SUBJECf: PROPOSAL TO PERFoRM A SUBSURFACE INvEsTIGATION AT 1097 B STREET IN AsHLAND,
OREGON (ODEQ USTC FILE '15-00-0024)
Dear Mr. Smeenk:
As per your request, Cascade Earth Sciences (CFS) prepared a proposal and cost estimate for further
characterization of potential soil and groundwater impacts at 1097 B Street in Ashland, Oregon (Site)
August 3, 2006. CFS was originally asked to provide a proposal for the Site in January 2004. The 2004
proposal was based on a conference call on January 23, 2004, with Eric Oough at the Oregon Deparbnent
of Environmental Quality (ODEQ) Tanks. Program. Since the original proposal, regulations have
changed and ~sions with. Oaudia Johansen and Joe Klemz at (ODEQ) have indicated a new
analytical suite will be required, due to these changes. This proposal has been updated to reflect costs
using 2007 CFS rates (attached).
Our goal is to assist the Oty of Ashland (City) in closing the Site with a 'No Further Action' letter from
ODEQ. In order to do this as efficiently as possible, this proposal has been broken into several tasks. As
we discussed, what is learned in the first task (review of the Site information and development of an
action plan) will affect which of the ensuing tasks (if any) will likely need to be performed to achieve Site
closure. For example, based on what is learned in Task 1 and Task 2, one year of quarterly groundwater
monitoring (Task 3) may not be necessary. Therefore, this proposal pertains specifically to perfonIUng
Task 1. The cost estimates and schedule for the remaining tasks have been included to provide you with
a 'road map' of what the City should plan on if those tasks must be performed.
H you agree with this proposal, and wish to proceed with Task 1, please sign' the authorization section,
and return it to our Albany office. H a PO is issued for this work, please reference pre-project number
2723-750,
We look forward to assisting the City of Ashland with their environmental and engineering needs. If
you have any questions or concerns please contact me at (541) 812-6625 or by cell phone at
(503) 931-3157.
Sincerely,

PROPOSAL TO PERFORM A SUBSURFACE INVESTIGATION
AT 1097 B STREET IN ASHLAND, OREGON (ODEQ USTC FILE
##15-00-0(24)
This Proposal/Work Authorization is intended to establish responsible
parties, ensure communication between Cascade Earth Sciences (CFS)
and the Gty of Ashland (Client), and outline the terms and conditions
under which both parties will operate. The proposal defines the
approach, scope of work, and estimated costs for services provided.
. r
Significant amounts of data already exist for the Site, including
laboratory results for soil and groundwater samples. However, the
data have not been organized or interpreted, making it difficult to
determine how to best proceed. The first step would be to review
and organize the existing Site information in order to develop a
work plan to characterize, and ultimately to close, the Site. Though
the results of the review would dictate the work p~ the Gty
would like to know up-front what the schedule and likely costs
would be to achieve Site closure. Therefore, based on what CFS has
learned. to date, tasks that may be necessary to achieve closure of the
Site are presented in this proposal to assist the Gty in their planning
process.
The Site is currently the Gty of Ashland (City) maintenance shop,
which has been used over the years for maintenance and repair of
equipment and vehicles. Reportedly, the Site may have been used as
an aboveground bulk fuel storage site. Along with the recent
conference call, CFS also met with the Oregon Department of
Environmental Quality (ODEQ) on April 10, 2001, to discuss the
project and to come to agreement on the next steps, with the
ultimate goal of receiving a No Further Action (NF A) letter from the
ODEQ.
From the information provided by the Gty, and information I
gathered from the ODEQ project files, it appears as if three
underground storage tanks (USI's) were decommissioned in place at
the site on April 29, 1988. Two of the USI's contained gasoline and
were each 1,000 gallons in volume; the other usr contained diesel
fuel and was 2,500 gallons in volume. At the time of
decommissioning, the diesel fuel UST was approximately 10 years
old, and the gasoline USI's were approximately 30 years old. During
the development of a new shop facility on May 3,2000, Gty
contractor's encountered petroleum impacted soil, which appeared

