(1) Demonstrate initial compliance by:
(i) Conducting emission tests using the methods specified in Table 3 of this subpart,
(ii) Using the results of a previously-conducted emission test as specified in paragraph (d) of this section; or

(iii) Using process knowledge and engineering calculations as specified in paragraph (f) of this section.
(d) If you are using a previously-conducted emission test to demonstrate compliance with the emission limitations in this subpart for existing sources, as specified in paragraphs (a)(1)(ii), (b)(1)(ii), or (c)(1)(ii) of this section, the following conditions must be met:
(1) The emission test was conducted within the last 5 years;
(2) No changes have been made to the process since the time of the emission test;
(3) The operating conditions and test methods used for the previous test conform to the requirements of this subpart; and
(4) The data used to establish the value or range of values of the operating parameters, as specified in paragraphs (a)(2)(ii), (b)(2)(ii), or (c)(2)(ii) of this section, were recorded during the emission test.
(e) If you are using process knowledge and engineering calculations to demonstrate initial compliance as specified in paragraph (c)(1)(iii) of this section, you must prepare written documentation that contains the data and any assumptions used to calculate the process emission rate that demonstrate compliance with the emission limits specified in Table 2 of this subpart.
(f) If you are using process knowledge and engineering calculations to establish the value or range of values of operating parameters as specified in paragraph (c)(2)(iii) of this section, you must prepare written documentation that contains the data and any assumptions used to show that the process parameters and corresponding parameter values correlate to the process emissions.
(g) For existing sources, you must demonstrate initial compliance no later than 180 calendar days after December 2, 2010.
(h) For new sources, you must demonstrate initial compliance no later than 180 calendar days after December 2, 2009 or within 180 calendar days after startup of the source, whichever is later.
(i) For emission tests conducted to demonstrate initial compliance with the emission limits specified in Tables 1 and 2 of this subpart, you must follow the requirements specified in paragraphs (i)(1) through (i)(4) of this section.
(1) You must conduct the tests while manufacturing the product that generates the greatest PAH and PM emissions to the control device inlet, or exiting the process if you are not using a control device to comply with the emissions limits specified in Tables 1 and 2 of this subpart.
(2) You must conduct a minimum of three separate test runs for each compliance test specified in paragraphs (a)(1)(i), (b)(1)(i), and (c)(1)(i) of this section according to the requirements specified in § 63.7(e)(3). The sampling time and sample volume of each test run must be as follows:
(i) For asphalt processing operations, the sampling time and sample volume for each test run must be 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).
(ii) For asphalt coating operations, the sampling time and sample volume for each test run must be at least 120 minutes and 3.00 dscm (106 dscf).
(3) For asphalt processing operations, you must use the following equations to calculate the asphalt charging rate (P).
(i) P = (Vd)/(K′ Θ)
Where:
P = asphalt charging rate to blowing still, Mg/hr (ton/hr).
V = volume of asphalt charged, m3 (ft3).
d = density of asphalt, kg/m3 (lb/ft3).
K′ = conversion factor, 1000 kg/Mg (2000 lb/ton).
Θ = duration of test run, hr.
(ii) d = K1−K2Ti
Where:
d = Density of the asphalt, kg/m3 (lb/ft3)
d = K1−K2Ti
K1 = 1056.1 kg/m3 (metric units)
= 66.6147 lb/ft3 (English Units)
K2 = 0.6176 kg/(m3 °C) (metric units)
= 0.02149 lb/(ft3 °F) (English Units)
Ti = temperature at the start of the blow, °C (°F)
(4) You must use the following equation to demonstrate compliance with the emission limits specified in Table 2 of this subpart:
E = [(C)*(Q)/(P)*(K)]
Where:
E = emission rate of particulate matter, kg/Mg (lb/ton).
C = concentration of particulate matter, g/dscm (gr/dscf).
Q = volumetric flow rate of effluent gas, dscm/hr (dscf/hr).
P = the average asphalt roofing production rate or asphalt charging rate over the duration of the test, Mg/hr (ton/hr).
K = conversion factor, 1000 g/kg [7000 (gr/lb)].
