Scope

Palm Beach Aggregates, Inc. (PBA)  operates a six-acre limestone aggregate mine in Loxahatchee, Florida. Approximately 1,218 acres of this property is referred to as the Lazy F Property, which is located north of State Road 80 and east of the South Florida Water Management District’s (SFWMD) Loxahatchee L-8 Canal.

In 2005 and 2006, PBA placed approximately 8 to 10 feet of hydraulic fill on the Lazy F Property, intending to improve the site for planned residential development. The land improvements have since been completed, and the former agricultural use of the Lazy F site is no longer desirable.

PBA did not own this property in 1995, which was previously utilized for agricultural purposes. Historical documentation and data obtained by BCI indicated that a release of petroleum in 1995 from the excavation and abandonment of three underground petroleum storage tanks located near the southeastern corner of the property had affected the groundwater quality.

In response to correspondence with the Palm Beach County Department of Environmental Resource Management, BCI instituted a plan to close the site in accordance with provisions of Chapter 62-770, FAC. This plan included the replacement of five shallow monitor wells. Analytical results on a set of groundwater samples collected in November 2007 from the new wells indicated that the groundwater quality no longer  appeared to be affected by the historical release of petroleum from the underground storage tanks (USTs).
