1. Introduction
1.1 About the Project
1. ADB approved the Climate Adaptation in Vennar Subbasin in Cauvery Delta Project
(CAVSDP) on 7 June 2016 for $100 million. ADB and the government signed the loan on
14 July 2016 at the Department of Economic Affairs (DEA), New Delhi. The Water
Resources Department (WRD) of the Public Works Department, Government of Tamil
Nadu, is the executing agency for the project. The project aims to modernize irrigation and
flood management infrastructure and establish improved management systems to help
local communities in the Vennar Sub-basin of the Cauvery Delta of the State of Tamil
Nadu adapt to climate change. The impacts will be (i) coastal districts are protected from
cyclones and flooding exacerbated by climate change and (ii) innovative and inclusive
economic growth, including agricultural growth, in Tamil Nadu is accelerated. The
outcome will be that climate-resilient water management in the Vennar system is
improved.
2. The outputs of the project are: (i) flood risk management and irrigation infrastructure
upgraded, and (ii) improved water and flood risk management systems established.
Output 1: Flood risk management and irrigation infrastructure upgraded. Structures will
be improved according to new design guidelines that consider climate change impacts.
More-resilient flood management structures will reduce the frequency and impact of
flooding. The civil works involve (i) resectioning, and strengthening the embankments of,
six main channels totaling 235 kilometers to improve their resilience and flood conveyance
capacity; (ii) improving conveyance of three straight cuts between the Vedharanyam canal
and the sea (iii) constructing 4 new regulators, reconstructing 10 dysfunctional regulators,
and repairing 13 damaged regulators; (iv) doing work (new, upgrades, and repairs) on 133
irrigation head sluices off-taking from the main channels; (v) upgrading 20 bed dams and
grade walls within the main channels; (vi) upgrading 136 other minor irrigation and
drainage structures; and (vii) upgrading 13 pump stations through new pumps and
electrical systems and repairs to pump houses.
Output 2: Improved water and flood risk management systems established. This output
will deliver nonstructural interventions designed to (i) improve decision-making on water
resources, and (ii) manage flood risks and flood events. Initiatives to be developed under
item (i) are: (a) greater participation by stakeholders in the planning and delivery of water
services through the formation of channel stakeholder groups; (b) better assessment of
7
water resources through the installation of additional equipment to monitor and measure
rainfall, surface water, groundwater, tide levels and flows; (c) development of a decision
support system that would provide system status information and enable more accurate
water allocation planning and more effective asset management; and (d) training for WRD
officers on more effective management of water resources. Flood risks and flood events
will be managed by (i) installing flood forecasting and warning systems, and (ii) mapping
flood risks. The output also includes a feasibility study, and the detailed design of similar
improvements in the remainder of the Vennar and Cauvery systems that may be financed
under a subsequent project.
Project Description
3. Background- The Cauvery Basin is the largest of 17 river basins in Tamil Nadu and is
located in Karnataka, Kerala and Tamil Nadu. The sub-areas of the Cauvery Basin lie
within each of the three riparian states and the enclave of Karraikal in the Union Territory
of Puducherry. The project includes structural and non-structural measures to support
improved flood and irrigation management to help communities in the Vennar sub-basin of
the Cauvery delta adapt to climate change. WRD of the Public Works Department (PWD),
Government of Tamil Nadu, is the executing agency. The project includes re-sectioning of
river/canals, de-silting of river bed, construction of new or rehabilitation old or
reconstruction of head regulators, cross regulators, drainage outfall, irrigation outfalls and
infalls on rivers. In addition, the program will support improvements to water resources
management in the Cauvery delta by implementing improved monitoring and decision
support system (DSS).
4. Vennar System - The Vennar system comprises ten main river channels that are used to
convey irrigation and drainage waters. In addition, ten other channels are used purely as
drainage channels to convey flood and drainage water, although some have been adapted
to enable drainage water to be used by pumped irrigation schemes in lower reaches. The
system has 7 head regulators at major river bifurcation points, 188 intermediate regulators
that facilitate the distribution of irrigation flows and 11 tail-end regulators (TERs). TERs
serve the dual purpose of raising water levels to provide irrigation to low lying command
areas near the coast and preventing tidal backwater flows into the system. When heavy
rainfall occurs and drainage congestion takes place, TERs are opened to allow outflows,
although high tides and storm surges restrict discharges to the sea.
