Start by asking what decision is actually before the hearing body, what evidence it may consider, and what conditions it can impose. Then ask for quantified estimates of the project’s electricity and water use, who pays for new infrastructure, and how promises on noise, emissions, jobs, and community benefits will be monitored and enforced. The right authority and the answers it can give depend on the project’s location and the type of approval being reviewed.
First, find out what the hearing can decide
A data center may require several separate approvals. A zoning hearing, an air permit meeting, a water-discharge review, and a utility proceeding can involve different agencies, records, and legal powers. A hearing about land use may not decide who pays for transmission upgrades; a utility regulator may not decide whether a building fits local zoning.
Before commenting, identify the application on the agenda and ask which decisions remain with other bodies. A useful opening question is: “What can this body approve, deny, or condition today, and what issues are outside its authority?”
- Which application, permit, or plan is under review?
- Is approval discretionary, or is the body checking whether the application meets preset standards?
- What evidence may the body consider, and which conditions can it legally impose?
- What are the deadlines and rules for written comments and oral testimony? Where will comments and agency responses be posted?
- What review or appeal process applies after a decision?
Procedures vary by jurisdiction. Fairfax County, Virginia, says some special exceptions and substation approvals require public hearings, while data centers that meet standards in certain heavy-industrial zones may proceed without one. That is a local example, not a rule for other counties or states.

Ask for the project’s electricity demand and grid costs
“How much power will it use?” is a good start, but ask for both peak demand and expected annual consumption. Peak demand, usually expressed in megawatts, helps show the maximum load the facility may place on the grid; annual energy use describes consumption over time. Ask what assumptions underlie each estimate and whether the numbers cover the full project or only its first phase.
- What is the projected peak electrical demand, and what is the expected annual consumption?
- What generation, transmission, distribution, substation, or other utility upgrades are needed, and when must they be built?
- Who pays for each upgrade? Can the applicant or utility point to a tariff, interconnection agreement, or other enforceable document showing the allocation?
- What operating changes would the facility make during grid emergencies or shortages?
- After the facility opens, how often will actual use be reported, and where can the public see it?
Do not treat a forecast of increased local demand as proof that household bills will rise by a particular amount. Ask which regulator sets the relevant rates, what costs may be assigned to customers, and what evidence supports the allocation. In Virginia, Fairfax County says key energy matters are controlled by the State Corporation Commission rather than the county; another jurisdiction may divide authority differently.
Pennsylvania offers a state-specific example of stronger cost and disclosure requirements. Its Executive Order 2026-05, announced August 18, 2026, directs state agencies to tie data-center permit review to legally enforceable GRID commitments and local approvals. The state describes commitments addressing full power and infrastructure costs, public engagement, workforce and community benefits, and environmental protection. The order is not national law. In the same announcement, Pennsylvania reported that publicly sourced databases contained more than 100 proposed projects: 58 had engaged with the Department of Environmental Protection (DEP), 15 had applied for at least one DEP permit, and five had all permits needed for their first phase. Those are Pennsylvania’s reported counts as of its August 18, 2026 announcement, not a national project inventory.
Get annual and peak-day water estimates
Water demand can vary with the cooling design, weather, operating conditions, and water source. Ask for the project’s estimated annual use and maximum single-day demand, rather than relying on a general claim that data centers use either “a lot” or “very little” water.
- What are projected annual consumption and peak-day demand, and where will the water come from?
- What cooling system is proposed? Could recycled water, air cooling, or a closed-loop design reduce demand for potable water?
- How will wastewater, stormwater, and any water discharge be handled, and which authority reviews discharge quality?
- What happens during drought, a supply emergency, or a failure of the water system?
- Will actual use and peak-day demand be reported publicly after opening, and how often?
Pennsylvania’s GRID implementation calls for reporting annual water consumption and maximum single-day demand, and says water-recycling or closed-loop cooling technologies should be used where feasible under that framework. St. Louis’s April 2026 announcement listed closed-loop and air-cooled equipment requirements for one project. Neither example establishes a requirement for a project elsewhere.
Ask how generators, air emissions, and noise will be controlled
Backup generators may be tested as well as used during outages. Ask about the full operating scenario—not just the equipment’s rated capacity—and look for permit terms that specify when testing can occur, how it is logged, and what restrictions apply.
- How many generators are planned, what fuel will they use, and what air permits apply?
- When may the generators be tested, how long may each test run, and are there limits for poor-air-quality days?
- What equipment will produce continuous sound, including cooling equipment and generators? What sound levels does the study predict at nearby homes during the day and night?
- Does the noise study consider tonal or low-frequency sound and the cumulative effect of multiple equipment sources?
- Who will monitor sound and emissions, how will complaints be handled, and what correction deadlines or consequences apply if limits are exceeded?
Pennsylvania’s GRID implementation describes limits and operational logging for backup generation. St. Louis’s published conditions for one project limit generator testing to specified weekday time windows and require noise-emitting equipment to be placed away from primary frontages and enclosed in acoustically treated structures. These are examples of project- or jurisdiction-specific terms, not universal standards.
A portable sound level meter can help a resident keep a rough personal record, but it is not a substitute for a qualified, code-compliant acoustic study. The reviewed sources do not establish that consumer meters meet regulatory measurement standards.

