Coastal Regulation Zone interpretation upheld for pipeline and port transfer permissions under the approved management plan.

The approved Coastal Zone Management Plan for Tamil Nadu, 1996 governed CRZ identification unless validly modified, so the later demarcation exercise could not override it. On that plan, the Uppanar river crossing and its banks were not shown as part of CRZ-III, and no separate environmental clearance was required for laying the pipeline beneath that portion. The paragraph 2(ii) exception in the Coastal Regulation Zone Notification, 1991 was construed purposively to cover transfer of hazardous substances in or through port areas, avoiding an unworkable result. On that construction, the environmental clearance and allied permission for the pipeline and marine terminal facility were sustained.

Issues: (i) Whether the Uppanar river and its banks at the point where the pipelines pass fall within the Coastal Regulation Zone, so as to require environmental clearance for laying the pipelines beneath the river. (ii) Whether the exception in paragraph 2(ii) of the Coastal Regulation Zone Notification, 1991 permits transfer of hazardous substances from ships to ports, terminals and refineries in or through port areas, and whether the permission granted to the project was valid.

Issue (i): Whether the Uppanar river and its banks at the point where the pipelines pass fall within the Coastal Regulation Zone, so as to require environmental clearance for laying the pipelines beneath the river.

Analysis: The approved Coastal Zone Management Plan for Tamil Nadu, 1996 remained operative for identification and classification of coastal regulation areas. The later demarcation exercise could not supersede the approved plan in the absence of a valid modification. On the materials before the Court, the banks of Uppanar river where the pipelines cross were not shown as forming part of the Coastal Regulation Zone, and the approval granted by the Ministry related only to the coastal stretch abutting the sea where the onshore pipeline passed through the regulated area.

Conclusion: The Uppanar river crossing did not fall within CRZ-III on the approved plan, and no separate environmental clearance was required for that portion of the pipeline.

Issue (ii): Whether the exception in paragraph 2(ii) of the Coastal Regulation Zone Notification, 1991 permits transfer of hazardous substances from ships to ports, terminals and refineries in or through port areas, and whether the permission granted to the project was valid.

Analysis: The prohibition on manufacture, handling, storage and disposal of hazardous substances was held subject to the exception introduced for transfer from ships to ports, terminals and refineries. To avoid an unworkable and absurd result, the expression "in the port areas" was construed purposively as meaning "in or through the port areas". That construction was consistent with the regulatory scheme permitting pipelines and conveying systems in the Coastal Regulation Zone. The environmental clearance and the consequential permission by the Executive Engineer were therefore sustained.

Conclusion: The exception covered the transfer in or through port areas, and the permission granted to the project was valid.

Final Conclusion: The challenge to the project failed, and the Court declined to interfere with the environmental clearance and allied permissions for the pipeline and marine terminal facility.

Ratio Decidendi: An approved Coastal Zone Management Plan governs CRZ identification unless validly modified, and a statutory exception must be construed purposively so as to advance its object and avoid absurdity.
