known or reasonably ascertainable; and c) that, if the property was used as a permitted hazardous waste
disposal facility, the use of the property or some portion of it may be restricted as provided in Minn.
Stat. § 115B.16, subd. 1 (2016).
2. The City of Chanhassen is the owner of certain real property ("Property") located at
1591 Park Road, Chanhassen, in Carver County, State of Minnesota, and legally described as follows:
Lots 010 and 011, Block 05, of Chanhassen Lakes Business Park
3. The Property was first developed in 1980 by the City of Chanhassen ("City") and used as
a Public Works facility housing public works staff from 1980 until 2012. City operations at the Property
during that time included storage, maintenance and repair of City -owned vehicles and equipment. The
City also installed, operated and subsequently removed several underground storage tanks containing
used motor oil, gasoline and diesel fuel.
In 2012, the City and Interstate Roadrunner, Inc. ("Roadrunner") executed a 5-year Contract for
Deed for the Property. Since 2012, Roadrunner has been operating their vehicle transportation business

Current and historic Property operations are provided in the Phase i Environmental Site
Assessment prepared by Nova Consulting Group, Inc. (Nova) dated July 20, 2016, and the Response to
Comments in Conditional Response Action Plan Approval letter sent by Nova to the MPCA dated
February 15, 2017.
4. A release from one of the installed underground storage tanks was reported to the
MPCA by the City in 1993 and assigned LEAK# 00006914. The release was investigated from 1993
through 1994. In response to the investigation activities, the MPCA issued a Petroleum Tank Release Site
File Closure letter to the City of Chanhassen on December 27, 1994.
In 2016, Roadrunner started the process of obtaining financing to complete the 5-year Contract
for Deed with the City, and take title to the Property. In 2016, Roadrunner retained Nova to conduct a
Phase I ESA and Limited Phase II Environmental Site Assessment to complete lender -required
environmental due diligence. The Phase II identified sub -slab soil vapors at concentrations above the
MPCA's commercial/industrial 33x Intrusion Screening Values. As a result, the Property was enrolled
into the MPCA's Voluntary Brownfields Program, and was assigned Site ID SR0001434.
5. The Phase II ESA conducted by Nova included the advancement of six soil borings,
collection of soil and groundwater samples, and collection of two sub -slab soil vapor samples. The
results of the Phase II did not identify impacts to soil or groundwater above MPCA soil and groundwater
standards. However, sub -slab soil vapor sampling resulted in the detection of trichloroethene ("TCE")
above the MPCA's commercial/industrial Intrusion Screening Values ("ISVs") at a concentration of 54
micrograms per cubic meter (" µg/m3"). Furthermore, Tetrachloroethene ("PCE") was detected above
the MPCA's 33 times ("33x") the commercial/industrial ISV at a concentration of 3,400 µg/m3. In
response, Roadrunner submitted a Response Action Plan ("RAP") to the MPCA on September 14, 2016,
that presented sub -slab soil vapor mitigation system as the remedial action. The MPCA reviewed the
RAP and conditionally approved the RAP, subject to conducting additional investigation activities, and
requesting additional information on City and Roadrunners operations, chemical use, and site history.
In response to the MPCA's request, Roadrunner prepared and submitted a Supplemental Site
Investigation ("SSI") Work Plan, which the MPCA subsequently approved. The SSI included the collection
of three soil samples, advancement and collection of four soil gas samples outside the building, and the
collection of an additional seven sub -slab soil vapor samples from within the building footprint. The soil
samples collected during the SSI did not result in detections of contaminants above MPCA
commercial/industrial soil standards. The Sub -slab soil vapor samples collected during the SSI identified
Benzene, TCE, and PCE, at concentrations above the MCPA's commercial/industrial ISV, however
concentrations did not exceed the MPCA's commercial/industrial 33x ISV action level. Additionally, the
sub -slab soil vapor sampling conducted during the SSI, showed that sub -slab soil vapor impacts above
the 33x ISV were limited to the eastern half of the large maintenance garage area.
