|---|---|---|---|
| 2022 |
Source Reduction:: S06: Other material modifications made[-25-49%]
|
Methods to Identify SR Opportunities: T03: Materials balance audits
Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies. |
S06: Implemented improved process control which improved bath life and reduced chemical purchases of Nitric Acid. Also instituted mini-bulk purchase and dispensing system to improve inventory maintenance and control. Source Reduction - Changed from purchase of material in 100 pound carboys to mini-bulk and on-site storage and dispensing from 500 gallon tank. Barriers to P2: B7 - No known substitutes or alternative technologies. - Processes utilizing Nitric Acid are specification driven and and not be modified. Modification of chemical control and inventory control have been successful to date. |
| 2021 |
Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.
|
Barriers to P2: B7 - No known substitutes or alternative technologies. - Per the applicable specification that the products manufactured at the facility, alternative chemical processes are not applicable. |
|
| 2020 |
Barriers: B8-Barriers to P2 B8 - A reduction does not appear to be technically feasible
|
Barriers to P2: B8 - A reduction does not appear to be technically feasible - The nitric acid utilized by the facility is in two major processing baths, for stripping silver from all of the part except the internal threads and for passivation to AMS2700. The specifications and customer requirements do not allow for substitutions and the level of use are proportional to the business activity. |
|
| 2019 |
Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.
|
Barriers to P2: B7 - No known substitutes or alternative technologies. - The nitric acid is used for two specific processes at the facility, passivation of stainless steels and super alloys and stripping silver and copper from unmasked areas of stainless steel and super alloy parts to meet customer and specification requirements. |
|
| 2017 |
Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.
|
Source Reduction: Source Reduction - Beginning in the third quarter of 2018, processing chemistry changes are planned for process stripping operations that will reduce the usage, treatment and disposal of Nitric Acid. Barriers to P2: B7 - No known substitutes or alternative technologies. - The chemical processes that utilize the Nitric Acid at Bristol Industries are controlled by industry standards and specifications for materials processing such as the passivization of stainless steels and high nickel alloys and the selective stripping of silver from similar materials from products sold to aircraft engine manufacturers. |

| 2015 |
Source Reduction:: W13: Improved maintenance scheduling, recordkeeping, or procedures[-0-4%]
Source Reduction:: W42: Substituted raw materials[-5-14%] |
Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
Methods to Identify SR Opportunities: T03: Materials balance audits Methods to Identify SR Opportunities: T10: Vendor assistance Methods to Identify SR Opportunities: T04: Participative team management Methods to Identify SR Opportunities: T09: Trade association/industry technical assistance program Methods to Identify SR Opportunities: T10: Vendor assistance |
W13: The Implementation of New ERP System on 1/2/2016 will provide additional inventory and ordering controls for RY 2016 and beyond. W42: Possible changes in contract requirements for passivation conducted per AMS2700 to change from nitric acid to Citric Acid based processes Source Reduction - Planned Engineering and Kaizen Events Source Reduction - Weekly Inventories of materials on hand provides better control of overall inventory turnover. Source Reduction - IFI Committee Assignment Source Reduction - Vendor stocks additional quantities of materials that are expected to be used and does provide better shelf life and treatment control. Source Reduction - Planned Engineering and Kaizen Events Other Environmental Practices: Source Reduction - Nitric Acid is used for the passivation of stainless steels and superalloys and for stripping silver and copper from pre-formed production parts. Source reduction will come from substitute stripping and passivation processes currently being explored at the facility. |

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")
