BACKGROUND
The City has been a Rule 19 Party (necessary party) to the North Indian Bend Wash (NIBW) 
Superfund Site since the 1980s. The City's involvement was deemed necessary because 
groundwater contaminated by others with volatile organic compounds (VOCs) is treated and used 
by the City.
During the original Remedial Investigation and Feasibility Study (RI/FS), Area 7 was identified as a 
source area for the contamination. For Area 7, the City was named a Potentially Responsible Party 
(PRP) and became subject to a 1993 Consent Decree related to vadose zone and soil contamination 
due to property ownership and previous graphics operations conducted on a portion of the site. 
Siemens Corporation was also identified as a PRP.
July 2.2026

City Council Report | Administrative Settlement Agreement and Consent Order
The City and Siemens allocated responsibility for Area 7 through the Participation Agreement that 
remains in effect today. Under a separate agreement, Motorola Solutions, Inc. has assumed 
responsibility for fulfilling Siemens' obligations.
In 2017, the EPA identified elevated levels of soil vapor contamination in the surrounding area, 
including apartments located east of the stadium parking lot and Tom Frenkel's event center. 
Remedial measures were subsequently installed at those properties to prevent soil vapors from 
entering the buildings.
In 2023, the EPA issued a demand letter to the City and Siemens requiring a second RI/FS to 
determine the nature and extent of the soil vapor contamination and evaluate whether additional 
remedial actions are necessary.
The EPA requires that the RI/FS be conducted pursuant to an Administrative Settlement Agreement 
and Order on Consent (AOC), executed by the City and Siemens. Motorola will fulfill all of Siemens' 
obligations under the AOC.
ANALYSIS & ASSESSMENT
Overview - Area 7 is located near the intersection of 2nd Street and 75th Street, across from the 
Scottsdale City Court building. The City currently owns approximately one-half of Area 7, which is 
primarily comprised of a City-owned parking lot. The remaining portion of Area 7 is privately owned 
and includes an event center property. Known contamination extends from Area 7 into the parking 
lot immediately south of the site. As part of the RI/FS, additional areas may be investigated, 
including City rights-of-way and adjacent private properties, as necessary to determine the nature 
and extent of the contamination. All investigation findings will be documented in a final RI/FS 
report prepared by Motorola.
Upon Council approval. Motorola anticipates commending the remedial investigation on August 3, 
2026. The investigation is expected to be completed prior to the 2027 Spring Training season. The 
City and Motorola have also negotiated the attached Cooperation and Allocation Agreement, which 
provides for Motorola to perform all obligations required under the AOC. Under the agreement, the 
City is responsible for 20 percent of the costs associated with the RI/FS.
Possible Outcomes - The agreements provide for a comprehensive investigation of remaining soil 
contamination at the site and will allow the EPA to make a final determination regarding any 
additional remedial actions. Upon completion of the remedial investigation, the feasibility study will 
evaluate potential remedies, including no further action, institutional controls, engineering controls, 
and active remediation of the contamination. EPA will evaluate the alternatives and select the 
remedy it determines appropriate under the Comprehensive Environmental Response. 
Compensation, and Liability Act (CERCLA).
Benefits - Completion of the RI/FS is an important step toward resolving outstanding environmental 
issues associated with Area 7. The City has planned improvements to the public parking lot that 
supports Scottsdale Stadium and Spring Training operations. Those improvements have been delayed
Page 2

City Council Report | Administrative Settlement Agreement and Consent Order
pending completion of the environmental review process. Completion of the RI/FS will provide the 
information necessary for the ERA to determine any remaining requirements and may facilitate future 
parking lot improvements.
RESOURCE IMPACTS 
Available funding
Motorola will initially pay all costs associated with the RI/FS. Pursuant to the Cooperation and 
Allocation Agreement, the City will reimburse Motorola for 20 percent of the costs. The City's share 
is estimated to be approximately $360,000. The proposed funding source is water contamination 
settlement funds within the Water Operating Fund, which currently have an available balance of 
approximately $10.3 million.
Future budget implications
Depending on the results of the investigation and subsequent ERA determinations, the City may 
incur additional costs associated with: 1) incorporating engineering controls into the design and 
construction of future parking lot improvements; 2) implementing institutional controls, such as 
deed restrictions on the property; and/or 3) funding a portion of any additional remedial actions 
required by the ERA.
Maintenance Requirements
The City will be responsible for the ongoing operation and maintenance of the parking lot upon 
completion of construction.

IV. EPA’S FINDINGS OF FACT 
EPA makes the following findings of fact:
9. The Indian Bend Wash Superfund Site comprises two separate areas of 
chlorinated solvent groundwater contamination in Scottsdale, Arizona (North Indian Bend Wash, 
“NIBW”) and Tempe, Arizona (South Indian Bend Wash, “SIBW”). Indian Bend Wash was 
added to the National Priorities List (NPL) in 1983 due to the finding of trichloroethylene (TCE) 
and other volatile organic chemicals (VOCs), first in Scottsdale municipal supply wells and 
subsequently in groundwater in Tempe.
TO. The Phase 2 Remedial Investigation and Feasibility Study Report (CH2MHill, 
1991) for NIBW investigated twelve geographic areas, designated as Areas 1 through 12, as well
Page 6 of 30 
City of Scottsdale
Contract No. 2026-124-COS 
19283615

as the City of Scottsdale’s wells and Indian Bend Wash ponds. Area 7 of NIBW is an 
approximately two-acre area on the southeast comer of East Street and North 75*'’ Street in 
Scottsdale, Arizona. The Area 7 Vapor Intrusion Operable Unit is located in NIBW Area 7. Area 
7 includes a City of Scottsdale parking lot, a groundwater treatment system, and the Clayton 
House Event Center (“Event Center”). The area surrounding NIBW Area 7 is mixed use and 
includes City of Scottsdale civic buildings, a public library, a baseball stadium, commercial 
businesses, apartments and single-family homes.
11. 
The Phase 2 Remedial Investigation and Feasibility Study Report (CH2MHill, 
1991) reported evidence of on-site disposal of solvents to the ground at Area 7. Two former Area 
7 businesses were associated with solvent disposal: (1) Dickson Electronics Corporation, a 
Delaware corporation, which operated from 1962-1967, and (2) Rolamech, Inc., an Arizona 
corporation, which operated from 1974-2005.
12. 
Siemens, Motorola, Inc., and GlaxoSmithKline (collectively the “NIBW 
Participating Companies”), along with the Salt River Valley Water Users’ Association, are 
signatories to an Amended Consent Decree entered on June 6, 2003, by the District Court of 
Arizona (“2003 Amended Consent Decree”).
13. 
From 1962 until approximately 1967, Dickson Electronics leased two parcels in 
the northeast corner of Area 7 for the manufacture of electronic components. These parcels now 
constitute the eastern portion of the Event Center and parking area, as depicted generally on the 
maps attached as Appendix C. Dickson Electronics reportedly used trichloroethylene (“TCE”) 
and other solvents on the two parcels.
14. 
In 1997, the City of Scottsdale acquired most of the former Dickson lease parcels 
(then identified as Maricopa County Assessor’s Parcel No. 130-24-005H) under City Council 
Resolution No. 3721, authorizing condemnation for slum clearance and redevelopment under 
Arizona Revised Statutes Title 36. This parcel was reportedly used by the City Parks Department 
for office and storage space. The City sold the former Dickson lease parcels to 7363 LLC, 
predecessor of the current owner, in 2015, retaining rights to reasonable access.
15. 
The northwestern portion of Area 7, currently the western portion of Maricopa 
County Assessor’s Parcel No. 130-24-100 (and formerly referred to as Parcel 130-24-005G) was 
acquired by the City of Scottsdale from Kirsten Brothers Co. in 1972. After the acquisition, the 
City operated a graphics shop and warehouse on this parcel. The City sold this parcel to 7363 
LLC, predecessor of the current owner, in 2015, retaining rights to reasonable access.
16. 
Rolamech owned two parcels of Area 7 from the mid-1970s until 1997 to 
manufacture counter pen holders and operate a machine shop; the westernmost parcel was owned 
by Rolamech from 1974 to 1997 and the easternmost parcel was owned by Rolamech from 1976 
to 1997. These parcels spanned the center of Area 7 from east to west and are now the location of 
a parking lot south of the Event Center, as depicted generally on the maps attached as Appendix 
C. Rolamech reportedly used 1,1,1-trichloroethane and cutting oils on the two parcels.
17. 
In 2005, the City of Scottsdale acquired the Rolamech parcels (then identified as 
Maricopa County Assessor’s Parcel Nos. 130-24-005D and -005J). The City received from EPA
Page 7 of 30
City of Scottsdale 
Contract No. 2026-124-COS 
19283615

