Sa 4 S.c.

About Sa 4 S.c.

The primary purpose of Sa 4 S.c. is tailings. Tailings dams contain waste material from mining operations — typically a slurry of finely ground rock left over after valuable minerals have been extracted. These structures require ongoing monitoring because tailings can contain heavy metals and other contaminants. The dam is owned by Pcs Phosphate (private). It impounds the Swift Creek near White Springs.

The dam stands 31 feet tall and stretches 27,368 feet across, creates a reservoir covering 1,418 acres, has a maximum storage capacity of 34,000 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1986, the structure is 40 years old.

This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. An emergency action plan is in place for this dam. The most recent inspection on record was 09/07/2005. That was over 20 years ago.
