CHAPTER – 11.1 INTRODUCTIONUrban areas have been recognized as “engines of inclusive economic growth”.Cit ies play a crucial role in evolution and advancement of culture, economyand polit ics. In 1950 only one person out of 5 people used to l ive in urbanareas in India. As per the 2011 census, out of the 121 crore Indian population,83.3 crore l ive in rural areas while 37.7 crore stay in urban areas,i.e.approx.32 % of the population. This is l ikely to be increased to 50% by year2030.

As per the 2011 census in India there are 4,041 Statutory Towns, 3894 censustowns, 475 Urban Agglomerations & 981 Out growths Urban areas aremanaged by urban local bodies(ULBs), who look after the ser vice delivery andgrievance redressal of cit izens. There are eight type of urban localgovernment in India- municipal corporation municipal ity, notif ied areacommittee, town area committee, cantonment board, township, port trustand special purpose agencies.

Migration is the key process underlying growth of urbanization in India andthe process of urbanization is closely related with rural to urban migration ofpeople. In most developing countries of the world where rate of urban growthis relatively higher the urban-ward migration is usual ly high. Rural to urbanmigration is by far the major component of urbanization and is the chiefmechanism by which urbanization trends all the world -over has beenaccomplished.

After independence, urbanization in India is increasing at very high pace, butat the same time there are some problems, which are becoming barriers forbalance, equitable and inclusive development.

1.2 INFRASTRUCTURAL CHALLENGES IN URBAN AREASHousingHousing provision for the growing urban popu lation will be the biggestchallenge before the government. The growing cost of houses comparison to



1-2


the income of the urban middle class has made it impossible for majority oflower income groups are residing in congested accommodation and many ofthose are devoid of proper ventilation, l ighting, water supply, sewage system,etc.

Safe Drinking WaterThe safe drinking water sources are also found to be contaminated becauseof water in the cit ies are inadequate and in the future, the expectedpopulation cannot be accommodated without a drastic improvement in theavai labil ity of water. The expenses on water treatment and reuse wil l growmanifold.

SanitationThe poor sanitation condition is another gloomy feature in urban areas andparticularly in slums and unauthorized colonies of urban areas. The drainagesystem in many unorganized colonies and slums do either not exist and ifexist ing are in a bad shape and in bits resulting in blockage of waste water.These unsanitary conditions lead too many sanitation related diseases such asdiahorrea and malaria. Unsafe garbage disposal is one of the crit ical problemsin urban areas and garbage management always remaine d a major challenge.

Health conditionsThe important indicators of human development are education and health.The health conditions of urban poor in some areas are even more adversecompared to rural areas. As many as 20 mill ion children in the developin gcountries are dying consequent to drinking water. About 6, 00,000 personsare losing their l ives on account of indoor air pollution (Jagmohan, 2005).

Urban public transportAs high income individual are buying more private vehicle and use less publictransport. Such huge number of vehicles in cit ies is causing more traffic jam,which in turn decreases the efficiency of public transport. Also thepenetration of public transport is less, which makes people use private



1-3


vehicle. Public transport is less di sabled friendly. There is also lack ofinfrastructure and poor maintenance of existing public transportinfrastructure.

Environmental concernsTo UNDP 70 % of Indian population is at r isk to f loods and 60% susceptible toearthquakes. The risk is higher in urban areas owing to density andovercrowding. Urban areas are becoming heat islands, ground water is notbeing recharged and water crisis is persistent.

The Green issues of urban areas, such as depletion of water, lack of sanitation,depletion of forest resources, the degradation of environmentally fragilelands, the occupation of f lood prone areas, Sol id waste management, airpollution, Noise pollution etc are increasingly visible

Urbanization consists of residential, commercial , institutional, industr ial ,recreat ional activit ies which contribute to the environmental degradation andunsustainable development. Thus al l future urban development activit iesincluding housing shall focus on green norms.

1.3 NEED FOR THE PROJECTThe twin cit ies of Hyderabad and Secunderabad are fast expanding for thepast 3 decades. The population of Greater Hyderabad Municipal Corporationis now at 67 lakhs as per the 2011 census and l ikely to reach 1 crore by 2020.Being an important destination of investment in the country in the areas ofIT, Pharma, Bio technology, Medical tourism and in many other knowledgebased industries, Hyderabad is playing vital growth engine not only forTelangana and also to the country.

Due to huge service sector growth, Hyderabad is attracting talent from variousparts of the country. Quality housing is most fundamental need for the urbanmiddle class. It is anticipated that there wil l 10% supply demand gap inhousing in Hyderabad in near future.Hence this project is envisaged to cater to middl e class and upper middle classpopulation of the city with all modern amenities.

2.6 WATER REQUIREMENT FOR THE PROJECT:Water is required for the construction as well as during occupation stage asthe same is an important resource. The water requirement duringconstruction is in the order of 100 cum/day with a peak demand of 200cum/day, and during occupation stage in the o rder of 1412 KLD.

2.6.1 Domestic Water Requirement:It is proposed to draw domestic water from the Hyderabad MetropolitanWater Supply and Sewerage Board (HMWSSB) to mitigate the drinking waterdemand, which has been encouraging bulk consumers. The water shortage ifany during summer season will be drawn from ground water sources. Duringthe construction stage, water wil l be sourced primarily through tankers thatwould be arranged by the contractor or bulk supplies from HMWS&SB. Duringthe project operational stage the water demand shall be sourced bulk suppliesfrom HMWS&SB. The water requirement of the project during occupationstage is in the order of 1412 KLD.

As it is envisaged to use treated sewage water for f lushing and green belt, thefresh water requirement would be 941 KLD. The water requirement for theproject during the occupation stage is presented in table 2.6. The watersavings for the project is presented in table 2.7

4.3 ENVIRONMENTAL IMPACT ASSESSMENTThe environmental impact assessment procedure proceeded simultaneouslywith detailed design of layout, and the structures. The important f indings ofthe assessment gave important feedback to the design team, especially interms of the valued eco components and the need for conservat ion ofresources. It helped modify the designs to incorporate solar energycomponent and water recycling component. The stepwise methodologyadopted for the EIA follows:

4.3.1 ScopingThe scope of the assessment for this study was determined by the Terms ofReference, the statutory requirements for the area of influence required bythe Ministry of Environment & Forests and consultat ion with experts. Aninit ial discussion with the project authorit ies and other stakeholders wasconducted in the study area to that the focus would be on valued ecosystemcomponents (VECs) they considered important.

4.3.2 Reconnaissance SurveysThe study team visited the project area and data was coll ected informationon various aspects l ike avai labil ity of infrastructure, terrain of the projectsite, disposal practices of municipality. The information collated has beenused for identifying the valued eco components to be chosen for specif icconsiderat ion in the study

4.3.3 Assembly and Analysis of DataThe data from surveys was fed to customized spreadsheets for ease ofanalysis. Supplementary information was col lected from Survey of India toposheets, census handbooks, HMDA master plan, FAR and Bui ld ing policy ofGOTS IT policy of GOTS and other government publications. Standardstatistical techniques were used for analysis of the socio - economic data, etc.Qualitative analysis was done for more descriptive data.

4.3.4 Documentation of Baseline Condi tionsThe documentation of the baseline conditions was completed for a 10kmradius circle from the site Project influence Area (PIA) as per the MoEF



4-3


guidelines. Pr imary surveys were carr ied out for determination of ambient airquality, water qual ity, noise qual ity and solid waste in sources at variousresidential, commercial receptors. A detailed ecology survey was alsoconducted.

4.3.5 Assessment of AlternativesAlternatives of the project s ite are not assessed in this case as the presentproject is site specif ic, however technology alternatives, disposalalternatives, and best f it layout alternatives were assessed.

4.3.6 Assessment of Potential ImpactsPotential signif icant impacts were identif ied on the basis of : analytical reviewof baseline data; review of land uses and environmental factors; analyticalreview of the socio-economic conditions within the PIA; and review ofassessment of potential impacts as identif ied by similar projects.

4.3.7 Integration of Environmental Impacts in the Design Proce ss:Environmental ComponentThe design and decision – making process integrated environmental and socialissues and prompted the early identif ication of appropriate actions. Suchactions included, for example, optimizing the layout and FAR, measures forwater conservation ,measures for solid waste management and energyefficiency measures for operational phase of the project were assessed

4.3.8 Identified Mitigation and Enhancement MeasuresMitigation measures for identif ied Signif icant impacts were addressed in EIAat different stages of construction and operational phase of the project .

4.3.9 Preparation of the Environment Management PlanEnvironmental Management plans have been prepared for the project andvarious variables and identif ied impacts separately as part of theEnvironmental Assessment. Responsibil it ies have been assigned for thevarious actions identif ied to l imit the adverse impacts of the project andbudget allocations have been made for the funds required for mitigat ion aswell as enhancement measures.



4-4


4.4 FINALIZING THE ENVIRONMENTAL ASSESSMENTThe field vis its-a part of the review exercise provided valuable inputs into thecompletion of the EIA. The baseline environmental setting, the potentialimpacts and the plausible mitigation m easures have been supplemented basedon the f ield visits and observations carried during the independent Review.

4.4.1 Completing the BaselineThe basel ine was updated by vis it ing the site and the PIA. The informationwas evaluated using the same environmental sensit ivit ies which wereidentif ied during the preparation of the draft EIA report . It is anticipated thatthe construction will be intrusive as the construction project is proposed onunderdeveloped land and the impacts wil l be l imited to a 1km distance fromthe construction/project site.