Roadrunner prepared RAP Addendum #1 proposing a partial -building sub -slab depressurization
system ("SSDS") as remedy for environmental impacts at the Site and submitted the RAP Addendum to
the MPCA on March 24, 2017. Post Mitigation confirmation samples were collected on June 30, 2017,
with the SSDS operating. Confirmation sampling with the SSDS operating show that sub -slab TCE and
PCE concentrations are 2.4 µg/m3and 56 µg/m3, respectively. Details of the SSDS installation, testing and
sampling are provided in the RAP Implementation report submitted to the MPCA on July 11, 2017.
6. The Phase II ESA and SSI defined the extent and magnitude of soil vapor impacts to the
sub -slab area presented on the figure attached as Exhibit 1. The post -mitigation confirmation sampling
c-rem4-02 • 10126116 2 Doc Type: Institutional Controls
resulted identified that TCE was present in the sub -slab at a concentration of 2.4 µg/m3and PCE was
present at a concentration of 56 µg/m3. Several other VOCs were detected in sub -slab soil vapor;
however none of these other VOCs are at levels above the MPCA's commercial/industrial intrusion
screening values.
7. An Operation, Maintenance and Monitoring Manual ("OM&M Manual") was prepared
to document the proper operation of the SSDS. Additionally, As -built drawings, record -keeping
requirements and contact information for troubleshooting or system repairs are also presented. A copy
of the OM&M Manual is included as Exhibit 2.
8. [Recite any other relevant history of the property, if any, such as whether a certificate of
completion was issued.] None
9. Any person who is planning any use or activity which may adversely affect the
protectiveness of the response action or which has the potential to disturb the response action
equipment described above should contact the Minnesota Pollution Control Agency prior to
commencement of the planned activities.
10. The response actions at the property were approved by the MPCA based on the
assumption that the property was to be used for commercial and industrial uses. If the property use is
changed, the change could associate the property owner with the release or threatened release of
hazardous substances and could result in a requirement for performance of further response actions at
the property.

CONSULTING
1.0 Introduction
Nova Consulting Group, Inc. (Nova) has prepared this Operation Maintenance and Monitoring
Manual to provide operational information and present the maintenance and monitoring
requirements for the Vapor Mitigation System.
The Roadrunner Truck Repair project located at 1591 Park Road in Chanhassen, Minnesota
(the Site) is enrolled in the Minnesota Pollution Control Agency's Voluntary Investigation and
Cleanup Program (MPCA VIC Program). Through investigation activities conducted at the Site,
volatile organic compounds (VOCs) including tetrachloro ethylene (PCE) and trichloroethylene
(TCE) were detected at concentrations above the MPCA's commercial/industrial intrusion
screening values (ISVs) in the eastern half of the storage and maintenance portion of the main
site building. As a result of these ISV exceedances, and as requirement of the MPCA approved
Response Action Plan (RAP) for the Site, a vapor mitigation system (System) was constructed
to address the potential for vapor intrusion into the impacted portion of the building.
2.0 Purpose
The purpose of this document is to outline the operational components of the System, and to
provide protocols for System monitoring, frequency of monitoring, and to provide detail on
how to perform specific maintenance.
3.0 Operation, Maintenance, and Monitoring Protocols
3.1 System Components and Operation
The System consists of six horizontal sub -slab vapor extraction pipes installed in three
shallow trenches excavated below the concrete slab. The six horizontal extraction pipes are
connected via several flow control manifolds to a single RadonAway HS2000 Radon mitigation
fan. Organic vapors, if present, are collected by the System in the extraction trenches and are
actively vented to the atmosphere through the system piping and the vacuum induced by the
fan. Extracted air is discharged above the roof through the discharge stack.
Flow to each of the six extraction pipes can be controlled by a gate valve installed on the south
building wall, at the flow control manifold. Five vapor monitor points (VMPs) have been
installed in the concrete floor to facilitate pressure field extension monitoring and sub -slab
soil vapor samples.
