# §60.372. Standards for lead.

- (a) On and after the date on which the performance test required to be conducted by [§ 60.8](/cfr/40/60.8.md) is completed, no owner or operator subject to the provisions of this subpart shall cause to be discharged into the atmosphere:
  - (1) From any grid casting facility any gases that contain lead in excess of 0.40 milligram of lead per dry standard cubic meter of exhaust (0.000175 gr/dscf).
  - (2) From any paste mixing facility any gases that contain in excess of 1.00 milligram of lead per dry standard cubic meter of exhaust (0.000437 gr/dscf).
  - (3) From any three-process operation facility any gases that contain in excess of 1.00 milligram of lead per dry standard cubic meter of exhaust (0.000437 gr/dscf).
  - (4) From any lead oxide manufacturing facility any gases that contain in excess of 5.0 milligrams of lead per kilogram of lead feed (0.010 lb/ton).
