Chapter 5 of 10
Fight in Washington
Federal law gives you tools the developer hopes you don't know about.
Summary
Federal law provides tools that most communities do not know they have. This chapter explains how to use them, even when the data center itself is a private project.
The chapter opens with the story of Maryland farmers fighting a high-voltage transmission line being built specifically to serve data centers. The line required federal permits, which opened the door to federal environmental review.
The National Environmental Policy Act, or NEPA, requires federal agencies to study the environmental effects of major actions before approving them. If a data center project involves any federal permit, federal funding, or federal land, NEPA may apply. The chapter explains how to participate in scoping meetings, submit effective comments, and argue for analysis of cumulative impacts — the combined effect of multiple data centers in a region, not just one project in isolation.
The Clean Water Act gives you two tools. Section 404 requires a permit from the Army Corps of Engineers before anyone can fill or disturb wetlands. Check whether the project site contains wetlands, submit comments during the public notice period, and challenge inadequate reviews. Section 402 covers water pollution discharge permits, which may apply to data center cooling water.
The Endangered Species Act can block or modify projects that threaten listed species or their habitats. If the project site or surrounding area contains habitat for protected species, this law may apply.
The Federal Energy Regulatory Commission, or FERC, oversees interstate transmission lines and wholesale electricity markets. FERC runs capacity auctions that directly affect your electric bill. The chapter explains how to file comments in FERC proceedings.
The Department of Energy is involved in grid planning, transmission approvals, and energy efficiency standards. The Clean Air Act may apply if the data center has large diesel backup generators that emit significant air pollution. Citizen suit provisions in both the Clean Water Act and Clean Air Act let private citizens enforce these laws when agencies fail to act.
Finally, contact your members of Congress. They have constituent service offices, oversight power, and the ability to put pressure on federal agencies. A letter from a senator to the Army Corps of Engineers can change the pace of a permit review overnight.
Key Question
"Does this project involve any federal permit, funding, or land that triggers federal environmental review?"
Action Plan
Your checklist for this chapter
- 1
Check for federal triggers
Determine whether the project involves federal permits (wetlands, air quality), federal funding, federal land, or federally regulated transmission lines. Any of these can trigger NEPA review.
- 2
Participate in NEPA review
Attend scoping meetings, submit detailed comments, and demand analysis of cumulative impacts from all data centers in your region, not just the one project being reviewed.
- 3
Check for wetlands and endangered species
Review the National Wetlands Inventory and consult the U.S. Fish and Wildlife Service database for the project area. If wetlands or listed species are present, federal permits are required.
- 4
File comments with FERC
Monitor FERC proceedings related to capacity auctions and transmission projects in your region. File public comments explaining how grid expansion for data centers affects local ratepayers.
- 5
Contact your members of Congress
Write to your U.S. representative and senators. Ask for oversight of the permitting process. Congressional inquiries can accelerate agency review and draw public attention to a project.
Checklists & Step-by-Step Guides
How to Use NEPA
- Scoping. Submit written comments listing what you want studied: water use, air quality, combined impacts, harm to wildlife.
- Draft review. When the agency publishes a draft EA or EIS, a public comment period follows. Look for gaps.
- Final challenge. If the agency issues a FONSI and you believe the review was lacking, that ruling can be challenged in federal court.
How to Use Section 404 of the Clean Water Act
- Check for wetlands at the National Wetlands Inventory (U.S. Fish and Wildlife Service).
- Watch for the permit application on the Army Corps public notices database.
- Submit comments explaining how the project will affect local waterways and wildlife.
- Challenge the permit in federal court if the process was flawed.
What You Can Do About Clean Air Act Violations
- Contact your state air quality agency.
- Ask whether the data center has an air permit and how many generators are on site.
- Ask whether combined emissions trigger New Source Review.
- Check the EPA ECHO database for existing violations.
- If the agency is slow to respond, contact the EPA regional office.
How to File a FERC Comment
- Search for the docket number on the FERC website.
- Write a short letter with your name, address, and docket number.
- Explain how the issue affects you — cite your electric bill increase.
- File one. Ask ten neighbors to file too.
Reference Tables
Key Federal Environmental Laws for Data Center Fights
| Law | What It Covers | Key Trigger |
|---|---|---|
| NEPA | Environmental impact of major federal actions | Federal permit, funding, or land |
| Clean Water Act §404 | Filling or disturbing wetlands | Any development that fills wetlands |
| Clean Water Act §402 (NPDES) | Water discharges: cooling water, stormwater | Discharge to streams |
| Clean Air Act | Air pollution from backup diesel generators | Air permits, New Source Review |
| Clean Air Act Citizen Suit | Government failure to enforce violations | 60 days' written notice required |
| Endangered Species Act | Threatened or endangered species | Species presence triggers consultation |
NEPA Review Types
| Type | Description |
|---|---|
| Environmental Assessment (EA) | Initial review to determine significance |
| Environmental Impact Statement (EIS) | Full detailed review of alternatives — can take two or more years |
| Finding of No Significant Impact (FONSI) | Agency determination no EIS needed — can be challenged in court |
| Categorical Exclusion | Project skips review entirely. Executive order aims to create these for AI data centers over 100 MW. |
Warning Signs
- Federal tools cut both ways. The federal government can help communities fight data centers — or help data centers fight communities.
- An executive order tells agencies to create categorical exclusions for AI data centers over 100 MW — meaning projects skip review entirely.
- Do not assume a NEPA review will happen on its own. Ask the federal agency in writing.
- Not all wetlands appear on the National Wetlands Inventory maps.
- The Data Center Coalition nearly tripled its lobbying spending in Q3 2025. The electronics sector spent $226 million on lobbying that year.
- The trend: fewer reviews, faster timelines, and less public input at the federal level.
Questions to Ask
- 1. Does the project require a federal permit (like a 404 wetlands permit)?
- 2. Does the project receive federal funding?
- 3. Did the agency study cumulative impacts from all data centers in the area?
- 4. Does the data center discharge cooling water or stormwater? Does it have an NPDES permit?
- 5. Is a transmission line planned near your community?
- 6. Where does your member of Congress stand on data center energy costs?
Key Facts
NEPA requires environmental review when federal permits, funding, or land are involved — even for private projects.
The Clean Water Act Section 404 requires permits before wetlands can be filled or disturbed.
FERC capacity auctions directly affect household electric bills by setting wholesale power prices.
Citizen suit provisions in the Clean Air Act and Clean Water Act let private citizens enforce environmental law when agencies fail to act.
Case Studies
Maryland Farmers vs. the Transmission Line
Maryland farmers organized against a high-voltage transmission line being built to serve data centers. Because the line required federal permits, NEPA environmental review was triggered, giving the community a formal process to challenge the project and demand comprehensive impact analysis.

"Cumulative impacts matter. The question is not just what one data center does to your community — it is what ten of them do."
