                RULE 260.440.    APPLICABILITY AND DESIGNATION OF AFFECTED
                                 FACILITY

                (a)   The affected facility to which the provisions of this
           subpart apply is each coating line used in the manufacture of 
           pressure sensitive tape and label materials.

                (b)   Any affected facility which inputs to the coating 
           process 45 Mg (49.6 tons) of VOC or less per 12 month period is not 
           subject to the emission limits of Rule 260.442(a), however, the 
           affected facility is subject to the requirements of all other 
           applicable sections of this subpart.  If the amount of VOC input 
           exceeds 45 Mg per 12 month period, the coating line will become 
           subject to Rule 260.442(a) and all other sections of this subpart.

                (c)   This subpart applies to any affected facility which 
           begins construction, modification, or reconstruction after 
           December 30, 1980.

                RULE 260.442.    STANDARD FOR VOLATILE ORGANIC COMPOUNDS

                (a)   On and after the date on which the performance test 
           required by Rule 260.8 has been completed, each owner or operator 
           subject to this subpart shall:

                affected facility to be not more than 0.20 kg VOC/kg of 
                coating solids applied as calculated on a weighted average 
                basis for one calendar month; or

                      calendar month.


                RULE 260.443.    COMPLIANCE PROVISIONS

                (a)   To determine compliance with Rule 260.442 the owner or
           operator of the affected facility shall calculate a weighted 
           average of the mass of solvent used per mass of coating solids 
           applied for a one calendar month period according to the 
           following procedures:

                      (1)  Determine the weight fraction of organics and the
                weight fraction of solids of each coating applied by using EPA
                Reference Method 24 or by the coating manufacturer's 
                formulation data.

                      (2)  Compute the weighted average by the following 
                equation:
                                      
                                      n
                                           WoiMci
                                     i=1
                             G   =   -------------
                                      n
                                           WsiMci
                                     i=1

                    (3)  For each affected facility where the value of G is
               less than or equal to 0.20 kg VOC per kg of coating solids
               applied, the affected facility is in compliance with Rule
               260.442(a)(1).

               (b)  To determine compliance with rule 260.442(a)(2), the
          owner or operator shall calculate the required overall VOC
          emission reduction according to the following equation:

                                 G - 0.20
                    Rq    =      --------      x      100
                                    G

               If Rq is less than or equal to 90 percent, then the required
          overall VOC emission reduction is Rq.  If Rq is greater than 90
          percent, then the required overall VOC emission reduction is 90
          percent.

               (c)  Where compliance with the emission limits specified in
          Rule 260.442(a)(2) is achieved through the use of a solvent
          recovery system, the owner or operator shall determine the
          overall VOC emission reduction for a one calendar month period by
          the following equation:

                                         Mr
                    R         =  ---------------    x   100
                                   n
                                       WoiMci
                                  i=1

               If the R value is equal to or greater than the Rq value
          specified in Section (b) of this rule, then compliance with Rule
          260.442(a)(2) is demonstrated.

               (d)  Where compliance with the emission limit specified in
          Rule 260.442(a)(2) is achieved through the use of a solvent
          destruction device, the owner or operator shall  determine
          calendar monthly compliance by comparing the monthly required
          overall VOC emission reduction specified in Section (b) of this
          rule to the overall VOC emission reduction demonstrated in the
          most recent performance test which complied with Rule
          260.442(a)(2).  If the monthly required overall VOC emission
          reduction is less than or equal to the overall VOC reduction of
          the most recent performance test, the affected facility is in
          compliance with Rule 260.442(a)(2).

               (e)  Where compliance with Rule 260.442(a)(2) is achieved
          through the use of a solvent destruction device, the owner or
          operator shall continuously record the destruction device com-
          bustion temperature during coating operations for thermal
          incineration destruction devices or the gas temperature upstream
          and downstream of the incinerator catalyst bed during coating
          operations for catalytic incineration destruction devices.  For
          thermal incineration destruction devices the owner or operator
          shall record all 3-hour periods (during actual coating
          operations) during which the average temperature of the device is
          more than 10 C (50 F) below the average temperature of the
          device during the most recent performance test complying with
          Rule 260.442 (a)(2).  For catalytic incineration destruction
          devices, the owner or operator shall record all 3-hour periods
          (during actual coating operations) during which the average
          temperature of the device immediately before the catalyst bed is
          more than 10 C (50 F) below the average temperature of the
          device during the most recent performance test complying with
          Rule 260.442(a)(2), and all 3-hour periods (during actual coating
          operations) during which the average temperature difference
          across the catalyst bed is less than 80 percent of the average
          temperature difference of the device during the most recent
          performance test complying with Rule 260.442(a)(2).

