Gravel pits, quarries and aggregate crushing and processing operations can generate significant amounts of fine particulate matter dust, both from the aggregate processing operations as well as fugitive dust from the internal traffic areas and exposed windblown areas.
Wastewater is generated during mineral processing e.g., stone cutting, wash water, scrubber water, from equipment cooling, from mine dewatering, and from stormwater runoff at mines and processing plants. Note Hard rock mining of metals ores is covered in the Ore Mining Effluent Guidelines, 40 CFR Part 440. Facilities Covered.

Land acquisition, excavation, extraction, crushing, screening and washing equipment are necessary in addition to trucks for hauling the material.
2 12 inch crushed stone mainly used to prevent erosion on roadsides and in drainage ditches, also often laid at the entrance to longterm construction projects. Quarry Process. Quarry process, also known as QP, dense grade aggregate DGA, crusher run and road stone, is a combination of small, 34inchorless crushed stone and stone dust.
A stone quarry typically produces the following products Large size blocks blasted from the quarry face, from approximately 0.5 m 3 approximately 0.36 tonne weight to 1.25 m 3 approximately 56 tonne weight, are called rip rap or rock armour and are used in coastal and river flood defence schemes to shore up sea fronts and river banks.
Processing plant Where rocks from the quarry are taken to be processed into different sizes. The processing plant begins at the primary crusher. Quarry A place where rocks are dug or mined out of the earth. Quarry wall The boundary of the quarry, as viewed from inside the pit. Also, the part of a quarry where blasting takes place.
Natural aggregates are composed of crushed stone and sand and gravel. Igneous, sedimentary, and metamorphic rocks are used to make crushed stone and are extracted by open pit and underground mining techniques. Sand and gravel can be mined by open pit, cut and backfill, or dragline methods.
The 1,911 active operations mined rock from 1,039 crushed stone quarries and 743 construction sand and gravel pits. The 100 largest construction aggregates operations produced 14 percent of the
