§591-B. Meteorological data collection
1.
Data requirements.
A minimum of one year of acceptable on-site meteorological data is required for any modeling analysis. If more than one year of on-site data is available, all acceptable data must be used, up to a maximum of 5 years of data. If less than 5 consecutive years of acceptable on-site data is available, the source must continue to collect meteorological data to obtain an acceptable 5-year data base. Acceptable data means that the data meets the department's requirements based on the federal Environmental Protection Agency's guidelines on air quality models.
