CHAPTER 4
ANTICIPATED ENVIRONMENTAL IMPACTS &
MITIGATION MEASURES Prediction of impacts is the most important step of environmental impact
assessment. Superimposition of predicted impacts over baseline
environmental scenario gives the ultimate environmental scenario. In the
present study, baseline environmental scenario was established through
environmental monitoring data for the period of September-2009 to
November-2009.
4.1 IMPACTS & MEASURES As a first step, the entire process has been divided into a number of smaller
sub activities for construction and operation phases. The probable impacts of
each of these activities on various sectors of environment (such as air, water,
socio-economic environment etc.) have been identified and listed.
The lists various activities of construction phase and their probable impacts on
various sectors of environment. The impacts are classified as long term
impacts and short term impacts.
The impacts are envisaged to be short term impacts, confined to
construction period only (04 months). Further, the magnitude of the impacts is
envisaged to be low, as the site and infrastructural facilities are fully
developed. Mitigation measures for significant impacts are discussed in
respective sections.

4.2 MITIGATION MEASURES 4.2.1 AIR POLLUTION
Cement being a precious product, it is transported with outmost care in
automatic process in covered containers. Any loss in Cement during
transportation will translate into direct financial loss.
Draft EIA report UltraTech Cement Limited – NCMW- SURAT
Royal environment auditing & Consultancy Services, Rajkot 78
Loading and unloading of cement into trucks and silo will be carried out
through air tight ducts/hoses operated by automatic filling machines,
thereby minimizing the possibility of leakage into air environment to
abysmally low.
The company will do regular maintenance of the air ducts, pumps, ship
loaders etc to avoid financial loss due to escape of cement into air.
All the vehicles equipments and storage places used for transportation
and storage of cement are made waterproof to avoid solidification of
cement.
High efficiency bag filters will be used to reduce the dust emission from
transverse points.
4.2.2. NOISE POLLUTION
Provision of earmuffs/head gears to the construction workers.
Ear muffs shall be provided to the concerned personnel during the
operation stage.
It will be ensured that all construction equipment and vehicles are in good
working condition, properly lubricated and maintained to keep noise
within permissible limit.
The ship loader to be maintained properly to ensure best performance
with low level of noise.
4.2.3 WATER POLLUTION
No additional water required and no process waste water generation.
Domestic waste water will be disposed through soak pit system.
1. Storm water channel management:
We have prepared around 700.0 meter length, 1.0 meter width and 1.0
meter of depth, Storm water channel around the plant to avoid the
accumulation of rain water in the plant. Storm water channel prepared in
Draft EIA report UltraTech Cement Limited – NCMW- SURAT
Royal environment auditing & Consultancy Services, Rajkot 79
such way that all surface water flows through storm water channel and
meets the nearby river’s water.
Storm water channel maintenance has been carried out as per planned
schedule. We kept it neat & cleaned by regular cleaning. We ensured
that it should be cleaned before starting of monsoon.
2. Surface run off management:
On the basis of natural ground level we have constructed network of drain
to take away the water flow from surface to drain. Service water is
recalculated through cooling tower for effective utilization without
wastage of water. RO- plant rejected water also utilized in garden.
Septic water connected to water sop-pits and its cleaning has been
carried out regularly.

CHAPTER 5
ENVIRONMENTAL & OCCUPATIONAL
HEALTH MONITORING PROGRAMME Regular monitoring of critical environmental parameters is of immense
importance to assess the status of environment during plant operation.
The monitored data can serve as an indicator for any change in
environmental quality due to operation of the plant with respect to baseline
environmental conditions, so that suitable mitigatory steps could be taken in
time to safeguard the environment.
An environmental monitoring programmer based on the Impact Assessment
for M/s Narmada Cement Limited – Grinding Unit- Magdalla works, shall be
implemented at site. The monitoring plan has been drawn with the following
broad objectives:
1. Assess the changes in environmental conditions, if any, during
operation of the Project.
2. Monitor the effective implementation of mitigatory measures
envisaged for M/s Narmada Cement Ltd- Grinding unit- Magdalla
works. Limited.
3. Warning of any significant deterioration in environmental quality so that
additional mitigatory measures may be planned in advance.
Proposed pollution monitoring programmer is presented in Table 5.1.1. A brief
description of the plan is given in the following sections.

5.1 Monitoring of Environmental Parameters
5.1.1 Meteorology
A full fledged meteorological station shall be set-up at site to generate on-
site meteorological data as per Table 5.1.1
5.1.2 Ambient Air Quality
Ambient air quality shall be monitored at four locations around UltraTech
Cement Limited, Plant presented in Table 5.1
5.1.3 Stack Emissions
Stack emissions shall be monitored for SPM, SO2 and NOx. Provision for stack
monitoring shall be made by UltraTech Cement Limited.
5.1.4 Effluents Quality
There is no process effluents generated during process.
