    This condition was complied during the construction stage. Bank and bed protection measures such as lining with sand bags, geo-textile and stones were also carried out in the river crossing locations.

    (vi) Pipeline wall thickness and minimum depth of burial at river crossings and casings at rails, major road crossings shall be in conformity with ANSI/ASME requirements.

    This condition was compiled during the construction project stage.

    (vii) The company shall follow horizontal drilling technique for laying of pipeline while passing through major irrigation canal and perennial rivers.

    During construction stage, horizontal drilling technique was followed (viz. CLX-3) for all major crossing locations.

    (viii) The project authorities shall plant a minimum of 10 trees for every tree cut along the pipeline route in consultation with the local DFO (s). This will be in addition to the compensatory afforestation. Approval under Forest (Conservation) Act, 1980 shall also be obtained for forest area falling under the pipeline route before initiating construction of the pipeline in the forest area.

    Plantation activities are being done in a phased manner in partnership with Forest Department and NGOs. In total 23,840 trees were cut along the pipeline corridor route. Tree saplings of 20,49,48 no’s have been planted so far in lieu of compensatory plantation.
