Conceptual Model Update
Emission Inventory Improvement
Control Strategy Evaluation Update
Ozone Modeling
SOF Study in the Sabine Industrial District
• For each task:
– Schedule
– Issues for consideration by the Committee
2
Conceptual Model Update
• Ambient data analysis
– To be performed following 2014 ozone season
– Different focus from previous studies for ambient data
analysis
 Examine relationship between weather conditions and
Northeast Texas ozone during recent years
• Modeling episode evaluation
– TCEQ has made August-September 2006 episode
available to Rider 8 areas
– Evaluate utility of this episode for Northeast Texas
3
Emission Inventory Improvement
• Oil and Gas Emission Inventory Update
– Update Haynesville Shale projections and emissions from
present through 2020 using drilling/production data
through 2013
 2012 base year for compatibility with TCEQ modeling
– Project conventional oil and gas activity and emissions
through 2020
– Start May, 2014
• Emission Inventory Review
– Review most recent 5-county area emission inventory
(2012) and underlying data
 Focus on assumptions used to develop oil and gas emissions
– Start May, 2014
4
Control Strategy Evaluation Update
• To be performed in early 2015
• Assess need for revisions to control strategies
developed under FY12-13 Work Plan
– Changes in regulatory environment
– Attainment status
5
Ozone Modeling
• Improve model performance so that NETAC has two SIPquality modeling episodes available
• Start May, 2014
• May-June 2005 model
– Episode includes types of days that are important at Longview
– Overestimate of power plant plume impacts
 Review of MM5 meteorological model performance
 Will consider running WRF for this episode
• June 2006 Model
– Performing better, but high bias still present
 Most pronounced on eastern border of Texas
 Affects model’s ability to accurately assess transported vs. local
contribution to ozone

SOF Study in the Sabine Industrial District
• Planning to run study in September 2014
• Looking to gain additional insights beyond
NETAC’s 2012 SOF study
• In discussions with Eastman about study
enhancements
7
Next Steps
• Quality Assurance Project Plan (QAPP)
development for all technical tasks in FY14-15
Work Plan
• Technical work will begin once TCEQ has
approved the QAPPs
