– Decisions today will be used to prepare design document in March
• 2b: Geographic SA
– Contributions of Western State’s anthropogenic emissions to ozone,
PM, visibility and deposition
• 2c: Emissions Sector SA
– Oil and Gas, EGUs, mobile etc.
• 2d: Detailed SA in Three-State 4 km domain
– Sub-state Basins, Source Categories, etc.
• 2e: SA Website Visualization Tool
• 2d: CMAQ detailed SA in Three-State 4 km domain

Subtask 2b: Geographic SA
• Contributions of anthropogenic emissions
from western states to ozone, PM, visibility
and deposition using 2011a2 CAMx platform
– Obtain contributions for which western states?
– Which source categories to model separate SA?
– How to post-process for useful displays?
– Relationship with WestJumpAQMS 2008 SA?
– Relationship with EPA Jan 2015 Transport
2018_2011 SA?

WestJumpAQMS Geographic SA
• CAM V5.4.1 – CB05
• 2008 Base Case EI
• Ozone (APCA) SA
– 36/12 km CONUS/WESTUS
• PM (PSAT) SA
– 36 km domain
– SO4, NO3/NH4, Primary PM
– No SOA – Can post-process
CAMx SOA results to get
mainly Anthro. (SOAA) and
Biogenic (SOAB) SOA
• Fires contribute to both
• 21 Source Regions:
– 17 Western States, EUSA, Mex,
Can, Off-shore
• 5 Source Categories:
– Natural, Anthro., 3-fires (WF,
Rx, Ag)
• 107 Source Groups (21x5+2)
Post-Processing WJ Geographic SA
• CSAPR-type analysis:
– Use MATS to estimate
contributions of upwind state
anthropogenic emissions on
2008 ozone and PM2.5
Design Values
• Spatial maps of state
contributions
• State contributions to
visibility
– Controllable = Anthro+Rx+Ag
• State contributions to
DMA8 ozone and PM2.5

EPA Jan 22, 2015 Ozone Transport
Analysis
• CAMx v6.1 – 2011v1 Platform -- 12 km CONUS domain
• APCA Ozone SA – 2018 Future Year Emissions Scenario
• Contribution Categories:
– Anthro. NOx and VOC from
each State
– Anthro from All Tribes
– Biogenic (CONUS)
– Boundary Conditions
– Other (WF, RX, Ag, OffShore, Can and Mex)

EPA Jan 22, 2015 Ozone Transport
Analysis
• Project current (2009-2013) ozone AvgDV and MaxDV to 2018
using new MATS (Dec 2014)
– Nonattainment and Maintenance Monitors
• Determine contribution of Upwind State’s Anthro. Emissions
to downwind monitors
– Unlike CSAPR and WJ, MATS approach not used
– If Upwind State contributes ≥ 1% NAAQS 2018 DV  Significant
Contribution
• Outside of CA, Chatfield, Colorado only
nonattainment/maintenance monitor in west
– Significant contributing States to Chatfield: CA (1.17 ppb); UT (0.92
ppb); and WY (1.29 ppb)

• Configure CMAQ exactly the same as CAMx
Subtask 2d Detailed 4 km SA modeling

of the features and options
• Compare CAMx and CMAQ SA results
• Develop recommendations for SA modeling
using CAMx and CMAQ

– CSU working to integrate in DW
• For 3SAQS Web Tool will implement all days
– Include MPE and CONUS BC contribution
– More drill down capability
