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*
2021		Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.	Barriers to P2: B7 - No known substitutes or alternative technologies. - FDA Approved Formula
2020		Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.	Barriers to P2: B7 - No known substitutes or alternative technologies. - FDA approved process for manufacturing medication
2019		Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.	Barriers to P2: B7 - No known substitutes or alternative technologies. - Material is ingredient in FDA approved pharmaceutical manufacturing process
2018		Barriers: B6-No Information B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas	Other Environmental Practices: Recycling - Due to EPA changes related to allowable use of Methylene Chloride in 2019, it is no longer economically viable to recycle the waste solution generated from this process. Therefore, estimates for recycled waste in 2019 reflect only a few months of recycling and incineration for the remaining portion of the year. Further, it is expected that all waste generated in 2020 will have to be sent for incineration.
2017		Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.	Barriers to P2: B7 - No known substitutes or alternative technologies. - FDA approved manufacturing process
2016		Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.	Barriers to P2: B7 - No known substitutes or alternative technologies. - FDA regulated process.
2015		Barriers: B4-Barriers to P2 B4 - Source reduction activities were implemented but were unsuccessful.	Barriers to P2: B4 - Source reduction activities were implemented but were unsuccessful. - Material use dictacted by FDA approved formula for product manufacturing process.
2014		Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.	Source Reduction: General Environmental Management - Procedures for manufacturing process and waste management process minimize waste generated and reduce waste resulting from errors. Barriers to P2: B7 - No known substitutes or alternative technologies. - FDA regulated formula for production cannot be altered. Other Environmental Practices: Recycling - Waste solution remaining after production activities have been completed is sent for offsite recycling and reuse.
2013			Other Barriers to Source Reduction - No source reduction opportunities identified.
2006	Source Reduction:: W52: Modified equipment, layout, or piping	Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
2005	Source Reduction:: W32: Improved procedures for loading, unloading, and transfer operations Source Reduction:: W52: Modified equipment, layout, or piping	Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s) Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
1994	Source Reduction:: W19: Other changes in operating practices	Methods to Identify SR Opportunities: T04: Participative team management

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.

Source Reduction includes activities that eliminate or reduce the generation of chemical waste.
Recycling includes the recovery of a toxic chemical in waste for reuse.
Energy Recovery includes the combustion of toxic chemicals in waste to generate heat or electricity.
Treatment includes the destruction of a toxic chemical in waste.
Disposal or Other Releases includes toxic chemical quantities entering the environment.

The PPA requires facilities to provide the following details about each chemical they report to TRI:

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")

Facilities may also provide optional Pollution Prevention Information describing their source reduction, recycling, or pollution control activities.
