Sec. 60.275a  Test methods and procedures.

    (a) During performance tests required in Sec. 60.8, the owner or 
operator shall not add gaseous diluents to the effluent gas stream after 
the fabric in any pressurized fabric filter collector, unless the amount 
of dilution is separately determined and considered in the determination 
of emissions.
    (b) When emissions from any EAF(s) or AOD vessel(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. 60.276a(e)):
    (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 emission from any EAF(s) or AOD vessel(s) are combined with 
emissions from facilities not subject to the provisions of this subpart, 
the owner or operator shall demonstrate compliance with Sec. 
60.272(a)(3) based on emissions from only the affected facility(ies).
    (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. 60.272a 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 particulate matter 
concentration and volumetric flow rate of the effluent gas. The sampling 
time and sample volume for each run shall be at least 4 hours and 4.50

[[Page 417]]

dscm (160 dscf) and, when a single EAF or AOD vessel 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. 60.272a(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. 60.274a (c), (f), (g), and (h), the owner 
or operator shall obtain the information required in these paragraphs 
during the particulate matter runs.
    (g) Any control device subject to the provisions of the subpart 
shall be designed and constructed to allow measurement of emissions 
using applicable test methods and procedures.
    (h) Where emissions from any EAF(s) or AOD vessel(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 that 
compensates for the emissions from the facilities not subject to the 
provisions of this subpart, or;
    (3) Any combination of the criteria of paragraphs (h)(1) and (h)(2) 
of this section.
    (i) Where emissions from any EAF(s) or AOD vessel(s) are combined 
with emissions from facilities not subject to the provisions of this 
subpart, determinations of compliance with Sec. 60.272a(a)(3) will only 
be based upon emissions originating from the affected facility(ies).
    (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. 60.272a(a) (1), (2), and (3) of this subpart.
