This resolution requests that the Department of Natural Resources pause its ongoing process of promulgating California ACCII regulations. The Department is requested to determine the fiscal impacts of imposing the ACCII regulations on Delawareans. A further request is made that the Department evaluate the approach taken by Pennsylvania and Colorado, two states that, like Delaware, have chosen to follow California vehicle emissions regulations under Section 177 of the U.S. Clean Air Act. The Department is also requested to evaluate the protocol observed by 33 other states in following the EPA vehicle emission regulations. A report is requested to be provided to the General Assembly by March 15, 2024. Until the delivery of the report, it is requested no further action be taken towards promulgating the proposed ACCII regulations.
