to the SIP by the ARB through Executive Order G-125-244. To meet the United States Environmental Protection Agency (U.S. EPA) criteria for determining that rule submittals are administratively
and technically complete, we have enclosed evaluations
of the effects of the rules on emissions, evaluations
of the rules’ consistency with 40 CFR 51, and other supporting documentation provided

to comply with the U.S. EPA’s SIP Completeness Policy. We understand that, according

to section
11 0(k)(

1 )(B) of the federal Clean Air Act, the U.S. EPA will determine within 60 days of the Administrator’s receipt of a SIP revision, but no later than six months after the date by which the State is required
to submit the revision, whether California Environmental Protection AgencyPrintedonRecycledPaperMs. Felicia Marcus December