Following system startup, and subsequent diagnostic testing, the System was able to attain the
MPCA-required vacuum level of -5.0 pascals (Pa) across the building mitigation area at a fan
operating point of 70 cubic feet per minute (CFM) at an induced vacuum of 1.6 inches of water
as measured by the summation of flow measurements at the flow control manifolds. The -5.0
Pa requirement was attained with all six gate valves in the fully open position. At this
condition the vacuum levels at each VMP (See Appendix A, Sheet 02) was as follows:

Record drawings of the System construction are provided in Appendix A, and provide details
for the system construction.
Operation and maintenance of the blower shall be completed in accordance with
manufacturer recommendations.
3.2 Second round of Confirmation Sampling
In accordance with the MPCA-approved Response Action Plan, a second round of post -
mitigation confirmation sampling samples should be collected to confirm ongoing system
operation. The second round confirmation sampling should be completed in December 2017
or January 2018, approximately 6-months after System startup. Confirmation sampling shall
include one 24-hour ambient air sample as well as one paired indoor air and sub -slab sample.
The indoor air shall be collected for a duration of 24-hours, and be set near location VMP-3.
Concurrent with the indoor air sample, a grab sub -slab sample shall be collected at VMP-3.
The ambient air, indoor air and sub -slab soil vapor sample shall be submitted to an analytical
laboratory and analyzed for VOCs by EPA Method TO-15. In addition to the air sampling, a
round of system performance monitoring shall be completed. The system performance
monitoring includes collection of vacuum measurements and organic vapor concentrations
with a PID at all five VMPs. Additionally the vacuum, flow rate, and organic vapor
concentrations of each extraction pipe should be collected and recorded. The MPCA's Post -
Mitigation Confirmation Sampling Checklist shall be completed to document the results of the
second round. A summary letter report shall be submitted to the MPCA summarizing the
results of the laboratory analysis, and pressure field extension testing.
3.3 Inspection and Monitoring
On a regular basis, the system shall be inspected to ensure it is operating. This regular
inspection includes observing the installed u-tube manometer to ensure that the fan is
inducing vacuum. Additionally, the vapor monitoring points, vent riser piping, and discharge
stack should be inspected for damage. Any cracked, warped, or missing components shall be
replaced as soon as practical. Replacement components shall match existing components or
be equivalent.
The annual inspection, maintenance, and monitoring activities shall include documenting the
weather conditions, inspecting and verifying the functionality of the fan, noting the vacuum
indicated by the installed u-tube manometer, as well as measuring the velocity, temperature,
and vacuum of each horizontal extraction pipe at the monitoring port, and collecting vacuum
measurements at each vapor monitoring point. This inspection should be performed on an
ROAD RUNNER TRUCK REPAIR NOVA PROJECT NO. W17-0380
PAGE 2 JULY 11, 2017
annual basis initially, and thereafter as practical. The annual inspection activities shall be
documented on the Inspection Form included in Appendix B.
The monitoring port installed in the solid PVC piping that extends above -grade is designed to be
used with a hot wire anemometer to measure the temperature and velocity of the air stream,
and with a Magnehelic differential pressure gauge or digital micromanometer to measure the
vacuum inside the pipe. These devices or similar devices shall be used to measure the velocity,
temperature and vacuum in the vent riser. Additionally, the Cox -Colvin Vapor pins can be
accesses by using a special screwdriver to remove the tamper -resistant cover, for access to
the barbed fitting below. A digital micromanometer capable of measuring down to 1 Pa
shall be used to monitor vacuum conditions at each VMP.
3.4 Troubleshooting
Vacuum levels below -5.0 Pa at the VMPs or less than 1.5" of water when read from the u-tube
manometer are indications that the System may not be functioning properly. Following system
measurements that indicate vacuum delinquency, the fan should be checked for proper
operation, system valves should be checked to ensure they are open, and the system piping
should be inspected for blockage. If the f an is not operating properly, it should be replaced or
repaired. A replacement fan shall be procured that meets the specifications listed in Appendix
C. If blockage is identified, it should be cleared. Follow-up monitoring for vacuum should
commence once the system is repaired.
