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 |
Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.
|
Barriers to P2: B7 - No known substitutes or alternative technologies. - Chemical is a byproduct of specialized manufacturing process. |
|
| 2021 |
Source Reduction:: S21: Optimized process conditions to increase efficiency[-0-4%]
|
Methods to Identify SR Opportunities: T03: Materials balance audits
Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies. |
S21: Pipe cleaning lead to greater efficiency Source Reduction - Optimization push lead to looking at process mass balance which lead to a more regular PM to optimize flows. Barriers to P2: B7 - No known substitutes or alternative technologies. - Byproduct is a result of required raw materials |
| 2020 |
Other Environmental Practices: General Environmental Management - Site has initiated a project do reduce use of combustion gases which will drive down output of toxic chemicals. |

| 2019 |
Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.
|
Barriers to P2: B7 - No known substitutes or alternative technologies. - Natural Gas is used as a raw material in process |
|
| 2015 | Other Environmental Practices - An initiative was put in place in 2014 to reuse process waters in place of city water. The positive effects of this initiative are still being realized in 2015. | ||
| 2014 |
Barriers: B2-Barriers to P2 B2 - Require technical information on pollution prevention techniques applicable to specific production processes.
|
Other Environmental Practices: Energy Recovery - The site is currently able to reuse 99.9% of the ethylene produced in an industrial boiler. Barriers to P2: B2 - Require technical information on pollution prevention techniques applicable to specific production processes. - Carbon filters may be possible for emissions from pop off vents. Other technologies may be available as well. |

| 2012 |
Other Barriers to Source Reduction - Ethylene is a by-product fuel of the thermal breakdown of Propane in our manufacturing process. The Ethylene is not considered a waste gas, but instead a useful fuel source for our industrial boilers. Therefore, the facility does not plan to implement any source reduction activities concerning Ethylene. |

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")
