Cumulative Impacts

Presented at the February 1, 2018 Air Quality Coalition meeting 2

  • Recognize community concerns
  • Various interpretations
  • Cumulative air quality impacts that are evaluated

in the permitting process for common pollutants

Two Approaches

Presented at the February 1, 2018 Air Quality Coalition meeting 3

  • Common Pollutants -- Allowed levels of air

pollution in the form of ambient standards (concentration)

  • carbon monoxide (CO)
  • nitrogen oxides (NOX)
  • sulfur dioxide (SO2)
  • particulate matter (TSP, PM10, & PM2.5)
  • Lead (Pb)
  • hydrogen sulfide (H2S)
  • Performance standards & practices
  • Hazardous air pollutants

Cumulative Impacts - Air Dispersion Modeling

Presented at the February 1, 2018 Air Quality Coalition meeting 7

  • Environmental Protection Agency approved

software and guidelines

  • Existing pollution, air emissions from the

proposed stationary source and weather conditions are used in the model

  • Increasing complexity

Over Predicts Impacts - Perfect Storm

Presented at the February 1, 2018 Air Quality Coalition meeting 8

  • Highest Impacts
  • Weather condions → polluon accumulates
  • Proposed project operating with permitted

pollution rates during all of the requested

  • perating hours
  • Near-by sources operating with permitted

pollution rates during all of the requested

  • perating hours

Wrap Up

Presented at the February 1, 2018 Air Quality Coalition meeting 28

  • Cumulative Impacts – Common Pollutants
  • Existing air pollution measured at monitors
  • Proposed air pollution
  • Near-by large near-by air pollution
  • Perfect storm maximizes air quality protection
  • Approaches for common pollutants & hazardous

air pollutants have been effective

  • Further discussion of hazardous air pollutants is

needed
