Chapter 4: Water (Prevention and Control of Pollution) Act, 1974

CHAPTER IV: POWERS AND FUNCTIONS OF BOARDS

Section 16: Functions of Central Board

This is the main “Job Description” for the national CPCB.

• (1) Main Function: “…the main function of the Central Board shall be to promote cleanliness of streams and wells in different areas of the States.”
  • Simple Explanation: The CPCB’s “mission statement” is to coordinate the national effort to clean up all water bodies in India.
• (2) Specific Functions: “In particular… the Central Board may perform all or any of the following functions…”
  • (a) Advise Central Govt.: “…advise the Central Government on any matter concerning the prevention and control of water pollution;”
    • Simple Explanation: Act as the chief technical advisor on water pollution for the national government.
    • Practical Example: The Ministry of Environment asks the CPCB to prepare a national report on pollution from the textile industry.
  • (b) Co-ordinate State Boards: “…co-ordinate the activities of the State Boards and resolve disputes among them;”
    • Simple Explanation: Act as the “manager” and “mediator” for all the individual State Boards.
    • Practical Example: The State Boards of Odisha and Chhattisgarh are blaming each other for pollution in the Mahanadi River. The CPCB steps in, conducts a study, and issues a final order telling each state what it must do.
  • (c) Technical Assistance & Research: “…provide technical assistance and guidance… carry out and sponsor investigations and research…”
    • Simple Explanation: Act as the country’s R&D and tech-support center for pollution control.
    • Practical Example: A State Board doesn’t know how to test for a new, complex pesticide. The CPCB provides the testing method (“technical assistance”) and also funds a research project at an IIT to find better ways to treat that pesticide (“sponsor research”).
  • (d) Training: “…plan and organise the training of persons engaged… in programmes for… pollution control…”
    • Simple Explanation: Run training programs for pollution control officials from all over the country.
    • Practical Example: The CPCB hosts an annual “boot camp” to train all the new scientists and engineers hired by the various State Boards on legal procedures and new testing technologies.
  • (e) Mass Media: “…organise through mass media a comprehensive programme regarding the prevention and control of water pollution;”
    • Simple Explanation: Run national public awareness campaigns.
    • Practical Example: The CPCB pays for TV commercials, newspaper ads, and social media campaigns encouraging people to stop idol immersion in rivers or to report polluting factories.
  • (ee) Perform State Board functions: “…perform such of the functions of any State Board as may be specified in an order under… section 18;”
    • Simple Fexplan: This is the power (explained in Sec 18) to take over the job of a failing State Board if the Central Government orders it.
  • (f) Data & Manuals: “…collect, compile and publish technical and statistical data… and prepare manuals, codes or guides…”
    • Simple Explanation: Act as the national library and data center for pollution information.
    • Practical Example: The CPCB publishes the official “National Water Quality Monitoring Data” each year. It also writes the official “how-to” guide, like the “Manual for Effluent Treatment Plants in the Sugar Industry.”
  • (g) Set Standards: “…lay down, modify or annul, in consultation with the State Government… the standards for a stream or well… [Proviso: …different standards may be laid down…]”
    • Simple Explanation: This is a critical power. The CPCB sets the standards (the “target”) for what “clean” means for any river or well in the country. The proviso gives it flexibility to set different standards for different rivers.
    • Practical Example: The CPCB declares that the River Ganga must be clean enough for “Bathing Class” (e.g., very low bacteria). For a river in a heavy industrial area, it might set a “D” or “E” standard (“for industrial use/cooling only”). This power sets the goalposts for all other actions.
  • (h) Nation-wide Programme: “…plan and cause to be executed a nation-wide programme…”
    • Simple Explanation: Create and run large, national-level projects.
    • Practical Example: The CPCB helps plan and execute the “National River Conservation Plan,” a multi-billion dollar project to clean up major rivers across India.
  • (i) Other Functions: “…perform such other functions as may be prescribed.”
    • Simple Explanation: A catch-all clause for any other jobs the Central Government gives it.
• (3) Laboratories: “The Board may establish or recognise a laboratory or laboratories…”
  • Simple Explanation: The CPCB can build its own high-tech labs or officially “recognise” (certify) other expert labs (like at an IIT or CSIR) to do its official work.
  • Practical Example: The CPCB has its main “National Reference Laboratory” in Delhi. If a sample is tested there, its results are legally powerful.

Section 17: Functions of State Board

This is the main “Job Description” for the state-level SPCBs (like the Punjab PCB, Gujarat PCB, etc.). It’s where the day-to-day work happens.