a letter dated June 24, 2005 that based on information then available to EPA, identified 
reasonable steps that the City should take to make a Bona Fide Prospective Purchaser claim. In 
connection with the purchase, the City also executed a “Prospective Purchaser Agreement” with 
the State pursuant to Arizona Revised Statutes section 49-285.01 and A.R.S. section 49-292 that 
became effective on June 27, 2006. The City demolished former Rolamech buildings and 
constructed and utilized a parking lot on the former Rolamech lease parcels during its period of 
ownership. The City sold the former Rolamech lease parcels to 7363 LLC, predecessor of the 
current owner, in 2015, retaining rights to reasonable access.
18. 
The current owner of the former Dickson Electronics and Rolamech parcels. Shed 
Scottsdale, LLC, redeveloped the parcels after acquiring them from the City in 2015 and operates 
them as the Event Center, a commercial event space and wedding venue that includes a kitchen, 
two large event rooms, a green room dressing area, three commercial office spaces rented to 
small businesses, and associated parking and landscaped areas.
19. 
The southern portion of Area 7, Maricopa County Assessor’s Parcel No. 130-24- 
004 (“Stadium Parking Lot”) was acquired by the City of Scottsdale in 1986 under City Council 
Resolution No. 2492, authorizing condemnation “to provide additional municipal space to carry 
out the various administrative duties and affairs of the City.” Since its acquisition, the City has 
used the Stadium Parking Lot for parking, storage, city vehicle parking, and as a police impound 
yard. The Area 7 Groundwater Extraction and Treatment System (“GWETS”) is also located on 
this parcel. The Area 7 GWETS was brought on-line in 1999. The GWETS operates to extract, 
contain, and treat contaminated groundwater resulting from past releases of contaminants on the 
property.
20. 
Historically, chlorinated VOCs, including TCE, perchloroethylene, 
dichloroethylene, trichloroethane and chloroform have been detected in certain Area 7 soils 
extending from the vadose zone down to groundwater.
21. 
The primary health risks of TCE include developmental toxicity, reproductive 
toxicity, liver toxicity, kidney toxicity, immunotoxicity, neurotoxicity, and cancer from 
inhalation and dermal exposures.
22. 
The 1991 Vadose Zone and Upper Alluvial Unit (UAU) Groundwater Record of 
Decision for NIBW required Soil Vapor Extraction (SVE) to be implemented at Area 7 to 
address the contaminated soils impacting groundwater. The SVE system operated intermittently 
from 1994 to 2009. Following rebound testing, EPA concurred that the SVE system had met the 
Performance Standards of the Vadose Zone and UAU Groundwater Consent Decree Statement of 
Work. The SVE System was dismantled in 2016. The 2016 Second Five Year Review noted the 
need to re-assess all twelve NIBW former source areas for potential vapor intrusion risk.
23. 
In early 2017, the NIBW Participating Companies in cooperation with EPA 
installed and sampled a number of shallow soil gas sampling points at Area 7 to define the area 
of potential vapor intrusion risk. In April 2017, EPA mobilized the Trace Atmospheric Gas 
Analyzer (TAGA) bus, a mobile laboratory, to NIBW Area 7 after the discovery of 850,000 
pg/m^ TCE in soil gas from one of the sampling points within the City of Scottsdale police 
impound yard on the north side of the Area 7 GWETS, south of the Event Center which was
Page 8 of 30 
City of Scottsdale
Contract No. 2026-124-COS 
19283615

under construction at the time. EPA analyzed soil gas in the adjacent parking lots, as well as 
indoor air within the Event Center and a commercial suite in the location of the forrner Dickson 
Electronics building, as well as an office building directly east of the Event Center and ah 
apartment complex (currently named “The One”) southeast of the Site.
24. 
In 2018, the NIBW Participating Companies installed a sub-slab depressurization 
system in four apartments southeast of Area 7 as a preventative measure against potential vapor 
intrusion from Area 7.
25. 
On July 10,2017, EPA sent a letter to Shed Scottsdale LLC, the owner of the 
former Dickson parcels, recommending that it incorporate a sub-slab vapor mitigation system 
into the design of the new building then under construction oh this property . Shed Scottsdale 
declined to include a mitigation system into the building construction. EPA continued to monitor 
the Event Center after construction was completed, until field activities were terminated in 
March 2020 due to the COVID-19 pandemic. Indoor air sampling resumed in December 2022. 
TCE concentrations measured in Radiello® passive samplers deployed in the building between 
December, 27, 2022, and January 3, 2023, ranged from a minirnum of 2.3 pg/m^ in the northeast 
office suite to a maximum of 21 pg/m^ in the Event Room-East. A siniilar concentration of 20 
pg/m^ was measured in the green room dressing area. A concentration of 7.2 pg/m^ was 
measured in the north central office suite and a maximum of 15 pg/m^ was measured in the 
bathrooms on the east side. EPA found that the 7.2 pg/m^ TCE concentration in the office suites 
exceeded the 7 pg/m^ Commercial/Industrial Accelerated Response Action Level (RAL) for TCE 
established by US EPA Region 9. (EPA, 2014), for a lO-hour workday. The TCE indoor air 
concentrations up to 20 - 21 pg/m^ measured in the green room and Event Room-East also 
approached the 21 pg/m^ Cpmmercial/Ihdustrial Urgent RAL for TCE.
26. 
On February 15, 2023, EPA sent a General Notice Letter to Shed Scottsdale,
LLC, the owner of the Event Center, the City of Scottsdale as the former owner and current 
adjacent property, owner, and Siemens Corporation, as successor to Dickson Electroinics, 
notifying them of these findings and the need to take irnmediate action to reduce indoor air 
concentrations and protect building occupants. In response to the General,Notice Letter, Shed 
Scottsdale installed a sub-slab depressurization system at the Event Center in April 2023. Indoor 
air monitoring performed by EPA’s contractor in May 2023 and January 2024 demonstrated that 
the sub-slab depressurization system is currently effective at mitigating vapor intrusion within 
the Event Center.
27. 
While exposure pathways are currently controlled, remaining contamination in 
soils continues to be a potential source of vapor intrusion fOr current or future buildings at Area 
7.
28. 
Remedial alternatives evaluated in the RI/FS may include institutional or 
engineering controls on properties owned by the Owner Respondent, including the Stadium 
Parking Lot. A Stadium Parking Lot construction project is scheduled to begin in summer 2027, 
and will involve re-pavihg of the area around the GWETS.

