Sec. 60.293  Standards for particulate matter from glass melting furnace
with modified-processes.

    (a) An owner or operator of a glass melting furnaces with modified-
processes is not subject to the provisions of Sec. 60.292 if the 
affected facility complies with the provisions of this section.
    (b) On and after the date on which the performance test required to 
be conducted by Sec. 60.8 is completed, no owner or operator of a glass 
melting furnace with modified-processes subject to the provisions of 
this subpart shall cause to be discharged into the atmosphere from the 
affected facility:
    (1) Particulate matter at emission rates exceeding 0.5 gram of 
particulate per kilogram of glass produced (g/kg) as measured according 
to paragraph (e) of this section for container glass, flat

glass, and pressed and blown glass with a soda-lime recipe melting 
furnaces.
    (2) Particulate matter at emission rates exceeding 1.0 g/kg as 
measured according to paragraph (e) of this section for pressed and 
blown glass with a borosilicate recipe melting furnace.
    (3) Particulate matter at emission rates exceeding 0.5 g/kg as 
measured according to paragraph (e) of this section for textile 
fiberglass and wool fiberglass melting furnaces.
    (c) The owner or operator of an affected facility that is subject to 
emission limits specified under paragraph (b) of this section shall:
    (1) Install, calibrate, maintain, and operate a continuous 
monitoring system for the measurement of the opacity of emissions 
discharged into the atmosphere from the affected facility.
    (2) During the performance test required to be conducted by Sec. 
60.8, conduct continuous opacity monitoring during each test run.
    (3) Calculate 6-minute opacity averages from 24 or more data points 
equally spaced over each 6-minute period during the test runs.
    (4) Determine, based on the 6-minute opacity averages, the opacity 
value corresponding to the 99 percent upper confidence level of a normal 
distribution of average opacity values.
    (5) For the purposes of Sec. 60.7, report to the Administrator as 
excess emissions all of the 6-minute periods during which the average 
opacity, as measured by the continuous monitoring system installed under 
paragraph (c)(1) of this section, exceeds the opacity value 
corresponding to the 99 percent upper confidence level determined under 
paragraph (c)(4) of this section.
    (d)(1) After receipt and consideration of written application, the 
Administrator may approve alternative continuous monitoring systems for 
the measurement of one or more process or operating parameters that is 
or are demonstrated to enable accurate and representative monitoring of 
an emission limit specified in paragraph (b) of this section.
    (2) After the Administrator approves an alternative continuous 
monitoring system for an affected facility, the requirements of 
paragraphs (c) (1) through (5) of this section will not apply for that 
affected facility.
    (e) An owner or operator may redetermine the opacity value 
corresponding to the 99 percent upper confidence level as described in 
paragraph (c)(4) of this section if the owner or operator:
    (1) Conducts continuous opacity monitoring during each test run of a 
performance test that demonstrates compliance with an emission limit of 
paragraph (b) of this section,
    (2) Recalculates the 6-minute opacity averages as described in 
paragraph (c)(3) of this section, and
    (3) Uses the redetermined opacity value corresponding to the 99 
percent upper confidence level for the purposes of paragraph (c)(5) of 
this section.
    (f) Test methods and procedures as specified in Sec. 60.296 shall 
be used to determine compliance with this section except that to 
determine compliance for any glass melting furnace using modified 
processes and fired with either a gaseous fuel or a liquid fuel 
containing less than 0.50 weight percent sulfur, Method 5 shall be used 
with the probe and filter holder heating system in the sampling train 
set to provide a gas temperature of 120 14 [deg]C 
(248 25 [deg]F).
