Transportation Plannlng and Environment Division

February, 2007

The Environmental impact Assessment (EIA) study flndlngs/results and other

related information furnlshed in this report are based on the primary data

collected for the baseline environmental studies carried out by the Central

Road Research Institute (CRRI) New Delhl, as well as from the secondary

data available from various other agencies (Government and Non - Government). The responsibility of the CRRI Is limited to the output produced

for the Environmental Impact Assessment study for the proposed Metro

Bhawan, located in the Fire Brigade Lane, Connaught Place, as per the

objectives of the EIA study and Terms of Reference (TOR) of the work order.

Any use of the flndlngs of the report without consulting CRRI by any other

agency or person other than the client is solely at thelrfown risk and

responsibility.

?he construction and operation of any commercial or offlce bulldlng/ complex In any urban area, particularly in the metropolitan cltles like Delhl have significant impacts on the surrounding envlronment because of the likely increase in demand of potable water supply and sewage dlsposal requirement of an already over-stressed system of the area, Further, air quallty degradation and nolse pollution may further worsen due to increased vehlcular tramc on the adjacent road network along with the traffic congestion and posslble Increased incldenb on road. Thus, In view of possible associated adverse environmental Impacts, Mlnistry of Environment and Forests (MoEFI Govt. of Indla, has made it mandatory to carry out Environmental Impact Assessment (EIA) study for various building and construction projects wlth built-up area between 20,000 mZ -1,50,000m2 . With a vlew to assesslng potential environmental Impacts arlslng out of the construction and operation of the Metro Bhawan building (built-up area 26,000 m2), the DMRC had retalned Central Road Research Insmute (CRRI), New Delhi to undertake EIA study for varlous environmental components and to prepare a detailed Environmental Management Plan (EMP) for the same.

The Metro Bhawan located at the Connaught Place (Central Buslness DlstrlQ) in the New Delhl District wlll be the main Operational Control Centre (OCC) for the entire Metro network of Delhl controlling its operation and maintenance.

J Thls EIA report contalns baseline data on alr quallty, noise levels, vehlcular

I traffic 81 parking, water quality, soil characteristics and green cover

,J components at the project slte wlth a vlew to identifylng and assesslng the potential Impacts during different phases of project actlvlties. An

I Environmental Management Plan has also been delineated for the mltlgation of the adverse impacts.

Chapter I Introduction

All wnstructlon - based projects must co-exlst satisfactorily wlth its surroundlng

envlronment, so as to reduce the envlronmental Impact caused due to varlous

actlvltles related to its constructlon and subsequent operation. Hence, a sound and

safe envlmnment management plan Is requlred to be Incorporated by the project

proponent to achieve sustalnable development. In order to assess the llkely impacts

arlslng out of the constructlon of Metro Bhawan on the surroundlng environment

and evaluating means of allevlatlng the llkely negatlve Impacts (If any), emanating

from thls project, the Delhl Metro Rall Corporatlon (DMRC) LM. has retalned Central

Road Research Institute (CRRI), New Delhl as thelr envimnmental consultant. The

CRW had carried out an Environmental Impact Assessment (EIA) of Metro Bhawan

bullt at Flre Brigade Lane, Barakharnba Road, New Delhl, for varlous environmental

components, whlch am llkely to be affected due to the proposed actlvlty.

The Metro Bhawan shall be the maln Operational Control Centre for the smooth

funalonlng of DMRC related work. Thls bullding has been bullt in en area of 10,870

mZ. comprising of two basements and eight floors. The total cost Incurred in thls

project is approximately 4189 lakhs. A brlef summary of the project Is provided In

the Chapter 2 - Project Ssttlnu. Any bulldlng of thls magnitude Is bound to put \ >

pressure on publlc utilities, water avallabillty and at tlmes contrlbutlng to trafflc G . segment, besldes sometlmes involving resettlement and rehabllltatlon issues hence

I ? assessment of impacts arislng out of such actlvlty Is mandatory. , ,

The DMRC Culture specifies that the Metro and its related constructlon actlvkles

should not lead to any ewloglcal or cnvlronmental degradation. Thereby,

Envlronrnental Impact Assessments are done for every sectlon of the Metro to

ensure that the ecological balance Is not disturbed by Metro constructlon actlvltles.

This Is further established by the fact that the Delhl Metro Rail Corporatlon (DMRC)

has already acquired the I S 0 14001 certlfieate for establishing an environmental

management system maklng It the First Metro in the World to recelve thls

certlflcatlon at the constructlon stage of the Metro. In addltlon, the Delhi Metro has

3.1 Qanerml Environment 3.1.1 Cllmakr

The climate of the Delhi region Is sernl-arid type, with three well-defined seasons.

The cold season beglns at the end of November, and extends to early July and

contlnues up to September. The hot summer extends from the end of March to the

end of June. Further, the cllmate of NCT Delhl is influenced by its Inland posltlon

and prevalence of alr of the continental type durlng the major part of the year.

Extreme dryness with the Intensely hot summer and cold winter am the

characteristla of the cllmate. Thus, year can be divided into four seasons as given

below:

3.3 Geological Settlnp of Delhl

Delhi, the capital of India is bounded by the Indo-Gangetic alluvial plains in the

North and East, by Thar Desert in the West and by Aravalli Hill ranges in the South.

The terrain of Delhi is flat in general except for NNE-SSW trendlng ridge, which is

considered an extension of the Aravalll hills of Rajasthan. The ridge may be said to

enter Delhi from the SW. The eastern part of the ridge extends up to Okhla in the

South and disappears below Yamuna alluvium in the NE on the right bank of the

river. River Yamuna enters Delhl from the North and flows Southward with an

Eastern bends near Okhla. The exposed rocks of Delhl are mainly quartzites with

moderate folding. What is of interest in seismic hazard estimation is the depth of

sediments over the rock layers. However, varlous recent earthquake events felt in

and around Delhi recorded by various observations located in varlous parts Delhi

are listed below. Since 1994, there has been a marked cessation of seismic activity.

Final Report ad gf Metro Bhawan, mrakhamba Lane, Canneupht uacn

It is shown that the stresses, which earller were being released periodlcally, are

now stored h rocks llke a spring. I f the trend continues then one day these stresses

will be released resulting in an earthquake.

3.4 Ground Water Situation in the Study Area

Groundwater is one of the major sources for water supply in many parts of the

country. In Delhi too, ground water contributes to substantial quantity of supply.

