PNK Group / Great Stream Commons

Gregg Township (Allenwood), Union County

PNK Group of New York wants to turn an empty 478,000 square foot warehouse at Great Stream Commons in Allenwood, Union County, into a data center and add more buildings later, for a campus it has described as about 1 million square feet and up to 300 megawatts.

Gregg Township supervisors set to vote October 27 on PNK's data center plan at Great Stream Commons

The number that mattersPPL says serving the data center would take a new 6.8-mile, 230,000-volt transmission line on steel poles averaging about 140 feet tall, running from its Elimsport substation to the site.
Developer
PNK Group, a New York City industrial developer, through its subsidiary PNK P2 LLC, which owns the property. Chief Development Officer Anton Voronkin has presented the plans, attorney J. Michael Wiley of the McCormick Law Firm in Williamsport filed the applications, and Kimley-Horn engineers have presented site details.
Tenant
No end user has been named. PNK leases a separate building in the park to ModCorr, a modular prison maker, which isn't part of the data center plan.
Current stage
The Board of Supervisors closed a three-part public hearing on PNK's curative amendment and conditional use applications on September 14, 2026 and has until October 29 to decide; its October 27 special meeting notice lists a vote on the conditional use application. The township conditionally approved PNK's 69-kilovolt substation in August, but on October 6 the Union County commissioners denied it under the industrial park's covenants, and on October 21 they sent PNK a cease-and-desist letter saying substation site work had started without county approval and giving the company 30 days to confirm in writing that it had stopped. PPL's preferred route for the 6.8-mile, 230 kV line that would serve the site starts at its Elimsport substation, and PNK is to pay the costs. The township has also paused new data center applications for 180 days while it writes its own rules.
Decision body
Gregg Township Board of Supervisors (Chairman David Masser, Vice Chairman Michael Keiser and Supervisor Arthur Masser) decides the curative amendment and conditional use; the township planning commission is advisory. The Union County commissioners approve plans under the Great Stream Commons covenants, and the Pennsylvania Public Utility Commission will review PPL's new transmission line.
Top issues
Noise, especially low-frequency hum from chillers and backup generators; buildings about 500 feet from homes; the electricity demand and the new PPL transmission line it would require; water use and wastewater; vibration near an eye surgery practice next to the park; property values; and the lack of a named end user.
Key opponents
Gregg Township residents have filled every hearing, many wearing red, and have held weekly strategy meetings at Washington Presbyterian Church in Allenwood during the hearings. Residents also organize through a Facebook group called Gregg Township Community. The township planning commission recommended rejecting PNK's curative amendment in May 2026.
Key supporters
PNK Group and its consultants. Of seven nearby households whose letters were read at the July 20 hearing, five reportedly no longer oppose the project and two signed letters of support, and a resident urged supervisors in August to negotiate a community benefits agreement. No public official has been reported endorsing the project.

How we got here

PNK P2 LLC bought the 42.6-acre property at 198 Enterprise Blvd. in January 2022 and built a 478,379 square foot warehouse that has stood empty. At the supervisors' December 1, 2025 meeting the township said a data center isn't a use its zoning provides for, leaving it to the supervisors as a conditional use. PNK filed a curative amendment on February 19, 2026 and on March 2 presented a two-phase plan: convert the warehouse first, then build more data center buildings, a substation and a PPL switchyard. On May 4, before 114 residents, supervisors hired attorney Richard Shoch for the process, and the hearing first set for June was postponed at PNK's request. PNK filed its conditional use application May 22, and the township planning commission recommended rejecting the curative amendment. On July 6 supervisors voted to tell the Public Utility Commission that, if PPL's line is needed, the township supports running it through the federal prison property and state game lands so it doesn't take land from farmers and other residents. The hearing opened July 20 before more than 150 people, many wearing red, and ran nearly four hours; PNK said it had moved the substation and chillers away from homes and would use closed-loop cooling. On August 3 supervisors conditionally approved PNK's 69-kilovolt substation plan and hired attorney Brett Flower and acoustical consultant J. Michael Spencer. On August 20 they paused new data center applications for 180 days, a pause that doesn't cover PNK. Hearing sessions followed on August 25 and September 14, when the record closed. On October 6 the Union County commissioners denied the substation, and on October 14 the county said it was investigating whether site work had started without approval.

Update, October 26, 2026. On October 21, 2026 the Union County commissioners sent PNK Group a cease-and-desist letter saying work on its substation site at Great Stream Commons, including moving a stormwater basin, excavating and building a modified access road, had started without the county approval the park's covenants require. The letter demanded an immediate stop to the work and written confirmation within 30 days that non-protective construction had ceased.

What is at stake

Impacts raised and open questions

Noise and vibration

High

PNK's first proposed ordinance, filed in February 2026, would have limited normal operating sound to 65 dB(A) measured at residential property lines; residents and the planning commission pressed for tighter limits and attention to low-frequency noise, and the township hired an acoustical consultant to review PNK's numbers.

Noise and vibration

Medium

Testimony at the July 20 hearing put the closest data center about 500 feet from homes and the nearest generator about 850 feet from the nearest house; PNK said it had relocated the substation and equipment and switched to costlier noise-suppression technology.

The Standard-Journal

Visual and light

Medium

PPL's preferred route for the line needed to serve the data center is about 6.8 miles of double-circuit 230 kV line in Lycoming and Union counties on steel monopoles of roughly 90 to 180 feet, averaging about 140 feet, with trees cleared in any new right of way. Construction would run from late 2027 to the end of 2029.

Property values

Medium

A resident told supervisors that several of PPL's proposed route options crossed farms enrolled in agricultural preservation, and the township asked the PUC to route any line through the federal prison property and state game lands so it doesn't take land from farmers and other residents.

Gregg Township

Water

Medium

PNK's application says the building is served by Pennsylvania American Water and the Gregg Township Municipal Authority sewer, and that it will use air-cooled chillers, dry coolers or closed-loop recirculating systems to limit water use, coordinating capacity with Pennsylvania American Water during land development.

Gregg Township

Public safety

Low

An eye surgery practice next to the park told supervisors that construction vibration had already affected its surgical microscopes and that it worries about vibration from a data center.

Coverage of this project

Sources

Know your rights

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.

Take action

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.
