Subsurface Investigation Work Plan – Work Element 2
Twin Cities Assembly Plant 966 South Mississippi River Boulevard St. Paul, Minnesota
1. Introduction
On behalf of Ford Motor Company (Ford), ARCADIS has prepared this Subsurface
Investigation Work Plan – Work Element 2 (Work Plan) for the Twin Cities Assembly
Plant (TCAP; Site) in accordance with the requirements of the Minnesota Pollution
Control Agency (MPCA) Voluntary Investigation and Cleanup (VIC) Program and
Petroleum Brownfields Program (PBP). The property location and layout are depicted
on Figure 1.
This Work Plan describes Work Element 2 of subsurface investigation activities with
the purpose of evaluating impacts identified during the completion of the Subsurface
Investigation - Work Element 1 (WE1). The scope of work consists of the completion of
soil borings, installation of temporary monitoring wells, and soil and groundwater
sampling within 6 of 11 Focus Areas (FA) (Figure 2). Investigation activities will be
implemented and completed within each individual FA as they become available
following ongoing Site demolition activities.
1.1 Property Location and Description
The Site is located at 966 South Mississippi River Boulevard in St. Paul, Ramsey
County, Minnesota at approximate Latitude (north) 44o 54’ 50.8” and Longitude (west)
93o 11’ 31.9”. The Site is located in a mixed industrial, commercial and residential use
area on the eastern shore of the Mississippi River, along the east side of South
Mississippi River Boulevard, south of Ford Parkway and west of South Cleveland
Avenue (Figure 1).
Operations at the Site formerly consisted of the assembly and painting of light duty
trucks (Ford Ranger) using parts manufactured off-Site. Assembly processes included
welding, metal cleaning, painting and curing, windshield and trim installation and
preparation of the vehicles for final delivery. In addition, a wastewater treatment plant
and steam plant operated at the Site and was associated with the former assembly
operations. Manufacturing operations at the Site ceased on December 16, 2011 and
demolition activities commenced on June 10, 2013.

2. Field Methodology
This section provides a summary of the means and methods to be utilized during this
subsurface investigation. Field logbook/documentation procedures and the field quality
assurance program will be implemented in accordance with the approved June 2007
Field Sampling Plan (FSP) (ARCADIS 2007) and its amdendment (ARCADIS 2013).
2.1 Utility Clearance
A full utility clearance will be performed prior to initiating any subsurface work at the
Site. Activities will include at a minimum:
Notification of Gopher One Call for marking of all public utility lines servicing the
Site,
Location of private utilities in the areas identified for subsurface work, and
Surficial inspection using available utility and historic operational maps for each
proposed boring location.
After removing any surficial debris (i.e., asphalt or concrete), a hand auger will be used
to: 1) confirm the presence/absence of utilities and 2) investigate the top five feet bgs if
no utilities exist. When hand augering will not be possible due to subsurface
material/utilities a hydro-vacuum unit will be used to clear the area. Note that this will
not allow ARCADIS to collect soil samples for analytical testing if the hydro-vacuum
unit is utilized.
2.2 Groundwater Investigation
Groundwater elevation and potential impacts will be determined through the installation
and sampling of temporary monitoring wells in defined areas within select FAs.
Temporary wells will be installed in select boreholes (presented in Table 1) to
determine potential groundwater impacts within the upper water-bearing unit.
Temporary wells will be constructed of 1-inch diameter, 5-foot-long polyvinyl chloride
(PVC) slotted well screens and associated PVC riser. The temporary wells will be
purged of at least one gallon of groundwater using a peristaltic pump and disposable
tubing prior to sampling to minimize turbidity. At least one groundwater water sample
will be collected from the shallowest groundwater encountered at each location.
Groundwater samples collected from temporary monitoring wells will be analyzed for
one or more of the following analytes:
3
Subsurface Investigation Work Plan – Work Element 2
Twin Cities Assembly Plant 966 South Mississippi River Boulevard St. Paul, Minnesota
Volatile organic compounds (VOCs) using USEPA Method 8260,
Semi-volatile organic compounds (SVOCs) using USEPA Method 8270,
Gasoline range organics (GRO) and diesel range organics (DRO) using the WI
Modified Method,
Dissolved Target Analyte List (TAL) Metals and Lead using USEPA Method
6010, and
Cyanide using USEPA Method 335.4.
All samples analyzed for metals will be field filtered using a 0.45-micron disposable
filter prior to sample collection. A summary of the proposed temporary monitoring well
locations and analytical parameters is presented in Table 1.
2.3 Soil Investigation
Soil borings will be advanced using direct push technology in areas of known impacts.
Each boring will be logged continuously by an ARCADIS field geologist and screened
using a Photoionization Detector (PID) with an 11.7 electron volt (eV) lamp that has
been calibrated at least twice a day. Soil boring logs will be created in the field and
identify material encountered for each borehole to total depth using the United Soil
Classification System (USCS). Upon completion, bentonite chips will be used to
abandon each borehole if the borehole is unregulated. If the borehole is classified as a
“regulated hole” according to Minnesota Department of Health (MDH) guidelines, the
borehole will be sealed in accordance with MDH Guidelines and a Borehole Sealing
Record will be prepared.
A minimum of one and up to four soil samples will be collected at each borehole. At
proposed delineation locations, one soil sample will be collected from the interval
depicting the highest PID reading or potential impacts through visual or olfactory
observations. Although this interval is anticipated to correspond with exceedances
observed at the original borehole location, additional soil samples may be collected
from intervals corresponding to initially observed exceedances or intervals below the
observed exceedance to provide vertical delineation.
Soil samples will be collected in laboratory supplied containers and placed on ice
pending shipment to the laboratory. Following standard chain-of-custody procedures,
all samples will be submitted to a designated laboratory for analysis of one or more of
the following analytes:

VOCs using USEPA Method 8260,
SVOCs using USEPA Method 8270,
GRO and DRO using the WI Modified Method,
TAL metals using USEPA Method 6010,
Cyanide using USEPA Method 335.4.
Anticipated boring depths and laboratory analysis parameters for each boring location
is presented in Tables 1.
2.4 Investigation-Derived Waste
Investigation-Derived Waste (IDW) generated during the course of the subsurface
investigation will include soil cuttings (i.e., from hand clearing, hydro-vacuum, and
drilling), purge water, personal protective equipment (PPE) and disposable sampling
equipment (i.e. filters, tubing, PVC).
Soil cuttings will be segregated in the field prior to disposal pursuant to field
screening results; segregation parameters will be of 0 parts per million (ppm)
to <100 ppm and greater than 100 ppm. One composite sample will be
collected for laboratory analysis from each staging area for every five 55 gallon
drums generated. Laboratory analysis will be utilized for the determination of
potential site re-use or offsite disposal.
Purge water generated during groundwater monitoring activities will be drummed
for off-site disposal after review of laboratory analysis.
PPE and disposal sampling equipment will be segregated and disposed of upon
review of subsurface investigation results.
2.5 Surveying
All borings and monitoring wells will be surveyed for X, Y and Z (ground surface)
coordinates referencing the National Geodetic Vertical Datum of 1929 (NGVD 29) and
North American Datum of 1983 (NAD 83) at the completion of subsurface investigation
activities.

3. Scope of Work
With consideration of former Site operations, construction, geographical layout, and
environmental activities completed to-date, the Site has been divided into 11 FAs as
depicted on Figure 2. Furthermore, the FAs have been divided into two groups (A and
B) with geographic consideration. Group A includes FA-01 through -07 and FA-09,
located east of Mississippi River Boulevard, and Group B includes FA-10 and FA-11
located west of Mississippi River Boulevard.
The total number of borings, depth, and analytical sampling requirements were
developed based on analytical results from previous investigations completed at the
Site. The investigation activities associated with this Workplan will be conducted
concurrently with remaining WE1 investigation activities. The results from WE1 were
utilized to determine the need of additional groundwater delineation, where collection of
the sample is contingent upon encountering water in the borehole. Detailed sampling
and analysis information is presented in Table 1 and presented on Figures 3 through 8.
3.1 Group A
Group A includes FA-01 through FA-09, with the exception of FA-08 (baseball fields).
Investigation results for FA-08 was addressed in 2008 and reported in the Response
Action Implementation Report – Baseball Fields – Feature 139 (ARCADIS 2008).
Investigation activities within Group A FAs will include:
Delineation of exceedances of residential Soil Reference Values (SRVs) in soil,
and
Delineation of exceedances of MDH HRLs and the USEPA Arsenic MCL in
groundwater through the installation and sampling of temporary wells.
3.2 Group B
Group B consists of FA-10 and FA-11, but only includes investigation at FA-11.
Investigation results for FA-10 were reported under separate cover to the MPCA in the
April 2014 Area C –Comprehensive Site History and Investigation Report (ARCADIS
2014). Investigation activities within Group B will include:
Delineation of exceedances of recreational SRVs in soil, and
Delineation of exceedances of MDH HRLs in groundwater through the
installation and sampling of temporary wells.
