EVALUATION MONITORING PLAN AND REPORTING SERVICES AND
ECONOMIC ANALYSIS UPDATE SERVICES
FOR THE CALIFORNIA STREET LANDFILL
ATTACHMENT A
AMENDED SCOPE OF WORK
Attachment A - Scope of Work
3D GeoServices understands that this amended agreement is for the period April 1, 1999 through
Septemb , 1999, to commence upon authorization from the City of Redlands (City). The
agreement, will require submittal of a D rtion tr tion Report, Release Vel and
contngrl Evaluation Monitoring Plan (EMP), and reporting and economic analysis update
services for submittal to the SARWQCB and the lead enforcement agency(LEA)for the California
Integrated Waste Management Board (CIWMB). This attachment describes the agreement scope
of work for the EMP and economic review services.
Task 1 - Economic Analysis Update - Task 1 consists of updating the 1996 landfill
resource evaluation, which evaluated the costs and benefits of landfill operation and expansion,
versus closure. This update will reflect current regulatory impacts, operations and maintenance
costs, reporting costs, and expansion needs. This evaluation will incorporate the City's revised
closure and post-closure cost estimates. The costs and benefits evaluation will be projected
throughout the active life of the landfill (which includes the post-closure maintenance period)and
will be given in present-value terms on an annualized basis, with the base case presentation given
at the City's current tipping fee rate schedule. This task will consist of updating the database and
spreadsheet numbers with current budget information, and two evaluations. Each evaluation will
each contain three potential scenarios, for a total of six revisions. (leo chihg�)
Task 2 - Economic Analysis Interface-Task 2 consists of preparing the analysis update
from Task 1 for transfer to a third party consulting firm for continuing analysis. This task will
specifically consist of familiarizing the firm with the budget considerations in the current model.
It will also include converting the current spreadsheet program to a new format, such that the
assumptions, background information, and economic data and factors, are transferred compatibly
from the current analysis. (No changes)
Task 3 - SARWQCB Work Plan-Task 3 consists of preparing and submitting a work plan
to the SARWQCB,in accordance with their regulatory requirements,describing the proposed aquifer
test methods, field quality assurance 1 quality control, and data analysis methodology to be
subscribed to in Task 4. Record keeping and reporting procedures will also be included in the work
plan. This plan must be approved prior to proceeding with Task 4. (No e
Task 4 - Aquifer Testing & Data Analysis - Task 4 consists of determining the
hydraulic conductivity of the aquifer below the landfill by analyzing data obtained from a 24-hour
single well aquifer test performed in monitoring well B-413.
A single well pump test will be performed on one of the site wells. A single well pump test was
selected because of the limited number of wells on site and the large distances between wells.
Attachment A-4
---------------------
Attachment A - Scope of Work
Although a single well pump test cannot be used to determine aquifer storativity,the results can be
used to calculate the hydraulic conductivity that will be used in the contaminant transport modeling.
The pump test will be performed by lowering a submersible electric pump into the well along with
a transducer connected to a data logger. Groundwater will be pumped at a rate high enough to
demonstrate drawdown in the well but not so high that the water level will drop below the pump(the
pump rate is identified to be about 5 to 10 gallons per minute). The pump test is expected to run
continuously for 24 hours and during the test,a geologist will periodically observe the data stored
on the data logger to ensure that the pump test data is useable and consistent.
Purged groundwater generated during the pump test will be placed in a 21,000 gallon Baker Tank
for storage pending chemical analysis to determine whether or not the purged water be disposed of
at the wastewater treatment plant. It is proposed that the City retrieve a grab sample and have it
analyzed by their contract laboratory,Lee&Ro,for Appendix I VOCs(EPA Method 8260),and that
the City be responsible for the disposal of the purged groundwater. Based on the extremely low
levels of VOC contamination which might occur, it is proposed that the City remove the tank
contents using the City's Vactor truck,and discharge the purged water into the wastewater treatment
plant's influent stream in accordance with the plant's permit conditions.
