Under the Pollution Prevention Act of 1990 (PPA), TRI collects information to track industry progress in reducing waste generation and moving towards safer waste management alternatives. Measures that facilities have taken to prevent pollution and reduce the amount of toxic chemicals entering the environment are shown in the table below. Although factors other than these reported practices contribute to year-to-year changes in releases, results are sorted by largest reduction in order to facilitate identification of pollution prevention successes. View the to learn about this report's features.

Hydrochloric Acid (1995 And After "Acid Aerosols" Only) 221112: Fossil Fuel Electric Power Generation 2005 47,141.00 18,928.00 -59.85% Hydrochloric acid (in flue gas) from the fuel combustion process is neutralized with water, limestone and hydrated lime , additionally with a Circulating Dry Scrubber. The facility continously evaluate the fuel chlorine concentration to define the projected nuetralization chemicals target injection for tracking consumables and operation performance. Lower concentration of chlorines in fuel will result in lower concentrationd of hydrochloric acid produced.

Barium Compounds 221112: Fossil Fuel Electric Power Generation 2005 1,633.00 1,472.00 -9.86% Barium 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 for beneficial use replacing other commercial products (e.g.cement) or used as raw material in the on-site aggregate manufacturing process. The 100% of the aggregate (final product- A-2 and A-2-4 Class) produced in 2005 was sold for different 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).

Sulfuric Acid (1994 And After "Acid Aerosols" Only) 221112: Fossil Fuel Electric Power Generation 2005 47,484.00 47,484.00 0% Hydrochloric acid aerosol (in flue gas) from the fuel combustion process is neutralized with water, limestone and hydrated lime , additionally with a Circulating Dry Scrubber for be removed as gypsum in the Electrostatic precipitator. The facility burn low sulfur coal (<1%) and low sulfur diesel (<0.05% ). The Best Achievable Control Technologies are installed to efficiently control the SO2 and sulfuric acid emissions. The facility continously evaluate the fuel %S to define the projected nuetralization chemicals injction target for tracking consumables and operation performance. Lower concentration of sulfur in fuel will result too in lower concentrations of sulfuric acid in the flue gas.

Ammonia 221112: Fossil Fuel Electric Power Generation 2005 209,986.00 226,186.00 7.71% Principal source of ammonia is the urea injection to control NOx emissions generating an ammonia slip (estimated). Continously monitoring operating performance against design and target of the consumables to flag high consumption events to internally investigate and implement performance improvement actions to keep in control the consumables (UREA) and Nox emissions. In this way is minimized the urea injection and generation of an ammonia slip consequence of an incomplete reaction.
