Port Blair, May 28: The Port Blair Municipal Council has cautioned the general public against dumping unauthorised construction materials, debris etc. which has become a nuisance in the city. In a Press Note issued today, the Secretary PBMC issued an advisory not to dump such materials at the brim/ embankment of the roads. The general public has also been suggested to pass on information on such illegal dumping on PBMC’s Helpline No. 231179 & 245789 for lifting of such materials from the construction site itself. Throwing of debris/malba/garbage on roadside will attract punitive action, said the Secretary.
