It is recommended that episodes for modeling be selected from

the period from 1987 to the present time. Selected episodes

should represent different meteorological regimes observed to

correspond with ozone >0.12 ppm (as described above). When

selecting episodes, both stagnation and transport conditions

should be examined. A minimum of 3 primary episode days

should be simulated.

Primary episode days falling within each meteorological regime

are ranked according to the highest observed daily maximum

ozone concentration measured within or near the nonattainment

CMSA/MSA. Episodes may be chosen to include any of the three

top-ranked days in each regime. In addition to considering

the magnitude of the highest observed daily maximum ozone

concentration in making this choice, data availability and

quality, model performance, availability of regional modeling

analyses, pervasiveness, frequency with which observed

meteorological conditions coincide with exceedances, and

duration of observations >0.12 ppm may be considered.

Other techniques for selecting episodes should be described in

the Protocol Document and approved by the appropriate EPA

Regional Office.
