States are required to submit Emissions Inventories of air pollution sources to USEPA. These include major stationary sources (industrial facilities normally called Point Sources), Area Sources (small facilities which include many individual locations, such as gas stations, dry cleaners, etc.), and Mobile Sources (cars, trucks, boats, etc.). Only major stationary sources are required to be reported to USEPA every year. Area and Mobile sources are reported every three years. The most recent three-year inventory was 2011.
We are currently preparing the 2014 Point Source inventory. Please be advised that the USEPA routinely replaces and retires NAICS, SCC, Pollutant, and Control Device codes. To ensure that valid codes are used, the DAQ may have revised your emissions inventory data accordingly. Therefore, codes found in the rolled-out 2014 data may be different than what you provided for 2013.
Once gathered, this data is used in verifying whether air programs previously enacted are having the desired effect and to plan what air programs are necessary in order to ensure air quality is improved or maintained. Additionally, USEPA uses your emissions estimates for modeling purposes for new rule development and, especially for toxic air pollutants, to make risk assessments to nearby communities.
We have replaced our old point source emission inventory software (i-STEPS) with the new State and Local Emission Inventory System (SLEIS). West Virginia is one of several state and local air pollution agencies using the SLEIS software. i-STEPS is no longer usable for submittal. The following announcements refer to the status of the 2014 Point Source inventory and the SLEIS software.
In order to use SLEIS, an account must be established for you. If you have not already done so, please download, complete, save, and email the registration form (available from the SLEIS webpage) to: firstname.lastname@example.org .

On the right side of the "Home" page, you will find helpful hints and notices about SLEIS.
- A training workshop for SLEIS was held at the Charleston DEP Headquarters on Tuesday, December 4, 2012. The contractor recorded the webinar as WMV files and has sent it to us with no post-processing. We have posted the unedited recordings here. Due to the file sizes (about 74MB and 97 MB) the files may need to be downloaded to your computer before being viewed.
Note that the first 3 minutes of the morning session contains opening remarks and is a bit hard to hear.
The PowerPoint used in the recording can be viewed separately here Workshop Power Point
