Sec. 60.272  Standard for particulate matter.

    (a) On and after the date on which the performance test required to 
be conducted by Sec. 60.8 is completed, no owner or operator subject to 
the provisions of this subpart shall cause to be discharged into the 
atmosphere from an electric arc furnace any gases which:
    (1) Exit from a control device and contain particulate matter in 
excess of 12 mg/dscm (0.0052 gr/dscf).
    (2) Exit from a control device and exhibit three percent opacity or 
greater.
    (3) Exit from a shop and, due solely to operations of any EAF(s), 
exhibit 6 percent opacity or greater except:

[[Page 405]]

    (i) Shop opacity less than 20 percent may occur during charging 
periods.
    (ii) Shop opacity less than 40 percent may occur during tapping 
periods.
    (iii) The shop opacity standards under paragraph (a)(3) of this 
section shall apply only during periods when the monitoring parameter 
limits specified in Sec. 60.274(b) are being established according to 
Sec. 60.274(c) and (g), unless the owner or operator elects to perform 
daily shop opacity observations in lieu of furnace static pressure 
monitoring as provided for under Sec. 60.273(d).
    (iv) Where the capture system is operated such that the roof of the 
shop is closed during the charge and the tap, and emissions to the 
atmosphere are prevented until the roof is opened after completion of 
the charge or tap, the shop opacity standards under paragraph (a)(3) of 
this section shall apply when the roof is opened and shall continue to 
apply for the length of time defined by the charging and/or tapping 
periods.
    (b) On and after the date on which the performance test required to 
be conducted by Sec. 60.8 is completed, no owner or operator subject to 
the provisions of this subpart shall cause to be discharged into the 
atmosphere from dust-handling equipment any gases which exhibit 10 
percent opacity or greater.