Payments by Respondents for Future Response Costs
a. 
Periodic Bills. On a periodic basis, EPA will send Respondents a bill for 
Future Response Costs, including a standard cost surnnaary listing direct costs paid by EPA, its 
contractors, and subcontractors and related indirect costs. Respondents may initiate a dispute 
under Section XIII regarding a Future Response Cost billing, but only if the dispute relates to 
one or more of the following issues: (i) whether EPA has made an arithmetical error; (ii) whether 
EPA has included a cost item that is not within the definition of Future Response Costs; or
(iii) whether EPA has paid excess costs as a direct result of an EPA action that was inconsistent 
with a specific provision or provisions of the NCP. If Respondents submit a Notice of Dispute, 
Respondents shall within the 30-day period, also as a requirement for initiating the dispute, pay 
all uncontested Future Response Costs to EPA in the manner described in ^ 53.b. The dispute 
resolution procedures set forth in this Paragraph in conjunction with the procedures set forth in 
Section XIII shall be the exclusive mechanisms for resolving disputes regarding Respondents’ 
obligation to reimburse EPA for its Future Response Costs. Respondents shall specify in the 
Notice of Dispute the contested costs and the basis for the objection.
b. 
Payment of Bill. Respondents shall pay the bill, or if they initiate dispute 
resolution, the uncontested portion of the bill, if any, within 90 days after receipt of the bill. 
Respondents shall pay the contested portion of the bill determined to be owed, if any, within 30 
days after the determination regarding the dispute. Each payment for: (i) the uncontested bill or 
portion of bill, if late, and; (ii) the contested portion of the bill determined to be owed, if any, 
must include an additional amount for Interest accrued from the date of receipt of the bill through 
the date of payment. Respondents shall make payment at https://wvyw.pav.gov using the “EPA 
Miscellaneous Payments Cincinnati Finance Center” link, and including references to the 
Site/Spill ID number listed in 87 and the purpose of the payment. Respondents shall send 
notice of this payment to EPA.
54. 
Deposit of Payments. EPA may, in its unreviewable discretion, deposit the 
amounts paid under Tf 53 in the Fund, in the Special Account, or both. EPA may, in its 
unreviewable discretion, retain and use any amounts deposited in the Special Account to conduct 
or finance response actions at or in connection with the Site, or transfer those amounts to the 
Fund.
XII. FORCE MAJEURE
55. “Force majeure,” for purposes of this Settlement, means any event arising from 
causes beyond the control of Respondents, of any entity controlled by Respondents, or of
Page 18 of 30 
City of Scottsdale
Contract No. 2026-124-COS 
19283615

Respondents’ contractors that delays or prevents the performance of any obligation under this 
Settlement despite Respondents’ best efforts to fulfill the obligation. Given the need to protect 
public health and welfare and the environment, the requirement that Respondents exercise “best 
efforts to fulfill the obligation” includes using best efforts to anticipate any potential force 
majeure and best efforts to address the effects of any potential force majeure (a) as it is occurring 
and (b) following the potential force majeure such that the delay and any adverse effects of the 
delay are minimized to the greatest extent possible. “Force majeure” does not include financial 
inability to complete the Work or increased cost of performance.
56. 
If any event occurs for which Respondents will or may claim a force majeure, 
Respondents shall notify EPA’s Project Coordinator by email. The deadline for the initial notice 
is 5 days after the date Respondents first knew or should have known that the event would likely 
delay performance. Respondents shall be deemed to know of any circumstance of which any 
contractor of, subcontractor of, or entity controlled by Respondents knew or should have known. 
Within 10 days thereafter. Respondents shall send a further notice to EPA that includes: (i) a 
description of the event and its effect on Respondents’ completion of the requirements of the 
Settlement; (ii) a description of all actions taken or to be taken to prevent or minimize the 
adverse effects or delay; (iii) the proposed extension of time for Respondents to complete the 
requirements of the Settlement; (iv) a statement as to whether, in the opinion of Respondents, 
such event may cause or contribute to an endangerment to public health or welfare or the 
environment; and (v) all available proof supporting their claim of force majeure. Failure to 
comply with the notice requirements herein regarding an event precludes Respondents from 
asserting any claim of force majeure regarding that event, provided, however, that if EPA, 
despite late or incomplete notice, is able to assess to its satisfaction whether the event is a force 
majeure under 55 and whether Respondents have exercised their best efforts under ^ 55, EPA 
may, in its unreviewable discretion, excuse in writing Respondents’ failure to submit timely or 
complete notices under this Paragraph.
57. 
EPA will notify Respondents of its determination whether Respondents are 
entitled to relief under 55, and, if so, the duration of the extension of time for performance of 
the obligations affected by the force majeure. An extension of the time for performance of the 
obligations affected by the force majeure shall not, of itself, extend the time for performance of 
any other obligation. Respondents may initiate dispute resolution under Section XIII regarding 
EPA’s determination within 15 days after receipt of the determination. In any such proceeding. 
Respondents have the burden of proving that they are entitled to relief under ^ 55 and that their 
proposed extension was or will be warranted under the circumstances.
58. 
The failure by EPA to timely complete any activity under the Settlement is not a 
violation of the Settlement, provided, however, that if such failure prevents Respondents from 
timely completing a requirement of the Settlement, Respondents may seek relief under this 
Section.
XIII. DISPUTE RESOLUTION
59. 
Unless otherwise provided in this Settlement, Respondents shall use the dispute 
resolution procedures of this Section to resolve any dispute arising under this Settlement.

