http://JUDIS.NIC.IN SUPREME COURT OF INDIA complied with. They argued, based on the clearance certificate that the conditions have to be carried out pari passu with the engineering works. And prayed that the impoundment shall not be allowed till its compliance. The respondents deny this contention and submit that the environmental plans connected with the project are to be implemented pari-passu with the implementation of engineering works and submit that various actions have already been initiated in this regard. On the question of Catchment Area Treatment, it is contended that the Remote Sensing Application Centre, U.P. made a report identifying the critically degraded areas conforming to the very high and high erodability classification has been received and submitted to MoEF. Adequate financial provisions have been made as per requirements depending on the availability of the funds with THDC for the proposed treatment and at the time of filing of the first of the counter affidavits as late as in July 1992, 17,700 hectares have already been treated. Rehabilitation programme has also been taken up in consultation with the local representatives of the affected population and the Administrative Staff College of India, Hyderabad. Similar rehabilitation package as that for Tehri is proposed for families affected by Koteshwar Dam as well as for those living on the rim of the reservoir. The Government of U.P. had indicated to the MoEF that implementation of plans is going on and considerable work has already been completed in this area. Studies had been conducted by the Botanical Survey of India and Zoological Survey of India regarding flora and fauna and action plans were under preparation. Water Quality Maintenance was being modelled on a report to be made by the Roorkee University and it was assured that Water Quality Monitoring Station at appropriate time during the construction will be set up. A disaster management plan has been submitted by the THDC to the Government of India. On 23.3.1990, by issuance of a notification, the Government of U.P. has set up the Bhagirathi River Valley Authority. Therefore, it is contended that formulations of environmental action plans and their implementation is being carried out pari-passu with the construction of engineering works. While 10% of expenditure over the estimated cost had been incurred on the project works, the corresponding expenditure incurred on rehabilitation works and the environmental measures was 41% and 52% of the estimated cost respectively as in March 1992. It is, therefore, contended that the conditional clearance given to the respondents has not lapsed. Even the Government proceeded on the basis that the project was still a going project and, therefore, appointed two expert committees even as late as in 1996 to examine - one on the safety aspect and the other on environment and rehabilitation aspects. As late as on 14.3.2002 an affidavit has been filed on behalf of the Government of India. It is pointed out therein that the MoEF while according environmental clearance to the Project had laid down certain conditions in their letter dated July 19, 1990. These conditions had, inter alia, enumerated certain studies which were to be carried out and based on their findings, action plans had to be drawn up for execution pari-passu with the construction of the project. It is also pointed out that all the required studies had been completed and their reports submitted to the MoEF and these studies indicated that no environmental damage would be caused by the construction of the project which cannot be remedied by adoption of appropriate measures and for this purpose, action plans wherever called for have been and are being formulated for environmental upgradation. It is further pointed out that implementation of the project and the action being taken in regard to environmental concerns at the cost of the project would lead to improvement in the existing environment/ ecology of this region. HRC was constituted to examine the implementation of various conditions of environmental clearance except that relating to safety aspects and design of the Tehri Dam and suggest additional or improved environmental safeguards, if any, based on data and information now available. HRC, after examining various documents and discussions with experts, officials and Page 12 of 37
