Sec. 60.142  Standard for particulate matter.

    (a) Except as provided under paragraph (b) of this section, 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 discharge or cause the discharge into the 
atmosphere from any affected facility any gases which:
    (1) Contain particulate matter in excess of 50 mg/dscm (0.022 gr/
dscf).

[[Page 372]]

    (2) Exit from a control device and exhibit 10 percent opacity or 
greater, except that an opacity of greater than 10 percent but less than 
20 percent may occur once per steel production cycle.
    (b) For affected facilities constructed, modified, or reconstructed 
after January 20, 1983, the following limits shall apply:
    (1) On or after the date on which the performance test under Sec. 
60.8 is required to be completed, no owner or operator of an affected 
facility for which open hooding is the method for controlling primary 
emissions shall cause to be discharged to the atmosphere any gases that:
    (i) Contain particulate matter in excess of 50 mg/dscm (0.022 gr/
dscf), as measured for the primary oxygen blow.
    (ii) Exit from a control device not used solely for the collection 
of secondary emissions, as defined in Sec. 60.141a, and exhibit 10 
percent opacity or greater, except that an opacity greater than 10 
percent but less than 20 percent may occur once per steel production 
cycle.
    (2) On or after the date on which the performance test required by 
Sec. 60.8 is completed, no owner or operator of an affected facility 
for which closed hooding is the method for controlling primary emissions 
shall cause to be discharged into the atmosphere any gases that:
    (i) Contain particulate matter in excess of 68 mg/dscm (0.030 gr/
dscf), as measured for the primary oxygen blow.
    (ii) Exit from a control device not used solely for the collection 
of secondary emissions, as defined in Sec. 60.141a, and exhibit 10 
percent opacity or greater, except that an opacity greater than 10 
percent but less than 20 percent may occur once per steel production 
cycle.
    (c) On and after the date on which the performance test required by 
Sec. 60.8 is completed, each owner or operator of an affected facility 
subject to paragraph (b) of this section shall operate the primary gas 
cleaning system during any reblow in a manner identical to operation 
during the primary oxygen blow.