The groundwater is largely being utlilsed as a drinklng water resource, especially in

new development areas mainly because of the Insufficiency of the Yamuna water

share for Delhl. Faster withdrawal rates have lead to fall in water table and flnally

depletion of ground water. The groundwater recharge areas need to be Identified so

that maximum recharge can be achieved. The recharge areas needs to conserved

and preserved for the sustainable management of groundwater and to maintaln the

potentlal of the groundwater In Delhi. According to the Central Ground Water Board

(Annaxure X I ) the recharge areas identlfled is the northern most part of the city.

Areas where the ponds already exist in the villages, the Najafgarh jheel and its

surroundings and the region between the Northern Ridge can also be used as water

recharge area. A cornparlson of water levels from 1962 to 1977, 1977 to 1983 and

1983 to 1995 brlngs out a clear picture of water level declines in major parts of the

territory. The water levels and fluctuations during these perlods are given in

drawing. During 1977, the water table was by and large within 6m below ground

level (bgi) in major parts of the territory deepest being 23m bgl at near Qutub

Minar In Mehrauli Block. In 1983, the depth to water level declined to 10 m bgl in

major parts with the deepest level being 26m bgi at Mehrauli In Mehrauii Block. I n

1995 the extent of area with water levels in the range of 10 to 20m bgl has

substantially increased and the deepest water level is about 35 m bgl at Gadaipur in

Chattarpur basin of Mehrauil block.

Fig. 3.5: OrO~nd Wmm Quality In Dslhl (2002) 3.5 Geography of the Projact Slta The proposed study area comas under the jurlsdlction of New Delhl Munlclpal

Corporation (NDMC). The area Is plaln and devoid of rocky outcrops and Is not

covered by any notlfled forests. The project site is well connected by road and rall.

The nearest rallway station Is situated at New Delhl Railway Statlon wlthln a radlus

of 3 km. The nearest metro statlon is situated at Bardkhamba road itself (Une 3).

The project slte Is located In the New Delhl Dlstrlct, which is located centrally in

the state wlth varled surface altitude due to Delhl Rldge. Nearly 10 sq. km area falls

wlthln rldge area whlch possesses 225 to 255 m helght above mean sea level

(amsl). The surface is sloplng gradually towards east upto Yamuna rlver course

where the altitude Is 210 amsl (above mean sea level). The total area of New Delhl

Distrlct Is 35 sq. km. The top sol1 zone is predominantly consisted by sllty-clay

material followed by thin partlngs of clay-sllt, sandy-silt and clay layers

alternatively. Sandy-sllt strata behave as favourable aqulfer zone In order to get a

substantlal dlscharge. In the western part of this district covering an area of

Rashtrapati Bhawan, Chankyapuri, Shantlpath, South & North Avenue and

Connaught Place, tubewells are tapplng both prevalllng formation i.e, alluvium as

well as hard rock. Whereas, in the eastern part only aquifers of alluvium are tapped

whlch are glving yleld of ZOO - 500 i/mln. The extreme eastern part of thls dlstrict

is bounded by Rlver Yamuna where a domain of Yamuna flood plaln exlsts in a

llnear fashion along river Yamuna. The potentiality of groundwater in thls formation

is relatlveiy high ranging from 500 - 1600 l/min. Groundwater in thls area occurs

both under water table as well as under sernl - conflned condltlons in the alluvium.

The depth to water level in the dlstrlct ranges from 5 - 25 m below ground level,

the wlde varlatlon occurs due to wlde range of topographic relief. Right from the

Yamuna Flood Plain where DWTL ranges from 5 - 8 m to Delhl ridge where DTWL

ranges from 10 - 25 m are the wlde-ranging level occurs in the district. The tube

wells usually tap Kankar zone admixed wlth clayey sllt and sandy-sllt aquifer zone.

These aquifer zones are generally encountered altematlvely MOW the depth of 20

mbgl (meters below ground level) and onward up to the basement rock.

In alluvial formations, the quality of groundwater deterlorates with depth, which Is

variable in different areas. The groundwater Is fresh at all depths in the areas

around the ridge falling in Central, New Delhi, South and Eastern part of South-

west (ridge) districts and also Chattarpur basins. The concept of hydro-chemlcal

facles can be used to denote the diagnostic chemical characteristics of water in

hydrological systems. The chemical quality of ground water in NCT Delhl varies with

depth and space.

history of Delhi reglon lndlcates falrly high Selsmlclty for the city of Delhi. The most

actlve area of the region is conslded to be the trl-junction of the Delhl-Hardwar

rldge, Lahore-Delhl ridge and axis of Delhl folding. Most d shocks are Interpreted to

be shallow focus and have concentrated around Sonepat, Rohtak and Gurgaon

region In and around Delhl may be considered as selsmlcally very actlve and the

tectonic elements of the area are consldered capable of generating an earthquake

of magnltude 7.0 on Richter Scale. Some areas of Delhl, due to thelr unique

subsurface settlngs, are relatively more prone to damage In ease of such

eventualities. In such cases, apart from the denslty of population and type and

Chapter 4 Baseline Data

4.1 Qaneral Experlence over the years from all over the world Including Indla, has shown that

the Environmental Impact Assessment (EIA) studles are always conducted under

severe llmltatlons of tlme, manpower, flnanclal resources and data. These

requirements for EIA could be greatly reduced by focusing the EIA study on a

llmlted number of relevant issues rather than an elaborate llsting of values of all

envlronmental parameters. This could be achleved through lnwrporatlon of a

method for identlflcatlon of slgnlflcant issues as a component of EIA. Scoplng is a

process of identifying slgnlflcant issues to be considered for an EIA. Essentially, it Is

a procedure design to establish the Terms of Reference (TOR). For Identlwlng the

Important parameters to be Included In the EIA of the proposed Metm Bhawan

project, an Informal meetlng of the Sclentlsts of the Central Road Research Instltute

(CRRI) wlth the Delhl Metro Rail Corporatlon (DMRC) was done. Based upon the

dlscusslon wlth DMRC offlclals, TOR lncludlng Objectives and Scope of the EIA study

was agreed upon (as described In Chapter 1).