4.4.2 Impact Assessment and ModelingImpact assessment was carried out for the baseline environmental quality,which has been established at various receptors . Certain impacts which werenot considered during previous stages were also included. In addition, theupdated baseline and other information collected about sensit ive receptorsduring the subsequent site vis its provided the basis of making more concreteassessment of impacts

4.4.3 Mitigation and Enhancement MeasuresIn view of the presence of uneven terrain, appropriate mitigation measureswere chalked out for the project where adverse impacts could not be avoided.Enhancement measures including generic landscape plans, enhancement plansidentif ied are being prepared.

4.4.4 Environment Management PlanSince the EMPs are to become a part of the contract documents, they mustcontain all the information that may be required for the successfulimplementation of the mitigation and/or enhancement meas ures envisaged aspart of the assessment. Monitoring systems have been establ ished to ensureease up follow-up activit ies. In addition, the generic EMP for the activity has



4-5


been beefed up with inclusion of provisions related with other impactsidentif ied.

4.4.5 Environmental BudgetThe Budgetary provisions for implementing various environmental measureshave been rationalized for the project

4.4.6 Transfer of responsibil ity from Builder to AssociationsAdequate safe guards are suggested to be incorporated in transfer agreementof building to Association during operat ional phase on implementation ofEnvironmental Management Plan and to operate the environmentalinfrastructures such as STP, re -use of treated water , garbage col lection &disposal, Maintenance of land scaping etc., during operational phase.

5.3 WATER ENVIRONMENT5.3.1 Drainage Pattern and Water shed areaThe area forms part of the Ammenpur lake Watershed, and the Pacif ica AAVASsite is along the Northern periphery of the watershed Figure 5.6. A 1st orderstreamlet originates at the southwest of pacif ica site. Major part of thewatershed area is forming the pediment -inselberg complex, and dissected byephemeral streamlets flowing in a north-westerly direct ion towards theAmmenpur Lake. Being situated on an upland terrain, the study area isregional ly characterised by radial drainage. Some small and medium size tanksand water bodies are situated in the adjacent watersheds .

5.3.2 HYDROGEOLOGY5.3.2.1 Ground Water ConditionsGround water occurrence , movement and recharge to aquifers are controlledby the degree of weathering, fracture pattern, geomorphological setup andrainfall . Granites and Gneisses of peninsular gneissic group constitute majoraquifers in the area. Ground water occurs in phreatic condition in theweathered zone and under semi -confined condition in the fractured andjointed rock formations .

The common ground water abstraction structures are dug wells , dug -cum -bore wells and bore wells and their yields mainly depends on the rechargeconditions in the area . Howe ver, in recent years , due to urbanization,exponential growth in population and industrial units, demand for water hasresulted in indiscriminate dril l ing of bore wells . This has resulted indepletion of ground water levels, drying up of age old dug wells mainly due



5-14


to the over exploitation of the ground water resources . Due to increase innumber of bore wells and overdevelopment of ground water the yields inthe are a have fallen leading to failure of some wells . The depth o f the borewells in the area varies from 7 0 to 100 m, and even some dril led down to150 m are also common. The ground water yields gene rally range from< 1 .0 lps to 3.0 lps , with some instances up to 5.0 lps. The transmissivit iesof aquifers range from 19 to 190 m2/day and the specif ic yields of phreaticaquifers range from 0 .01 to 0 .4 (CGWB, 2007 & 2 013).

5.3.2.2 Ground Water LevelsBehaviour of ground water level is essentially controlled by physiography ,l ithology and rainfall . There is general decline and rise o f water during pre- and post -monsoon season. The rise s are due to the general build up ofwater levels in response to rains, and declines are due to erratic monsoon,less recharge (due to urbanization), and exploitation of groundwa terresources . Because of the moderate to deep water level conditionssubstantiated by the declining tren ds , the dug wells in the area have becomeobsolete, and ground water is mostly developed through deep borewe lls .

The depth to water levels in the area varies from <5 to >18 m bgl (belowground level). The dug wells usually show phreatic , and the borewe lls indicatesemi -confined conditions. There are four borewells located on the norther ns ide of the Pacif ica Complex , which were reported to be dril led down to100 to 120 m, with yields of 2 to 3 lps . During the f ie ld visit on 17th December2016, the depth to water levels in these borewells were observed, whichvaried from 10 to 12 m below ground le vel (bgl).

FIGURE 5.7 GROUND WATER FLUCTUATIONS OF OBSERVATORY WELLS INSTUDY AREA

The long term fluctuation data of two re presentative Central Ground WaterBoard (CGWB) monitoring stations situated near to the project site wereanalysed. These are located at Bachupal ly and Quthpullapur (Figure 1 ) , andthe analysed plots are shown in Figures 3 and 4. The CGWB has constructedpiezo meter (bore) well at Quthbullapur specif ically to monitor the groundwater levels. Overall the study area indicate s water levels respo ndingmoderately to the seasonal changes .

Analysis and calculation of water level f luctuation data for the yea rs rangingfrom 2005 to 2013 indicated seasonal declines and rises , with noticeablerise in the long term data . The depths of the water levels of these twomonitoring stations, along with seasonal water level f luctuations , vary from2 to > 14 m bgl. Base d on the monitoring analysis , the areas indicate longterm rises ranging from 0.03 to 0 .20 m per annum (Figures 3 and 4 ) . The longterm gentle r ising trends may be due to the presence of many percolat iontanks and water bodies l ike Ammenpur Cheruvu, Miyapur Cheruvu andsubsequent ground water recharge in to the aquifers . The prevalence of



5-16


ground water recharge structures in the area might have also contributed tothe long term rise of water levels.

5.3.2.3 GROUND WATER RESOURCES ESTIMATIONIn collaboration with the state departments , Central Ground Water Board(CGWB) carr ied out ground water resource estimation and categorizationstudies for the Quthbullapur Mandal of Ranga Reddy Distr ict for the year2008 -09. The CGWB has categorized the area as ‘ safe’ with the stage ofground water uti l izat ion of 18% , indicating good scope for further groundwater development. These details are applicable to the study area also , asit is forming part of the Quthbullapu r Mandal.

5.4 Water Quality studiesThe development of any region is contingent on the availabil ity ofsufficient water resources , as residential & Commercia l complexes wouldrequire water for domestic consumption. The potential for exploitation ofground water resources increases as development of new projects increasesin Urban and Semi Urban areas . With the increasing industrializationand urbanization the possibil it ies of contamination of surface waterand ground water sources are rapidly increasing. The water resources in thearea broadly fall into following categories:1. Surface Water resources : Streams and ponds , e tc .2. Ground Water resources : Accumulation in deeper strata of ground.

5.4.1 Surface Water QualityIn order to have an idea of quality of water f lowing in the region,representative water samples were collected and analyzed according tothe surface water standards ; I S: 10500 - 1991 . The representat ive surfacewater sampling locations are shown in Figure 5.8 and analysis results arepresented in Table 5.4

5.4.2 Ground Water ResourcesGround water is the accumulation of water below the ground surface , causedby rainfal l and its subsequent percolation through pores and crevices.Percolated water accumulates t i l l it reaches impervious strata consisting ofconfined clay or confined rock s. Occurrence of ground water is controlledby land form, structure and l ithology.

Ground water abstraction is by means of dug w ells , dug cum driven wells, andbore wells and open wells near the seacoast areas . Ground water resourcesare ample in the study area . Every vi l lage has a number of traditional wellslarge and small . The state authorit ie s have also provided tube wells f ittedwith hand pump for the drinking water requirement of vi l lages in the studyarea . Presently the drinking water needs are most ly met from the groundwater resources.

5.4 .2 .1 Qual ity of Ground WaterThe quality of ground water occurring in the geological formations in thestudy area is general ly good in most of the areas . The representative samplesare col lected from various dug wells and bore wells in the s tudy area . Theanalytical results of water samples drawn from various locatio ns in the studyarea are presented in Table 5.5 . The map showing the locations of groundwater sample col lect ion is Figure 5 .9

5.5 Air Environment5.5.1 MeteorologyMicro meteorological studies are simultaneously conducted with the airquality monitoring. Methodology plays a vital role in effecting the dispersionof pollutants, once discharged into the atmosphere, their transport,dispersion and diffusion into the environment. The meteorological data is veryuseful for interpretation of the baseline information and for model study ofair qual ity impacts also. Since meteorologic al data show wide f luctuationswith t ime, meaningful interpretation can only be drawn from long term andreliable data. Such source of data is the India Meteorological Department(IMD) that maintains a network of meteorological stat ions at severalimportant locations. The data recorded for nearest IMD station at Rangareddyis summarized for the period 1981 to 2010 and the same is Presented in Table5.5

5.5.3 Ambient Air Quality

Air pollution means the presence in the outdoor atmosphere of one or morecontaminants or combinations there of in such quantit ies and of such durationas are or may tend to be injurious to human, plant or animal l ife or property.Air pollutants include smoke, vapors, soot, fumes, gases , mist, odors,particulate matter , radioactive material or noxious chemical . Withupcoming industrial activity a range of different pollutants are releasedinto the atmosphere that are dispersed and have a s ignif icant impact onneighborhood air environment. Thus collection of base l ine da ta o fair environment occupies a predominant role in the impact assessmentstatement. The ambient air quality status across the study zone forms basisfor prediction of, the impacts due to the proposed project.

