Central Registry Toolbox Code Version(s): V7.0
Code Owner: Homann Associates, Inc.
Description: The Emergency Prediction Information code, or EPIcode, program was developed to provide emergency response personnel and emergency planners with a software tool to help evaluate the atmospheric release of toxic substances. EPIcode allows fast estimation and assessment of chemical release scenarios associated with accidents from industry and transportation. The software can also be used for safety analysis planning purposes on facilities handling toxic materials. EPIcode performs calculations for chemical source terms and resulting downwind concentrations. Source term calculations determine the rate at which the chemical material is released to the atmosphere, release height, release durations, and the form and properties of the chemical upon release. The release chemical may be a gas, a vapor, or an aerosol.
In May 2004, the DOE performed an evaluation of EPIcode against DOE's safety software quality assurance criteria. A gap analysis report was generated that identifies the strengths and weaknesses based upon ASME NQA-1 criteria. Upon completion of this evaluation, EPIcode V7.0 was included in DOE's safety software Central Registry as a safety analysis toolbox code. Inclusion into DOE's safety software Central Registry provides to DOE sites knowledge of the pedigree of the safety software quality assurance (SSQA) level for EPIcode V7.0. If another version of EPIcode is used, DOE sites must assume the responsibility to determine that the quality assurance level meets DOE SSQA requirements. DOE published guidance for the use of EPIcode. This guidance is recommended for all DOE applications of EPIcode V7.0
