Permits Include Protective Conditions to Avoid and Mitigate Potential Natural Resource Impacts
New York State Department of Environmental Conservation (DEC) Commissioner Amanda Lefton today announced the issuance of nine environmental permits that help support the start of construction for the transformative Micron New York Semiconductor Manufacturing LLC project in the town of Clay, Onondaga County. DEC’s transparent and thorough reviews of Micron’s applications include public review and comment to ensure protection of public health and the environment.
“The permits finalized today provide important requirements for the protection of freshwater wetlands, water quality, and endangered and threatened species by minimizing impacts to natural areas, enhancing research, and ensuring conservation through monitoring while also preserving responsible economic development for Central New York,” Commissioner Lefton said. “I thank the DEC teams who worked across multiple offices and regulatory jurisdictions for their valuable insight and appreciate those who continue to engage with DEC in the permitting process.”
The permits issued today include freshwater wetlands, endangered and threatened species, and six mitigation projects to create, restore, and enhance wetlands, in addition to a Clean Water Act Section 401 Water Quality Certificate. In July, DEC offered a public comment period that closed in September and two virtual public comment hearings in August.
In addition, a draft Air Title V permit is currently available for public comment until Wednesday, Dec. 17, 2025. DEC also held two virtual public comment hearings on the proposed air permit application earlier this week. Additional comment periods are open on connected actions that would extend water and gas service to the Micron main campus. Details about public comment periods and additional permitting updates can be found on DEC’s Micron New York Semiconductor Manufacturing LLC webpage. Final permitting materials will be posted as soon as practicable.