The data required to assess air quality impacts in and around neighbor hoodis achieved by designing such a network , which encompasses micrometeorological conditions, quantity and quality of emissions , locat ions ,duration, resources/monitoring technology and operational criter ia. Theoptimal scheme for air quality monitoring should consider all the abovefactors.

5.5.3.1 Scope of Field Study

The scope of baseline status of the ambient air quality can be accessedthrough a wel l-designed ambient air quality stations network . An intensiveambient air quality monitoring of the study are a cons is t ing of 10 k m. radiuswith the proposed project site as the center point was carr ied out duringthe period from November 2016 – January 2017 . The ambient air quality wasmonitored at six locations spread over entire study area. Figure 5.7 presentsthe locat ions of ambient air quality - monitoring stations. At each samplingstation monitoring was carr ied out for 24 hours in a da y for 2 days a week,and for three months . The major air pol lutants mo nitored on 24 hourly basesare PM1 0 , PM2 . 5 , Sulfur dioxide and Oxide s of Nitrog en.

Sampling and analysis of the above variables is according to the guide l ines ofCentral Pol lution Control Board.

5.6 Noise EnvironmentNoise is a n unwanted sound without musical quality. Artif ic ial noise and itsimpact on environment, grown apace with advancing human civil izat ion.Noise pollution is equally hazardous to environment as air, water and otherforms of pollution. Various noise meaurement units have beenintroduced to describe, in a s ingle number, the response of an average humanto a complex sound made up of various frequencies at different loudnesslevels. The most common scale is, weighted decibel dB (A), measured as therelative intensity level of one sound with respect to another sound (referencesound).

The impact of noise depends on its characteristics (instantaneous,intermittent or continuous in nature), t ime of day (day or night) and locationof noise source.

The assessment of noise pollution o n neighborhood environment dueto the proposed industry was carried out keeping in view, all theconsiderations mentioned above. The exist ing status of noise levels ismeasured at 7 locations at various sampling locations including the site withinthe study area. Figure 5.11 shows noise level measured locations. Themeasured noise values are shown in Table 5.9.

5.7.3 Primary data collectionA stratif ied random sampling technique was followed to select the samplevil lages and households. Accordingly, the sample vil lages were picked up atrandom from the three impact zones considered – core, buffer and transit ion.The number of households to be contacted in each sample habitation/vi l lagewas determined on the basis of the size of population of the respectivevil lage. In the absence of household level information, the respondenthouseholds were selected randomly during the course of visit to therespective habitation/vil lage. However, whi le selecting the respondenthouseholds, emphasis was on contacting households, who are economicallypoor, susceptible to shifts in l ivelihood patterns and belonged to vulnerablesocial communities. Accordingly, the sample habitations/ vil lages selected forthe survey together with the number of households across each vi l lage arepresented in Table – 5.12

5.7.6 Aspirations and ApprehensionsAs revealed during focus group discussions, nearly 85% of the respondentsare aware of the industrial growth in the area, but less than 20% are awareof the proposed project. While they are convinced with the posit ive impactsof industrial development in the area, they are also wary of the negativeimpacts on the surrounding environment. The perceptions of the respondentsas regards the establ ishment of more industrial projects in the area could besummarised as follows:

Industrial growth in the region has signif icantly supported thesustainable l ivel ihoods in the area especially for skil led and semi-skil ledpersons.

Development of the secondary sector in the area has posit ivelycontributed to induced development leading to creation of multiplierself and wage employment opportunities.

It would help further strengthen infrastructure d evelopment in thearea.

The groundwater resources in the area have severely depleted andcontaminated.

It may aggravate air pollution through release of obnoxious gases andodors.

5.8 Biotic EnvironmentScope of work for this study is in l ine with the ToR assigned to the companywhich include identif ication of ecologically sensit ive receptors based onliterature survey and field investigations, prediction of impacts and theirmitigation with conservation action plan. The study was carr ied out in corearea (project site) and in buffer area i.e. 10.0 km periphery from the projectsite. The study was carried out scientif ically using primary and secondary datain order to bring out factual information on the ecological conditions of theproject site and its surroundings. Biological assessment of the site was doneto identify the presence of any Rare or Endangered or Endemic or Threatened(REET) species of f lora or fauna in the project site or core area as well itsbuffer zone and to identify whether there are any ecological ly sensit ive areawithin the area that is l ikely to be impacted (buffer zone). The study alsodesigned to suggest suitable mitigation measures if necessary for protectionof wildl ife habitats conservat ion of REET species if any.The following eco sensit ivity is observed for the site

5.8.2 ECOLOGICAL PARAMETERSEcological parameters viz., abundance, density, frequency,

Relative abundance (RA), Relative density (RD),Relative frequency (RF), Important value index(IVI), Shannon-Wiener diversity index were

derived from the quantitative primary data col lected during f ield survey.Importance Value Index (IVI): RD + RF +RASpecies DiversityShannon Diversity Index (H’) has been used for estimating the diversity amongthe core & buffer zones in order to know the species richness and dorminance.H’= - Pi. ln PiS= Number of individuals of one species Where Pi = --------------------------------------------------------N = Total number of all individuals in the sample and, ln is the logarithm tothe baseShannon – Wiener Indices of Diversity vary depending upon the speciesrichness (number of species present in a given unit area) and their dominanceor evenness. As the species richness and evenness increase, Shannon – WienerIndices of Diversity also increase correspondingly. On the other hand, whenthe species r ichness decreases and as dominance increases, diversitydecreases. Communities with less number of species with high level of



5-48


dominance or low level of uniformity wil l h ave lower diversity. Thus it is astatistical function based on the richness and evenness components.Evenness and dominance are inversely related.

This can be also calculated through Statistical Software “ PAST”.

5.8.3 Floral studyPresent environmental setting:

Core zone: The project site is a private land with man made ecosystem withfew selected trees, shrubs and herbs. Entire area is with terrestrial vegetationis without any forest or agriculture land and it was devoid of any ecologicallysensit ive biological resources. There are no REET species present in the corezone. No migratory corridors or breeding grounds for faunal species presenthere.

At present there is no green belt within their site premises. Some space wasallotted to raise specif ic p lants in core zone. No special precautions weremade towards conservation of faunal diversity. The common butterfl ies,dragonflies, birds and smaller mammals were sighted here.

CHAPTER – 66.1 Assessment of Environmental ImpactsThis chapter assess the nature and type and magnitude of potentialenvironmental impacts l ikely on physical, biological and social environmentalcomponents due to the implementation of project at different stages

6.2 Back Ground of The ProjectM/s. Pacif ica India Projects Pvt Ltd., proposed to develop a residential projectat Sy. No. 311,312,313,316 & 317 situated at Bachupal ly(V), Q uthbullapur (M),Ranga Reddy (D), Telangana. The project would cater to various marketdemands and needs of the people. The project site is surrounded by existingresidential colony by name Reddy Colony, Prajay Shellters and Swarnapuri onSouth, and vacant land of neighbours on Nothern and Western directions.

The Site is connected to Old Mumbai Highway by Miyyapur – Bachupally (12Meters Road expanding 45 m) in the Eastern side at a distance of 2 KM. Thesite is adjacent to Cooco cola Road which is curre ntly 9 Meters Road butexpanding to 30 Meters Road. The impacts of the proposed project can occurduring construction and Occupational stages

6.3 Impact on Micro Meteorological parameters:The project is located in a semi arid tropical region in Deccan Pl ateau. Noimpact is envisaged on macro –cl imatic settings of the region as scale of theproject is not so huge. The micro cl imate, particularly the ambienttemperature may be modified sl ightly due to paving of the virgin land. Therecan be increase of day time temperature marginally with in the project area.The temperatures in the region in summer will touch up to 44 DegreesCentigrade. The affect of increase in temperature wil l be more on pedestriansand slow moving traffic. In order to mitigate this, it is proposed to developgreenery in about 10 % of the site. Walking tracks & Cycle tracks shall be keptas unpaved with grass



6-2


6.3.1 Cool RoofThe cool roof materials have two important properties; high solar reflectanceor Albedo and high thermal emittance. Solar reflectance and thermalemittance have noticeable effects on temperature. Conventional roof surfaceshave low reflectance (0.05 to 0.2 5) and high thermal emittance (typically over80%) and heat up to 150 to 190°F (66 to 88°C) at midday during the summer.Bare metal or metall ic surfaced roofs have high solar reflectance (0.5 orhigher) and may have low thermal emittance (20 to 60%, depend ing on theirsurface treatment) and warm to 140 to 170°F (60 to 77°C). Cool roofs withboth high reflectance and high emittance warm to only 100 to 120°F (38 to49°C) in the summer sun.

Most cool roof appl ications have a smooth, bright white surface to reflectsolar radia t ion, reduce heat transfer to the interior, and save on summertimeair conditioning. These properties also can extend the l ife span of a roof. Bylimiting the quantity of absorbed solar energy, damage from ultravioletradiation and daily temperature f luctuations — which cause repeatedcontract ion and expansion — can be reduced. The albedo values of variousroof materials are presented in Table below

Table. 6.1 Albedo values of various types of roof materialS. No Roof Material Albedo Values

1 Highly Reflective Roof 0.6 – 0.72 Corrugated Roof 0.1 -0.153 Colored paint 0.15-0.354 White Paint 0.5-0.905 Tar & gravel Roof 0.03-0.186 Red/Brown Tile Roof 0.10-0.35

As the roofing in this case is RCC, the colour choice of the exteriors and theroof play important role.



