(1)  Subject to the provisions of this Act, the functions of a State Board shall be--

   (a)  to plan a comprehensive programme for the prevention, control or abatement of pollution of streams and wells in the State and to secure the execution thereof;

   (b)  to advise the State Government on any matter concerning the prevention, control or abatement of water pollution;

   (c)  to collect and disseminate information relating to water pollution and the prevention, control or abatement thereof;

   (d)  to encourage, conduct and participate investigations and research relating to problems of water pollution and prevention, control or abatement of water pollution;

   (e)  to collaborate with the Central Board in organising the training of persons engaged or to be engaged in programmes relating, to prevention, control or abatement of water pollution and to organise mass education programmes relating thereto;

   (f)  to inspect sewage or trade effluents, works and plants for the treatment of sewage and trade effluents and to review plans, specifications or other data relating to plants set up for the treatment of water, works for the purification thereof and the system for the disposal of sewage or trade effluents or in connection with the grant of any consent as required by this Act;

   (g)  to lay down, modify or annul effluent standards for the sewage and trade effluents and for the quality of receiving waters (not being water in an inter-State stream) resulting from the discharge of effluents and to classify waters of the State;

   (h)  to evolve economical and reliable methods of treatment of sewage and trade effluents, having regard to the peculiar conditions of soils, climate and water resources of different regions and more especially the prevailing flow characteristics of water in streams and wells which render it impossible to attain even the minimum degree of dilution;

   (i)  to evolve methods of utilisation of sewage and suitable trade effluents in agriculture;

   (j)  to evolve efficient methods of disposal of sewage and trade effluents on land, as are necessary on account of the predominant conditions of scant stream flows that do not provide for major part of the year the minimum degree of dilution;

   (k)  to lay down standards of treatment of sewage and trade effluents to be discharged into any particular stream taking into account the minimum fair weather dilution available in that stream and the tolerance limits of pollution permissible in the water of the stream, after the discharge of such effluents;

   (l)  to make, vary or revoke any order--

   (i)  for the prevention, control or abatement of discharges of waste into streams or wells;

   (ii)  requiring any person concerned to construct new systems for the disposal of sewage and trade effluents or to modify, alter or extend any such existing system or to adopt such remedial measures as are necessary to prevent, control or abate water pollution;

   (m)  to lay down effluent standards to be complied with by persons while causing discharge of sewage or sullage or both and to lay down, modify or annul effluent standards for the sewage and trade effluents;

   (n)  to advise the State Government with respect to the location of any industry the carrying on of which is likely to pollute a stream or well;

   (o)  to perform such other functions as may be prescribed or as may, from time to time, be entrusted to it by the Central Board or the State Government.

   (2)  The Board may establish or recognise a laboratory or laboratories to enable the Board to perform its functions under this section efficiently, including the analysis of samples of water from any stream or well or of samples of any sewage or trade effluents.
