PREFACE In compliance to the Notification issued by the Ministry of Environment and Forest and Climate Change dated 15-01-2016, the District Survey Report of river sand mining for Namakkal District is prepared. Every effort have been made to cover sand mining locations, areas and overview of mining activity in the District with all its relevant features pertaining to geology and mineral wealth in replenishable and non-replenishable areas of rivers, stream and other sand sources. This report will be a model and guiding document which is a compendium of available mineral resources, geographical setup, environmental and ecological setup of the District and is based on data of various departments, study conducted by renowned institutions, published reports and websites. SURVEY REPORT OF NAMAKKAL DISTRICT As per Gazette Notification of 15th January 2016 of Ministry of Environment, Forest and Climate Change, a survey shall be carried out by the District Environment Impact Assessment Authority (DEIAA) with assistance of Water Resources Department, Forest Department, Geology and Mining Department and Revenue Department in the District for preparation for District Survey Report as per sustainable sand mining guidelines to ensure identification of areas of aggradation or deposition where mining can be allowed and identification of areas of erosion and proximity to infrastructural structures and installations where mining should be prohibited and calculation of annual rate of replenishment and allowing time for replenishment after mining in that area. 1 The detailed study has been made through IIT, Madras to cover sand mining locations, area and overview of mining activity in the District with all its relevant features pertaining to geology and mineral wealth, replenishable and non-replenishable areas of rivers, stream and other sand sources. The mineral potential is calculated based on field investigation and geology of the catchment area of the river (or) streams. The area for removal of the mineral in a river or stream is decided depending on geomorphology and other factors. The District Survey Report shall form the basis for application for Environmental Clearance, preparation of reports and appraisal of projects. The report shall be updated once in five years. 2 2.
