Briefing on FY14-15 Work Plan Technical Activities Sue Kemball-Cook and Greg Yarwood NETAC Technical Committee Meeting April 22, 2014
Today’s Presentation • Update on FY14-15 work plan tasks • 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
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
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
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
Ozone Modeling • Improve model performance so that NETAC has two SIP-quality 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
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
