GENERAL PROVISIONS

§ 467.01 Applicability.

(a) Aluminum forming includes com-monly recognized forming operationssuch as rolling, drawing, extruding,and forging and related operations suchas heat treatment, casting, and surfacetreatments. Surface treatment of alu-minum is any chemical or electro-chemical treatment applied to the sur-face of aluminum. Such surface treat-ment is considered to be a part of alu-minum forming whenever it is per-formed as an integral part of aluminumforming. For the purposes of this regu-lation, surface treatment of aluminumis considered to be an integral part ofaluminum forming whenever it is per-formed at the same plant site at whichaluminum is formed and such oper-ations are not considered for regula-tion under the Electroplating andMetal Finishing provisions of 40 CFRparts 413 and 433. Casting aluminumwhen performed as an integral part ofaluminum forming and located on-siteat an aluminum forming plant is con-sidered an aluminum forming oper-ation and is covered under these guide-lines. When aluminum forming is per-formed on the same site as primaryaluminum reduction the casting shallbe regulated by the nonferrous metalsguidelines if there is no cooling of thealuminum prior to casting. If the alu-minum is cooled prior to casting thenthe casting shall be regulated by thealuminum forming guidelines.

(b) This part applies to any alu-minum forming facility, except forplants identified under paragraph (c) ofthis section, which discharges or maydischarge pollutants to waters of theUnited States or which introduces ormay introduce pollutants into a pub-licly owned treatment works.

(c) This part is applicable to indirectdischarging aluminum forming plantsthat extrude less than 3 million poundsof product per year and draw, withemulsions or soaps, less than 1 millionpounds per year.

NOTE: This paragraph is promulgated as anInterim Final Rule.

§ 467.02 General definitions.

In addition to the definitions setforth in 40 CFR part 401, the followingdefinitions apply to this part:

(a) Aluminum forming is a set of man-ufacturing operations in which alu-minum and aluminum alloys are madeinto semifinished products by hot orcold working.

(b) Ancillary operation is a manufac-turing operation that has a large flow,discharges significant amounts of pol-lutants, and may not be present atevery plant in a subcategory, but whenpresent is an integral part of the alu-minum forming process.

(c) Contact cooling water is any waste-water which contacts the aluminumworkpiece or the raw materials used informing aluminum.

(d) Continuous casting is the produc-tion of sheet, rod, or other long shapesby solidifying the metal while it isbeing poured through an open-endedmold using little or no contact coolingwater. Continuous casting of rod andsheet generates spent lubricants androd casting also generates contactcooling water.

(e) Degassing is the removal of dis-solved hydrogen from the molten alu-minum prior to casting. Chemicals areadded and gases are bubbled throughthe molten aluminum. Sometimes awet scrubber is used to remove excesschlorine gas.

(f) Direct chill casting is the pouring ofmolten aluminum into a water-cooledmold. Contact cooling water is sprayedonto the aluminum as it is droppedinto the mold, and the aluminum ingotfalls into a water bath at the end of thecasting process.

(g) Drawing is the process of pullingmetal through a die or succession ofdies to reduce the metal’s diameter oralter its shape. There are two alu-minum forming subcategories based onthe drawing process. In the drawingwith neat oils subcategory, the draw-ing process uses a pure or neat oil as a

(y) PSNS means pretreatment stand-ards for new sources, under section307(c) of the Act.

(z) The production normalizing mass(/kkg) for each core or ancillary oper-ation is the mass (off-kkg or off-lb)processed through that operation.

(aa) The term off-kilogram (off-pound)shall mean the mass of aluminum oraluminum alloy removed from a form-ing or ancillary operation at the end ofa process cycle for transfer to a dif-ferent machine or process.

§ 467.03 Monitoring and reporting re-quirements.

The following special monitoring andreporting requirements apply to all fa-cilities controlled by this regulation.

(a) Periodic analyses for cyanide asmay be required under part 122 or 403 ofthis chapter are not required whenboth of the following conditions aremet:

(1) The first wastewater sample ofeach calender year has been analyzedand found to contain less than 0.07 mg/l cyanide.

(2) The owner or operator of the alu-minum forming plant certifies in writ-ing to the POTW authority or permitissuing authority that cyanide is notand will not be used in the aluminumforming process.

(b) As an alternative monitoring pro-cedure for pretreatment, the POTWuser may measure and limit oil andgrease to the levels shown inpretreatment standards in lieu ofmeasuring and regulating total toxicorganics (TTO).

(c) The ‘‘monthly average’’ regu-latory values shall be the basis for themonthly average discharge limits in di-rect discharge permits and forpretreatment standards. Compliancewith the monthly discharge limit is re-

quired regardless of the number of sam-ples analyzed and averaged.

(Information collection requirements inparagraph (a) were approved by the Office ofManagement and Budget under control num-ber 2040–0033)

Removal allowances pursuant to 40CFR 403.7(a) may be granted for thetoxic metals limited in 40 CFR part 467when used as indicator pollutants.
