Abstract
The Environmental Protection Agency (EPA) is approving two state implementation plan (SIP) submissions submitted by the State of Delaware. The first submission addresses the basic program elements, including, but not limited to, regulatory structure, monitoring, modeling, legal authority, and adequate resources necessary to assure attainment and maintenance of the National Ambient Air Quality Standards (NAAQS). This type of SIP submission is referred to as an infrastructure SIP submission. Delaware made this submission in order to address the infrastructure requirements for the 2015 ozone NAAQS. EPA is approving Delaware's infrastructure SIP submission in accordance with the requirements of Clean Air Act (CAA) section 110(a). EPA is also approving a second submission from Delaware which updates a reference to the current version of EPA's modeling guidance.