6-3


6.3.2 Other Alternative - Green RoofsGreen roofs are an attractive roofing option that can reduce urban heatislands by providing shade and through evapo-transpiration, therelease of water from plants to the surrounding air. The benefits ofgreen roofs include:

Reduce sewage system loads by assimilating large amounts ofrainwater.

Absorb air pollution, col lect airborne particulates, and storecarbon.

Protect underlying roof material by eliminating exposure to thesun’s ultraviolet(UV) radiation and extreme daily temperaturefluctuations.

Serve as l iving environments that provide habitats for birds andother small animals.

Offer an attractive al ternative to traditional roofs, addressinggrowing concerns about urban quality of l ife.

Reduce noise transfer from the outdoors. Insulate a building from extreme temperatures, mainly by

keeping the building interior cool in the summer.

However being high raise building, the green roof option would be usefulfor top f loor. For the rest of the building, it is suggested to select based onalbedo factor to avoid the low thermal emittance

6.3.3 Trees and VegetationPlanting trees and vegetation is a simple and effective way to reduce heatislands. Widespread planting in a city can decrease local surface and airtemperatures. Strategic planting around -homes and buildings directly coolsthe interior of homes and buildings, decreasing air conditioning costs an dpeak energy demand.

Trees and vegetation cool the air by providing shade and through evapotranspiration, (the evaporation of water from leaves). Shade reduces theamount of solar radiation transmitted to underlying surfaces, keeping them



6-4


cool. Shaded wal ls may be 9 to 36°F (5° to 20°C) cooler than the peak surfacetemperatures of unshaded surfaces. These cooler walls decrease, the quantityof heat transmitted to buildings, thus lowering air conditioning cooling costs.Cooler surfaces also lessen the hea t island effect by reducing heat transfer tothe surrounding air .

Transmittance varies by tree or vegetation type, but for deciduous species— which shed their leaves in winter— Transmittance ranges from 6 to 30% in the summer and 10 to 80% in thewinter.

Another way trees and vegetation cool the air is by absorbing water throughtheir roots and evaporating it through leaf pores.. Evapotranspiration alonecan reduce peak summer temperature reductions of 1 to 50c. While thisprocess reduces air temperatures, it does add moisture to the air.

Deciduous trees work well , as they balance energy requirements over thecourse of a year. In summer, foliage cools buildings by blocking solarradiation. In winter, after the leaves have fallen, the sun's energy passesthrough trees and helps to warm buildings.

6.3.4 Cool PavementsWhile studies show that pavements can affect the urban heat island andresulting air quality, results are complicated by several factors. These includethe impact of shadows from nearby structures; changes in pavementcharacteristics over t ime; and the absorption by buildings of solar radiationreflected from the pavement surface. There are situations, however, wherecommunities interested in reducing heat island effects can choose pavingmaterials that lower surface temperature and achieve related objectives.

It is proposed to provide pathways in the residences by way of Permeablesurfaces using lattices f i l led with soi l , gravel, o r grass. The measures proposedto reduce the heat is land effect is presented in table 6.2

6.4 NATURAL AND BIO PHYSICAL ENVIRONMENT6.4.1 Air EnvironmentAir quality wil l be impacted both during the construction and operation stagesof the project. Construction stage impacts wil l be of short term in nature andhave adverse impact on construction workers as well as the residentiallocalit ies adjoining to the site especial ly those in down wind direction,Operation stage impacts wi l l not be as severe as construction stage impacts.The impacts and mitigation measures are discussed

6.4.2 Generation of DustPre-construction & Construction stagesGeneration of dust is the most l ikely impact during these stages due to siteclearance and use of heavy construction equipment of digging of foundationand fi l l ing, Transportation of raw material, c oncrete batching plant. Barringtop soil up to 2 Meter depth, the sub soi l of the site is sheet rock.

6.5 Impacts on Water Resources:Three possible impacts on water resources from the implementation of the projectas detailed below

Water consumption – Both during construction and duringoccupation

Waste water discharge – Both during construction and duringoccupation

Storm water generation – Once the project is completed

6.5.1 Impact on Water Consumption:In regards to water consumption, the water usage during construction would be inthe order of 200 m3/day on peak demand both for construction activity and fortemporary shelters to work force. During Occupational stage, the Fresh waterrequirement would be 874.58 m3/day by considering the recycl ing of treated sewagewater for f lushing and gardening purpose.

Water during construction stage is drawn from ground water source supplementedby private tankers. Water during occupational stage would be sourced fromHWWS&B. Hence impact on ground water is l imited to construction stage only. Onpositive side it is proposed to develop water harvesting structures to augmentground water resources

6.5.2 Impact from Waste water discharge:During construction stage sewage water from workers temporary shelters would begenerated. The total work force to whom temporary accommodation will be createdis 100 faimil it iesie. 500 persons. Thus waste water generation from toilets would beabout 40 m3/day. Temporary toilets would be provided with sept ic tanks. Once workis completed, the septic tanks would be cleaned and sent to GHMC waste watertreatment facil it ies

During occupational stage, the waste water generated would be in the order of 1341m3/day. It is proposed to establish STP’s with 1350 m3/day capacity to treat theeffluents.

6.5.2.1 Sewage treatment plantDescription of Sewage Treatment Plant Sequential Batch Reactor (SBR)TechnologyThe Sequential Reactor (SBR) is a modif ication of activated sludge processdesigned to operate under non-steady 'state conditions also. An SBR operatesin a true batch mode with aerat ion and sludge settlement both occurring inthe same tank. The major differences between SBR and conventionalcontinuous -flow, activated sludge system is that the SBR tank carr ies out thefunctions of equalization, aeration and sedimentation in a time sequencerather than in the conventional space sequence of continuous -flow systems.In addition, the SBR system can be designed with the abil ity to treat a widerange of influent volumes whereas the continuous system is based upon afixed influent f low-rate. Thus, there is a degree of flexibil ity associated withworking in a t ime rather than in a space sequence.

SBR's produce sludge's with good settl i ng properties, provided the influentwastewater is admitted into the aeration in a controlled manner. Controlsrange from a simplif ied f loat and timer based system with a PLC

An appropriately designed SBR process is a unique combination of equipmentand software. Working with automated control reduces the number ofoperator skil l and attention requirement.

The majority of the aeration equipment of Sequential batch reactors consistsof f ine bubble and coarse bubble aeration systems.

This system can adapt to the changes in the influent quality of wastewaterthan any other process due to the change in the use of the chemicals /procedures as in case of the Hotels/ laundries etc.

Sequential Batch Reactor Process CyclesThe operating principles of a batch activated sludge process, or SBR, arecharacterized in six discrete periods:Anoxic Fi l lThe influent wastewater is distributed throughout the settled sludge through



6-15


the influent distribution manifold to provide good contact between themicroorganisms and the substrate. The influent can be either pumped in orallowed to f low in by gravity. Most of this period occurs without aeration tocreate an environment that favors the procreation of microorganisms withgood settl ing characteristics. Aeration begins at the beginning of this period.

Aerated Fil lMixed l iquor is drawn through the manifold, mixed with the influent flow inthe motive l iquid pump, and discharged, as motive l iquid, to the jet aerator.This init iates the feast period. Feast is when the microorganisms have been incontact with the substrate and a large amount of oxygen is provided tofacil itate the substrate consumption. Nitrif ication and denitrif icat ion occursat the beginning of this stage. This period ends when the tank is either full orwhen a maximum time for f i l l ing is reached.

ReactDuring this period aeration continues until complete biodegradation of BODand nitrogen is achieved. After the substrate is consumed famine stage starts.During this stage some microorganisms wil l die because of the lack of foodand will help reduce the volume of the settl ing sludge. The length of theaeration period determines the degree of BOD consumption.

SettleAeration is discontinued at this stage and solids separat ion takes place leavingclear, treated effluent above the sludge blanket. During this clar ifying periodno l iquids should enter or leave the tank to avoid turbulence in thesupernatant.

DecantThis period is characterized by the withdrawal of treated effluent fromapproximately two feet below the surface of the mixed l iquor by the floatingsolids excluding decanter. This removal must be done without disturbing thesettled sludge.

Idle



6-16


The time in this stage can be used to waste sludge or perform backwashing ofthe jet aerator. The wasted sludge is pumped to an anaerobic digester toreduce the volume of the sludge to be discarded. The frequency of sludgewasting ranges between once each cycle to once every two to three monthsdepending upon system design.

Aeration Equipment:As usual with 'Activated sludge process'

ConclusionWastewater treatment has been a challenge throughout the years due tovarying influent chemical and physical characteristics and stringent eff luentregulations. Treatment systems using activated sludge have been able tohandle many of these diff icult ies. Given the lack of on-line computer controls,continuous f low systems have been mostly used for these purposes versusSequential batch processes. The availabil ity of artif icial intell igence has nowmade the option of a SBR process more attractive thus providing bettercontrols and results in wastewater treatment. This is coupled by the f lexibil ityof a SBR in the treatment of variable f lows, minimum operator interactionrequired, option for anoxic or anaerobic condition s in the same tank, goodoxygen contact with microorganisms and substrate, small f loor space, andgood removal eff iciency.

