Haile Gold Mine - Air Quality Permit

Haile Gold Mine (HGM) is currently permitted under Title V air operating permit 1460-0070 to operate a gold mine in compliance with state and federal air quality regulations. Operations include open pit mining of gold containing ore and an ore processing plant, where physical and chemical separation techniques are used to extract gold and silver.      

In June 2019, DHEC’s BLWM received an application from HGM to substantially modify its existing mine operating permit. Review of the application is currently on-going. More information about the proposed mining modification project can be found on DHEC's Haile Gold Mine – Mine Operating Permit webpage. On August 29, 2022, BAQ received an air construction permit application to increase ore throughput related to the mining expansion. As part of this construction project, the facility will be establishing a federally enforceable limit to avoid Prevention of Significant Deterioration (PSD) of less than 250.0 tons per year of Particulate Matter (PM). The Department made a department decision to issue the construction permit on December 28, 2022.
