Alipurduar West Bengal 1. Preface The need for District Survey Report (DSR) have been necessitated by MoEF & CC vide there Notification No. 125 (Extraordinary, Part II Section 3, Sub-section ii), S.O. 141 (E), dated 15th January 2016. The notification was addressed to bring certain amendments with respect to the EIA notification 2006 and in order to have a better control over the legislation. District level committee’s have been introduced in the system. As a part of this notification, preparation of District Survey Reports has been introduced. Subsequently, MOEF & CC has published Notification No. 3611 (E), dt. 25th July, 2018 regarding inclusion of the “Minerals Other than Sand” and format for preparation of the DSR has been specified. Monitoring Guidelines for Sand Mining (EMGSM) January 2020, Issued by Ministry of Environment, Forest and Climate Change is prepared in consideration of various orders/directions issued by Hon’ble NGT in matters pertaining to illegal sand mining and also based on the reports submitted by expert committees and investigation teams.