Sequential batch reactors operate by a cycle of periods consist ing of f i l l , react,settle, decant, and idle. The duration, oxygen co ncentration, and mixing inthese periods could be altered according to the needs of the particulartreatment plant. Appropriate aeration and decanting is essential for thecorrect operations of these plants. The aerator should make the oxygenreadily avai lable to the microorganisms. The decanter should avoid the intakeof f loating matter from the tank. The many advantages offered by the SBRprocess just ify the recent increase in the implementation of this process inindustrial and municipal wastewater treat ment.

Sequential Batch Reactor (SBR) tankBiological stabil ization of the wastewater is accomplished in the SBR tank inthe presence of microorganisms, for the respiration of which oxygen issupplied by means of diffused aeration comprising of membrane diffusers andair blowers. As micronutrients such as nit rogen and phosphorus wil l bealready present in sufficient quantit ies, no external supplementation will benecessary.

The aeration tank is provided with diffused aeration system to supply the airfor the microorganism’s growth. The nutrients required for themicroorganism’s growth are organic matter, which is present in the domesticeffluent.

The MLSS level is maintained in this process to enhance the aeration process.Optimum concentrat ion of MLSS to be maintained is in the range of 3500 –4500 mg / l it . During the aeration, the sludge starts to settle in this tank. Atthat t ime, the blower wil l be off.

Here the settl ing of the solids takes place and the clear water from the top ispumped to the clear water tank.Design f low = 1,35,0000 Lt/dayConsidering the 3 batchesVolume of the tank = 1350 / (3 batches x 4 reactors x 0.5 decanting ratio)

Sludge Disposal:The biomass in the aeration tank stabil izes BOD in wastewater by consumingthe organic matter in the wastewater. The metabolic activity results in growthof the biomass population in the aeration tank. Consequently, in order tocontain the level of MLSS in the aeration tank to the design level of 4000mg/l ,it wi l l be necessary to bleed off or waste the excess act ivated s ludge. For this

measures proposed for the project which wil l mitigate the impacts due toexploitation of the natural resource of water is as follows; Recycling: All theapartment blocks are provided with treated water recycling for f lushingpurposes which wil l recycle about 40 I/head/day. The saving in waterrequirement is in the order of 0.3Iakh l itres/day.

The delivery system of water in the households is mainly by f lush system andvarious facets in the toilets and kitchen. The water consumption in the f lushsystem will be reduced by provision of f lush systems which have regulatorsand with a capacity of 8 I/f lush. It is proposed to provide faucets with halfturn valves, and foam flow water saving aerators. These faucets wouldensure lower water consumption, as the pressure remains the same with lesswater quantity. The faucets wil l be leak proof, as a drip/second leak wouldlead to a loss of 30 1/day of water. The saving in water requirement ispresented in table 6.1 2the mitigation measures are tabulated in table 6.13

6.6.3 IMPACT OF STORM WATERStrom water drains wil l be provided all over the site to meet the expected increasein the runoff during rainy seasons due to the impervious nature of the roads andother paved areas. The site is uneven and it is proposed to maintain the levels asmuch as possible, hence 2 numbers of storm water let outs from the site areanticipated. The expected runoff is calculated for the design of the storm waterrunoff and presented below

6.6.3.1 Calculation for Storm WaterQuantity of Storm water:

6.7 Land6.7.1 PhysiographyThe impact of project on physiography is a function of the terrain of the area. It ismost drastical ly altered in case of hil ly terrain or where extensive cut-and-fi l loperations are involved. The project area has a rocky terrain and the design stagedeliberations have ensured that the major contours are not disturbed and rocky partis kept for subsequent development of green space. However the physiographyimpact wil l be signif icant non -reversible, as the contours of the area wil l bedisturbed. The cut and fi l l operations may cause air pollution, clogging of drains andsolid waste for disposal . The design stages has optimized the cut and fi l l operationsand the excess cut material is minimum and the same shall be reused for theconstruction purposes.

6.7.2 SeismicityThe project site is located in Zone I I. These are relat ively stable areas.ProjectConstruction in this area wil l have l itt le impact on its overall earthquake potentialsince no major blasting is envisaged at the construction site.

6.7.3 Loss of productive soil Pre-construction stageThe area of the project is non -agricultural barren land and has been classif ied asresidential zone by HMDA. The present usage of land is barren and the developmentof the land wil l have a posit ive impact on the aesthetics.

Construction stageThe soils of the project site are sandy loam. Soils in the project site may benegatively impacted due to the proposed project . The loss o f productive topsoil dueto construction is a direct adverse long -term impact. However the land usage atpresent is barren and the project would have a posit ive impact during occupationsstage. Mitigat ion measures are to be adopted for preservation of topsoil.

Occupation StageThe project wil l have a posit ive impact on the soils and soil quality as the projectwil l have greening program and the soils wil l be protected due to conservation.



6-6


6.7.4 Soil ErosionThe soil in the study area varies from sandy loam to Sandy. Therefore the potentialfor erosion is low. Erosion will be exacerbated if the vegetation is removed from thesite since roots are known to hold soi l together. This wil l however be for theduration until the compensatory afforestation and roadside plantation havematured. It is not possible to construct projects without removing trees anddisturbing the contours. However, to prevent the eroded material from entering thewatercourse, s i lt fencing can be provided at the end of ditches or cascadearrangements can be provided at the end of ditches as they enter the watercourse.While the former requires frequent cleaning to prevent built -up, the voids in thecascade wil l be f i l led up by eroded material and eventually vegetation wil l beestablished there. No soil erosion is anticipated as greening activity wil l mitigatesoil erosion.

6.7.5 Contamination of Soil Pre-Construction StageContamination of soil in the pre -construction stage may be considered as a short -term residual negat ive impact. Soil contamination may take place due to solid wastecontamination from the labour camp set up &king pre-construction stage.

Construction StageContamination of soi l during construction stage is primarily due to construction andall ied activit ies. The sites wh ere construction vehicles are parked and serviced arelikely to be contaminated because of leakage or spil lage of fuel and lubricants.Refuse and sol id waste from labour camp can also contaminate the soi l.Contamination of so i l during construction might be a major long-term residualnegative impact. Unwarranted disposal of construction spoi l and debris wi l l add tosoil contamination. This contamination is l ikely to be carried over to water bodiesin case of dumping being done near drain body locations.Occupation StageDuring the occupation stage, soil pol lution due to garbage dumping at unauthorizedlocations, accidental spil ls or leaks is a low probabil ity incident.

6.8Solid WastesSolid wastes of different variety are anticipated from the construction and

occupation stages of the project. The Impacts of solid wastes if unmitigated couldbe environmental ly disastrous and economically expensive to mitigate at a laterstage. The wastes anticipated and the impacts are tabulated in table 6.15

The cut material contains mainly granite stones, which is suitable for aggregatepurpose. The excess cut material if any wil l be used for the purpose of aggregatefor laying roads

Construction DebrisAs per the Construction &Demolit ion waste Management Rules 2016 notif ied by



MOEF, the construction debris shall be managed by the proponents duringconstruction stage. Wherever possible construction debris would be used as f i l lmaterial for roads construction. Any excess material is generated same would bedisposed to identif ied municipal waste disposal facil ity in consultation with GHMC

Occupation Stage:The total number of people anticipated to stay in the housing project is in therange of 10000-11000. The anticipated solid waste/garbage is in the range of500g/head, and the total garbage will be in the order of 5828.3 kg/day.

As the area is under GHMC limits, garbage col lect ion system is in place. Two binsystem implemented by Government of Telangana as a part of Swatch Bharatinit iative would be followed. Adequate storage area for garbage is proposed nearSTP to collect and dispose to Municipal so lid waste management system.

The table 6.17 presents the anticipated garbage quantity after occupation andTable 6.18 gives the characterization and composition of l ikely garbage.

The material requirement during construction stage has both posit ive and negativeimpacts as the requirement of resources which are industrially produced will g iveimpetus to industr ial growth. While the unsustainable natural resourcesrequirement of sand will have negative impact at the mining areas . It is necessarythat the sand is transported from the areas identif ied by Government. Themanmade resources l ike Cement, Steel, Bricks, and Ti les would need mineralswhich are unsustainable, and yet the necessity of development compensates theimpacts.



6.9 NoiseThough the level of discomfort caused by noise is subjective, there is a definiteincrease in discomfort with an increase in noise levels. Project tends to cause noiseindirectly as the roads provided for connectivity would lead to increased noiselevels. Road noise depends on factors such as traff ic intensity, the type andcondition of the vehicles plying on the road, acceleration/deceleration/gear changesby the vehicles depending on the level of congestion and smoothness of ro ad surface(IRC: 104-1988).

The basel ine noise levels monitored at various locations in the project impact areaindicate the baseline levels exceed the permissible l imits for residential and ruralareas during day-time specif ied by the CPCB for residential areas. The impacts onnoise due to the project wi l l be of signif icance in both the construction as well asthe operation stages.

Pre-Construction stage:Noise levels during the pre-construction stage are most ly expected to be indicativeof prevalent basel ine levels apart from localized noise levels at locations where •pre construction stage activit ies are taking place such as establishment of workerscamps, stockyards. These increased noise levels wi l l prevai l only for a short durationduring the pre-construction stage. Moreover, as these activit ies are not l ikely to beplaced near settlement locations the increased noise impact is bound to benegligible.

