          SUBPART FFF -  Standards of Performance for Flexible Vinyl and
                         Urethane Coating and Printing   (Delegation 
                         Effective 3/19/87)


                RULE 260.580.    APPLICABILITY AND DESIGNATION OF AFFECTED
                                 FACILITY

                (a)   The affected facility to which the provisions of this
           subpart apply is each rotogravure printing line used to print or 
           coat flexible vinyl or urethane products.

                (b)   This subpart applies to any affected facility which 
           begins construction, modification, or reconstruction after 
           January 18, 1983.

                (c)   For facilities controlled by a solvent recovery 
           emission control device, the provisions of Rule 260.584(a) 
           requiring monitoring of operations will not apply until EPA has 
           promulgated performance specifications under Appendix B for the 
           continuous monitoring system.  After the promulgation of 
           performance specifications, these provisions will apply to each 
           affected facility under Section (b) of this rule.  Facilities 
           controlled by a solvent recovery emission control device that 
           become subject to the standard prior to promulgation of
           performance specifications must conduct performance tests in 
           accordance with Rule 260.13(b) after performance specifications are 
           promulgated.


                RULE 260.581.    DEFINITIONS

                All terms used in this subpart, not defined below, are given

                RULE 260.584.    MONITORING OF OPERATIONS AND RECORD-
                                 KEEPING REQUIREMENTS

                (a)   The owner or operator of an affected facility controlled 
           by a solvent recovery emission control device shall install, 
           calibrate, operate, and maintain a monitoring system which 
           continuously measures and records the VOC concentration of the 
           exhaust vent stream from the control device and shall comply with 
           the following requirements:

                      (1)  The continuous monitoring system shall be installed 
                in a location that is representative of the VOC concentration 
                in the exhaust vent, at least two equivalent stack diameters 
                from the exhaust point, and protected from interferences due 
                to wind, weather, or other processes.

                      (2)  During the performance test, the owner or operator
                shall determine and record the average exhaust vent VOC
                concentration in parts per million by volume.  After the per-
                formance test, the owner or operator shall determine and, in
                addition to the record made by the continuous monitoring 
                device, record the average exhaust vent VOC concentration for 
                each 3-hour clock period of printing operation when the 
                average concentration is greater than 50 ppm and more than 20 
                percent greater than the average concentration value 
                demonstrated during the most recent performance test.

                (b)   The owner or operator of an affected facility controlled 
           by a thermal incineration emission control device shall install,
           calibrate, operate, and maintain a monitoring device that 
           continuously measures and records the temperature of the control 
           device exhaust gases and shall comply with the following 
           requirements:

                      (1)  The continuous monitoring device shall be 
                calibrated annually and have an accuracy of 0.75 percent of 
                the temperature being measured or 2.5C, whichever is 
                greater.

                      (2)  During the performance test, the owner or operator
                shall determine and record the average temperature of the 
                control device exhaust gases.  After the performance test, the 
                owner or operator shall determine and record, in addition to 
                the record made by the continuous monitoring device, the 
                average temperature for each 3-hour clock period of printing 
                operation when the average temperature of the exhaust gases is 
                more than 28C below the average temperature demonstrated 
                during the most recent performance test.

                (c)   The owner or operator of an affected facility controlled 
           by a catalytic incineration emission control device shall install,
           calibrate, operate, and maintain monitoring devices that 
           continuously measure and record the gas temperatures both upstream 
           and downstream of the catalyst bed and shall comply with the 
           following requirements.

                      (1)  Each continuous monitoring device shall be 
                calibrated annually and have an accuracy of +0.75 percent of 
                the temperature being measured or +2.5C, whichever is 
                greater.

                      (2)  During the performance test, the owner or operator
                shall determine and record the average gas temperature both
                upstream and downstream of the catalyst bed.  After the
                performance test, the owner or operator shall determine and
                record, in addition to the record made by the continuous
                monitoring device, the average temperatures for each 3-hour 
                clock period of printing operation when the average 
                temperature of the gas stream before the catalyst bed is more 
                than 28C below the average temperature demonstrated during 
                the most recent performance test or 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.

                (d)   The owner or operator of an affected facility shall 
           record time periods of operation when an emission control device is 
           not in use.

                RULE 260.585.    REPORTING REQUIREMENTS

                (a)   For all affected facilities subject to compliance with 
           Rule 260.582, the performance test data and results from the 
           performance test shall be submitted to the Control Officer as 
           specified in Rule 260.8(a).

                (b)   The owner or operator of each affected facility shall 
           submit semiannual reports to the Control Officer of occurrences of 
           the following:

                      (1)  Exceedances of the weighted average VOC content
                specified in Rule 260.582(a)(1);

                      (2)  Exceedances of the average value of the exhaust 
                vent VOC concentration as defined under Rule 260.584(a)(2);

                      (3)  Drops in the incinerator temperature as defined in 
                Rule 260.584(b)(2); and

                      (4)  Drops in the average temperature of the gas stream
                immediately before the catalyst bed or drops in the average
                temperature across the catalyst bed as defined under Rule
                260.584(c)(2).

                (c)   The reports required under Section (b) of this rule 
           shall be postmarked within 30 days following the end of the second 
           and fourth calendar quarters.

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