SUBJECT: TREATMENT OF SOIL FOR LYONS AVENUE PROJECT 89-13
REQUEST FOR BUDGET TRANSFER
DEPARTMENT: COMMUNITY DEVELOPMENT
BACKGROUND
During the construction of Lyons Avenue Road widening project. approximately 100
cubic yards of soil was encountered at the base of the slope and drainage
easement which contained unacceptable levels of soluble lead. It appears that
this "contamination" occurred gradually over the years as a_result of drainage
runoff from Lyons Avenue.
The following four soil -treatment alternatives have been reviewed by Staff:
• Option 1: Disposal to a Class 1 hazardous landfill. Exercising this
option will subject the City to long-term liability and annual taxes. As
a hazardous waste generator, the City would be financially responsible, on
a percentage' basis, for any future landfill closure improvements.
Estimated Cost (Disposal Only): $55,000
• Option 2: On-site stabilization treatment and Class 3 landfill disposal.
This option consists of chemically treating the soil on-site, then
transporting it to a Class 3 landfill. Estimated cost: $60,000
• Option 3: On-site stabilization treatment and disposal on-site. This
option consists of chemically treating the soil on-site, and disposing it
on adjacent property, subject to the owner's approval. Estimated cost:
$45,000
• Option 4: 0£f -site stabilization treatment. This option consists of
transporting contaminated soil to Gibsons's oil refining facility in
Bakersfield (provided that the soil meets Gibson's permit requirements),
where it will chemically treated and then sold by Gibson as road
material. Estimated cost: $17,500
We have been informed (verbally) that Gibson's permit allows them to treat the
soil from our project. Quotes have been received for Option 4, with Earth
Systems Environmental being the low bidder. Staff therefore recommends
proceeding on this basis. Since a number of formalities must be satisfied
before this material can be transported to Gibson Oil, it anticipated that
this work will not be completed until February 1992.

$10,000 for soils investigations and laboratory testing, $17,500 for soil
treatment and disposal, $4,500 for soils inspection, and $10,000 for
contingencies.
Although the current budget does not provide for funding for this project,
support for Project 89-13 in the amount of $50,000 was negotiated as part of a
recent agreement for settlement with Dale Poe Corporation. The additional
$5,000 to complete the project, if necessary, is available in Miscellaneous
Projects Account 25-96056-227.
Approve the off-site stabilization soils treatment procedure (Option No. 4), and
authorize entering into a contract with Earth Systems Environmental, Inc. to
perform this work, and authorize budget in the amount of $55,000 from Account
25-96056-227 to 25-96033-227 for the completion of Project 89-13.
