On October 1, 2015, the Environmental Protection Agency (EPA) promulgated a revised National Ambient Air Quality Standard (NAAQS) for ground-level ozone at a level of 0.070 parts per million (ppm). Pursuant to sections 110(a)(1) and 110(a)(2) of the Clean Air Act (CAA), each state is required to submit to the EPA a State Implementation Plan (SIP) to provide for the implementation, maintenance, and enforcement of a newly promulgated or revised NAAQS. This SIP revision fulfills this requirement
relative to the 2015 ozone NAAQS. This SIP revision further demonstrates how Delawares SIP satisfies CAA 110(a)(2)(D)(i)(I), also known as the good neighbor provision. In particular, the good neighbor provision requires each state to demonstrate that emissions from sources within that state do not contribute significantly to nonattainment in, or interfere with maintenance by, any other state with respect to a particular NAAQS. In this SIP revision, Delaware shows it satisfies the good neighbor provisions for the 2015 ozone NAAQS by showing that all non-trivial sources of emissions of nitrogen oxides (NOx) and volatile organic compounds (VOCs) in Delaware are well controlled.
