N Canepa's Car Wash 2 Claim No. 019982 Fund closed Claim No. 8449 on December 19 , 2011 , because Canepa's Car Wash received the maximum reimbursement per occurrence for the claim . UST System #2 In April 1993 Canepa's Car Wash installed a new UST system (three 12 , 000-gallons) , which I will refer to as UST System #2 . On March 6 , 2012 , San Joaquin County concluded a probable second release occurred between 1998 and 2002 from UST System #2 . On October 17 , 2012 , the Fund received a claim application . Our investigation confirmed a subsequent release occurred from UST System #2 ; however, the second release for Claim No. 19982 was not a separate occurrence from the first release funded under Claim No . 8449 . Discussion Occurrence Section 25299. 19 of Chapter 6 . 75 , Division 20 of the California Health and Safety Code defines "occurrence' as follows : "An accident, including continuous or repeated exposure to conditions , which results in an unauthorized release of petroleum from a UST. Unauthorized releases at the same site which require only a single site investigation shall be considered as one occurrence . An unauthorized release subsequent to a previous unauthorized release at the same site shall only be considered a separate occurrence if an initial site investigation has been completed for the prior unauthorized release . Initial Site Investigation Section 2804 of Chapter 18 , Division 3 , and Title 23 of the Petroleum UST Fund Regulations defines " initial site investigation" as follows : "A soil and groundwater investigation sufficient to identify where contamination resulting from an unauthorized release is most likely to be present. " Based on the Fund 's review of the application and supporting documentation submitted , the initial site investigation for UST System #1 had not been completed in 2002 . This is evident based on the following correspondences from San Joaquin County relating to UST System #1 : • On October 28 , 2004 , the County approved the remedial action plan for soil and groundwater. • By letters dated December 1 , 2008 , and May 18 , 2011 , respectively, the County directed Canepa's Car Wash to submit a work plan to complete the lateral delineation of impacted groundwater.
