Mathura Refinery: Eating away history
As one approaches the city of Agra, one can see the haze that looms over the horizon, providing a
shimmering quality to the old monuments that dot the city of Taj. The haze is killing the Mughal
monuments and ancient temples at an alarming rate. The historical monuments in Agra-Mathura-
Bharatpur region are directly in the line of the deadly Sulphuric dioxide (SO2), which mixes
withwater vapour to form Sulphuric acid (H2SO4) showers.This acid reacts with marble and
sandstone, the main building materials in most of the Mughal monuments and temples, silently
eroding history away. The pollutants emitted by the refinery has also started showing its effects
on flora and fauna of the Bharatpur Bird Sanctuary which was declared a World Heritage Site in
the year 1985. But now for the past few years, the trees in the park have started falling, and
whenever it rains in the region, small ponds have a yellowish layer on it.

ACC cement plant is situated in Nandini, Bhilai, Chhattisgarh state, India, in industrial area. It is
providing quality product and excellent service. It has ISO 14000 certification and ISO 9002
quality system. It continues to promote various environmental performance initiatives in its own
facilities viz. reduce dust emission, create a healthy environment, plantation and also reduce
electricity consumption. It also recognizes the importance of social responsibility as a part of its
overall commitment to sustainable development. Therein, perform the following activities: -
maintain a mini hospital to provide medical services, donations, education and development. The
ACC plantconsists of several units from limestone crushers to packing plants. Crusher unit comes
under the main processing unit.Crusher department is one of the major sources of environmental
pollution. Fugitive dust emission, stack emission and noise have been identified as significant
aspects during activities like receipt of limestone, primary crushing, screening. These significant
aspects are imparting very much impact on the human health like respiratory disorders, hearing
impairment, etc. Thus there arises a need for developing a strategy for reducing the impacts and
this require more attention to be emphasized on the aspects.
Module III

b) What are the initiatives taken by ACC to improve the environmental quality? (3)
€) List the common formal methods used for impact identification and analyses of (2)
significance of impacts.
