Development Document for Effluent Limitations Guidelines and Standards for the Nonferrous Metals Manufacturing Point Source Category, Volume II: Bauxite Refining, Primary Aluminum Smelting, Secondary Aluminum Smelting, Final.
On April 8, 1974, EPA promulgated effluent limitations based on best practicable technology currently available (BPT) and best available technology economically achievable (BAT), standards of performance for new sources (NSPS) and pretreatment standards for new sources (PSNS).
The bauxite refining subcategory consists of 8 plants. Of the 8 plants, three discharge directly to rivers, lakes, or streams and five achieve zero discharge of process wastewater.
