The Reynolds Metals Plant Phoenix, Arizona, melts alloys and fluxes aluminum scrap which is then used to manufacture a variety of parts. One operation in the plant is the fluxing (degassing) of the molten aluminum before the metal is cast. The metal is fluxed by bubbling chlorine and nitrogen gas through the molten metal, during which the chlorine reacts with other gases and carries them out of the metal. on November 18, 1976, a pre-survey inspection (requested by EPA, Region IX) was conducted by NEIC at the Reynolds Metals Plant [Appendix A] to determine if EPA Method 5* sampling was feasible since fluxing is a batch operation of short duration. It was concluded from the pre-survey inspection that, if a sufficient number of ladles of aluminum were fluxed, the tests could be performed. |
