Attn: Mr, Mike Sweeney- Owner's Representative
RE: SCOPE AND BUDGET PROPOSAL
SOIL EXCAVATION AND SOIL iNVESTIGATION ACTIVITIES
FOSTER GOLF LINKS PROJECT
PARKS AND RECREATION DEPARTMENT
Dear Mr. Sweeney:
Landau Associates is pleased to submit this proposed scope of services and c~st estimate to
conduct soil excavation and subsurface investigation activities for the Foster Golf Links faaility (subject
property) in Tukwila, Washington. The area to be investigated and excavated is near the noz~hwestem
comer of the new lower parking lot located west of the main clubhouse at the subject property.
SCOPE OF SERVICES
Based on our discussions with you and our observations at the site, we understand that you would
like Landau Atsoclates to conduct the following tasks at thc subj~c! property:
· Task 1 - Initial excavation of petroleum impacted soil associated with a former
underground storage tank(LIST) system. This ~ask was completed as of April 30, 2004,
· Task 2 - Subsurface investigation to assess the extent of pe~xolcum impacted soil emanating
from the former UST system and to evaluate if groundwater appears to be impacted by
pe~'oleum constituents.
· Task 3 - Additional excavaiion of petroleum impacted soll based on the results from thc
subsurface investigation completed as Task 2.
· Task 4 - Preparation af documentation to noii~y the Washington State Department of
Ecology (Ecology) of the petroleum impacts observed, to summarize the activities compleled
for Tasks 1 through 3, and to make recommendations for additional actions, if necessary,
· Further description of the tasks identified ~bove are included in hhe following sections;
Task 1 - Initial Excavation of Petroleum Impacted Soil
Landau Associates and Cecon Corporation (Cecon) completed this task at your request based on
an authorization you provided in an e-mail dated April 26, 2004. The authorized scope of work for this
task originally included thc removal of approximately 30 tons of petroleum impacted soil and the
r~placement of thc excavated soil with "clean" backfill. However, based on observed site conditions and
with yoor verbal authorization, approximately 175 tons of petroleum impacted were removed from
site on April 29 and 30, 2004 and approximately 130 tons of clean fill were imported and stockpiled on
site. The soils excavated were transported to TPS Technologies, Inc. (TPS) in Tacoma, Washington for
thermal desorpdon treatment and disposal. As discussed with you on April 30. 2004, it appeared that
significant additional petroleum impacted soil was present beyond the limits of thc excavation to the
north, south, cast, and west, On May 3, 2004, it was agreed that a subsurface assessment should be
completed beyond the limits of the excavation area to determine the appropriate limits of the excavation
and to determine if some of the petroleum impacted sell could remain in place based on appropfiaxe soil
cleanup levels as published in the Washington State Model Toxics Control Act (IvrrcA), The original
budget agreed on for this task was $9,432, Based on the additional soil removed and imported, the actual
cost to complete Task I will be approximately $14,000.
Task 2 - Subsurface Investigation
On May 6, 2004, Landau Associatc~ personnel will return to the subject site ,with a drilling
subcontractor to conduct a subsurface investigation on the p~iphery of the excavation completed on April
29 and 30, 2004. The purpose of ibc subsurface investigation will b~ to at'tempt to dcm'mine the extent of
petroleum impacted soil in the vicinity of thc former UST system and to attempt to determine if thc
groundwater appears to be impacted, Direct push ~rilling methods will be used to collect multiple soil
sampl~ and one groundwater sample in the vicinity of the excavation area, We expect to complete up to
10 soil borings to a total depth of 15 ft or less during the completion of Task 2. During thc completion of
the soil borings, a Landau Associates geologist will visually inspect the soil recovered from the borings
and use a photo ionization detector (PID) to "screen" soils in an attempt to determine the relativn levels of
petroleum impact. The Landau Associates field geologist will collect representative soil samples from the
soil borings to submit to an analytical laboratop/for analysis of petroleum impacts. The soil samples will
be analyzed by the laborato~ff for gasoline range total petroleum hydrocarbons (TPH-Ox) using Method
NW'TPH-Ox; benzene, toluene, ethylber~.enc, and xylenes (BTEX) using EPA Method 8021; and total
lead using EPA Method 6010/"/470. Sample results will be requested from thc analytical laboratory on a
7-day turnaround time (TAT). In addition to the soil samples, the field geologist will collect one
groundwater sample from the soil boring which exhibits the highest level of petroleum impact. The
groundwater sample will also 1:~ analyzed for TPH-Gx, BTEX, and total lead using the same methods
identified above. The estimated cost to complete Task 2 is $5,750, which includes approximately $3,200
in subcontractor fees for drilling and laboratory analysis.
