(1) Iron, copper, and aluminum, andtheir alloys; and

(2) The nonferrous metals and theiralloys described in paragraph (a) of thissection. This part does not regulate theproduction of metal powders by chemi-cal means such as precipitation. Theproduction of metal powder as the finalstep in refining metal is regulatedunder the Nonferrous Metals Manufac-turing Point Source Category regula-tion, 40 CFR part 421.

(c) Surface treatment includes anychemical or electrochemical treatmentapplied to the surface of the metal. Forthe purposes of this regulation, surfacetreatment of metals is considered to bean integral part of the forming of met-als whenever it is performed at thesame plant site at which the metals areformed. Such surface treatment oper-ations are not regulated under theElectroplating or Metal FinishingPoint Source Category regulations, 40CFR part 413 or 433, respectively.

(d) Casting is covered by this partwhen it is performed as an integralpart of the metal forming process andtakes place at the same plant site atwhich metals are formed. Such castingwill not be regulated under the provi-sions of Metal Molding and CastingPoint Source Category regulations, 40CFR part 464.

(e) This part does not apply to theforming of the metals cadmium, chro-mium, gallium, germanium, indium,lithium, manganese, neodymium, orpraseodymium.

(3) The demonstration required underparagraph (d)(2) of this section shall bemade once per month until the dem-onstration has been made for all threenitrosamine compounds for six con-secutive months, after which time thedemonstration may be made once perquarter. If a sample is found to containany of the foregoing nitrosamine com-pounds at concentrations greater thanthose specified in paragraph (d)(2) ofthis section, the actions described inparagraph (d)(4) of this section shall betaken, and the demonstration requiredunder paragraph (d)(2) of this sectionshall be made once per month until ithas been made for all three nitrosa-mine compounds for six consecutivemonths.

(4) If sampling results show that anyof the foregoing nitrosamine com-pounds is present in the process waste-water at concentrations greater thanthose specified in paragraph (d)(2) ofthis section, the facility owner or oper-

ator shall ensure that, within thirtydays of receiving written notificationof the sampling results, there is no fur-ther discharge of tube reducing spentlubricant wastewater until the owneror operator:

(i) Performs a subsequent analysiswhich demonstrates that the con-centrations of the foregoing nitrosa-mine compounds do not exceed the lev-els specified in paragraph (d)(2) of thissection; or

(ii) Substitutes a new tube reducinglubricant and thereafter complies withthe requirements of paragraph (d)(3) ofthis section; or

(iii) Determines the source of the pol-lutant whose concentration exceededthe level specified in paragraph (d)(2) ofthis section and demonstrates to thesatisfaction of the NPDES issuing au-thority that such source has beeneliminated.

(5) The concentration limits specifiedin paragraph (d)(2) of this section applyat the point of discharge from the tubereducing process. However, samplingafter the tube reducing wastewater hasbeen commingled with otherwastewaters is permitted if:

(i) Any dilution caused by the otherwastewaters is taken into account indetermining the appropriate (i.e.,lower) allowable discharge concentra-tion; and

(ii) An analytical method of suffi-cient sensitivity is used to measure thelevels of each of the foregoing nitrosa-mine compounds in the wastewatersbeing sampled.

Aluminum alloys aredefined as any alloy in which alu-minum is the major constituent in per-cent by weight. Copper alloys are de-fined as any alloy in which copper isthe major constituent in percent byweight except when copper is alloyedwith precious metals. Any copper-pre-cious metal alloy containing 30 percentor greater precious metal is considereda precious metal alloy for the purposesof this part. Beryllium alloys are anyalloy in which beryllium is present at0.1 percent or greater. This part appliesto:

(1) Forming operations, includingrolling (both hot and cold), extruding,


605


forging, drawing, swaging, cladding,and tube reducing, and

(2) Ancillary operations performed asan integral part of the forming of thesemetals, including casting for subse-quent forming, heat treatment, surfacetreatment, alkaline cleaning, solventdegreasing, product testing, surfacecoating, sawing, grinding, tumbling,burnishing, and wet air pollution con-trol.

