The Supreme Court on Friday directed the Delhi government to close down all industrial units set up in residential and non-conforming areas after August 1, 1999.
The court said, light household industries would, however, be allowed to continue in these areas.
The court said all heavy industries and hazardous chemical units will have to be closed forthwith if they are found to be operating in the residential and non-conforming areas.
The court gave four months time for the closure of 'F' category industries and five months for the light service industries.
The court directed the central government to determine within three months as to which are the permissible household industries, which would be allowed to operate in the residential areas.
The apex court also directed the Delhi government to announce within six weeks a policy for rehabilitation of those industries, which have been marked for closure.
The court said all those industries, which have been directed to close down if found violating the deadline would face disconnection of water and electricity supply.
