The EPA Proposes Optional Data Center Pollution Disclosure
The US Environmental Protection Agency (EPA) has proposed making public disclosure of air pollution from minor sources, including data centers, voluntary rather than mandatory. This change aligns with recent exemptions the administration has granted to data centers and rockets from certain environmental laws.
Background:
Under the Clean Air Act, facilities classified as minor polluters are currently required to disclose their emissions to the public through state agencies. The proposal would shift this decision to state and local officials, effectively making disclosure optional.
Data Centers as Minor Sources:
Data centers in Northern Virginia, for example, operate approximately 10,500 diesel generators with a combined capacity of 27 gigawatts. This clusters of generators, each individually permitted, avoids triggering stricter federal review, despite their collective impact.
Impact on Communities:
Nitrogen oxides, a primary component of data center emissions, contribute to ground-level ozone and are linked to asthma, heart disease, and cancer. Without mandatory disclosure, residents cannot easily access information about their air quality, hindering legal challenges and local campaigns against pollution.
Criticism:
"Every single person in this country deserves clean air, and the EPA’s plan opens the door to silence communities concerned about pollution," stated Jeremy Fisher, a senior adviser at the Sierra Club.
Regulatory Actions:
The EPA's proposed changes include:
- Guidance for data center developers
- Clarification on backup generators
- A proposed redefinition of when construction is deemed to begin
A public hearing was held on July 22, and the comment period closed on August 21. The EPA's final decision will follow.
Contrast with Europe:
The contrast with Europe's stricter regulations on data center emissions highlights the proposed changes' potential impact on environmental transparency and community health.
