Preparation, Adoption, and Submittal of State Implementation Plans; Appendix M, Test Method 207

The purpose of this proposed rule is to add a validated stationary source test method for the measurement of isocyanate emissions from stationary sources to the Code of Federal Regulations. This method, validated according to EPA Method 301 criteria, would be used to reliably collect and analyze gaseous isocyanate emissions from stationary sources such as flexible foam manufacturers, automobile paint spray booths, and the pressed board industry. Specifically, methylene diphenyl diisocyanate (MDI), methyl isocyanate (MI), hexamethylene 1,6-diisocyanate (HDI), and 2,4-toluene diisocyanate (TDI) are the gaseous pollutants in source emissions to be measured. The test method is entitled, ``A Method for Measuring Isocyanates in Stationary Source Emissions,'' and will be added to 40 CFR Part 51, Appendix M, as Test Method 207. This method will provide a tool for state and local governments, representatives of private industry, and the U.S. Government to reliably monitor stationary sources for isocyanate emissions with a validated stationary source method. Additionally, this method will allow the U.S. Environmental Protection Agency to comply with the requirements of the Clean Air Act Amen
