2.0 DETAILS OF MONITORING/SAMPLING STATIONS To carry out the Environmental Data Generation programme, CEMC in due consultation with OMC has identified different location to collect the samples for Air & Water Environment in and around the mining lease. The details of stations identified are as follows. The locations of monitoring stations are shown in Plate I & II.

Ambient Air Quality (AAQ) The prime objective of the ambient air quality study is to establish the existing ambient air quality in and around the mining lease area. The existing ambient air quality was monitored at six (6)

locations. Monitoring was carried out for Particulate Matter (PM10), Particulate Matter (PM2.5), Sulphur Dioxide (SO2), Oxides of Nitrogen (NOX) and Carbon Monoxide (CO). The monitoring is carried out as per the guideline stipulated by Central Pollution Control Board.

Noise Level (NL & WZNL) Noise level monitoring was carried out in nearby areas termed as Ambient Noise Level as well as work zone area termed as Work Zone Noise Level. Six Ambient Noise Stations have been identified and is carried out for 24 hours on hourly interval once in a month. Three locations have been identified in working area within the mining lease and is measures on hourly interval for 8 hours once in a month.
