Anti-Data Center Policies
Somerset County’s enacted ordinance requires data centers to stay 1,000 feet from homes and sensitive areas, limits water cooling, and mandates studies, reporting, and full-cost decommissioning security. It makes projects harder but does not ban them outright.
current law · County measureEstablishes binding county planning requirements for data centers and associated facilities in Somerset County, including buildings, substations, generators, cooling systems, utility infrastructure, and battery storage; it was adopted on October 20, 2026, and is effective upon enactment.Pennsylvania Somerset County Data Center Facilities Planning Ordinance (2026)
What this means
The ordinance would make projects much harder through wide setbacks, strict water-cooling limits, and extensive studies and reporting requirements; for example, it requires a 1,000-foot separation from homes or sensitive receptors. It also requires financial security covering the full estimated decommissioning cost, creating a substantial upfront burden even though it does not ban data centers outright.
