The proposal was discussed in 44th EAC meeting, held on 24- 25/04/2019, wherein, after detailed deliberations, committee insisted for collection of one month baseline data for preparation of addendum to the EIA/EMP report. WCL has requested CMPDI, vide its letter no. WCL/HQ/Environment/8-D/621, dt.09.05.2019, for generation of one month base-line data at the earliest. Hence, base-line data in respect of environmental parameters, like ambient air quality, surface water quality and ambient noise level quality, Air As per observation of EAC meeting regarding Dhankasa UG EC, baseline data on environmental quality has been generated for one month i.e. during May’19 and the same is reported below. Location : Proposed Dhankasa UG coal mine project is located at Tehsil Amarwara, District Chhindwara, Madhya Pradesh in the East of Parasia town. The convenient rail heads for the project is Parasia (45 km) located on the narrow gauge line of South-Eastern Railway. Climate : The climate of the area is tropical. The maximum and minimum temperature range during Summer is 45O C to 27O C and during Winter is 25OC to 4OC. Annual rainfall varies from 1000 mm to 1400 mm. Other Sources of Pollution: Transportation roads, agricultural and local activities, nearby coal mines, vehicular traffic etc also contributes to the pollution. Sampling Location : Ambient Air Quality Monitoring locations : Ambient air quality is monitored at 5 locations viz. proposed Core zone -Bhumkadhana, Charunkhapa village, Jamuniya village, Dighawani village & Banki village as per MoEF guidelines. A total of 45 samples on these five locations, with a frequency of twice a week (24-hrly.), each of PM10, PM-2.5, SO2 and NO2 were monitored during the study period.

Respirable Particulate Matter (PM-10), Fine dust particulate (PM-2.5), Sulphur di-oxide (SO2) and Oxides of nitrogen (NO2) etc. CMPDI, RI-IV, NAGPUR 2 BASELINE DATA GENERATION REPORT DHANKASA UG PM-10 : Ambient air laden with suspended particulates enters the Respirable Dust Sampler through the inlet pipe of sampler by means of a high flow rate blower. As the air passes through the cyclone, coarse, non-respirable dust (size >10 μ) is separated from the air stream by centrifugal forces acting on the solid particles. These separated particles fall through the cyclone's conical hopper and collect in the sampling bottle placed at bottom. The fine dust forming the respirable fraction (size <10 μ) of the Suspended Particulates passes through the cyclone and is carried by the air stream to the Glass Micro Fiber Filter Paper. The Respirable dust (PM-10) is retained by the filter and the carrier air exhausted from the system through the blower. The mass concentration (μg/m3) of Respirable Particulate Matter in the ambient air is computed by measuring the mass of collected particulates and the volume of air sampled. NOX : Determination of oxides of Nitrogen is based on the procedure of "Jacobs and Hochheiser method". In this method the air sample is collected 24 hourly in the field and analysed in the laboratory using spectronic 20 D+ Spectrophotometer. Nitrogen oxides as Nitrogen di-oxide are collected by bubbling air through a solution of Sodium hydroxide and Sodium Arsenite to form a stable solution of Sodium nitrite. The nitrite ion produced during sampling is determined colorimetrically (with the help of Spectrophotometer, measuring absorbance at 540 nm) by reacting the exposed absorbing reagent with Phosphoric acid, Sulphanilamide and N(1- naphthyl) ethylenediamine dihydrochloride. The interference of Sulphur di-oxide is eliminated by converting it to Sulphuric acid with Hydrogen peroxide before analysis. SO2 : Determination of SO2 is based on the procedure of West and Gaeke method. Sulphur di-oxide from the air stream is absorbed in a Sodium tetrachloromercurate solution to form a stable solution of Dichlorosulphitomercurate. The amount of Sulphur dioxide is then estimated by the colour produced when P-Rosaniline hydrochloride is added to the solution. The colour is estimated by a reading of absorbance at 560 nm in the Spectrophotometer. PM-2.5 : Ambient air enters the Fine dust sampler through an omni-directional air inlet designed to provide a clear aerodynamic cut point for particles greater than 10 microns. Particles in the air stream finer than 10 microns proceed to a second impactor that has an aerodynamic cut point at 2.5 microns. The air sample and fine particulates exiting from the PM 2.5 impactor are passed through a 47 mm diameter Teflon filter membrane that retains the PM-2.5. The mass concentrations (μg/m3) of PM-2.5 in the ambient air are computed by measuring the mass of collected particulates and the volume of air sampled. Heavy Metals in Air Samples like Arsenic (As), Lead (Pb), Nickel (Ni), Chromium(Cr) and Cadmium (Cd) have been analysed as per CPCB’s guidelines after digestion of samples in microwave digestor, with the help of Atomic Absorption Spectrophotometer (AAS) with Hydride generation system and Graphite furnace. Water : Water sample is collected and the same is transported to the laboratory for analysis. Water samples have been collected and analysed as per procedures outlined in IS-3025/ APHA for different parameters and the same have been compared with Drinking water standards IS 10500 : 2012. Noise : Ambient Noise level measurement is done with sound level meter during daytime as well as night time. Noise measurements are made at 1.5 m above ground and about 3m from walls, buildings or other sound reflecting sources. The measurements are carried out in such a way that 1 m away from the sources and 1 m away from the edge of the roads. Ambient noise levels are compared with Air Quality Standards in respect of noise for Residential area.