8
5. The Vennar system has two distinct coastal zones: (i) The eastern coast along the Bay of
Bengal from Point Calimere to Nagapattinam immediately inland of which small remnants
of lagoons and marsh are joined together by the Vendharanyam Canal. The canal was
constructed between 1863 and 1867 to aid navigation between the salt producers south of
Thopputharai and the port at Nagapattinam to the north. Between the Vendharanyam Canal
and the sea there is a 3–4 km strip of sand dunes. Five straight cuts were constructed across
the sand dunes to directly link the Vendharanyam Canal and some of the Vennar system
rivers to the sea to supplement the flow through two ‘natural’ outlets at Vendharanyam and
Velanganni. Sections of the Vendharanyam Canal and some of the straight cuts are heavily
silted. The canal is no longer used for navigation and is now solely a drainage carrier for
the east bound rivers of the Vennar system. However, there is a government proposal to re-
establish navigation on the Vedharanyam Canal. (ii) The southern coast along the Palk
Strait from Point Calimere to Adirampattinam where the south flowing rivers and drains of
the Vennar system cross 4–6 km of tidal sand flats into two large lagoons that are
connected to the sea through 1–2 km wide openings.
6. The project will improve irrigation water management in six channels namely Pandavayar,
Vellaiyar, Harichandranadhi, Adappar, Valavanar, and Vedaranyam Canal, covering a total
command area of 78,000 hectare (ha) in the Vennar sub-basin of the Cauvery delta sprawl
in Thiruvarur and Nagapattinam districts (Figure 1), of the state of Tamil Nadu, through
investments in infrastructure, water resources management, and flood risk reduction.The
drainage system of the Vennar basin is unable to cope with the floods resulting from
present climatic conditions. Man-made interventions and natural processes combine to
impede drainage and aggravate flooding particularly on low-lying agricultural land.
Climate change is expected to make flooding worse due to more intense and unpredictable
rainfall. The delivery of irrigation flows to farmers is becoming more erratic and unreliable
as the aging structures impede the efficient management of irrigation flows. Many
irrigation management structures have deteriorated to an extent that they are no longer
effective and are well passed their useful life. The present management of floods and
irrigation distribution is outdated and does not utilise modern technologies to ensure
efficiency and transparency.
9
7. The management needs to become more systematic, efficient and based on scientific
information to inform decision making, with specific targets that are explicit in terms of
cost, water and other resources to meet environmental requirements. Therefore the scope
of the project is to improve the performance of six river channels in anticipation that
further investment will be subsequently made to modernize the drainage and irrigation
channels within the command and catchment areas of the system. The six river channels
have been taken as the critical entry points because they are the backbone from which all
other improvements to the drainage and irrigation systems will extend.

8. The proposed project includes re-sectioning, regrading, standardisation, repair,
reconstruction and new construction of structures in the rivers. De-silting of rivers is
required in throughout its length starting from its head regulator to the end. The Vellaiyar,
Lawford and Adappar and Uppanar straight cut of Vellaiyar River, Harichandranadi River,
Adappar River and Vedaranyam Canal where dredging is proposed to excavate below
water to remove silt and sand. The summary of the rivers are given in Table -1.1.
9. The proposed works of Project are (i) Re-sectioning of the river channel which includes
cleaning the channel of vegetation, desilting/dredging and widening. (ii) Re-grading of the
river channel which includes excavation of the channel bed to remove sand bars and other
10
impediments to restore the channel to its design section. Also known as de-silting. (iii)
Standardization of banks which includes raising and strengthening of the embankments,
decreasing bank side slopes, increasing top width, construction of road etc. to bring the
embankment back to Bureau of Indian Standards (BIS) to withstand 25 year return floods
taking climate change considerations into account. Repairs of structures–head regulator,
cross or intermediate regulators, TERs, irrigation sluices, drainage sluices, drainage infalls,
irrigation syphons, drainage syphons, bed dams and grade walls. Repairs are the
restoration of the components of the structures to function as designed. (v) Reconstruction
of existing and construction of new head regulators, cross or intermediate regulators,
TERs, irrigation sluices, drainage sluices, drainage infalls, irrigation syphons and drainage
syphons, bed dams, and grade walls. Reconstruction is the demolition and removal of all
components of the existing structure and construction of new structure including
foundations on the same site. (vi) Fluming and River Training. Bank revetment/pitching
and masonry walls depending upon severity of the problem of bank failure and availability
of land. The total length of the river channels to be re-sectioned or re-graded is 234.50 km.
