Box 2040 Santa Maria, CA 93457-2040 P: (805) 346-1766 F: (805) 346-1767 May 8, 2021 Ms. Molly Brown, Haz Mat Inspector City of SLO Fire Dept. 2130 Santa Barbara Avenue San Luis Obispo, CA 93401 Subject: May 8, 2021 Laboratory Results for 2600 Broad Street, San Luis Obispo, CA. Dear Molly: Buena Resources, Inc. has summarized the five samples taken from the excavation corners and bottom after the five bins of impacted soils was removed. Samples were taken by staff from Pacific Petroleum California (PPC) on May 5, 2021 and delivered to OEC Laboratory in Santa Maria, CA. DISCUSSION OF RESULTS Three of the five samples, NW Corner, NE Corner and Center, reported total petroleum hydrocarbon (TPH) diesel range levels that exceed the 260 mg/kg action level for this site. In addition, the samples taken at the NE Corner, SW Corner and the Center require additional STLC testing to confirm if those samples are California hazardous for chromium and nickel. CONCLUSIONS Based on the above results, additional material needs to be excavated from this site to try to lower the hydrocarbon and metal levels, noted above, below the action levels for this project.
