Advanced Tank Emission Calculation

Companies are required to perform proper tank emission calculations based on the methodology provided in U.S. EPA’s Compilation of Air Pollutant Emission Factors (AP-42). This complicated process was previously facilitated by EPA’s tanks emissions estimation software, TANKS 4.09d. However, in 2014, EPA announced it would no longer maintain the TANKS 4.09d software. While TANKS 4.09d is still available on EPA's website, EPA States that the model should be "used at your own risk". Instead, EPA recommends using the equations/algorithms specified in AP-42 Chapter 7 for estimating VOC emissions from storage tanks. This one-day course covers VOC emission calculation methods based on the algorithms specified in AP-42 Chapter 7 and API Technical Report 2568, November 2007 and some local agency guidance.

The course provides a detailed look into air emission issues related to aboveground storage tanks and provides insight on best practices for emission calculations, regulatory compliance, and recordkeeping. Due to the complexity of the AP-42 Chapter 7 methodology and equations, the course will include demonstrations of popular tank emission calculation programs which follow the AP-42 methodology and will cover emissions estimates from fixed roof storage tanks and floating roof tanks. Attendees will be prepared with the TankESP program database version for practice. Some other hot spots (e.g., short term emission estimates, throughput determination, heated tanks) are also discussed. Finally, the course provides recommendations on how to improve tank data quality and the accuracy of emissions estimates.
