Overview

EPA defines fugitive emissions as unintended emissions from facilities or activities (e.g., construction) that "could not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening." In general, the decision whether to consider emissions as fugitive is a factual determination made by the state permitting agency on a case-by-case basis.

The following are examples of fugitive emissions and fugitive emissions sources:

  • Dust
  • Fine particles
  • Aerosols
  • Quarries
  • Storage piles
  • Leaks or releases from valves, pumps, compressors, flanges

Methods of controlling fugitive particulate emissions include:

  • Enclosures
  • Water spray
  • Chemical dust suppressants
  • Windscreens
  • Vegetative barriers
  • Sweeping paved roads
  • Reducing speed on unpaved roads
  • Paving roads
  • Covering open trucks

The primary method of controlling fugitive VOCs from leaks is the implementation of a leak detection and repair program.

Fugitive Emissions and Major Source Definitions

Generally, a major source is any source that has the potential to emit:

  • 100 tons per year (tpy) or more of any regulated pollutant
  • 10 tpy of a hazardous air pollutant (HAP)
  • 25 tpy of any combination of HAPs

Sources in nonattainment areas for ozone, carbon monoxide (CO), or particulate matter (PM-10) have lower thresholds, depending on the area's classification. See the ...