The number of new structures and the existing structures to be reconstructed and
repaired/rehabilitated is given in Table -1.2.

2. Project’s Environmental Safeguards
11. The project is categorized B as per ADB’s SPS 2009. An initial environment examination
(IEE) was prepared for the project and includes an environmental management plan (EMP)
which describes mitigation measures to be adopted during design, construction and
13
operation. Environmental issues identified through initial environmental examination
(IEE) are manageable and a range of proven mitigation strategies exist to address them.
The IEE has assessed all potential environmental impacts associated with the project due
to location, design, construction and operation. There are no environmental impacts which
are significant or complex or which need an in-depth study to assess the impact or to
develop mitigation measures. The environmental impacts identified are manageable, and
the Water Resources Department (WRD) is in process of implementing the project
according the mitigation measures stated in the IEE
12. Mitigation measures have been developed to reduce all negative impacts to acceptable
levels. The mitigation measures are described in the environmental management plan
(EMP).An environmental monitoring plan (EMoP) has also been developed to assess the
environmental performance of each sub-project implementation. The mitigation measures
have been incorporated in project designs and implemented as part of each sub-project.
Most of the mitigation costs are included in the construction costs. Costs for monitoring
and tree planting are not included in the construction cost and are included under the
project management unit (PMU) expenses.
Purpose and Scope of Report
13. The report has been prepared in line with the implementing the IEE and its EMP.The
report documents the implementation of EMP and the results of the Environmental Quality
Monitoring for all the ongoing Civil works package of the Climate Adaptation in Vennar
Subbasin in Cauvery Delta Project (CAVSDP). This report presents the results of the
environmental management and monitoring activities from December 2016 to May 2017.
The report covers the:
a. environmental capacity building activities conducted during the period;
b. Status of compliance with ADB environmental loan covenants and with the
environmental requirements of the Government of Tamilnadu during the report

Management
The borrower/client will assess
the significance of project
impacts and risks on
Biodiversity and natural
resources as an integral part of
the Environmental assessment
process.
Environmental issues identified
through initial environmental
examination (IEE) are manageable and
a range of proven mitigation strategies
exist to address them. The IEE has
assessed all potential environmental
impacts associated with the project due
to location, design, construction and
operation. There are no environmental
impacts which are significant or
complex or which need an in-depth
31
study to assess the impact or to develop
mitigation measures.
9. Pollution
Prevention and
Abatement
The borrower/client will apply
pollution prevention and
control technologies and
practices consistent with
international good practice, as
reflected in internationally
recognized standards.
Air emission during construction stage,
may possibly be arises from operation
of construction vehicles, equipment,
haulage of material and earth, dust
generation from earth work. The
resection of river and construction of
embankment are throughout all 6 rivers
namely, Pandavayar, Velleiyar,
Harichandranadi, Adappar,
Vedhanarayam and Valvanar. The
cumulative lengths of all six rivers are
235 km. The construction of
embankment will generate dust but it
will be localized to the construction site
and may have little impact due to
generation of dust in residential,
commercial and sensitive location like
schools. These locations are already
identified and regular sprinkling of
water on exposed earth has already
been suggested and also under practice
by the contractors. These residential
areas are adjacent to the boundary of
the rivers. The impacts are not
significant or equivalent to the dust
generated in agricultural land during
ploughing.
The mitigation measures for
suppression of dust near the residential,
commercial and area of socially
important places like temples and
churches are required through
30
sprinkling of water on exposed working
areas. (The transportation of silt is
required to be done in covered trucks.
Annex.11) Regular checking of
pollution emission from the
construction vehicles exhaust is being
done from the authorized agency and
relevant Pollution under Control (PUC)
certificates obtained. (Annex.7)
Noise generation during construction
stage arises from operation of
construction vehicles, equipment,
haulage of material and earth. The
impacts are not significant and is
limited to construction hours in day
time only.
The mitigation measures includes
proper maintenance of construction
vehicles so that it do not generate noise
while operation. The use of pressure
horn in the habitation area must be
avoided. No horn signage are provided
near the schools.