Task 3 - Additional Excavation of Petroleum Impacted Soil
Following the completion of the subsurface investigation activities outlined in Task 2 and
i~terpretation of the analytical resultS, Landau ^ssociates will return to the subject site with Cecon to
remove additional petroleum impacted soil for offsite disposal at TPS. Landau Associates pcrannncl will
utilize the information gathered during the completion of Task 2 to id~tify the approximate lateral extent
of the excavation area. Landau Associates will use observations made during the completion of Tasks I
and 2 and field monitoring equipment to attempt to segregate "clean" overburden soil from the petroleum
impacted soil to be disposed off site at TPS. Landau Associates will collect soil samples for laboratory
analysis to document soil conditions at the limits of the excavation. The estimated cost to complete Task
2 is approximately $21,000. Approximately $16,500 of the Task 2 cost will be for subcontractor fees
associated with s~il excavation, transporl, disposal, analysis, and backfill operations. This cost estimate
to complete Task 2 is based on thc following assumptions:
· The excavation work will be conducted to remove petroleum impacted soil in excess of
appropriate MTCA Method A (unrestricted land use) cleanup levels,
· The soil ~xcavation, loading, and site ~estoration will require a total of 3. 10=hour days onsite
for Landau Associates and Cecon personnel.
· A total of 180 tons of petroleum impacted soil will be removed, for offsite disposal at TPS.
· A total of up to I0 soil samples will be collected from the extent of the expanded excavation
and the soil stockpile, as appropriate. The soil samples will be analyzed for TPH-Gx using
Method NWTPH-Gx; BTEX using EPA Method 8021; and total lead using EPA Method
6010/7470. Sample results ~ll be requested from the analytical laboratory on a 7A-hour
TAT.
· Following the receipt of analytical results, the excavation area will be re-graded and restored
using the "clean" soil excavated from the subject site and imported backfill. For the purpose
of this cost estimate, approximately 100 tons of imported of backfill is assumed to be
required. ~
Task 4 - Preparatlun of Documentation
Landau Associates will review the analytical data generated during the field activities and present
the data along with a summary of the work in a repor~ to document the UST and soil removal tasks. Thc
documents prepared by Landau Associates will include a notification to Ecology to report the
observations indicating a release of gasoline to thc subsurface has occurred at tho subject property and a '
summary repot/to detail the activities completed to investigate the axtcnt of the petroleum impacts, the
actions completed to address the petroleu,m impactS, and recommendations for additional action, if
nace. ssa~/. The estimated budget .for Task 4 ts approximately $5,500,
EgTIMATP, D SCHEDULe.
We are prepared to initiate thc work described in this proposal upon receipt of your authorization
to proceed, We anticipat° the c°mpletiun °f Task 2 by May 10, 2004; Task 3 by May 20' 200'~; and Task
4 by May, 31, 2004.
· The depth to groundwater at thc subject property is approximately 15 to 20 fl Boa and we
will be able to advanca a direct push sample probe to groundwater for the collection of a
sample.
· Thc handling charge for subcontractor costs is 12 percent.
· Costs do not include a continge~tey amount for unanticipated out-of-scope activities by
subcontractors and/or Landau Associatcs. If unanticipated out-of-scope activities am
necessary, Landau Associates personnel will advise you of the situation and proceed upon
receiving your authorization. Out of scope activities will be charged in accordance with the
rate schedule and general conditions included as Attachment A to this proposal.
L~qDAU AsSOCIATI~S
· MTCA Method A cleanup levels will be used to assess whether soil or groundwater has been
impacted and requires additional action. However. if application of the MTCA Method A
cleanup levels would result in the disruption of operations at thc subject site, we will discuss
with you and an E¢olo~ representative the potential use of more lenient cleanup levels that
may require restrictions on future site uses.
