AMERICAN CREOSOTE DERIDDER

OLEM/OSRTI
Washington, DC 20460

July 2017

DeRidder, Louisiana

Beauregard Parish

(?) Site Location:

The American Creosote DeRidder site is a 55-acre tract of land owned by Central Manufacturing Company (CMC)
located south of the city of DeRidder, Beauregard Parish, Louisiana.

Site History:

Historical timber treatment operations at the American Creosote DeRidder site have resulted in contamination by
creosote related compounds. The Shreveport Creosoting Company operated a creosote timber treatment facility from
the early 1920s to approximately 1945 on a parcel of land south of DeRidder, creosote operations were relocated from
this tract of land in the mid-1940s, although other wood treatment procedures are reported to have continued until
approximately 1957. From 1957 to 1992 the property remained dormant until its purchase by CMC in September
1992.

I Site Contamination/Contaminants:

Soil, sediment and surface water are contaminated with waste from previous timber treatment activities including
liquid pitch oil, tar oil and coal tar solutions. Wastes were collected in on-site concrete vats and pits. Soil, sediment
and surface water at the site include numerous polycyclic aromatic hydrocarbons (PAHs), total petroleum
hydrocarbons (TPHs), and metals. A drip area, creosote processing basin area, waste pit and washout area were located
on-site, and used during operations in the wood preserving pressure treatment process.
