Campaign BackgroundThe Tonawanda Seneca Nation faces an existential threat from the Western New York Science and Technology Advanced Manufacturing Park (STAMP), a proposed industrial “mega site” underwritten by NY state subsidies and facilitated by NY state permits and policy. Despite sustained and forceful opposition from the Nation and its allies, developer Genesee County Economic Development Center (GCEDC) has begun construction of STAMP on 1,260 acres of wetlands, forests, and farmland. STAMP lies adjacent to the Nation’s federally-recognized Reservation Territory, nestled among public protected lands. Tonawanda Senecas and other people from across the Haudenosaunee Confederacy continue to hunt, fish and gather in the Nation’s “Big Woods,” an ecologically rich primary forest. Industrialization at STAMP threatens Haudenosaunee cultural practices as well as the Nation’s treaty-protected rights to clean water and to the free use and enjoyment of its homelands. 


Despite more than 15 years of effort and more than $410 million dollars in NYS subsidies, there are only two fully confirmed tenants at STAMP: Edwards Vacuum, a dry pump vacuum manufacturer and Plug Power, a green-hydrogen manufacturer which suspended construction in 2023 and may never resume. The Nation recently succeeded in forcing GCEDC to rescind approvals for a planned 900,000 square foot data center at the site. While minimal infrastructure has been built, massive environmental harms have already occurred. STAMP constitutes a profound environmental injustice for Nation citizens


STAMP violates New York’s historic Climate Leadership & Community Protection Act (CLCPA), which should safeguard against building polluting facilities near communities such as the Tonawanda Seneca Nation that already experience disproportionate pollution burdens. While minimal infrastructure has been built on the site, massive environmental harms have already occurred. STAMP is a profound environmental injustice for Nation citizens and their neighbors.

We still have the power to stop this disaster: to protect our woods and waters and taxpayer dollars. NOW is the time for us all to Rethink STAMP. Let’s tell the site’s biggest backer, Governor Kathy Hochul: No new NYS funds or permits to STAMP!

Satellite map of the STAMP site and surrounding protected lands. STAMP is an irregular block of land outlined in red in the center. To the left (west) is a beige block about five times the size covering Tonawanda Seneca Nation. Above (north) of that is a green area covering Tonawanda Wildlife Management Area. To the right (east) is Iroquois National Wildlife Refuge, also in green, followed by Oak Orchard Wildlife Management Area, in another shade of green. To the east of the STAMP site is the much smaller John White Wildlife Management Area.
