| 2018 |
Barriers to P2 - N-Hexane is a component of natural gasoline which is used as a federally mandated denaturant into fuel ethanol
Other Barriers to Source Reduction - Denaturing of fuel grade ethanol is a Federal government mandated activity. |

Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.
|
Barriers to P2: B7 - No known substitutes or alternative technologies. - N-Hexane is a component of natural gasoline which is used as a federally mandated denaturant into fuel ethanol |

| 2016 |
Source Reduction:: W32: Improved procedures for loading, unloading, and transfer operations[-0-4%]
|
Methods to Identify SR Opportunities: T02: External pollution prevention opportunity audit(s)
|
|
| 2015 |
Source Reduction:: W50: Optimized reaction conditions or otherwise increased efficiency of synthesis[-0-4%]
|
Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program)
|
Source Reduction - Better energy efficiency will lead to less natural gas and hence, less n-Hexane that is used to fuel the process. |
| 2014 |
Barriers: B5-Barriers to P2 B5 - Specific regulatory/permit burdens.
|
Barriers to P2: B5 - Specific regulatory/permit burdens. - N-Hexane is a component of natural gasoline used in the government mandated denaturing of ethanol. |

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")