4.2 Impact checkllst There are several methodologies for ldentifiwtlon of Impacts vlz., Ad-hoc

procedure, and Overlay technique, Checklist, Leopold Matrix and Networks. In the

present study, the chackllst methods has been preferred over the other methods

because of their slmpliclty in understandlng as they do not provide or requlm

guldellnes regarding the methodology for data eolledlon and lnterpretatlon. Thus,

Checklists present a speclflc list of envlronrnental parameters to be lnvestlgated for

possible Impam and do not require establishing direct cause - effect llnks to various project actlvltles. The checklists can be augmented by instructions on how

to present and make use of data and by the lncluslon of explicit crlterla for Impacts

of certaln magnltude and Importance. The checkllst, In general, Is used to ldentlfy

and subsequently to evaluate the magnitude and Importance of the potentlal

Impacts. It is important to recognize that at thls stage of Impact assessment, the

concern Is potentlal Impact, as opposed to the residual lmpact whlch could be

expected if mltlgation measures were to be adopted and were effective in

Final Report EM of Mktm Bhawm, Bsrakhem&a lane, Connaught Ham

mlnimlslng the Impact. In effect, this can be thought of as presentatlon of worst

case seenarlo as far as envlronmental matters are concerned. In the checklist, the

Impacts are assoclated with three phases of the project (Design and Pre-

construction., Construction and Operation phase) are subdlvlded In relation to the

principle actlvitles taking place In each phase. Thls form of presentatlon is slmpler

than the alternative of subdivlslon In relation to the envlronmental component or

value whlch is effected, slnce a slngle actlvlty may affect the several components

and values. Thls approach focuses attention on the effects of an adlon and is less

likely to result In impacts belng overlooked.

A check llst applleable for various construalon projects, whlch may not be dlrectlv

applicable for building projects have been taken as a flrst approxlmatlon (Table

4.1). Based on the check list and through literature search, site vlslts and

dlscusslon with the DMRC officials regarding their past experience of EIA projects of

slmllar nature, a detailed methodology for varlous fleld studles for collecClon of the

base llne data were planned and is descrlbed in the following section. In the present

case, the baseline data at the project slte, relevant to the proposed metro Bhawan

Project were identlfled and prlmary surveys carrled out for the detalled basellne

data collection through fleld studies;

different sources (Annexurn - 11).

4.3.3 Groundwater Quality Monitoring

The groundwater table was encountered at depths varying from 9.40 m to

11.50 m below the existing ground level at the locations of bore holes BH-1

to BH-4 and BH-6 to BH-8, It may rise up during heavy rains/ rainy season

or go down during dry season. The result of the groundwater analysis

undertaken is given below (Table 4.6). The results shows that the

graoundwater quality meets the drinking water quality standards specified

under IS 10500-1983 (Annexure V and Annexure VI)

Rnal Report PIA of Mstm Bhswan, Bamkhamlnr Lana. Conneught Wace

No significant land disturbance ilke eroslon, subsidence & instability Is anticipated

at this site. The Metro Bhawan is situated In Delhl region whlch comes under

Seismic Zone IV, hence all the precautionary measures has been taken in

accordance with Natlonal Building Code (2005) to safeguard the same against

earthquake.

4.3.9 Trafflc Study

As part of study, traffic surveys were carried out to assess the impact generated by

trafflc of Metro Bhawan on the surrounding road network. A classlfled Trafflc

Volume Survey was carried out on a normal working day for 16 hours duration, The

survey was carried out on all three approach reads vlz. Bengall Market road

connecting Metro Bhawan wlth Maharaja Ranjit Slngh Marg road, Mayur Bhawan

approach road connecting Metro Bhawan with Connaught circle and Shlvaji Bridge

Railway Station and topai Dass Tower approach road connecting Metro Bhawan

with Barakhamba road. Trafflc volume counts were also carrled out on the other

smaller links such as Barakhamba lane and approach road from Bengali market

approach road to FCI building on the other side of Metro Bhawan. Classlfled trafflc

turning movement survey was carried out at Y-intersection of Bengali market - Gopal Dass Tower and Mayur Bhawan approach roads in front of Metro Bhawan

along wlth padestrlan surveys as there is appreciable pedestrian movement

between Shivafi Bridge Railway Station and Gopal Das Tower / Barakhamba

approach road. Counts of each turning movement of each class of vehlde vlz. ears, two wheelers, auto rickshaw, cycles, cycle-rickhaw bus, mini bus, trucks, LCVs and

other vehicles along with pedestrian count were taken for every 15 minute intervals

during the period of survey on pre-designed proforma through trained enumerators.

The 15-minute traffic and pedestrian data for each turning movement and each

class of vehicle were fed into Computers In Excel spread sheets for analysis (Tablo

4.9). Hourly-classified trafflc turning movements at all the approach roads were

calculated and added to get daily trafnc along various direction on the surrounding

road network. Hourly variation of total trafflc and its composition at the Intersection

in front of Metro Bhawan is shown in Flg. 4.liand Fig. 4.12 Trafflc flow diagram

From the analysts of trafnc and characteristics of surrounding road network,

followlng concluslons can be made:

(I) Metro Bhawan is connected with main road network of Delhl through three

approach road vlz Babar road in the east, connectlng Maharaja Ranjlt Slngh

Marg and Bengali Market. Mayur Bhawan approach road in the north-west

connecting Connaught Circle and Gopal Dass Tower Road In the South

connectinp Barakhamba Road

(ii) All the approach roads are relatively narrow conslstlng of three lane undivided dual carriageway excepting smaller stretches of divlded carrlageways near

Gopal Dass Tower and Metro Bhawan.

(ill) All the approach roads am carrying appreciable traffic volume because of

surrounding built up area.

(iv) The intersection In front Is catering to daily (16 hrs) trafflc volume of about

15,500 vehlcles wlth two district morning (9.00 to 10.00 am) and evenlng

(5.00 pm - 6.00 pm) peak hours.

(v) Cars constitute major share of trafflc (48%) followed by two wheelers (26%)

and auto rickshaw (21%) of the total trafflc.

(vi) There lo high pedestrian trafflc movement to the tune of 15,000 pedestrians

per day (16 hrs) along Gopal Das Tower - Shivaji Brldge approach mads at the

lntersectlon In front of Metro Bhawan.

(vll) Babar/ Bengali Market approach road Is catering to dally trafflc volume of

about 13,000 vehlcle, while Mayur Bhawan approach road is caterlng to 11,500

and Gopal Das Tower approach road about 7,500 vehicles.

(vi1l)There wlll be nomlnal effect of trafflc generated by Metro Bhawan on the

surrounding road network.

(ix) There is enough reserve capacity on all the approach roads to Metro Bhawan

to cater to future growth of tfafflc and trafflc generated by Metro Bhawan.

