Item
Approval of an amendment to the original agreement for engineering services for
addressing the groundwater/soil contamination in the central part of Salina.
Background
The original Master Services Agreement with Camp Dresser & McKee {CDM), dated May
23, 1994 outlined tasks to be performed to assist us resolve certain contamination
issues in the central part of Salina. Engineering services provided by CDM in
Phase I of the Master Service Agreement, assisted us in the drafting of the
Consent Order and Settlement Agreement with the Kansas Department of Health and
Environment {KDHE}.
Phase II as identified in the Master Service Agreement will be separated into five
(5} separate major tasks:
Task 1: Develop Project Planning Documents
Task 2: Conduct Site Investigations
Task 3: Prepare Final Feasibility Study
Task 4: Investigation Reports
Task 5: Complete Engineering Evaluations and Design
Remedial Action Oversite
At the October 24, 1994 City Commission meeting, the Mayor was authorized to sign
the KDHE Consent Order and Settlement Agreement. This document outlined a scope of
work for remedial investigation and a feasibility study addressing the
contamination issues.
CDM has now submitted an amendment to their Master Services Agreement to
accomplish the next phase of work as specified in the KDHE Consent Order. In
summary, this work identified as Task 1, Phase II includes:
{a) Data Review and Collection

Recommendation
We have reviewed Amendment No. I as submitted by Camp Dresser & McKee to provide
the Task 1, Phase II services for addressing the issues involved in the
remediation of groundwater and soil contamination in the central part of
Salina. We believe this agreement will allow the City to continue in a pro-active
leadership role in this matter. Compensation for services provided by CDM to
perform the scope of work described in the attached agreement will be on the
following basis:
1. Actual labor costs times an overhead factor of 3.1
2. Actual costs for out-of-pocket expenses (i.e. travel, lodging, meals,
telephone, etc.)
It is our recommendation, therefore, the City Commission approve the attached
Amendment No. I as submitted by Camp Dresser & McKee in an amount not to exceed
$75,576.

1. Scope of Services - Phase II
Task I - Develop Project Planning Documents
T0zk 1-1: Data Review and Collection
In order to facilitate assessment of potential interim actions using PWS wells and to prepare the work
plan requested by KDHE, the following data will be collected and reviewed:
Historic and current water levels in PWS wells
Historic and current water levels in private wells and monitoring, wells across the site
Pumping records for PWS wells including average pumping rates and periods of operation
Identification of all other pumping wells in the area along with their pumping rates and
periods of operation
Identification of all phase 1, 2, or 3 environmental audits in the vicinity of the site
AIl available information on the Old and New Smoky River Channels including flow with
seasons and other surface water features in the area
Any data in the KDHE and EPA files
In addition, historic aerial photos will be obtained and reviewed to help with source identification and
general site history development. All pertinent chemical data collected will be entered into a
computerized data base. Based on the data collected, a conceptual model of the site will be developed
and a preliminary assessment of alternative actions and cleanup goals will be initiated.
Task l-la: Pumping Test [Optional]
In addition to the above available data, the ENGINEER will collect the following new information (if
necessary, based on review of available information):
One pumping test will be conducted to determine aquifer characteristics.
The pumping test will be performed at an existing PWS well in the vicinty of the Site. Two
piezometers will be installed to monitor water level response. The subject PWS will have to be shut
down for a week prior to the test. The well would then be turned on for 72 hours during the test and
then shut down again for a minimum of 48 hours to monitor the aquifer recovery.

Task 1-2; Development of Site Conceptual and Numerical Models
Based on the data collected during Task 1-1, the following evaluations will be performed by
ENGINEER:
Compilation of a basemap showing well locations, potential source locations, etc.
Generation of geological cross sections showing lithology and water levels
Generation of water level contour maps
Generation of contamination concentration maps
Based on these evaluations, a geological and hydrological site conceptual model will be developed.
The information contained in the site conceptual model will then be translated into a numeric
hydrogeological computer model. Aquifer characteristics from literature resources (or the pumping test
if performed) and measured water levels will be used to calibrate the model. Once the model is
calibrated and shown to represent the site conceptual model, it can be used to determine whether
pumping of the PWS wells can be an effective remedial action.
Task 1-3: Preliminary_ Evaluation of Cleanup Goals. ARARs and Interim Actions
In addition to evaluating the effect of pumping at PWS wells, the potential extent of cleanup will be
developed. In most cases, ground water in aquifers must be restored to drinking water standards.
However, KDHE has recently allowed higher concentrations at the Gilbert-Mosley Site for the
remedial action goal. Selection of the higher goal was based on a risk assessment and use of
institutional controls. In order to guide the work plan and evaluation of potential interim actions, a
preliminary assessment of remedial goals and applicable relevant and/or appropriate requirements
(ARARs) will be conducted. Potential cleanup goals must be known in order to effectively evaluate
appropriate remedial actions.
Once remedial goals and regulatory requirements are determined, potential interim actions can be
assessed. The evaluation will focus on the use of the PWS wells to contain the contaminated ground
water. The evaluations will be conducted consistent with the KDHE statement of work and CERCLA
guidance. That is, the alternatives will be developed, screened and then evaluated in detail.
Task 1-4: Development of Project Work Plans and Project Plans
As required in the Consent Order and Settlement Agreement, the CITY must submit a Remedial
Investigation/Feasibility Study (RiffS) work plan and associated project plans for KDHE review and
approval. The work plan is a clear and concise statement of activities to be completed to meet the
objectives stated in the Scope of Work attached to the Consent Order and Settlement Agreement. The
results of tasks 1-1, 1-2 and 1-3 outlined above will be incorporated into the work plan and used to
streamline and focus the proposed Riffs activities.

Specifically, the work plan will include:
Site Characterization and Conceptual Model
Preliminary Evaluation of Cleanup Goals and ARARs
Evaluation of Interim Remedial Actions
Proposed Remedial Investigations
A Description of the Feasibility Study
Schedule and List of Deliverables
The remedial investigations activities (field collection of data to characterize the contamination extent)
will be limited to only that data necessary to support selection and design of remedial alternatives.
In addition to the work plan, the following project plans must be prepared as required by the Consent
Order and Settlement Agreement:
Site Health and Safety Plan: This plan discusses the known and suspected wastes at the site.
Individual aspects of the field investigation are evaluated with the level of protection necessary
for each activity. Protective equipment, monitoring equipment and decontamination
procedures are identified.
Field Sampling Plan. The FSP includes a detailed description of all sampling and analyses to
be performed during the RI. Included will be field collection procedures, shipment of samples,
documentation of sampling, quality control and laboratory analyses.
Quality Assurance Project Plan. The QAPP includes all aspects of quality control and
assurance for the project. Quality control procedures for sampling, sample documentation,
chain of custody, and laboratory analyses are discussed in detail.
Community Relations Plan. The CRP will outline the task to be completed to keep the public
informed of the progress of the project. This will include fact sheets, public meetings and new
releases. The CRP must include interviews with selected citizens to document their concerns.
The CRP must be completed before field work can commence.
Task 1-5: Meeting and Pro_iect Management
Once the Work Plan and Project Plans are complete, they will be submitted by the ENGINEER to the
CITY for review. The ENGINEER will meet with City Personnel to review and incorporate
comments. The Work Plan and Project Plans will be revised and submitted to KDHE for review. The
ENGINEER will meet with KDHE to discuss comments. Final Work Plan and Projects will than be
submitted to KDHE. The Draft Work Plans and Project Plans will be submitted to KDHE within 150
days after signature of the Consent Order and Settlement Agreement.
