FIRE DEPARTMENT REVIEW OF SOIL INVESTIGATION AND REMOVAL AT 2600/2640 BROAD ST, SAN
LUIS OBISPO, CA: APN 004-925-036
The City of San Luis Obispo Fire Department has reviewed the report titled Closure Report, Diesel
Tank & Contaminated Soil Removal, 2600 Broad St, San Luis Obispo, CA (Rev.3) prepared by Buena
Resources, Inc. on December 11, 2021. We make the following conclusions and determinations based
on our review:
• An approximate 4'-diameter by 8'-long cement -filled underground storage tank (UST)
believed to have once stored diesel fuel was found and removed. Hydrocarbon -impacted soil
discovered during the tank excavation was removed and disposed of at a Class I landfill under
hazardous waste manifest. Confirmation soil samples collected from the sidewalls and
bottom of the resulting approximate 8'x8'x8' excavation indicated Contaminates of Concern
(COCs), including Total Petroleum Hydrocarbons as gasoline, diesel, and motor oil (TPHg,d,o),
Volatile Organic Compounds (VOCs), and CAM17 metals, were below San Francisco Bay
Regional Water Quality Control Board (SFBRWQCB) Tier 1 Soil Environmental Screening
Levels (ESLs).
• Additional impacted soil was discovered during construction of a 3' deep trench for the
installation of a fire water line. Half of the trench contained brick and other debris and was
designated "Sump Trench". Initial soil sampling indicated elevated levels of chromium, lead,
and nickel. With the singular exception of the "Sump Trench West Wall Sample" collected on
4/6/2021 which indicated lead at 380 mg/kg above the ESL of 320 mg/kg (non -cancer
hazard), confirmation soil samples after additional excavation indicated concentrations of
heavy metals well below SFBRWQCB Commercial/Industrial Shallow Exposure ESLs.
• During excavation work on the trench, an adjacent concrete slab was uncovered, sampled,
and removed. The concrete slab, along with tiles found within the excavation, was sampled
for asbestos with all results indicating asbestos was not present in the material. Additional
hydrocarbon -impacted soil was discovered underneath the concrete slab and was removed.
Confirmation soil samples collected from 12' at the bottom of the concrete slab excavation
indicated concentrations of COCs below Commercial/Industrial Shallow Exposure ESLs.
• Groundwater was not sampled during soil removal activities.
• The site is being redeveloped into a commercial cannabis retail facility. The excavation areas
noted above have been backfilled, paved, and will be utilized as a parking lot.
Based on the review of the above information, no further action is required at this time contingent
upon the existing designated land use as commercial/industrial and the information provided in the
listed report is accurate and representative of site conditions.
Further action will be required if hazardous materials/waste that impact soil or groundwater are
discovered on site or the property is redeveloped. Action required by this department may include,
but is not limited to, a review by this department, additional investigation, mitigation or remedial
action, groundwater sampling, feasibility study and human health risk assessment. If you have
questions concerning this letter, please contact me at (805) 781-7383.
