The operator of a Montgomery County water treatment facility has been charged with discharging sewage into the Perkiomen Creek over a period of five years, the State Attorney General's Office announced this morning.

The criminal charges allege that Michael Martin of Pennsburg also submitted falsified reports to the Pennsylvania Department of Environmental Protection (DEP).

Attorney General Tom Corbett said in a statement that Martin was the operator of the Green Lane Marlborough Joint Authority waste water treatment plant on Gravel Road in Green Lane.

Investigators alleged that Martin allowed untreated or partially treated sewage to be discharged into Perkiomen Creek periodically between March 2004 through August 2009.

Martin also faked sampling data on the monthly reports to the DEP, officials said.

He is charged with one count each of tampering with public records and unlawful conduct, both third-degree felonies, and one count each of unsworn falsification to authorities and unlawful conduct, second-degree misdemeanors.
