AMERICAN CREOSOTE WORKS INC. (WINN PARISH) LOUISIANA EPA ID# LAD000239814 Site ID: 0600317 XIWv75 EPA REGION 6 CONGRESSIONAL DISTRICT 05 Contacts: Michael A. Hebert 214-665-8315 Updated: December 2007 Current Status The long-term phase of the Remedial Action for in-situ biological treatment of contaminated soil and the pumping and treatment of liquid contaminants is ongoing. Currently, on average, over 600,000 gallons of liquids (contaminated ground water and non-aqueous phase liquids or NAPLs) are collected and treated per month, including over 500 gallons of NAPL. The collected NAPL is transported off site to a permitted facility for incineration. Treated ground water is either reinjected as part of the in-situ biological treatment process or discharged to Creosote Branch Creek via permitted outfall. EPA continues to monitor the performance of the remedy to assess its effectiveness in achieving the established remedial objectives. A second Five Year Review of the remedial action was completed on September 19, 2005. The remedy was found to be protective of human health and the environment. EPA has initiated a ground water tracer survey in order to determine specific ground water flow paths. This will aid in maximizing the removal capacity of the ground water recovery system. Benefits The $17 million remedial action boosted local employment during the cleanup by utilizing local labor. The prime contractor also utilized several area vendors. Local vendors were identified during the bid specification stage utilizing the Chamber of Commerce to identify area expertise. The completion of the in-situ bioremediation system has effectively eliminated discharges to Creosote Branch Creek, allowing the stream to recover to natural conditions. EPA is working with the City of Winnfield to transition the site to industrial use. Currently about a third of the site is being reused by a local construction firm.
