EXECUTIVE SUMMARY

1. INTRODUCTION M/s Delhi International Airport Limited proposes for development of Commercial building at LP-1B-03 at Gateway District of Aerocity, IGI Airport, New Delhi. The project has issued TOR from EAC, MoEF&CC dated 30.11.2018 however, due to some change in areas, the project has taken amendment in TOR from EAC, MoEF&CC dated 07.03.2019. the report is prepared on the basis of ToR Granted. The project falls under Item 8(b) with built up area more than 1,50,000sq m (Township and Area Development projects) of the Environmental Impact Assessment (EIA) Notification dated September 14, 2006. This report includes the Identification and Prediction of significant environmental impacts due to the proposed project along with an appropriate Environmental Management Plan both for the construction phase and for its operation and maintenance later on the basis of the Environmental Impact Assessment (EIA) Notification dated September 14, 2006.

2. NEED OF EIA STUDY Rapid industrialization and population explosion in India has led to the migration of peoples from villages to cities which increase human settlement in world’s growing cities and towns. This generates several issues with regard to the environment. In order to study either its beneficial or harmful effect; evaluation of any project through EIA has become a must. Undertaking EIA for construction industry and improving site management can reduce environmental impacts both on and off site. The EIA study is necessary to prepare a detailed account of environmental impact of the proposed activity so that appropriate interventions could be taken. Ministry of Environment and Forests, the controlling authority has issued mandatory requirements for regulation. A Gazette Notification on Environmental Impact Assessment (Amendment) was issued on 14th September, 2006. This defines “Requirements and procedures for seeking environmental clearance of projects” vis-à-vis a list of activities requiring prior Environmental Clearance. Accordingly, the proposed project falls under the category for which EIA study is essential. This project has been designed as per EIA Notification from the Ministry of Environment and Forests (MoEF&CC) under its recent notification, applicable local bylaws and others Rules and regulations. The Executive Summary summarizes the findings of the EIA study undertaken in accordance with the TOR issued by concern Authority and EIA guidelines. The summary is intended to provide and overview of prevailing baseline conditions, key environmental issues and their likely impacts and also list the major recommended mitigation measures to attenuate the impacts

3.6 Geology The area is characterized by unconsolidated quaternary alluvial deposits belonging to middle to late Pleistocene age. The area comprises of silt and clay mixed with kankar in varying proportions. Only 18 sq km area is covered by denudational hills especially in the eastern part of the district. Geological cross sections along Kair–Nicholson range and along Kair–Dwarka–R.K.Puram.

3.6.1 Geomorphology Major part of the district is under yamuna alluvial plain and small part of the district has quartzites on the eastern border of the district. 3.6.2 Drainage The major drainage of the district is Najafgarh drain. Najafgarh drain originates from NajafgarhJheel on Delhi-Haryana border and meets the river yamuna. 3.6.3 Hydrogeology The hydrogeological studies to understand the local geology, geomorphic features, drainage network, aquifer characteristics and yield of water. Accordingly, various components are controlling the hydrogeological regime. • Occurrence of Ground Water Ground water systems are a result of the complex combination of different lithological and structural types within an area that together constitute an aquifer within which ground water accumulates and moves. Rather than describing individual lithologies and their tendencies to form aquifers or otherwise, it is useful to describe the ground water as one continuous across various lithological types (Kulkarni and Deolankar, 1995). Thick pile of alluvium overlies the basement rock and consists of alternate layers of silt, clay, sand and kankar. Nearly fine to medium sand and silt grade sediments occur frequently up to the depth of 50 m along with buff coloured clayey bed admixed with coarse kankars. On the other hand, after the depth of 50 m, thickness of silty–clay and clay (Light yellow) beds with kankars increases with depth. The semi-plastic and plastic clay beds are also common at deeper depth i.e. 80 to 250 m bgl. The granular zone at deeper depth is not as frequent as in the shallower depth. The bed rock has been encountered at many places i.e. in Dhansa (297 m), Pindwalakala (300 m), Toghanpur (298 m) and Jhuljhli (251 m). • Depth to Water Level (Source: CGWB report, NCT Delhi) Depth to water level of the district shows large variation. Shallow water level is observed in the south western part of the district while deeper water levels are observed in the eastern part of the district. The depth to water level during pre- monsoon period (May-2012) in the district ranges from 2.40 to 53.17 m bgl and during post monsoon period (November-2012), it varies from 0.69 to 54.02 m bgl.





• Seasonal Water Level Fluctuation The seasonal water level fluctuation has been computed from the water level data obtained from the ground water observation wells monitored in the area during pre-monsoon and post-monsoon periods. Fluctuation in water level is the outcome of mainly the amount of rainfall received by the area and ground water withdrawal taken from the ground water reservoir. The seasonal fluctuation in water level between pre and post monsoon shows rise in water level ranging from 0.25 to 7.18 m and fall ranging from 0.05 to 1.27 m. • Long Term Water Level Trend The long-term water level trend analysis in the district over the last 10 years period shows a fall of 0.30 to 6.90 m during the pre-monsoon period and a fall of 0.07 to 6.08 m in during the post-monsoon period. • Depth to Water Level (Ground Water Year Book 2015-16 NCT Delhi) The depth to water level recorded in NCT Delhi during May 2015 ranges from 1.20 to 62.22 meter below ground level (m bgl). About 50% wells of South district show more than 40 m bgl water level and 19% wells have 20 to 40 m bgl water level. In New Delhi and Southwest districts, water level in the range of 10 to 20 m bgl is shown by 57% and 35% wells respectively. In North, East and Northwest districts, 29%, 40% and 46% wells show water levels in the range of 5 to10 m bgl respectively. In East, North, Northeast, Northwest, and West districts 30%, 57%, 50%, 29% and 12% of wells show water level in the range of 2 to 5 m bgl respectively. The entire Yamuna flood plain is also falling in the 2 to 5 m bgl category. The depth to water level recorded in NCT Delhi during November 2015 ranges from 0.72 to 61.13 m bgl. About 50% wells of South district shown more than 40 m bgl water level and in 12% of the wells the water level varies between 20 to 40 m bgl. In Southwest district 35% and 38% wells show fall in the water level category of 10 to 20 and 20 to 40 m bgl respectively. The depth to water level of East, Northeast, Northwest and West districts show 40%, 25%, 34% and 33% in the range of 5 to 10 m bgl whereas in East, North, Northeast, Northwest and West districts the water levels are in the range of 2 to 5 m bgl in 30%, 57%, 25%, 24% and 22% respectively. In the entire Yamuna flood plain the water level are falling between 2 to 5 m bgl during this period.

3.7 SOIL QUALITY 3.7.1 Soil characteristics

Physical Characteristics The textural class of soil sample is sandy. Bulk density values confirm the textural class. Bulk density, besides being an interesting and significant physical characteristic, is very important as a basis for certain computations. The bulk density of the soil sample under consideration is 1.40 gm/cc, and confirms the moderately fine texture of the soils of the area under study.

