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 for 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. This DSR has been prepared in conformity with the S O 141 (E), S O 3611 (E) and other sand mining guidelines published by MOEF & CC time to time as well as the requirement specified in WBMMCR, 2016. The purpose of District Survey Report (DSR) is to identify the mining potential areas where mining can be allowed; and also to distinguish areas where mining will not be allowed due to proximity to infrastructural structures and installations, areas of erosion. The DSR would also help to estimate the annual rate of replenishment wherever applicable. Preparation of this DSR involved both primary and secondary data generation. The primary data generation involved the site inspection, survey, ground truthing etc. while secondary data has been acquired through various authenticated sources and satellite imagery studies. Coochbehar district has 128 gram panchayats with 665720 households and a total population of 2819086 people. The area covers around 3387 sq. km. Coochbehar district is located in the northeastern part of the state and bounded by the district of Jalpaiguri and Alipurduar in the north, Dhubri and Kokrajhar district of Assam in the east and by Bangladesh in the west as well as in the south. The district forms part of the Himalayan Terai of West Bengal. Coochbehar is a flat region with a slight southeastern slope along which the main rivers of the district flow. Most of the highland areas are in the Sitalkuchi region and most of the low- lying lands lie in Dinhata region. The rivers in the district of Coochbehar generally flow from northwest to southeast. Six rivers that cut through the district are the Teesta, Jaldhaka, Torsha, Kaljani, Raidak and Gadadhar.
