Observer-ReporterHanover Township, Washington County
Prime Data Centers wants about 1.8 million square feet of data centers and a 350 to 450 megawatt gas plant at Starpointe Business Park. The supervisors deciding the case took a developer-paid trip to Chicago while the application was pending.
Starpointe opened in October 2004 as Washington County's largest industrial park, and after an $11.193 million judgment against the county economic development council, almost 900 acres were sold to ALTIAN Development LLC in late 2024. Hanover Township adopted a data center ordinance in March 2026, and Prime filed its conditional use applications in May 2026. The township posted an agenda for a June 18, 2026 conditional use session to discuss Prime's applications, and it rescheduled the July hearing because of a public notice problem. On July 2, Prime flew supervisors to its Elk Grove Village campus. The Aug. 5 hearing drew more than 200 people and ended after party status requests and jurisdiction objections, and it was continued to Aug. 31, when Bryden presented the project. An engineer described the power plant on Sept. 21, a geologist was cross-examined about old gas wells on Sept. 29, and on Oct. 7 Bryden testified about the paid trip.
Update, October 26, 2026. By October 26, 2026, Hanover Township had posted three more Prime Data Centers conditional use hearing dates on its website: October 28, November 10 and November 11, 2026, each at 6 p.m. at the Hanover Volunteer Fire Department.

Observer-ReporterThe engines would sit in sound-dampening packages rated for 65 decibels at 30 feet inside a building with more sound attenuation, according to the design engineer. Residents raised noise, vibration and light pollution at every hearing.
Observer-ReporterResidents' attorneys say DEP records show up to 12 old gas wells on the former strip mine site that could leak combustible gas. Prime's geologist says most of those wells never existed and found one capped well near the site, and a full report will come at the land development stage.
Observer-ReporterBryden says each of the seven buildings would create at least 300 temporary construction jobs, with 40 to 60 permanent jobs once the campus is fully running.
Observer-ReporterPrime says the campus would use a closed-loop cooling system that recycles water to minimize on-site consumption. No water volume has been reported.
Observer-ReporterTactics: Requested party status through its attorney so it can cross-examine witnesses and appeal, citing members who live near the site.
No local resident group with a public website, petition or fundraiser was found for this project as of Oct. 18, 2026.
Attorneys argued the application was incomplete because it lacked a decommissioning plan, that the zoning hearing board must first decide what use a data center most resembles, and that the supervisors lacked jurisdiction over the power plant application. About three dozen people were granted party standing.
Attorneys for nearby residents and the Center for Coalfield Justice; Prime Data Centers LLC and ALTIAN Development LLC · Hearing proceeded on Aug. 31; no ruling on the jurisdiction objection reported. Parties with standing keep the right to appeal the supervisors' decision.In Pennsylvania, the local zoning ordinance sets the route. A conditional use is decided by the elected governing body (supervisors, commissioners or council). A special exception or variance, and an appeal of a zoning officer’s decision, go to the Zoning Hearing Board. Each is a public hearing on a record: affected neighbors can ask for party status, cross-examine witnesses, and appeal. Municipalities can also adopt data center ordinances with enforceable standards.
Know your rights →Organized community opposition is the single most effective check on these projects in Pennsylvania. Show up to hearings, submit comment when it is taken, support legal and expert-witness costs, and press your municipality for a real ordinance. Pennsylvania municipalities cannot simply freeze applications, but a curative amendment under the Planning Code gives them a defined window to fix a defective ordinance.
