                   bases)  in  excess  of  120  grams of VOC per  liter  of
                   coating as applied.

          400 ADMINISTRATIVE REQUIREMENTS

              401  LABELING   REQUIREMENT:  DATE  OF   MANUFACTURE:    Each
                   container of  any  coating  subject  to  this rule shall
                   display  the  date of manufacture of the contents  or  a
                   code   indicating   the   date   of   manufacture.   The
                   manufacturer  of  such  coatings shall file with the Air
                   Pollution Control Officer  and  the Executive Officer of
                   the California Air Resources Board,  an  explanation  of
                   each code.

              402  LABELING  REQUIREMENT:  THINNING  RECOMMENDATIONS:  Each
                   container of any coating subject to  the requirements of
                   this   rule   shall   display   a   statement   of   the
                   manufacturer's recommendation regarding thinning  of the
                   coating.   This  requirement  shall  not  apply  to  the
                   thinning  of  architectural  coatings  with  water.  The
                   recommendation shall specify that the coating  is  to be
                   employed  without  thinning  or  diluting  under  normal
                   environmental  and  application  conditions,  unless the
                   recommended   thinning   for  normal  environmental  and
                   application conditions does  not  cause  the  coating to
                   exceed its applicable standard.

              403  LABELING REQUIREMENT: VOC CONTENT: Each container of any
                   coating  subject  to  this  rule  and manufactured after
                   October 2, 1991 shall display the maximum VOC content of
                   the  coating,  as  applied, and after  any  thinning  as
                   recommended by the manufacturer.   VOC  content shall be
                   displayed  as  grams  of VOC per liter of coating  (less
                   water and exempt compounds,  and  excluding any colorant
                   added  to  tint  bases).   For  low-solids  stains,  VOC
                   content shall be displayed as grams  of VOC per liter of
                   coating,   less  exempt  compounds  and  excluding   any
                   colorant added to tint bases.  VOC content displayed may
                   be calculated  using product formulation data, or may be
                   determined using the test method in Section 501.

              404  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  VOC  content shall
                   exclude  any  colorant  added  to  the tint bases.   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 209
                                                from the definition of VOC.
                                        
                                        Vm  = volume of coating material.
                                        
                                        Vw  = volume of water.
                                        
                                        Vec = volume of compounds listed as
                                        exempt in Section 209
                                                from the definition of VOC.

              405  CALCULATION FOR DETERMINATION OF  VOC CONTENT PER VOLUME
                   OF MATERIAL:  The volume of material  is  defined as the
                   volume of the original material, plus any VOC-containing
                   material  added to the original material.  The  original
                   material  is  the  material  before  any  VOC-containing
                   material such as solvent is added for purposes of mixing
                   or thinning.  The VOC content shall exclude any colorant
                   added to the  tint  bases.   The weight of VOC per total
                   volume of material shall be calculated  by the following
                   equation:

                                                    (Wv - Ww - Wec) / (Vm)

                               Where:   Wv    =  weight  of  all   volatile
                                        compounds.
                                        
                                        Ww  = weight of water.
                                        
                                        Wec = weight of compounds listed as
                                        exempt  in  Section 209        from
                                        the definition of VOC.
                                        
                                        Vm  = volume of material.