(x) The Intersection in front of Metro Bhawan is catering to hlgh traffic volume and

hence needs to be re-deslgned and signallzed in order to cater to the future

trafFlc.

(xi) The entry and exlt gates of Metro Bhawan should be located on dlfferent

approach roads 75m away from Y-intersaction in order to avold congestion at

the intersection.

5.3 Impaets due to Project Loeatlon/Deslgn

5.3.1 Dlsplacarnsnt of People

Slnce the project and its associated actlvltias are limited to acquired and approved

area of 10870 m2 and is free from encroachment, hence no dlspiacernent of any

person was antleipated. Prlor to the construction of Metro Bhawan, four old CPWD

bulldings along with thelr servants existed in the same slte and were completely

demolished before construction.

The proposed project Is being constructed In the Lutyen's Delhl under the

jurlsdictlon of NDMC. Thereby, the approval of Delhl Urban Art Cornmlsslon (DUAC)

was also mandatory and hence duly taken by DMRC for the present bullding. The

development in the entlre project area was as per the approved master plan

(Master Plan 2001) of Delhl Development Authority (DDA), hence no landuse

change has been anticipated. The pmject Site also forms part of the said master

plan and deslgnated for commercial purpose.

The proposed site Is an open land earmarked for construction of commerclai Iofflce

complex and possessed 124 trees of different ages (Table 4.10.). Thereby, the

approval for flnaliy cutting of 58 trees was taken from the designated "Tree

OfFlcer". Slnca, the entlre activltles related to project shall be confined to the

deslgnated slte, hence no cutting of trees beyond the project site was undertaken/

carried out.

5.3.4 ShlRlnp of Utilities

A few offlce bulldings previously bullt had to be removed to facllltate the

construction of metro building. Necessary permission/ Information were obtalned

from concerned agencies (electrldty, water supply, munlclpallFy atc.) befor@ the

actual dernolltion of buildings. Hence, except these dernolltlons, the project adlvlty

dld not involve any further shlftlng of existlng utiiitles such as water supply

plpellnes, sewers, OFCs, electrical lines, etc. due to the proposed project.

Surface and ground water resources close to construction material storage

yad; Storm water drains may get choked due to silt loading flowing from the

collected/ stored spalls/so11 at eonstructlon slte. Concrete mixer plants and maintenance sltes of construction vehicles; and

Wlthln the viclnlty of project slte no major / deslgnated water body Is present

and moreover all the eonstrudlon related actlvltles are conflned to the

enclosed area, hence no major Impact on the water bodies In pmje!2 influenced area are antlcipated.

The accidental spills or bad construction pmblces may affect the near by dralns as

well as ground water quality of the area. The magnitude of such lmpact/s depends

upon the type and magnitude of the constructlon actlvlty. Chapt.r 6 on

Envlronment Management Plan (EMP) of thls report descrlbes the mitlgatlon

measures that a n needed to be taken to mlnlmlze such lmpab(s).

5.4.4 Contamination of Soil

The accldenb3l spillage, stacking or handlinp of oil and grease, cement, palnts, etc.

on open ground is llkely to affect the sol1 quality. However the magnitude of the

impact depends upon the severlty of quantum of material spills, etc.

5.4.5 Flora and Fauns

During the slte prepatatton actlvlty, 124 trees of dlfFerent sizes were recorded but

flnal permisslon of 58 trees to be cur with prior permisslon from Department of

Forests, GNCT Delhl was taken. As required, 10 tlmes of the trees actually cut and

5 tlmes of the trees transplanted wlll be planted as a part of compensatory

afforsstatlon, whlch has been described In more details in Chapter 6 (EMP). Hence,

In total 620 (10 x 58 + 5 x 8) were planted as a part of compensatory plantation

(Tabla 5.4. and Table 5.5.). Further, landsmplng lnvolvlng plantatlon of shrubs,

shady trees with large canopy, lawns, etc. wlll be developed as per the landscape

plan envisaged by DMRC for the proposed Metro Bhawan bulldlng ~0mplex. The

florlstlc component of the study area does not include any rare or endangered

specles. Thus, Impact on rare and endangered species of flora Is ruled out. The

As the project site is bounded by hlgh tmfflc denslty areas, hence dlsruptlon of

tramc due to movement of the constructlon vehlcles/machlnery may occur. The

disruption of trafflc was mlnlmlzed, by allowing these vehicles/ machlnerles move

only during non-peak hours that too durlng nlght hours. After reachlng the site,

these machlnerles / construction vehlcles were parked inside the project complex

so no trafflc dlsruptlon due to their operation/ movement took place at site.

The constructlon materlal used In Metro Bhawan comprised of Steel (3700 Mf),

bricks (15,000,00), concrete (22,500 m cement (1,92,000 bags), sand

(14,500m3), Coarse Aggregate (20,000 m3), fllllng sand (7,000 m') and ad mixture

(73,000 lltres) besides plywood (11,100 m2) and planks (50,500 re). The staklng of

construction material was mnflned to the project slte only. It was carried out In a manner so as to cause mlnlmal dlsturbanee (aesthetically and environmentally) to

the surrounding natural environment. Further, it should be disposed off periodically

at the dumping sites earmarked by DMRC for this purpose.

5.4.8 Construction Was-

About 62,000 m3 earthwork/ spoil generated were disposed at KSHI dumping Yard,

opposite Shastri Park Metro Station, Delhi. The construction waste consisted of

earth, debris concrete, lumber and manufactured wood produck, drywall, masonry

and cardboards. Apart from this, it also contained mix of roofing materials, metals,

plaster, plastics, foam, insulation, textile, glass and packaglng. The construction

debris along with the overburden generated during construction phase (1260 m3

approx.) has been disposed off at MCD disposal site situated at GT Karnal Road,

Delhi. In addition few items like approx. 1,30,000 bricks and 9.5 MT of steel were

sold as a scrap for reuse and recycling. A$ per the work contract document,

contractor was required to dlspose of spoils and other construction wastes to be

dumped at this site. Dust (fugitive emissions) was the main pollutant released

during construction phase. This was controlled through sprinklers etc.

5.4.8 Public hwlth and safety

Since all the construction related activities was confined to the project slte, no

health related impacts was envisaged in the project influenced a m during the

construction stage. A t the project slte about 600-700 persons were engaged in the

constructlon activities, faced direct exposure to dust, generated from construction

activity. This Is likely to cause health related problems like asthma, bronchltls, etc.

