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* |
|---|---|---|---|
| 2022 |
Source Reduction:: S35: Other improvements to inventory and material management[-0-4%]
|
Methods to Identify SR Opportunities: T02: External pollution prevention opportunity audit(s)
Methods to Identify SR Opportunities: T11: Other |
S35: Monitor the stack gas for ammonia to ensure we are not using more ammonia than necessary. Source Reduction - Monitor the stack gas for ammonia to ensure we are not using more ammonia than necessary. Source Reduction - Took an opportunity to clean the SCR screens. |

S35: Regularly monitor the stack gas for ammonia to make sure we not using more ammonia than needed. Source Reduction - Regularly monitor the stack gas for ammonia to make sure we not using more ammonia than needed. Other Barriers to Source Reduction - Ammonia is used to minimize NOx stack emissions. We cannot eliminate its use, but we try to limit use to only what is needed. |

Source Reduction:: W19: Other changes in operating practices[-50-99%]
|
Methods to Identify SR Opportunities: T04: Participative team management
Methods to Identify SR Opportunities: T06: Employee recommendation (under a formal company program) Methods to Identify SR Opportunities: T11: Other |
W19: MOCs (management of changes) implementation along with operator training for good operating practices to optimize pollutants reactions by mean of SCR units. SCR and Ammonia injection grid system cleaning, thus increasing the catalysts performance and reducing ammonia usage |
| 2009 | Source Reduction - In 2009, the plant was shut down for 2 months. In addition, the ammonia is used for NOx emissions control. The DeNOx catalyst was changed out in the first half of 2009. After the catalyst was changed, daily ammonia stack measurements showed a significant decrease in the amount of ammonia being released through the stacks. The total ammonia released in 2009 reflects this. |
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")
