Suffolk County District Attorney Raymond A. Tierney announced the conviction of Giampiero Cali, 48, from Farmingville, for felony environmental crimes. Cali pleaded guilty to Endangering the Public Health, Safety or the Environment in the First Degree and other related charges. These charges stemmed from his illegal dumping of hazardous materials in Suffolk County originating from a Brooklyn demolition site.

"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, a principal at Truck Tec Material Corporation, was accused of intentionally dumping construction and demolition debris at CMM Landscape Supply in Yaphank on April 12, 2024. He misled CMM staff by claiming his load was "clean fill," which allowed him to dump it there unlawfully.

The situation was further complicated by a corporate plea involving Truck Tec Material Corporation two days earlier on April 10, 2024. Cali had been instructed to dispose of this payload at Posillico Materials, an authorized facility. He attempted to cover up his actions by creating a "substitute" payload to deceive both environmental crime investigators and Posillico.

The investigation began in February 2024 when Cali directed an employee to transport demolition debris from Brooklyn to Medford using a Truck Tec-registered commercial dump truck. The employee informed Cali that the payload was not clean fill. Cali instructed him to disguise it by mixing it with other materials before loading it.

The vehicle carrying the debris was flagged by the New York City Business Integrity Commission and monitored by Suffolk County District Attorney’s Biological, Environmental, and Animal Safety Team (BEAST). Detectives intercepted the vehicle as it attempted illegal dumping in Medford.

The truck was impounded due to safety violations and suspected contamination. Laboratory analysis confirmed cobalt presence—a hazardous substance under New York State regulations. Following this discovery, Truck Tec took a corporate plea for attempted unlawful disposal of solid waste resulting in a $15,000 fine and compliance directives.

Despite initial arrangements with Posillico Materials for proper disposal after securing permissions for truck release, Cali diverted the contaminated payload to CMM instead. He falsely declared it as "clean fill," benefiting from reduced disposal costs.

When confronted by BEAST investigators later on, Cali fabricated paperwork with Posillico and tried passing off another load as the contaminated one originally intercepted. His deception unraveled following comparative fill analysis conducted by investigators.