Construction Stage:Due to the various construction act ivit ies, there wil l be temporary noise impacts inthe immediate vicinity of the project corridor. The construction activit ies wi l linclude the excavation for foundations and grading of the site and the constructionof structures and facil it ies. Asphalt production plants, movement of heavy vehicles,loading, transportation and unloading of construction materials produce signif icantnoise during construction stage. The typical noise levels associated with the variousconstruction activit ies and the various construction equipments are present ed inTable 6.20

Noise From ConstructionEquipmentand Operations. Bui lding Equipment and Home Appliances. NJID.300.1. December 31. 1971

Though the noise levels presented for the various construction activit ies far exceedthe permissible standards, it is important to note that the construction noise isgenerally intermittent and depends on the type of operation, location and functionof the equipment. Proper mitigation measures as to regulate the timings ofconstruction, employing noise protection measures etc. need to be worked out.

Occupation Stage:



The noise levels at various locat ions are monitored and the noise levels at the sitewould change due to occupation of the project . There are no sensit ive receptorswith in the immediate vicinity. The noise levels increase due to the project wi l l benegligible in the Project impact area however the project site after occupation mayhave higher noise levels due to human activity, transport etc. However housingareas being enclosed and the compound wal ls also act as barr ier.

Reference Noise Levels:The vehicular noise emission levels s ignif icantly vary with vehicle speed. It istherefore necessary that speed dependency of noise emissions for variouscategories of vehicles is taken into account while using the model for noiseprediction due to the roadway . In this work the speed- noise relations presented byNational Environmental Engineering Research Institute (NEERI) in their report onEnvironmental and Social Assessment Delhi - NOIDA Bridge Project have beenadopted (Table 6.21).

6.11 Energy Consumption& Conservation measuresThe energy efficiency of the layout would depend on a number of factors l ikeorientation, bui lding envelope, building materials, optimization of uti l it ies,meteorology of the location, and surroundings of the building. These factors areconsidered while preparing the layout and optimized to ensure energy eff iciency.The energy requirement for the project shall be met from the public supply ofDISCOM.



The construction project of this scale wil l require energy from the grid of DISCOMfor construction activit ies and subsequent occupation stage. The energyconsumption from the DISCOM during construction act ivity would be l imited pumps,motors and compressors in the order of 50 KVA. While theconsumption/requirement during the occup ation stage is presented in chapter 2.The energy requirement for the project also involves consumption of fuels forconstruction machinery, transport vehicles. The impacts of spil lages and leakages ofthese fuels on soi l are to be mitigated. The energy co nsumption will have additionaldemand on the grid which necessitates additional production of energy. The energyrequirement of Telangana is mainly drawn from the Thermal power, and the powerconsumption reflects in additional pollutant release into atmosp here. Though theimpacts are not local ized in the PIA the impacts can be felt elsewhere necessitatingmitigation/energy conservation measures.

6.11.1 Energy ConservationThe energy efficiency of the units wil l depend on the building envelop, fenestrationand roof quality, ref lecting in transmissivity of the building. The Energy conservationbuilding code for India is yet to be promulgated, and the energy efficiency principlesin vogue should be applied to ensure that the "U" and "R" values are within thelimits. The failure of which may lead to higher consumption of energy, urban heatisland effect. The design guidelines available today in India shall be strict lyimplemented.

Total energy consumption for project per annum us 264.80 lakhs units Table 6.23gives the energy conservat ion measures proposed to be adopted by the proponentsand energy savings anticipated from these measures.

6.12 Impact on Flora & FaunaThere are no migratory corr idors, nesting and Breeding sites within the core zone.No need to take any mitigation measures in this connection. One must be veryconcern towards ecology of the area while altering the habitats. From the l ist off loral and faunal species it is very clear that there are no Rare or Endangered orEndemic or Threatened (REET) species present in core or buffer zone. Some speciesare fall under Schedule I of the Wildlife (Protect ion) Act. Hence there is a need totake mit igation measures in this connection.

The direct impacts: No direct impact on present vegetat ion. No destruction ofbiodiversity within core zone and natural ecosystems through removal of naturalsoils, plants and the f lora l dependent animals. No wildlife population is present inthe study area except the common type of birds and domestic animals. No signif icant



long-term residual impacts on fauna due to project are expected.

Indirect Impacts : No indirect impact on present vegetation. The impact intensitymay be moderate at init ial stage but it might be high when it is in full stretchedoperation condition. The terrestrial habitat is going to be modified as per the greenbelt plan. The proposed activity is not going to affect the local plants, birds, reptilesand amphibians. The producers are grass species, herbs, shrubs and trees. Theconsumers are reptiles, aves and lesser mammals.

16.13.5 Archaeological/Protected Monuments and other Cultural PropertiesThere are no protected monuments or archeological monuments located within300 meters of the proposed site.



16.14 Other social impacts16.14.1 Perceived ImpactsAs revealed during focus group discussions, nearly90% of the respondents are awareof the industrial growth and ongoing construction activity in the area, but less than30% are aware of the proposed project . While they are convinced with the posit iveimpacts of the proposed project, they are not too much concerned about thenegative impacts. In fact, the respondents feel the proposed project has no majornegative impacts to be concerned. The perceptions of the respondents as regardsthe establishment of the proposed project could be summarised as follows:

It would generate sustainable employment to a fairly large number ofskil led and semi-skil led work forces as domestic servants,security guards, clothes washing and pressing, drivers, etc.

Development of the services sector in the area has posit ively contributedto induced development leading to creation of multiplier self and wageemployment opportunities.

It would help further strengthen infrastructure development in the area. The groundwater resources in the area have severely depleted. It may aggravate traffic chaos and pressure on the existing road network.

16.14.2 Predicted ImpactsThe socio-economic impacts of the proposed project could be assessed in terms ofdemand-supply aspects for goods and services in the area, pressure on naturalresources and infrastructure, growth of industry, sustainabil ity of l ivelihoods andemployment.

Some indirect impacts can also be understood in terms of public health and safety,preserving local culture and aesthetics of the archaeological monuments andheritage precincts.

16.14.3 Mitigation of Adverse ImpactsThe management of SMRB wil l be required to init iate the following measuresto minimize the possible negative impacts, as a consequence of developingtheir proposed residential complex project in Kondapur on the surroundingsocio-economic environment:

Install appropriate systems for collection, segregation and safedisposal of domestic waste generated by the residents of the proposedresidential complex.

Install appropriate systems for effective and efficient harvest ing anduse of rain water.

Organise awareness generation programmes for the benefit of theresidents in domestic solid waste management and recycling of thesame.

Raise and maintain avenue plantations in around the project site on acontinual basis.

Volunteer to maintain cleanliness of surrounding areas as part ofSwachh Bharat mission.

16.15 INDUCED IMPACTSThe impacts of the proposed project wi l l not be l imited the direct impact discussedabove. The project would enhance the water quality of the lakes in the watershed,as the rainwater wil l be released into rainwater harvest ing pits. The disposal ofwater in these pits would indirectly help the recharging of t he ground water. Theproject would also help in reducing the erosion of soils due to storm water drainwhich is unplanned at present.

CHAPTER-77.1Risk Assessment and Disaster ManagementConstruction sites in general do not handle toxic and or hazardous chemicalsin large quantit ies, and the usage of the same is temporary for specif ic tasks.However the construction activity has a number of hazards resulting injuriesand fatalit ies, and are not reported widely. The proposed project shal l ensurethe safety of workers and equipment to reduce and mitigate hazards.

Risk and Hazards relating to construction stage will be different fromOccupational stage. Hence the mitigation & avoidance measures would bedifferent at different stage of the project

7.2Hazards &Risks associated with construction activityThe hazards and mitigation measures due to various constructions act ivit iesand hazards to specif ic profession of construction are discussed as follows;7.2.1 Site Access and site conditionsThe construction sites are normally manned by many professions duringconstruction activity. Proper access of people to work place, work placedesign to avoid injuries to people while working due to unevenness of workspace, improper road conditions, and movement of materials poses sitehazards. Similar ly proper rest places for workers d uring lunch breaks, accessto clean drinking water, ventilation in temporary sheds, s ign boards,f irst aidfacil ity, adequate l ighting for work areas, site security by provision of fenceor barricades, arrangements to keep the site t idy and for collection andremoval of wastes are cr it ical to avoid accidents and provide adequateattention to work force during work

7.2.2 Site tidinessAll the construct ion workers shall be briefed about the importance of keepingthe site t idy, by clearing the rubbish and scrap at the end of the day, to keepthe work area clear of equipment and material, by deposit ing the waste in adesignated location, by cleaning up spi l ls of materials.7.2.3 ExcavationExcavat ion for foundation and trenches involves removal of soil and rock.



7-2


Excavat ion or trenching plan shall consider underground services if any. Thehazards related to excavation are face col lapse and injury or burial of workersby soi l and rock, fall and sl ip of people in excavated pits and trenches, andinjury to workers due to fall in g material of equipment. The precautions to betaken are protection of excavation faces by support material, erection ofshoring along trenches Urban areas have building properties adjacent to thedeveloping site, in such cases it is necessary to shore the face of adjacentproperty to avoid fall or collapse of neighboring land or wal l. Vehicularmovement surrounding the excavated area needs to be restricted so as toavoid face col lapse, and possible injury to workers. Excavation areas shall beprovided with adequate l ighting & fensing of excavated trenches

7.2.4 ScaffoldingScaffold is a support ing structure connecting two is more platforms used foreither storage of materials or as a work place. Guard rai ls and toe boards shallbe provided at every place where t he height of scaffolding is more than 2 m.it shall be ensured that scaffold is anchored and tied to the building, it is notoverloaded with men and material it is examined frequently for it strengthand deteoration

7.2.5 LaddersLadders are most commonly used equipment, as it is readily available andinexpensive, and is used widely. However the l imitations of ladders areoverlooked resulting in injuries and fatalit ies. Ladders have l imitations; al lowsonly one person to work, cl imb, and carry materials or work with one hand,restricts movement, should be secured al l the t ime either using ropes or otherpeople. It is essential to secure the ladder before use. The safe use of ladderinvolves; ensuring that there are no overhead power lines, ladder extends atleast one meter above the landing place, never use props to extend the heightof ladder, facing the ladder while cl imbing or descending, making sure footware or ladder user is free of mud and grease, not to over balance or overreach and using a hoist l ine instead of carrying materials.



