2.0 Site Status Summary

The Green Cove Springs, FL-located plant has operated as Associated Minerals, Titanium Enterprises, and RGC Minerals Sands and currently as Iluka Resources, Inc. The plant processed heavily mineralized sands for the purpose of extracting specific products. The products included, but are limited to, ilminite, rutlite, zircon and leucozene. The host sand contained naturally occurring radioactive components (thorium and some uranium) which in finite portions of the process were temporarily increased to >0.05% by weight. During April 2009, production ceased and the decommissioning plan was submitted August 2009.

The electrostatic and wet process plant was first licensed by the Florida Bureau of Radiation Control for the processing and disposal of technically-enhanced concentrations of naturally-occurring radioactive materials (TENORM) in the 1994. The specific license included specific areas and equipment within the plant where materials were temporarily concentrated. TENORM was found in actionable concentrations only in the product dry mill and its attached conveyer and dryer systems. After the products were removed, the non-product materials were slurried back together (diluted) and pumped back to the mining impoundment area.

Dismantling, surveying and cleaning (if necessary) and removal of process equipment are in progress. Demolition of all plant structures except a few ancillary buildings will follow. Additional phased activities are planned toward termination and release.