To mlnimire these anticipated impacts sprinkling of water at construction slte to

suppress the wind-blown dust suitable along with protective equipments such as

mouth mask was provided to the workers. The construction debris and waste

generated during construction malnly cause fugitive emission of dust hence are

pmvlded with helmets, gloves, safety shoes, eye shlelds, dust masks. Awareness

programme regarding the same was provided weekly extending upto 2-3 months

depending upon the need.

Final Report: EM &Me& BMwan, Banmamba Lane, Connaught Mace

8.4.10 Social Impacts

Slnce the labourers were hlred by the construction agency as per the terms and

conditions already specifled, hence no adverse soclal Impacts are envisaged due to

the proposed project.

5.5 Impacts due to Project Operation

Durlng the operation of proj@ct, there would be impact on air, water, land

envlronment and sodo-econamlc aspects. The following sectlons present the

impacts envisaged during the operation phase.

5.5,1 Alr Environment

The operation of proposed project does not envlsage any major air pollutant

generatlng sources except DG sets and vehicular movement. The DG sets proposed

will provide 100% backup In casa of power break down. Thus thclr use wlll be

Infrequent. For proper dlsperslon of the air pollutants from the proposed DG sets to

minirnlse the air pollution, a stack of appmx. 8m above the m f has been proposed.

5.5.1.1 Measure to Control Emission from the DG Set

Appropriate stack height for the exhaust of flue gases shall be provlded to rninlmlze

emlssion from the DG sets for the proper dispersion of gases wlthout increasing the

ground level concentration of the pollutant. The mlnimum helght of the stack shall

be as per CPCB/ MoEF guidelines using the formulae (Annexura VII):

H = h+o.z*v~ where,

H = Total helght of stack In metre

h Height of the buildlng in metres where the generator set is

installed

kVA = Total generator capacity of the set in kVA

In this case, four D.G. Sets (2x1500 kVA, 2x1000 kVA) will be Installed for 100

percent power back up, hence for the proper emission of gases from all the four DG

set, comblned stack of at least (44.75 - 37.0 m) 7.75111 (- 8 m) may be pmvlded.

Final Report. EM of Metro Bhewan, Barekhambs Lam, Connaught Pace

5.5.2 Noise Environment

The sound pressure level generated by noise source decrease wlth Increase in

dlstance, from the source due to wave divergence. An additional decrease in sound

pressure level with distance from the source is expected, due to atmospheric effect

or its lnteractlon wlth objects in the transmisslon path. The noise levels emanating

from varlous equipment, which shall be used during the operation stage are Qiven

The DG sets shall be used during power failure for controlling emergency

operations. The predictions have been made taking into account all operations and

utilities thus rdectlng the worst-case scenario. Noise level at a distance of 100

meters radius of the proposed sources Is expected to be around 40-45 dB-A, which

is well wlthin the boundary of recommendations given by World Health Organisation

(WHO) with respect to nolse level (Table 5.7) and should meet noise standard for

continuous exposure specified by CPCB (Annexure VII I ) . Table - ' "'Ha Recommendations

5.5.3 Water Supply Requirement

Flnal Repoe RA of Mcho Bhaww, Bamkhamba bm, Connaught Place

been made to recharge rainwater through roof-top rain water harvesting when the

Metro Bhawan becomes operational.

Durlng the operatlon, 64m3/day wastewater wlll be generated that wlll be treated In

the sewage treatment plant operated by the munlclpal corpomtlon through exlstlng

sewer llnes. Any burstlng or choklng of Internal sewer llnes In the bulldlng is likely

to cause adverse Impacts such as foul smell, unhyglenic mdltlons and health

related Impact on the occupants of the bulldlng. Perlodlc cleaning of these Internal

sewer llnes Is recommended. Further, the entire project lnfluenced area has been

developed as per the Master Plan 2001, thus the exlstlng sewerage system can very

well take the wastewater demand of the project.

5.5.4 Solid Waste

Solld waste generated durlng operatlon stage wlll be both blodegradable and non - biodegradable (paper, offlce statlonerles, computer statlonerles/flopples/CD) In

nature. It Is advisable that biodegradable and non - blodegradable waste must be

segregatedl collected and dlsposed off separately. For collecting the solld waste,

provision for appropriate bins has been made. Arrangement shall be made wlth

munlclpal authority to dispose the generated solld waste In sultable manner. Hence

no major Impacts are envlsaged.

5.5.5 Induced Davelopment

As per the Master Plan 2001, the project Influenced area has been developal to

meet the comrnerclal requirement in and around Connaught Place area. Hence no

lndueed development Is foreseen due to the construction of Metro Bhawan.

5.6 Posltlve Impacts

The operation of the project, provlde valua addltlon to the exlstlng Infrastructure

faclllty such as publlc transport, water supply, telecommunlcatlons, etc.

The operation of project and Other allled facllltles, wlll Improve the employment

opportunltles (direct or Indirect) at the proposed project site. The employment thus

generated wlll have posltlve Impact on the quality of llfe.

5.6.3 Enhancement of Publlc Health and Safety

All fire and safety measures as suggested by NBC (2005) have been Installed and

regular mock drills have been conducted at the project slte. Regular health check

up shall be carried for security guards and persons working near DG sets.

Chapter 6 Environmental Management Plan

6.1 Gsnaral The maln purpose of the Environmental Management Plan (EMP) is to

delineate all the measures to be undertaken durlng varlous phases of the

project to offset or mltlgate the adverse environmental Impacts (if any) to

acceptable level to protect the environment especially the communlty likely

to be affected by the proposed project. The EMP should necessarily cover all

phases of project cycles 1.e. piannlng and deslgnhg, construction and

operation. The potential Impacts on the environment due to the proposed

project were Identified based on the nature of aQivlties undertaken durlng its

construction and those envisaged to occur durlng Its operation in the llght of present status of the environment and legal compliance requimd. The

mitigation measures requlred to be takenlalready taken during various

stages of the project have been described below.

6.2. Mitigation Measures during Pm- Construc&ian/Demign

stags

The pre-construction stage measures already taken care in the project design

are as under:

Selection of Construction Material

Water Conservation

Energy conservation

Pathway for access

Landscape and Green Area Development

Workers Health Management

Earthquake Safety Measures

6.2.1. Selection of Construction Material

Use of burnt clay bricks in masonry is a common pmctlce In the country. The

Metro Bhawan does not Involve use of bulldlng with hlgh-embodled energy.

