the local needs and conditions; these will be more stringent than
those prescribed above. However, in case of clusters of units, the State Pollution
Control Board may prescribe suitable limits.
