§ 467.50 Applicability; description of the drawing with neat oils subcategory.
top
This subpart applies to discharges of pollutants to waters of the United States and introductions of pollutants into publicly owned treatment works from the core of the drawing with neat oils subcategory and the ancillary operations.
§ 467.51 Specialized definitions.
top
For the purpose of this subpart:
(a) The “core” of the drawing with neat oils subcategory shall include drawing using neat oils, stationary casting, artificial aging, annealing, degreasing, sawing, and swaging.
(b) The term “ancillary operation” shall mean any operation not previously included in the core, performed on-site, following or preceding the drawing operation. The ancillary operation shall include continuous rod casting, solution heat treatment, and cleaning or etching.
§ 467.52 Effluent limitations representing the degree of effluent reduction attainable by the application of best practicable control technology currently available.
