Andaman Lakshadweep Harbour Works Extension of Hope Town Wharf, Port Blair Harbour, A&N Islands Doc-1 (Chapter 3.0) Baseline Status during Non-Rainy Season 3.1 Study Area The monitoring stations identified within the study area of 10 km radius are shown in Fig. 3.1. As there were rains in December 2016 in A&N Island, the One Month Data Collection directed by MoEF&CC was carried out in January 2017. The services of M/s. Ekdant Enviro Lab, an accredited Laboratory (Ref. No. T-1575) by the National Accreditation Board for Testing and Calibration Laboratories (NABL) were utilised for the monitoring. Indane Bottling Plant and Solar (5 MW) and Diesel Power Plants (20 MW of Suryachakra at Bamboo Flat, Power Plants at Chatham and Phoenix Bay-20 MW) exist in the Project vicinity. However, Ships & Inter-island Boats movements, traffic movements in Port Blair Town and in ATR/NH-223 are the sources of air pollution in the study area though some Green and Orange Category Industrial activities in Dollygunj and Mithagari Industrial Estates. 3.2 Micrometeorology The abstract of collected hourly meteorological data (from Chatham Port Control Tower-PCT) are presented in Table 3.1. During the monitoring month : v Predominant winds were from ENE and ESE directions. v Wind velocity readings were ranging from 0.4 kmph to 23.1 kmph. v Calm condition prevailed for about 29.72% of times. v Winds in the velocity range of 1.6-11 kmph were predominant. v The temperature values were ranging from 19.5 oC to 31.5 oC with a mean value of 27.4 oC. v The relative humidity values were ranging from 44% to 97%. v The mean atmospheric pressure value was computed as 758.5 mm of mercury. v Clear and Partly Cloudy skies was observed most of the times. v There were 13 rainy days during the monitoring month with the total rainfall of 79.5 mm. The monitored meteorological data were found to be in compliance with local weather phenomena. 3.3 Ambient Air Quality All 12 AAQ parameters were monitored in compliance with NAAQ norms. During the study, each 80 samples were collected, analysed and reported. The monitored ambient air quality data are presented in Tables 3.2-3.11. The abstract of those monitored data is given as Table 3.12 and the ambient air quality status in the study area as Table 3.13. On the synthesized data, the following observations are made : PM2.5 : The minimum and maximum PM2.5 values monitored in the Study Area was 6 ug/m3 and 38 ug/m3 with the mean value of 20.5 ug/m3 against the NAAQ Norm value of 60 ug/m3.

Andaman Lakshadweep Harbour Works Extension of Hope Town Wharf, Port Blair Harbour, A&N Islands PM10 : The minimum and maximum PM10 values monitored in the Study Area was 10 ug/m3 and 65 ug/m3 with the mean value of 38.8 ug/m3 against the NAAQ Norm value of 100 ug/m3. 3 3 SO2 : The minimum and maximum values monitored in the Study Area was 6 ug/m and 18 ug/m with the mean value of 11.5 ug/m3 against the NAAQ limit value of 80 ug/m3 during the study period. NOx : The minimum and maximum values monitored in the Study Area was 6 ug/m3 and 24 ug/m3 with the mean value of 13.9 ug/m3 against the NAAQ limit value of 80 ug/m3 during the study period. 3 Ammonia (NH3) concentrations were monitored <5 mg/m at all the monitoring locations against the NAAQ limit value of 400 ug/m3. 3 3 O3 : The minimum and maximum values monitored in the Study Area was <2 ug/m and 4.1 ug/m during the study period against the NAAQ limit value of 100 ug/m3. CO : The minimum and maximum values monitored in the Study Area was <114.5 ug/m3 and 458 ug/m3 during the study period against the NAAQ limit value of 2,000 ug/m3. Particulate Lead (Pb) concentrations were monitored <0.05 ug/m3 at all the monitoring locations against the NAAQ limit value of 1.0 ug/m3. Arsenic (As) concentrations were monitored <0.2 ng/m3 at all the monitoring locations against the NAAQ limit value of 6 ng/m3 (annual mean).
