The South Carolina Department of Health and Environmental Control is taking comment until Aug. 28 on an air permit renewal for Santee Cooper’s Jefferies power plant that excises two shut coal-fired boilers from the permit.
This facility currently has two oil-fired boilers for production of electricity. The facility also operates ancillary equipment including coal unloading, and ash handling and disposal equipment.
“With this renewal, the facility wishes to remove the coal fired boilers (IDs 03-04) and the coal handling system (ID 06) from the permit as they are no longer in service,” said a department public notice.
The department said a 2004 consent decree between it, the U.S. Environmental Protection Agency and Santee Cooper, laid out specific requirements and emission limits that would become effective on certain dates or after the start-up of certain equipment. One requirement is system-wide emission limits. System-wide is defined as Winyah Units 1-4, Cross Units 1-4, Grainger Units 1-2, and Jefferies Units 3-4. The requirements and limits have effective dates and/or other triggering events. Since Unit 03 and 04 boilers are being removed from the permit, there are no longer any consent decree requirements for Jefferies.
Santee Cooper (also known as the South Carolina Public Service Authority) in 2012 retired two coal units at the Grainger plant and the two coal units at the Jefferies plant.
