Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
Methods to Identify SR Opportunities: T06: Employee recommendation (under a formal company program) Methods to Identify SR Opportunities: T04: Participative team management |
W52: Replaced 5,300 gallon bulk hazardous waste storage tank with a new, 14,000 gallon tank. The gasket/seal at the rupture disk on the emergency vent system of the old tank was sometimes leaking after a waste offload. The leak rate was monitored after waste offloads, and the rupture disk was being replaced, as needed. The new hazardous waste bulk storage tank has resulted in a reduction of fugitive emissions. Other Environmental Practices: General Environmental Management - Waste system components and bulk hazardous waste tank are monitored monthly for leaks using a flame ionization detector (FID). Chemical/process system components and bulk ACN tank are monitored quarterly for leaks using the FID. Incident investigations are conducted for all spills/releases involving chemicals to decrease the potential for a reoccurrence. Inspections of the bulk hazardous waste system and bulk ACN system are conducted daily. RCRA satellite accumulation areas and 90-day accumulation areas are inspected weekly. Identified leaks are repaired. Other Environmental Practices: Energy Recovery - Bulk organic hazardous waste, solid hazardous waste, and drummed organic waste is sent off-site for energy recovery. |

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")
