Contingency Fund, $7,500 from the CMWD Retained Eamhgs Fund, and $7,50(
from the Sanitation Enterprise Fund to the Vehicle Maintenance Fund, Accoun
001-620-5210-2493, and appropriating the total amount; and authorizing thc
City Manager to execute an agreement with MV Environmental for the remova
of the underground fuel storage tank at 405 Oak Avenue.
ITEM EXPLANATION:
During the testing and maintenance process of the City's underground fuel storagf
tanks, it was discovered that the underground tank located at 405 Oak Avenue wa:
leaking. Further investigation revealed that the ground water at this site wa:
contaminated from this leaking tank. The discovery of the leaking underground tad
required immediate notification to the County Hazardous Materials Managemen
Division and the Water Quality Control Board. A plan for remediation has beer
established with the County of San Diego Hazardous Materials Management DivisioI
by MV Environmental, Inc., the City's Hazardous Waste Consultant on this project.
The 405 Oak Avenue Yard is the property of the Water Enterprise Fund. Water initiallj
was the major tenant but has had a diminishing presence at that site over the years
Presently there are no Water employees or affiliations at the yard, and there are nc
plans for Water to return in the foreseeable future. Sharing the remediation costs wa:
suggested as the most equitable solution to this problem.
A detailed plan and an estimate of costs for remediation has been submirted to the City
and has already met with County approval. This preliminary investigation and repor
was conducted by MV Environmental. It is staff's recommendation that the CitJ
proceed with this plan designating the current consultant as a sole source vendor
Staffs recommendation is based on the Consultant's preliminary investigation, and tht
fact that the plan has met with approval by the County. Additionally, M
Environmental has already established effective working relationships with persons kej
to this project, including staff from the County Hazardous Materials Managemen
division, the Water Quality Control Board, and the City, and has completed several
successful projects for the City.
FISCALIMPALT:
Removal of the tank and remediation of the contamination is estimated to cost $20,000
An additional $10,000 is requested for contingency. Implementation of staff:
0 0 PAGE2OFAB# //39t/ 1
recommendation would require that $1 5,000 be transferred from the Unencumberec
Contingencies Fund, leaving a balance of $1,055,313; $7,500 be transferred from thc
CMWD Retained Earnings Fund, leaving a balance of approximately $3,000,000; an(
that $7,500 be transferred from the Sanitation Enterprise Fund. This combined amoun
will be transferred to the Vehicle Maintenance Fund. Approximately $20,000 ha
already been spent in the preliminary investigation of the contamination and thc
definition of its limits. Future costs will be borne by the Vehicle Maintenance Fund an(
will cost approximately $10,000 per year for the next five (5) years to continuall:
monitor the contaminated ground water.

Cost Proposal for Remedial Action at 405 Oak Street, Carlsbad, California: HMMD Case #Ho4977-001
Pursuant to your request of April 6, 1992, we have prepared tk
proposal to initiate remediation work at the referenced site.
This cost proposal is based on the outlined scope of services our Work Plan dated August 26, 1991 presented to Hazardc
Materials Management Division (HMMD) site specialist, Mr. Richa
Gilb. On September 11, 1991 Mr. Gilb informed our office that t
work plan met with their approval.
The following is a breakdown of services to be performed in th phase:
1. MV Environmental, Inc. will file a permit application for t closure and removal of one 2,000-gallon underground storage ta
(UST) with the Carlsbad Fire Department and the County HMMD.
2. We will employ a contractor with a 40-hour OSHA health a safety training certificate to demolish the pump islan excavate the 2,000-gallon fuel tank, and remove an estimated 1
cubic yards of gasoline contaminated soil using a trackhoe wi
street pads. Once the island is removed and the tank
exposed, a certified tank cleaner will dry ice the tank a
clean it. The waste water resulting from the cleaning operati
will be transported under manifest to the cleaner's facili where they have a discharge permit for disposal. A front e
loader will be used to stockpile the excavated soils in appropriate location on-site as to not disrupt normal activi
of the maintenance yard.
3. We will employ a mobile laboratory to perform on-site te analyses for Total Petroleum Hydrocarbons as well as benzen toluene, ethylbenzene, and xylene concentrations on sampl
collected from sidewalls and bottom of the excavation a
stockpiled soils.
approximately 15 to 18 feet below the surface. Sidewall a bottom samples will be collected during the excavation proce to demonstrate removal of petroleum hydrocarbon contaminat soils above the remediation action level (RAL) of 1000 mg/kg f soil in a non-beneficial groundwater use area.
We anticipate removing soils to a depth

analyzed in the mobile laboratory for Total Petroleum Hydrocar
bons (TPH) using EPA Modified 8015 method with the highest TF sample being further analyzed for benzene, toluene, ethyl
benzene, and xylenes (BTEX) usiny ERA method 8920,
4. The estimated 150 cubic yards of contaminated soils will k stockpiled on-site at a designated area chosen by the flec operations manager. The soils will be randomly sampled bas€
on the countyls one representative sample per 25 cubic yards c soil. We anticipate collecting six random samples for analyses Samples will be analyzed for TPH, with the highest sampl
further analyzed for BTEX using the above referenced test ar
for organic lead content. The soils will be stockpiled on tk asphaltic concrete parking lot using a front end loader ar covered with six-mil plastic sheeting.
5. Once confirmation samples verify the removal of the highes
contaminated soils, the excavation will be backfilled usir
import rock and non-expansive soil - approximately 80 to 1C
cubic yards of one to three-inch crushed rock to an elevatic
of two feet above existing groundwater elevation. The remainir
estimated 60 to 85 cubic yards of non-expansive D-G. soils wil
be compacted and tested by MV Engineering, Inc.. An addendL compaction report will accompany our Remediation Action Repoi
certifying the fill of the excavation.
6. Upon completion of the above stated scope of work, a detail€
report of our field activity, laboratory results, and recon
mendations concerning the stockpiled soils will be provided.
7. Approximately 30 days after the removal of the contaminatc
soils has been completed, we propose to develop and sample ti
seven groundwater monitoring wells at the site. Purged watc
will be contained in 55-gallon drums, labeled, and left on-sitc They are the responsibility of the generator. The groundwatc
samples will be collected according the county guidelines ar
stored in a cooler on blue ice prior to transport to a certific analytical laboratory accompanied by the proper chain-of-custoc
forms. Each sample will be analyzed for TPH and BTEX using EI
method 8015/8020.
All site activities, permits, sample collection, and analysj procedures will comply with the current guidelines and regulatior in effect for the County of San Diego.
Upon completion of the groundwater sampling activities and receil
of the laboratory analysis, MV Environmental, Inc. will issue thrc
copies of the Remediation Action Report to the client and one coy

on-site. Disposal of the drums and their contents is th
responsibility of the property owner.