Chemical Characteristics The pH of available soil is 7.82 indicating soils are slightly alkaline and the EC is 477µs/cm, below the limits to be called as saline and hence the soils are normal. The available nitrogen in 52.1 mg/kg showing very low to good nitrogen content and the phosphorus is 7.5 mg/kg and falls under good to more than sufficient category. The potassium content is 45 kg/ha and is very more than sufficient. The calcium content of sample is 2174 mg/kg, and exchangeable cation is 13.2. The magnesium content is 214 mg/kg, which is further adding to base saturation.





Inference: The Sodium & Chloride content in soil are not so high in range. Most plants accumulate both sodium (Na+) and chloride (Cl–) ions to high concentration in their shoot tissues when grown in saline soils and lead to retarded growth patterns. To treat high salinity frequent irrigation and use of gypsum is suggested, however, in this project, salinity of soil is not so high.

3.8 AIR ENVIRONMENT The prime objective of the baseline air quality study is to assess the existing air quality of the area. This will also be useful for assessing the conformity to standards of the ambient air quality during the project operations. This section describes the selection of sampling locations, methodology adopted for sampling, analytical techniques and frequency of sampling. The ambient air quality was monitored at six locations in and around the existing airport. The air quality monitoring was conducted as per revised NAAQS 2009.

Methodology adopted for Air Quality Survey

The baseline status of the ambient air quality has been assessed through a scientifically designed ambient air quality-monitoring network. The design of monitoring network in the air quality surveillance program has been based on the following considerations:

Meteorological conditions on synoptic scale; The methodology for conducting the baseline environmental survey and selection of sampling locations considered the guidelines given in the EIA manual of the MoEF&CC&CC; Topography of the study area; Representatives of regional background air quality for obtaining baseline status; and Representatives of likely impact areas. The existing conditions within the study area is highly characterized by urban commercial activities, traffic and industrial activities. These are observed in addition to the existing airport operations. 3.8.1 Meteorological Data from Secondary Sources Meteorological conditions prevailing at a geographical area play an important role in determining its existing air quality and environmental conditions. Climate, seasons and other meteorological parameters influence and alter site-specific activities and operations. The meteorological data collected from secondary sources for the area are presented in the subsequent sections. 3.8.2 Temperature Climatological data is used for devising baseline ambient air quality monitoring plans. Table 3.8 & Table 3.9 presents the minimum and maximum temperature profile of the





region (data collected at MET Station Palam, New Delhi) for the period 1997 to 2011 from Indian Meteorological Department (IMD), Lodhi Road, New Delhi. As per the data given in Table 3.7 and Table 3.8, the study area experienced averaged extreme lowest temperature 5.9o C in the month of December, 2005 and extreme highest 42.6o Cin the month of June, 2009 respectively.

Over the course of a year, wind usually blows in all directions with varying frequencies. Certain directions, which occur more frequently than others, are known as the prevailing wind directions. Pollutant concentrations typically decrease with increasing wind speed as a result of dispersion. However, when wind speeds are high, while there is good dispersion of gases and particles, there is more potential for re-suspending surface dusts. Wind speed near zero, indicating low turbulence and may lead to very high pollutant concentrations near the ground. Wind speed increases with height as surface friction reduces. Ground level pollutant concentration is inversely proportional to the wind speed. Hence, during the higher wind speed month, the ground level pollutant concentration would be less and vice.





The wind data has been obtained from nearest IMD station for the period 1993-2002. The Analysis of wind records during 1993 – 2002 shows that the winds are generally light to moderate in this area. It can be seen that the annual mean wind speed varies from 3.9 to 9.4 Km/h. The strongest winds are observed during the months of May – June i.e. Summer Season and the weakest during October – November. The monthly mean values of the various meteorological parameters for the period 1993-2002 and Yearwise monthly mean value from year 2000 to 2005 are presented in Table 3.12 Table-3.12: Monthly Mean Wind Speed in KMPH (Year 1993 – 2005)

The amount of turbulence can be categorized into defined increments or "stability classes". The most commonly used categories are the Pasquill stability classes A, B, C, D, E, and F. Class A denotes the most unstable or most turbulent conditions and Class F denotes the most stable or least turbulent conditions. The frequency of stability classes during the monitoring period is provided in Table 3.14. TABLE-3.14: FREQUENCY OF STABILITY CLASSES

Stability Class Frequency (%)






A – Extremely Unstable 18.6

B – Unstable 16.3

C – Slightly Unstable 5.8

D – Neutral 6.5

E – Slightly Stable 12.1

F – Stable to Extremely Stable 40.7

The data indicate that during the monitoring period, the site exhibited trends of primarily stable to extremely stable conditions. Stable conditions exhibit poor vertical mixing, and low levels of contaminant dispersion. Use of this stability data for modeling purposes will produce higher concentrations of pollutants at a given receptor (i.e. more conservative results). 3.8.8 Mixing height Mixing Height (MH) is the vertical extent through which the contaminant plume can be mixed. Forecasting of mixing height is done with the aid of the vertical temperature profile. The MH is a function of stability. In unstable air, the MH is higher and in stable air the MH is lower. With a lower MH, there is a smaller volume of air in which the pollutant can be dispersed, resulting in higher concentrations in the ambient environment. There is a seasonal variation of MH. During summer daylight hours, MH can be few thousand feet whereas for winter it can be a few hundred feet. It varies also in the course of a day. It is lowest at night and increases during the day. Secondary information has been used to determine the mixing height over Delhi district and it varies from 50-2500 meters (CPCB, 2002). 3.8.9 Averaged Meteorological Data The meteorology of the area plays an important role in the air quality surveillance programmes. The micrometeorological parameters regulate the transport and diffusion of pollutants into the atmosphere. The Meteorological study has been carried at the project site for one season i.e. Dec 2018 to Feb 2019. The measurements of wind speed and direction, temperature, humidity and rainfall are important parameters used in the study of air quality monitoring results and to further understand the chemical reactions that occur in the atmosphere. Meteorological monitoring is used to predict air pollution events such as inversions, high pollutant concentration days. 3.8.10 Windrose Wind speed and wind direction data recorded during the study period (Dec 2018 to Feb 2019) is useful in identifying the influence of meteorology on the air quality of the area. Based on the collected meteorological data, relative percentage frequencies of different wind directions are calculated and plotted as wind roses of eight directions viz., N, NE, E, SE, S, SW, W and NW for eight hourly and twenty four hour duration respectively. Maximum and minimum temperatures including percentage relative humidity were recorded simultaneously. A windrose has been plotted for average of 24 hours for 3 successive months that shows the predominant wind direction and has been presented in Figure-3.10.

Wind direction is NW to SE and Wind speed was in the range of 3.6- 5.7 m/s.

During the construction and operation phase of proposed project, air pollution causing agents can be vehicular movement and occasional use of DG sets. Stacks for DG sets will be provided with proper height as per CPCB Guidelines and emissions from DG sets will meet the DG emission standards.