All the materials used In its construction (vlz., cement, brlcks, steel etc.), are

Flnal Report EM OT- Bhswan, 8smEdNlmbd Lana, Cormaught &a

those which are commerclaliy available. For other purposes, glasses of low

emlsslvity power have been used In the Metro Bhawan.

6.2.2. Water Conservation

The bullding construction projects requlre a large quantity of water durlng

construction and operation phase. Suitable arrangement needs to be made

prior to the start of project regarding the availablllty of water durlng these

phases. However, If these new bulldingS are to be constructed and put

operational In the major metros, speclal efforts to be made to mlnlmize and

conserve the water requirements. Based on the estimated water

requirement, a rellable source of water wlth the specified water quality

standards is essentlal. Further adequate armngements for storage facility

should be made t~ meet any contingencies. Also, now a days water

harvestlng from the offlce buildings/ has been made essential to recharge

groundwater table and as a measure towards water conservation. A

necessary provlslon needs to be made at the design stage to facilitate the

rainwater harvesting from the roof top. For guidance purpose, raw water

harvesting manual entitled "Rain water Harvemtlna and Conservation"

publlshed by Central Public Worb mpartment (CPWD) has also been

referred for detalled deslgn purposes.

6.2.3. Enemy Conservation The amount of energy used for lighting varles from Industry to Industry, but

typically, lighting accounts for approximately 50% of the electrical load m any office building. By using the lamps, ballasts, lumlnaries and control

options available today as well as the techniques used to develop efflclent

lighting; lighting can be produced that is both energy efficient and cost

effective. Improvements In lighting efflclency can be provlded In the bullding

by adoptlng following measures:

(I) Lamps - replacing Inemclent lamps with the most efficient lamp for the

purpose, taking Into account slze, shape, colour and output of the

lamp.

(ii) Ballasts - replacing standard choke ballasts wlth hlgh frequency

electronic ballasts.

(111) Lumlnarles - retroflttlng standard lumlnarles with high-effldency

spectacular reflectors or replacing standard lumlnarles with hlgh-

efficiency luminaries.

(Iv) Automatic Control systems - installation of (a) timer clrcuits that switch

lamps off during room vacancy times, (b) photoelectric sensors that

sense the amount of daylight in the room and elther switch lamps on

or off or adjust the lamp brightness accordingly and (c) occupancy

sensors that switch lamps off when work stations are unoccupied.

(v) Locallzed swltchlng - installing localized swltches near work stations to

control local llghtlng.

(vi) Llghtlng deslgn - (a) designing llghtlng systems that maxlrnlze the use

of dayllght, such as the PSAU system (permanent supplementary

artificial lighting in interlor$) and (b) Introducing local task llghts (e.g.

desks llghts), allowing a reduction in general overhead ilghtlng.

(vii) Maintenance schedule - setting up a maintenance schedule to clean

and replace lamps on a regular basls.

6.2.4. Pathway for Ac~eso

(I) The wldth of Maln Street on which the bullding abuts Is not be less

than 12m and one end of thls Street whlch joins another street Is not

less than 12m in width;

(ii) The approach to building and open spaces on all Its sides' upto 6 m

width and the layout for the same was done in consultatlon with the

Chlef FIre Offlcer of the clty and same was hard surface capable of

taking mass of the flre engine, welghlng upto 45 tonnes. The said open

space was kept free from the obstruction and was motorable.

(ill) The main entrance of the plot has adequate wldth to allow easy access

to the flre englne and In no case it measures less than 6m. The

entrance gate folds back against the compound wall of the premlses

thus leavlng the access way withln the plot free for movement of fire

vehlcie,

final &port &&I of Meho Bhavvan, BaraIdrah Lem, Connaught Place

(iv) As per the Bulldlng By-Laws, 2005, for the bullding of helght greater

than 35m (In thls case 37m), l l m was left for slde and rear open

spaces around the bulldlng.

6.2.5. Landscape and Grwn Ama Development

The greenbelt development/plantation In the Metro Bhawan area wlll not only

fundlon as landscape features resulting In harmonislng and amalgamating

the physical structures of proposed buildings wlth surroundlng envlronment

but will also acts as pollution slnk/nolse bawler. It will check soil erosion,

make the ecosystem more dlverslfled and functionally more stable, make the

cllmate more conducive and restore balance. All the land sites subject to use

of constructlon related actlvltles were restored to the origlnai settlng by

restoratlon and landscaping of the sites. Sites subject to excavation and

tampering of ground profile was rectlfled and done by the Contractor before

flnal closure of the construction activities. Landscaping of the areas wlthln

the premises of Metm Bhawan was also taken up durlng construction perlod.

Overall the project area was restored to the natural settlng In an

environmentally sound manner.

The project constructlon would Involve deployment of about 700 workers

durlng the peak period. Hutments for workers are not permitted at slte and

they will commute daily to the site. The labour hutments were provlded at

the batchlng plant at Kashmere Gate and Delhl Cantt. and few were on rental

basls. Also other facilities like tollets etc were provided at the project sltes,

hence no unsanitary conditions developed around the project slte. The

provision for safe drinking water would be arranged through the contractor.

Separate arrangement of WCs for gents and ladles was made wlth water

bound sanitation. A quallfled medical attendant with adequate medicines and

other facllitles was stationed at site throughout the constructlon period to

provide any flrst ald to the workers. The construction debrls and waste

generated durlng eonstruetion malnly cause fugitlve emisslon of dust hence

the labourers are provided with helmets, gloves, safety shoes, eye shields,

Flnal Report EM ofMctm Bhswn, BamMurnbu Lana, Cann8ught Race

dust masks. The awareness programme regarding the same was provided

weekly extending upto 2-3 months dependlng upon the need.

62.7. Earthquake Safety Messureo

The Delhl region come under Selsmic Zone IV, hence all measures to protect

the buildlngs built in thls region are In accordance to good practlee as

specifled under NBC (2005).

6.3. MitigatIan Measures during constructlon and Operatlan Phase

6.3.1. Air Quality

6.3.11. Durlng Construction Phase

The Alr Quallty around the project slte was affected durlng constructlon

stage. Various construction actlvitles especlally related to loose materlal are

likely to generate dust that Impacted the air quallty of the surrounding area

of the project site, In order to mlnlmlza impacts especlally from these

fugitive emlssions, following measures were taken:

(I) All the loose materlals were transported with sultable coverlng etc.

(li) Water sprinkling was carried at the locatlon where dust generation

occurred.

