The minutes of a meeting of the Expert Appraisal Committee (EAC) on River Valley and Hydroelectric Projects, held in January this year, include the following lines: The work of determining the "... carrying capacity of the Teesta basin with respect to hydropower development was entrusted by MoEF to the Center for Inter-Disciplinary Studies of Mountain & Hill Environment (CISMHE) in 2001, and completed in 2007. Based on the study, MoEF in October 2008 advised the Sikkim Government not go to ahead with the construction of dams and large scale development activities in the area above Chungthang due to ecological and geological sensitivity. This has affected the development of five hydropower projects in the state ... The Sikkim Government has requested for reconsideration of the decision and sought to present their interpretation of the study before the EAC."
This is a giveaway to the tale that I am to narrate. But to know and understand the future implications of what the EAC has finally decided, one needs to step back a bit. At least about 12 years or so.
The river Teesta that flows through Sikkim and north Bengal, is not just the lifeline of the state of Sikkim. It has interconnected within its rapids cultures, livelihoods, and deep spiritual connections. From Bengal the river traverses into Bangladesh where it finally joins the Brahmaputra as a tributary. Like many other Himalayan rivers in India, the Teesta presents a lucrative opportunity for power developers and dam engineers. The fast flowing river and its gorges suggest ample scope for several run-of-the-river energy projects in the river basin. Naturally, there has been no shortage of businesses wanting to exploit this.
Plans for the Teesta
In 1998, the expert committee on River Valley and Hydroelectric Projects was in the process of granting approval to the 510 MW Teesta V Hydro project. The matter had landed before the committee because such approval was required as part of the procedure prescribed under the Environment Impact Assessment Notification, 1994 (since amended in 2006).
According to an investigation report of 2004 by Manju Menon and Neeraj Vagholikar of Kalpavriksh Environmental Action Group, the Teesta V project was an initiative of the National Hydro Power Corporation (NHPC) and was to be the first of the 6-stage 'cascade' plan to harness a total of 3635 MW of hydropower, all over a 175-km section of the Teesta in Sikkim. The proposed run-of-the-river scheme, involved a concrete gravity dam 96.45 m high and 182.5 m long at Dikchu, which would raise the water level upstream before diverting it through a 17.5 km long 'head race tunnel' (HRT) to the powerhouse at Balutar.
The committee first decided that the Teesta V project could not be granted environment clearance unless and until a comprehensive study to determine the carrying capacity of the river was carried out. The purpose of such a study is to ascertain how much development can take place on the river without serious social, ecological and environmental impacts.
However, the Ministry of Environment and Forests (MoEF) and its EAC did not wait for the study to be completed. According to Tseten Lepcha of Affected Citizens of Teesta (ACT, a leading organisation in Sikkim raising concerns with respect to dams on the Teesta River Basin), "In May 1999, following pressure from the Ministry of Power, the Teesta V project was granted clearance. The clearance came with a clear condition that no other project in Sikkim will be considered for environmental clearance till the study on the river's carrying capacity is completed. However, in violation of this condition the clearance for Teesta Stage III project was granted, and therefore that approval is illegal"
Action in Sikkim
The task of carrying out the afore-mentioned study was given to the New Delhi-based Centre for Inter-Disciplinary Studies of Mountain and Hill Environment (CISMHE), and funded by the project proponent NHPC. CISMHE initiated the study in 2001 and took six years to complete it. But MoEF seemed to be in a hurry, and decided not to wait for the completion of the study. It granted approval to five projects on the Teesta River basin, in violation of the conditions prescribed for the Teesta V project, probably under pressure from other Government of India ministries. As the CISMHE study itself admits, "... after the Hon'ble Prime Minister's 50,000 MW initiative in 2003, a number of schemes have been proposed on the Teesta and its tributaries."
The report was candid in pointing out that the river held great potential for the development of power, but it also raised concerns about the ecological sensitivity of the region.
Around the time the study was completed, several local youth associated with the Affected Citizens of Teesta were sitting on the streets of Gangtok in an unending satyagraha. Representatives of the Lepcha tribal community were on an indefinite hunger strike to save Dzongu, their traditional homeland. It was one of the most inspiring youth-led campaigns of recent times, which received both national and international attention. The Lepcha and their supporters were deeply concerned that the free flow of the Teesta would be arrested, and it would impact their identity greatly. They were worried about their lands being acquired for the project, and also concerned about the influx of outside labour for dam construction, which they believed would lead to cultural erosion.
