Total Suspended Particulate Matter (TSPM), PM2.5, PM10, 502 and NOx

Total Suspended Particulate Matter i.e., PM2.5 & PM10 present in ambient air is sucked through the cyclone. Coarse and non-respirable dust is separated from the air stream by centrifugal forces acting on the solid particles. These separated particulates fall through the cyclone's conical hopper and collect in the sampling cap placed at the bottom. The fine dust «10 microns) forming the respirable fraction of the TSPM passes the cyclone and is retained by the filter paper. A tapping is provided on the suction side of the blower to provide suction for sampling air through a set of impingers. Samples of gases are drawn at a flow rate of 0.2 liters per minute (Ipm).

TSPM and RPM have been estimated by gravimetric method. Modified West and Gaeke Method (IS-5182 Part-II, 1969) has been adopted for estimation of S02' Jacobs-Hochheiser method (IS-5182 Part-IV, 1975) has been adopted for the estimation of NOx; the details are given in Table-3.3.

Calibration

Calibration charts have been prepared for all gaseous pollutants. The calibration is carried out whenever new absorbing solutions are prepared. The following techniques have been used for ambient air quality monitoring:

) 3.2 Noise Level Monitoring

( ) The noise levels were monitored in eight locations in and around the plant area during the year 2014 -2015 on monthly basis.

3.2.1 Identification of Sampling Locations

A preliminary reconnaissance survey has been undertaken to identify the major noise( ) generating sources in the area. Noi~e at different noise generating sources has been identified based on the activities in the village area, ambient noise due to industries and ( ) traffic and the noise at sensitive areas like hospitals and schools. The noise monitoring has been conducted for determination of noise levels at 4 locations in the study area (out side of plant area), 4 locations inside of the plant area. The environment setting of each noise monitoring location is given in Table-3.6 and depicted in Figure-3.2.

3.2.2 Method of Monitoring

Sound Pressure Level (SPL) measurements were measured at all locations; one reading for every hour was taken for 24 hours. The day noise levels have been monitored during 6 am to 10 pm and night levels during 10 pm to 6 am at all the locations covered in 10-km radius of the study area.

3.2.3 Parameters Measured During Monitoring l)

For noise levels measured over a given period of time interval, it is possible to describe () important features of noise using statistical quantities. This is calculated using the percent of the time certain noise levels are exceeding the time interval. The notation for() the statistical quantities of noise levels are described below: • LlO is the noise level exceeded 10 per cent of the time;( ) • Lso is the noise level exceeded 50 per cent of the time; and • Lgo is the noise level exceeded 90 per cent of the time. ( )

Equivalent Sound Pressure Level (Leq ):()

The Leq is the equivalent continuou's sound level which is equivalent to the same sound () energy as the actual fluctuating sound measured in the same period. This is necessary because sound from noise source often fluctuates Widely during a given period of time.() This is calculated from the following equation:

(2) (L iO - LgO)2

Leq = Lso + ----------­® 60

Lday is defined as the eqUivalent noise level measured over a period of time during day ® (6 am to 10 pm). Lnlght is defined as the eqUivalent noise level measured over a period of time duringCD night (10 pm to 6 am). A noise rating developed by EPA for specification of community noise from all tbe sources is the Day-Night Sound Level, (Ldn).

® Day-Night Sound Level (Ldn):

() The noise rating developed for community noise from all sources is the Day-Night Sound Level (Ldn). It is similar to a 24 hr eqUivalent sound level except that during night time period (10 pm to 6 am) a 10 dB (A) weighting penalty is added to the instantaneous sound level before computing the 24 hr average. This night time penalty is added to account for the fact that noise during night when people usually sleep is judged as more annoying than the same noise during the day time. The Ldn for a given location in a community may be calculated from the hourly Leq's, by the following equation:

= 10 log {lj24[16(10 Ld/l0) + 8 (10(Ln+l0)/10)]} Ldn

Where Ld is the equivalent sound level during the day time (6 am to 10 pm) and Ln is the eqUivalent sound level during the night time (10 pm to 6 am).

3.2.4 Presentation of Results

The statistical analysis is done for measured noise levels at 10 locations for once during study period. The parameters are analyzed for L day , Lnight, and Ldn . These results are tabulated in Table-3.7, and details of noise measurement carried out inside of the plant area in 4 locations are given in Table-3.8.
