The Core Group constituted by the MoEF to look into environmental aspects of minor mineral mining recommended that:
1) States must make mining plans mandatory for minor minerals as they are for major minerals.
2) Mining plans should comprehensively address all environmental issues and ensure long term sustainable use of resources.
3) Aspects of mine reclamation, rehabilitation, and closure must be incorporated into rules for minor mineral mining.
4) River bed mining needs regulation and stipulated mining zones to enable monitoring and safeguarding of the environment.
