Abstract
The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the State of Delaware. This revision pertains to amendments made to the definition of "volatile organic compound" (VOC) in the Delaware Administrative Code to conform with EPA's regulatory definition of VOC. The 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, as discussed below. This revision to the Delaware SIP requested the exemption of these compounds from the regulatory definition of VOC to match the actions EPA has taken. The revision also requested minor changes to the format of some of the chemical formulas for VOCs that are already excluded from the definition of VOC in the Delaware SIP. EPA is approving these revisions to update the definition of VOC in the Delaware SIP under the Clean Air Act (CAA).
