Restoration East LLC, of Baltimore, and Louis J. Helmacy, a Restoration East Co-Owner, were charged on Oct. 28 in Montgomery County Circuit Court with illegally discharging demolition waste into a tributary of Rock Creek. From June 1-10, 2003, the defendants were conducting a hydro-demolition of a concrete floor in a parking garage located in Montgomery County. This activity involved using a high-pressure hose to pulverize the floor and create a concrete slurry. The defendants, however, did not get a discharge permit for this activity from the state, and wastewater from the project allegedly entered the Rock Creek tributary. The case was investigated by the Environmental Crimes Unit of the Maryland Attorney General, the Maryland State Police, the Washington Office of the EPA's Criminal Investigation Division and the U.S. Park Police. It is being prosecuted by the Maryland Attorney General's Office.
