Ground Zero Analysis, Inc. <br />SITE SAFETY PLAN <br />1 <br />An illicit discharge of diesel fuel to the storm drain system of Lionudakis, Firewood, Inc. (Site) was <br />reported to San Joaquin County in 2007. The alleged discharge was reported to have entered a <br />storm drain inlet located north of the above ground storage tanks (ASTs) and entered a storm water <br />pond. The ASTs are located on the west side of a 3.22 -acre parcel (APN 24712020) and the storm <br />water pond was located on the west side of a 9.63 -acre parcel (APN 24712008). The effluent piping <br />to the abandoned storm water basin was removed and the storm drain system routed to a new storm <br />water basin constructed on the northern end of a 10 -acre parcel (24712006). <br />On September 2, 2009, the San Joaquin County Environmental Health Department advanced three <br />(3) soil borings (B1, 132, and B3) within the confines of the abandoned storm water basin. Ground <br />Zero Analysis, Inc. (Ground Zero) reviewed EHD field notes. The field notes indicated that the <br />borings were advanced to 14, 20, and 16 feet below grade surface (bgs), respectively. Soil and <br />water samples were collected from the culvert (pit) located just south of boring B2. The "pit" was <br />the last catch basin in the storm drain system before storm water entered the storm water basin. <br />Task 1: Advance up to ten direct push soil borings and collect soil samples for <br />classification and laboratory analysis <br />Task 2: Flush and analyze water within the storm water drain system <br />Task 3: Excavate, haul, and backfill contaminated soil zone within the abandoned storm <br />water basin <br />JOB HAZARD ANALYSIS AND SUMMARY <br />Chemical Hazards <br />TASK(S) <br />CHEMICAL <br />PEL/STEL/IDLH <br />KNOWN <br />SIGNS/SYMPTOMS <br />(SOIL, WATER, AIR, <br />CONCENTRATION <br />ETC.) <br />1,3 <br />TPHd <br />None Established <br />9,600 ppm (soil) <br />Skin and respiratory irritation; <br />dizziness, nausea, headache, <br />CNS depression. <br />PAGE 4 <br />
