Q613. Is there any way we can get unlocked subpart W screening spreadsheets from the applicability tool?

A613. No.  EPA’s intention in posting subpart W calculation utilities is to provide facilities with a simple tool for estimating emissions when determining applicability.  Additionally, the tools include a guidance and source tab to document how emission estimates were calculated.  The utilities are only a guide to help facilities determine their subpart W applicability.  If you suspect a facility may exceed the annual 25,000 metric ton CO2e threshold, you should refer to the calculation methodologies in 98.233 to determine emissions.
