BASINS 4.0 Climate Assessment Tool (CAT): Supporting 
Documentation and Users Manual

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of public comment period.

-----------------------------------------------------------------------

SUMMARY: EPA is announcing a 30-day public comment period for the draft 
document titled, ``BASINS 4.0 Climate Assessment Tool (CAT): Supporting 
Documentation and Users Manual'' (EPA/600/R-08/088). The document was 
prepared by the National Center for Environmental Assessment within 
EPA's Office of Research and Development.
    The Office of Research and Development, in partnership with EPA's 
Office of Water, recently developed a Climate Assessment Tool (CAT) for 
the Office of Water's BASINS 4.0 watershed modeling system. BASINS CAT 
provides a flexible set of capabilities for creating user-defined 
climate change scenarios for assessing the influence of climate 
variability and change on water quantity and quality using the 
Hydrologic Simulation Program--FORTRAN (HSPF) watershed model. This 
report provides documentation and technical user support including a 
discussion of tool capabilities with hands-on tutorials demonstrating 
the application of BASINS CAT to a range of problems. BASINS 4.0 (with 
the BASINS CAT) can be downloaded from EPA's BASINS Web site at http://
www.epa.gov/waterscience/basins/b3webdwn.htm.
    EPA is releasing this draft document solely for the purpose of pre-
dissemination peer review under applicable information quality
