EIA screening (Environmental Clearance category)

size ≥ cutoff_A → A (or B1 for buildings / river valley); cutoff_B1 ≤ size < cutoff_A → B1 (or B2); below → B2 or exempt

Each sized sector reads its cut-offs from the factor table (with built-in defaults if a value is missing). Fixed sectors (nuclear, refineries, airports, TSDF, oil & gas, integrated steel) are always Category A; process industries are always B1.

• cutoff_A
  Category A cut-off per sectorValue depends on the activity, sector or product chosen; each comes from the factor table with its source.
