Barriers: B3-Barriers to P2 B3 - Concern that product quality may decline as a result of source reduction. Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies. |
Barriers to P2: B3 - Concern that product quality may decline as a result of source reduction. - KPW extends the life of its nitric acid baths as long as possible through frequent monitoring and additions.However, the more contaminated the nitric acid gets, the greater the decline in its cleaning and descalingabilities. Quality begins to suffer at a certain saturation point which then requires discarding the old solutionand making a new one. Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - KPW has process controls in place to extend and reduce the amount of nitric acid used in its processes. Nitricacid remains a vital chemistry in the pretreatment of certain materials. The amount of nitric acid used alsodepends on the amount and condition of material processed. These variables will cause the volume of nitricacid and its waste to fluctuate yearly. Barriers to P2: B7 - No known substitutes or alternative technologies. - Research and experimentation has been conducted to find alternatives to nitric acid. However, all otheralternatives proved to be less robust, difficult to control, cost prohibitive, and/or used other hazardousmaterials making them unacceptable as a production replacement. Other Environmental Practices: Waste Treatment - All nitric acid is eventually treated by Klein Plating in its wastewater treatment system before discharge to its local POTW. The treatment involves neutralizing the material to a pH above 6.0 thus effectively destroying it. However, the neutralization of nitric acid then creates nitrate compounds which triggers the reporting of that hazardous substance. |

Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - KPW has already implemented process controls to extend and reduce the amount of nitric acid used in its processes. These efforts were successful in the past, but nitric acid remains a vital chemistry in the pretreatment of certain materials. The amount of nitric acid used also depends on the amount and condition of material processed. These variables will cause the amount of nitric acid waste to fluctuate yearly. Barriers to P2: B7 - No known substitutes or alternative technologies. - Research and experimentation has been done to find alternatives to nitric acid. However, other options proved to be less robust, difficult to control, cost prohibitive, and used other hazardous materials making them unacceptable as a production replacement. Barriers to P2: B3 - Concern that product quality may decline as a result of source reduction. - KPW has implemented past programs that sought to extend the life of nitric acid pickle baths by means of frequent monitoring and additions. Extending the life would reduce the total volume used in a year. However, the more contaminated the nitric acid gets, the greater the decline in its cleaning and descaling abilities so quality begins to suffer at a certain saturation point. Other Environmental Practices: Waste Treatment - All nitric acid used at Klein Plating is eventually treated in its wastewater treatment system before discharge to the local POTW. The neutralization and treatment of this material effectively destroys it, but in doing so creates nitrate compounds which triggers the reporting of that hazardous substance. |

Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies. |
Barriers to P2: B7 - No known substitutes or alternative technologies. - Other methods of oxidizing and removing copper scale proved difficult to control, cost prohibitive, or created waste treatment issues such as sulfuric mixed with hydrogen peroxide. Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - KPW has implemented various new processes and controls in the past to reduce the use of nitric acid. These reduction efforts were successful but nitric acid remains a vital chemistry in pre-treating certain materials. Further reduction seems unlikely due to a lack of feasible/economical alternatives. Nitric usage also depends on the volume of work ran and the condition of the material treated. These variables will always cause a fluctuation in the amount used. Other Environmental Practices: Recycling - There is equipment that will purify spent nitric acid baths through diffusion dialysis. This may be a way of reducing nitric acid consumption. Further exploration is needed to see if it is a viable method. Other Environmental Practices: Waste Treatment - All the nitric acid used at Klein Plating is eventually treated in its wastewater treatment system before discharged to the local POTW. No nitric acid leaves the facility. The neutralization and treatment of this material creates nitrate compounds which triggers the reporting of that hazardous substance. |

W78: Klein Plating implemented new chemistries that reduced the amount if nitric used in its processes. Source Reduction: Source Reduction - Nitric acid is a vital chemistry in pre-treating certain metals prior to plating. Reduction efforts have been made but further reduction is unlikely due to a lack of feasible/economical alternatives. It's usage also depends on the volume of business which requires it and the condition of the material. The variables fluctuate which will in turn cause the amount of nitric acid usage to fluctuate. Other Environmental Practices: Waste Treatment - All the nitric acid used at Klein Plating is neutralized and treated in its in-house waste treatment system before discharge to the local POTW. No nitric acid leaves the facility. The waste treatment of it creates nitrate compounds which causes the reporting of that hazardous substance. |

W71: Klein Plating sought various chemical mixtures or formulas that would successfully pre-treat parts while using less nitric acid. Chemistries containing less nitric have shown effective and have been implemented. Other Environmental Practices: Waste Treatment - All of Klein Plating's spent nitric acid is neutralized and treated in its in-house waste treatment system before discharge to the local POTW. No nitric acid leaves the facility but the treatment of it generates nitrate compounds which triggers the reporting of that hazardous substance. Source Reduction: Source Reduction - Nitric acid is used as in pre-treatment methods for copper, copper alloys, and aluminum parts to remove heat scale, smuts and other metallic coatings prior to plating them. Alternative methods or milder pre-treatments have been researched and some implemented to reduce the use of this hazardous material. However, its usage is dependent on the amount of material processed and its incoming condition (such as the amount of heat scale that needs to be removed) so usage will fluctuate accordingly. Klein Plating has not discovered an alternative to its usage in certain applications and there is no known way to greatly eliminate or reduce it. |

Barriers to P2: Source Reduction - Nitric acid is used as a pre-treatment method on copper, copper alloy, and aluminum parts to remove heat scale and smuts as well as strip metallic coatings. Klein Plating was sought ways to reduce the usage of nitric acid and/or find an alternative method. However, the hazardous substance's usage is dependant on the amount of material processed and its incomig condition (i.e. amount of heat scale) so usage will fluctuate accordingly. Although Klein Plating has implemented a few new prcoessing methods to reduce the amount of nitric acid used, it has not discovered an alternative means to greatly reduce or eliminate it. Other Environmental Practices: Waste Treatment - All of Klein Plating's nitric acid is neutralized on site in its in-house waste treatment system before it is discharged to the local POTW. |

Other Environmental Practices - Nitric acid is used to pre-treat components with heat scale and surface smut. In many instances it is the only viable option to properly prepare some of the articles for plating. Klein Plating is actively investigating alternative processing methods to reduce its nitric usage. However, nitric acid will always be required due to the nature of the parts plated. Nitric acid usage will change with fluctuations in production.
Other Barriers to Source Reduction - Klein Plating switched chemistries in its pre-treatment of copper to help reduce the amount of copper metal removed during pre-treatment. This was successful and led to a decrease in copper releases, but it also resulted in an increase in nitric acid usage. Alternatives to reduce nitric acid consumption are currently being investigated. |

TRI Pollution Prevention Glossary
The Waste Management Hierarchy |
The waste management hierarchy established by the Pollution Prevention Act (PPA) guides waste generators toward the best options for managing wastes.
The preferred option is to prevent pollution at its source, but for waste that is generated, the preferred management methods are recycling, followed
by burning for energy recovery, treatment and, as a last resort, disposing of the waste.
|
- A breakdown of production-related waste managed. This includes all amounts of the chemical released directly to the environment or otherwise managed as waste, other than waste generated by one-time events not associated with normal production processes (e.g., fires or remedial actions).
- A production ratio or activity index to provide context for reported toxic chemical quantities. For example, if a chemical is used in the manufacture of refrigerators, the production index would track the number of refrigerators produced and could be used to help gauge how much of the chemical is being released per unit of production.
- Any newly implemented source reduction activities, reported using "W-codes" (e.g., "W41: Increased purity of raw materials")