               (f)  After the initial performance test required for all
          affected facilities under Rule 260.8, compliance with the VOC
          emission limitation and percentage reduction requirements under
          Rule 260.442 is based on the average emission reduction for one
          calendar month.  A separate compliance test is completed at the
          end of each calendar month after the initial performance test,
          and a new calendar month's average VOC emission reduction is
          calculated to show compliance with the standard.

               (g)  If a common emission control device is used to recover
          or destroy solvent from more than one affected facility, the
          performance of that control device is assumed to be equal for
          each of the affected facilities.  Compliance with Rule
          260.442(a)(3) is determined by the methods specified in Sections
          (c) and (d) of this rule and is performed simultaneously on all
          affected facilities.

               (h)  If a common emission control device is used to recover
          solvent from an existing facility (or facilities) as  well as
          from an affected facility (or facilities), the overall VOC
          emission reduction for the affected facility (or facilities), for
          the purpose of compliance, shall be determined by the following
          procedures:

                    (1)  The owner or operator of the existing facility (or
               facilities) shall determine the mass of solvent recovered
               for a calendar month period from the existing facility (or
               facilities) prior to the connection of the affected facility
               (or facilities) to the emission control device.

                    (2)  The affected facility (or facilities) shall then
               be connected to the emission control device.

                    (3)  The owner or operator shall determine the total
               mass of solvent recovered from both the existing and
               affected facilities over a calendar month period.  The mass
               of solvent determined in Subsection (h)(1) of this rule from
               the existing facility shall be subtracted from the total
               mass of recovered solvent to obtain the mass of solvent
               recovered from the affected facility (or facilities).  The
               overall VOC emission reduction of the affected facility (or
               facilities) can then be determined as specified in Section
               (c) of this rule.

               (i)  If a common emission control device is used to destruct
          solvent from an existing facility (or facilities) as well as from
          an affected facility (or facilities) the overall VOC emission
          reduction for the affected facility (or facilities), for the
          purpose of compliance, shall be determined by the following
          procedures:

                    (1)  The owner or operator shall operate the emission
               control device with both the existing and affected
               facilities connected.

                    (2)  The concentration of VOC (in parts per million by
               volume) after the common emission control device shall be
               determined as specified in Rule 260.444(c).  This concen-
               tration is used in the calculation of compliance for both
               the existing and affected facilities.

                    (3)  The volumetric flow out of the common control
               device attributable to the affected facility (or facilities)
               shall be calculated by first determining the ratio of the
               volumetric flow entering the common control device
               attributable to the affected facility (or facilities) to the
               total volumetric flow entering the common control device
               from both existing and affected facilities.  The
               multiplication of this ratio by the total volumetric flow
               out of the common control device yields the flow
               attributable to the affected facility (or facilities).
               Compliance is determined by the use of  the equation
               specified in Rule 260.444(c).

               (j)  Startups and shutdowns are normal operation for this
          source category.  Emissions from these operations are to be
          included when determining if the standard specified in Rule
          260.442(a)(2) is being attained.


               RULE 260.444.  PERFORMANCE TEST PROCEDURES

               (a)  The performance test for affected facilities complying
          with Rule 260.442 without the use of add-on controls shall be
          identical to the procedures specified in Rule 260.443(a).

               (b)  The performance test for affected facilities controlled
          by a solvent recovery device shall be conducted as follows:

                    (1)  The performance test shall be a one calendar month
               test and not the average of three runs as specified in Rule
               260.8(f).

                    (2)  The weighted average mass of VOC per mass of
               coating solids applied for a one calendar month period shall
               be determined as specified in Rules 260.443(a)(1) and
               260.443 (a)(2).

                    (3)  Calculate the required percent overall VOC
               emission reduction as specified in Rule 260.443(b).

                    (4)  Inventory VOC usage and VOC recovery for a one
               calendar month period.

                    (5)  Determine the percent overall VOC emission
               reduction as specified in Rule 260.443(c).

               (c)  The performance test for affected facilities controlled
          by a solvent destruction device shall be conducted as follows:

                    (1)  The performance of the solvent destruction device
               shall be determined by averaging the results of three test
               runs as specified in Rule 260.8(f).

