Inspectors monitor Saint Gobain demolition for hazardous waste risks

On April 15, 2025, the New Hampshire Environmental Services Department convened a meeting to discuss ongoing inspections related to the demolition of a facility owned by Saint Gobain. A key focus of the meeting was the department's commitment to monitoring potential environmental risks associated with the demolition process.

Mike, a representative from the department, emphasized the importance of on-site inspections to ensure safety and compliance during the demolition. He noted that regular visits by inspectors, including staff member Tammy Caligandez, are crucial for overseeing the progress and addressing any hazardous waste concerns. Caligandez has been actively involved in monitoring the decommissioning of a hazardous waste storage building that was previously used by the company.

The discussion also touched on the fate of a Regenerative Thermal Oxidizer (RTO), a device that had been part of the facility's operations. While attempts were made to sell the RTO, it appears that it was ultimately disassembled for scrap due to a lack of buyers. This raises questions about the management of such equipment and its environmental implications.

Another point of concern raised during the meeting was the handling of scrap materials that may be contaminated with PFAS (per- and polyfluoroalkyl substances). A participant inquired whether recipients of these materials are informed about their contamination status. The response indicated uncertainty about the notification process, highlighting a potential gap in communication regarding hazardous materials.

Overall, the meeting underscored the Environmental Services Department's proactive approach to monitoring environmental risks during the demolition of the Saint Gobain facility. As the department continues its inspections, the implications of hazardous waste management and communication practices remain critical issues for the community and the environment. Further follow-up on the RTO's disposal and the notification process for contaminated materials may be necessary to ensure public safety and environmental protection.