INTRODUCTION
Area 7 of the North Indian Bend Wash site is an approximately two-acre area on the southeast comer 
of East 2nd Street and North 75th Street in Scottsdale, Arizona (the Site). A City of Scottsdale parking 
lot and a privately owned event center are located within Area 7. The area surrounding Area 7 is 
mixed use and includes City of Scottsdale civic buildings, a public library, baseball fields and 
associated stadium, commercial businesses, apartments and single-family homes. Area 7 also houses a 
treatment system for remediation of groundwater being conducted pursuant to the Consent Decree II, 
civil action #91-1835 dated April 23, 1992 and the Amended Consent Decree, civil action #91-1835- 
PHX-FJM dated June 6, 2023.
Vadose zone investigations at Area 7 initially commenced in February 1987, with the collection of 
numerous shallow soil gas samples throughout Area 7. Since that time, investigations have been 
conducted in 1988, 1992, 1993, and 1994 which included soil and soil gas sampling. In 1993, a soil 
vapor monitoring and extraction well network was installed and active remediation commenced in 
1994 to address the threat of contaminant migration to groundwater. Approximately 8,000 pounds of 
trichloroethylene (TCE) were extracted from the vadose zone prior to decommissioning the SVE 
system in 2016 with EPA approval.
A comprehensive vapor intrusion and indoor air investigation was prompted in 2016 after TCE 
toxicity values were revised, and the 2016 Five Year Review requested a reassessment of the source 
areas to determine if the existing remedy is protective with respect to vapor intrusion. Subsequent soil 
gas sampling conducted across a broad area within and adjacent to Area 7 demonstrated that 
subsurface vapor concentrations dissipate rapidly away from the source, defining a focus area with 
exceedances of soil gas screening levels used at the NIBW Site during previous vapor intrusion 
investigations. Results from indoor air sampling at Area 7 that followed indicated indoor air 
concentrations exceeded the new long-term TCE regional screening levels in portions of two nearby 
buildings and in one residence located further to the east.
An air filter was deployed by the Participating Companies at the residence to the east, which was 
investigated and deemed to be not directly related to the Area 7 vapor intrusion source. At the 
apartment complex, the Participating Companies installed a sub-slab depressurization system to 
capture and vent TCE to mitigate vapor intrusion in four apartments. Indoor air sampling and 
operations and maintenance events for that system have been conducted annually through 2025 and 
have demonstrated that the system is successfully addressing vapor intrusion at the apartment 
complex. In 2023, EPA requested and oversaw installation of a sub-slab depressurization system in the 
second Area 7 building with indoor air TCE concentration exceedances, an event center. Indoor air 
monitoring performed by EPA’s contractor in May 2023 and January 2024 demonstrated that the sub­
slab depressurization system is effective at mitigating vapor intrusion within the event center.
The 2021 Five Year Review acknowledged protective measures that were already in place (apartment 
complex) or pending at the time (event center) and concluded that for the remedy at the Site to be 
protective in the long term, vapor intrusion concerns in Area 7 need to be addressed. Therefore, EPA 
requested that the Potentially Responsible Parties (PRPs) for the Area 7 vadose zone implement a 
focused Remedial Investigation and Feasibility Study (RI/FS). This Statement of Work (“SOW”) 
reflects a focused effort to supplement historical TCE and other volatile organic compound (VOC) 
data at the Site in order to define the extent of the vapor intrusion source at Area 7 and determine an
Page 3 of 23 
Exhibit B

appropriate permanent remedy.
1.1 
Purpose of the SOW. This SOW sets forth the procedures, requirements, and 
recommendations for implementing the Work to develop and perform the remedial 
investigation (“RI”) and the feasibility study (“FS”) for NIBW Area 7 Vapor Intrusion 
Operable Unit of the Site. This SOW is a part of and incorporated into the 
Administrative Settlement Agreement and Order on Consent, CERCLA Docket No. 
2026-09 (“Settlement”).
1.2 
The terms used in this SOW that are defined in CERCLA, in regulations promulgated 
under CERCLA, or in the Settlement, have the meanings assigned to them in CERCLA, 
in such regulations, or in the Settlement, except that the term “Paragraph” or “Y’ means a 
paragraph of the SOW and that the term “Section” means a section of the SOW, unless 
otherwise stated. If there is a conflict between this SOW and the Settlement, the 
provisions of the Settlement shall govern.
1.3 
At the completion of the RI/FS, EPA will be responsible for identifying a preferred 
remedy, soliciting, and reviewing public comments on the proposed plan, and the 
selection of a site remedy, and will document this selection in a record of decision 
(“ROD”). The remedial action alternative selected by EPA will meet the cleanup 
standards specified in CERCLA § 121. As specified in CERCLA § 104(a)(1), as 
amended, EPA or its representatives will provide oversight of Respondents’ activities 
throughout the RI/FS.
1.4 
Modifications to the SOW will follow procedures described in Sections VII (Performance 
of the Work) and XXI in the Settlement. Respondents shall refer to the Guidance for 
Conducting Remedial Investigations and Feasibility Studies, OSWER 9355.3-01,

REMEDIAL INVESTIGATION
Previous Investigation Summary. The RI/FS Work Plan as described in 14.3 below 
includes a summary of previous investigation results; The sumimary includes available 
data and information relevant for vapor intrusion, including information relating to the 
varieties and quantities of hazardous substances, pollutants, or contaminants at the Site 
and previous remedial actions performed at the Site. Available data includes results from 
previous sampling or other investigations and actions that have been conducted. 
Respondents have referred to Table 2-1 of the Guidance for Conducting Remedial 
Investigations and Feasibility Studies, OSWER 9355.3-01, EPA/540/G-89/004;(Oct. 
1988) for a comprehensive list of data collection information sources. The summary 
describes past reported uses and potential releases of hazardous substances, pollutants or 
contaminants into the environment at the Site to the, extent reliable information is 
available.
Page 6 of 23