3.9 AMBIENT AIR QUALITY The prime objective of collecting baseline air quality data is to assess the ambient air quality of the project influenced area. Ambient air quality monitoring locations were selected based on the representation of population, material and ecosystem exposure monitoring for the pollutants emitted from the project and the compliance monitoring for compliance of National Ambient Air Quality Monitoring Standards. The baseline study of air quality within the project-influenced area of 10 km has been carried out by selecting the monitoring locations based on the following criteria:

Meteorological condition on a synoptic scale

Topography of the project influenced area

Representation of the regional background levels

Representation of the site

Influence of the existing sources

Major human settlement in the project influenced area

3.9.1 Ambient Air Quality Monitoring Ambient air quality monitoring (24 hrs –average result for monitoring period) has been carried out during one season i.e. December-2018 to February-2019 at six locations.The parameters for air quality were selected as per the stipulated National Ambient Air Quality standards, MoEF&CC&CC and these were Particulate Matter less than 2.5 µg/m3

(PM2.5), Particulate Matter less than 10 µg/m3 (PM10), Sulphur Dioxide (SO2), Oxides of Nitrogen (NOx) and Carbon Monoxide (CO) etc. were monitored and average results are as tabulated in Table-3.15.

3.9.2 Observations

It is observed that PM 10 and PM 2.5 exceed at all monitored locations and its continuous exposure to human being can have health impacts. Further impacts will be on nearby biodiversity where deposition of larger particle PM 10 and PM2.5 will result in retarded growth due to reduced photosynthesis. All other parameters like SO2, NO2 and CO were found well within the NAAQS limits as specified by CPCB. Inference: PM 10 and PM 2.5 parameters of ambient air quality is higher in the entire region due to non-anthropogenic reasons like dust borne wind and due to anthropogenic reasons like some construction related activity and vehicle movement in





the region.

3.10 Water Environment Water environment consists of water resources such as ground water, ponds, streams, rivers etc. Water quality assessment is one of the essential components of EIA study. Such assessment helps in evaluating the existing health of water body and suggesting appropriate mitigation measures to minimize the potential impact from development projects. Water quality of ground water has been studied in order to assess proposed water- drinking, and horticulture purpose. During the survey samples of water within the periphery of 10 km. radius were analyzed. 3.10.1 Water Quality Monitoring In order to assess the existing water quality, ground water sample was collected from near byproject site and analyzed as per standard methods for examination of water and wastewater published by American Public Health Association/ American Water Works Association and the Bureau of Indian Standards (APHA/ AWWA & BIS) and compared with permitted desirable standards set by BIS (IS 10500: 1991). The surface and ground water monitoring locations have been shown in Table-3.17. The important ground & surface water parameters were analyzed for one season i.e. Dec-2018 to Feb-2019 and the average results are produced in Table-3.18 A, Table-3.18 B Table-3.17: Water Quality Monitoring Location

3.10.3 Observations (Ground water) Result show that metals such as Copper, Lead, Zinc, Arsenic, Mercury are well within both Acceptable and Permissible limit, similarly pH, Phenolic compound are well within





limit as per BIS Specification IS 10500-2012. Total Hardness, Alkalinity and Total Dissolved Solid are found beyond Acceptable limit but found within permissible limit. Inference: Though permissible limit is 2000 for TDS but for human consumption should not exceed 500 mg/lt. Such exceedance in the range 1100 and more are bound to have deteriorating health impacts. Fluoride is also in the higher range which may primarily produces effects on skeletal tissues (bones and teeth). Also this quality of water will impact soil quality and retarded vegetation growth. Delhi region is restricted for extraction of ground water; hence ground water will not be extracted for any use.

3.11 Noise Environment The noise level prevailing at a particular location in the outdoor environment is contributed by all kinds of sources at various distances around that location. Continuous, temporal and spatial variations occur in ambient noise levels depending on the type of surrounding activities. The impact of noise on the health of individual depends on physical dose of noise viz. noise level, frequency, intermittency etc. and human factors viz. sex, age, health status, type of activity, occupational exposure etc. The intensity also depends on psychological and physiological state of individuals. The impact due to noise does undergo seasonal variations except some directional changes depending upon the predominant wind direction. Noise levels have been measured for Six locations. The baseline study of noise levels in the study area of 10 km has been carried out by selecting the noise monitoring locations based on the following criteria:

Source of noise

Proximity of the noise generating source to the human settlements

Exposure time

Source: http://www.epa.nsw.gov.au/soe/97/ch1/15_3.htm 3.11.1 Noise Quality Unwanted noise and unpleasant sounds are generally classified as noise pollution. Normally a person begins to identify sounds when a level of 10 to 15 dB is reached. The other end of the scale is known as the threshold of pain (140 dB), or the point at which the average person experiences pain. Noise is generally measured in frequency-weighted scales and noise quality measurements are generally represent in the ‘A’ level and reported as dB (A). Methodology of Background Noise Quality Monitoring A site–specific background noise quality monitoring program was conducted for the existing project site. The basic considerations for designing noise quality surveillance programme include:

Vehicle Movement Within the Impact Zone

Activities in surrounding villages / settlements/nearby areas

Ecologically Sensitive Locations Based on the above mentioned criteria, noise monitoring was conducted at 6 locations within the impact zone. Sound Pressure Level (SPL) measurements were automatically recorded to give the noise level for every hour, continuously for 24 hours in a day. Accordingly one full day (i.e. 24 hourly values) of data was collected at each of the locations. The standards of equivalent noise levels viz. Leq-day and Leq-night, have been prescribed by the CPCB as given in Table-3.22. Table-3.21: Ambient Noise Standards as per CPCB

Where Li = levels observed at n equally spaced times during interval T. Sources of Noise Emissions Surrounding the Site The major source of noise in the site surrounding area is the vehicular movement along Southern peripheral road and construction activities in the vicinity of the site. The impacts from these sources are expected to be captured in the levels of noise measured in the site-specific background noise monitoring study. Noise Level in the Project Influence Area The hourly noise levels were recorded for one season i.e. Dec-2018 to Feb-2019. Baseline monitoring of noise was carried out at Six selected monitoring locations for 24 hours considering. The monitoring average results have been summarized in the Table-3.22.

