Dilution of norms for quarries irks Greens

In a decision that has raised the hackles of regulatory experts and environmental activists, the State Environment Impact Assessment Authority (SEIAA) has cut the minimum distance for quarries from forestland by half, to 50 metres.
The 87th meeting of SEIAA in January took the decision to dilute the distance regulation after a detailed discussion on the report of a sub committee which studied the environmental impact caused by quarrying adjacent to forest areas. The meeting observed that a large number of quarries were operating in the forest boundary without environmental clearance from the SEIAA or district level EIA authorities.
The authority chaired by H. Nagesh Prabhu verified available documents and found that neither the Union Ministry of Environment, Forests and Climate Change nor any State EIA authority had fixed a minimum distance for quarries from forest boundary.
Taking the facts into consideration, the meeting decided to impose a minimum distance of 50 m between quarries and forest land. However, it authorised the State Expert Appraisal Committee to recommend higher distance from the forest based on scientific reasons.
Sensitive areas
The decision, however, has been opposed by regulatory experts who caution against diluting the regulations for quarrying in a State like Kerala with large tracts of ecologically sensitive areas.
Former chairman of SEIAA K.P. Joy said the authority had prescribed a distance of 100 m from the forest for mining activity as a safeguard for the protection of the environment.
“The decision on the buffer distance was taken after considering the importance and fragility of the ecosystems of the Western Ghats.
Sub terrain disturbances and tremors caused by mining and the noise and dust from quarries would be catastrophic to not only to big animals like tigers and elephants and huge tropical trees but also small life forms like rodents, birds and snakes,” he said.
“Allowing quarries to operate close to the forest boundary may lead to a spike in the instances of man- animal conflict,” says T.V. Sajeev of the Kerala Forest Research Institute.
“The constant dust and sound from quarries could force animals to leave the forest in larger numbers,” he observes.
“Sound waves travel fast through granite and could destabilise the slopes, enhancing the risk of landslips during rains,” says Dr. Sajeev.
A study conducted by KFRI in 2017 found that there are 79 quarries within one km from protected forests and 1378 close to reserved forests in the State.
