In the year 2002, Tuticorin Port Trust appointed NEERI as
consultants for carrying out Rapid & Comprehensive
Environment Impact Assessment Studies along with assessing
Techno-economic viability of the project. The objective of the
study was to obtain Environmental Approvals from the concerned
local, state windows 7 product key, and central government authorities. The terms of
Reference issued by TPT to NEERI comprises of two section viz.
Techno-economic viability & other related to Environment
Impact Assessment as given below:
TOR for Techno-economic viability
of Techno-economic viability of the project
of oceanographic and meterological data
of quantum of capital dredging
of best suited dredging methods, dumping & disposal
out offshore & onshore disposal areas
of quantum of maintenance dredging periodicity &
requirement of onshore facilities for administration
The progress report discussed about the project
setting, baseline environmental conditions in terms of marine,
land and social-economic environments.
Further the report also discussed about the impacts for the
construction and operation phases.
TOR for Environmental Impacts Assessment
- Short listing
of viable routes based on Techno-economical considerations
of present status of coastal water, marine, land, biological
and socio-economic components including parameters of human
of potential impacts on various environmental components due
to activities envisaged during construction and operation
phases of the project
of impacts using various simulation models
of Environmental Impact Statement
of acceptable Channel route for shipping based on
of Environmental Management Plan
of benefits due to ship movements in the operation phase of
quality monitoring programme for construction and operation
a presentation of the EIA Reports to various government
agencies, environment authorities of State Government,
NGOís, MoEF etc.
Subsequently NEERI submitted a progress report to Tuticorin
Port Trust in September 2002 on the works carried out till then.
Observations on this report are as follows:
progress report submitted by NEERI in September 2002
discussed about the present environment status in terms of
marine, land & socio-economic environments, Environment
impacts & Channel alignment and Techno-economic
viability. The study area was the same as considered in IEE.
report presented the environmental setting of the project
area in terms of the island details in Gulf of Mannar,
Hydrography etc. But details pertaining to access & site
surrounding, access to Adamís Bridge etc have not been
present status of the marine environment was established by
drawing on the data collected during the IEE in 1998. The
data presented for the Marine Environment covered the
Physico-chemical and biological status. The assessment
covered the marine water and sediment. The analysis given
for the various marine environmental components is laudable
and confirms the biodiversity richness of the Gulf of Mannar
and Palk Bay.
status of land environment was established by using
satellite imageries by developing false colour composites
using IRC LISS & PAN images. The data was further used
for identifying suitable sited for disposal of dredged
socio-economic environment elaborately discussed about the
profile of the fishing communities located around Gulf of
Mannar and Palk Bay. The profile was arrived at by analysis
of secondary/published data supported with a rapid sample
survey representing 8000-10000 fishermen hailing from
Pamban, Natarajapuram, Ramakrishnapuram, Kothandaramakoil
Nagar and Moonruerupuchattram.
During the random survey, the public perception about the
project was eliciated.
impact associated with the project were discussed in terms
Land acquisition, Rehabilitation & Resettlement, Impacts due
material disposal, Increased Road/Rail Traffic, Socio-economic impacts,
Ecological impacts and Hydrodynamics Aspects.
Analysis of Alternatives ?The various alignment suggested
during various studies were analysed in content of technical,
economical, environmental and social aspects and alignment along
the Adams Bridge has been accordingly finalized.
On finalisation of the alignment, Techno-economic viability
studies were carried out covering traffic, economics and
It is understood that the progress report is basically meant
for finalising the
Channel alignment paving way for further studies.
