Supplemental Environmental Project

� Distressed Property* Inventory

� Phase I ESAs

� Phase II ESAs

� 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

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.

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.

� 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.

� 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.

Inventory Screeningfor Potential Distressed Properties and Rankings

Goodyear Brownfields SEP

� Developed Inventory & Ranking Criteria

� Compiled Inventory of Potential Distressed Properties

� Completed Screening of Potential Distressed Properties

� Ranked Identified Distressed Properties (149 Initially)

� Compiled Final Distressed Properties Inventory (13 Sites)

� Completed Phase I ESAs (11 Sites)

� Former Patterson Property

� Former SAT Site

� City Center Park

� Former Duncan Farms

Property

� Former Silva Property

� Bullard Wash Recreational

Corridor & Linear Park

� 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)

Summary of Recommendations

� 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

� 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

Benefits of Work Performed:

Environmental conditions were favorable for future planning and construction of Goodyear’s proposed City Center

Goodyear Brownfields SEP – Stage 3 Former Public Works Operations Center

■ 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

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

Goodyear Brownfields SEP – Stage 3 Former Duncan Farms

SITE Location

Work Overview: 2011- 2012

Assessed former oil disposal vault

Abandoned two hydraulic lifts

Collected additional samples at

the former tank farm (pesticides)

Conducted geophysical survey to

identify subsurface features

Investigated and removed 18

septic systems and one trash pit

Goodyear Brownfields SEP – Stage 3 Former Duncan Farms – Oil Disposal Vault

Adjacent to Storage Barn and

beneath canopy

Good condition, and did not

appear to have been used for

oil storage or disposal

No contaminants detected

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

No evidence of contamination based on collected soil samples

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

Goodyear Brownfields SEP – Stage 3 Former Duncan Farms – Geophysical Survey

Electromagnetic Survey –

detects metallic or large

subsurface objects (4.7

acres coverage)

Ground Penetrating Radar –

detects contrasts between

different material not limited

to metal (3.4 miles profiled)

Goodyear Brownfields SEP – Stage 3 Former Duncan Farms – Geophysical Survey

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

systems; circa 1940s to 1970s

Systems consisted of a septic tank,

disposal pit, and connecting piping

Systems removed and disposed of

as asbestos material

Debris pit

Septic tank removed in tact Tank showing connecting

pipe penetrations

Separation of clean and native fill

(1,045 tons of clean fill used)

Waste disposal containers

(480 tons of material removed)

Assessed environmental concerns for the west section of the property
