Why in the News
On 28 January 2026, PIB stated that the government has amended the Uniform Consent Guidelines issued under the Air (Prevention and Control of Pollution) Act, 1981 and the Water (Prevention and Control of Pollution) Act, 1974. These guidelines give a uniform framework for granting, refusing or cancelling Consent to Establish (CTE) and Consent to Operate (CTO) for industries.
Validity of a CTO
Once granted, valid until cancelled
Red-category industries
Consent process time from 120 to 90 days
Micro and small units
CTE deemed on a self-certified application in a notified industrial area
Integrated consent
Air-water consent and authorisations under waste rules in one application
Inspection
Registered environmental auditors besides SPCB officers
CTO fee
States can fix a lump-sum fee for 5 to 25 years

What is the consent system?
State Pollution Control Boards (SPCB) and Pollution Control Committees (PCC) grant consent to industries under the Air and Water laws. According to PIB, the uniform guidelines are for uniformity, transparency and accountability in the management of consent across all states and Union territories.
The main amendments
Validity of a CTO: under the amended guidelines, once a CTO is granted it will remain valid until cancelled. The need for repeated renewal is removed. Compliance with the rules will be checked through periodic inspections.
Time limit: the process period for granting consent to red-category industries has been reduced from 120 days to 90 days.
Integrated consent: SPCBs can grant consent under the Air and Water laws and authorisations under various waste-management rules together on a single shared application.
Micro and small units: such units located in notified industrial areas will be deemed to have CTE on submitting a self-certified application, because an environmental assessment of the land has already been done.
Inspection and siting: now registered environmental auditors certified under the Environment Audit Rules, 2025 can also conduct site visits and compliance verification. In place of rigid minimum-distance criteria, a site-specific assessment based on facts such as proximity to water sources, settlements, monuments and ecologically sensitive areas has been put in place.
Fee: states and Union territories can fix a lump-sum CTO fee for a period of 5 to 25 years. A uniform definition of "capital investment" has been added to Schedule II.
Which conclusions to avoid?
The amendments have not ended the safety conditions of consent. Provisions for refusal or cancellation remain in cases of violation of standards, violation of consent conditions, environmental damage or location in a prohibited area. Also do not assume that consent and environmental clearance (EC) are the same thing. The gazette notification of the Water guidelines (G.S.R. 63(E)) is dated 23 January 2026 and is printed in the extraordinary gazette issue of 27 January 2026. The notification of the Air guidelines was not seen separately, so do not fix its dates on the basis of the Water notification. The PIB release is of 28 January. Keep the dates of the notification, publication and the release separate.

(d) None
See answer and reason
Answer: (b) Only two. Statements 1 and 3 are correct. According to PIB, periodic inspections and provisions for cancellation on violation continue.
Question 2. Consider the following statements:
Statement 1: For micro and small units of notified industrial areas, CTE will be deemed on a self-certified application.
Statement 2: Besides SPCB officers, registered environmental auditors can also conduct site visits.
Statement 3: States can fix a lump-sum CTO fee of 5 to 25 years.
Which of the statements are correct?
(a) Only 1 and 2
(b) Only 2 and 3
(c) Only 1 and 3
