How do I calculate "Ozone Season to Date" and "Year to Date?"

Ozone Season to Date

To calculate Ozone Season to Date Total, sum the parameter value (i.e., emissions or time) from the beginning of the ozone season (May 1) to the end of the reporting period.

For a Q3 report, report the sum of the two quarterly parameter values for Ozone Season to Date Total for both Q2 and Q3.

For a Q4 report, report the parameter value for Ozone Season to Date Total from the Q3 report.

Year to Date

To calculate Year to Date Total for a Q1 report, simply report the sum parameter value (i.e., emissions or time) for the quarter.

For subsequent quarters, report the sum of the current reporting period plus the the quarterly values for the parameter reported in the previous quarters. For example, the Year to Date Total for Q3 would be calculated by summing the current Q3 reporting period value with the previously reported Q1 and Q2  values.
