Beazer East, Inc

Sabine & Waters, Inc. was hired to assist Beazer East, Inc. at the Former Koppers Wood Treatment Facility in Charleston, SC with local permitting, marsh restoration design and implementation, Natural Resource Damage Assessment (NRDA) negotiation and mitigation design, and permit compliance oversight during construction.

 

The Koppers site is approximately 100 acres in the neck area of Charleston. From 1940 to 1978 Koppers Company operated a wood treatment facility on the site that involved treating poles with creosote. In January 1993, Beazer entered into an Administrative Order of Consent (AOC) with EPA for the performance of a Remedial Investigation/Feasibility Study (RI/FS) at the site. Sabine & Waters, Inc was employed to assist Beazer East and their engineering firm in the cleanup design and construction supervision.

Sabine & Waters, Inc. provided design assistance incorporating the requirements necessary to meet local and state regulatory compliance. Much of the remediation work involved excavation of tidal marsh to remove contaminants. Sabine & Waters, designed the marsh restoration, supervised its construction and monitored survival for three years after installation.

Sabine & Waters, Inc. also designed and located suitable restoration sites to meet the requirements of the NRDA settlement. This effort involved locating impacted tidal areas, designing a remedy that would restore the hydrology and natural functions of the salt marsh, and negotiate landowner access to these areas.