10. Health and Safety The borrower/client will apply
preventive and protective
measures consistent with
international good practice, as
reflected in internationally
recognized standards
Preventive and protective measures are
being applied with good practices.
Safety Manual and celebration of
Safety and Quality day is required to be
in practice by the contractors.
All contractors of CW-1,CW-2,CW-
3,CW-4,CW-5 & CW-6 are engaging
local lobour wherever the local labours
are available and they already
31
encouraged to recruit local people as
labourer at least for unskilled and semi-
skilled jobs. This practice of engaging
local labourer automatically reduced
the magnitude of impact expected due
to outside labour. In all the contract
packages there are very limited
numbers of outside laboures and for
their accommodation the contractors
already rented houses/buildings with all
necessary facilities like water,
electricity, toilet etc in the nearby
villages of the construction site. The
package wise details of the Contractors
rented houses as permanent lobour
camp is attatched as Annex 10b.
Apart from that the contractors
provided temporary shades near work
areas treated as resting places near the
construction sites which are generally
used by the labours as a resting shadow
place during lunch hours.
All labours are provided with
safety equipments such as helmets,
gloves, working shoes/boots etc and
they are enforced to wear the required
safety equipments.
32
11 Physical Cultural
Resources
The borrower/client is
responsible for siting and
designing the project to avoid
significant damage to physical
cultural resources.
There is no archaeological site within
or near the proposed project sites. Any
chance finding will be taken care
according to Archaeological Survey of
India. These chance finds can be ruined
structures under the ground. This is not
expected because there no deep
excavation involved.

Compliance with Project Environmental Management Plan
24. The Project activities includes upgrading of the irrigation system which comprise re-
sectioning of river/canals, rehabilitation of embankments, de-silting of river bed,
construction of new, or rehabilitation of old, or reconstruction of head regulators, cross
regulators, drainage outfalls, irrigation outfalls and infalls on the Harichandranadi,
Adappar, Pandavaiyar,Vedhanarayam ,Vellaiyar rivers and Valavanar River/Drain in
the Vennar system. Environmental issues identified through initial environmental
examination (IEE) are manageable and a range of proven mitigation strategies exist to
address them.
25. The IEE has assessed all potential environmental impacts associated with the project
due to location, design, construction and operation. There are no environmental impacts
which are significant or complex or which need an in-depth study to assess the impact
or to develop mitigation measures. Mitigation measures have been developed to reduce
all negative impacts to acceptable levels. The mitigation measures are described in the
environmental management plan (EMP).An environmental monitoring plan (EMoP) has
also been developed to assess the environmental performance of each sub-project
implementation. The mitigation measures have been incorporated in project designs
and implemented as part of each sub-project (package). Most of the mitigation costs are
included in the construction costs. Costs for monitoring and tree planting are not
included in the construction cost and are included under the project management unit
(PMU) expenses. The contractors entrusted to strictly implement the EMP along with
the implementation of the project. The mitigation measures suggested in the EMP and
its implementation status are presented in Table 3.4.

Environmental Monitoring of the project
26. The IEE has identified the Environmental issues likely to be occurred during the
implementation of the project. Environmental issues identified through initial
environmental examination (IEE) are manageable and a range of proven mitigation
strategies exist to address them. The IEE has assessed all potential environmental
impacts associated with the project due to location, design, construction and operation.
There are no environmental impacts which are significant or complex or which need an
in-depth study to assess the impact or to develop mitigation measures. Mitigation
measures have been developed to reduce all negative impacts to acceptable levels. The
mitigation measures are described in the environmental management plan (EMP).An
environmental monitoring plan (EMoP) has also been developed to assess the
environmental performance of each sub-project implementation.
27. The mitigation measures proposed have been incorporated in project and implemented
as part of each sub-project. Most of the mitigation costs are included in the construction
costs. Costs for monitoring and tree planting are not included in the construction cost
and are included under the project management unit (PMU) expenses.. Similarly, the
impacts during the construction activities are now being regularly monitored and the
shortcomings observed during the field visits have been communicated to all concerned
with the for remedial measures.
28. During the implementation stage the contractor and project management unit (PMU)
and PIUs are responsible for the implementation of environmental management plan
and environmental commitments made to regulatory agency, lending agency and
stakeholder. Execution of the EMP, is the combined responsibility of WRD, consultant
and contractor. The day to day environmental monitoring and supervision is required to
be done by the Site Engineers (Assistant Engineers/ Junior Engineers of WRD) in
consultation with the SDO of PMU Environmental specialist.