                    (2)  Determine for each affected facility prior to each
               test run the weighted average mass of VOC per mass of
               coating solids applied being used at the facility.  The
               weighted average shall be determined as specified in Rule
               260.443(a).  In this application the quantities of Woi, Wsi,
               and Mi shall be determined for the time period of each test
               run and not a calendar month as specified in Rule 260.441.

                    (3)  Calculate the required percent overall VOC
               emission reduction as specified in Rule 260.443(b).

                    (4)  Determine the percent overall VOC emission
               reduction of the solvent destruction device by the following
               equation and procedures:

                              n                   m
                                  QbiCbi    -         QajCaj
                             i=1                 i=1
                     R   =   ---------------------------------    x   100
                              n                   p
                                  QbiCbi    +         QfkCfk
                             i=1                 i=1


                         (i)  The owner or operator of the affected
                    facility shall construct the overall VOC emission
                    reduction system so that all volumetric flow rates and
                    total VOC emissions can be accurately determined by the
                    applicable test methods and procedures specified in
                    Rule 260.446(b).

                         (ii) The owner or operator of an affected facility
                    shall construct a temporary total enclosure around the
                    coating line applicator and flashoff area during the
                    performance test for the purpose of capturing fugitive
                    VOC emissions.  If a permanent total enclosure exists
                    in the affected facility prior to the performance test
                    and the Control Officer is satisfied that the enclosure
                    is totally capturing fugitive VOC emissions, then no
                    additional total enclosure will be required for the
                    performance test.

                         (iii)For each affected facility where the value of
                    R is greater than or equal to the value of Rq
                    calculated in Rule 260.443(b), compliance with Rule
                    260.442(a)(2) is demonstrated.


               RULE 260.445.  MONITORING OF OPERATIONS AND
                              RECORDKEEPING

               (a)  The owner or operator of an affected facility, subject
          to this subpart shall maintain a calendar month record of all
          coatings used and the results the reference test method specified

          monitoring device shall have an accuracy of +0.75 percent of the
          temperature being measured expressed in degrees Celsius, or +2.5
          C, whichever is greater.

               (f)  The owner or operator of an affected facility
          controlled by a catalytic incineration solvent destruction device
          shall install, calibrate, maintain, and operate a monitoring
          device which continuously indicates and records the gas
          temperature both upstream and downstream of the catalyst bed.

               (g)  The owner or operator of an affected facility
          controlled by a solvent destruction device which uses a hood or
          enclosure to capture fugitive VOC emissions shall install,
          calibrate, maintain, and operate a monitoring device which
          continuously indicates that the hood or enclosure is oper-ating.
          No continuous monitor shall be required if the owner or operator
          can demonstrate that the hood or enclosure system is interlocked
          with the affected facility's oven recirculation air system.

               (h)  Records of the measurements required in Rules 260.443
          and 260.445 must be retained for at least two years following the
          dates of measurements.


               RULE 260.446.  TEST METHODS AND PROCEDURES

               Performance tests shall be conducted as specified in Part
          60, Chapter I, Title 40, Code of Federal Regulations, Section
          60.446.


               RULE 260.447.  REPORTING REQUIREMENTS  (Rev. Effective
          11/3/92)

               (a)  For all affected facilities subject to compliance with
          Rule 260.442, the performance test data and results from the
          performance test shall be submitted to the Control Officer as
          specified in Rule 260.8 (a) of the General Provisions (40 CFR
          Part 60, Subpart A).

               (b)  Following the initial performance test, the owner or
          operator of each affected facility shall submit quarterly
          reports, as specified in Rule 260.7(c), to the Control Officer of
          exceedances of the VOC emission limits specified in Rule 260.442.
          If no such exceedances occur during a particular quarter, a
          report stating this shall be submitted to the Control Officer
          semiannually.

               (c)  The owner or operator of each affected facility shall
          also submit reports semiannually to the Control Officer when the
          incinerator temperature drops as defined under Rule 260.443(e).
          If no such periods occur, the owner or operator shall state this
          in the report.

               (d)  The requirements of this rule shall remain in force
          until and unless EPA, the delegating enforcement authority to a
          State under Section 111(c) of the Act, approves reporting
          requirements or an alternative means of compliance surveillance
          adopted by such States.  In that event, affected sources within
          the State will be relieved of the obligation to comply with this
          rule, provided that they comply with the requirements established
          by the State.
