Sec. 60.275  Test methods and procedures.

    (a) During performance tests required in Sec. 60.8, the owner or 
operator shall not add gaseous diluent to the effluent gas after the 
fabric in any pressurized fabric collector, unless the amount of 
dilution is separately determined and considered in the determination of 
emissions.
    (b) When emissions from any EAF(s) are combined with emissions from 
facilities not subject to the provisions of this subpart but controlled 
by a common capture system and control device, the owner or operator 
shall use either or both of the following procedures during a 
performance test (see also Sec. 60.276(b)):
    (1) Determine compliance using the combined emissions.
    (2) Use a method that is acceptable to the Administrator and that 
compensates for the emissions from the facilities not subject to the 
provisions of this subpart.
    (c) When emissions from any EAF(s) are combined with emissions from 
facilities not subject to the provisions of this subpart, the owner or 
operator shall use either or both of the following procedures to 
demonstrate compliance with Sec. 60.272(a)(3):
    (1) Determine compliance using the combined emissions.
    (2) Shut down operation of facilities not subject to the provisions 
of this subpart during the performance test.
    (d) 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).
    (e) The owner or operator shall determine compliance with the 
particulate matter standards in Sec. 60.272 as follows:
    (1) Method 5 shall be used for negative-pressure fabric filters and 
other types of control devices and Method 5D shall be used for positive-
pressure fabric filters to determine the particular matter concentration 
and, if applicable, the volumetric flow rate of the effluent gas. The 
sampling time and sample volume for each run shall be at least 4 hours 
and 4.5 dscm (160 dscf) and, when a single EAF is sampled, the sampling 
time shall include an integral number of heats.
    (2) When more than one control device serves the EAF(s) being 
tested, the concentration of particulate matter shall be determined 
using the following equation:

where:

cst=average concentration of particulate matter, mg/dscm (gr/
dscf).
csi=concentration of particulate matter from control device 
``i'', mg/dscm (gr/dscf).
n=total number of control devices tested.
Qsdi=volumetric flow rate of stack gas from control device 
``i'', dscm/hr (dscf/hr).

    (3) Method 9 and the procedures of Sec. 60.11 shall be used to 
determine opacity.
    (4) To demonstrate compliance with Sec. 60.272(a) (1), (2), and 
(3), the Method 9 test runs shall be conducted concurrently with the 
particulate matter test runs, unless inclement weather interferes.
    (f) To comply with Sec. 60.274 (c), (f), (g), and (i), the owner or 
operator shall obtain the information in these paragraphs during the 
particulate matter runs.
    (g) Where emissions from any EAF(s) are combined with emissions from 
facilities not subject to the provisions of this subpart but controlled 
by a common capture system and control device, the owner or operator may 
use any of the following procedures during a performance test:
    (1) Base compliance on control of the combined emissions.
    (2) Utilize a method acceptable to the Administrator which 
compensates for the emissions from the facilities not subject to the 
provisions of this subpart.
    (3) Any combination of the criteria of paragraphs (g)(1) and (g)(2) 
of this section.
    (h) Where emissions from any EAF(s) are combined with emissions from 
facilities not subject to the provisions of this subpart, the owner or 
operator may use any of the following procedures for demonstrating 
compliance with Sec. 60.272(a)(3):

[[Page 410]]

    (1) Base compliance on control of the combined emissions.
    (2) Shut down operation of facilities not subject to the provisions 
of this subpart.
    (3) Any combination of the criteria of paragraphs (h)(1) and (h)(2) 
of this section.
    (i) If visible emissions observations are made in lieu of using a 
continuous opacity monitoring system, as allowed for by Sec. 60.273(c), 
visible emission observations shall be conducted at least once per day 
for at least three 6-minute periods when the furnace is operating in the 
melting and refining period. All visible emissions observations shall be 
conducted in accordance with Method 9. If visible emissions occur from 
more than one point, the opacity shall be recorded for any points where 
visible emissions are observed. Where it is possible to determine that a 
number of visible emission sites relate to only one incident of the 
visible emission, only one set of three 6-minute observations will be 
required. In that case, the Method 9 observations must be made for the 
site of highest opacity that directly relates to the cause (or location) 
of visible emissions observed during a single incident. Records shall be 
maintained of any 6-minute average that is in excess of the emission 
limit specified in Sec. 60.272(a).
    (j) Unless the presence of inclement weather makes concurrent 
testing infeasible, the owner or operator shall conduct concurrently the 
performance tests required under Sec. 60.8 to demonstrate compliance 
with Sec. 60.272(a) (1), (2), and (3) of this subpart.
