INTRODUCTION East Khasi HillsDistrict is one of the 11(eleven) districts in the state of Meghalaya with Shillong being it’s headquarter. The District forms a central part of Meghalaya and covers a total geographical area of 2,748 Sq. Kms. lying approximately between 25°07” & 25°41” N Latitude and 91°21” & 92°09” E Longitude . Bounded by the plain of Ri-Bhoi District to the North and gradually rising to the rolling grasslands of the Shillong plateau interspersed with river valleys, then falls sharply in the Southern portion forming a deep gorges and ravines in Mawsynram and Shella- Bholaganj, community and rural development block, bordering Bangladesh. To the East itis bounded by Jaintia Hills District and the West Khasi Hills District to the West. The district comprises of ten Community and Rural Development blocks at present viz., KhadarshnongLaitkroh, Mawkynrew, Mawphlang, Mawryngkneng, Mawsynram, Mylliem, ShellaBholaganj, Sohiong, Mawlai and Mawpat and two civil sub-divisions i.e., Sohra and Pynursla. The population of the district as per Census 2011 is 8, 24,059 with a density of 292 per Sq. Kms covering a total of 1, 60,832 households (Excluding Institutional Households) and the literacy rate is 84.70%. The Principal language is Khasi, Jaintia&Garo with English as an official language. The main occupation of the population in the district is agriculture. Shillong is well connected by road with other places in the district as well as with the rest of the Meghalaya and Assam. Shillong is connected by road with all major north eastern states. Two major National Highways pass through East Khasi Hills District National Highway 40 connects Shillong to Jorabat, Assam in the north and extends southwards to Dawki, at Bangladesh border and National Highway 44 connects Shillong to states of Tripura and Mizoram. Mining of sand, gravel, stones and boulders from riverbeds and riverbanks has seen an unprecedented rise in the district as the demand is high in various construction works. With the soaring in demandthis has led to the unregulated and large-scale mining of sand, gravel and stones from riverbeds and riverbanks led to various environmental and social impacts. Riverbed mining causes erosion and often leaves the river-plains much more vulnerable to flooding because it allows loose landmass to be washed downstream, especially during monsoons. This type of mining can also cause salinity intrusion into the rivers, damaging riverine ecosystems,it also causes several alterations to the physical characteristics of both the river and riverbed. These can severely impact the ecological equilibrium of a river and damage plants, animals and riparian habitats. Although sand is a naturally occurring material as a result of weathering process but now it has reached a level of threatening the environment and the ecosystem.In 2013, the NGT Principal 1 Bench, New Delhi OA No. 171 of 2013issued direction to ‘restrain any person, company, authority to carry out any mining activity or removal of sand, from river beds anywhere in the country without obtaining environmental Clearance from MoEF/SEIAA and license from the competent authorities. Similarly, the Supreme Court of India in the case of Deepak Kumar Vs. State of Haryana clearly stated that sand mining on either side of the rivers, upstream and in-stream, is one of the causes for environmental degradation and also a threat to the biodiversity. It had also ordered that mining activity even in less than 5 ha is to obtain Environment Clearance for MoEF /SEIAA.The Government of India therefore in 2016 come up with the Sustainable Sand Mining Management Guidelines to ensure environmentally sustainable mining under supervision of the district authorities. To facilitate systematic, scientific and planned utilization of mineral resources and to streamline mineral based development of the State, keeping in view, protection of environment, health and safety of the people in and around the mining areas and in exercise of the powers conferred by Section 15 of the Mines and Minerals (Development and Regulation )Act,1957 the Government of Meghalaya has therefore come up with the Meghalaya Minor Minerals Concession Rules, 2016to regulate the grant of mining leases and quarry permits in respect of the mining of minor minerals in the State and according to the Ministry of Forests, Environment and Climate Change EIA Notification dt.25th July, 2018 District Survey Report is to be prepared for every district in order to identify the areas of aggradations or depositions where mining can be allowed, 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. Therefore, the District Task Force Committee, East Khasi Hills District has made every effort 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 in the district to be incorporated in the report.This reportwill bea model and guiding document which is a compendium of available mineral resources, geographical set up, environmental and ecological set up of the district and is based on field survey, dataprovided by various departments, published reports, journals and websites. It will form the basis for evaluation of the application for environmental clearance, preparation of reports and appraisal of projects related to mining activity in the district. The Report will be updated once every five years. 2 2. OVERVIEW OF MINING ACTIVITY IN THE DISTRICT Meghalaya is endowed with sizeable deposits of a number of valuable minerals. Coal, limestone, uranium, granite, kaolin, clay and glass sand are the principal minerals. A brief account of mineral resources is as follows: Sl Minerals Reserves in the Grade Major places of occurrence no. State 1 Coal 576 Million Sub-bituminous, Meghalaya coal, which is tertiary tonnes high calorific coal, is generally sub-bituminous in value and high composition. The prominent sulphur content coalfields of the State are West Darrangiri, Siju, Pendengru- Balpakram in the South Garo Hills district; Borsora Langrin and Shallang in the West Khasi Hills district; East Darrangiri partly in West Khasi Hills and partly in East Garo Hills; Mawlong-Shella and Sohra-Cherrapunjee in the East Khasi Hills district and Bapung- Sutnga in the Jaintia Hills district. 2 Limestone 9304 million Cement An extensive bed of limestone tones metallurgical and occurs in the Southern part of the chemical State from Jaintia Hills in the East and Garo Hills in the West.
