Despite making promises, the Capital Development Authority has failed to shift steel re-rolling mills out of the city limits to protect the residents against pollution.

On the other hand, the owners of the steel mills in I-9 and I-10 sectors are of the view that they cannot shift their units due to the high cost.

An official said former chairmen, including Kamran Lashari, Tariq Mehmood and Imtiaz Inayat Elahi, had announced their decisions to set up an industrial zone in Sector I-17 and H-16, so that all industrial units could be shifted there.
