Source Reduction - Facility Flares and Cooling Towers equipped with Continuous Emissions Monitoring Systems(CEMS) in 2006. Data is provided from these systems. Flare and Cooling Tower emissions are calculated based on Texas Commission on Environmental Quality regulation 30 TAC Chapter 115, Subchapter H. The use of the CEMS system has resulted in some increase in ethylene and propylene emissions due to a reduction in flare efficiency and addition of cooling tower emissions. |

Source Reduction - Site implemented LDAR monitoing program of non-typical componets on an annual basis in 2005. Reporting of Fugitive Emissions inTRI for 2004 did not include increased monitoring and estimated emissions for RY 2004 were significantly higher due to state required estimation methodology for the non-monitored components. |

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")
