(TEM) completed waste stream sampling and <br />classification at eight SBC locations in California (SITES). The objective was to select a random sample <br />of sites, which would act as a representative matrix of all SBC locations, to perform waste stream <br />classification for the purpose of self -declaration of all water intrusion in spill buckets at all SBC facilities. <br />This report summarizes the sampling activities and analytical results and can act as supporting <br />documentation for future classification of the water intrusion waste stream as hazardous or non- <br />hazardous. <br />Samples were collected from eight (8) California facilities in total (4 Southern California, 4 Northern <br />California). <br />NORTHERN CA <br />1. DAVLCA13 <br />3900 Blackhawk Plaza Circle, Danville, CA <br />2. RCMDCA11 <br />2105 Macdonald Ave, Richmond, CA <br />3. SNLNCAII <br />15125 Hesperian Blvd, San Leandro, CA <br />4. SNRFCA01 <br />220 Shafer Street, San Rafael, CA <br />At each of the four Northern California facilities, a sample was collected from the spill bucket in <br />accordance with the California Regional Water Quality Control Hoard. The collected sample consisted of <br />8 VOAs and one 250 mL poly bottle. The sample containers were labeled, packed in ice and shipped via <br />overnight delivery to Sun Star Laboratories, located in Tustin, CA, to be analyzed for EPA Method 8015cc <br />(carbon chain), and to MBC Applied Environmental Supplies, located in Costa Mesa, CA, to be analyzed <br />using a DOHS Title 22 Fish Bio Assay. <br />SOUTHERN CA <br />1.

Chapman Avenue, Orange, CA <br />At the four (4) Southern California facilities, samples were collected by simulating a static test, as there <br />was not enough water found in the spill buckets to collect a sample directly. The simulated static test was <br />conducted by filling the spill bucket with approximately 2 gallons of tap water and waiting about 15 <br />Engineering • Environmental • Compliance - Construction <br />701 N.
