Pollution Prevention Activities for Selected Chemical
Reporting Year | Section 8.10: Newly Implemented Source Reduction Activity | Section 8.10: Methods to Identify Activity | Section 8.11: Optional Pollution Prevention Information* |
---|---|---|---|
2020 |
Barriers: B6-Barriers to P2 B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas
|
Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - Mechanical removal of coatings has reduced our dependence on nitric acid.Further reduction is not feasible at this time. |
|
2019 |
Source Reduction:: W59: Modified stripping/cleaning equipment[-0-4%]
|
Methods to Identify SR Opportunities: T11: Other
Methods to Identify SR Opportunities: T04: Participative team management |
W59: Increase grit blasting operations. Source Reduction - Coating building participants increased mechanical stripping Source Reduction - Mechanical stripping of parts |
2018 |
Barriers: B6-Barriers to P2 B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas
|
Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - Fume extraction was optimized to reduce evaporation of azeotropic nitric acid solution. |
|
2017 |
Barriers: B6-Barriers to P2 B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas
|
Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - Acid replenishment and acid recycle were both attempted and failed due to specific gravity changes to the product. |
|
2016 |
Source Reduction: Source Reduction - Efforts to upgrade our chemical scrubber equipment and reduce overall emissions have taken place during the latter part of 2016. Expectations are that source reduction will be achieved for the 2017 reporting year. |

2015 |
Source Reduction:: W14: Changed production schedule to minimize equipment and feedstock changeovers
|
Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program)
|
Source Reduction - Operators reduced the hours of idle bath heating which led to a small reduction in nitric acid use. |
2014 |
Source Reduction:: W50: Optimized reaction conditions or otherwise increased efficiency of synthesis
|
Methods to Identify SR Opportunities: T04: Participative team management
|
|
2013 |
Source Reduction:: W14: Changed production schedule to minimize equipment and feedstock changeovers
|
Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program)
|
W14: Nitric acid bath is used until exhausted. Source Reduction - Part cleanliness is used to determine when acid bath is no longer effective. |
2012 |
Source Reduction:: W60: Changed to mechanical stripping/cleaning devices (from solvents or other
|
Methods to Identify SR Opportunities: T04: Participative team management
|
|
2011 |
Source Reduction:: W60: Changed to mechanical stripping/cleaning devices (from solvents or other
|
Methods to Identify SR Opportunities: T04: Participative team management
|
Barriers to P2 - Our efforts to recover nitric acid were not successful. An option we are using this year is to gritblast parts that do not appear to need acid stripping. This reduces the need to strip the parts in acid, and reduces our acid use. |
2010 |
Source Reduction:: W60: Changed to mechanical stripping/cleaning devices (from solvents or other
|
Methods to Identify SR Opportunities: T04: Participative team management
|
Source Reduction - Grit blasting has been used in place of some of our acid stripping operations. Our customer satisfaction with this process will determine if if it will be used as a permanent change. Otherwise our acid use will increase with expected increase in production requirements. |
2009 |
Source Reduction:: W49: Other raw material modifications
|
Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
