COUNTY OVERVIEW

What the current record shows

Fairfax County is part of the broader Northern Virginia data-center region. State air permits can apply when proposed stationary equipment would emit regulated pollutants above Virginia’s exemption thresholds.

The current index is intentionally limited to documents that can be traced to a primary government source. It should not be read as a complete inventory of every data center or every environmental approval in Fairfax County.

COMMON QUESTIONS

Is this a complete list of data centers in Fairfax County?

No. It is a focused index of source documents reviewed by Public Evidence Project. A facility may exist without appearing in this collection.

Does an air permit mean a facility violated pollution rules?

No. A permit defines authorized equipment, limits and operating conditions. Inclusion is not evidence of a violation.
