New Delhi: In an important judgment, the Supreme Court has linked the quantum of sand mining to the replenishment capacity of the river, a decision that prevents the eroding of the riverbeds, as a result it is difficult to grant the leases for the extraction of raw materials a major construction from the banks of the river.Taking the regulatory regime for sand mining one step ahead, a bench of Justice PS Narasimha and as Chandras said that the extraction of sand from the riverbeds should be with the ability to re -fill the river’s ability, with the ability to grow trees in a forest for wood flying in a forest.The bench said, “The way forest conservation requires assessing the growth rate of the tree before allowing wood harvesting to ensure that the decline of trees does not exceed the growth of the tree, a replenishment study enables us to make an informed decision whether sand mining can be allowed without reducing the natural balance of rivers.”A bench headed by Justice Narasimha, referring to its decision earlier this year, said that a valid and subsistence District Survey Report (DSR) is mandatory for the grant of environmental withdrawal (EC) for sand mining. “The purpose and purpose of preparing such a district survey report is to locate the place for sand mining after calculating the annual rate of replenishment to allow mining in the area scientifically,” said this.The bench said, “Therefore, it is forced to believe that a DSR is valid and only when a proper replenishment study is done,” the bench said, the absence of a replenish study makes a DSR fundamentally defective.It came from the bench rejecting the appeal by the ruling J&K Govt and the National Highways Authority of India, which challenged a National Green Tribunal order, which separated the permission for sand mining, without a proper replenishment study, for the proposal of a project, who honored the construction of a four-lan bayn bayon bay-lalen bay-lalen bay-lalen bay-line around the city.
