INTRODUCTION
This report recommends that the city Council authorize the City
Manager to negotiate and execute a contract with Dames and Moore
Consulting Engineers to conduct a landfill compliance program and
gas recovery feasibility study of the Santa Monica landfill in
the amount of $201,040 as mandated by the State of California.
BACKGROUND
One of the city's budgeted capital projects is the implementation
of a landfill compliance and gas recovery feasibility study for
the old city landfill located at 2500 Michigan Avenue. The City
Council appropriated funds in the amount of $250,500 to conduct
this study in the Fiscal Year 1989-90 eIP budget.
The purpose of this study is to bring the City's landfill
facilities which were closed in 1970 into regulatory compliance
with requirements of the state. The Calderon Act requires that a
Solid Waste Assessment Test (SWAT) study be performed to
characterize possible contamination of surface and ground waters,

soil, and air within a one-mile radius of a landfill. Article 5,
Subchapter 15, Title 23 of the California Code of Regulation
requires ground water monitoring programs for closed landfills.
The regional Water Quality Control Board which oversees
compliance with these regulations requires that the SWAT study of
the Santa Monica landfill be completed by 1991. The study will
take approximately fifteen months to complete.
The City's landfill, although closed for approximately twenty
years, produces landfill gas. The study will also evaluate the
feasibility of recovering this gas for a cogeneration project.
The estimated cost of this study is $201,040, of which $93,000 is
the cost of the landfill gas recovery feasibility portion of the
study. This cost is based on the city's and Consultant's best
estimate of the field work which will be required. The cost may
increase if the estimated number and depth of monitoring wells
and level of analytical services required to complete the study
exceeds what is originally determined necessary. The study will
provide the city with information on the degree of risk, if any,
posed to the environment by the refuse buried in the landfill as
well as provide a preliminary design for a gas collection system
to mitigate any nuisance landfill gas production.
CONSULTANT SELECTION
Staff prepared a Request for Proposal to conduct a Master Plan
Study and sent it to 9 consultants in December 1989. Staff
received 7 proposals to conduct the study. A committee
consisting of Stan Scholl, Director of General Services, Desi

Alvarez, city Engineer, and Neil Miller, Maintenance Manager,

study.
