Account Balance Adjustments 

Listed below are administrative adjustments to participants’ accounts in the LCFS Reporting Tool and Credit Banking and Transfer System.  The adjustments reflect corrections to inaccurately reported data discovered through audits or self reported to ARB.  In some instances the data correction retroactively improves a company’s credit balance; because the regulation does not allow such retroactive benefits, the credit account balance was administratively returned to its pre-correction status.

Date of Adjustment Company Name Description
May 10, 2017 Valero Marketing and Supply In 2016, Valero Marketing and Supply failed to report imports of ethanol supplied to California. Those volumes were added to the system. ARB then adjusted the credits generated by removing 2,708 credits from Valero's account.
May 3, 2017 Kern Oil and Refining Co. Between 2013 and 2015, Kern Oil & Refining reported production of Fuel Pathway Code RNWD003, renewable diesel from tallow.  ARB determined that production batches made using corn oil – a different feedstock than called for in the pathway – were not eligible to generate credits under any pathway.  15,838 credits corresponding to the ineligible batches were removed from Kern Oil & Refining Co.'s account.
April 4, 2017 Kinergy Marketing LLC In Q1 2016 volumes of ethanol were incorrectly reported while balancing gains and losses of inventory. ARB adjusted the credits generated by removing 64 credits from Kinergy's account.
March 30, 2017 WM Renewable Energy L.L.C. In Q3 2016, WM Renewable Energy overreported LNG volumes.  The company corrected the volumes in the system which temporarily resulted in a net loss of 607 deficits. ARB then added these 607 deficits to WM Renewable Energy's account.
February 7, 2017 Crimson Renewable Energy LP The fuel volumes reported by Crimson Renewable Energy LP between 2012 and 2016 had not been corrected for temperature.  Crimson recalculated to account for temperature, reducing the volumes and the corresponding credits by 4,405.
