Emission of butanone was regulated in the US as a [[hazardous air pollutant]], because it is a [[volatile organic compound]] contributing to the formation of [[tropospheric]] (ground-level) [[ozone]]. In 2005, the [[US Environmental Protection Agency]] removed butanone from the list of [[hazardous air pollutant]]s (HAPs).<ref>Federal Register Volume 70, Issue 242 (December 19, 2005)</ref><ref>{{cite web|author1=Barbara Kanegsberg |title=MEK No Longer a HAP |url=http://www.bfksolutions.com/index.php/newsletter/archived-newsletters/133-mek-no-longer-a-hap |publisher=Bfksolutions newsletter |access-date=2 April 2015 |date=n.d. |url-status=dead |archive-url=https://web.archive.org/web/20150402144959/http://www.bfksolutions.com/index.php/newsletter/archived-newsletters/133-mek-no-longer-a-hap |archive-date=2 April 2015 }} After technical review and consideration of public comments, EPA concluded that potential exposures to butanone emitted from industrial processes may not reasonably be anticipated to cause human health or environmental problems.{{citation needed|date=March 2015}}</ref><ref>{{Cite web|url=http://www.pcimag.com/articles/85504-epa-de-lists-mek-from-caa-hap-list|title=EPA De-Lists MEK from CAA HAP List|website=www.pcimag.com|access-date=2016-07-30}}</ref>
