it discusses various points on the subject of report prepared for developing new project

1. EIA REPORT FOR
NEW PROPOSED
PERIPHERAL ROA
D IN CHENNAI

2. Project description
The Government ofTamil Nadu (GoTN) is promoting
the development
of roads and public transportation as a countermeasure
to traffic
congestion in CMA. Major arterial road network in CMA
are consisted of National Highways No. 5, No. 205, No. 4,
and No. 45 as major radial
roads, and Inner Ring Road (IRR), Chennai Bypass, and
Outer Ring Road
(ORR) as ring roads. Implementation of Chennai
Peripheral Ring Road
(CPRR) Project is expected to contribute to further
expansion of the
Radial-Ring Road Network corresponding to expanding
traffic demand.

3. Chennai has grown as a perfect base in respect of
institutions, information
technology, automobile and hardware manufacturing.
Due to growing
volume of traffic in and around the City, there is an
immediate need for
improvement of infrastructure facilities.
Chennai Peripheral Road is conceptualized to
provide better connectivity
around the city catering future traffic requirements
and provide efficient
commercial transportation by enhancing port
connectivity.This road will
facilitate container movement from southern
districts to Ennore Port.The
Government of Tamil Nadu have accorded
administrative sanction for
forming Peripheral Road connecting Ennore Port and
Mahabalipuram.

6. The alignment for Chennai Peripheral Road is
approved by the Steering
Committee and is finalized by the Principal
Secretary, Highways and
Minor Ports, Government ofTamil Nadu on
09.07.2014.The approved
alignment plan is given in Figure 2.3.The
Peripheral road will starts at
Ennore Port and ends at Poonjeri Junction in
Mahabalipuram.The
proposed road will connect four National
Highways – NH-5, NH-205,
Site Selection

7. The findings of the baseline environmental status on
land (topography,
geology, soil quality, land use pattern), meteorology
(Temperature,
Relative Humidity, rainfall, wind speed, wind rose), air
(ambient air
quality- SPM, PM10, PM2.5, SO2, NOX.), water
(surface water,
groundwater), noise level, ecological environment
(flora & fauna), socio
economic conditions (demographic profile and
households condition)
were presented and interpreted with reference to
environmental
standards.
Baseline Environmental
Data

8. The study area is located in Kanchipuram &
Tiruvallur districts.These
districts has warm and humid climate.The area
experiences warm and
humid summers but cool winters.Winter
season ranges from mid of
November to February and summer season
ranges from March to mid of
June.The climate shows a major shift from the
sultry heat to the
pleasantly cold during winter.The period from
mid of June to September
is the monsoon season followed by the months
October to mid of November.
Meteorology

9. Specific station-wise Ambient Air Quality
(AAQ) data for PM10, PM2.5,
SO2, NOx andCO as recorded during the
period November 2017,
February 2018 & March 2018 are summarized
in Chapter 3.All the
parameters has been analyzed and found within
the standard limit
prescribed by the Central Pollution Control
Board (CPCB).
Air Environment

10. Water
Environment
The development of any region is
contingent on the availability of
sufficient water resources, as
developmental activities require water for
irrigation, domestic and other purposes.
The water resources in the area
broadly fall into SurfaceWater Resource &
GroundWater Resource.

11. The hourly recorded noise level at various
locations in the study area
shows fluctuations because of change in traffic
movement, construction
activities and other man made sources.The
equivalent values of noise
levels are comparable.
The prevailing status of socio-economic aspect
comprises of demographic
profile, Infrastructure, socio- economic condition,
literacy level and
lifestyle, etc.The proposed project will definitely
have some positive
impact on the socio-economic environment of the
people of surrounding
villages experiencing development in the study area.
Noise and Socio-
Economic Environment

12. Ecological resources are among the most
important resources impacted bythe road
projects.The detailed baseline study of the
ecological resources is
essential to estimate the magnitude of
potential impacts and to avoid or
mitigate any loss caused by the proposed
project. In this section baseline
details of the flora and fauna are presented.
There are no endangered
species of flora and fauna present within the
project influence area.
Ecological Environment

13. Mitigation
Measures

14. Speed of vehicles on proposed road has been designed as per natur
e of terrain and nearby habitations.
Road should be designed with good geometry and bottlenecks
should be avoided for smooth flow of traffic.
As per IRC guidelines roughness <2000 mm/km is considered good
for bituminous concrete surface.
All slope and embankments will be turfed as per best engineering
practices to help minimize the dust generation during operation
phase.
Plantation of pollutant adsorbing and fast growing species trees
along the project road,
Ambient air quality monitoring should be carried out during
operation phase for first 3 years. If monitored parameters are above
the prescribed limited, suitable control measures must be taken.
The following mitigation measures will also be taken to mitigate the
dust entrainment and fugitive emissions from the various sources:
Sprinkling of water will control fugitive dust emissions.
Sprinkling of water on the dust prone areas and construction yard.
Regular maintenance of machinery and equipment will be carried
Air Environment

15. Flora and Fauna
• Proper planning for additional cutting of trees.
• Afforestation should be carried with proper management and
• technical planning for successful afforestation programme.
• Existing plantation, along the ROW, should be protected from
• illegal felling of trees.
• Systematic planning prior to the excavation of reverse slope (if any)
• along the project road.
• Fauna
• Plantations of trees along the highways.
• Contingency plan should be developed to minimize contaminations in traffic accidents.
• Water bodies and wetland should be developed along the highways

16. Need for eia
• An Environmental Impact Assessment (EIA) study basically includes:
• Establishment of the present environmental scenario;
• Study of the specific activities related to the project;
• Evaluation of the probable environmental impacts;
• Recommendations of necessary environmental control measures; and
• Preparation of Environmental Management Plan.

18. Environmental clearance of any new project or expansion of existing projects is
now done as per the new notification of the MoEF&CC, Government of India
dated 14th September 2006 and its amendment 2009.The new notification
requires prior environmental clearance of all the projects from competent
central government or state government authorities, as may be the case.The
projects are now classified into category ‘A’ or category ‘B’ projects based on
the spatial extent of potential impacts on human health, natural and man made
resources.The category ‘A’ projects requires prior clearance by the MoEF&CC,
Govt of India while the category ‘B’ projects have to get clearance from the
State level Environment impact assessment authority (SEIAA), constituted by
the central government for this purpose.The environmental clearance
procedure for new projects will require maximum of four stages all of which
may not be applicable to all the projects.

23. Environment
monitoring plan

26. Environment monitoring
program

27. The Environmental Monitoring Programme has been detailed
out in the report.
Successful implementation of the Environmental Monitoring
Program is
contingent on the following:
• The IC is to request the Contractor to commence all the
initial tests for
monitoring (i.e. for Air,Water Quality and Noise Levels) early in
the Contract to
establish 'base' readings (i.e. to assess the existing conditions
prior to effects from
the Construction activities being felt).
• The Independent Engineer is to request the Concessionaire
/ Contractor to submit
for approval a proposed schedule of subsequent periodic tests
to be carried out.
• Monitoring by the Independent Engineer’s Officer of all the
environmental
monitoring tests, and subsequent analysis of results.
