What this means
The measure would pause permits and approvals for new data center uses for nine months, with a possible extension of up to six months, making new projects substantially harder to start during that time (moratorium duration and scope). It does not expressly halt existing data center operations, and the pause would end sooner if zoning amendments take effect.

pending · Tyrone TownshipProposes to require zoning approval and annual operating licenses for Class A and B data centers, while prohibiting Class C facilities in Tyrone Township.Tyrone Township Draft Data Center Licensing and Siting Ordinance
What this means
The draft would prohibit Class C data centers and limit Class B facilities to 60 MW, with special-use approval and extensive studies and operating requirements; it also sets a 500-foot setback from residential property and a 150-foot greenbelt (Class C centers prohibited, Class B setbacks and greenbelt). Class A and B facilities could still be built if they meet the rules, but the limits and added costs would make development and operation substantially harder.
Timing
A data-center moratorium was adopted on 2025-12-02 and renewed or extended on 2026-05-19, but the sources do not state an expiration date or ending condition.

Restrictions & requirementsHide restrictions & requirements21
A recorded moratorium on data centers was adopted on December 2, 2025, and extended on May 19, 2026, temporarily restricting data-center proposals while regulations were developed.
Class C data centers are prohibited within Tyrone Township, and operating one is expressly unlawful.
Accessory and Class A data centers are limited to the PIRO-A Research and Office subdistrict and require special-land-use and site-plan approval; Class B data centers are limited to PIRO-B Light Industry and also require those approvals. Class C is listed as not permitted in all PIRO subdistricts.
Class A and Class B data centers must obtain a Township license before beginning operations; operating without a valid license, after expiration, or after revocation is unlawful.
A data-center license may be valid for no more than one year, and an operator must cease operations if renewal is not approved before the prior license expires.
License applications require a nonrefundable fee set by Township Board resolution or the comprehensive fee schedule.
License applications require an approved special-land-use and site plan, inspection reports, outside-agency approvals, and extensive technical materials, including environmental, stormwater, wildlife, fire-safety, hazardous-materials, sound, water, electrical-grid, operations, traffic, construction-schedule, indemnification, and insurance documents.
Applicants must fund a Township escrow account for planner, engineer, attorney, public-hearing, and administrative review costs; the Township may require additional deposits, and review stops if the applicant does not provide additional funds within 14 days.
The Township Board must place a completed license application on its agenda and may deny it for missing outside approvals, noncompliance with Township, county, or state requirements, property or structure violations, or an ordinance violation by the applicant within the previous two years.
Licensees must submit annual updates, including prior-year compliance issues and approval-condition compliance, updated operations, electrical, water, fire-safety, hazardous-materials, sound, and decommissioning information, plus an updated decommissioning-cost estimate and additional bond funding when costs increase.
The Township Board may require mitigation measures as a condition of issuing a new annual license based on impacts identified in the operator's annual update documents.
Class B facilities must meet minimum setbacks of 200 feet from a front lot line or road right-of-way, 500 feet from residentially zoned or used property, and 300 feet from other property; these standards prevail over lesser district setbacks.
Class B facilities must provide a 150-foot perimeter greenbelt, comply with commercial and industrial screening standards, and may be required by the Planning Commission to provide additional landscaping or screening.
Data-center structures and accessory structures may not exceed 40 percent of the facility-boundary site, and Class B facilities may not have outdoor storage of goods, inventory, or equipment.
Class B facilities face building-design requirements intended to prevent large blank walls, including articulation for buildings over 200 feet, ground-floor differentiation, windows or faux windows, enhanced entrances, varied rooflines, and abundant landscaping.
Data centers must limit audible sound to 45 dB(C) at property lines, comply with the Township's noise rules using C-weighted measurements, use approved third-party testing, conduct a pre-construction survey, complete a post-construction survey after 12 months, and conduct annual surveys thereafter. Ground-mounted equipment also may not produce discernible vibration beyond the property line.
Class B facilities using water for cooling must use closed-loop or recycled water unless the applicant demonstrates that an alternative will not affect potable-water resources or sewer systems; water plans may require well-impact analysis, hydrogeological studies, public-utility capacity evidence, and other technical documentation.
A Class B data center may not use more than 60 MW of power and must provide electric-provider verification of grid capacity, identify upgrade costs and responsible parties, and agree to absorb rate increases associated with required upgrades.
Applicants must submit a professional-engineer-prepared decommissioning plan, maintain financial security equal to 125 percent of projected removal costs, review and adjust that guarantee every five years, and use an A+-rated bonding agency if a surety bond is posted.
Electrical generators generally must be located in an enclosed, ventilated building and may be operated for testing only from 9:00 a.m. to 5:00 p.m. Monday through Friday, excluding holidays, unless there is a power outage.
Fuel tanks are limited to 20,000 gallons, one tank per data-center building, must be above ground, must be 100 feet from wells and 500 feet from property lines and rights-of-way, and require full catchment or double-wall containment plus an overfill alarm.
Benefits & exceptionsHide benefits & exceptions8
Data processing and computer centers are permitted by right in all three PIRO subdistricts, subject to the ordinance’s separate classification rules. The table lists data processing/computer centers as permitted uses in PIRO-A, PIRO-B, and PIRO-C.
Accessory data centers and Class A data centers may be developed in PIRO-A through the special-land-use and site-plan process. Accessory facilities are generally limited to 150 kW, while Class A facilities may use up to 1 MW. Accessory Data Center and Class A Data Center are listed as special land uses in PIRO-A.
Class B data centers may be developed in PIRO-B through special-land-use and site-plan approval, with a permitted power range of more than 1 MW up to 60 MW. Class B Data Center is listed as a special land use in PIRO-B.
The Class B definition expressly allows a facility to serve either one business or multiple businesses, enabling both single-tenant and multi-tenant data-center models. A Class B data center offers space to a single business or multiple businesses.
The licensing ordinance creates a defined operating license pathway for Class A and Class B facilities. The Township Board is required to issue a license when the application, inspections, zoning compliance, and other stated requirements are satisfied. The Board shall issue a license upon satisfaction of specified requirements.
A Class B facility using water for cooling may use a system other than closed-loop or recycled water if it demonstrates to the Planning Commission and Township Board that the alternative will not affect potable-water resources or sewer systems. The closed-loop requirement has an exception for a cooling system shown to have no impact.
Data centers may use electrical generators, including for testing during specified weekday daytime hours, and the Planning Commission may approve generators located on the interior of the site instead of inside an enclosed ventilated building. The ordinance permits generator testing and allows an interior-site alternative.
Class B facilities may install above-ground fuel storage tanks of up to 20,000 gallons, with one tank permitted per data-center building, subject to setback, containment, and regulatory requirements. Fuel storage tanks may not exceed 20,000 gallons and one tank is permitted per building.
