Crushed stone and gravel operations remove material from the ground and process it by conveying, crushing, screening, washing and drying. NSSGA members work diligently to reduce dust emissions throughout these processes, installing dust suppression and collection equipment at their facilities. NSSGA members produce limestone, which is used to reduce harmful emissions from power plants and other industrial sources.
