          400 ADMINISTRATIVE REQUIREMENTS

              401  OPERATION  AND  MAINTENANCE PLAN: Any facility using  an
                   emission control  device  as  a  means of complying with
                   this rule, as provided in Section  302, must submit with
                   the application for Authority to Construct  and resubmit
                   annually,   upon  completion  of  construction  of   the
                   emission control  device,  an  Operation and Maintenance
                   Plan  for  the  emission  control  device   to  the  Air
                   Pollution Control Officer for approval.  The  Plan shall
                   specify operation and maintenance procedures which  will
                   demonstrate continuous operation of the emission control
                   device during periods of emissions-producing operations.
                   The  Plan  shall also specify which records must be kept
                   to document  these operation and maintenance procedures.
                   These records  shall  comply  with  the  requirements of
                   Sections  504  and  505.   The Plan shall be implemented
                   upon approval of the Air Pollution Control Officer.

              402  CALCULATION FOR DETERMINATION  OF VOC CONTENT PER VOLUME
                   OF COATING:  The volume of coating  material  is defined
                   as  the  volume  of the original coating, plus any  VOC-
                   containing material  added to the original coating.  The
                   original  coating  is  the   coating   before  any  VOC-
                   containing  material  such  as  solvent  is  added   for
                   purposes  of  mixing or thinning.  The weight of VOC per
                   combined volume  of  VOC  and  coating  solids, shall be
                   calculated by the following equation:

                                   (Wv - Ww - Wec) / (Vm - Vw - Vec)

                               Where:   Wv    =  weight  of  all   volatile
                                        compounds.
                                        
                                        Ww  = weight of water.
                                        
                                        Wec = weight of compounds listed as
                                        exempt in Section 204
                                        from the definition of VOC.
                                        
                                        Vm  = volume of coating material.
                                        
                                        Vw  = volume of water.
                                        
                                        Vec = volume of compounds listed as
                                        exempt in Section 204
                                        from the definition of VOC.
