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.
