� Remedial Actions
* Any real property, the expansion, redevelopment, or reuse of
which may be complicated by the presence or potential presence of a hazardous substance, pollutant or contaminant.
Goodyear Brownfields SEPProject Overview
Goodyear Brownfields Supplemental Environmental Project
Overview ofGoodyear SEP Stages
� Stage One:
– Conduct inventory of Distressed Properties* located within the boundaries of the City of Goodyear.
– Complete up to 25 Phase I Environmental Site Assessments (ESAs) for identified Distressed Properties.
* - Any real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or
potential presence of a hazardous substance, pollutant or contaminant.
� Stage Two:
– Narrow down Distressed Properties identified within Stage One
to at least 4 candidate properties for further investigation and/or
redevelopment.
– Complete up to four Phase II ESAs for identified Distressed
Properties.

Overview of Goodyear SEP Stages
� Stage Three:
– Narrow down Distressed Properties identified within Stage Two
to at least three candidate properties for remedial actions.
– Conduct remedial action activities for at least three Distressed
Properties.
Goodyear Brownfields Supplemental Environmental Project
Stage One: Inventory
� Location Criteria:
– Located, in whole or in part, with the City of Goodyear.
– Distressed Properties within historic district or El Rio
Watercourse Master Plan will be given preference.
– Not within boundaries of the PGA Superfund site (North or
South).
– Located close enough to existing infrastructure to make
redevelopment economically feasible or must have other
desirable characteristics.
Goodyear Brownfields Supplemental Environmental Project
Stage One: Inventory
� Benefits to Community:
– Redevelopment of Distressed Property would provide a
direct or indirect benefit to the citizens of the City of
Goodyear.
– At least one Distressed Property should be large enough
(greater than one acre) on its own or in conjunction with
adjacent parcels to accommodate multiple building sites,
that may be used for a public or private educational
institution.
Goodyear Brownfields Supplemental Environmental Project
Stage One: Inventory
� Excluded Properties:
– Currently subject to a federal or state environmental permit, administrative order or consent decree.
– Subject to a current or formerly implemented federal or state environmental corrective action or closure plan.
– Owned by the United States, in fee title, or owned by Crane Co. or one of its subsidiaries or affiliates.

� Public Works Operations – Abandon monitor wells
and remediation wells. Flush, cap and leave horizontal
piping in place.
� Patterson
� Secure/lock and/or abandon domestic and irrigation wells
� Additional sampling near the concrete pad (arsenic)
� Former SAT – Toxaphene concentrations in soil samples
may be an issue if developing the site as a school or day
care facility (10-6 risk factor)
Goodyear Brownfields SEP
Summary of Recommendations
Goodyear Brownfields Supplemental Environmental Project
� City Center Park - Toxaphene concentrations in soil
samples may be an issue if developing the site as a
school or day care facility (10-6 risk factor)
� Duncan Farms
� Properly close cesspools and septic system that are no
longer in use (excavate and collect samples)
� Remove hydraulic lifts and collect soil samples
� Additional sampling near former tank farm (dieldrin)
� Remove oil disposal pit (and arsenic-contaminated soils)
and collect soil samples

Summary of Recommendations
Goodyear Brownfields Supplemental Environmental Project
� Former Silva Property – No further actions
recommended at this time
� Bullard Wash Recreational Corridor – No further
actions recommended at this time

Goodyear Brownfields SEP – Stage 3Former SAT and City Center Park Sites
Work Overview
� Defined extent of
toxaphene
contamination
� Determined if levels of
toxaphene were a
human health risk
� Determined if further
characterization or
action was required
Sampling Activities - 2011:
■ Drilled 48 direct-push soil borings to 5 feet below ground surface
■ Collected soil samples at depths of 1, 3, and 5 feet
■ Analyzed samples for toxaphene
Goodyear Brownfields SEP – Stage 3 Former SAT and City Center Park Sites
Summary of Findings:
Vertical extent of toxaphene is < 3 feet in depth
Horizontal extent of toxaphene is limited to small areas surrounding individual sample locations
Based on results of a Human Health Risk Assessment, toxaphene does not present a human health risk

■ Abandonment of wells associated with a former LUST remediation system
■ Abandonments were conducted per ADWR protocol
Goodyear Brownfields SEP – Stage 3 Former Public Works Operations Center
Benefits of Work Performed:
Assessed environmental concerns for the property
Removed potential physical and environmental hazards associated with former remediation wells located on the property
Permitted and completed well abandonments for the City under SEP funding
Work was performed without disruption to City operations

above regulatory levels.
Goodyear Brownfields SEP – Stage 3 Former Duncan Farms – Hydraulic Lifts
Hydraulic Lift #1 Hydraulic Lift #2 Decanting oil
No evidence of leaks or damage

Goodyear Brownfields SEP – Stage 3 Former Duncan Farms – Former Tank Farm
Installed 4 soil borings near former tank farm where dieldrin was previously detected
Samples collected at three depth intervals
Dieldrin detected in 5 of 12 samples (<0.0050 to 0.21 mg/kg)
Samples were below regulatory limits; however, the maximum concentration was detected in the deepest sample

subsurface objects (4.7
acres coverage)
Ground Penetrating Radar –
detects contrasts between
different material not limited
to metal (3.4 miles profiled)

4 Areas of Interest (possible septic systems)
Utilities confirmed No fuel USTs
Goodyear Brownfields SEP – Stage 3 Former Duncan Farms – Subsurface Feature Investigation
Located and removed 23 septic
