5 EXECUTIVE SUMMARY 1.0 Introduction The purpose of environmental monitoring is to assess the quality of various attributes that affects the flora and fauna. In accordance with the quality of these attributes appropriate strategy is to be developed to control the pollution level within the permissible limits. The three major attributes are air, water and noise level. Northern Coalfields Limited (NCL), a Subsidiary company of Coal India Limited is operating Opencast Mines in Singrauli Coalfields, Moher sub-basin having an of 312 Sq.km. Out of which 80 Sq.km on Eastern side lies in Sonebhadra District. of U.P. and rest in Singrauli Dist. of M.P.. NCL has awarded Environmental monitoring work of Singrauli Coalfield to Central Mine Planning & Design Institute Limited (L). The environmental monitoring has been carried out as per the conditions laid down by the MoEF&CC while granting environmental clearance of project, consent letter issued by the respective SPCB, and other statutory requirements. 2.0 Sampling location and rationale 2.1 Ambient air sampling locations The ambient air quality monitoring stations were selected to represent core & buffer zone and further classified as residential and industrial. The rationale has been based on the guidelines stipulated by MoEF&CC, consent letter of SPCB, as well as other statutory requirements. 2.2 Water sampling stations The Water sampling stations were selected for mine sump water, workshop effluent, CHP effluent at inlet and outlet of Effluent Treatment Plant (ETP), Outlet of Sewage Treatment Plant (STP), drinking water supply, well/ Hand pump water and also from receiving streams. 2.3 Noise level monitoring locations Noise levels vary depending on the various activities in mining s. The monitoring of noise level in different locations will be helpful to take appropriate mitigating measures. The noise levels were recorded in mining, workshop and in residential. 3.0 Methodology of sampling and analysis 3.1 Ambient air quality Parameters chosen for assessment of ambient air quality were Suspended Particulate Matter (SPM), Particulate Matter (PM10), Fine Particulate Matter (PM2.5), Sulphur Di-oxide (SO 2 ) and Nitrogen Oxides (NO x ). Respirable Dust Samplers (RDS) were used for sampling of SPM, PM10, SO 2, & NO x and Fine Dust Samplers Job no Executive Summary, Page - 1

6 (PM2.5 sampler) were used for sampling of PM2.5 at 24 hours interval once in a fortnight. As per EC conditions half yearly analysis results for heavy metals such as Pb, As, Hg, Ni & Cr of PM10 in ambient air are also covered in this report. The samples were analysed in Environmental Laboratory of, RI-VI, Jayant. 3.2 Water quality Water samples were collected as per standard practice. The effluent samples and Drinking water samples were collected and analysed for four/five parameters on fortnightly basis. The drinking water samples were collected and analysed for all parameters on quarterly basis. Parameters like ph, Temperature and Dissolved Oxygen were analysed on-site while collecting the samples. Thereafter the samples were preserved and analysed at the field laboratory located at RI-VI Office campus. 3.3 Noise level monitoring Noise level measurements in form of 'LEQ' were taken using Integrated Averaging Sound Level Meter (CR: 812C) during day and night time. Noise levels were measured for about one hour time in day and night time. Noise levels were measured in Decibels, 'A' weighted average, i.e. db(a). 4.0 Results and interpretations 4.1 Air quality It has been seen from the analysis results that the 24 hours average concentration of parameters like SPM, PM10, PM2.5, SO 2 and NO x are mostly within the permissible limits in all sampling locations as per MoEF&CC Gazette Notification GSR 742(E) dt Standards for Coal Mines and National Ambient Air Quality Standard Sometimes the concentration of SPM, PM10 & PM2.5 exceeds the limits due to presence of numbers of thermal powers in the vicinity. 4.2 Water quality The test results indicate that the major parameters compared with MoEF&CC Gazette Notification GSR 742(E) dt Standards for Coal Mines (For 4/5 parameters of drinking and effluent water) & IS.10500/2012 (All parameters of Drinking water) are within permissible limits. 4.3 Noise Level During the noise level survey it has been observed that the noise level in the sampling locations is within the permissible limits prescribed as per MOEF Gazette Notification GSR 742(E) dt Standards for Coal Mines for Industrial Area and Noise pollution (Regulation and Control) Rules, 2000, for residential Area.

7 CHAPTER -I INTRODUCTION 1.0 Any industry and development activities including coal mining is bound to affect environmental attributes. There are positive as well as negative impacts of such operations. For controlling the adverse impacts a regular monitoring is essential. The environmental monitoring is being done as per the guide-lines stipulated by Ministry of Environment Forest and Climate Change (MoEF&CC), Govt. of India. The very purpose of environmental monitoring is to assess the quality of various attributes which affects the environment. As per quality of these attributes appropriate strategy is to be developed to control the pollution level within the permissible limits. The three major attributes are air, water and noise level. Northern Coalfields Limited (NCL), a subsidiary company of Coal India Limited (CIL) is operating Opencast Mines in Singrauli coalfield.

26 CHAPTER - IV NOISE LEVEL QUALITY MONITORING 4.1 Location of sampling sites and their rationale (Refer Fig. No-.II) i) Time Office (NN1). ii) The location is selected to assess the environmental noise quality of working surrounded by workshop, mining face & substation. Nigahi Colony (NN2) The station is located in the Nigahi colony and will represent the ambient noise quality of the residential of the Project. iii) Nandgaon Rehabilitation Site (NN3) The location will represent the ambient noise quality of the residential of Nandgaon rehabilitation site. 4.2 Methodology of sampling and analysis Noise level measurements in form of 'LEQ' were taken using Integrated Averaging Sound Level Meter (CR: 812C) during day and night time. Noise levels were measured for about one hour time in day and night time. Noise levels were measured in Decibels, 'A' weighted average, i.e. db (A). 4.3 Results & Interpretations Ambient noise levels were recorded during day and night time and the observed values were compared with standards prescribed by MoEF&CC. The results of Noise levels recorded during day and night time on fortnightly basis are presented in tabular form along with the applicable standard permissible limits. The observed values in terms of LEQ are presented. The observed values at all the monitoring locations are found to be within permissible limits. Job no Chapter 4, Page - 1