4.2
4.3
Conceptual Site Model Development. The Conceptual Site Model (“GSM”) is a 
representation of the Site that summarizes and helps project teams visualize and 
understand available information, and which is updated as additional information 
becomes available. The RI/FS Work Plan as described in 14.3 below includes the Area 7 
Vadose Zone CSM. The CSM is based upon available site-specific information relevant 
to vapor intrusion of VOCs, primarily TCE. References consulted in the development of, 
and the CSM are provided in the RI/pS Work Plan. Respondents shall update the CSM, 
as requested by EPA, to account for information obtained during the W, and summarize 
the updated CSM in the FS Report described in 5.2 below.
Remedial Investigation/Feasibility Study Work Plan (“RI/FS Work Plan”).
Respondents have submitted an RI/FS Work Plan to EPA and ADEQ for review and 
approval consistent with OSWER Directive 9835.1(c). The RI/FS Work Plan includes a 
comprehensive description of the RI Work to be performed, including the scope;, 
methodologies, and schedule for completion. The RI/FS Work Plan describes areas of the 
Site that may pose potential current or future unacceptable risk to public health or welfare 
or the environment due to the release or threat of release of chemicals related to vapor 
intrusion. The RI/FS Work Plan describes the release or threat of release of hazardous 
substances, pollutants or contaminants at or from the Site relevant to vapor intrusion of 
TCE and other pertinent VOCs (collectively referred to in the RI/FS Work Plan as the 
Area 7 Remedial Investigation Vapor Intrusion Constituents of Potential Concern, or RI 
COPCs). Relevant site background information, the CSM for the vadose zone and vapor 
intrusion, and a description of current and anticipated future land use at the Site are 
included in the RI/FS Work Plan.
Respondents have developed a specific project scope based on EPA’s remedial strategy 
for the Site (“Site Strategy”). EPA’s Site Strategy was provided via verbal and email 
communication during a series of meetings and follow-up communications in February 
through May 2024. The RI, as described in the RI/FS Work Plan, consists of collecting 
data to characterize the nature and extent of the RI COPC vapor intrusion source in soil at 
the Site, characterize the magnitude and extent of RI GOPC vapors with the potential to 
result in vapor intrusion into buildings at concentrations above EPA regional screening 
levels (RSLs), and assess risk to human health, including sensitive populations (40 C.F.R. 
§ 300.430(d)(2)(vii)). The FS will evaluate the potential performance and cost of 
treatment technologies to address vapor intrusion at the Site. Although it is not 
anticipated at this time, the RI/FS may include conducting treatability testing as 
necessary to assist in evaluating the potential performance and cost of treatment 
technologies being considered.
Climate-related or environmental hazards (e.g., sea level changes, increased severity of 
wildfire, increased storm intensity, increased flood and/or drought risk, etc.) may affect 
the potential remedies at the Site. To the extent applicable, as part of the FS, Respondents 
shall use forward-looking climate data to evaluate the current and potential chemical 
releases associated with vap|or intrusion of RI COPCs.
A baseline environmental footprint assessment was conducted, as described in the RI/FS 
Work Plan, and presented in the draft Field Sampling Plan submitted to EPA and ADEQ. 
The results of the baseline environmental footprint evaluation were used to identify areas
Page 7 of 23 
Exhibit B

to focus footprint reduction efforts through the application of sustainable Best 
Management Practices (BMPs) during the RI field work. The RI report will include an 
estimate of the reduction in the environmental footprint as a result of the application of 
selected sustainable BMPs. The RI/FS Work Plan is consistent with the Consideration of 
Greener Cleanup Activities in the Superfund Cleanup Process (Aug. 2, 2016). These 
considerations for greener cleanups are not intended to allow cleanups that do not satisfy 
threshold requirements for protectiveness, or do not meet other site-specific cleanup 
objectives. Greener cleanup activities refer to strategies designed to help minimize the 
environmental footprint of cleaning up contaminated sites and ensure a protective remedy 
within the applicable CERGLA statutory and regulatory framework.
4.4 RI/FS Work Plan Deliverables. The Respondents shall submit the following 
deliverables for EPA review and approval unless EPA decides that one or more 
provisions is not necessary . To the extent any of the deliverables below are already in 
place, they need only be supplemented as necessary for this RI/FS;
a) Quality Assurance Project Plan. Respondents shall collect, produce, evaluate, or 
use environmental information under a Quality Assurance Project Plan (“QAPP”) 
reviewed and approved by EPA with ADEQ consultation. No environmental 
information, as defined by AQS/ANSIE-4, will be collected, produced, evaluated, or 
used without an EPA approved QAPP. The QAPP will be consistent with EPA 
Guidance, EPA Quality Assurance Project Plan Standard CIO 2105-S-02.0 (March 7, 
2023), the 2012 Uniform Federal Policy for Quality Assurance Project Plans, 
Optimized UFP-QAPP Worksheets, the most recent version of ASQ/ANSI E-4 
(Quality Management Systems for Environmental Information and Technology 
Programs Requirements with Guidance For Use), and EPA/G-5 (EPA requirements

by EPA. The final QAPP may be combined with the final Field Sampling Plan 
(“FSP”) for submittal to EPA as a single deliverable.
b) Field Sampling Plan. The Field Sampling Plan (“FSP”) shall be written so that 
personnel unfamiliar with the project will be able to gather the samples and field 
information required. The FSP shall be prepared in accordance with RI/FS Guidance. 
A draft FSP has been submitted to EPA and is currently under review by EPA. The 
FSP may be combined with the QAPP for submittal to EPA as a single deliverable.
c) Emergency Response (ER) and Notification Plan. The ER and Notification Plan 
shall describe procedures to be used in the event of an accident or emergency at the 
Site (e.g., power outages, water impoundment failure, treatment plant failure, slope 
failure, etc.). The ER and Notification Plan will be incorporated into the Health 
and Safety Plan (“HASP”) addendum described below and shall include:
(1) 
Name of the person or entity responsible for responding in the event of an 
emergency incident;
(2)

measures to prevent, and contingency plans for spills and discharges);
(4) 
Notification activities in accordance with 16.6(B) (Release Reporting) in 
the event of a release of hazardous substances requiring: reporting under 
sections 103 or 111(g) of CERCLA, or section 304 of the Emergency 
Planning and Community Right-to-know Act (“EPCRA”), 42 U.S.C.
§ 11004;and
(5) 
A description of all necessary actions to ensure compliance with Section 
6.6 (Emergency Response and Reporting) in the event of an occurrence 
during the performance of the Work that causes or threatens a release of a 
hazardous substance, pollutant or contaminant at or from the Site that 
constitutes an emergency or may present an immediate threat to human 
health or welfare or the envirorunent.
d) Health and Safety Plan. A Health and Safety Plan (“HASP”) for use during the Rl 
field investigation will be prepared prior to implementation of the RI field program. 
The HASP will include the ER and Notification Plan described in 4.4(c) above. The 
HASP shall describe all activities to be performed to protect on-site personnel from 
physical, chemical, and all other hazards posed by the field sampling. The HASP 
shall: (1) be prepared in accordance with EPA’s Emergency Responder Health and 
Safety Manual and Occupational Safety and Health Administration (“OSHA”) 
requirements under 29 C.F.R. §§1910 and 1926; and (2) shall address RI Work and 
include contingency planning. A draft HASP has been submitted to EPA and is 
currently under review by EPA. EPA does not approve the HASP but will review it 
to ensure that all necessary elements are included and that the plan provides for the 
protection of human health and the environment.
e) Identification of Preliminary RAOs, PRGs and ARARs. In the RI/FS Work 
Plan, Respondents have developed preliminary remedial action objects (“RAOs”), 
which are medium-specific goals for protecting human health or the environment 
that specify the chemicals of concern, exposure route(s) and receptor(s), and 
preliminary remediation goals (“PRGs”). Respondents have also identified potential 
state and federal chemical-specific and location-specific applicable or relevant and 
appropriate requirements (“ARARs”). ARAR identification will continue as site 
conditions, contamination, and remedial action alternatives are refined. RAOs, 
ARARs, and PRGs will be refined if necessary and provided in the FS report as 
described in T| 5.2(A).
4.5 Field Summary Report. Respondents shall prepare a report after the field activity
demobilization and receipt and validation of field and laboratory data that summarizes 
the sampling results, describing the collection, processing, management, distribution, and 
archival of data and information. This report will be reviewed and approved by EPA with 
ADEQ consultation.
Page 9 of 23 
Exhibit B