The pump test data will be downloaded and calculations will be performed to determine the
hydraulic conductivity of the aquifer materials. The results obtained will be used in the Fate and
Transport Modeling effort. ages eeept Idling)
Task 5 - Landfill Gas and Groundwater Data Analysis - Task 5 consists of
accessing and analyzing trends of landfill gas constituents which may be related to groundwater
chemistry trends. This analysis will determine if there is any real-time correlation between
groundwater chemistry and landfill gas migration,and support a conclusion for landfill gas impacts
to the groundwater rather than a liquid release. This approach and analysis has been performed in
the past and successfully demonstrated as such to the SARWQCB. The analysis will result in a
combined landfill gas and groundwater chemistry database,with supporting graphical representation
of the data in Excel format. These materials will be presented during Task 7 and will included as
support documentation in the
PO*O#*As0cs*n ,�_d (Task 8).
Task 6 - Contaminant Transport Analysis-Task 6 consists of estimating the potential
longitudinal dispersion of contaminants released from the landfill. This will be done by performing
a two-stage fate and transport analysis. First, leakage from the landfill will be utilized from the
previous United States Army Corps of Engineers HELP3 (Hydrologic Evaluation of Landfill
Performatice) computer analysis of the landfill, conducted in April of 1998. HELP3 uses
representative rainfall and evapo-transpiration data to determine the quantity of leachate and rate of
leakage that might be anticipated from a municipal solid waste-1 dfill. Second,relevant source and
Attachment A-5
Attachment A - Scope of Work
hydraulic parameters will be used as input for the program MULTIMED, to estimate the
concentration of chemical contaminants at progressively larger distances from the landfill.
The Environmental Protection Agency's Multimedia Exposure Assessment Model (MULTIMED)
for exposure assessment simulates the movement of contaminants leaching from a landfill in both
the unsaturated and saturated zones. A steady-state, one-dimensional, semi-analytical module
simulates flow in the unsaturated zone. The output from this module,water saturation as a function
of depth, is used as input to the unsaturated zone transport module. The latter simulates transient,
one-dimensional(vertical)transport in the unsaturated zone and includes the effects of longitudinal
dispersion, linear adsorption, and first-order decay. The unsaturated zone transport module
calculates steady-state contaminant concentrations. Output from both unsaturated zone modules is
used to couple the unsaturated zone transport module with the steady-state saturated zone transport
module. The latter includes one-dimensional uniform flow, three-dimensional dispersion, linear
adsorption, first-order decay,and dilution due to direct infiltration into groundwater. (No changes,
except scheduling)
Task 7 - SARWQCB Presentation - Task 7 consists of providing one informal meeting
and presentation of the demonstration report results to the SARWQCB.
Task 8 - Demonstration Report (DR), Release Delineation Assessment
Report (RDAR), contingency Evaluation Monitoring (EMP) and Corrective
Action (CAP) Plans -Task 8 consists of two reports,a Demonstration Report,and a Release
Assessment Delineation Report. The reporting services will include technical writing and drafting
as necessary to present the findings of Tasks 1-7,and Tasks 14-12 into a responsible demonstration
that sources other than the landfill are likely responsible for groundwater contamination in the
vicinity ofthe CSL,and an assessment that groundwater quality impacted by these sources precludes
the feasibility of off-site groundwater monitoring under an EMF for the CSL. Additionally. the
reports will present data collection and modeling results demonstrating that the low levels of
contamination identified at the landfill do not present a threat to the environment or to health and
safety. This task will also provide the City with responses to comments on the reports on an as--
needed basis during the regulatory review and approval processes.
Task 9 - JTD Amendment #2 (Contingency) - Task 9 consists of submitting an
amendment to the Joint Technical Document (JTD) summarizing any proposed changes in
operations, design. or monitoring which may result from approval of elements in the Delineation
Assessment report. This task will be accomplished by revising or adding to selected text, figures,
and tables in the current JTD, and updating the JTD Indices.