The vast array of interactions among the various components of biodiversity makes the planet habitable for all Species, including humans. There is a growing recognition that, biological diversity is a global asset of tremendous value to present and future generations. At the same time, the threat to species and ecosystems has never been as great as it is today. Species extinction caused by human activities continues at an alarming rate. Protecting biodiversity is in our self-interest. The biological study was under taken by Ecology & Biodiversity Expert, as a part of the EIA study report to understand the present status of ecosystem prevailing in the study area, to compare it with past condition with the help of available data, to predict changes in the

As per secondary source such as few literatures and news clippings, some species observed in buffer zone were of common occurrence are Black Kite and Black Winget Kite and Peaflow which are listed in Schedule-I species as per WPA 1972. 3.12.3 Conservation Plan for peacock An Indian Peafowl or Peacock (Pavo Cristatus) is a large pheasant justifiably declared as the National Bird of India in 1963 due to its flagship value founded on its glorious position in mythology and its widespread distribution and grandeur. In India, it is given the utmost protection by inclusion in Schedule I of Indian Wildlife Act, 1972 (2002). Being a wide spread species, apart from the various urban habitats, it is also found in agriculture field, along stream with good vegetation and close to human habitation in semi – feral conditions. In the present study area this species have been confirmed from various habitats located near the project periphery. Since the buffer zone of the proposed project reported with Schedule 1 Species named as Pavo cristatus commonly known as peacock, a systematic study was conducted to assess their status in terms of movement and habitat use of the species. At first, a detailed biological survey of the core & buffer zone was carried out to understand the status distribution of the species in the study area. Habitat improvement program will include plantation of various plant species like Bassia latifolia (Mahua), Mangifera Indica (Ambo), Lagerstroemia parviflora (Seja), Tamarindus Indica (Ambli) and other species reported from the study area should be taken into priority. In order to improve vegetation cover, it is suggested to carry out extensive afforestation program in different phases. These species will help to provide habitat for faunal diversity, and also increases the species diversity and maintain the naturalness of the surrounding area. Presented survey of the peacock in the buffer zone of the project site shows that, peafowl is well adapted to the existing rural setting of the study area. However, the following points can give an insight on the overall status of peafowl in the study area and thereby plan for better management strategies related to proposed activities.

Local resident of the study area well aware of the movement pattern of peafowl in their surrounding habitats.

Peafowl uses agriculture and various rural habitats as a feeding ground during day time while during night time they take shelter on the trees as well as on the roof of the houses. It clearly indicates peafowl normally uses ecosystem or habitats adjacent to village. From the above said facts, it can be inferred that, some villages of the buffer zone provide roosting and feeding ground for peafowl, while core zone do not have potential habitat for roosting or feeding ground for peafowl. Therefore, it has been visualized that, the proposed project will not have any significant impact on peacock in terms of their normal movements and other activities. However, it is necessity to take some management option like habitat improvement in the villages located in the immediate vicinity of the project site. So, habitat improvement programme (Plantation of recommended and local plant species) will be under taken in (in consultation of forest department) different villages located in the close





vicinity of the project area. Under this programme sampling will be distributed in the nearby villages with the consultation of the local forest department. 3.13 Socio Economic Environment

4.0 ANTICIPATED ENVIRONMENTAL IMPACTS & MITIGATION MEASURES

This chapter discusses identification and appraisal of various environmental impacts due to the proposed project. Generally, the environmental impacts can be categorized as either primary or secondary. The development, construction and functional phase of the proposed project comprise various activities, each of which may have some impact on environmental parameters. Various impacts during the development & construction and operation phase on the environmental parameters have been studied to estimate the impact on environment. In development phase, basic infrastructure facilities like internal roads, rainwater harvesting, storm water drainage, street lighting etc. will be developed. Major part of project will be sold in the form of Flats. For proper evaluation and assessment of the environmental impacts due to development and construction and functional phase of proposed project, understanding to the various activities associated with the proposed project is essential. Various activities related to the project would be different, in terms of nature during the development, construction and functional phase. The impact identification and prediction process aims to:

Identify potential source or cause of impact throughout the life of project.

Characterize the potential impacts affecting a target or receptor (physical, human and socioeconomic).

Assess the potential of changing the likely-hood of impact through Environmental Management Plan (EMP)

Prediction of the impacts due to the development, construction and functional activities encompass the development process to be undertaken during construction and functional phases. For each category of environmental receptor (such as, ambient air quality, water quality, soils, land, etc) the potential impacts of activities during development, construction and functional phases and magnitude of the impacts have been assessed and discussed in detail in following sub sections. In each case, cognizance has been taken to mitigation measures inherited in the development, construction and functional phase. 4.1 Pollution Sources Pollutants generated during the construction and operation phase of the proposed development either be liquid, solid and gaseous in nature. The generation of pollution may be periodic, continuous or accidental.

4.3 Impacts Due to Project Location

4.3.1 Displacement of People

Since, the project and its associated activities are limited to acquired and approved area of 32189 sq m and is free from encroachment, and ready for development of project in all respect, hence no displacement of any person is anticipated. Hence there is no rehabilitation and resettlement related issues are involved. The site falls under commercial use. No portion of the site comes under forest/ reserve forest or agricultural land.





4.3.2 Change of Land use The development in the entire project influenced area is as per the local development plan of DDA, hence there will be no change in designated land use. Land use change from barren land to Commercial purpose is directly associated with positive developments in human use environment and may be considered as a positive impact. The plot of project will be developed as per the local building by-laws.

4.3.3 Landscaping and Shelterbelt Development The proposed site is earmarked for development of commercialcomplex. The site has no trees. Under landscaping and tree plantation3220sqmof Plot Areahas been provided for development of green area.

4.3.4 Shifting of Utilities The proposed site is a vacant land proposed for development of commercial complex project; there shall not be any shifting of existing utilities such as water supply pipelines, sewers, electrical lines, etc. due to the proposed project.

4.3.5 Impact on Archaeological Property There are no anthropological or archaeological sites or artefacts located near the project site. Since all the activities related to project during construction or operational stage shall be confined to the designated site, and the nature and magnitude of the activities is envisaged to be temporary and insignificant, hence no major or long term impact to any archaeological property is anticipated.

4.4 Impact Due To Project Construction

4.4.1 Pressure on Local Infrastructure During the construction stage, demand for basic amenities, such as water, power etc., for the construction labour will take place. Thus, the proposed project is supposed to have beneficial impacts along with the requirement of construction activities, put pressure on the existing infrastructure. Considering the nature of the project, impact shall be short term and low in magnitude and are limited to construction phase only.

4.4.2 Impact on Soil During construction phase there shall be import of material from outside specially the construction material like bricks, cement, murrum, lining material, insulation bricks, HDPE pipes, backfill material, sand, clay, etc, which may change the characteristic of the soil in the construction area. In addition to that, municipal wastes due to construction workers, domestic sewage & sullage from construction labour canteen and office at project site etc, may contribute to changing the soil characteristics. Environment





management plan will be adopted to mitigate the soil contaminations. Quantities of earthwork involved in cutting, filling, etc. The soil will be collected separately and preserved in stacks with side slopes not exceeding 1:5. The topsoil (soil on the top 20 cm depth) will be collected & preserved separately in a stack covered by tarpaulin. Efforts will be made to reinstate the soil for backfilling purposes. Topsoil will be reused for horticultural areas. The spillage of oil from the machinery or cement residue from concrete mixer plants might contaminate the soil if not properly collected and disposed off. Thus most stringent safety and construction management norm will be implemented at site. The dripping of oil from construction vehicles might cause soil contamination. In order to prevent soil contamination likely to result from the oil spill and dripping from vehicles, drip pans shall be placed at the parking places of vehicles and the dripped oil shall be collected and subsequently sent to the authorized recycling agencies. Hazardous waste shall be managed as per Manufacture, Storage and Import of Hazardous Chemical Rules (MSHIC) and Hazardous Wastes Storage, Handling and Transportation Rules of MoEF&CC&CC.

