Suffolk County District Attorney Raymond A. Tierney has announced that Giampiero Cali, 48, from Farmingville, has pleaded guilty to charges of Endangering the Public Health, Safety or the Environment in the First Degree and other related offenses. These charges stem from his involvement in dumping hazardous materials originating from a Brooklyn demolition site into Suffolk County.
“Suffolk is no one’s dump site,” stated District Attorney Tierney. “This is our home. I will continue to devote substantial resources to ensure we have the purest land, air, and water, not only for our enjoyment but for our health and safety.”
Cali, who is a principal at Truck Tec Material Corporation, was found guilty of intentionally disposing of acutely hazardous materials as construction and demolition debris at CMM Landscape Supply in Yaphank on April 12, 2024. He deceived CMM staff by claiming his load was "clean fill," which enabled him to dump it at their facility unlawfully.
Two days prior to this incident, on April 10, 2024, Truck Tec Material Corporation had entered a corporate plea directing them to dispose of the same payload at Posillico Materials. This facility is authorized by the New York State Department of Environmental Conservation to accept such material. Cali attempted to cover up his illegal disposal by creating a "substitute" payload that he tried unsuccessfully to pass off as the original load.
The investigation began in February 2024 when Cali instructed a Truck Tec employee to collect demolition debris from Brooklyn using a company truck and dispose of it at a residential site in Medford. Upon discovering that the payload was not clean fill, the employee informed Cali via text message. Cali then directed him to take smaller pieces mixed with other fill material to disguise its characteristics.
The New York City Business Integrity Commission flagged the departing vehicle and notified Suffolk County's Biological, Environmental, and Animal Safety Team (BEAST) detectives about potential illegal dumping activities. BEAST detectives intercepted the truck just before it could unload onto residential property in Medford.
The truck was impounded due to safety violations and suspicion of contaminated fill. Laboratory analysis confirmed cobalt presence—a hazardous substance under state regulations—in the fill material. Truck Tec eventually pleaded guilty through corporate counsel for attempted unlawful disposal of solid waste and received a $15,000 fine along with instructions for compliance reporting regarding safe disposal practices.
Cali initially arranged proper disposal with Posillico but later diverted plans by taking contaminated material back to CMM while falsely representing it as clean fill for reduced disposal fees—leading authorities astray until further comparative analysis exposed his fraudulent actions during subsequent confrontations by BEAST investigators.
