1.0 INTRODUCTION

Odisha Mining Corporation Limited (OMCL), a Government of Odisha undertaking has engaged M/sEcological Development Consultancy Pvt. Ltd. (EDCPL), Bhubaneswar, Odisha for carrying outEnvironmental Monitoring for their different mine leases in the district of Jajpur, Keonjhar andSundergarh.

Environmental Monitoring includes monitoring of various environmental attributes such as AmbientAir Quality, Work Zone Air Quality, Noise Level, Water Quality, Waste Water Quality, VehicularEmission and Soil Quality. Apart from these, various other activities such as suggestions to control thepollution, conducting various kinds of audits are also a part of this programme.

2.0 MONITORING DESCRIPTION

In order to assess the pollution level in and around the mining lease, different environmental attributessuch as meteorology, air quality, water quality, soil quality and noise level are being monitored. Themonitoring is carried out as per the CPCB guideline and every care has been taken for preservation andtransportation of samples to the respective laboratory. M/s EDCPL has set up a site laboratory equippedwith adequate instruments and equipments to monitor and analyze all the parameters of Air Quality i.e.PM2.5, PM10, SO2, NOX&CO and few physic-chemical parameters ( 10 parameters) of water samples.For other parameters of water& Soil, the samples are sent to EDCPL’s Main Laboratory atBhubaneswar. The locations of monitoring stations are shown in Plate I & II.

2.1 Meteorology

An Automatic Weather Monitoring Station is installed at the rooftop of OMC office (21002’1.09” N;85048’8.46”E) to collect the meteorological data on hourly basis continuously.

The parameters monitored at the meteorological station were Temperature, Relative Humidity, WindSpeed, Wind Direction and Rainfall. These parameters were recorded at weather monitoring stationusing the respective sensors.

2.2 Ambient Air Quality

The prime objective of the ambient air quality study is to establish the existing ambient air quality inand around the mining lease area. The existing ambient air quality was monitored at six (6) locations.The locations were identified after due consultation of the OMCL officials. Monitoring was carried out forParticulate Matter (PM10), Particulate Matter (PM2.5), Sulphur Dioxide (SO2), Oxides of Nitrogen (NOX)and Carbon Monoxide (CO). The PM10 &PM2.5 was monitored for 24 hourly, while SO2 and NOxweremonitored on 4 hourly basis for 24 hours at each sampling location and CO was monitored using the COMonitor for 1 hr in a day in each monitoring station twice in a week, for a month. Details about Air QualityMonitoring locations are given in Table No. 2.1.
