Sec. 60.474  Test methods and procedures.

    (a) For saturators, the owner or operator shall conduct performance 
tests required in Sec. 60.8 as follows:
    (1) If the final product is shingle or mineral-surfaced roll 
roofing, the tests

[[Page 500]]

shall be conducted while 106.6-kg (235-lb) shingle is being produced.
    (2) If the final product is saturated felt or smooth-surfaced roll 
roofing, the tests shall be conducted while 6.8-kg (15-lb) felt is being 
produced.
    (3) If the final product is fiberglass shingle, the test shall be 
conducted while a nominal 100-kg (220-lb) shingle is being produced.
    (b) In conducting the performance tests required in Sec. 60.8, the 
owner or operator shall use as reference methods and procedures the test 
methods in appendix A of this part or other methods and procedures as 
specified in this section, except as provided in Sec. 60.8(b).
    (c) The owner or operator shall determine compliance with the 
particulate matter standards in Sec. 60.472 as follows:
    (1) The emission rate (E) of particulate matter shall be computed 
for each run using the following equation:

E=(cs Qsd)/(PK)

where:

E=emission rate of particulate matter, kg/Mg (lb/ton).
cs=concentration of particulate matter, g/dscm (gr/dscf).
Qsd=volumetric flow rate of effluent gas, dscm/hr (dscf/hr).
P=asphalt roofing production rate or asphalt charging rate, Mg/hr (ton/
hr).
K=conversion factor, 1000 g/kg [7000 (gr/lb)].

    (2) Method 5A shall be used to determine the particulate matter 
concentration (cs) and volumetric flow rate (Qsd) 
of the effluent gas. For a saturator, the sampling time and sample 
volume for each run shall be at least 120 minutes and 3.00 dscm (106 
dscf), and for the blowing still, at least 90 minutes or the duration of 
the coating blow or non-coating blow, whichever is greater, and 2.25 
dscm (79.4 dscf).
    (3) For the saturator, the asphalt roofing production rate (P) for 
each run shall be determined as follows: The amount of asphalt roofing 
produced on the shingle or saturated felt process lines shall be 
obtained by direct measurement. The asphalt roofing production rate is 
the amount produced divided by the time taken for the run.
    (4) For the blowing still, the asphalt charging rate (P) shall be 
computed for each run using the following equation:

P=(Vd)/(K' [thetas])

where:

P=asphalt charging rate to blowing still, Mg/hr (ton/hr).
V=volume of asphalt charged, m\3\ (ft\3\).
d=density of asphalt, kg/m\3\ (lb/ft\3\).
K'=conversion factor, 1000 kg/Mg (2000 lb/ton).
[thetas]=duration of test run, hr.

    (i) The volume (V) of asphalt charged shall be measured by any means 
accurate to within 10 percent.
    (ii) The density (d) of the asphalt shall be computed using the 
following equation:
[GRAPHIC] [TIFF OMITTED] TR17OC00.015

Where:

d = Density of the asphalt, kg/m\3\ (lb/ft\3\)
K1 = 1056.1 kg/m\3\ (metric units)
    = 64.70 lb/ft\3\ (English Units)
K2 = 0.6176 kg/(m\3\ [deg]C) (metric units)
    = 0.0694 lb/(ft\3\ [deg]F) (English Units)
Ti = temperature at the start of the blow, [deg]C ( [deg]F)

    (5) Method 9 and the procedures in Sec. 60.11 shall be used to 
determine opacity.
    (d) The Administrator will determine compliance with the standards 
in Sec. 60.472(a)(3) by using Method 22, modified so that readings are 
recorded every 15 seconds for a period of consecutive observations 
during representative conditions (in accordance with Sec. 60.8(c)) 
totaling 60 minutes. A performance test shall consist of one run.
    (e) The owner or operator shall use the monitoring device in Sec. 
60.473 (a) or (b) to monitor and record continuously the temperature 
during the particulate matter run and shall report the results to the 
Administrator with the performance test results.
    (f) If at a later date the owner or operator believes that the 
emission limits in Sec. 60.472(a) and (b) are being met even though one 
of the conditions listed in this paragraph exist, he may submit a 
written request to the Administrator to repeat the performance test and 
procedure outlined in paragraph (c) of this section.
    (1) The temperature measured in accordance with Sec. 60.473(a) is 
exceeding that measured during the performance test.
    (2) The temperature measured in accordance with Sec. 60.473(b) is 
lower than

[[Page 501]]

that measured during the performance test.
    (g) If fuel oil is to be used to fire an afterburner used to control 
emissions from a blowing still, the owner or operator may petition the 
Administrator in accordance with Sec. 60.11(e) of the General 
Provisions to establish an opacity standard for the blowing still that 
will be the opacity standard when fuel oil is used to fire the 
afterburner. To obtain this opacity standard, the owner or operator must 
request the Administrator to determine opacity during an initial, or 
subsequent, performance test when fuel oil is used to fire the 
afterburner. Upon receipt of the results of the performance test, the 
Administrator will make a finding concerning compliance with the mass 
standard for the blowing still. If the Administrator finds that the 
facility was in compliance with the mass standard during the performance 
test but failed to meet the zero opacity standard, the Administrator 
will establish and promulgate in the Federal Register an opacity 
standard for the blowing still that will be the opacity standard when 
fuel oil is used to fire the afterburner. When the afterburner is fired 
with natural gas, the zero percent opacity remains the applicable 
opacity standard.
