What equipment is authorized?
The permit and application may identify engines, turbines, fuel, ratings, counts and controls.

Data center
air pollution
Use permits to identify authorized equipment and limits—then keep those values separate from operation, monitoring, exposure and health evidence.
What limit is per unit or combined?
Do not add permit values unless the document explicitly identifies a combined total.
Look for: Emission-limit table with cited pagesWhat actually operated?
Permitted hours and potential emissions are not operating logs or measured emissions.
Look for: Compliance certification, operating log or emissions reportWhat evidence addresses exposure?
A permit limit alone cannot establish ambient concentration, exposure or health outcome.
Look for: Monitoring data, dispersion analysis and health methodologyVERIFIED STARTING POINTS

COMMON QUESTIONS
Do backup generators run continuously?
Normally they serve emergency power and testing roles, but the governing permit and operating records control. Do not infer operating frequency from the number of permitted units.
Are permit limits measured emissions?
No. A permit may use maximum or conservative assumptions. Actual emissions depend on operating hours, load, fuel, controls and compliance data.
Does an air permit prove a health impact?
No. Exposure and health questions require additional evidence such as monitoring, modeling, population data and an appropriate health methodology.
