                       When a permit review is submitted for an absorption control solution, such data must be
                       supplied by the applicant to the appropriate regulatory authority. In this example, calcula-
                       tions are presented which will be used to confirm the applicant’s data. The following is a
                       typical data sheet used for an absorption project permit review:
                       A. Emission Stream Data
                          Hazardous Air Pollutant
                          1. Emission stream flow rate (maximum possible), Q =         acfm
                                                                     e
                          2. Temperature, T =              ºF

                          3. HAP =                (chemical name and formula)
                          4. HAP , HAP emission concentration =            ppmv
                                 e
                          5. Pressure, P =              mm Hg or inches of water
                                      e
                          6. RE, required removal efficiency =          %
                       B. Review Data for Permit Review (supplied by applicant)
