PPG continues work on canal remediation project

LAKE CHARLES, La., July 10, 2008 – PPG Industries (NYSE: PPG) continues work on a $10.8 million discharge canal remediation project at its facility here. 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 project was announced in February and includes the remediation of an upper section of the PPG discharge canal, the rerouting of the canal’s discharge point from Bayou d’Inde to the Calcasieu River, and the creation of 15 acres of wetlands adjacent to the Interstate 210 Bridge that will benefit wildlife and fishery habitats.

To reroute the canal’s discharge point, PPG recently began dredging activities below the I-210 Bridge. A dredge barge excavates materials and discharges these materials through a pipeline into an area just north of the ship channel. Approximately 10,000 gallons per minute of water are used to flush the solids through the pipeline.

“At this stage of the project, the plume of water that is part of the dredging process is quite visible,” said Jon Manns, PPG works manager, Lake Charles. “The discharge of the dredge materials from the dredge pipeline under the I-210 Bridge looks like a fountain.”

Manns said that the dredging operation is not harmful to the residents or the environment, and that it will continue for the next several months.

Canal remediation efforts will also involve the stabilization of contaminated sediments using a fabric filled with concrete. Approximately 2,400 linear feet or 50 percent of the canal has been completed to date.

The creation of beneficial wetlands is a key element of the overall project. These wetlands are being created with the dredged materials from the rerouted canal. A local consultant, experienced in the creation of wetlands in South Louisiana, is monitoring the site closely.

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.
