SPARTANBURG, S.C. -- A Greer man has been arrested as part of an investigation into the dumping of hazardous chemicals in Upstate sewage treatment systems.

The Herald-Journal of Spartanburg reports that 48-year-old Timothy Howard was arrested Wednesday and charged with perjury and obstruction of justice.

In August, the Department of Health and Environmental Control suspended the license of Howard's company, American Waste Septic Tank Service, after equipment was found to be contaminated with chemicals known as PCBs. Authorities say Howard lied under oath after he was accused of dumping waste into a grease trap.

Howard was released from jail Thursday on a personal recognizance bond. Records listed no attorney for him.

DHEC began investigating earlier this year after PCBs were found in several Spartanburg County sewer districts.
