What Is TANKS?TANKS is a Windows-based computer software program that estimates volatile organic compound (VOC) and hazardous air pollutant (HAP) emissions from fixed- and floating-roof storage tanks. TANKS is based on the emission estimation procedures from Chapter 7 of EPA's Compilation Of Air Pollutant Emission Factors (AP-42). The user's manual, available in Adobe Acrobat format and WordPerfect, explains the many features and options of TANKS. The program includes on-line help for every screen.
AudienceTANKS is designed for use by local, state, and federal agencies, environmental consultants, and others who need to calculate air pollutant emissions from organic liquid storage tanks.
Program CapabilitiesTANKS uses chemical, meteorological, roof fitting, and rim seal data to generate emissions estimates for several types of storage tanks,including:
See the TANKS FAQ for additional information about TANKS.
The TANKS program employs a chemical database of over 100 organic
liquids, and a meteorological database of over 240 cities in the United
States. The program allows the addition of more chemicals and cities,
if desired. TANKS is capable of calculating individual component
emissions from known mixtures and estimating emissions from crude oils
and selected refined petroleum products using liquid concentration HAP
profiles supplied with the program.
TANKS 4.09 will run on Windows XP desktops. The program requires 8 MB of random access memory (RAM). The installed program requires 8 MB of available hard disk space. TANKS is designed for operation from a PC's hard drive. Many users are able to share tank databases via LAN connections to increase the utility of the program.
You must have administrative rights to all folders on your desktop. The installation process installs
files to the Windows system directory.
TANKS is not supported on desktops using Windows Vista or Windows 7. Suggestions and fixes for running TANKS on a Vista or Windows 7 platform will be posted whenever possible. Please see the "Errors and fixes" table below.

TANKS 4.09D errors and available fixes
|Determining monthly emissions.
One of the errors in TANKS is that it uses annual average liquid bulk temperature when computing monthly emissions rather than calculating a monthly liquid bulk temperature. Since TANKS uses annual average liquid bulk temperature in the monthly calculations, a change in the temperature for one month will affect every month, in that changing one month changes the annual average. As such, the TANKS program will NOT adequately account for the monthly variations. Therefore, TANKS should NOT be used for determining maximum monthly true vapor pressure and users should not rely on the TANKS model for accurately determining monthly emissions in general. Users should rely on the equations specified in AP-42 Chapter 7.1 to perform those calculations.
|Use section 7.1 of AP42, Organic Liquid Storage Tanks to correctly calculate monthly emissions.|
