                  Institutional Steam Generating Units

 

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).

    (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.
