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:: S21: Optimized process conditions to increase efficiency[-0-4%]	Methods to Identify SR Opportunities: T04: Participative team management 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 site looks to reduce waste/carbon footprint. Production volumes have increased for this blended product. In addition, we have an engineering team to increase efficiency, therefore, reducing waste.
2021	Source Reduction:: S25: Other process modifications made[-0-4%]	Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s) Barriers: B8-Barriers to P2 B8 - A reduction does not appear to be technically feasible	S25: Our production of the product that involves this material will stay the same. We constantly use the material. If anything were to changes it would mean a decrease in emissions due to less use of the materials. Source Reduction - For this material we have a dedicated line filler. This has been implemented and reduces the amount of waste that we use to produce from changing over from product to product. Barriers to P2: B8 - A reduction does not appear to be technically feasible - Our site is always looking to reduce our waste/carbon footprint. We have a team dedicated to reducing waste in any form.
2020	Source Reduction:: W36: Implemented inspection or monitoring program of potential spill or leak sources[-15-24%]	Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s) Barriers: B8-Barriers to P2 B8 - A reduction does not appear to be technically feasible	W36: For this specific material we have dedicated lines and equipment. We also have containers under all connections to capture any possible leaks at connection points. Source Reduction - For this specific material we have dedicated lines and equipment. We also have containers under all connections to capture any possible leaks at connection points. Barriers to P2: B8 - A reduction does not appear to be technically feasible - For this specific material we have dedicated lines and equipment. We also have containers under all connections to capture any possible leaks at connection points.
2019		Barriers: B8-Barriers to P2 B8 - A reduction does not appear to be technically feasible	Other Environmental Practices: General Environmental Management - containers are set under all fittings when transferring any materials onsite. This is to catch any possible drips/leaks and is a practice for all materials on-site. Barriers to P2: B8 - A reduction does not appear to be technically feasible - The material already has dedicated lines, hoses, pumps and filters. This eliminates the production of waste.
2018		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 - Due to dedicated system, waste is minimized to sampling only.
2017	Source Reduction:: W19: Other changes in operating practices[-0-4%]	Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program)	W19: Filter life extension to minimize waste on change out. Source Reduction - Recommendation from employees using Accident Preventive Techniques system. Other Environmental Practices - Accident preventive techniques system that all employees participate in to help identify things like pollution prevention. Daily inspections of work areas to prevent pollution of the work areas due to leaks and possible spills. Other Environmental Practices: General Environmental Management - Procedures in place to promote pollution prevention. (Drip/catch pans, dedicated hoses/systems)
2016	Source Reduction:: W32: Improved procedures for loading, unloading, and transfer operations	Methods to Identify SR Opportunities: T04: Participative team management	W32: Dedicated lines, drums, filter housing for the material. Less waste/flush. Source Reduction - Management team decision to dedicate equipment to limit waste/flush. Other Environmental Practices: Recycling - Working with waste vendors to try and find alternative outlets for the waste/flush material that we are still generating.
2015	Source Reduction:: W32: Improved procedures for loading, unloading, and transfer operations	Methods to Identify SR Opportunities: T11: Other	W32: Made dedicated equipment. Specifically tankwagon unloading hoses. Eliminates washing/rinsing out hoses of previous products. Other Environmental Practices: Recycling - Currently working with a nonprofit outside group to help with our waste program. To continually try and reduce our chemical waste and landfill waste as well.
2013			Other Environmental Practices - We have implemented a recycle program that doesn't fall into any of the categories listed. Our materials for disposal are a substitute for a commercially available product.
2012	Source Reduction:: W29: Other changes in inventory control	Methods to Identify SR Opportunities: T06: Employee recommendation (under a formal company program)	W29: identified a user for the waste that can use the waste as an effective substitute for a commercially available product.

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.
