PPG to begin $10.8 million remediation project in Lake Charles

Date: 22 February 2008

PPG Industries (NYSE:PPG) will begin work on the next phase of a project to remediate and re-route the water discharge canal at its facility here.

Soon, the public will see equipment working in the marshy area beneath the I-210 bridge,” said Jon Manns, PPG Lake Charles works manager. “This project is a continuation of our work to remediate the 60-year-old canal.” PPG uses the canal to control rainwater runoff and to discharge its treated cooling and process water.The water is treated to meet Louisiana Department of Environmental Quality (LDEQ) and U.S. Environmental Protection Agency (EPA) standards.

The one-year $10.8 million project will include work on the upper section of the canal. PPG’s contractor, Remedial Construction Services, LP, will stabilize sediments containing low levels of chlorinated hydrocarbons and metals. These sediments will be contained in place through the use of a fabric material filled with concrete. This process will prevent movement of the sediment in the future.

The project will also involve re-routing the canal’s discharge point from Bayou d’Inde to the Calcasieu River. Manns said this work will simplify future remediation work on the lower canal.

He added that the project will benefit wildlife and fishery habitats in the area by creating approximately 15 acres of wetlands adjacent to the Interstate 210 bridge.

“This is another sign of progress for the Calcasieu Estuary," said DEQ Assistant Secretary Lou Buatt. "As a DEQ employee who has worked on Calcasieu issues for many years, it's encouraging to see industry take matters into their own hands and work for the betterment of the environment. We look forward to more positive announcements concerning the estuary in the near future.”

All necessary local, state and federal permits for this project have been received. The project is expected to be completed by the end of 2008.
