State environmental officials are testing samples taken from 55-gallon drums in a Town of Collins barn to determine if the materials contain hazardous waste.
Sheriff's deputies earlier this week charged Robert Kozma of 5051 Brown Road, with operating a junkyard without a permit.
They said an investigation is under way to determine if Kozma is storing hazardous wastes illegally or dumping materials on the property.
Kozma is due to appear in Town Court July 18 on the junk-yard license charge, according to Assistant District Attorney Eugene Adams. He said abandoned cars, tires, appliances and other wastes were stored on the rural site.
State and county investigators who said they were acting on a tip obtained a search warrant to enter the building and take samples. Results of the sampling are expected in about a month, Adams said.