Mitigation Measures

• No loose soil will be allowed to store at site to avoid runoff during rains. Proper compaction and stabilization will be ensured during filling and levelling.

• Hazardous waste such as used oil of DG sets shall be collected and stored in leak proof containers and kept in isolated place and will be given to authorised recyclers of CPCB.

• Colour coded dust bins will be placed at construction site so that segregation of waste shall be done at source.

• All recycled material such as metal, paper, plastic wastes, shall be given to authorised recycler and construction waste (if any) shall be utilised with the site for levelling/ backfilling.

4.4.3 Impact on Water Quality

Following are the most susceptible locations for contamination of water during construction:

Waterlogged areas during the period of construction and erosion - Landfill material may increase the turbidity of the water logged area and thereby may invite vector of disease.

Ground water resources close to construction material storage yard, concrete mixer plants and maintenance sites of construction vehicles; and Leakage of lubricant or spill may cause water pollution of surface and ground water body. No bore-well exists within the site and within the vicinity of project site no designated perennial water body are present. Since all construction related activities will be confined to the enclosed construction area, no major impacts on the water bodies present in project influenced area are anticipated. Whatever impact due to accidental





spills or due to bad construction practice, will be short term and low in magnitude and confined to the construction period only.

Construction & development of site Development of the proposed site could lead to stockpiling and excavation activity on site, thereby causing erosion of base soil. The runoff from the site may contain high quantity of suspended solids (SS). The impact of runoff may not be very significant except during rainy season. Further construction of garland drains will reduce the runoff from the stockpiles. Bored piling may be carried out for building structures. Bore piling, if used, requires the use of chemical lubricants, which generates a wastewater stream requiring treatment before discharge. Site workshop The repair and maintenance of equipments/ vehicles on site would generate waste containing oil and grease. The wastewater stream would also be generated from vehicle washing. The impact can be mitigated to a great extent by installing oil and grease traps during construction phase. Construction of roads & parking areas The impact from the road construction depends on both the construction practices and the type of material used. Construction waste of electrical installation, DG sets, painting and flooring is likely to create significant impact. This type of waste would be stock piled and disposed properly. Labour Colony During construction phase, wastewater shall be generated from labour colony. High levels of BOD, SS, Nitrogen and E. Coli would characterize wastewater generated. Significant water quality impact will occur. The sewage generated from mobile toilets will be treated in mobile STP and treated water will be used for sprinkling on roads for dust suppression.

Mitigation Measures

Following measures to be taken for water quality during construction phase: Appropriate sanitation facilities to be provided for the construction workers to reduce

impact on surface water quality. Entire waste water will be treated and reused for landscaping & horticulture, flushing,

HVAC activities and construction sites, where ever possible.

Control of spillage of fuel oil and storage of oil barrels on cemented floor. Waste oil generated during maintenance of construction equipment will be collected

and disposed to approved waste oil recyclers for recycling and reuse. Runoff from fueling area, vehicle parking areas, etc. will be passed through oil

interceptor.





A sediment trap will be provided to prevent the discharge of excessive suspended solids Municipal and other wastes generated at the proposed project will be collected and

disposed suitability as per standards practices and regulatory requirement. Rain Water Harvesting (RWH) pits shall be provided to recharge the ground water. Suitable drainage network would be made to ensure proper draining of wastewater

from the construction sites, so that such water do not form stagnant pools nor aggravate soil erosion.

4.4.4 Impact on Air Quality

Potential impacts on the air quality during the construction stage will be due to the fugitive dust and the exhaust gases generated in and around the construction site due to DG set operation, vehicular movement, earthworks, foundation, drilling, grading and other construction related activities. Dust is major component of air pollution, generated mainly from the following construction activities:

Site clearance and use of heavy vehicles and machinery / equipment etc. at construction site;

Storage & Handling of construction materials such as sand, cement, etc. at the construction site;

Mitigation Measures It is a better way to plant more trees to avoid air pollution along with proper maintenance of vehicles, DG sets, sprinkling of water on construction areas. In addition of this, following measures shall be adopted:

Batching plant shall be covered to avoid dust.

Regular sprinkling of water on construction site to suppress dust emissions.

Adequate stack height shall be provided with the DG set for natural dispersion of pollutants.

Only PUC holding vehicles are allowed to the project site to check proper maintenance to avoid air pollution.

No use of asbestos.

4.4.5 Impact on Noise Quality

Noise is perceived as one of the most undesirable consequences of construction activity. Though the level of discomfort caused by noise is subjective, the most commonly reported impacts of increased noise levels are interference in verbal communication and disturbance in sleep. Due to the various construction activities, there will be short-term adverse noise impacts in the immediate vicinity of the project corridor. The construction activities include:





Operation of DG sets, concreting and mixing Excavation for foundations with excavator (if used); Construction plant and heavy vehicle movement. Piling and hammering activities

The areas affected are those close to the project site. At the peak of construction, marginal increase in the noise level is expected to occur. Table-4.3: Typical Noise Levels from Construction Equipment

Description Typical Noise Level Range , dB (A)

Reference Distance, m

Front loaders 72-84 1.0

Backhoes 72-93 1.0

Tractors 76-96 1.0

Scrapers, Graders 80-93 1.0

Pavers 86-88 1.0

Trucks (>1200 cc) 82-94 1.0

Concrete mixers 75-88 1.0

Crane (moveable) 75-86 1.0

Crane (derrick) 86-88 1.0

Pumps 69-71 1.0

Compressors 74-86 1.0

Overall, the impact of noise on the environment will be insignificant, reversible and mainly confined to the day hours. Noisy construction activities will be carried during the day time only and this will effectively reduce the night time ambient noise level. As per best practice all the noise generating activities shall be undertaken during day hours and enclosure shall be provided wherever applicable to further minimize noise pollution. These impacts will be short term during construction phase, with provision of proper enclosures for high noise generation sources and use of proper personal protective devices i.e. ear plug and ear muff will marginalize the impact. Mathematical modeling is carried out for DG sets. These DG sets are assumed to be operating for four hours in day during peak loads i.e. two hours in morning and two hours in evening.

Mitigation Measures

• Ear plugs and Ear muffs shall be provided to the workers at construction site • All the construction sites will be provided with barricades; • Big foliage trees shall be planted around the periphery of the construction site. • Provision of silencers at the exit of noise source on the machinery;





• Vehicles shall be properly maintained and serviced. • Regular maintenance of construction equipment; • Inlet and outlet mufflers will be provided which are easy to design; and

4.4.6 Socio-economic Impacts

The social impacts during the construction stage could result due to influx of some migrant workers and associated induced development etc. This will ensure a rise in the consumption of consumer goods in the local area, which will tend to boost up the local economy. As local labours will be hired from the villages in vicinity of the project site, initial conflict is not envisaged. As far as possible local labour within the project influenced area shall be utilized for the construction purpose and all the activities related to construction worker shall be confined to the project site only, hence no adverse social impacts are envisaged due to the proposed project. Children below 14 will not be appointed for construction.