Attachment A-6
Attachment A - Scope of Work
Task 70 - Crafton-Redlands & !'Norton Plumes Review - Task 10 consists of
performing technical review of the published information available on the Crafton-Redlands and
Norton groundwater contamination plumes. This review will focus on the potential relationship
between these investigations(to-date),and the contamination found in the groundwater at the CSL
boundary. The review will also identify any QAIQC problems, data gaps, and future phases and
schedules planned for these investigations. The results ofthe review will be submitted as part of the
Demonstration Report(Task 8).
Task 7 7 - Hydrogeologic Analysis - Task l 1 consists of performing a hydrogeologic
analysis combining the hydrogeologic data from the Crafton-Redlands and Norton groundwater
plumes investigations, other published water well and monitoring well data in the vicinity of the
CSL,and the hydrogeologic data collection and modeling performed in Tasks 4 and 5. The analysis
will include findings resulting from an investigation into the laboratory QA/QC procedures
documented for these data. The purpose of the analysis is to define the nature and extent of
groundwater contamination attributable to the CSL using modeling scenarios, and to further
demonstrate that the groundwater surrounding the CSL is currently contaminated by sources other
than the landfill. The known extent and degree of this contamination is severe enough to over-ride
the impacts from the contamination found at the landfill boundaries,and presents an unsupportable
fuiancial and legal burden upon the City,should they be required to monitor groundwater off-site,
within the vicinity of the plume. The analysis will be conducted in two phases;a preliminary phase
which will generate information suitable for the Demonstration Report, and a detailed analysis,
which will generate findings for the Release Delineation Assessment Report(Task 8).
Task 72 -Review, Analysis and Upgrade of Laboratory QA/QC Procedures
-Task 12 consists of conducting a comprehensive review and field investigation of the laboratory
procedures of Lee&Ro,the laboratory which generated the CSL groundwater analytical data during
the fourth quarter of 1998 and first quarter of 1999. It is believed from a review of the laboratory
QA/QC data reported, that there is evidence for cross-contamination of groundwater samples
resulting from laboratory practices used for storing supplies and cleaning equipment. It is also
believed that it can be demonstrated that there is no feasible method for eliminating the low levels
of cross-contamination found at current laboratory method detection limits. This investigation will.
include blind duplicate and spike samples to be collected and analyzed by separate laboratories,as
well as inspections of,and interview with, the laboratories conducting the analyses.
An investigation into field practices will also be conducted.which will include accompanying City
staff on the COC scan sampling round.and conveyance of duplicate trip blanks sealed in separate
ice chests prior to transport from each laboratory, as well as the regular trip blanks. This
investigation, and its findings. will be included as part of the Demonstration Report (Task 8).
Attachment A-7
Attachment A - Scope of Work
Deliverables - Deliverables will consist of memorandums, text, and faxed information to be
provided to City staff on a time and materials basis upon request. Five tabularized printouts of the
economic analyses results will be provided to the City, along with a short narrative in memo form,
summarizing the updated information used in the evaluations.
A work plan detailing the proposed pump test procedures and a description of the modeling to be
conducted, will be prepared and submitted to the RWQCB for approval prior to proceeding with
field activities. One copy of the draft work plan and five copies of the final work plan will be
provided to the City.
Meeting and presentation materials will consist of a presentation agenda, and all text and graphical
representations of the data analyzed in the form of hand-outs, which will be discussed during the
meeting. As many copies of these materials will be provided as necessary and/or requested by the
City and the SARWQCB.
One complete draft copy each of the Demonstration and Delineation Release reports will be
submitted to the City for review. After incorporation of the City's comments, eight bound copies,
one unbound reproducible copy, and one copy of the final reports in electronic format will be
submitted to the City. The delineation report will contain all pump test data, pump test hydraulic
conductivity calculations. test results, and calculations. The reports will include detailed excerpts
from published reports on the Crafton-Redlands and Norton groundwater plumes, as well as
supporting waterwell datawhich support and illustrate the degradation ofdowngradient groundwater
quality attributable to sources other than the CSL. The report will also include the results of the
MULTIIVIED Fate and Transport modeling with figures showing contaminant concentration
gradients,flow directions,and chemical attenuation,to demonstrate any the nature and extent ofany
impacts to the environment and human health and safety related to the low concentrations of Vocs
identified at the CSI. boundary.
