Commercial Enameling Company operates a grey iron foundry and enameling plant in Huntington Park, California. On February 11, 1976, a source test performed by the Los Angeles Air Pollution Control District (LAAPCD), determined that the cupola emissions contained 4,280 parts per million by volume (ppmv) carbon monoxide (CO), twice the allowable concentration (per LAAPCD Rule 71) of 2,000. LAAPCD cited the source for violating Rule 71 and required upgrading of the cupola. |
