The current project proposes extraction and crushing of up to 25,000 cubic yards of rock as frequently as annually with the total extraction volume not to exceed an approximate 40,370 cubic yards from the quarry. In 1994, the County permitted the rock quarry and allowed extraction of up to 25,000 cubic yards every three years. There were a total of seven extractions with the removal of approximately 42,330 cubic yards of material. There are no proposed changes to the originally permitted operations. Mining activities include extraction of rock from the quarry face, crushing and stockpiling of rock on temporary piles located on the quarry floor. The permit term is 15 years and will expire in May 11, 2024.
