                                 PROVISIONS

                (a)   Rule 260.8(d) and 260.8(f) do not apply to the 
           performance test procedures required by this subpart.

                (b)   The owner or operator of an affected facility shall 
           conduct an initial performance test as required under Rule 260.8(a) 
           and thereafter a performance test each calendar month for each 
           affected facility according to the procedures in this rule.

                (c)   The owner or operator shall use the following procedures 
           for determining monthly volume-weighted average emissions of VOC's 
           in kilograms per liter of coating solids applied (G).

                      (1)  An owner or operator shall use the following 
                procedures for any affected facility which does not use a 
                capture system and control device to comply with the emissions 
                limit specified under Rule 260.312.  The owner or operator 
                shall determine the composition of the coatings by formulation 
                data supplied by the manufacturer of the coating or by an 
                analysis of each coating, as received, using Reference Method 
                24.  The Control Officer may require the owner or operator who 
                uses formulation data supplied by the manufacturer of the 
                coating to determine the VOC content of coatings using 
                Reference Method 24.  The owner or operator shall determine 
                the volume of coating and the mass VOC-solvent used for 
                thinning purposes from company records on a monthly basis.  
                If a common coating distribution system serves more than one 
                affected facility or serves both affected and existing 
                facilities, the owner or operator shall estimate the volume of 
                coating used at each facility by using the average dry weight 
                of coating and the surface area coated by each affected and 
                existing facility or by other procedures acceptable to the 
                Control Officer.

                           (i)   Calculate the volume-weighted average of the

                      solids applied (G) during each calendar month for each
                      affected facility, except as provided under Rule
                      260.313(c)(2) and (c)(3).  Each monthly calculation is
                      considered a performance test.  Except as provided in
                      Subsection (c)(1)(iv) of this rule, the volume-weighted
                      average of the total mass of VOC's consumed per unit 
                      volume of coating solids applied (G) each calendar month 
                      will be determined by the following procedures.

                           (Mo + Md) during each calendar month for each 
                           affected facility by the following equation:

                                           n                    m
                           Mo  +  Md   =      Lci Dci Woi  +      Ldj Ddj

                        (LdjDdj will be 0 if no VOC solvent is added to
                        the coatings, as received.)

                    Where:  n is the number of different coatings used
               during the calendar month and m is the number of different
               diluent VOC-solvents used during the calendar month.

                    (B)  Calculate the total volume of coating solids used
               (Ls) in each calendar month for each affected facility by
               the following equation:

                                   Ls  =     Lci Vsi
                                         i=1

               Select the appropriate transfer efficiency from Table 1.  If
          the owner or operator can demonstrate to the satisfaction of the
          Control Officer that other transfer efficiencies other than those
          shown are appropriate, the Control Officer will approve their use
          on a case-by-case basis.  Transfer efficiency values for
          application methods not listed below shall be determined by the
          Control Officer on a case-by-case basis.  An owner or operator
          must submit sufficient data for the Control Officer to judge the
          accuracy of the transfer efficiency claims.

                    Where more than one application method is used within a
               single surface coating operation, the owner or operator
               shall determine the composition and volume of each coating
               applied by each method through a means acceptable to the
               Control Officer and compute the weighted average transfer
               efficiency by the following equation:

                    solids applied (N) is less than or equal to 0.90
                    kilogram per liter, the affected facility is in
                    compliance.

                    affected facility has a VOC content, as received, which
                    when divided by the lowest transfer efficiency at which
                    the coating is applied, results in a value equal to or
                    less than 0.90 kilogram per liter, the affected
