California Gasoline Program Procedures Documents and Predictive Models

This page last reviewed March 6, 2013

Background:

This page contains information about the California Predictive Model spreadsheets which are used to comply with the California reformulated gasoline (CaRFG) regulations . The 2007 amendments to the Phase 3 California Reformulated Gasoline Regulations (CaRFG3), including the CaRFG3 Predictive Model, were implemented on December 31, 2009.
The links below contain the spreadsheets for the Phase 2 and Phase 3 Predictive Models, and the supporting documents. The supporting documents show the equations that constitute the Phase 2 and Phase 3 models, the method of using the predictive models, and the equivalency criteria used in approving complying gasoline.
ARB uses an electronic reporting system in which the producers and importers submit electronically to ARB the properties of the CaRFG3 Predictive Model formulations they intend to produce. The Predictive Model spreadsheets used by the producers and importers have been revised to include the forms needed by the producers and importers to report electronically. The forms attached to the spreadsheets are filled out by the producers or importers and e-mailed to the ARB Enforcement Division. For producers please see the California Reformulated Gasoline Electronic Reporting Users's Guide for Producers and for importers please see the California Reformulated Gasoline Electronic Reporting Users's Guide for Importers in the links below.
The spreadsheets for CaRFG3 are categorized for producers, importers, and small refineries.