4.6 
Baseline HHRA. Respondents shall perform the Baseline Human Health Risk 
Assessment (“Baseline HHRA”) in accordance with this SOW and the NCP (National 
Contingency Plan), including the 40 C.F.R. § 300.430(d)(2)(vii) provision on sensitive 
populations, RI/FS Work Plan, and applicable EPA guidance. The purpose of the 
Baseline HHRA is to provide an understanding of the potential risks to human health 
associated with current and anticipated future land use to support risk management 
strategies and to inform the public regarding possible risks. The Baseline HHRA shall 
evaluate human health risk associated with potential exposure to RI COPCs as if no 
interim mitigation measures have been taken, as well as under current conditions where 
mitigation measures have been implemented. Respondents shall ensure that the Baseline 
HHRA incorporates site-specific exposure assumptions, to the extent possible. Site- and 
use-specific exposure assumptions shall be developed and applied in the risk assessment. 
The risk assessment will be reviewed and approved by EPA with ADEQ consultation. 
Respondents shall identify and document all sources of information reviewed to assess 
human health risks.
4.7 
Draft RI Report. Respondents shall submit to EPA for review and approval pursuant to 
^ 7.5 (Approval of Deliverables), a draft RI report consistent with the SOW, RI/FS Work 
Plan, and with EPA guidance and regulations. This report shall summarize results of field 
activities to characterize the Site, including the sources, nature and extent, and fate and 
transport of contaminants relevant to vapor intrusion of RI COPCs at the Site.
Respondent will refer to the RI/FS Guidance for an outline of the report format and 
contents. Following receipt of comments by EPA and ADEQ, Respondents will prepare a 
final RI report which satisfactorily addresses these comments.
5.
FEASIBILITY STUDY
5.1 Feasibility Study. Consistent with relevant RI/FS Guidance and results of the Baseline 
HHRA, the FS shall identify and evaluate remedial alternatives to prevent, mitigate, or 
otherwise respond to or remediate the release or threatened release of hazardous 
substances, pollutants or contaminants relevant to vapor intrusion of RI COPCs at or 
from the Site. If there is potential commingling of hazardous substances with pollutants 
or contaminants at the Site, then the evaluation of the potential performance and cost of 
the treatment technologies should also take into account the ability of those treatment 
technologies to address the commingled contamination (e.g., hazardous substances 
comingled with pollutants or contaminants) and any adverse impacts the comingled 
contamination may have on the ability and cost of the treatment technologies to address 
the release or threatened release at the Site. The remedial alternatives evaluated shall 
include, but shall not be limited to, the range of alternatives described in the NCP, 40 
C.F.R. § 300.430(e), and shall include remedial actions that utilize permanent solutions 
and alternative treatment technologies or resource recovery technologies to the extent 
practicable. Pursuant to NCP 40 C.F.R. § 300.430(e), a preliminary screening step will be 
implemented to eliminate from consideration alternatives that are technically or 
administratively infeasible. Respondents shall also evaluate potential impacts that 
treatment technologies have on other hazardous substances, pollutants or contaminants at 
or from the site. In evaluating the alternatives. Respondents shall address the factors 
required by section 121 of CERCLA, and 40 C.F.R. § 300.430(e).
Page 10 of 23 
Exhibit B

5.2 FS Deliverables. The Respondents shall prepare a draft and final FS report for EPA 
review and approval that includes the following components, unless EPA decides that 
one or more provisions is not necessary:
(A) 
Refine RAOs, PRGs and ARARs. Respondents shall revise the RAOs, PRGs, 
and ARARs to include potential ARARs specific to actions and locations 
described in f 4.4(e) based on the findings of the Baseline HHRA and RI Report. 
Respondents will review and, if necessary, modify the site-specific RAOs, 
specifically the PRGs, that were established in the RI/FS Work Plan, and 
considering comments made by EPA. The revised RAOs and PRGs will be 
documented in the FS Report that will be reviewed and approved by EPA. These 
modified PRGs will specify the contaminant(s) and media of interest, exposure 
pathways and receptors, and an acceptable contaminant level or range of levels (at 
locations for each exposure route), basis for the value, and the associated residual 
risk. This analysis will include the consideration of sensitive subgroups in 
determining the acceptable exposure levels for sites with systemic toxicants, in 
accordance with 40 G.F.R. § 300.430(e)(2)(i)(A)(l). In addition, the analysis will 
include, if relevant, whether the ARARs may not be sufficiently protective given 
the presence of multiple contaminants at the site or multiple pathways of 
exposure for sites with known or suspected carcinogens, in accordance with 40 
C.F.R. § 300.430(e)(2)(i)(A)(2).
(B) 
Identify and Evaluate Remedial Technologies and Assemble Alternatives.
Concurrent with^ 5.2(A), Respondents shall assemble combinations of 
technologies, and the media to which they would be applied, into remedial 
alternatives that address contamination for the Area 7 Vapor Intrusion Operable 
Unit. This analysis will be included in the FS Report and reviewed and approved 
by EPA with ADEQ consultation. Respondents shall: (i) develop general response 
actions to address RI COPG vapor intrusion impacts at the Site that may be taken 
to satisfy the RAOs for the Site; (ii) identify volumes or areas of media to which 
general response actions might be applied, taking into account the requirements 
for protectiveness as identified in the RAOs and the cheniical and physical 
characterization of the Site; and (iii) identify and screen the technologies 
applicable to each general response action to eliminate those that cannot be 
implemented technically at the Site. The general response actions shall be further 
refined to specify remedial technology types, as appropriate (e.g., the general 
response action of treatment can be further defined to include chemical or 
biological technology types). Respondents shall assemble the selected 
representative technologies into alternatives representing a range of treatment and 
containment combinations, as appropriate.
(G) Comparative Analysis of Alternatives. After completion of T| 5.2(A) and (B),
Respondents shall conduct a comparative analysis of the remaining alternatives to 
evaluate the relative performance of each alternative in relation to the nine 
evaluation criteria identified below in this paragraph and include a summary of 
this analysis in the FS Report. This range of alternatives shall include, as
Page 11 of 23 
ExhibitB

