The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision submitted by the State of Delaware. This revision pertains to amendments made to the definition of volatile organic compounds (VOC) in the Delaware Administrative Code to conform with EPA's regulatory definition of VOC. EPA found that certain compounds have a negligible photochemical reactivity and, therefore, has exempted them from the regulatory definition of VOC in several rulemaking actions. This revision to the Delaware SIP requests the exemption of eight compounds from the regulatory definition of VOC to match the actions EPA has taken. In addition, the revision also requests to remove the recordkeeping, reporting, modeling, and inventory requirements for t-butyl acetate (TBAC). This action is being taken under the Clean Air Act (CAA).
