Subject: April 23, 2021 Laboratory Results for 2600 Broad Street, San Luis Obispo, CA.
Dear Molly:
Buena Resources, Inc. has summarized the eighteen samples taken from the five 20 cyd
bins (3/bin) of material that was removed from this site. Additional samples have been
taken from the walls and bottom but we don't have that data as yet. Samples taken from
these bins all required additional testing for both STLC and TCLP testing for both
chromium, copper and lead. Samples were taken by staff from Pacific Petroleum
California (PPC) on April 23, 2021 and delivered to OEC Laboratory in Santa Maria, CA.
DISCUSSION OF RESULTS
Based on the results obtained from the bin sampling, all the material would be
considered California hazardous for lead but not RCRA hazardous. In four of the
samples, the TTLC lead levels were high enough that the material did not have to be
analyzed further for soluble levels. Those samples were Bin 2094-A, Bin 20340-C, Bin
20158-C and in Bin 20376-B. Those TTLC lead levels ranged from 1100 mg/kg-8000
mg/kg. STLC lead levels ranged from 10 mg/1-120 mg/I.

CONCLUSIONS
All of the material removed and placed into the five 20 cyd bins is considered California
hazardous for lead, but not RCRA hazardous. All of this material would require disposal
at a Class I TSD facility.
Thank you for the opportunity to be of service. If you have any questions, please contact
this office at (805) 346-1766.
Sincerely,
Buena Resources, Inc.