appropriate, options in which treatment is used to reduce the toxicity, mobility, or 
volume of wastes, but varying in the types of treatment, the amount treated, and 
how long-term residuals or untreated wastes are managed. The analysis will 
include options involving treatment and/or containment and a no-aetion 
alternative. The evaluation criteria are: (1) overall protection of human health and 
the environment; (2) compliance with ARARs; (3) long-term effectiveness arid 
permanence; (4) reduction of toxicity, mobility, or volume through treatment; (5) 
short-term effectiveness; (6) implementability; (7) cost; (8) state (or support 
agency) acceptance; and (9) community acceptance. Criteria (1) and (2) are 
Threshold Criteria, statutory requirements that must be satisfied by any alternative for 
it to be eligible as a selected alternative. Criteria (3) through (7) are Primary Balancing 
Criteria, used to identify major tradeoffs between remedial alternatives which are 
balanced to identify the preferred alternative and to select the final remedy. Criteria (8) 
arid (9) are Modifying Criteria, fully considered after any public comment period on 
EPA’s Proposed Plan for the Site. The analysis shall (consisterit with 40 G.F.R.
§ 300.430(e)(9)(iii)(C) and Consideration of Climate Resilience in the Superfund 
Cleanup Process for Non-Federal National Priorities List Sites OLEM 9355.1- 
120, June 30, 2021) include an assessment of the vulnerability of the 
protectiveness of each alternative to the impacts of climate change and, for each 
alternative where appropriate, an evaluation of the possible addition of further 
measures to ensure the resilience of a particular alternative’s protectiveness to the 
impaets of climate change. In addition, where appropriate for particular evaluation 
criteria. Respondents shall also evaluate, to the extent practicable, opportunities to 
reduee the environmental footprint of each alternative. Such evaluation shall 
include the consideration of green remediation best management practiees and/or 
application of the ASTM Standard for Greener Cleanups, consistent with 
Consideration of Greener Activities in the Superfund Cleanup Process (Aug. 6, 
2016). These considerations for greener cleanups are not intended to allow 
cleanups that do not satisfy threshold requirements for protectiveness, or do not 
meet other site-specific cleanup objectives.
For each alternative. Respondents shall provide: (1) a description of the 
alternative that outlines the waste management strategy involved and identifies 
the key ARARs associated with each alternative, and (2) a discussion of the 
individual criterion assessment. If the Respondents do not have direct input on 
criteria (8), state (or support agency) acceptance, and criteria (9), community 
acceptance, these will be addressed by EPA. Criteria (8) and (9) are not generally 
addressed until after the Proposed Plan.
(D) IC Evaluation. Concurrent with f 5.2(A), Respondents shall conduct an
institutional control (IC) evaluation as appropriate based on the findings of the 
Baseline HHRA and RI Report. ICs need to be enforceable under CERCLA, 
rather than relying on local controls, such as zoning. The IC evaluation will 
describe potential land and/or resource use restrictions and their relationship to 
the RAOs. The IC evaluation will also identify potential IC instruments, 
including those persons potentially responsible for implementing, maintaining, 
and enforcing the ICs. The IC evaluation will include an estimate for how long IC
Page 12 of 23 
Exhibit B

(E)
instruments shall remain in place. The IC evaluation shall also identify how the 
IG components may be utilized in conjunction with each remedial alternative 
evaluated per the NCP (40 C.F.R. § 300.430(e)(9)(iii)) such as: compliance with 
ARARs; long-term effectiveness and permanence; short-term effectiveness; 
implementability; cost; state acceptance; and community acceptance. The IC 
analysis shall be included in the FS Report submitted for review arid approval by 
EPA.
Draft FS Report. Following Tn|5 .2(A) through (D), Respondents shall submit to 
EPA a draft FS report for review and approval pursuant to ^ 7.5 (Approval of 
Deliverables). Respondents shall refer to Table 6-5 of the RI/FS Guidance for 
report content and format. The FS report and the administrative record shall 
provide sufficient information to support the remedial alternatives analysis and 
remedy selection under sections 113(k) and 117(a) of CERCLA. Respondents will 
prepare a final FS report which satisfactorily addresses EPA and ADEQ 
comments.
6.
MEETINGS, PERMITS, and REPORTS
6.1 
Kickoff Meeting. Within 14 days of the Effective Date of the Settlement, if deemed 
necessary, Respondents shall schedule a kickoff meeting with technical staff,,EPA, and other 
stakeholders to discuss this SOW and the RI/FS Work Plan. EPA and the Respondents will 
discuss the site-specific objectives of the RI. The meeting will also be used to outline project- 
specific requirements including: field prpgram objectives, data gaps, potential sampling and 
analysis methods, and performance goals. The deliverable after the kickoff meeting will be an 
updated project schedule if changes to the schedule previously presented in the RI/FS Work 
Plan are necessary. The kickoff meeting and progress reports delivered during monthly 
Technical Committee meetings referenced in f 6.2 will be documented in the QAPP.
6.2 
Progress Report Meetings. The Respondents, EPA, ADEQ, and other Technical 
Committee parties hold meetings for the NIBW site on a consistent and typically 
monthly basis. Progress reports for the RI/FS Work will be given by the Respondents 
to the Technical Committee, including EPA, during these project Technical Committee 
meetings through completion of the RI/FS Work. The progress reports will be 
documented in meeting minutes prepared and distributed by the Participating 
Companies following each meeting, and will generally cover the following, as 
appropriate:
(A) 
Actions that have been taken under this SOW;
(B) 
Results of sampling and tests and other data received and passed 
through the initial QA process by Respondents;
(C)

(“IDW”) from the Site to an off-site facility only if they comply with section 121(d)(3) of 
CERCLA, section 300.440 (“Off-Site Rule”) of the NGP, EPA’s Guide to Management 
of Investigation Derived Waste, OSWER 9345.3-03FS (Jan. 1992). Wastes shipped off­
site to a laboratory for characterization, and RGRA hazardous wastes that meet the 
requirements for an exemption from RGRA under 40 G.F.R. § 261.4(e) shipped off-site 
for treatability studies, are not subject to section 300.440 of the NGP.
6.5 
Permits
(A) 
As provided in GERGLA § 121(e), and siection 300.46o(e) of the NGP, no permit 
is required for any portion of the Work conducted entirely on-site (i.e., within the 
areal extent of contamination or in very close proximity to the contamination and 
necessary for implementation of the Work). Where any portion of the Work that 
is not on-site requires a federal or state permit or approval. Respondents shall 
submit timely and complete applications and take all other actions necessary to 
obtain all such permits or approvals.
(B) 
Respondents may seek relief under the provisions of Section XII (Force Majeure) 
of the Settlement for any delay in the performance of the Work resulting from a 
failure to obtain, or a delay in obtaining, any permit or approval referenced in
^ 6.5(A) and required for the Work, provided that they have submitted timely and 
complete applications and taken all other actions necessary to obtain all such 
permits or approvals.