to originate from the decommissioned USTs. The Oty contracted
. with Pump~ Pipe, and Tank to excavate the USTs and collect soil
samples. Several test pits and trenches were excavated in the area
. adjacent and downgradient from the former location of the USTs. A
soil sample collected at 3.8 feet below ground surface (bgs), from an
excavation approximately 50 feet downgradient of the USTs,
indiqited the presence of total petroleum hydrocarbon - gasoline
range hydrocarbons (TPH-Gx) at 270 milligrams per kilogram
(mg/kg) and TPH - diesel fuel range hydrocarbons (Ox) at 84
mg/kg. In addition, 75 feet downgradient of the USTs, a soil sample
was collected at 11 feet BGS, near the groundwater/soil interface,
which exhibited a concentration of TPH-Gx at 440 mg/kg and TPH-
Ox at 856 mg/kg. On June 9, 2000, the ODEQ collected soil and
groundwater samples from several excavations at the site. Benzene
was detected at 144 micrograms per liter (J1g/L), in the "North
Trench", which is located approximately 45 feet downgradient of the
former USTs. In addition, two soil samples, at unknown depths,
exhibited concentrations of TPH-Gx at 840 mg/kg and 610 mg/kg,
in trenches 35 feet and 75 feet downgradient of the. former USTs.
Based on the results of the previous investigations at the Site, ODEQ
has asked the Oty for further characterization of potential soil and
groundwater impacts. CFS is re-submitting this new proposal based
on feedback from ODEQ regarding the further characterization.
Specific objectives of the proposed investigation include:
· Review existing information about environmental conditions at
the Site;
· Prepare a work plan to fill data gaps (if any);
· Collect additional soil and/ or groundwa~ data (if any); and
· Prepare a written Risk-Based Evaluation of the Site requesting
closure from ODEQ.

The proposed investigation is presented herein as Tasks 1 through 4.
Each task is outlined below, including 'thetask definition, and
estimated costs.
. Scope of. Work'
Task 1 Site Review and Recommended Work Plan
This task includes project planning and management, meetings,
accounting, and correspondence with the City and the ODEQ.
Continuing the good communicative rapport between the City,
ODEQ, and CFS will be an asset towards ultimate Site closure. CBS
will gather all information the City and ODEQ have regarding the
Site. This will include information such as: digital CAD files of the
Site, any decommissioning reports for the three usrs
decommissioned in 1988, receipts or other information about
contaminated soil excavated and removed from the Site, and
laboratory data. H necessary, CFS may contact Bob McHenry of
Pump Pipe and Tank for clarification. In additio~ CFS will also
perform a site visit.
A draft work plan will be prepared and submitted to the City. The
work plan will present a recommended course of action to fill any
data gaps identified to determine the magnitude and extent of
contamination at the Site so that a risk-based assessment can be
performed (if necessary) to achieve Site closure. The pertinent
existing data will be presented m an organized fashion, including
tables and figures as appropriate. Once the City approves the draft
work p~ CFS will submit it to ODEQ for their review. Comments
from ODEQ will be incorporated into the draft work plan as
appropriate and agreed to by the City. A final work plan will be
prepared for submittal to the City and to ODEQ.
Task 2 Soil and Groundwater Characterization
Based on our initial review of the background informatio~ it
appears that the source of contamination (Usrs and contaminated
soil) has been removed from the Site. Furthermore, the ODEQ has
agreed that the existing suite of compounds analyzed by the
laboratory (l'PH Dx and TPH Gx for many samples, volatile organic
compounds (V0Cs) and ploynuclear aromatic hydrocabons (PARs)
for some samples) is adequate. Therefore, additional soil
characterization should be limited.

