FROM: J. MICHAEL WALFORD, PUBLIC WORKS DIRECTOR
DATE: September 13, 1994
SUBJECT: FRANKLIN CANYON ROAD TANK REMOVAL, MARTINEZ
Project No.: 0662-6U4326
SPECIFIC REQUEST(S) OR RECOMMENDATION(S)& BACKGROUND AND JUSTIFICATION
I. Recommended Action:
A. APPROVE Amended Scope of Work for Purchase Order 67342 dated June 30, 1994,
with Subsurface Environmental Corp. to complete the removal and cleanup of leaking
underground storage tanks adjacent to Franklin Canyon Road at Wolcott Lane in
Martinez.
B. AUTHORIZE the Purchasing Services Manager to increase the current purchase order
with Subsurface Environmental from $23,000.00 to $40,000.00, plus or minus 10%.
II. Financiallmpact
The total cost of the-work is estimated to be $40,000.00 from Road Funds. Reimbursement
from the State of California and/or State Leaking Underground Storage Tank Fund is being
pursued.
III. Reasons for Recommendations and Background:
Approximately thirty-five years ago, the State of California relinquished to Contra Costa
County certain road right of way which the State had originally purchased for the
construction of Highway 4. Portions of this property are up to 300 feet wide on steep
upslopes. Because of the terrain, access is difficult and weed abatement and creek
maintenance are expensive. Public Works' Maintenance Division has requested the disposal
of all right of way not necessary for the integrity of Franklin Canyon Road. Abutting owners
have expressed an interest in purchasing the surplus and have funded the survey, appraisal
and processing of the sale which is currently underway.

SUBJECT. FRANKLIN CANYON TANK REMOVAL
Page 2
Recently the Health Services Department was notified of the possible existence of under-
ground storage tanks on the subject property. Upon investigation, staff confirmed the
existence of one 300-gallon and one 500-gallon tank; both tanks were estimated to be at
least sixty years old and initially presumed empty. A consultant was hired to remove both
tanks and to perform necessary soil and water testing under the direction of County
Hazardous Materials personnel. During removal, staff discovered that the smaller tank was
not empty and had over time leaked an unknown amount of petroleum product into the
surrounding soil. Proximity to Franklin Creek has further complicated the situation with a
high groundwater table.
Costs to remediate soil and possible groundwater contamination have exceeded original
estimates. The increased dollar limit on the purchase order is necessary to cover the costs
to perform additional testing, backfill the tank holes with clean soil and properly dispose of
contaminated soil and water.
IV. Consequences of Negative Action:
The project will not have sufficient funding to remediate a hazardous materials situation
with potential danger to public health and safety.
