Barriers: B8-Barriers to P2 B8 - A reduction does not appear to be technically feasible
|
Other Environmental Practices: Waste Treatment - Our nitric acid and pickling rinse waters are treated in-house and neutralized prior to discharge to the sanitary sewer as per our sanitary authority Industrial Discharge Permit. All acid is neutralized and no longer detrimental to the environment. Other Environmental Practices: General Environmental Management - Our treated rinse waters are analyzed at least two times every year for compliance to our Industrial Discharge Permit through the sanitary authority. Barriers to P2: B8 - A reduction does not appear to be technically feasible - ASTM A967 does allow for citric acid passivation in place of nitric acid passivation, and we do suggest to our customers that they switch to citric acid passivation, but the decision is ultimately that of our customers. Also, ASTM B912 only allows for a post dip in nitric acid following electropolishing operations. |

Barriers: B8-Barriers to P2 B8 - A reduction does not appear to be technically feasible

Other Barriers to Source Reduction - ASTM A967 is specific about the concentrations of nitric acid for passivation of stainless steel. We adhere to the criteria for Nitric 2 which allows for a nitric acid concentration of 20-45%. This range also allows us to adhere to the post dip requirements in ASTM B912 for the passivation of stainless steels by electropolishing with 10-30% nitric acid. Other Environmental Practices: General Environmental Management - Our treated rinse waters are analyzed at least two times every year for compliance to our Industrial Discharge Permit through the sanitary authority. Barriers to P2: B8 - A reduction does not appear to be technically feasible - ASTM A967 does allow for citric acid passivation in place of nitric acid passivation, and we do suggest to our customers that they switch to citric acid passivation, but the decision is ultimately that of our customers. However, ASTM B912 only allows for a post dip in nitric acid following electropolishing. Other Environmental Practices: Waste Treatment - Our nitric acid rinse waters are treated in-house and neutralized prior to discharge to the sanitary sewer as per our sanitary authority Industrial Discharge Permit. All acid is neutralized and no longer detrimental to the environment. |

Other Barriers to Source Reduction - Increasing the purity of concentration of the nitric acid we purchase may create regulatory issues with the Department of Homeland Security. Concentrated nitric acid is a chemical of interest under CFATS (Chemical Facility Anti-Terrorism Standards). Source Reduction: Source Reduction - ASTM A967 also allows for citric acid passivation of stainless steel. We do strongly suggest to our customers that they switch to citric acid, but the decision is ultimately theirs. Barriers to P2: B7 - No known substitutes or alternative technologies. - ASTM A967 for the passivation of stainless steel requires the use of nitric acid. Many customers require nitric passivation. Other Environmental Practices: General Environmental Management - Our nitric acid rinse waters are treated in-house and neutralized prior to discharge to the sewer as per our sanitary authority permit. All acid is neutralized and no longer detrimental to the environment. Other Environmental Practices: Waste Treatment - Our nitric acid rinse waters are treated in-house and neutralized prior to discharge to the sewer as per our sanitary authority permit.

Concentrated nitric acid is a chemical of interest under CFATS (Chemical Facility Anti-Terrorism Standards). Barriers to P2: B7 - No known substitutes or alternative technologies. - ASTM A967 for the passivation of stainless steel requires the use of nitric acid. Many customers specifically request nitric acid passivation. Source Reduction: Source Reduction - ASTM A967 also allows for citric acid passivation of stainless steel. We do strongly suggest to our customers that they switch to citric acid, but the decision is solely theirs. Other Environmental Practices: General Environmental Management - Our nitric acid rinse waters are treated in-house and neutralized prior to discharge to the sewer as per our sanitary authority permit. 100% of the acid is neutralized and no longer detrimental to the environment.

W42: We urge customers to switch from nitric acid passivation to citric acid passivation. We also use more dilute nitric acid solutions after our electropolishing processing. Source Reduction - We have both nitric acid passivation and citric acid passivation in dedicated process tanks. The volumes remain constant throughout the year. Barriers to P2: B8 - A reduction does not appear to be technically feasible - Some customers insist on nitric acid passivation. Barriers to P2: B7 - No known substitutes or alternative technologies. - This facility performs electropolishing and nitric acid passivation. ASTM B912 for electropolishing requires a post electropolishing nitric acid dip. As production for electropolishing and for nitric acid passivation increases, so too will the use of nitric acid. |

Other Environmental Practices: Waste Treatment - All nitric acid rinses are effectively neutralized to pH 5-9 in our 3-step wastewater treatment process. Barriers to P2: B7 - No known substitutes or alternative technologies. - This facility performs electropolishing and nitric passivation. ASTM B912 for electropolishing requires a post electropolishing nitric acid dip. As production for electropolishing and for nitric passivation increases, so too will the use of nitric acid. |

Other Environmental Practices: Waste Treatment - Nitric acid rinse waters are effectively neutralized through wastewater treatment. Barriers to P2: B7 - No known substitutes or alternative technologies. - Passivation procedures for stainless steel require the use of nitric acid. As demands for passivation increase, so too will the use of nitric acid. Other Environmental Practices: General Environmental Management - Our treated wastewaters meet or exceed the parameters set forth in our discharge permit regulated by the Bradford Sanitary Authority. Analyses are performed by an independent laboratory. |

Barriers: B7-No Information B7 - No known substitutes or alternative technologies.
|
Other Barriers to Source Reduction - As production increases, so too must nitric acid usage. Other Environmental Practices: Waste Treatment - Allegheny Surface Technology has its own state-of-the-art wastewater treatment process. The wastewater is comprised of the rinse water created after stainless steel pieces are dipped into a nitric acid bath to promote the growth of a chemically inert passive layer that helps prevent corrosion of the stainless. The pH of the rinse water is adjusted into the neutral range thereby destroying the corrosive nature of the residual acid. |

W24: We are compliant with the GHS labeling system and have specific procedures for proper labeling of unused materials, in-process materials and waste materials. W55: This raw material is delivered in reusable stainless steel totes. Source Reduction - We work closely with our vendors to ensure we create as little waste as possible. Source Reduction - Every employee is trained for safe work practices and is therefore also a member of participative team management. All employees are encouraged to make suggestions and help implement safer working conditions. Other Environmental Practices - We have recuperated from the fire of July 2012, and we built a state-of-the-art facility with safety and protection to the environment as our top priorities. Our process baths are reinforced. Process tanks are located within floor containment pits. The building itself is another barrier of containment. |
