                 materials  added  to  the original coating supplied  by  the
                 manufacturer
                             
           Ww  = Weight of water
                             
           Wec = Weight of exempt compounds as listed in Section 210
                             
           Vm  = Volume of coating material
             
           Vw  = Volume of water
             
           Vec = Volume of exempt compounds as listed in Section 210


 407  OPERATION AND MAINTENANCE PLAN:  Any  person  using an approved emission
      control device pursuant to Section 304 as a means of complying with this
      rule, as provided in Section 301, must submit,  with the application for
      Authority   to   Construct,   pursuant  to  Rule  201,  General   Permit
      Requirements, an Operation and Maintenance Plan for the emission control
      device to the Air Pollution Control  Officer  for  approval.   Plans for
      emission  control  devices  installed  as  of  February 23, 1993, if not
      previously  submitted,  must be submitted August 23,  1993  and  receive
      approval of the Air Pollution  Control  Officer.  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  501.3 and 501.4.
      The Plan shall be implemented upon approval of the Air Pollution Control
      Officer.
