• Non-Contact Cooling Water Elimination - Investigate the feasibility of a non-water
cooling system for the oxygen plant and the power station.
Replacing the water-cooled compressor in the oxygen plant with an air-cooled
compressor;
Installing a heat exchanger that uses the cold oxygen and nitrogen generated
by the oxygen plant; and
Installing the closed-loop "radiator" cooling system for all the generators.
• Cooling Water Optimization - Investigate ways to reduce the quantity of water
needed for cooling and lost to evaporation and blowdown. Some options to explore
are:
Replacing the O.S-inch diameter pipe that delivers the cooling water to the
rolls with smaller orifices or spray devices with self-cleaning nozzles;
Increasing the concentration cycle of the cooling towers; and
Decreasing blowuown quantity.
Storm 'Vater, Solid Waste, and Air Emissions
Develop and implement the following practices to minimize storm water run-on and run-off
and maximize collecting and treating storm water runoff for reuse, recycling solid wastes,
and air pollution control.
• Storm Water Managcment - Minimizing thc contamination of storm water and
reducing the quantity of contaminated storm water leaving the facility's site by:
Collecting, treating, ami reusing the storm water;
Grading anu contouring the site to minimize storm water run-on and runoff;
Constructing covered storage areas with concrete pads and containment
dikes for the iron oxide scale to prevent storm water contamination and
reduce dust pollution; and
Improving storage and handling procedures to reduce fuel oil spills.
• Solid Waste Reduction - Reducing the quantity of solid waste stockpiled by:
Reusing the iron oxiue in the furnaces or recycling slag and iron oxide by
selling to cement plants or marketing the slag as road material and the iron
oxiue as soil fertilizer;
