Tamil Nadu has urged the empowered committee headed by former Chief Justice of India A. S. Anand to reject the Detailed Project Report submitted by Kerala on a new dam across the Mullaperiyar as the existing structure is safe.

In its response to Kerala's application asking the committee to consider the proposal for the new dam, the Tamil Nadu Government stated: “The State of Kerala has submitted the DPR in a suo motu assumption that the existing dam is unsafe both hydrologically and structurally. In contrast, the existing dam has been proved to be safe on both counts and hence the need for a new dam to replace the existing dam does not arise.”

The application filed by advocate G. Umapathy said: “The DPR for the new dam suffers from lack of complete investigations. The State of Kerala has filed an incomplete report which cannot form the basis for any dam and ought to be rejected by the empowered committee.”

Tamil Nadu said, “As the existing dam has been strengthened and well maintained and monitored to be good and safe both on hydrological and structural safety parameters, there is no need for a new dam, which in any case would be unviable keeping in view the environmental and ecological issues.”

“The attempt of Kerala in filing the present DPR is not a bona fide action actuated by any genuine concern with regard to the safety of the existing dam, but is an attempt to deprive Tamil Nadu of the right to the waters of the Mullaperiyar dam under the 1886 agreement, as ratified by the supplemental agreements of 1970.

The DPR seeks to restrict the Full Reservoir Level (FRL) to +136 ft., thereby defeating the rights of Tamil Nadu to water up to the contour line of +155 ft., guaranteed under the agreement of 1886 as ratified by the supplemental agreements of 1970,” it added.
