Values marked our reading are our classification of what the source says — the source does not print them in those words. The quote below is the evidence for each one; judge it yourself.
What the source says
This action promulgates national emission standards for hazardous air pollutants (NESHAP) for new and existing plant sites that manufacture flexible polyurethane foam. The original technology-based rule, issued in 1998, controlled emission of methylene chloride, 2,4-toluene diisocyanate (TDI), methyl chloroform, methylene diphenyl diisocyanate (MDI), propylene oxide, diethanolamine, methyl ethyl ketone, methanol and toluene. Methylene chloride comprised over 98 percent of the total hazardous air pollutant emissions from the industry.