• (1) Functions:
  • (a) State-level Plan: “…to plan a comprehensive programme for the prevention, control or abatement of pollution of streams and wells in the State…”
    • Simple Explanation: To create a “master plan” for cleaning up all rivers, lakes, and groundwater within that state.
    • Practical Example: The MPCB (Maharashtra Board) creates a 5-year plan to clean up the Mula-Mutha River in Pune.
  • (b) Advise State Govt.: “…to advise the State Government on any matter concerning… water pollution;”
    • Simple Explanation: To be the chief advisor on water pollution for the state’s Chief Minister and Environment Minister.
    • Practical Example: The State Government wants to build a new industrial park. It must ask the State Board for advice on the best location to avoid polluting a drinking water source.
  • (c) Collect & Share Info: “…to collect and disseminate information relating to water pollution…”
    • Simple Explanation: To gather data on pollution in the state and share it with the public.
    • Practical Example: The KSPCB (Kerala Board) takes samples from the Periyar River every month and posts the results on its website for the public to see.
  • (d) State Research: “…to encourage, conduct and participate investigations and research…”
    • Simple Explanation: To conduct research on pollution problems that are specific to that state.
    • Practical Example: The Gujarat Board (GPCB) conducts a study on the specific pollution challenges from the thousands of small dye-factories in its state.
  • (e) State Training & Education: “…to collaborate with the Central Board in organising… training… and to organise mass education programmes…”
    • Simple Explanation: To help the CPCB run training events in the state, and to run its own local awareness campaigns.
    • Practical Example: The State Board runs ads in the local language newspaper and on local radio about the ill-effects of water pollution.
  • (f) Inspect & Review Plans: “…to inspect sewage or trade effluents, works and plants… and to review plans, specifications or other data…”
    • Simple Explanation: This is a core power. To inspect existing factories and sewage plants, and (more importantly) to review and approve the designs for any new treatment plants before they are built.
    • Practical Example: A company wants to build a new factory. It must submit its ETP (Effluent Treatment Plant) designs to the State Board. The Board’s engineers will review the plans. After the factory is built, the Board officers will inspect it to ensure it matches the approved plans.
  • (g) Set State Effluent Standards: “…to lay down, modify or annul effluent standards for the sewage and trade effluents… (not being water in an inter-State stream)…”
    • Simple Explanation: This is the State Board’s key power. While the CPCB sets the standard for the river, the State Board sets the standard for the pipe. It decides the exact legal limits (e.g., in mg/L) for pollutants coming out of a factory or sewage plant.
    • Practical Example: The CPCB says the river must be “Bathing Class.” The State Board then creates a rule: “To achieve this, no factory in this state is allowed to discharge effluent with more than 30 mg/L of BOD or 10 mg/L of Ammonia.” This is the “effluent standard.”
  • (h, i, j) Evolve Treatment Methods: These clauses are about finding practical, local solutions.
    • (h) Economical Methods: Find cheap, reliable ways to treat waste suited to the state’s climate and soil.
    • (i) Utilization in Agriculture: Figure out how to safely re-use treated sewage/effluent for farming.
    • (j) Disposal on Land: Develop methods for waste disposal on land (e.g., “evaporation ponds”) in dry areas where there are no rivers to discharge into.
    • Practical Example (for all three): In a dry, agricultural region of the state, the State Board works with a local university to develop a low-cost treatment system that cleans sewage water just enough to be safely used for irrigating cotton crops (i), thus solving a disposal problem (j) with an economical method (h).
  • (k) Stream-Specific Standards: “…to lay down standards of treatment… taking into account the minimum fair weather dilution…”
    • Simple Explanation: This gives the Board the power to be stricter where needed. A factory on a tiny stream must clean its water much more than a factory on a huge river, because the small stream has less “dilution” (less clean water to mix with the waste).
    • Practical Example: Factory A (on the massive Godavari River) and Factory B (on a small local stream) both produce 1000 liters of waste. The Board may allow Factory A to discharge waste with 50 mg/L of a chemical, but force Factory B to treat its water down to 10 mg/L, because the small stream would be destroyed by the 50 mg/L discharge.
  • (l) Make Orders: “…to make, vary or revoke any order— (i) for the prevention… of discharges… (ii) requiring any person… to construct new systems…”
    • Simple Explanation: The power to issue direct, legally-binding orders to any person or factory to stop pollution or to build/fix their treatment systems.
    • Practical Example: The Board inspects a 30-year-old hotel and finds its sewage system is broken. It issues an order under this section: “You are required to construct a new Sewage Treatment Plant within 6 months and connect all your wastewater to it.”
  • (m) Lay Down Effluent Standards: (This is somewhat repetitive of clause (g)).
    • Simple Explanation: This just re-confirms the State Board’s primary power to set the legal limits for all wastewater discharges.
  • (n) Advise on Industry Location: “…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;”
    • Simple Explanation: The power of “industrial siting.” The Board gets to advise the government on where industries should and should not be built.
    • Practical Example: A company wants to build a new chemical factory. The State Board advises the government: “We object to the proposed location because it is in the ‘red’ zone (a critical groundwater recharge area). Please direct the company to build in the approved ‘Industrial Zone’ 20 km away.”
  • (o) Other Functions:
    • Simple Explanation: A catch-all for any other jobs given to it by the State Government or the Central Board.
• (2) State Laboratories: “The Board may establish or recognise a laboratory or laboratories…”
  • Simple Explanation: Just like the CPCB, the State Board can build its own labs or “recognise” (certify) private labs to do its official testing work.
  • Practical Example: The MPCB (Maharashtra) has its own labs in major cities. It has also “recognised” over 100 private environmental labs. A factory can get its monthly sample tested at any of these “recognised” labs, and the report will be accepted by the Board.

