                   coatings used at the stationary  source  does not exceed
                   200 gallons in the continuous twelve (12)  month  period
                   designated pursuant to Section 401.3.i.

              111  EXEMPTION,   SPECIFIC   OPERATIONS  AND  COATINGS:   The

          200 DEFINITIONS

              201  ABLATIVE COATING:  A coating, applied to  both  new  and
                   rework  aerospace  components,  which  chars and becomes
                   intumescent when exposed to open flame,  such  as  would
                   occur  during  the  failure  of  an  engine casing.  The
                   purpose  of  the  coating  is  to  act as an  insulative
                   barrier and protect adjacent metal parts  from  an  open
                   flame.

              202  ADHESIVE:   A  coating  applied  either over an adhesive
                   bonding agent, or directly to the  substrate,  on two or
                   more  aerospace  components to provide a permanent  bond
                   between the components.

              203  ADHESIVE BONDING AGENT (PRIMER):  A coating applied in a
                   thin  film  (.0001 to  .0005  inches)  to  two  or  more
                   aerospace components  that are  subsequently coated with
                   an adhesive.  The purpose  of  the agent is to provide a
                   slight etching of the surface and ensure the strength of
                   the adhesive bond.

              204  AEROSPACE COMPONENT:  The fabricated  part,  assembly of
                   parts,  or  completed  unit  of  any  aircraft  or space
                   vehicle.

              205  AIRCRAFT:   Any  vehicle designed to travel through  the
                   air without leaving  the  Earth's  atmosphere, including

                   miles above the surface of the Earth.

              207  CLEANUP  MATERIAL:  A VOC-containing  material  used  to
                   clean application  equipment  used  in aerospace coating
                   operations.

              208  COATING:  A material applied to a surface  to  identify,
                   beautify,   protect,   or  minimize  detection  of  such
                   surface.

              209  COATING LINE:  Any operation  or  process  for applying,
                   baking,  curing,  or  drying surface coatings,  together
                   with associated equipment, such as a coating applicator,
                   flashoff area, and oven.

              210  CONFORMAL  COATING:   A coating  applied  to  electronic
                   circuit  boards  or  the assembled  components  for  the
                   resistance of moisture, corrosion, bacteria, or fungi.

              211  ELECTROSTATIC  DISCHARGE   COATING:    An   electrically
                   conductive coating which prevents the build-up of static
                   charge   on  the  surface  of  an  aerospace  component.
                   Applications   include,   but   are   not   limited  to,
                   composites,   space  vehicles  (shuttle  craft  rework),
                   missiles, or helicopter blades.

              212  ENCLOSED GUN CLEANER:  A  device  that  is  used for the
                   cleaning  of spray guns that is not open to the  ambient
                   air when in use and has a mechanism to force the cleanup
                   material  through  the  gun  while  the  cleaner  is  in
                   operation.

              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
                   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 213
                                        from the definition of VOC.
                                        
                                        Vm  = volume of coating material.
                                        
                                        Vw  = volume of water.
                                        
                                        Vec = volume of compounds listed as
                                        exempt in Section 213
                                        from the definition of VOC.
