Version 3.1 of BSLC and User's Guide now availableA new, enhanced version of the Bacteria Source Load Calculator (BSLC) software is now available, along with a recently published user’s manual. The BSLC, developed by staff at the Center for TMDL and Watershed Studies, is designed to simplify the complex and time-consuming work involved in determining bacterial loadings necessary for input into many non-point source models including the Hydrological Simulation Program–Fortran model (HSPF). With new program features, such as allowing users to define in-stream defecation for specific days and species, BSLC users can more easily and accurately characterize the bacterial loads in watersheds.

Third-Party TMDL Development Tool KitA third-party TMDL is a TMDL in which an organization or group other than the lead water quality agency takes responsibility for developing the TMDL document and supporting analysis. A third party can be a watershed group, municipal wastewater or stormwater discharger organization, industrial discharger entity, other unit of government (such as a county, city, municipality, or land management agency), or nonpoint source organization (such as a farm bureau, irrigation and drainage district, or landowner).
Under a cooperative agreement with the U.S. Environmental Protection Agency, WEF has developed a Tool Kit for third-party TMDL development. Dr. Brian Benham, Director of the Center for TMDL and Watershed Studies at Virginia Tech participated on the task force that developed the tool kit.
