Aggregate industry products are commonly used in making asphalt pavements for transportation purposes or in nuclear family homes or even in business houses. Our water treatment plants or sewer treatment plants are constructed with concrete and aggregate that is used as a filter in both these plants.
How are Aggregate products produced?
The process of stone quarrying involves breaking of stones into diverse shapes and sizes for building purposes. Quarry stone is used in all types of stone creations like the ones ranging from central offices to farm credit foundations. Most easily available natural resources and chief raw materials like sand and gravel are used mostly by the construction industry. After being mined from naturally occurring open deposits, they are then moved for processing. Processing includes: crushing of the material, handling of the material, screening, milling, dust collection, size reduction, conveying, loading or unloading.
The production of aggregate products results in dust emission, which is common to all these operations. “Fugitive Dust” is the term commonly used to describe such emissions. This means that the dust is coming directly from the process to air such as from open screens, conveyors or unpaved roads.
Why is DEC permit required?
All the equipments that are required in processing at quarry stone or sand and gravel mines and have a maximum rated capacity more than 25 tons of minerals per hour, require Department of Environmental Conservation (DEC) permit. Mobile crushers with maximum rated capacities more than 150 tons per hour for non-metallic minerals’ processing operations, like quarry stone, sand and gravel also require DEC permit. Exemption is granted for equipments installed before Aug 31, 1983 used for operations like wet conveying, washing and separating.
