- Fuel supply agreement with collieries to ensure high grade coal supplies.
- Monitoring measures for ash minimisation, ash emission control, ash utilisation and ash disposal.
- Recycling of water from ash ponds for alternative use.
- Modernisation of sewerage treatment plant.
- Continuous monitoring of air quality in work environments & environment management measures.
Fly Ash Initiatives
- MoEF / GoI has stipulated 100% Utilization of fly ash generated by coal or lignite based thermal power plants.
- KPCL has agreements for lifting of fly ash with bulk end-users, viz., cement manufacturers for 100% evacuation and utilization of fly ash from RTPS and BTPS. KPCL is issuing fly ash free of cost to SSI units as per MoEF stipulation. Fly ash is issued free of cost for the use in the works of National and State Highways and for construction of houses and station buildings.
- Fly ash and pond ash is issued for useful utilization by units manufacturing ash based products like Bricks, Asbestos sheets, Road Embankments, Dams and Dykes.