29. PMU with support from the PIU engineers monitored and measured the progress of
implementation of environmental management plan and monitoring plan suggested in
the IEE. The regular quarterly progress reports of the contractors to be submitted to the
PMU will also describe implementation of environmental management plan. The officer
42
of WRD designated for safeguards officer in the PMU and environmental specialist will
make site visit to verify the compliance of quarterly report. Semi environmental
monitoring reports will be prepared by the PMU and submitted to ADB. The contractor
will report on implementation of the EMP in their monthly progress reports to be
submitted to the PMU.
30. At present the civil construction works under the six packages are ongoing. During the
reporting period seasonal Air quality monitoring, Noise quality, Surface Water Quality
& Ground Water Quality monitored under four contract packages and i.e. for, 4(Four)

31. For ambient air, noise, Surface water & Ground water quality assessments, samples
were collected at important locations within the project influence area in terms of
environment quality to prepare a baseline data. Representative samples were collected,
analyzed and interpreted by a NABL Accredited Laboratory, in accordance with the
approved standard methods and procedures. Consultations, another source of
information to explain local conditions like submergence, recent floods etc were also
used.
43
Ambient Air Quality
32. Ambient air quality refers to the background air quality levels in a region, characterised
by concentrations of various pollutants in the atmosphere. The presence of air pollutants
and their concentrations depends on the type of polluting sources, and other factors that
influence their flow and dispersion. In most cases vehicular emissions are the
predominant source of air pollution. The ambient air quality data on various sections of
the project corridors was collected at the time of execution of the work. The aim was to
identify areas that already have high pollution levels or are expected to experience so,
on account of the project work, and to design adequate mitigation measures, as
applicable.
33. The principal sources of air pollution due to river projects are machineries used during
construction phase and the vehicles that ply over it during the operation phase. The
major pollutants of significance to roadside air quality, on account of vehicular
emissions, are particulate matter (PM10), particulate matter (PM2.5), sulphur dioxide
(SO2), nitrogen oxides (NOx), carbon-monoxide (CO).Dispersal of pollutants depends
upon factors like prevailing wind direction and other weather conditions, height of the
source, and characteristics of corridor plantation and presence of other sinks along the
project corridor. Ambient air quality standards : National Ambient Air Quality (NAAQ)
standards were laid by CPCB to be followed in the country.The relevant parameters for
which standards have been formulated are PM10, PM2.5, SO2, NOx, and CO.
Standards for Hydrocarbons have not been formulated as yet.

Ambient Noise Level Monitoring
35. The monitoring of the ambient noise quality for the various land uses along the project
corridor was carried out with the help of hand held noise level meters.
Methodology of Noise Measurement:
36. Spot noise measurement was used for this purpose. The sound pressure meter consists
basically of a microphone and an electronic circuit including an attenuator, amplifier,
weighting networks or filters and an indicating display unit. It measures the root mean
square sound pressure with the aid of a microphone, which converts the sound signal to
an equal electrical signal. The signal is passed through a weighting network, which
provides a conversion and gives the sound pressure level in dB. The A-weighting
network is the most useful one on the sound level meter for measuring human response.
It indicates the A-weighted sound level, abbreviated dB (A). Sound level meter has a
provision to take reading in slow, fast and impulse modes. Traffic change with time, and
slow mode was used to average out the readings over 24 hourly longer periods.
Readings were taken in auto mode, which continuously update automatically to show
the maximum Sound Pressure Level of each (previously) second.
37. Keeping in view of various land use patterns and residential areas in villages 60 noise
level measurement locations were identified for assessment of existing noise level
status. At each monitoring station, the noise levels recorded continuously for 24 hours.
Hourly data has collected from each sampling point for 24 hours and day and night
values were given separately in Tables.
52
38. Hourly noise levels are recorded at each site and the measured noise levels are
computed for finding out Lday, Lnight and Ldn values.
Lday, Lnight and Ldn values
The Leq is the equivalent continuous sound level, which is equivalent to the
same sound energy as the actual fluctuating sound measured in the same period.
This is necessary because sound from noise source often fluctuates widely during
a given period of time.
