The Environmental Protection Agency (EPA) is amending the EPA's regulatory definition of volatile organic compounds (VOC) under the Clean Air Act (CAA). The regulatory definition of VOC currently excludes t-butyl acetate (also known as tertiary butyl acetate or TBAC; CAS Number: 540-88-5) for purposes of VOC emissions limitations or VOC content requirements on the basis that it makes a negligible contribution to tropospheric ozone formation. However, the current definition includes TBAC as a VOC for purposes of all recordkeeping, emissions reporting, photochemical dispersion modeling and inventory requirements which apply to VOC. This final action removes the recordkeeping, emissions reporting, photochemical dispersion modeling and inventory requirements related to the use of TBAC as a VOC.
