Judgment denying plaintiff's petition for writ of mandate to set aside defendant's ordinance banning single-use plastic bags and imposing a fee on single-use paper bags, for failing to comply with the California Environmental Quality Act (CEQA), is affirmed, where: 1) the ordinance constitutes a regulation enacted for the purpose of protecting natural resources and the environment which qualifies as an exemption from CEQA; and 2) the administrative record contains substantial evidence to support the conclusion that the ordinance is an action that will maintain, enhance, and protect natural resources as well as the environment generally.