This is calculated from the following equation:
Leq=L50+ (L10-L90)2/60
Lday is defined as the equivalent noise level measured over a period of time
during day ( 6 am to 10 pm). Lnight is defined as the equivalent noise level
measured over a period of time during night (10 pm. to 6 am).
A noise rating developed by Environment Protection Agency, USEPA for
specification of community noise from all the sources is Day-Night Sound Level,
(Ldn).
Day-Night Sound levels (Ldn)
39. The noise rating developed for community noise from all sources is the Day-Night
Sound Level, (Ldn). It is similar to a 24hr equivalent sound level except that during
nighttime period (10pm to 6am). A 10Db (A) weighting penalty is added to the
instaneous sound level before computing the 24hr average. This time penalty is added to
account for the fact that noise during night when people usually sleep is judged as more
annoying than the same noise during the daytime.
40. The EPA has adopted Ldn as the rating method used to describe community noise
exposure. To arrive at a recommended outdoor Ldn criterion, the EPA recommends that
an Leq of 45 Db(A) should not be exceeded indoors in residential buildings: this allows
freedom from speech interference. If the outdoor and indoor attenuation is taken, on
average, as 12db (A) with the windows partially open, this implies an outdoor criterion
of Leq = 60db (A). The EPA applies correction to this account for other annoyance
factors, including the 10db (A) nighttime penalty and a 5db (A) margin of safety, to
arrive at a recommended criterion of Ldn = db (A) as a desirable maximum outdoor
noise level for residential areas. It should be noted; however that majority of urban and
suburban areas are currently subjected to noise levels greater than this value.
The Ldn for a given location in a community may be calculated from the hourly Leq ,S,
using the following equation.
Ldn = 10 log {1/24[16(10 Ld/10) + 8 (10 Ln + 10) / 10)]}.
53
Where Ld is the equivalent sound level during the daytime (6am to 10pm) and Ln is the
equivalent sound level during the night time (10pm to 6am).

Quality Monitoring Conclusion:
45. Ambient air sampling was carried out at 24 stations, as detailed in Table 3.5.4 – Table
3.5.9, during the month January/May/June 2017 following standard protocols and methods
of CPCB for determinants like PM10, PM2.5, SO2, NOx, CO and analyzed by NABL-QCI
approved laboratory. These results were compared with NAAQM standards. From the
results it may be observed that PM 10 varied between 50.8 and 67.0 µg/m3. PM2.5 varied
between 13.0 and 26.0 µg/m3. It may be noted that PM10 & PM2.5 are in the ratio of 2:1.
SO2 values varied between BDL(DL:8.0 µg/m3) and 12.1 µg/m3. NOx values varied
between 14.3 & 21.8 µg/m3. . CO values are BDL(DL:1.1 mg/m3). It is evident
from the results that all parameters are within the National Standards showing acceptable
quality of ambient air
46. The maximum Noise levels during day time (L day) is 60.5 dB (A). The Maximum night
time value (Lnight) is 51.0 dB (A). Noise levels for all the locations were found to be
below the limits as compared with prescribed limits for Residential area. The noise levels
are more in the location near pamani regulator of Adappar river and mangudi regulator of
Panavaiyar river due to the heavy vehicular movement at the highway and it is the centre
for both the State High ways. But all the values are found to be within the limits.
47. The analysis results for the ground water (GW) and surface water (SW) samples from the
rivers and adjacent corridor areas are given in the Table 3.5.18 – Table 3.5.22. As seen
from the above tables, the pH value of the groundwater samples ranges between 6.89 and
8.04. The total dissolved solids of the GW sample in all the locations ranges between 298
and 2676 mg/l. The values of Turbidity of GW sample in all the locations were in the range
of 2.3 and BDL (DL:1.0 NTU).
48. During execution, the Environmental Monitoring Plan followed by the contractors are
being monitored by the PMU, PIUs and the Environmental Specialist.. The Environmental
Monitoring compliance of is presented in Table.3.5.22.

4. Any other Environmental Aspects, Impacts observed during Implementation which were
not covered earlier
49. As discussed earlier, environmental issues identified through initial environmental
examination (IEE) are manageable and a range of proven mitigation strategies exist to
address them. The IEE has assessed all potential environmental impacts associated with the
project due to location, design, construction and operation. There are no environmental
impacts which are significant or complex or which need an in-depth study to assess the
impact or to develop mitigation measures. No specific problem was noticed during the
period under report.
