Pallatana- Silchar 400 kV D/C Transmission Line – Critical issues
Forest Clearance: Approximately 208 locations are falling within forest area (Tripura:81 Km, 200
loc.) and (Assam:4km, 8 loc.). Second stage forest clearance for Assam is yet to be obtained. Replies to queries
raised by MoEF to Assam on 04.10.2010 were forwarded to MoEF on 19th February 2011. The MoEF vide their letter dated 15th April 2011 to Assam Forest department sought further details in respect of the scheme for plantation of dwarf trees and compliance to Forest Rights Act (2006).
Second stage forest clearance for Tripura has been obtained in August 2010 only i.e. approximately 13 months after award of construction contract. Tree felling and construction of line in the forest stretches are in progress. Meanwhile case submitted on 4th March 11 for additional 3 locations falling in forest near GBCCP gantry for which fresh clearance is required.
Only one month is left in the working season
Non-availability of adequate no. of trained gangs for deployment at site by the contractors
