          Not withstanding anything contained in this Act where any Joint Board is constituted under Section 13 -
          (a)     the Government of the State for which the Joint Board is constituted shall be competent to give any
                    direction under this Act only in cases where such direction relates to a matter within the exclusive
                    territorial jurisdiction of the State;
          (b)     the Central Government alone shall be competent to give any direction under this Act where such
                    direction relates to a matter within the territorial jurisdiction of two or more States or pertaining to a

CHAPTER IV
POWERS AND FUNCTIONS OF BOARDS

16.     Functions of Central Board
     (1)     Subject to the provisions of this Act, the main function of the Central Board shall be to promote
               cleanliness of streams and wells in different areas of the States.

     (2)     In particular and without prejudice to the generality of the foregoing function, the Central Board may
               perform all or any of the following functions, namely:--
               (a)     advise the Central Government on any matter concerning the prevention and control of water
                         pollution;
               (b)     co-ordinate the activities of the State Boards and resolve disputes among them;
               (c)     provide technical assistance and guidance to the State Boards, carry out and sponsor
                         investigations and research relating to problems of water pollution and prevention, control or
                         abatement of water pollution;
               (d)     plan and organise the training of persons engaged or to be engaged in programs for the prevention,
                         control or abatement of water pollution on such terms and conditions as the Central Board may
                         specify;
               (e)     organise through mass media a comprehensive programme regarding the prevention and control of
                         water pollution;
               (ee)   perform such of the functions of any State Board as may be specified in an order made under sub-
                        Section (2) of Section 18;
               (f)      collect, compile and publish technical and statistical data relating to water pollution and the
                         measures devised for its effective prevention and control and prepare manuals, codes or guides
                         relating to treatment and disposal of sewage and trade effluents and disseminate information
                         connected therewith;
               (g)     lay down, modify or annul, in consultation with the State Government concerned, the standards for a
                         stream or well: Provided that different standards may be laid down for the same stream or well or for
                         different streams or wells, having regard to the quality of water, flow characteristics of the stream
                         or well and the nature of the use of the water in such stream or well or streams or wells;
               (h)     plan and cause to be executed a nation-wide programme for the prevention, control or abatement of
                         water pollution;
               (i)     perform such other functions as may be prescribed.

     (3)     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.

17.     Functions of State Board
     (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 in 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 or 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)     lay down, modify or annul effluent standards for the sewage and trade effluents and for the quality of

                         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
                         specially 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 discharge 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 advice 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.

18.     Powers to give directions
     (1)     In the performance of its functions under this Act --
               
(a)     the Central Board shall be bound by such directions in writing the Central Government may give to
                         it; and
               
(b)     every State Board shall be bound by such directions in writing as the Central Government or the
                         State Government may give to it:
                         
Provided that where a direction given by the State Government is inconsistent with the direction
                         given by the Central Board, the matter shall be referred to the Central Government for its decision.

     (2)     Where the Central Government is of the opinion that and State Board has defaulted in complying with any
               directions given by the Central Government under sub-Section (1) and as a result of such default a grave
               emergency has arisen and it is necessary or expedient so to do in the public interest, it may, by order,
               direct the Central Board to perform any of the functions of the State Board in relation to such area for
               such period and for such purposes, as may be specified in the order.

     (3)     Where the Central Board performs any of the functions of the State Board in pursuance of a direction
               under sub-Section (2), the expenses, if any, incurred by the Central Board with respect to performance of
               such functions may, if the State Board is empowered to recover such expenses, be recovered by the
               Central Board with interest (at such reasonable rate as the Central Government may, by order, fix) from
               the date when a demand for such expenses is made until it is paid from the person or persons concerned
               as arrears of land revenue or of public demand.

     (4)     For the removal of doubts, it is hereby declared that any directions to perform the functions of any State
               Board given under sub-Section (2) in respect of any area would not preclude the State Board from
               performing such functions in any other area in the State or any of its other functions in that area.


CHAPTER V
PREVENTION AND CONTROL OF WATER POLLUTION

19.     Power of State Government to restrict the application of The Act to certain areas
     (1)     Notwithstanding contained in this Act, if the State Government, after consultation with, or on the
               recommendation of, the State Board, is of opinion that the provisions of this Act need not apply to the
               entire State, it may, by notification in the Official Gazette, restrict the application of this Act to such area
               or areas as may be declared therein as water pollution, prevention and control area or areas and
               thereupon the provisions of this Act shall apply only to such area or areas.

     (2)     Each water pollution, prevention and control area may be declared either by reference to a map or by
               reference to the line of any watershed or the boundary of any district or partly by one method and partly
               by another.

     (3)     The State Government may, by notification in the Official Gazette-
               
(a)     alter any water pollution prevention and control area whether by way of extension or reduction; or
               
(b)     define a new water pollution, prevention and control area in which may be merged one or more water
                         pollution, prevention and control areas, or any part or parts thereof.

20.     Power to obtain Information
     (1)     For the purpose of enabling a State Board to perform the function conferred on it by or under this Act, the
               State Board or any officer empowered by it in that behalf, may make surveys of any area and gauge and
               keep records of the flow or volume and other characteristics of an stream or well in such area, and may
               take steps for the measurement and recording of the rainfall in such area or any part thereof and for the
               installation and maintenance for those purposes of gauges or other apparatus and works connected
               therewith, and carry out stream surveys and may take such other steps as may be necessary in order to
               obtain any information required for the purposes aforesaid.

     (2)     A State Board may give directions requiring any person who in its opinion is abstracting water from any
               such stream or well in the area in quantities which are substantial in relation to the flow or volume of that
               stream or well or is discharging sewage or trade effluent into any such stream or well, to give such
               information as to the abstraction or the discharge at such times and in such form as may be specified in
               the directions.

     (3)     Without
