Rule Summary

New source performance standards (NSPS) for secondary brass and bronze ingot production plants were promulgated by the EPA on March 8, 1974 [39 FR 9309]. The secondary brass and bronze NSPS applies to reverberatory and electric furnaces of 1,000 kilogram (kg) [2,205 pound (lb)] or greater production capacity and blast (cupola) furnaces of 250 kilogram per hour (kg/h) [550 pound per hour (lb/h)] or greater production capacity, constructed or modified on or after June 11, 1973.

The standards regulate emissions of particulate matter collected during charging and refining phases and exhausted to the atmosphere through control devices. For reverberatory furnaces, the concentration' of particulate matter emissions in the exhaust gases must not exceed 50 milligrams per dry standard cubic meter (mg/dscm) [0.22 grains per dry standard cubic foot (gr/dscf)] and the opacity of visible emissions must not exceed 20 percent. For electric and blast (cupola) furnaces, the opacity of visible emissions must not exceed 10 percent.
