tion shall provide to the Administrator 

information describing the operation 

of the control device and the process 

parameters) which would indicate 

proper operation and maintenance of 

the device. The Administrator may require continuous monitoring and will 

determine the process parameters to 

be monitored. 

(d) The industry is exempted from 

the quarterly reports required under 

160.7(c). The owner/operator is required to record and report the operating temperature of the control device 

during the performance test and, as 

required by | 60.7(d). maintain a file of 

the temperature monitoring results 

for at least two years. 

I §0.474 Test methods and procedure*. 

(a) For saturators. the owner or operator shall conduct performance tests 

required ln | 60.8 as follows: 

(1) If the final product is shingle or 

mineral-surfaced roll roofing, the tests 

shall be conducted while 106.6-kg (235 

lb) ahingie 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 ln 5 60.8. the owner or 

operator shall use as reference methods and procedures the test methods 

In appendix A of this part or othe r 

methods and procedures as specified 

ln this section, except as provided ln 

I 60.8(b). 

(c) The owner or operator shall determine compliance with the particulate matter standards in 160.472 as 

follows: 

(1) The emission rate (E) of particulate matter shall be computed for each 

run using the following equation: 

E-<c.Q-)/<PK) 

where: 

E-emission rate of particulate matter, kg/ 

Hg. 

C-concentration of particulate matter, g/ 

dscm (g/dscf). 

Q,,- volumetric flow rate of effluent gas. 

dscm/hr (dscf/hr). 

P~ asphalt roofing production rate or asphalt charging rate, afg/hr (ton/hr). 

40 CHI Ch. I (7-1-91 Edition) 

K = conversion factor. 1000 g/kg [907.2/(» 

Mg)/(kg-ton)l. 

(2) Method 5A shall be used to determine the particulate matter concentration (c.) and volumetric flow rate 

<Q*!> of the effluent gas. For a satura 

tor, 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 9o 

minutes or the duration of the coating 

blow or non-coating blow, whichever la 

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: 

T he 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'«) 

where: 

P - asphalt charging rate to blowing still, 

Mg/hr (ton/hr). 

V » volume of asphalt charged, m* (ft*), 

d-density of asphalt. kg/ma(Ub/ft1). 

K=- conversion factor. 1000 kg/nig (2000 lb/ 

ton). 

» = duration of test run. hr. 

(1) The volume (V) of asphalt 

charged shall be measured by any 

means accurate to within 10 percent. 

(ID The density (d) of the asphalt 

shall be computed using the following 

equation:

where: 

*C-temperature at the start of the blow. *C.

(5) Method 9 and the procedures In 

160.11 shall be used to determine 

opacity. 

(d) The Administrator will deter 

mine compliance with the standards in 

160.472(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 | 60.8(c)) totaling 60 minutes. A 

environmental Protection Agency 

performance teat shall consist of one 

run-

( e ) The owner or operator shall use 

the monitoring device Ln 8 60.473(a) or 

; t) to monitor and record continuously 

[ne temperature during the particulate matter run and shall report the 

results io the Administrator with the 

performance test results. 

(f) If at a later date the owner or operator believes the emission limits in 

160.472(a) and (b) are being me t even 

though the temperature measured in 

accordance with 160.473(a) and (b) is 

exceeding that measured during the 

performance test, he may submit a 

written request to the Administrator 

to repeat the performance test and 

procedure outlined ln paragraph (c) of 

this section. 

(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 160.11(e) of the 

Oeneral 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 ln 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.
