This spreadsheet program was developed to assist in
determining the cancer and non-cancer health effects pursuant to Rule 1401
Risk Assessment Procedures for Rules 1401 and 212, Version 7.0.
The spreadsheet program also includes specific modules
for boilers and internal combustion engines fired by natural gas and for
diesel internal combustion engines. These incorporate an alternative set of dispersion
factors (X/Q) for Tier 2 Analysis (see explanation on Page 14 of the
Risk
Assessment Procedures Version 7.0 document). The spreadsheet
program has been modified so that results from dispersion analysis using
EPA’s SCREEN program can be entered into the spreadsheet to calculate the
risks.
The following files are presented to assist you with
the calculations:
