Stone quarries threaten Assam's ambitious semiconductor manufacturing hub

Green activists and local organisations have formally petitioned the government over environmental hazards created by stone quarries and crushing units operating within a five-kilometre radius of the Tata Advanced Systems semiconductor plant in Assam. The petition highlights two key concerns: increased flash flooding events and elevated air pollution levels that threaten the facility's operations.

The semiconductor manufacturing plant requires exceptional environmental controls to prevent microscopic dust contamination during the chip-making process. Particulate matter from nearby quarrying and crushing operations poses a significant risk to production quality and yields, according to submissions made to authorities by environmental groups.

The Indian Semiconductor Mission, which oversees the national chip-making initiative, acknowledged the concerns raised about proximity of mining operations to the facility. The matter reflects broader tensions between industrial development and environmental protection in India's push to establish domestic semiconductor manufacturing capacity.

Tata's Assam facility represents a cornerstone of India's strategy to reduce dependence on foreign chip imports and establish a competitive domestic semiconductor industry. However, the plant's viability depends on maintaining stringent operational standards that preclude contamination from external sources.

Authorities have not yet announced corrective measures or regulatory actions regarding the quarries and crushing units flagged by environmental organisations.
