| 2005 | Other Environmental Practices - Manganese is one of the components of the fly ash and bed ash produced as by-products of the power production. In 2005 100% of the fly and bed ash produced (as a by-product) were directly reused or marketed/sold (commerce) for beneficial use replacing other commercial products (e.g.cement) or used as raw material in the on-site aggregate manufacturing process for beneficial applications. The 100% of the aggregate (final product- A-2 and A-2-4 Class) produced in 2005 was sold for different clients for aggregate construction applications substituing natural aggregates, maximizing the use of the natural resources (limestone, coal), reducing the environmental impact and erosion/sedimentation of water bodies due to the natural resources extractions activities and saving landfill space. The manufactured aggregate physical, mechanical and chemical characteristics comply with the engineering standards for the A-2 or A-2-4 aggregate construction applications (clients applications). |

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")
