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* |
|---|---|---|---|
| 2015 |
Other Environmental Practices: Source Reduction - Process improvements will decrease or eliminate the use of Dichloromethane in 2016.The material treated off-site has been updated based on typical effluent concentrations and actual flow rates. |

| 2013 |
Other Barriers to Source Reduction - We have developed a new process for manufacturing codeine phosphate without using methylene chloride. We are waiting for our customers to individually validate and file for the new material; since these are FDA regulated substances this process can take years. Once full commercialization of the new process is achieved, methylene chloride usage will go to zero. |
||
| 2009 | Other Environmental Practices - There was no accidental release in 2009 as it was the case in 2008 of methylene and this significantly explain the difference between the 2008 and 2009 onsite release of this chemical. The average concentration of this chemical in the waste streams sent offsite for energy use is from data that has a very wide range and this information was used to estimate the quantity that was sent to the POTW on a mass balance basis. This should explain why there are significant differences in the 2008 and 2009 quantities included in this report for onsite treatment and offsite energy recovery. | ||

Source Reduction:: W33: Installed overflow alarms or automatic shutoff valves
|
Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
|
|
| 2007 | Source Reduction - On my 29, 2007 an accidental incident occured at the site that resulted in the release of about 960 pounds of methylene chloride. The incident was reported to the appropriate authorities and coorective actions have been put in place to minmize the chance for a recurrence. |

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")
