tert-butyl Alcohol (tert-butanol) is used as a solvent; as a denaturant for ethanol and several other alcohols; in the manufacture of flotation agents, fruit essences, and perfumes; as an octane booster in gasoline; as a dehydrating agent; and as a chemical intermediate in the manufacture of methyl methacrylate. tert-Butanol's production for industrial uses may result in its direct release to the environment through various waste streams. tert-Butanol is also a likely degradation product of methyl tert-butyl ether (MTBE). Probable routes of human exposure to tert-butanol include inhalation, ingestion, and skin or eye contact.
|Aug 2013||EPA released Preliminary Assessment Materials (draft literature searches and associated search strategies, evidence tables and exposure response arrays) for discussion at an IRIS Public Science Meeting.|
|Dec 2013||EPA discussed tert-butanol at the December 2013 IRIS public science meeting.|
|Sep 2014||EPA sent an interagency science consultation draft for review and comment.|
|May 2016||EPA released the public comment draft for public review and comment. It is also a topic of discussion for the May 10, 2016 IRIS Public Science Meeting.|
Following public comment and external peer review, the assessment will be revised taking into consideration peer review and public comments. The assessment will then undergo a final EPA internal review and a review by other federal agencies and the Executive Office of the President. Once final, the assessment will be posted to the IRIS database.