If vacuum delinquency is only observed in one or more VMP, the system valves can be
manipulated to redirect flow from one section of horizontal extraction piping to another. This
process can be a trial and error process, so accurate documentation of valve position, and
associated flow and vacuum levels in each horizontal extraction pipe should be noted during
each valve adjustment. Valve adjustments should be made until a minimum -5.0 Pa is attained
at each VMP. Following this re -balancing exercise, the valve position, flow rate, and vacuum
level for each horizontal pipe should be documented, and filed for possible future reference.

3.6 Records Management
As a requirement of the MPCA approved RAP for this site, on file with the MPCA VIC Program,
and the recorded Affidavit of Real Property Contaminated with Hazardous Substances, the
System must remain operational at all times. As such, this Operation, Maintenance &
Monitoring Plan and completed copies of the Inspection Forms shall be maintained on -site in
a clearly labeled location, or with the other building maintenance documents and records.
4.0 Health and Safety Considerations
Due to the presence of VOCs in the soil vapor at the Site, the vapors in System piping have the
potential to contain VOC vapors. If the system is functioning properly these compounds are
not likely present at concentrations that pose a risk to the personnel conducting the
inspection, maintenance, and monitoring activities described in this Operation, Maintenance
& Monitoring Manual. Care should be taken to limit exposure to the vapors inside the vent
riser pipe.
5.0 Revision Summary
This OM&M Manual should be reviewed and updated as needed. This section includes a summary of
amendments to this OM&M Plan.

OPERATIONS AND MAINTENANCE FOR VAPOR MITIGATION SYSTEM
1591 Park Road
Chanhassen, MN 55317
There are several components to the existing vapor mitigation system which include the
following:
A Radonaway HS2000 vapor mitigation fan
was installed to induce soil gas
depressurization at the vapor extraction ports to
capture and control the subsurface vapors.
Fan was installed on the exterior of the
building.
Gate valves act like a damper and control the
amount of air flow going through the vertical
risers. The valve is open when pulled out and
closed when pushed all the way in.
On one of the suction point vertical risers is a
U-tube manometer with a colored liquid. It
measures vacuum pressure allowing the
property owner to know at a glance if the vapor
mitigation system is operating or not. Your
original reading will be on the sticker adjacent
to the U-tube as well as the date of install and
fan size.
If the U-tube is at 0 (zero):
A. Verify that the '/4" tube is connected from
the U-tube to the hole in the PVC pipe
B. Verify that the electrical outlet that the fan
is plugged into is working
These components need to be repaired or replaced if noted as being damaged or malfunctioning.
The primary means of determining if the system is operating normally is to observe a normal
operating sound from the fan and that the U-tube manometer is not reading zero.

1.0 SYSTEM DESIGN CONSIDERATIONS
1.1 INTRODUCTION
The HS Series Fan is intended for use by trained, certified/licensed, professional Radon mitigators.
The purpose of this instruction is to provide additional guidance for the most effective use of the HS
Series Fan. This instruction should be considered as a supplement to EPA/Radon Industry standard
practices, state and local building codes and state regulations. In the event of a conflict, those codes,
practices and regulations take precedence over this instruction.
1.2 ENVIRONMENTALS
The HS Series Fan is designed to perform year-round in all but the harshest climates without additional
concern for temperature or weather. For installations in an area of severe cold weather, please contact
RadonAway for assistance. When not in operation, the HS Series Fan should be stored in an area where
the temperature is never less than 32 degrees F. or more than 100 degrees F. The HS Series Fan is
thermally protected such that it will shut off when the internal temperature is above 104 degrees F.
Thus if the HS Series Fan is idle in an area where the ambient temperature exceeds this shut off, it will
not restart until the internal temperature falls below 104 degrees F.
1.3 ACOUSTICS
The HS Series Fan, when installed properly, operates with little or no noticeable noise to the building
occupants. There are, however, some considerations to be taken into account in the system design and
installation. When installing the HS Series Fan above sleeping areas, select a location for mounting
which is as far away as possible from those areas. Avoid mounting near doors, fold -down stairs or other
uninsulated structures which may transmit sound. Insure a solid mounting for the HS Series Fan to
avoid structure -borne vibration or noise.
