I initially contacted Enesta Jones, but got a bounce-back message saying she was out of the office and directing me to this email account. I have a few questions for a story that I'm trying to do on the subject of ultrafme particles, and the extent to which they're a health concern. Q: I've seen it said in some other news articles that the EPA doesn't regulate or set limits on ultrafme particles (0.1. microns in size), though it sets air quality standards for larger particles. Is that accurate? Q: Has there been any recent consideration of creating a standard for ultrafme particles? If so, what stage is the agency at in the process? Also, I'm wondering if you can put me in touch with an agency expert on this subject. regards, Patrick J. Kiger 240-235-6203 (office) www, patrickj ki ucr.com Twitter: @PatrickJKiger Sierra Club v.