Section 18: Powers to give directions

This section is extremely important. It establishes the “chain of command” and the ultimate power structure.

• (1) Chain of Command:
  • (a) Central Govt. > Central Board: “…the Central Board shall be bound by such directions in writing as the Central Government may give to it;”
    • Simple Explanation: The Central Government (e.g., the Ministry of Environment) is the BOSS of the Central Board (CPCB). If the Ministry gives the CPCB a written order, the CPCB must obey it.
  • (b) CPCB & State Govt. > State Board: “…every State Board shall be bound by such directions in writing as the Central Board or the State Government may give to it:”
    • Simple Explanation: The State Board has two bosses: its own State Government (e.g., the state’s Environment Minister) and the Central Board (CPCB). It must obey written orders from either of them.
  • (Proviso): “…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.”
    • Simple Explanation: This solves the “two bosses” problem. What if the State Government orders “Allow this factory to open” but the CPCB orders “Shut that factory down”? The rule is: The conflicting orders are sent to the Central Government in Delhi, which makes the final, binding decision. (In practice, the national rule from the CPCB almost always wins).
    • Practical Example: The CPCB has a national rule against new ‘Red Category’ industries in a certain area. A State Government, wanting investment, orders its State Board to grant a permit. The State Board is stuck. This proviso is its escape: it refers the “conflict” to the Central Government, which will uphold the CPCB’s national rule.
• (2) Power to Take Over: “Where the Central Government is of the opinion that any State Board has defaulted… it may… direct the Central Board to perform any of the functions of the State Board…”
  • Simple Explanation: This is the “nuclear option.” If the Central Government believes a State Board is totally failing at its job (e.g., it’s corrupt, incompetent, or deliberately ignoring pollution), it can order the CPCB (the national board) to take over the State Board’s job.
  • Practical Example: The State Board in State ‘X’ is notoriously corrupt and has let a whole industrial area pollute a river to death. After many warnings, the Central Government issues an order: “The CPCB will now perform all functions of the State ‘X’ Board for the ‘XYZ’ industrial area for one year.” CPCB officials will then fly in, conduct inspections, and issue closure notices, completely bypassing the failed State Board.
• (3) Recovering Costs: “…the expenses… incurred by the Central Board… may be recovered by the Central Board… from the person or persons concerned…”
  • Simple Fexplan: If the CPCB takes over (like in the example above) and has to spend money to do the State Board’s job (like cleaning up a spill), it can recover those costs from the original polluter.
  • Practical Example: The CPCB takes over from the failed State Board, has to pay for an emergency cleanup of a factory’s illegal dump, and then sends the factory a bill for the entire cleanup cost, recoverable as a government debt.
• (4) For removal of doubts: “…directions… would not preclude the State Board from performing such functions in any other area…”
  • Simple Explanation: This just clarifies that a “takeover” might be partial. The Central Govt can order the CPCB to take over one specific task (like managing one river) while letting the State Board continue to do all its other work.
  • Practical Example: The CPCB is ordered to take over the “Ganga pollution” file in Bihar, but the Bihar State Board is still allowed to manage all other rivers and industries in the state.
