On June 21, 2017, DHEC's Bureau of Land and Waste Management (BLWM) received an application for an Individual Mine Operating Permit for the proposed RDA Mine. The public comment period for the mine application began on August 7, 2017, and will end on August 10, 2018.

Air Quality

On June 27, 2017, SC DHEC's Bureau of Air Quality (BAQ) received an application for an air quality construction permit for the proposed RDA Mine. An air quality construction permit allows for the construction and start of operation of equipment. The public comment period for the draft air quality permit began on June 20, 2018, and will end on August 10, 2018. The draft air quality construction permit and statement of basis are below:

Water Quality

DHEC issues National Pollutant Discharge Elimination System (NPDES) permits to minimize stormwater runoff and other water discharges that may occur during construction and operation of the facility. On August 4, 2017, DHEC Bureau of Water (BOW) received a Notice of Intent requesting coverage under the existing general NPDES permit for the proposed RDA Mine.
