Tucker Printers of Henrietta has pleaded guilty to improper disposal of industrial waste and agreed to pay a $318,000 fine.
The company, located on Middle Road, had been dumping industrial waste into its septic system for years, the state Department of Environmental Conservation said in a news release Wednesday.
The DEC discovered the illegal discharge into Tucker Printer's on-site septic system, along with other hazardous-waste storage violations, during an inspection in 2012, the news release said.
What the DEC described as extensive sampling of groundwater under the property found no evidence of lasting environmental damage. An agency spokesman said the company discharged phosphorus compounds and volatile organics into its septic system — a type of disposal system most typically used for sanitary waste that can allow liquids to enter the local groundwater.
The company entered a guilty plea in Henrietta Town Court on Tuesday night to multiple counts of unlawful disposal of industrial wastes and agreed to pay the fine, the DEC said. It also will reimburse the agency $3,700 for the cost of sampling.
Separately, the company signed a consent order agreeing to resolve waste-storage violations and paid another penalty of $30,500. Industrial wastes are now being disposed of in a lawful way, the DEC said.
The company did not immediately return a call for comment.