4.5 Impacts Due To Project Operation During the Operation phase, there might be impacts on the air, water and land environment and socio-economic aspects. The subsequent sections present the adverse, beneficial, short term and long term impacts due to the operation of the proposed project.

4.5.1 Air Environment Air pollution can cause significant effects on the ambient environment, and subsequently on humans, animals, vegetation and materials. It primarily affects the respiratory (e.g. by fine dust), circulatory (e.g. by carbon monoxide) and olfactory (e.g. by odors) systems in humans. In most cases, air pollution aggravates pre-existing diseases or degrades health status, making people more susceptible to other infections or the development of chronic respiratory and cardiovascular diseases. Environmental impacts from air pollution can include acidic deposition and reduction in visibility. Assessment of prevailing ambient air quality status in the vicinity of proposed project site is an important part of environmental impact assessment study. The tropical climatic conditions, especially winds prevailing in India mainly control the dispersion of air pollutants during different seasons. According to the Indian climatology, for all practical purposes in air pollution studies, there are three seasons in a year, viz. winter, pre-monsoon and post-monsoon. For the quantitative assessment of the environmental impact on the ambient air environment during these seasons, atmospheric dispersion modelling is required.





Atmospheric dispersion modelling is the mathematical simulation of how air pollutants disperse in the ambient atmosphere. It is performed with computer programs that solve the mathematical equations and algorithms which simulate the pollutant dispersion. The dispersion models are used to estimate or to predict the concentration of air pollutants emitted from sources on the desired area. Such models are important to governmental agencies tasked with protecting and managing the ambient air quality. The models are typically employed to determine whether the ambient air quality level due to proposed project will compliance with the National Ambient Air Quality Standards (NAAQS) or not. Over and above models also serve to assist in the design of effective control strategies to reduce emissions of harmful air pollutants. Methodology For the proposed atmospheric dispersion modelling study, United States Environmental Protection Agency (USEPA) approved and also recommended by the Ministry of Environment and Forests (MoEF&CC&CC), Government of India, regulatory air quality model Airmode is applied to predict ground level incremental concentrations (GLCs) of concerned critical pollutants. Prior to air quality modelling exercise, meteorological condition during one season over project site is extensively studied. Concentrations are estimated for the critical pollutants assessed over appropriate averaging times (i.e. 8 hours and 24 hours) based on the applicability of the National Ambient Air Quality Standards (NAAQS). Meteorology Meteorology is the fluid mechanics applied to the atmosphere. Meteorological conditions play an important role in determining existing air quality and environmental conditions. The essential relationship between meteorology and atmospheric dispersion involves the wind in the broadest sense of the term. Wind fluctuations over a very wide range of time and space scales accomplish dispersion and strongly influence other processes associated with them. The characterization of the existing meteorological conditions near a source of pollutants is, therefore, a critical aspect for assessing air quality in the ambient environment. For the rapid air quality impact assessment meteorological data for the desired season/period over the project region are used for air quality modelling. The following subsections describe the prime meteorological parameters during the observation period which govern the dispersion of pollutants. Atmospheric stability A measure of the tendency of air to move upward or downward within the atmosphere generates turbulence. The atmosphere may be more or less turbulent at any given time, depending on the amount of incoming solar radiation as well as other factors. There are six defined Pasquill atmospheric stability classes, from A to F, each representing a different degree of turbulence in the atmosphere. When moderate to strong incoming solar radiation heats air near the ground, causing it to rise and generating large eddies, the atmosphere is considered unstable. Unstable conditions are associated with atmospheric stability classes A, B and C. In this stability class air has strong tendency to move up or down, and the atmosphere is more turbulent. When solar radiation is relatively weak or absent, air near the surface has reduced tendency to rise and less turbulence develops. In





this case, the atmosphere is considered stable, the wind is weak, and the stability class would be E or F. Stability classes D represents conditions of neutral stability (moderately turbulent). Neutral conditions are associated with relatively strong wind speeds and moderate solar radiation. The frequency of stability classes during the study period is provided in Table-4.4. Table-4.4: Frequency of Stability Classes

Stability Class Frequency (%)

A – Extremely Unstable 5.5

B – Unstable 23.6

C – Slightly Unstable 12.9

D – Neutral 9.0

E – Slightly Stable 15.1

F – Stable 33.9

This data indicates that over the monitoring period, the site exhibits trends of stable atmospheric conditions with 33.9% time during monitoring period. Stable conditions exhibit poor vertical mixing, and low levels of contaminant dispersion. Use of this stability data for modeling purposes will produce higher concentrations of pollutants at a given receptor (i.e. more conservative results). Mixing height Mixing Height (MH) is the vertical extent through which the contaminant plume can be mixed. Forecasting of mixing height is done with the aid of the vertical temperature profile. The MH is a function of stability. In unstable air the MH is higher and in stable air the MH is lower. With a lower MH, there is a smaller volume of air in which the pollutant can be dispersed, resulting in higher concentrations in the ambient environment. There is a seasonal variation of MH. During summer daylight hours, MH can be few thousand feet whereas for winter it can be a few hundred feet. It varies also in the course of a day. It is lowest at night and increases during the day. Secondary information has been used to determine the mixing height over the study region for the study period (Dec-2018 to Feb-2019) and it varies from 50-2500 meters (IMD). Potential Air Environment Impact Assessment During operation phase of project DG capacity provided of 3000 KVA will be expected as the main air pollution sources during. DG sets will be expected to run as back-up power supply during power failure. Thus, for air quality modeling study, it is assumed that the DG sets will be operated as on average four hours (0900-1200 Hrs) during daytime and four hours (1900-2200 Hrs) in the evening time per day. PM, SO2, NOx and CO will be expected as prime criteria air pollutants during the operation phase of the project. The isopleths showing the concentration of PM10, PM2.5, SO2, NOx and CO are shown in Figure-4.2 through Figure-4.6 respectively. Modeling result envisages that incremental ground level concentrations of modeled pollutants during operation phase of proposed project during the operation phase are negligible. The resultant concentration level of SO2, NOx and CO pollutants are expected to be well within the NAAQS.

