The Environmental Protection Agency (EPA) is proposing to approve two state implementation plan (SIP) revisions (Revision C16 and Revision I16) formally submitted by the Commonwealth of Virginia. These revisions pertain to amendments made to the definition of "volatile organic compound" (VOC) in the Virginia Administrative Code to conform with EPA's regulatory definition of VOC. Specifically, these amendments remove the record keeping and reporting requirements for t-butyl acetate (also known as tertiary butyl acetate or TBAC; Chemical Abstracts Service [CAS] number: 540-88-5) and add 1,1,2,2-Tetrafluoro- 1-(2,2,2-trifluoroethoxy) ethane (also known as HFE-347pcf2; CAS number: 406-78-0) as a compound excluded from the regulatory definition of VOC, which match actions EPA has taken. EPA is approving these revisions to update the definition of VOC in the Virginia SIP under the Clean Air Act (CAA).
