Pennsylvania has become a for data center proposals and about where to build them.
I’m a law professor and of Penn State’s Center for Energy Law and Policy. I’m also a native of Archbald, a borough of 7,500 residents in the Lackawanna Valley in northeastern Pennsylvania. My hometown has because of proposals for multiple data centers that would cover .
Because of my professional and personal interest in data centers, I have been researching local responses to data center proposals across Pennsylvania. I’ve learned there are a that local officials and citizens are taking into account when they evaluate data center proposals.
Pros and cons of big data centers
At its most basic, a data center is a building that houses and .
Because data centers tend to be large developments, hosting one can provide a community more tax revenue. This revenue comes from as well as .
However, these job are mostly limited to the construction phase. suggests a moderately large data center would create about 15-30 long-term jobs.
On the other hand, data centers raise concerns about environmental and social impacts. They consume and , leading to fears of for other consumers.
Emissions from diesel generators can contribute to local air pollution and worsen .
Data centers have also been shown to create , raising the local air temperature by an average of 3.6 degrees Fahrenheit (2 degrees Celsius).
due to the noise from cooling systems and diesel generators. And some residents object to what in rural or suburban communities.
Communities can plan ahead
Because of the significant impact that a data center can have on its surroundings, communities benefit from planning ahead before any proposal has even been made in their area.
One of the most powerful tools a Pennsylvania municipality has is its under Pennsylvania’s .
Under this law, a municipality generally from its zoning ordinance a legal use of a property unless it is inherently objectionable. An example of an inherently objectionable use might be a in a heavily residential municipality.
But it within the municipality buildings or other structures can be constructed and how they can operate.
Many Pennsylvania municipalities, including and , have amended their zoning ordinances to account for data centers.
Zoning ordinances are a powerful tool
The Pennsylvania municipalities of and have restricted data centers to industrial zones. Mayfield Borough has restricted them to zones.
Municipalities can also determine what level of municipal approval is required for a data center development. In Pennsylvania, allowed “by right,” “special exception” or “conditional use.”
“By right” means that no approval is required as long as ordinance provisions are followed.
By “special exception” requires approval from a municipal zoning hearing board.
By “conditional use” requires approval from the municipality’s governing body. This might be a board of supervisors or borough council.
Most Pennsylvania municipalities that have addressed this issue have designated data centers as a . Some, such as Butler Township/Arendtsville Borough, have allowed them as a . When a for a conditional use or special exception, it must determine whether the proposed data center complies with the zoning ordinance and that it would not otherwise injure the public interest.
Setback distances and impact studies
Another significant tool that municipalities have used is . A setback distance defines how far a data center structure must be from an adjacent property.
In Pennsylvania, ordinances have established setbacks for data centers from (15 meters) to (122 meters). Many ordinances establish longer setbacks from residential properties, hospitals or schools than from industrial sites.
Many ordinances also require plans or studies to be submitted as part of a zoning application. are common ones. These studies are intended to establish background noise levels for the area of the proposed data center and to identify ways to mitigate noise impacts.
Municipalities may also require developers to submit an , or , such as for a fire on-site.
How to protect your community
Learning about the specifics of a particular data center proposal can help a community to understand the potential impacts – both positive and negative – and prepare a response.
Local residents and officials should be poised to ask probing questions about:
- power and water demand, and the source of those resources
- infrastructure needs
- utility rate impacts
- cooling system design and noise and resource consumption impacts
- site design and landscape impact
- job creation and tax revenue projections
- noise mitigation strategies
- traffic effects
- air and water pollution emissions
Penn State Extension published a that may facilitate discussions with community officials and data center developers.
It may be possible in some circumstances for municipalities to with data center developers. These agreements can ensure that the host community obtains certain specified benefits, such as local development, as a result of the data center project.
The drive to build data centers and related infrastructure is moving quickly. By updating ordinances in advance, and diligently collecting information about any data center proposals that are made, local officials and citizens can protect the best interests of their communities.
