Advanced Clean Cars II Regulations; (23 page(s), in English)

Proposed rule - Amends and extends rules to further reduce harmful pollution from light-and medium-duty motor vehicles. The proposed regulations will increase the stringency of existing regulations to ensure emissions are reduced under a wider range of conditions under which vehicles are used and will transition new light-duty vehicle sales in California to 100% zero-emission by 2035. In addition to the substantive proposals, several conforming changes are proposed to related regulations to maintain consistency with existing regulations and maintain existing requirements in regulations that are not being proposed for amendment.