7-3


7.2.6 Steel erectionSteel erection of building frames requires construction work at heights and inexposed posit ions. However planning at the design stage, setting thesequence of operations, supervising during construction, and usa ge ofpersonal protective equipment l ike safety belts in addition to provision ofsafety nets, anchorage points etc.

7.2.7 Confined spacesConstruction work in confined spaces l ike open manholes, sewers, trenches,pipes, ducts etc. may have dangerous atmosphere due to lack of oxygen ordue to presence of flammable or toxic gases. Work confined space is alwaysconducted under supervision, with adequate safety measures l ike; checkingthe atmosphere in confined space before entry, provision of rescue harnessto everyone, involvement of minimum of two persons - one person formonitoring and ready for rescuing if needed, provision of safety equipmentlike atmospheric testing device, safety harness, torch l ight, f irst aidequipment, f irefighting apparatus, and resuscitation equipment.

7.2.8 VehiclesThe construction area shall have multiples of vehicles moving material withinthe site and from outside the site. The most common causes of onsite traff icincidents are; bad driving technique, carelessness, carrying unauthorizedpassengers, poor maintenance of vehicles, site congestion, overloading anduneven ground and debris. It is proposed to ensure that all dr ivers haveappropriate driving l icense, routes are planned, marked and leveled, enlist ingadditional workers during reversing, switching off the engine during idling,and periodic maintenance schedule for all vehicles.

7.2.9 Movement of materials -Cranes and HoistsCranes and hoists are used for movement of materials within the site. Theoperators of these machines are qualif ied and the cabins wil l have a signalchart to understand the signals given by site workers. The site workers aretrained in signals for transmitting to the operators of these machines.



7-4


Stabil ity of these machines and overloading are major concerns whileoperating these machines hence it is necessary to avoid overloading, and toensure structural stabil ity of these machines before use. The cranes wil l havesafety hooks, and the workers are trained in using the same, and crit ically ofthe hook. In case of hoists, it wi l l be ensured that a gate is provided at eachplatform, travel of passengers is avoided, and platforms are always alignedwith landing points.

7.2.10 Lifting and CarryingConstruction work involves a lot of manual labour resulting in stress andinjury to the workers. It is proposed to provide wheel burrows, trol leys etc. ,to avoid manual carrying of materials. In situations where manual l ift ing ofmaterials is needed, the workers are trained in safety related to correct l ift ingtechnique, throwing technique in addition to provision of personal protectiveequipment.

7.3 Working EnvironmentMany chemical substances l ike adhesives, cleaning agents, f loor treatments,fungicides cements, grouts, insulants, sealants, paints, solvents, etc. solventsare crit ical substances which require due attention as they are f lammable andor toxic in few cases. The usage of these chemical substances is alwaysensured to follow the instruct ions mentioned by the manufacturers. Solventswil l not be used for removal of paints and grease from skin. Personalprotective equipment is provided by the proponent and or the contractor andthe site safety executive shall ensure the same. Construction sites are alsomajor sources of noise resulting in hearing impairment. Hence it wi l l b eensured that all emission sources are provided with mufflers or si lencers,motors are covered, machinery panels are secured and are not allowed torattle, and noise attenuating screens are provided to segregate noisy workingareas, in addit ion to provision of personal protect ive equipment. Gloves areused when using Vibration causing equipment. Adequate l ighting is providedin work areas to mit igate hazards.



7-5


7.4 Health Hazards on Construction SitesConstruction works involve various trades with variable times of operation.Construction operations have a number of potential hazardous operations andresulting in health hazards to workers. Exposure differs from trade to trade,from job to job, by the day, even by the hour. Exposure to any one hazard istypically intermittent and of short duration but is l ikely to reoccur. A workermay not only encounter hazards related to his profession, but also encountershazards related to other professions in the vicinity. This pattern of exposureis a consequence of having many employers with jobs of relatively shortduration and working alongside workers in other trades that generate otherhazards. The hazard severity is contingent on concentration and duration ofexposure in a specif ic construction work. A l ist of hazards present for workersin various trades is presented in table 7.1

7.5Mitigation measures and controls7.5.1 Engineering controlsHazards originate at a source. The most eff icient way to protect workers fromhazards it to change the primary source with some sort of engineering change.For example, a less hazardous substance can be substituted for one that ismore hazardous. Water can be substituted for organic solvents in paints.Similarly, non-si l ica abrasives can replace sand in abrasive blasting (alsoknown as sand blasting). Or a process can be fundamentally changed, such asby replacing pneumatic hammers with impact hammers that generate lessnoise and vibration. If sawing or dril l ing generates harmful dusts, particulatematter or noise, these processes could be done by shear cutting or punching.Technological improvements are reducing the risks of some musculoskeletaland other health problems. Many of the changes are straightforward -forexample, a two-handed screwdriver with a longer handle increases torque onthe object and reduces stress on the wrists.

7.5.2 Environmental controlsEnvironmental controls are used to remove a hazardous substance from theenvironment, if the substance is airborne, or to shield the source, if it is aphysical hazard. Provision of f lexible Local exhaust ventilation (LEV) may beused. The simple and effective method for control l ing exposure to radiantphysical hazards (noise, ultraviolet (UV) radiation from arc welding, infraredradiant ( IR) heat from hot objects) is to shield them with some appropriatematerial . Plywood sheets shield IR and UV radiation, and material that absorbsand reflects sound wil l provide some protection from noise sources. Majorsources of heat stress are weather and hard physical labour. Adverse effectsfrom heat stress can be avoided through reductions in the workload, provisionof water and adequate breaks in the shade and, possibly, night work.

7.5.3 Personal protectionWhen engineering controls or changes in work practices do not adequatelyprotect workers, workers may need to use personal protective equipment



7-8


(PPE). In order for such equipment to be effective, workers must=t be trainedin its use, and the equipment must f it properly and inspected and maintained.Furthermore, if others who are in the vicinity may be exposed to the hazard,they should either be protected or prevented from entering the area.

7.6Fire Hazards & Fire Protection systems in High Raise buildingsThe most crit ical r isk in high rise buildings is f ire related risks. In view of thisbuilding norms prescribes f ire protect ion faci l it ies and firefighting facil it iesas mandatory requirements.

CHAPTER-88.1ENVIRONMENT MANAGEMENT PLANThis chapter outl ines the Environmental Management Plan for the project, budgetprovisions, institutional arrangements for implementation and monitoring of theEMP and Post monitoring of the project

8.2THE PROJECT LOCATIONThe project is envisaged to to develop a residential project at Sy. No.311,312,313,316 & 317 situated at Bachupally(V), Quthbullapur (M), Ranga Reddy(D), Telangana. The project would cater to various market demands and needs ofthe people. The project si te is surrounded by exist ing residential colony by nameReddy Colony, Prajay Shel lters and Swarnapuri on South, and vacant land ofneighbours on Nothern and Western directions.

The Site is connected to Old Mumbai Highway by Miyyapur – Bachupally (12 MetersRoad expanding 45 m) in the Eastern side at a distance of 2 KM. The site is adjacentto Cooco cola Road which is currently 9 Meters Road but expanding to 30 MetersRoad.

8.3MAJOR FINDINGS OF THE EIAAn EIA was conducted as per the broader guidelines of TOR issued to the project andthe major f indings of the EIA study are presented below

8.4Environmental Impacts8.4.1 Impact on Physical ResourcesConstruction of proposed project requires huge qu antit ies of natural resources l ikesand, sub grade and aggregate, and materials produced from natural resources l ikebricks, cement and steel. The material shall be drawn from local sources and thelead distances range from 1- 250 km. The impacts on physical resources of sand willbe irreversible while bricks wil l be brought from kilns which use Coal ash. Thematerial requirement of steel, cement etc. wil l be purchased from manufacturerswith in state. Hence, no major impacts on physical resources as regards the



8-2


avai labil ity and procurement of construction material are anticipated due to theproject .

8.4.2 Impacts on Air QualityImpacts on air quality during construction stage are l ikely to be due to operation ofconstruction yards, material transport on trucks and fugitive emissions from theconstruction sites. The model results for occupation stage show slight increase inthe air qual ity and in worst concentrat ions are fall ing within the site, and the resultsare with in the prescribed l imits. Mitigation measu res required for offsetting the airquality impacts are presented in the table 8.1 Environment Management and ActionPlan.

8.4.3 Impacts on Noise QualityImpacts on noise quality during construction stage wil l be signif icant. Hence theconstruction near the hab itation is proposed only during daytime. The impactsduring occupation stage will be on the plots near to the main entrance. Constructionworkers wil l be provided with protection equipment to guard against the noiseimpacts. Noise mit igating measures wil l be suggested for construction equipmentand DG sets.

8.4.4 Impact on FloraThe project site and its surroundings do not form a habitat to any endangered flora.There are very few trees within the project site due to anthropogenic pressures. Theproject wil l enhance the aesthetics of the site due to the provision of avenueplantation and central greening. This would ensure minimum impact on f lora.

8.4.5 Impact on FaunaAs there are no endangered species of wild l ife in and around the project site, i t isl ikely to have minimal impact. The avifauna will f ind abode o n the trees proposedto be planted. This would enhance the aesthetics of the area. Pet animal faecesshould not enter the storm water drains.



8-3


8.4.6 Impact on Land useThere is no land acquisit ion for this proje ct. The land use of the site fallow land andclassif ied as residential by HMDA. However the topography of the land beingrocky plains involves cut and f i l l operation. Erosion and sedimentation areimpacts anticipated during construct ion. Mitigation measures shall be adopted toavoid the same. The area development would increase the housing activity in thesurroundings, which is a posit ive impact, as barren lands wil l be used for productiveusage, and the negative impacts wi l l be pressure on the infrastructure faci l it ies .

8.4.7 Impact on Surface Water ResourcesThe degradation of water quality can occur during construction phase fromincreased sediment load into watercourses near the construction site. Suitablemitigation measures proposed, as part of the EMP will ensure that the residualimpacts are minimal. Storm water runoff would increase due to the increase inimpervious surface, and rainwater harvesting structures wil l be provided asmitigation measure. The design of the storm water drain wil l co nsider the additionalrunoff. The urban storm water joining the storm water drains may carry pollutantsfrom impervious surfaces.

8.4.8 Impact on Ground Water ResourcesGround water shal l be drawn during construction, and will be used to augment themunicipal supply during non -monsoon season if necessary. Exploitat ion of groundwater wil l have an impact and the same shall be restr icted to ensure resourceconservation. This impact wil l be marginal, as the ground wa ter wil l not be drawncontinuously.

8.4.9 Impact on InfrastructureThe infrastructure of communication avai lable at present is saturated; the proposalto lay new connectors between HMDA, GHMC wil l reduce the congestion. Thedevelopment in combination with this project activity wil l have marginal impact.The additional requirement of power would increase the pressure on the electricalinfrastructure and requires additional power generation in the overal l context



8-4


8.4.10 Impact on Human Use ValuesThe dominant land use in the area is residential , and expected commercial spacewil l increase the pressure on the residential local it ies. There is no additionalrequirement and or acquisit ion of land. The provision of public lung space in theproject and other community facil it ies wil l reduce the additional tra nsportrequired avai l ing the facil it ies. The project authorit ies wil l provide road safetymeasures to reduce r isk of accidents in the internal roads. The impact on Human usevalues is marginal .

8.5 ENVIRONMENT MANAGEMENT MEASURES PROPOSEDA description of the various management measures during the various stages of theproject is provided in the following sections.

8.5.1 Pre-construction stageDuring the design and preconstruction stage the management proposes to complywith the regulations of town planning, explore the availabil ity of sufficientresources, provide plantation and sink bore wel ls after obtaining the necessarypermission.

8.5.2 Construction stageThis wil l be the most crucial and active stage for the Environment Management Plan.In addition to the monitoring of the construction activity itself to the pol lutionlevels within permissible l imits, mit igation and enhancement measures for waterresources wil l go on simultaneously as the construction progresses. To facil itateimplementation of the enhancement and mitigation measures suggested workingdrawings of the same would be prepared after completion of detailed project report .In addition, the need for a balanced evaluation and planning for risks associatedwith construction activit ies related to housing and commercial project wil l be partof the Supervising Contractors responsibil ity.

The resource conservation by way of identif ication of materials and construction



8-5


debris recycle/disposal wi l l be formulated by the supervising consultants. Theresponsibi l ity of environment management plan l ies with the project authorit iesthat would implement the plan in consultation with other consultants, by includingappropriate provisions in the contract/sub contract documents and providing thenecessary facil it ies .

8.5.3 Operation stageThe environment management plan wil l be implemented by ownersassociations/societies, where project authorit ies are co - opted as members, andwhile the management plan related to the util it ies l ike roads, street l ighting andcommon open spaces l ies with the Seril ingampally Municipality. The management inoperation stage will essentially entai l maintenance of sewage treatmentplant, maintenance of uti l it ies, and monitoring activity in the project site.Monitoring for pollutants specif ied in the Monitoring Plan wil l serve the twopurposes. In addition to checking the efficacy of theprotection/mitigation/enhancement measures implemented, this wi l l help verify orrefute the predictions made as a part of the impact assessment. Thus, it wil lcomplete a very important feedback loop for the project.

The measures adopted and/or to be adopted during different stages of the projecthave been detailed in table 8.1.

8.10 REPORTING SYSTEMReporting system provides the necessary feedback for project management toensure qual ity of the works and that the program is on schedule. The rationale fora reporting system is based on accountabil ity to ensure the measures proposed aspart of the Environment Management Plan get implemented in the project.

The reporting system will operate l inearly with the contractor who is at the lowestrung of the implementation system reporting to the Supervision Consultant, who inturn shall report to the Pacif ica India Projects PVT Ltd during construction stage andto society during occupation stage

8.11 ENVIRONMENTAL MANAGEMENT BUDGETThe environmental budget for the various environmental management measuresproposed in the EMP is detailed in table 8.6 there are several other environmentalissues that have been addressed as part of good engineering practices, the costs forwhich has been accounted for in the Engineering Costs. Moreover, sinceenvironmental enhancements have not been finalized at this stage, the tableprojects the typical costs aspects wise and the detailed cost estimate is presentedin Annexure A.

8.12 Green belt PlanConstruction activit ies change the natural environment. But it also creates a builtenvironment for the surrounding. The project requires the implementation offollowing choices exclusively or in combination.8.12.1 Construction Phase

Restriction of construction activit ies to defined project areas, which areecologically less sensit ive.

Restrictions on locat ion of labour camps and offices for project staff nearthe project area to avoid human induced secondary additi onal impacts onthe f lora and fauna species.

Cutting, uprooting, coppicing of trees or small trees present in and aroundthe project s ite for cooking, burning or heating purposes by the laborerswil l be prohibited and suitable alternat ives for this purpose wil l be found.

Along the major construction work the peripheral greenbelt should bedeveloped, so that; i t wil l grow to become a full -f ledged green cover by the

t ime the construction is over.8.12.1 Operation PhaseEnhancement of current ecology at the p roposed project site wil l entai l thefollowing measures: Plantation & landscaping Park & avenue plantation Green Belt DevelopmentPlantation & landscapingSelection of the plant species wil l be based on their adaptabil ity to the existinggeographical conditions and the vegetat ion composition of the forest type of theregion.During the development of the green belt within the project area, it has to beemphasized that those native plant species should be planted which are having goodornamental values and fast growing with excellent canopy cover.Avenue PlantationParks or gardens maintained for recreational and ornamental purposes wil l not onlyimprove the current ecology of the proposed site but also aesthetic value in thearea. The plan for plantation in parks and avenues is given below.Parks/Gardens

Ornamental trees with spreading branches, shade giving withcolorful f lowers for people to relax.

Suitable patches of lawns, rocketry with cactus and other small f loweringxerophytic plants.

Avenue plantation Trees with colonial canopy with attractive f lowering Trees with branching at 10 feet and above Trees with medium spreading branches to avoid obstruction to the traffic Fruit trees to be avoided because children may obstruct traff ic and general

movement of public.

Greenbelt DevelopmentGreen belt is recommended as one of the major components of EnvironmentalManagement Plan. Out of the total area, green belt is developed in 4898 sq.mts.



8-32


Proper attention and management is required to maintain the survival rate of theplanted species. Around 23 plant species suggested under the green belt plan andaround 30 lakhs f inancial budget is proposed to develop the habitat. Species suchas Roystoniaregia (Royal palm), Caryotaurens (Fish tail palm), Polyalthi alongifol ia,Coll istemonlinearis (Bottle brush), and Plumariarubracan be raised in large numberin all the directions. Species such as Ficusbenghalensis, Ficusreligiosa,Ficusglomerata, Phyllanthusemblica, Pterocarpussantal inus, Anonasquamosa,Bauhinia recemosa can be raised in buffer areas. Small herbs, ornamental speciesand common flowering plants as per the availabil ity can also be raised near thepaths and corr idors of the existing plants.

Selection of plant species for Green belt developmentThe selection of plant species for the development depends on various factors suchas cl imate, elevation and soil. The l ist of plant species, which can be suitablyplanted, and having signif icant importance are provided in Table 8.4 The plantsshould exhibit the following desirable characteristic in order to be selected forplantation.

i. The species should be fast growing and providing optimumpenetrabil ity.

ii. The species should be wind-firm and deep rooted.iii. The species should form a dense canopy.iv. As far as possible, the species should be indigenous and locally availablev. Species tolerance to air pollutants l ike SPM, SO2 and NOx should be

preferred.vi. The species should be permeable to help create air turbulence and mixing

within the belt.vii. There should be no large gaps for the air to spil l through.viii. Trees with high foliage density, leaves with larger leaf area and hairy on

both the surfaces.ix. Ability to withstand conditions l ike inundation and drought.x. Soil improving plants (Nitrogen fixing, rapidly decomposable leaf l itter).xi. Attractive appearance with good flowering and fruit bearing.
