Emissions Inventory Help Sheet for Reports Using EPA's TANKS 4.09d Program. This help sheet supplements “Instructions for Reporting 2017 Annual Air Pollution Emissions,” which you should refer to for additional information related to your report. This help sheet is for all facilities that use the EPA TANKS software. Feb 1, 2011 - TANKS v4.09D software can be downloaded for free at: under the How to Get TANKS 4.09D link. Because TANKS v4.09D is widely used, Appendix C of this Refinery Emissions Protocol document provides tips and insights on using the TANKS program.

EPA recently proposed its potential enforcement initiatives for the years 2017 through 2019, targeting what it views as the most important environmental problems where non-compliance is a significant contributing factor and where enhanced enforcement could make a difference. 1 First on the list of new, potential initiatives is protecting communities from exposure to toxic air emissions by focusing on emissions from organic liquid storage tanks. According to EPA, storage tanks are potentially significant sources of excess air emissions at many sites, including terminals, refineries, and chemical plants.

Some of these tanks are located in ozone nonattainment areas, communities of environmental justice concern, or other areas with sensitive populations. With increased scrutiny by EPA on tank emissions, facilities should review their current tank emission compliance demonstration methodologies, including emissions calculated for permitting and emissions inventories, to ensure they are accurate, up-to-date, and defensible in case of EPA review. In addition to proposing this potential enforcement initiative, EPA has stopped supporting its TANKS Database (TANKS 4.09d).

TANKS 4.09d has long been the standard emission calculation tool for tank emissions. While TANKS 4.09d is still available on EPA's website, EPA states that the model should be 'used at your own risk.'

Further, EPA recommends use of the equations and algorithms specified in AP-42 Chapter 7 2 for estimating VOC emissions from storage tanks. Fortunately, there is a better option available for calculating tank emissions. TankESP is a tank emissions calculation program (available in both database and spreadsheet versions) which follows the AP-42 Chapter 7 methodology for estimating VOC emissions from storage tanks.

This article details the known issues with TANKS 4.09d and describes why many companies are switching to TankESP. With an EPA enforcement initiative imminent and TANKS 4.09d no longer supported by EPA, it is critical for facilities operating large storage tanks to ensure their emission calculation methodologies are accurate and conform to EPA's recommended methodology. Deficiencies of TANKS 4.09d EPA's decision to stop supporting TANKS 4.09d is related to a number of documented technical issues with the program.

It was developed and maintained by EPA's Office of Air Quality Planning and Standards (OAQPS) as a tool to calculate emissions based on the methodologies in AP-42 Chapter 7. Both AP-42 Chapter 7 and TANKS 4.09d were last updated in November 2006. However, TANKS 4.09d has a number of documented errors in how the program incorporates the AP-42 Chapter 7 equations, including those described below. Annual bulk liquid temperature affecting all tanks (except heated tanks) In TANKS 4.09d, the liquid bulk temperature, for all tanks, is calculated using the annual average ambient temperature, which does not change from month to month even if the user selects the monthly report.

As a result, the liquid surface temperature is underestimated in summer and overestimated in winter. For tanks with greater throughput during the summer months, TANKS 4.09d will underestimate monthly emissions.

Heated vertical fixed roof tanks There are two issues with the emission calculation in TANKS 4.09d for heated tanks. First, TANKS 4.09d caps the stock true vapor pressure at the value corresponding to 100°F when the storage temperature exceeds 100°F, if using Option 1 (interpolation method) to determine vapor pressures. In Option 1, vapor pressures at a given temperature are determined by interpolation method using vapor pressures from 40°F to 100°F provided by the user. The storage temperatures of many heated tanks exceed 100°F; thus TANKS 4.09d typically underestimates emissions from these tanks.
