Sentinel Data Centers is building a 341,000-square-foot data center along Route 1 on the former Princeton Nurseries property in South Brunswick. The South Brunswick Planning Board has approved the development, while the New Jersey Department of Environmental Protection is still reviewing the company’s request to operate 12 diesel-powered backup generators and store fuel on the site.

Residents and officials in nearby Princeton are raising concerns about diesel emissions, potential effects on two elementary schools, and the risk of fuel contamination reaching local waterways. Princeton’s mayor and council have urged the DEP to deny the permit in its current form, and residents in South Brunswick and surrounding communities can submit public comments before the stated Nov. 9 deadline.
