Criteria Calculation Spreadsheets
The following downloadable Excel spreadsheets can be used to help understand how the criteria have been calculated. The formulas and inputs can be found in the Technical Support Documents above and in the 40 CFR Part 132. Spreadsheets include default settings as published in 40 CFR Part 132. Please note: States and Tribes may use different values and equations from what has been published by the EPA, see specific State and Tribal regulatory languages to determine how values are calculated.