(iii) Care was given to personnel Involved in the dust generatlon activity in

terms of provision of safety masks etc. to avoid any health hazard #r

them.

(Iv) Transportation of constructlon materlals was carrled out durlng non-

peak hours.

(v) t o minlmlse dust emission due to handling of aggregate and cement at

slte, ready mlx concrete were carried in translt mlxers.

(vi) As the vehicular movement may lead to fugitive dust In the area,

hence provlslon was made for sprinkllng of water on the roads at least

once a day durlng the entlre construction period.

(vll) Every day the haul road at the construction site was inspected and the

debrls left by the tractor - trolleys was removed as early as possible.

(vlli) Vehlcle speed was restricted to 15 kmph applied at slte.

Final Report EM of Metm Ehawan, Barakhamba lane, mfmaupht Ram

(Ix) Downwash of trucks (especlaiiy tyres) prior to departure from Site.

(x) Proper care was given for the storage of furnace oil, LDO, etc.

(xi) The work schedule and the operation tlme of each construction

machlnery was suitably modlfled to optimist2 the use of construction

machlnery.

(xll) All statlonary machines/ DG sets emltting the pollutants was Inspected

weekly for malntenance and were fitted wlth exhaust pollution control

devices.

6.31. Reduction of Incremantal Air-pollution through Traffle Manau~mant

Reduction in incremental air pollution from vehlcuiar emissions In the Metro

Bhawan project has been aimed through state of the art trafflc management.

Salient features of the trafflc management have been glven below.

(I) Adequate and clear warning signs were displayed at appropriate

distances before the commencement of the slte workings. In addltlon

prior warnlng will be glven concerning the iocatlon of the approaching

slte entry and exlt points.

(it) Slte vehicles exltlng the site obsenred caution at all times. I f the

vehlcles were exltlng dlrectly onto the llve carriageway then they were

directed by an identifiable Traffle Controller.

(ill) Regular inspection of the trafflc management schemes was conducted

by contractors in both the day-time and night-tlme hours which wem

recorded.

8.3.2. Nolw Control 6.3.2.1. DurlnQ Conetruction Phaae During the construction phase, there would be a temporaw Increase In

ambient noise levels due to operation and movement of constructlon

vehlcles. In this project, belng a buiidlng constructlon work, the magnitude

and use of machinery is llmlted exclusively to the project slte. Though the

Industrial countries have speclfled limits for occupatlonal noise exposure, the

permlsslble nolse exposure limit for lndustrial workers is primarliy concerned

wlth harmful effects of noise and its objective is to protect the hearlng of working people. The exposure to cantlnuous and Intermittent noise levels

louder than 115 dB (A) should not be permitted. Foiiowlng mltigation / management measures were adopted during construction period:

(I) Special acoustic enclosures shall be provided for individual nolse

The total sound power level of a DG set, at the user's end, shall be

within 2 dB (A) of the total sound power level of the DG set, at the

manufacturing stage as prescribed under (A).

Installation of a DG set must be strldly in compliance wlth the

recommendations of the DG set manufacture.

A proper routlne and preventive maintenance procedure for the DG set

should be set and followed in con5ultatlon with the DG set

manufacturer which would help prevent noise levels of the DG set from

deteriorating wlth use.

6.3.2.2.4 Poilutlon Control throuah Plantlltlon The air and noise pollution control can also be enhanced by planting certaln

species of plantsftrees. Some of floral specles which can be glvan preference

while developing the green areas of the project are: Ficus rellglosa (Pipal),

Aibiuia lebbek (Slrls), Cassia flstuia (Amaltas), Zirphus jujuba (Ber),

Azadirachta indica (Neem), Tamarindus Zndus (Imli), Daibergia sissoo

Nerlom lndicum (Kankar).

6.3.3. Water Requirement 6.3.3.1. During Construction Phase: About 8,820 KLD of water was

drawn from the existing tube wells in the metro site, of which 50% was used

In the concrete and remaining 50% was used far the labourers, curing etc.

6.3.3.2 Durlng Operation Phase: The water requirement at the

proposed Metro Bhawan has been estimated to be approx. 80 m3/day. The

details have been given below In Table 2.3. It is proposed to get the whole

of the water supply for drlnklng purpose from the NDMC through the exlsting

water pipe lines. Necessary permission regarding the quantlty of water to be

used for drlnking purpose has already been obtained from NDMC. It is

proposed that the municipal water supply wlll be stored in the over - head

water tank and thls water will be supplled in the bullding through gravity.

Final Report EIA Or McND Bhawan, Bevatdramba Lane, Connaught Place

Four water tanks of varlous capacltles have been Installed In the basements

(Table 6.4.) and two tanks (one each for drlnklng water and flre purposes)

of 20 m3 (20,000 lltres) have been provldad at the terrace.

Tabla 6.4.: Capaelty of water Tanks In the basement of Metro Bhawan

During operation perlod about 64 m3/ day of sewage wlll be generated from

the project, whlch wlll be dlsposed to the external munlclpal sewer adjacent

the site. A no. of measures to reduce the mnsumptlon of water that will be

followed are as under:

Reduction of tollet clstern volume in single flush models,

Promotion of awareness on water conservatlon and reduclng water

usage, Promptly attending the water leakages,

Provldlng urlnals and wash basins wlth autornatlc sensors and WCs

with flushing valves,

Sprinkler irrlgatlon system for watering of green spaces, Plants wlth slmllar water requirement

6.3.3.3. Raln Water Harvesting

In addition three ralny wells have been constructed to carry out rainwater

harvesting, purely for recharging purposes, In the Metro Bhawan rainwater

wlll be harvested from rooftop and paved and unpaved areas l.e.,

landscapes, storm water dralns, roads and pavements.

6.3.5. Solid Wamtm Managemmnt

6.3.5.1. Durlnp Constructson Phase

The recycling of construction waste was done as follows:

(1) Left over concrete and mortars, cement concrete blocks, aggregate,

sand and other lnorganlc material was recycled and used as

Granular Sub-base (GSB) layer of pavement.

Reuse of this wlll also save an equivalent quantlty of aggregate.

About 62,000 cu.m. of earth rendered surplus from the excavatlon

will be utillsed In the embankment of DMRC works. As a result

there would not be any Inorganic solld waste rendered surplus from

the project and requir~ng d~sposal.

Final Repott EDI oPPletn, Bhawan, Barakhatnba Lsnc, Connaught Plsce

Recycling and reuse of solld waste arising out of various constructlon

activities, which was lnotganic in nature, has been discussed above.