4.5.2 Noise Environment

Any unpleasant sound is classified as noise pollution. Sound possesses three definite properties: intensity, frequency and duration. Intensity is the loudness of a sound, or the pressure it exerts through the ear. It is measured in decibels (dB). In assessing noise, a special measurement empirical parameter called "dB (A)" is used to assess the impacts on the human ear. The higher the dB (A) number, the greater is the risk of damage to hearing. Loud noise may adversely affect people in many ways. For example noise may interfere with sleep, speech, communication and can cause annoyance and other physiological problems. Occupational noise exposure, is also the most common cause of Noise-Induced Hearing Loss (NIHL), threatens the hearing loss among the individuals exposed to noise pollution for longer periods of time, at a less intense level. Noise Impact Assessment





The assessment of the impacts of noise on the surrounding community depends upon:

Characteristics of noise source (instantaneous, intermittent, or continuous in nature)

Time of day at which noise occurs

Location of noise source with respect to noise receptor For an approximate estimation of propagation of noise in the ambient air from the area or point source, a standard mathematical model for sound wave propagation used is as follows: Noise (Receptor) = Noise (Source) - 20 Log [distance (Receptor) / distance (Source)] For the modeling purposes, terrain is considered flat and there are no sound absorptive materials are present in the direction of the sound wave propagation so as to formulate the worst-case scenario. For the modeling purposes, terrain is considered flat and there are no sound absorptive materials are present in the direction of the sound wave propagation so as to formulate the worst-case scenario. For predicting noise emissions impacts due to proposed project, the noise emission sources are examined during both construction and operational phases. The noise levels during both distinct phases are predicted using the CPCB approved noise model DHAWANI applicable for stationary point sources. Construction Phase The project is expected to have large scale construction activities. Sources of noise emissions are expected from various construction equipments. The major noise generating sources envisaged during construction phase and their typical noise level value are given in Table-4.6. Table-4.6: Noise Levels Generated from Construction Equipment

4.5.3 Traffic Congestion/ Increase





Parking Provisions: Parking for 4024 ECS will be provided. Adequate parking space is provided within the project site on surface and in basements. Internal Road: Adequate parking space is provided within the project site in basements and surface.

All internal roads are 6 meter wide for smooth traffic flow. Service lane also provided with the project site to avoid traffic congestion at outside of

project site. One way traffic movement shall be followed to avoid traffic congestion.

4.5.4 WASTEWATER MANAGEMENT AND DISPOSAL

Mitigation Measures The estimated wastewater generation during the operation phase will be 605KLD, which shall be treated in onsite sewage treatment plant (STP) of capacity 725 KLD. The STP will be provided with primary, secondary and tertiary treatment facilities and is based on MBBR technology. Table-4.7 below shows the expected wastewater as well as treated wastewater characteristics. The schematic flow diagram of the STP is shown as Figure-4.7. Table-4.7: Characteristics of Wastewater and Treated Water

Parameters Raw Sewage (Incoming) Treated effluent from STP

pH 6.5-8.5 6.5 to 9.0

BOD @20C 250-300 mg/l Less than 20 mg/l

Suspended solid

200-400 mg/l Less than 50 mg/l

About 545 KLD of treated effluent will be generated, which shall be used in flushing purposes. This will reduce the domestic water demand efficiently. Regular maintenance check shall be carried out by the project proponent staff. Hence no major adverse impact on the water environment is envisaged. Sludge generated from the STP will be domestic in nature. The digested sludge will be stored in a room with RCC bottom and will be disposed off later on as manure in horticulture.





Figure-4.7: Schematic flow diagram of STP proposed

4.5.5 Solid Waste Mitigation Measures

As per the Central Public Health and Environmental Engineering Organization (CPHEEO) Manual on municipal solid waste.

The solid waste will comprise of biodegradable waste e.g. domestic waste, food waste, horticultural waste etc. and recyclable waste, like plastic, paper, tin, glass etc.

Different colored bins will be used for collection of biodegradable and non biodegradable waste as per MSW rules, 2016.

Private sweepers and MSW handlers will be appointed by the RWA for door to door collection.

Bio-degradable wastes will be composted in onsite organic waste converter. Non-biodegradable fraction like plastic, tin, glass etc. will be sold to local recyclers Horticultural waste shall be collected and disposed off with biodegradable waste. Rest inert Hazardous Waste Generation (DG Waste Oil) will be handed over to municipal

corporation for final disposal Used oil generated from DG sets will be stored in HDPE drums and sold to authorized

vendors.

4.5.6 Socio Economic Impacts

Induced Development This section discusses the project activities and the extent of the potential impacts anticipated from these. Based on the nature and type of impacts, the assessment has been divided into three category i.e. positive, negative and negligible impacts. For example the positive impacts are: job creation for men and women, better utilization of land, preservation of environment, and infrastructure development. Long term impacts have taken into account i.e. relocation, demography, aesthetics, accessing utilities, and impact on





archaeological sites. Negative impacts include adverse impacts on health, air pollution including noise, road safety, etc. Positive Impacts on Infrastructure The operation of the project, provide value addition to the existing infrastructure facility such as, office spaces, public transport, water supply, telecommunications, etc.

Job opportunity: During the social impact assessment process, meetings were held with the neighboring local settlements to listen to their specific concerns. The key question raised by the local community was the employment opportunities that would be generated in the area. The occupational profile of the region is such that the villagers can be a good source of labor during construction phase. This community can look forward to benefit due to more jobs and also better access to utilities. The benefit relate to the direct employment associated with the construction. Considering the increasing emphasis of employment and education in the village, the locals would have the opportunities for administrative or other supervisory jobs, closer to their place of stay. Expenditure incurred by those employed at the project will boost local economy in the village. Jobs would be created for unskilled, semi skilled as well as skilled labor category, for which locals would be given preference and there by the overall development of the region is envisaged.

Benefits to women: The proposed project would generate jobs for the women laborers during construction. Women are also likely to get job during construction phase. This will considerably reduce their travel time and therefore enable them to attend to their children and also other household chores.

Increase in Land Value: The prices of the land are likely to increase with the coming up of the project. Hence the proposed project will have beneficial impact.





5.0 ANALYSIS OF ALTERNATIVES (TECHNOLOGY & SITE)

5.1 Use of Environment Friendly Materials

Eco friendly building materials and construction technology will be used for the Project. a. Use of Ferro Cement: Reducing material use by use of ferro-cement wherever possible.

These are energy efficient and also help reduce the dead load of a building. b. Use of Fly Ash Bricks: Emphasis has been given on using eco friendly materials like fly

ash bricks in this project. There are lot of advantages which fly ash brick and fly ash lime brick enjoys over conventional bricks and are enlisted below:

Cost less to produce – at least 10% less than concrete bricks and 20% less than clay bricks.

Save construction cost – Due to the uniform shape and size of the fly ash brick, it saves labor in laying bricks by about 15%.

Use less energy – High amount of energy is consumed in heating clay bricks in kilns. By using fly ash bricks instead of clay bricks, energy is saved in brick manufacturing.

Reduce air pollution – Fossil fuel is used in heating clay bricks in kilns. Burning such fuel generates air pollution and greenhouse gas (CO2), contributing to global warming. By manufacturing fly ash bricks (at room temperature) instead of clay bricks (at over 2,000 oF), emission of air pollutants and greenhouse gas is avoided at brick plants, which helps to reduce air pollution and global warming.

Cleans indoor air – Recent research has shown that by using fly ash bricks indoors, the bricks adsorb mercury from the indoor air, causing the indoor air to be cleaner than the outdoor air.

c. Use of low VOC emissions such as cement and use of materials that prevent leaching. d. Material that are exceptionally durable, or require low maintenance e.g. PVC pipes will

be used.