Results for groundwater are based on one sample collected frOin pit
water during excavation activities. The'reported concentrations are
higher than several of the risk-basecI guidelines. Additional
groundwater assessment and sampling will likely be needed to
characterize the magnitude and extent of the groundwater impacts..
. A GeoProbeN will be used to advance four soil borings at areas
requiring further delineation. Actua1locations will be made based
on what is learned in Task 1. The borings will be continuously
logged for lithology and photo-ionization detector (PID) headspace
readings. A total of four soil samples will be collected from the
borings to be analyzed for petroleum hydrocarbon screening
(NWTPH-HCID). The samples will receive follow-up analysis for
gasoline range hydrocarbons or diesel fuel range hydrocarbons
based on the results of the screening. Additionally, the soil sample
exhibiting the highest concentration of gasoline will receive follow-
up analysis for VOCS and total lead. The sample exhibiting the
highest concentration of diesel fuel will receive follow-up analysis
for VOCS and PAHs. Vertical soil sample locations will be based on
PID readings, odor, and visual signs. All sampling equipment will
be de-contaminated between each sampling event according to CFS
Standard Operating Procedures.
Four 1.S-inch diameter monitoring wells will be'installed at the Site
using the GeoProbeN. The location of the wellS will be determined
in the field, but will likely include one upgradient well, one assumed
'worst-case' well near the area thought to be most impacted, and two
down gradient wells. A licensed monitoring well installer will
install the wells, and start cards will be recorded with the Oregon
Water Resources Department. Lithology will be logged during
drilling, under the direction of an Oregon Registered Geologist The
monitoring well top-of-casing elevations will be surveyed by the
aty.
Wells will be developed by purging at least three well-bore volumes
of groundwater. Purge water will be stored onsite in drums
pending laboratory analysis. Field parameters (pH,
conductivity, and temperature) will'be monitored during purging to
assure that groundwater samples are representative of aquifer
conditions. Wells will be allowed to stand for 24 hours prior to
collection of groundwater samples. Static water levels will be
collected and groundwater flow direction will be eStablished. Wells
will be purged and sampled using a peristaltic pump, and dedicated
tubing to prevent any cross contamination. Groundwater samples
- will be analyzed for NWI'PH-HCID screening, with follow-up
analysis for gasoline and diesel fuel range hydrocarbons. The

sample exhibiting the highest concentration of gasoline will receive
follow-up . analysis for VOCs and disSolved lead. The sample
exhibiting the highest concentration of diesel fuel will receive
follow-up analysis for VOCS and P AHs.
Task 3 Ouarterly Groundwater Monitoring
The four groundwater wells installed in Task 2 will be monitored for
three additional quarters (one full year). Static water levels will be
collected and a figure showing groundwater flow direction will be
prepared. Three well volumes will be purged during each
monitoring event. Samples will be analyzed for the same suite of
analyses as in Task 2. One duplicate sample will be collected and
submitted blind to the laboratory for quality control purposes.
Laboratory results and the figure showing groundwater flow
direction will be submitted to the City and to ODEQ with a brief
cover letter.
Task 4 Risk-Based Closure ReDort
em will prepare a report of findings using the ODEQ's risk-based
decision making guidelines for the remediation of petroleum-
contaminated sites. This will include development of a conceptual
model, identification of appropriate complete exposure pathways,
and an assessment of risk. H the assessment shows that soil and
groundwater at the Site is not impacted greater than any applicable
geneiic risk based concentrations, Site closure will be requested. The
risk-based report will also include a summary of figures, tables,
results from all of the tasks performed earlier.

SOLE SOURCE FINDINGS FOR CASCADE EARTH SCIENCES
A subsurface investigation for the B Street Yard is required by the Oregon Department of
Environmental Quality. The attached requisition is with Cascade Earth Sciences to develop a
detailed work plan to address the scope of the work needed to accomplish acceptance by the
ODEQ that adequate soil remediation has been met. Cascade Earth Sciences were the original
geotechnical investigators during the underground storage tank removal process in 1999 and
already possess data and prior knowledge of the site to complete the work scope efficiently and
economically. At the completion of the work, the produced scope will be utilized to prepare bid
documents to advertise and obtain quotes for any remaining clean up efforts necessary to submit
the ODEQ report for final sign off and issuance of a "no further action" letter.
