  We describe the initial version of the Solar Particle Event (SPE) Threat
Assessment Tool or STAT. STAT relies on elements of Corona-Heliosphere (CORHEL)
and the Earth-Moon-Mars Radiation Environment Module (EMMREM), and allows users
to investigate coronal mass ejection (CME) driven SPEs using coupled
magnetohydrodynamic (MHD) and focused transport solutions. At the present time
STAT focuses on modeling solar energetic particle (SEP) acceleration in and
transport from the low corona, where the highest energy SEP events are
generated. We illustrate STAT's capabilities with a model of the July 14, 2000
"Bastille Day" event, including innovative diagnostics for understanding the
three-dimensional distribution of particle fluxes and their relation to the
structure of the underlying CME driver. A preliminary comparison with NOAA GOES
measurements is shown.
