About Sa 6b S.r.

The primary purpose of Sa 6b S.r. 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 Suwanne River near Ellaville.

The dam stands 27 feet tall and stretches 9,000 feet across, creates a reservoir covering 225 acres, has a maximum storage capacity of 4,200 acre-feet, and collects water from a drainage area of 250 square miles. Completed in 1976, the structure is 50 years old.

An emergency action plan is in place for this dam. The most recent inspection on record was 12/23/1998. That was over 27 years ago.