(b) This part also applies to dis-charges of pollutants to waters of theUnited States and introduction of pol-lutants into a publicly owned treat-ment works from mechanical metalpowder production operations, formingof parts from metal powders, and asso-ciated ancillary operations (listed inparagraph (a)(2) of this section) of:

(1) Iron, copper, and aluminum, andtheir alloys; and

(2) The nonferrous metals and theiralloys described in paragraph (a) of thissection. This part does not regulate theproduction of metal powders by chemi-cal means such as precipitation. Theproduction of metal powder as the finalstep in refining metal is regulatedunder the Nonferrous Metals Manufac-turing Point Source Category regula-tion, 40 CFR part 421.

(c) Surface treatment includes anychemical or electrochemical treatmentapplied to the surface of the metal. Forthe purposes of this regulation, surfacetreatment of metals is considered to bean integral part of the forming of met-als whenever it is performed at thesame plant site at which the metals areformed. Such surface treatment oper-ations are not regulated under theElectroplating or Metal FinishingPoint Source Category regulations, 40CFR part 413 or 433, respectively.

(d) Casting is covered by this partwhen it is performed as an integralpart of the metal forming process andtakes place at the same plant site atwhich metals are formed. Such castingwill not be regulated under the provi-sions of Metal Molding and CastingPoint Source Category regulations, 40CFR part 464.

(e) This part does not apply to theforming of the metals cadmium, chro-mium, gallium, germanium, indium,lithium, manganese, neodymium, orpraseodymium.

§ 471.02 General definitions.

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

(b) ‘‘Forming’’ is a set of manufactur-ing operations in which metals and al-loys are made into semifinished prod-ucts by hot or cold working.

(c) ‘‘Alkaline cleaning’’ uses a solu-tion (bath), usually detergent, to re-move lard, oil, and other such com-pounds from a metal surface. Alkalinecleaning is usually followed by a waterrinse. The rinse may consist of singleor multiple stage rinsing. For the pur-poses of this part, an alkaline cleaningoperation is defined as a bath followedby a rinse, regardless of the number ofrinse stages. Each alkaline cleaningbath and rinse combination is entitledto a discharge allowance.

(d) ‘‘Atomization’’ is the process inwhich a stream of water or gas im-pinges upon a molten metal stream,breaking it into droplets which solidifyas powder particles.

(i) ‘‘Continuous casting’’ is the pro-duction of sheet, rod, or other longshapes by solidifying the metal while itis being poured through an open-endedmold.

(j) ‘‘Degreasing’’ is the removal ofoils and greases from the surface of themetal workpiece. This process can be


606

40 CFR Ch. I (7–1–98 Edition)§ 471.02

accomplished with detergents as in al-kaline cleaning or by the use of sol-vents.

(k) ‘‘Direct chill casting’’ is the pour-ing of molten nonferrous metal into awater-cooled mold. Contact coolingwater is sprayed onto the metal as it isdropped into the mold, and the metalingot falls into a water bath at the endof the casting process.

(l) ‘‘Drawing’’ is the process of pull-ing a metal through a die or successionof dies to reduce the metal’s diameteror alter its cross-sectional shape.

(m) ‘‘Dye penetrant testing’’ is a non-destructive method for finding dis-continuities that are open to the sur-face of the metal. A dye is applied tothe surface of metal and the excess isrinsed off. Dye that penetrates surfacediscontinuities will not be rinsed awaythus marking these discontinuities.

(n) ‘‘Emulsions’’ are stable disper-sions of two immiscible liquids. In theNonferrous Metals Forming and MetalPowders Point Source category, this isusually an oil and water mixture.

(o) ‘‘Electrocoating’’ is theelectrodeposition of a metallic or non-metallic coating onto the surface of aworkpiece.

(p) ‘‘Extrusion’’ is the application ofpressure to a billet of metal, forcingthe metal to flow through a die orifice.