The velocity of the outgoing air must also be considered in the overall system design. With small
diameter piping, the "rushing" sound of the outlet air can be disturbing. The system design should
incorporate a means to slow and quiet the outlet air. The use of the RadonAway Exhaust Muffler, p/n
24002, is strongly recommended.

1.4 GROUNDWATER
Under no circumstances should water be allowed to be drawn into the inlet of the HS Series Fan as this
may result in damage to the unit. The HS Series Fan should be mounted at least 5 feet above the slab
penetration to minimize the risk of filling the HS Series Fan with water in installations with occasional
high water tables.
In the event that a temporary high water table results in water at or above slab level, water will be
drawn into the riser pipes thus blocking air flow to the HS Series Fan. The lack of cooling air will result
in the HS Series Fan cycling on and off as the internal temperature rises above the thermal cutoff and
falls upon shutoff. Should this condition arise, it is recommended that the HS Series Fan be
disconnected until the water recedes allowing for return to normal operation.
1.5 CONDENSATION & DRAINAGE
(WARNING!: Failure to provide adequate drainage for condensation can result in system failure and
damage the HS Series Fan).
Condensation is formed in the piping of a mitigation system when the air in the piping is chilled below
its dew point. This can occur at points where the system piping goes through unheated space such as an
attic, garage or outside. The system design must provide a means for water to drain back to a slab hole
to remove the condensation.
The use of small diameter piping in a system increases the speed at which the air moves. The speed of
the air can pull water uphill and at sufficient velocity it can actually move water vertically up the side
walls of the pipe. This has the potential of creating a problem in the negative pressure (inlet) side
piping. For HS Series Fan inlet piping, the following table provides the minimum recommended pipe
diameters as well as minimum pitch under several system conditions. Use this chart to size piping for a
system.

1.6 SYSTEM MONITOR AND LABEL
A properly designed system should incorporate a "System On" Indicator for affirmation of system
operation. A Magnehelic pressure gauge is recommended for this purpose. The indicator should be
mounted at least 5 feet above the slab penetration to minimize the risk of filling the gauge with water in
installations with occasional high water tables. A System Label (P/N 15022) with instructions for
contacting the installing contractor for service and also identifying the necessity for regular radon tests
to be conducted by the building occupants, must be conspicuously placed where the occupants
frequent and can see the label.
1.7 SLAB COVERAGE
The HS Series Fan can provide coverage of well over 1000 sq. ft. per slab penetration. This will, of
course, depend on the sub -slab aggregate in any particular installation and the diagnostic results. In
general, sand and gravel are much looser aggregates than dirt and clay. Additional suction points can
be added as required. It is recommended that a small pit (2 to 10 gallons in size) be created below the
slab at each suction hole.
1.8 ELECTRICAL WIRING
The HS Series Fan plugs into a standard 120V outlet. All wiring must be performed in accordance with
the National Fire Protection Associations (NFPA)"National Electrical Code, Standard #70"-current
edition for all commercial and industrial work, and state and local building codes. All wiring must be
performed by a qualified and licensed electrician. Outdoor installations require the use of a U.L. listed
watertight conduit. Ensure that all exterior electrical boxes are outdoor rated and properly caulked to
prevent water penetration into the box. A means, such as a weep hole, is recommended to drain the box.
1.8a ELECTRICAL BOX (optional)
The optional Electrical Box (p/n 20003) provides a weather tight box with switch for outdoor hardwire
connection. All wiring must be performed in accordance with the National Fire Protection Association's
(NFPA)"National Electrical Code, Standard #70 -current edition for all commercial and industrial work,
and state and local building codes. All wiring must be performed by a qualified and licensed electrician.
Outdoor installations require the use of a U.L. listed watertight conduit. Ensure that all exterior electrical
boxes are outdoor rated and properly caulked to prevent water penetration into the box. A means, such
as a weep hole, is recommended to drain the box.
1.9 SPEED CONTROLS
Electronic speed controls can NOT be used on HS Series units.