Check land use, environmental impacts, and nearby receptors
Ask for a clear list of approvals still required and the agency responsible for each one. Then check whether the application addresses effects on people and places around the site—not only the property boundary.
Rank #4
- Which land-use approvals and environmental permits remain, and which agency handles each?
- What studies cover air and water quality, stormwater, wetlands, habitat, traffic, heat, construction impacts, and cumulative effects?
- How close are homes, schools, parks, and other sensitive uses? What setbacks, screening, lighting controls, and landscaping are proposed?
- If monitoring shows a permit limit has been exceeded, what corrective action, operating restriction, or other remedy can the regulator require?
Fairfax County’s description of its local process illustrates why the agency list matters: local zoning and hearing procedures are distinct from Virginia agencies’ roles in key energy, air-pollution, and water-discharge matters. Verify the actual division of authority for the proposed project rather than assuming the county hearing covers every issue.
Separate construction jobs, permanent jobs, and public costs
Job claims can refer to very different things. Ask the applicant to separate temporary construction employment from the smaller set of ongoing operating positions, describe the skills required, and state which commitments—if any—will be binding.
- How many construction jobs and permanent operating jobs are expected, over what time period, and what skills will those roles require?
- Are local hiring, apprenticeship, or training commitments proposed? Who is responsible for delivering them, and how will results be reported?
- What tax exemptions or incentives apply, what public revenue is forecast, and what additional infrastructure or public-service costs are expected?
- If a community-benefit agreement or framework is proposed, who helped negotiate it, who receives benefits, when will they be delivered, and how is performance enforced?
Pennsylvania’s 2026 policy calls for local workforce and community-benefit commitments, but whether a particular hearing body can require or negotiate them depends on local law. St. Louis announced a community-benefit framework alongside project-specific conditions in April 2026; that example does not establish what another locality can require. For scale, Fairfax County reported that data centers contributed approximately $110.6 million to its General Fund in tax year 2026, about 1.9% of its FY 2027 General Fund revenue. This is a Fairfax County figure, not a typical contribution elsewhere.

A promise is more useful when it identifies a responsible party, a measurable standard, a reporting schedule, and a remedy for noncompliance. For every proposed mitigation or community commitment, ask:
- What exact requirement will appear in the permit, approval, or agreement?
- Who measures compliance, and who independently verifies the results?
- How often will monitoring data be reported, and where will the public be able to inspect it?
- What complaint process will operate during construction and after the facility opens?
- What happens if the project misses a commitment: a deadline to correct it, a penalty, a permit change, or an operating restriction?
Pennsylvania’s 2026 order describes public energy and water reporting, a public permit-status map, and a prohibition on nondisclosure agreements for data-center projects under that state framework. In St. Louis, the city published detailed conditions and a basis for ongoing monitoring for one project. When a commitment is not written into an enforceable instrument, ask who has authority to make it binding.
Compare proposals using the same measures
If more than one site or design is under consideration, ask applicants to use matching units, time periods, geographic boundaries, and assumptions. Otherwise, a peak-demand estimate for one proposal may be compared misleadingly with an annual-energy estimate for another.
| Measure | What to compare consistently |
|---|---|
| Electricity | Peak demand and annual consumption, with project phase and forecast assumptions identified. |
| Grid infrastructure | Needed generation, transmission, distribution, and substation work; schedule and cost responsibility for each. |
| Water | Annual use, peak-day use, source, cooling design, and wastewater or discharge plan. |
| Generators and noise | Backup strategy and emissions controls; modeled sound at sensitive locations, including time of day and cumulative sources. |
| Land and community effects | Land, air, water, traffic, construction, and other impacts, using the same study boundaries where possible. |
| Jobs and public finances | Temporary and permanent jobs separately; local hiring; net public revenue after incentives and expected public costs. |
| Accountability | Public access to records, monitoring schedule, responsible regulator, enforceable commitments, and remedies. |
Prepare a focused comment for the hearing record
Choose the questions that connect to the decision in front of the body. A short, specific comment is easier to answer and more useful in the public record than a long list that asks one agency to resolve issues outside its authority.

- Submit by the stated deadline and keep a copy of your written comment and any response.
Where the application does not provide a reliable project-specific figure, ask the applicant and competent regulator to provide one. The reviewed sources do not establish a nationally representative typical figure for data-center water use, noise, household bill impacts, or local job creation; a local proposal’s own documents and regulator records are the relevant evidence.