5.2 Building Materials Use of alternative technologies for each component of the buildings of envelope, superstructure, finishes and the road and surrounding areas will follow National Building Code 2016 (N B C - 2016). Some of these are given below:

7.0 ADDITIONAL STUDIES

7.1 RISK ASSESSMENT

A disaster is a catastrophic situation in which suddenly, people are plunged into helplessness and suffering and as a result, need protection, clothing, shelter, medical, social care and other necessities of life. Disasters can be divided into two main heads. In the first head, the disasters result from natural phenomena like earthquakes, volcanic eruptions, storm surges, cyclones, tropical storms, floods, avalanches, landslides, forest fires. The second head includes disastrous events occasioned by man, or by man's impact upon the environment. Examples are armed conflict, industrial accidents, radiation accidents, factory fires, explosions and escape of toxic gases or chemical substances, river pollution, mining or other structural collapses, air, sea, rail and road transport accidents and can reach catastrophic dimensions in terms of human loss. There is no set criteria for assessing the gravity of a disaster in the abstract since this depends to a large extent on the physical, economic and social environment in which it occurs. However, all disasters bring in their wake similar consequences that call for immediate action, whether at the local, national or international level, for the rescue and relief of the victims.

7.2 Disaster Management Plan (DMP) The project encompasses the lives of a large number of people. It also involves installation of various structures and machineries that meet the comfort and need of its population but may also pose serious threat to the occupants in case of an accident. It is thus considered necessary to carry out a risk assessment and disaster management plan for the project. The Disaster Management Plan is aimed to ensure safety of life, protection of environment, protection of installation, restoration of production and salvage operations in this same order of priorities. For effective implementation of the Disaster Management Plan, it should be widely circulated and personnel training through rehearsals/drills. To tackle the consequences of a major emergency inside the site or immediate vicinity of the site, a Disaster Management Plan has to be formulated and this planned emergency document is called "Disaster Management Plan". The objective of the Disaster Management Plan is to make use of the combined resources of the project site and the outside services to achieve the following:-

Effect the rescue and medical treatment of casualties;

Safeguard other people;





Minimize damage to property and the environment;

Initially contain and ultimately bring the incident under control;

Identify any dead;

Provide for the needs of relatives;

Provide authoritative information to the news media;

Secure the safe rehabilitation of affected area;

Preserve relevant records and equipment for the subsequent inquiry into the cause and circumstances of the Emergency.

7.3 Risk Hazard & its control measures

It is attempted to plan and construct the buildings following all safety norms. However, it is not always possible to totally eliminate such eventualities and random failures of equipment or human errors. An essential part of major hazard control has therefore, to be concerned with mitigating the effects of such emergency and restoration of normalcy at the earliest. A detailed Table showing activity during construction and operation phase along with mitigation measures are given in Table-7.1. Table-7.1: Activities during construction and operation along with mitigation measures

7.4 Earthquake 7.4.1 Response Procedures for Occupants

If indoors:

1) Take cover under a piece of heavy furniture or against an inside wall and hold on. Stay inside: The most dangerous thing to do during the shaking of an earthquake is to try to leave the building because objects can fall on you. If outdoors: Move into the open, away from buildings, streetlights, and utility wires. Once in the open, stay there until the shaking stops. If in a moving vehicle: Stop quickly and stay in the vehicle. Move to a clear area away from buildings, trees, overpasses, or utility wires. Once the shaking has stopped, proceed with caution. Avoid bridges or ramps that might have been damaged by the quake. After the quake

1) After the quake be prepared for aftershocks.

2) Although smaller than the main shock, aftershocks cause additional damage and may bring weakened structures down. Aftershocks can occur in the first hours, days, weeks, or even months after the quake. Help injured or trapped persons.

1) Provide first aid where appropriate and not to move seriously injured persons unless they are in immediate danger of further injury. Call for help.

2) Remember to help those first who may require special assistance--infants, the elderly, and people with disabilities.





3) Stay out of damaged buildings.

4) Use the telephone only for emergency calls. 7.4.2 Response Procedure for Emergency Team 1) Formulate an Emergency Response Team for earthquake response.

2) Using the public address system, inform occupants of response procedures discussed

above.

3) Inform the necessary authorities for aid.

4) Ensure no person is stuck beneath any debris, in case of a structural failure. 5) Ensure that all occupants standing outside near the buildings are taken to open areas.

6) Ensure that the first aid ambulance and fire tender vehicles are summoned if necessary.

7) Inform the nearby hospitals if there are any injuries.

8) Check the utilities and storage tanks for any damage.

7.5 Seismicity

Based on the tectonic features and records of earthquake, a Seismic Zoning map has been developed for the country by Bureau of Indian Standard (BIS). The area under study falls under seismic Zone-IV (refer Figure-7.1) and thereby almost stable in nature. However suitable seismic coefficients in horizontal and vertical directions will be adopted while designing the structures. Seismicity of the proposed site will be taken into consideration during designing of the structural components of the development in the construction phase. The depth of the foundation, footing of the structural components, the bending moment calculations shall adhere to the criteria of seismic load. Necessary seismic factors, suggested by Indian Meteorology Department (IMD IS1893-Part I, 2002) shall be incorporated suitably, while designing the structures to safeguard against earthquake risks

7.6 Flood Flooding occurs when an extreme volume of water is carried by rivers, creeks and many other geographical features into areas where the water cannot be drained adequately. Often during times of heavy rainfall, drainage systems in residential areas are not adequate, or unchecked civil development severely impedes the functionality of an otherwise acceptable drainage system. Floods cause extremely large numbers of fatalities in every country, but due to India's extremely high population density and often under development standards, a large amount of damages and many deaths occurred. India witnesses flood due to excessive rain which then results in overflow of rivers, lakes and dams, which adds to cause large amounts of damage to people's lives and property. In the past, India has witnessed many of the largest, most catastrophic floods, causing irreparable damage to people's livelihood, property, and crucial infrastructure. 7.6.1 Flood in Delhi-NCR As per Flood Map of India (Fig:7.3), Delhi does not falls under flood prone area. Hence flood possibilities are very minimal. Figure showing Flood Prone map of India.





Figure 7.3: Flood Zone Map of India





7.6.2 History of Flood in Yamuna River, Delhi

7.7 Fire

Required response during in the event of a fire should be described in signs located in

the lobby.

On sighting a fire, it should be immediately informed to the facility manager giving the exact location and type of fire in detail.

Initiate the Emergency Response Team for fires.

If the fire is small, engage in extinguishing the fire using the nearest fire extinguisher.

Guide the Emergency Response Team staff to the emergency assembly point.

The Emergency Response Team should immediately inform the nearest dispensary and security force. If required a fire tender should be summoned.





The response team should immediately move to the point of fire and take all necessary steps to stop the fire. If the fire is not controllable and spreads then the manager in charge should inform the district authorities and call for external help.

The Emergency Response Team will provide immediate relief to the injured occupants at the scene of incident. Any injured persons should be evacuated on priority to the dispensary or one of the nearest hospitals based on their condition.