Cooperation and Allocation Agreement
This Agreement, effective____________ , 2026, is entered into by the City of Scottsdale (City),
and Motorola Solutions, Inc. (Motorola) as indemnitor of Siemens Corporation (Siemens). City 
and Motorola are jointly referred to here as the "Parties."
The premises for this Agreement are as follows:
A. The Environmental Protection Agency (EPA) has requested that the City and Siemens 
enter into an Administrative Settlement Agreement and Order on Consent (AOC) to 
conduct a Remedial Investigation and Feasibility Study (RI/FS) at Area 7 Vapor Intrusion 
Operable Unit of the North Indian Bend Wash (NIBW) Superfund Site (Site) in connection 
with potential vapor intrusion resulting from volatilization of volatile organic compounds 
in the subsurface.
B. The request is being made under EPA's authority granted by the Comprehensive 
Environmental Response, Compensation and Liability Act (CERCLA).
C. Area 7 includes property owned and operated by the City, property formerly owned and 
operated by the City, and facilities formerly operated by Dickson Electronics Corp, a 
predecessor to Siemens.
D. CERCLA imposes strict liability on certain current or former owners or operators of 
property and EPA has alleged that the City and Siemens are potentially responsible 
parties under CERCLA's liability provisions. The City and Siemens deny the allegation.
E. Motorola is an indemnitor of Siemens with respect to certain claims made against 
Siemens in connection with the NIBW Site.
F. Motorola has conducted work at Area 7 required of the City and Siemens under a 
consent decree entered by them in 1992 in United States of America v. Motorola. Inc. et 
ai.. Civil Action No. 91-1835-PHX (Consent Decree II). Specifically, Motorola has 
conducted "Vadose Zone Work" as defined in Consent Decree II for Area 7 and as 
identified in a September 12,1991, Record of Decision. Motorola has incurred at least 
$245,000 in conducting this work and has not to date sought reimbursement from the 
City for these costs.
G. In response to EPA's 2"'* Five-Year Review for the NIBW Site in 2016, the potential for 
vapor intrusion at Area 7 was noted as an issue preventing EPA from concluding that the 
remedy at the NIBW Site is protective of human health for the long term. As a result. 
Motorola has been conducting work at historical source areas In NIBW to investigate 
potential vapor intrusion. Most of this work conducted to date has been at Area 7, the 
only historical source area deemed to have concerns for vapor intrusion. Motorola has 
incurred at least $470,000 in response costs in conducting this work at Area 7 through 
March 2023. Motorola has not to date sought reimbursement from the City for these 
costs.
H. In response to EPA's request to the City and Siemens in early April 2023 to begin 
negotiation of an AOC to conduct an RI/FS for Vapor Intrusion at Area 7, Motorola has 
conducted work pertaining to EPA's request, including evaluation of the requirements of 
EPA's AOC and associated Statement of Work (SOW); technical analyses pertaining to the
AREA 7 VI RI/FS

potential for vapor intrusion at Area 7; preparation of multiple drafts of an Area 7 RI/FS 
Work Plan; preparation for and participation in numerous technical meetings with EPA 
regarding the scope of the RI/FS; review of and addressing EPA comments on the draft 
work plan; preparation of associated RI/FS documents including the Field Sampling Plan 
(FSP), Quality Assurance Project Plan (QAPP), Emergency Response and Notification Plan 
(ERNP), and Health and Safety Plan (HASP); and negotiations with the City and EPA 
pertaining to the AOC and SOW. Motorola has incurred at least $870,000 in response 
costs in conducting this work at Area 7 since April 2023. Motorola has not to date sought 
reimbursement from the City for these costs.
I. 
The City is planning improvements to a parking facility within Area 7 to satisfy 
contractual obligations it has to the San Francisco Giants, a baseball team that conducts 
spring training at a stadium adjacent to the parking facility. Construction of these 
improvements is scheduled to begin in 2026.
J. 
The City and Motorola have a mutual interest in integrating field work for the RI/FS so 
that it complements and does not interfere with the City's planned improvements.
K. The City and Motorola also have a mutual interest in (a) completing the RI/FS and 
conducting remedial action in a cost-effective, efficient manner; and (b) allocating the 
costs of the RI/FS and the future remedy as required in an equitable manner.
L. A CERCLA-quality Human Health Risk Assessment established that there is no significant 
human health risk posed by the conditions in Area 7 under reasonable exposure 
scenarios. Vapor mitigation systems are in place in buildings or apartments where 
warranted by historic vapor sampling to mitigate potential exposure to persons visiting 
or living in such structures. The City and Motorola are willing to undertake the RI/FS to 
avoid the costs of dispute resolution with EPA and to advocate for mitigation, 
monitoring, and institutional/engineering controls as the most appropriate remedy 
under CERCLA for Area 7.
Therefore, in consideration of the mutual promises contained in this Agreement, the City and 
Motorola agree to the following.
1. Cooperation. The Parties will cooperate with each other to achieve the complefon of 
the Area 7 Vapor Intrusion Operable Unit RI/FS, any other future response actions at 
Area 7, and ongoing operation and maintenance of the current and any future Area 7 
remedial action in a cost-effective, efficient manner.
2. RI/FS Work Plan. Motorola submitted a work plan for the RI/FS, which the City has 
approved, to EPA in December 2024. EPA provided comments on the work plan in April 
2024 and Motorola submitted a revised work plan, which the City has approved, to EPA 
in October 2025. Motorola initially submitted the QAPP and FSP to EPA in September 
2025. A revised FSP was submitted to EPA in December 2025 and a revised FSP was 
submitted to EPA in February 2026. The HASP for the project which includes the ERNP 
was submitted to EPA in October 2025. The Parties will cooperate in advocating to EPA 
the adoption of the work plan by EPA.
3. Contractor. After the AOC is executed. Motorola will implement the work plan for the 
RI/FS using Montgomery & Associates (Montgomery) as its primary contractor.

4. AOC Insurance Requirement. Motorola will ensure that Montgomery carry insurance 
that satisfies the insurance requirements of the AOC, or otherwise will be responsible for 
satisfying the insurance requirements of Section X of the AOC.
5. Completion of the RI/FS. Motorola will proceed in as expeditious a manner as is 
reasonably practicable to complete the RI/FS. The City will use its best efforts to facilitate 
the expeditious completion of the RI/FS. The City acknowledges that Motorola is not 
accountable for delays due to EPA's review and approval of deliverables, or other 
demands or requirements of EPA.
6. Coordination of Work. To the extent reasonably practicable, the Parties will coordinate 
field work for the Rl and any future remedial action at Area 7 with the City's contractor 
for the City's planned improvements at the parking facility at Area 7.

contractors will be approved by Motorola and provided to the City for review. The 
Parties shall endeavor to reach a consensus on the content of each submittal. If they are 
unable to reach a consensus, Motorola shall have the final say on the content of each 
submittal.
8. Financial Assurance and Stipulated Penalties under the AOC. Motorola shall be solely 
responsible for satisfying the financial assurance requirements of the AOC. Should 
stipulated penalties be imposed by EPA against the Respondents (Siemens and the City 
other than with respect to the City's obligations as an Owner Respondent) under Section 
XIV of the AOC, Motorola will be solely responsible for satisfying the stipulated 
penalties. The City will be solely responsible for stipulated penalties imposed on the City 
with respect to the City's obligations as an Owner Respondent.
9. Conferences with EPA In-Person or Remotely. The City and Motorola will participate 
together in conferences with EPA and, when requested by either Party, will engage in a 
planning call or conference to outline talking points for the conference with EPA. The 
Parties will not engage in independent discussions or sharing of information with EPA 
concerning the RI/FS or associated remedial actions.
10. Allocation of Response Costs. The City and Motorola will share all costs of the RI/FS, 
including but not limited to EPA and Arizona Department of Environmental Quality 
(ADEQ) oversight and response costs, as follows:

purposes to support a liability claim, (2) made the part of any oral or written liability 
argument to a trier of fact, or (3) used in any press release with respect to CERCLA 
liability claims or arguments. Forthe avoidance of doubt, the parties' mutual goal is to 
maintain a level playing field that, if the need arises, allows Area 7 liability arguments to