Domestic solid waste during construction was limited because no labour

amps were permitted at site. However, even when there was no labour

camps at site and most of the inorganic construction waste was recycled and

reused In construction, there still remalned some solld waste requiring

collection and disposal. This Included food waste of workers at site, empty

containers of pain& and ather chemicals, packagln~ of tiles and glass,

sweepings from omce etc. Following measures were adopted during

constructlon for management of solid waste.

(1) Covered garbage bins were provided all around the construction site including office for collection of food and other waste. These blns

were emptied daily Into a bigger container and the waste finally put

to municipal (NDMC) collection bin, nearby. The waste bins were

washed regularly every week.

(11) Inorganic waste was segregated and kept in different heaps as far as possible so that their further gradatlon and reuse was facilitated.

(ill) Material, which could be recycled and reused for the purpose of

construction, was kept in separate heaps from those which were to

be sold or disposed off.

(Iv) Empty containers, which may contain some toxlc substances such as

paints, solvents, adhesives and sealants was returned to the

manufacturers or disposed appropriately as the case may be. Tlll

such time they were stored safely.

6.3.5.2. During Operation Phesa

The project is estimated to generate about 320 Kg of solid waste every day.

Majority of the solid waste will comprise of waste papers, food waste and

green area sweepings, all of them are biodegradable. The non-biod@gradable

waste will comprise of the floor and road sweepings and the IT waste, which

include used computers and floppy disks. The blodegradable and non-

biodegradable waste shall be segregated during collection by uslng different

colour bins for different type oP waste. Every workstation shall be provided

Final Report EM afrcrsirer Bhswan, Bsmkhmba Lana, tonnawnt Mace

with such bins. In addition collection blns shall be provlded at sultable

locations In common place and open area for waste collection from floatlng

population. The biodegradable as well as the non-biodegradable waste shall

be transferred everyday to the larger blns kept outside the bulldlng at sultable place. To avoid odour and accumulation of fly-supporting materials,

waste collection blns shall be washed at frequent intervals. The waste shall

however be stored in a separate facility and shall be disposed off through an

authorlsed person/agency of NDMC for that purpose.

Qreenbelb and Landscaplng

Greenbelts and Landscaplng besldes enhanclng the aesthetic beauty of the

bullding complex also helps In improving environmental quality. The cholce of

sultable trees is known to curb the impacts of alr pollution as it act as a fllter.

Thls should be given utmost Importance taklng advantage of both shades and

sunshlne without obstructing the wlnd flow and traffic. Further, a total no. of

620 trees was planted through the necessary afforestation programme, in

lieu of the 58 trees to be cut (Tabla 5.4.) (10 trees for every tree permitted

to be cut) and 40 trees In lieu of the 8 trees (5 trees for every tree to be

transplanted). These were planted as a part of compensatory plantation at

the Gaon Sabha land, Isapur (a site Identified as a part of NOC).

6.3.7. Spaclal Requirement for Physically Challengd

(I) Parking lot has been made keeplng in mlnd requlrement of a physically

challenged person.

(11) Entrance has been designed keeplng in mind the need of physically

challenged person (as shown in Fig. 5.1).

(lii) Stalrs are not be the only means of moving between floors. They are

supplemented by lib and ramps.

(Iv) Sanltary facllltles shall have space to allow trafflc of wheelchair bound

persons. In case of Metro Bhawan such facllltles has been provided at

the second and flRh floors.

(v) Drlnking water fountains or coolers are hand operated O r hand & foot

operated.

Final Report EM Or- B h o m , BamMmmh Lane, Gornnawght Place

An abstract of the EMP for the project has been prepared and presented In

Table 6.6. whlch deflnes actlons to be undertaken during the pre-

constructlon/design (Includlng those already undertaken), wnstructlon, and

opemtlon stages of the project. The mltlgatlon measures given in the table

have been described In the subsequent paragraphs. In addltlon a revlew of

the legal compliance has alsa been carded out (Table 6.7.). The Important

actlons during the pre-constructlon/desl~n stage was energy mnsewatlon/

natural ventllatlon, water consewatlon, reduction In Incremental alr pollution

through tmfflc management, envlronmental enhancement, flre management,

and non - lncluslon of environmental management related clauses in work

contract. The constructlon stage mltlgatlon measures Include control of alr

emlsslans, nolse pollutlon, sol1 eroslon, surface runoff, disposal/ recycle of

constructlon waste, solid waste management, non - routine events and

accidental release, workers safer// health hazard, and envlronmental

management cell/ unlt. The operation perlod rnitlgation would Involve control

of air emlsslons, nolse pollutlon, wastewater dlscharge, solld waste

management, Indoor air pollutlon, energy uses, emergency preparedness

lncludlng flre management, envlronmental management cell/ unlt.

Final Report: EM or mtm B ~ P I W ~ , mmhsmt~ bne, c4nnswht f laa

Chapter 7 Post Project Monitoring (PPM)

7.1 General

Implementation and follow up are used to identlfy the impacts that occur; check

that these a n withln the levels predicted and stipulated standards; determine that

mitigation measures are properly implemented; ensure the environmental beneflts

expected are being achieved; and provide feedback to improve future applications

of the EIA process. Wlthout appropriate impiementatlon and follow up to declslon-

maklng, EIA b a m e s a paper exercise to secure an environmental clearance,

rather than a practical exercise to achieve environmental beneflts. The purpose of

EIA implementation and follow up Is to ensure that the conditions stipulated in

environmental clearance are implemented and function effectively, and to galn

Information that mn be used to improve EIA practlce in the future. The major

components and tools of EIA implementatlon and follow up which are proposed to

be followed as a part of EIA exercise Include the following:

(I) Surveillance and supervision - to oversee adherence to and implementatlon of

the terms and condltlons of project approval

(ii) Effects or impact monitoring - to measure the environmental changes that can

be attributed to project construction and / or operation and check the

effeeblveness of mltigation measures

(ill) Compliance monitoring - to ensure the applicable regulatory standards and

requlrements are belng met, e,g. for waste discharge and pollutant emissions

(iv) Environmental audlting - to verlfy the Implementation of terms and conditions,

the accuracy of the EIA predictions, the effectiveness of mitigation measures,

and the compliance with regulatory requlrements and standards ;

(v) Ex-post evaluation - to review the effectiveness and perFormance of the EIA

process as applled to a specific project ; and

(vi) Post-project analysis - to evaluate the overall results of prole& development

and to draw lessons for the future