50. Though the mitigation measures suggested in the EMP are being implemented through the
contract provisions, proper documentation is lagging. The documentation of EMP
implementation at contractor’s level will be streamlined with the introduction of checklist
system and providing regular trainings. The streamlined functioning will improve the
monitoring system and ensure effective implementation of EMP.
5. Details of Grievance Redress Committee and complaints received from public and actions
taken thereof to resolve
51. The Project Grievance Redress Mechanism has been initiated and made responsible, for
handling public complaints regarding Environmental related matters. The format for the
Environmental Safeguards- Complaint Register to be maintained at PIU/PMU level along
with the Sample grievance form is in place and necessary instructions regarding the same
were shared with PMU and with PIUs through PMU. vide PMU Ltr No .DB/F-11/2016/
dated: 31-08-2016 for the GRM including the relevant forms. No complaint received so
far. All public complaints will be subjected to enter into the Complaints Register. The
contractor will promptly investigate and review Environmental complaints related with the
construction works and adopt appropriate corrective actions to arrest or mitigate the cause
of the complaints. The complaint register will be placed at a convenient place, easily
accessible by the public.
71
52. Continuous consultation and information dissemination is recommended to avoid any
misinformation about the project and in particular about the construction activities. The
nominated environment officer of PMU/PIU will act as single contact point under first tier
GRM. A complaint register will be maintained at PMU/PIU level with details of
complaints lodged, date of personal hearing, action taken and date of communication sent
to complainant. The WRD and contractor will resolve minor complaints such as
disturbances due to construction activity immediately.
53. WRD will maintain a log of complaints made. When a stakeholder raises an issue with the
PMU or PIU every attempt will be made to respond speedily, if the PMU or PIU are unable
to find a resolution within three days of receiving the complaint it will be raised to the
second tier. The engineers deputed to oversee environmental monitoring will report to the
Project Director of the PMU. It is proposed that the aggrieved persons first register the
grievances with the AEE/SDO. After receipt of a grievance, the SDO/AEE will take it to
the project level committee he/she will be responsible for taking up the matter during the
next immediate meeting within 10 days of receipt of grievance and initiate measures for
redress. No grievance can be kept pending for more than a month which means the
committee has to meet every month. Implementation of the redress rests with the PMU. At
any stage of the GRM, if the aggrieved party is not satisfied with the decision of the GRC,
they are free to approach a court of law. The GRM will not impede their access to the
country’s legal system. No Environmental safeguards related grievance received so far.
6. Follow-up Actions and Conclusions
54. The monitoring report confirms that the implementation of the ongoing packages of the
project Loan -3394 IND of WRD,PWD Tamilnadu are in process of compliance and have
so far caused no serious negative Environmental impacts. The Corrective Actions for the
shortcomings observed during the field visits have been communicated to all concerned.
Corrective measures for the same have already been initiated by the concerned i.e. by the
Contractors and PMU/PIU authorities. However, Institutional arrangements as prescribed
in the IEE and Loan Covenants are strictly being followed for better monitoring of
Environmental Management Plan.

Sand Mining- As per Tamilnadu Govt. new sand policy, online purchase of sand for construction purposes has been made compulsory by the Tamil Nadu government from July 1,2017 in a move aimed at ensuring a hassle free experience for consumers. Henceforth, both truck owners involved in distribution of sand as well as the general public have to register online for purchasing sand.“From July 1, 2017, the general public and truck owners (who procure and supply sand from quarries) can meet their sand requirements only by booking online. The same is to help the government meet consumers’ demand and ensure adequate supply of sand at lower rates as they can make advance bookings. Further, trucks involved in supplying sand can now receive the same from quarries and other designated spots at specifically alloted time slots, rather than waiting for long hours outside the quarries. The details of project compliance status with sand mining is given under.

There will be possibility for no closure of approved stone quarry since required quantity is much
available. Similarly, new quarries for sand & gravel will be opened with environmental clearance
soon after the closure of the functioning quarries. For earth mining only, the district
administration is being approached for getting clearance to extract earth from borrow area
identified and approved by PMU. In a few reaches, the earth was taken from private quarry duly
approved by mines Department. In general, adequate quantities of all materials available
surrounding the project area.
