DISCUSSION Government Restrictions The future of the cement industry will be greatly impacted in the next decade. Colosse currently meets the regulations made by the Environmental Protection Agency on emissions in cement production. However, proposals of more stringent restrictions on mercury emissions in kilns, and the inclusion of carbon dioxide in the list of harmful green house gases, or GHG’s, in the Clean Air Act, will force industry’s increased attention on emissions. These new restrictions are projected to occur within the next ten years, and need to be addressed immediately to ensure success in the future. Current Restrictions The industry is almost completely governed by the EPA. Most restrictions come from the Clean Air Act, Title 1 – Air Pollution Prevention and Control, but the industry is also governed by the National Emissions Standard for Hazardous Air Pollutants (2). The limitations under these regulations pertain mainly to air quality, ozone protection, and the prevention of significant deterioration. Title 1 of the Clean Air Act can be referenced for details on emissions and pollutants. Currently, under the Clean Air Act, carbon dioxide is not considered a pollutant. Future Restrictions Several proposed regulations require attention for the industries success. The rotary and shaft kiln play a large role in production, and have recently been subject to innovative optimization techniques, but are in danger of costing the industry millions. This new regulation will set new limits on the mercury emissions on new and existing kilns, and if passed, will cut emissions down by 81% (cementamericas). The proposed regulation has been considered unachievable, even with large investments from the industry, by the Vice President of Regulatory Affairs for the Portland Cement Association (cementamericas).

In a recent ruling carbon dioxide has been added to the list of pollutants classified as GHG’s. Through experiments and environmental analysis, carbon dioxide has been assessed as a threat to the public. This regulation has not yet been passed, but when passed, will cause significant reductions in carbon emissions from mobile and stationary sources (nytimes). Carbon dioxide was one of six gases assessed: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride. Further restrictions are in process from Congress. A bill to reduce greenhouse gas emissions from the production and use of energy, S. 1766, will also regulate cement production. This bill was introduced in 2007, and was sent to the Committee on Environment and Public Works (con). As cement production facilities rely on the use of coal power plants, attention to the future of this bill is required. Green Cement Technology As the EPA’s regulations on emissions from all industrial sectors have become more stringent, the cement industry has looked to optimize different areas of production. Green cement has been a recent innovation involving optimization in the areas of energy use, harmful emissions, and natural resources. By introducing substitutes for the limestone used in traditional cement, and
