degradation is a fall out of industrialisation. Coupled with the massive
growth in population, environmental degradation has become an attendant
evil. Air and water quality has gone down, noise levels have increased and

the years, has successfully converted the spoils (reclaimed areas)into
agricultural fields through modern techniques.The dumped soil ,after
excavation, is improved through modern techniques.It is improved in stages
to match its original fertility and the agricultural operations are carried
out by adding nutrients like organic, inorganic and bio-fertilisers in
suitable measures to make the soil suitable for cultivation.
afforestration efforts are conceived as a measure for preserving ecological
balance and for increased stability of the soil.under the afforestration
schemes, so far 166.25 lakhs saplings were planted in Neyveli township and
To offset the effects of denuded vegetation, NLC initially started
afforestation. Tree species like eucalyptus, accacia, babul, bamboo, vagai
and neem have been planted on the dumps and other vacant areas. On the
slopes also vegetation was planted to check soil erosion. Experiments were
done to reclaim 25 acres of mined and backfilled land for agricultural use.
Accordingly, top soil was transported and spread to a thickness of around
one foot. In order to improve the soil structure and fertility, certain
ingredients such as sawdust, flyash, gypsum, farmyard manure and mud were
Trials in reclamation was also carried out successfully without application
of top soil. NLC has shown that application of farmyard manure, mud,
biodigested cowdung slurry, composted coirpith or vermicompost at 20 tonnes
per hectare, together with the recommended fertilizer, lignite, flyash,
gypsum and humic acid had a profound influence on the physiochemical
properties of the spoil. This provided an ideal condition for growing paddy,
pulses, sugarcane and banana. Vegetable gardens were also developed in which
brinjal, ladies finger, cauliflower and chillies were grown. The yield of
paddy was 6.5 tonnes per hectare and that of banana 25.0, sugarcane 115.0
and maize 8.0 tonnes per hectare respectively.
Land reclamation has also been well programmed. Every year the area made
available through backfilling will be taken up for agriculture, horticulture
and forestry programmes in equal proportions. A tie-up arrangement has been
proposed for the cultivation of sugar cane every year in 100 acres of mines
spoils and supplying the produce to sugar mills. Growing of grass on the
slopes has added to their stability besides giving them an aesthetic look.
The abandoned ash pond at NLC was causing air pollution in the windy season.
Lime, farmyard manure, red earth, mud, bio-fertilizer and tank silt were
applied in the excavated pits in recommended dosage. Plant species like neem,
casurina, cashew, teak, white babul and tamarind trees were planted. All the
species survived. Casurina, neem and white babul were found to have a better
Air Quality Monitoring
There is a well organised network at NLC conducting air quality monitoring.
Six sampling stations have been selected in confirmity with local site
suitability and to cover major population pockets in the vicinity. The air
quality is being monitored simultaneously at these locations on every
alternate day for 24 hours. The air quality data is sent to the Tamil Nadu
Pollution Control Board and the Ministry of Environment and Forests on a
quarterly basis. NLC is among the very few industries in the country to
conduct ambient air quality monitoring exactly as per the guidelines given
in emission regulations.
Noise level is muffled within the threshold limits by use of silencers, ear
protection devices, proper lubrication and greasing of machinery. The tall
trees grown on the periphery of the mines and the township attenuate the
in Township and Industrial Units
NLC has implemented an afforestation programme both in the township and
industrial area to cover all the wastelands. Under the scheme, over one lakh
sixty thousand saplings were planted till March 1997. Different species of
plants such as eucalyptus, leucena leucocephala, bamboo, accacia,
auriculiformis and casurina have been planted. The dreary and parched
atmosphere of Neyveli now looks lush green everywhere. The plantation helps
control air pollution, acts as a wind barrier, prevents soil erosion,
retains moisture level and enhances the nutrition level of the soil.
Some medicinally important plants have also been found to grow as
undergrowth in the afforested area. Besides, the plantation generates 50,000
mandays every year for the landless labourers and helps in the
socio-economic development of the villages nearby. Intensive afforestation
has not only helped in maintaining ecological balance in Neyveli and
surrounding areas but has also earned a lot of revenue for NLC. The sale of
eucalyptus pulpwood has earned it a revenue of Rs. 136.62 lakh. Eucalyptus
cuttings during 1995-96 and 1996-97 yielded a revenue of Rs. 41.25 lakh and
83.01 lakh respectively. Cashew plantation works have shown an increasing
trend in revenue earnings. Sale earnings amounted to Rs. 41 lakh in the last
four years. The vegetation cover of the township is so dense that only the
top of a church is visible from the heights of the thermal power stations.
Lakes and ponds have been formed in the afforested areas and a picnic spot
created with boating facilites. Thanks to all these, Neyveli has also become
a bird sanctuary now attracting hundreds of species round the year. NLC is
maintaining 20 public gardens, four public parks and 10 traffic islands with
aesthetic lawns and vegetation.
NLC's efforts in maintaining environment and ecology enabled it to bag the
Indira Priadarshini Vrikshamitra Award - 1986, FICCI Award for Environment
Preservation and Pollution Control- 1987, and K.P.Goenka Memorial award for
Environmental Care - 1986. NLC's futuristic vision is to be in the vanguard
among the contributors to the community and the nation by developing and
utilising industrial and human resource to the optimum.
