In a regulatory development aimed at strengthening environmental protections in inland waterways, the Ministry of Ports, Shipping and Waterways has notified the Inland Vessels (Prevention and Containment of Pollution) Amendment Rules, 2025. These rules were informed in exercise of powers under the Inland Vessels Act, 2021. The amendment, which updates the 2022 Pollution Control Framework, came into force on the date of its publication will be published in the Official Gazette after the public comment period yielded no objections or suggestions.

Clarification on Gross Tonnage Measurement
A significant modification relates to the regularization of how inland vessel tonnage is calculated. The revised rule simplifies that for vessels measuring 24 meters or more, gross tonnage is now calculated in accordance with the International Convention on Tonnage Measurement of Ships, 1969. For small vessels less than 24 meters, the Merchant Shipping (Tonnage Measurement of Vessels) Rules, 1987, as amended, shall apply. This change is expected to increase compatibility with international maritime principles.
Upgraded Requirements for Sewage Management
Another significant change relates to on board waste management system. The new rules mandate that all inland vessels producing sewage must fit a suitable sewage treatment plant, bio digester, or holding tank that can adequately accommodate the number of persons on board. However, an exemption has been introduced for vessels plying journeys of less than 60 minutes, reducing the compliance burden for short-distance transport operators.
Correction in Terminology for International Standards Body
To ensure correct legal reference, the phrase "International Organization of Standards" has been corrected to "International Organization for Standardization" (ISO) in the rulebook. This small but significant revision brings the text align with universally accepted terminology and improves the clarity of the regulatory guidance.
Implications for Compliance and Certification
These amendments will directly affect operators obtaining a pollution NOC (No Objection Certificates) for inland vessels. Better clarity and the latest environmental compliance rules mean vessel owners shall ensure strict compliance with these upgraded standards to avoid fines and operational disruptions.
The Inland Vessels (Prevention and Prevention of Pollution) Amendment Rules, 2025 represents a step forward in India’s growth towards sustainable inland water transport. By aligning national regulations with international best practices and strengthening pollution control measures, the government highlights its commitment to environmental protection while supporting safe and compliant maritime operations.
