A)        Selection of simulation model: i)          Gaussian models that allow the input of hourly meteorological data must be used which are appropriate for the specific location and type of source or sources in question. ii)         Dispersion models presented in "Guidelines on Air Quality Models" (EPA-450/2-78-027), or those deemed by the Board to be equivalent to these models must be used for detailed air quality studies. B)        Selection of meteorological data and stack parameters: i)          The most recent 5 years of hour-by-hour meteorological data reasonably available, including wind speed, wind direction, atmospheric stability, mixing height and surface temperature must be used, unless the petitioner demonstrates that one of the 5 years causes substantially higher concentrations than the other four, in which case detailed analyses conducted for only that "worst case" year would be acceptable.  Notwithstanding the previous sentence, one year of on-site data may be used in lieu of the 5-year data requirement; ii)         Data must be from the nearest, representative, quality controlled meteorological collecting site; and iii)        Stack parameters (including emission rate, stack height, stack diameter, exit velocity, and exit temperature) must reflect the maximum operating rate for comparison with the 24-hour and 3-hour sulfur dioxide standards. C)        Receptors: i)          Receptors must be located so as to ensure that the source's maximum impact is detected; and ii)         The determination of the receptor grid must be fully documented in the modeling study; D)        Special conditions: i)          All special conditions that may affect the dispersion of the effluent plume, including local terrain effects and aerodynamic downwash, must be considered in the modeling study; ii)         If terrain is a factor in the vicinity of the source, a model capable of handling variable-height receptors must be used; and iii)        If the computed height of the effluent plume is less than 2.5 times the height of nearby buildings or local obstructions, aerodynamic downwash must be studied and considered as a possible factor in the dispersion of that effluent. E)        Determination of violation:  The determination of whether an applicable air quality increment or standard is being violated must be based on the second-highest predicted concentration over the receptor grid for short-term averaging times and on the highest predicted concentration for annual averaging times. However, if only one year of meteorological data is used in the short-term analysis, then the highest predicted concentration may be compared to the applicable standard to determine whether a violation has occurred. F)         Other sources:  Effects of other sources of sulfur dioxide must be taken into account in the modeling study.  Methods by which other sources of sulfur dioxide may be accounted are as follows: i)          An acceptable method is to estimate the "background" from monitoring data which has been subjected to adequate quality control where available.  When monitored data is used, the background must be estimated using monitoring days with meteorological conditions similar to those identified as "worst case" for the source in question; or ii)         If monitoring data is not available, then all sources of sulfur dioxide having a significant impact in the area of the source's impact area must be used in the simulation model.  These sources of sulfur dioxide must also be modeled at their maximum allowable emission rate for any studies addressing 24-hour or 3-hour averaging times. 8)         Estimates of the frequency, characteristics, probable time of occurrence, and duration of the meteorological conditions associated with the maximum ground-level concentration of sulfur dioxide to which the facility under study contributes.  A description of the techniques used in arriving at the above estimates must be included. 9)         Background concentrations that were determined for all meteorological conditions required to be examined under subsection (c)(7) and for any other meteorological conditions considered in the development of the alternative standard. 10)         A description of the method that was used to determine background sulfur dioxide concentrations in the vicinity of the subject facility for each of the meteorological conditions required to be examined under subsection (c)(7) and for any additional meteorological conditions considered in developing the alternative standard. 11)         An evaluation and calibration of the dispersion model if air quality monitoring data were available to perform the evaluation and calibration. 12)         A statement that the procedural requirements of 40 CFR 51.4 (1977) are met. At least 30 days prior to the date of the hearing, the petitioner must: A)        Give notice to the public, by prominent advertisement in the Air Quality Control Region affected, announcing the date, time, and place of the hearing; B)        Make available a copy of the petition for public inspection in at least one location in the Air Quality Control Region in which the source is located; C)        Notify the Administrator of USEPA (through the Region V Office); D)        Notify each local air pollution control agency located within the affected Air Quality Control Region; and E)        Notify, in the case of an interstate Air Quality Control Region, any air pollution control agencies of other states included, in whole or in part, in the Region.
