Fugitive Dust Project Phase One

1
Dust in the Wind
2
Fugitive Dust ProjectPhase One

• The WRAP Emissions Forum contracted with a team
  of contractors lead by ENVIRON to produce
  regional PM10 and PM2.5 emissions inventories for
  wind blown dust from vacant lands by employing an
  empirical methodology.
• These inventories are required by 309 of the
  Regional Haze Rule and will be used in air
  quality models as the basis for tracking progress
  in achieving the visibility goals under this rule.

Fugitive Dust ProjectPhase One

• The original project, Determining Fugitive Dust
  Emissions from Wind Erosion, had two goals
• to develop a general methodology, i.e., The
  MacDougall Method, and program code for
  estimating fugitive dust emissions from wind
  erosion and,
• to develop a PM2.5 and PM10 emissions inventories
  for the WRAP region modeling domain for 1996.
• The initial application of the methodology and
  the resulting products were to be treated as
  starting point with an expectation of making
  refinements.

Fugitive Dust ProjectPhase Two

• Previous efforts related to this project were
  under the purview of the Emissions Forum
  however, all future work will be the
  responsibility of the Dust Emissions Joint Forum.
• The objective of the follow on project
• Improve upon the initial work by applying the
  methodology with data that is more up to date and
  at a higher resolution.
• Assess model results based on adjustments to the
  modeling settings to determine if significant
  improvements can be achieved through global
  fine-tuning.

5
Fugitive Dust ProjectPhase Two

• This project will result in updated EIs for PM10
  and PM2.5 for the WESTERN REGION.
• Additionally, the model should be applied to high
  impact days (20 worst days), to determine the
  scope of applicationmonitoring emissions to
  determine what control strategies should be
  applied, when the control strategies should be
  applied, and the impact of such control
  strategies.

6
Fugitive Dust ProjectPhase Two

• The goal of the project is to improve upon the
  original project, Determining Fugitive Dust
  Emissions from Wind Erosion (AKA, The
  MacDougall Method), and to produce revised PM10
  and PM2.5 emission inventories for fugitive dust
  from wind erosion of vacant land based on wind
  tunnel studies.

Fugitive Dust ProjectPhase Two Study Area

• The geographic area for this project is the
  WESTERN REGION, which is identical to phase one.

8
Fugitive Dust ProjectPhase Two Refinement
Specifications

• Apply calendar year 2002 meteorological
  hour-by-hour data at 12km X 12km resolution.
• Apply more current land-use data at 12km X 12km
  resolution, based on 1km X 1km resolution data.
• Run Community Multi-scale Air Quality (CMAQ) with
  chemistry turned off.
• CMAQ will determine mixing height based MM5
  input.
• Emissions will be calculated in the first
  boundary layer.
• Inventories will be generated for the WESTERN
  REGION, which shall match the original project.

9
Fugitive Dust ProjectPhase Two

• Specific objectives include the following
• To demonstrate the Empirical Method for
  Determining Fugitive Dust Emissions from Wind
  Erosion of Vacant Land.
• Ensure that the PM10 and PM2.5 emission
  inventories are developed using hour-by-hour
  meteorological data at 12km X 12km resolution for
  the WESTERN REGION.
• Ensure that the PM10 and PM2.5 emission
  inventories are developed using a more current
  land-use dataset at 12km X 12km resolution for
  the WESTERN REGION.
• (Continued)

10
Fugitive Dust ProjectPhase Two

• Produce a PM10 emission inventory for the WESTERN
  REGION for calendar year 2002.
• Produce a PM2.5 emission inventory for the
  WESTERN REGION for calendar year 2002.
• Produce a PM10 emission inventory for the WESTERN
  REGION for the twenty percent (20) worst days,
  high impact days, during calendar year 2002.
• Produce a PM2.5 emission inventory for the
  WESTERN REGION for the twenty percent (20) worst
  days, high impact days, during calendar year 2002
• (Continued)

11
Fugitive Dust ProjectPhase Two

• Refine the general modeling methodology to
  calculate wind erosion, via datasets
  developed/compiled under terms of this contract.
• Refine program code for PM10 and PM2.5 for
  emissions modeling.
