The group worked with the State environmental agencies in each of the six Region 5 States to develop an inventory of the sterilization sources in the Region that are subject to the new standards. The workgroup developed an information package on the standards, and in July 1996, this package was mailed to the sterilization sources on the inventory, as well as several trade associations. To the best of our knowledge, the information is correct and current as of June 1, 1998.
Ethylene oxide is designated as a hazardous air pollutant.
Which emission standards apply to you depend on whether or not you use 10 or more tons of ethylene oxide per year. Please note that how the standards apply to you is based on ethylene oxide usage , not ethylene oxide emissions. The basis here is different from that used to determine whether you are a major or area source. The performance testing is conducted with the methods and procedures in Sections 63.7 and 63.365. Performance testing will determine the values to be used for compliance monitoring at your facility.