(q) ‘‘Forging’’ is deforming metal,usually hot, with compressive forceinto desired shapes, with or withoutdies. Where dies are used, the metal isforced to take the shape of the die.

(r) ‘‘Grinding’’ is the process of re-moving stock from a workpiece by theuse of a tool consisting of abrasivegrains held by a rigid or semi-rigidgrinder. Grinding includes surface fin-ishing, sanding, and slicing.

(s) ‘‘Heat treatment’’ is the applica-tion of heat of specified temperatureand duration to change the physicalproperties of the metal.

(t) ‘‘Hot pressing’’ is forming a pow-der metallurgy compact at a tempera-ture high enough to effect concurrentsintering.

(u) ‘‘Hydrotesting’’ is the testing ofpiping or tubing by filling with waterand pressurizing to test for integrity.

(v) ‘‘Impregnation’’ is the process offilling pores of a formed powder part,usually with a liquid such as a lubri-

cant, or mixing particles of a non-metallic substance in a matrix ofmetal powder.

(w) ‘‘In-process control technology’’is the conservation of chemicals andwater throughout the production oper-ations to reduce the amount of waste-water to be discharged.

(x) ‘‘Metal powder production’’ oper-ations are mechanical process oper-ations which convert metal to a finelydivided form.

(y) ‘‘Milling’’ is the mechanicaltreatment of a nonferrous metal toproduce powder, or to coat one compo-nent of a powder mixture with another.

(z) ‘‘Neat oil’’ is a pure oil with no orfew impurities added. In nonferrousmetals forming, its use is mostly as alubricant.

(aa) ‘‘Powder forming’’ includesforming and compressing powder into afully dense finished shape, and is usu-ally done within closed dies.

(bb) ‘‘Precious metals’’ include gold,platinum, palladium, and silver andtheir alloys. Any alloy containing 30 orgreater percent by weight of preciousmetals is considered a precious metalalloy.

(cc) ‘‘Product testing’’ includes oper-ations such as dye penetrant testing,hydrotesting, and ultrasonic testing.

(dd) ‘‘Refractory metals’’ includesthe metals of columbium, tantalum,molybdenum, rhenium, tungsten andvanadium and their alloys.

(ee) ‘‘Rolling’’ is the reduction inthickness or diameter of a workpieceby passing it between lubricated steelrollers.

(ff) ‘‘Roll bonding’’ is the process bywhich a permanent bond is created be-tween two metals by rolling under highpressure in a bonding mill (co-rolling).

(gg) ‘‘Sawing’’ is cutting a workpiecewith a band, blade, or circular disc hav-ing teeth.

(hh) ‘‘Shot casting’’ is the productionof shot by pouring molten metal infinely divided streams to form spheri-cal particles.

(ii) ‘‘Stationary casting’’ is the pour-ing of molten metal into molds and al-lowing the metal to cool.

(jj) ‘‘Surface treatment’’ is a chemi-cal or electrochemical treatment ap-plied to the surface of a metal. Suchtreatments include pickling, etching,


607


conversion coating, phosphating, andchromating. Surface treatment bathsare usually followed by a water rinse.The rinse may consist of single or mul-tiple stage rinsing. For the purposes ofthis part, a surface treatment oper-ation is defined as a bath followed by arinse, regardless of the number ofstages. Each surface treatment bath,rinse combination is entitled to dis-charge allowance.

(kk) ‘‘Swaging’’ is a process in whicha solid point is formed at the end of atube, rod, or bar by the repeated blowsof one or more pairs of opposing dies.

(ll) ‘‘Tube reducing’’ is an operationwhich reduces the diameter and wallthickness of tubing with a mandrel anda pair of rolls with tapered grooves.

(mm) ‘‘Tumbling’’ or ‘‘barrel finish-ing’’ is an operation in which castings,forgings, or parts pressed from metalpowder are rotated in a barrel with ce-ramic or metal slugs or abrasives to re-move scale, fins, or burrs. It may bedone dry or with an aqueous solution.
