} Learn what CAC plants release to air, water and land } Help public learn about chemicals in the community } Tool for helping CAC hold plants accountable } Plants may learn from their own reports and others } Allows us to track trends; but trends are affected by changing circumstances 3 DPCAC 2018 Emissions Presentation

• Combination of estimates and measurements o Accuracy growing over the years • Measurements from Continuous Emissions Monitoring Systems (CEMS), stack and vent tests, lab analysis, other direct measurements • Estimates from calculations based on fuel consumption, mass balance, engineering calculations, throughput formulas, flow measurements, inventory loss, production data, field surveys o Fugitives often estimated by EPA’s AP-42 factors o Direct measurements may be incorporated into calculations • Changing methods to improve accuracy may result in different numbers. 4 DPCAC 2018 Emissions Presentation

• Changing number of plants in CAC • Actual long term changes in emissions o Adding units or closing them o Investing in pollution prevention • Making a different mix of products; e.g. more or less volatile • Production/customer demand -- up or down • Maintenance and related shutdowns and startups • Upsets, leaks, spills • Changing calculation methods 5 DPCAC 2018 Emissions Presentation

Air Emissions Inventory Toxics Release Inventory q Federal requirement (EPA) q State requirement (TCEQ) q Criteria pollutants q Selected toxic chemicals q Public right-to-know q Air contaminants only q Almost all contaminants q Contaminants released to air, (even small quantities) water, land, & offsite transfers q Chemicals from list of >650 that q Basis for setting fees meet threshold quantities Both Reports q Include point source and fugitive emissions q Include permitted, upset and maintenance emissions q Are based on direct measurements, engineering estimates, and factors q Exempt small facilities 7 DPCAC 2018 Emissions Presentation

Thresholds are specified amounts of chemicals used during the calendar year that trigger reporting requirements. • Manufactures or Imports – 25,000 pounds • Processes – 25,000 pounds • Otherwise Uses – 10,000 pounds • 21 chemicals and chemical categories are classified as persistent, bioaccumulative, toxics and have lower reporting thresholds 100 pounds o 10 pounds o 0.1 grams o 8 DPCAC 2018 Emissions Presentation
