DALLAS — The Department of Justice, Environmental Protection Agency (EPA) and the state of Louisiana announced that Houston-based CCS (USA) Inc. and several of its operating subsidiaries will pay a $2.5 million civil penalty relating to operations at its Shreveport, La., industrial wastewater treatment plant, according to a press release.

The settlement will resolve violations of the Clean Water Act, the Clean Air Act and the hazardous waste law known as RCRA.

Inspections by EPA and the Louisiana Department of Environmental Quality led to the discovery of these violations and others, including unpermitted storage and improper handling of hazardous wastes and sludge, unpermitted storm water discharges and noncompliance with Clean Air Act requirements for benzene-containing wastes, stated the release.

After discovering these violations, CCS ceased wastewater treatment operations at the facility. Under EPA supervision, CCS removed the hazardous wastes illegally stored there, noted the release.

The $2.5 million civil penalty will be split evenly between the United States and state of Louisiana.
