A. |
Air Pollution |
Air pollution control measures adopted by NCL are :
|
|
Drills are provided with dust extractors to control dust at source. |
|
|
Approach roads to mines and service roads are provided with black topping to reduce dust generation. |
|
|
Water sprinklers of fixed type and mobile type are deployed for dust suppression on haul roads. |
|
|
Automatic sprinklers, actuated through sensors, are installed at receiving pits. |
|
|
Fixed sprinklers are provided and operated through valve control system at coal bunkers, transfer points and loading points. |
|
|
Dust cyclones are provided at bottom of receiving pits of crusher house. |
|
|
Coal Handling Plants (CHP) have been fully enclosed to reduce coal dust emission out side it. |
|
|
Coal is loaded to Merry Go Round (MGR) System through Rapid Loading System in moist form. |
|
|
To despatch by truck, coal is wetted after loading and then covered with tarpaulin. |
|
|
Routine maintenance and periodic over-hauling of Heavy Earth Moving Machineries (HEMM) are carried out to reduce gaseous emission. |
|
|
Thick green belt curtain, in the form of tall plants with broader leaves, have been provided at mine boundaries to arrest air borne dusts. |
|
|
Under Over Burden (OB) dump reclamation plan, non-active OB dumps are provided with vegetative covers to prevent dust emission. |
|
|
Provision made for dust proof cabins in HEMM and dust masks to employees exposed to dust. |
|
|
Fire hydrant system installed at CHPs, Coal Dumps, etc. |
|
Water Pollution |
Water pollution control measures adopted by NCL :
Sewage Treatment Plant (STP):
Domestic STPs have been constructed in the township with activated sludge process. Plant contains aeration units for oxidation, clarifiers for removal of suspended solids, sludge drying beds, grit removal facilities, sewer lines, manholes, pump houses, control room, etc. Treated water is taken for reuse in tree plantation, horticulture, construction activities. Dried sludge is a valuable manure for tree plantation and horticulture works.
Effluent Treatment Plant (ETP):
Integrated Industrial ETPs are designed for average discharge from mines, workshops and CHPs The plant contains traps for recovery of oil & grease, clarifiers for removal of suspended solids, flush mixers for chemical dosing, sludge drying beds and pumping arrangements. Treated water is reused for tanker filling, sprinklers, etc. Dried sludge are buried in lined pits.
Silt Arrestors:
Substantial amount of silts are carried along with run off water. Catch drains with silt arrestors are provided in mines area. Those are cleaned at regular intervals. Check dams and siltation ponds are provided to arrest silt flowing into the watercourse. Gabions (loose boulders packed in wire crates) are provided at toe of the active dumps and across the water course with filter pad to stop silt escape into water body.
Oil Recovery:
Floating oils recovered from traps are collected in drums and then stored on a raised paved area having drains to collect back spillages. Permission has been obtained from SPCB for handling waste oils. Oils in drums are sold to the distillation units having requisite license through Metal Scrap Trading Corporation (MSTC), a Govt. of India undertaking, by way of press advertisement.

Noise & Ground Vibration Control Measures |
Noise Pollution Control measures adopted by NCL:
|
|
Blasting operations are carried out between 1200 to 1500 hrs being lean period for project work. |
|
|
Muff and/ plugs for ears are provided to employees under effect of noise. |
|
|
Curtain plantations are provided at mine boundaries. |
|
|
Routine maintenance of all equipment is done to control noise and vibration. |
D) Technical & Biological Reclamation of External OB Dumps of Opencast Mines:
Vegetative covers over bare OB dumps have been provided in major projects. It ensures stability to dump slopes. The dumps have been reclaimed by constructing proper benching and providing reinforced grass-mat covers, gabions and drains. The slope surface has been covered with mixture of grass-seeds, agricultural soil and manure laid in coir/ hay/ straw / geo-textile-mat. The plantation of trees, shrubs and grass has been done profusely on crowns of dumps, ring bunds, dykes, recess, slopes, etc to ensure thick biological growth. For maintaining vegetative cover, water sprinklers have also been deployed at specific points.
Quality Policy of NCL
We are committed to,
· Assured quality of our coal supplies,
· Continual improvement in system functioning,
