Thiruvananthapuram: Union Ministry of Environment and Forests has given nod to carry out a feasibility study for the new dam on Mullaperiyar.
Permission has also been given to conduct an environmental impact assessment for constructing the new dam. It was also directed to conduct a study within 10 km of the area.
The Kerala government had informed the Centre earlier that more forest would not be lost when the new dam is constructed.
Reiterated that the 119 year old dam was not safe, Kerala has been demanding a new dam on Mullaperiyar for quite some time.
The Supreme Court in May had allowed Tamil Nadu to increase the water level from 136 feet to 142 feet and said that the dam was safe.
For the first time in many years - following the heavy rains in and around the dam site and Tamil Nadu's decision not to draw the water to the Vaigai dam - the water level was pegged at 142 feet.
Kerala and Tamil Nadu have been at loggerheads over the dam, built under an 1886 accord between the then Maharaja of Travancore and then British regime.
Though the dam is located in Kerala, it is owned, maintained and operated by Tamil Nadu.
