Site History – Starkey Junk Yard
!
Over sixty years as an
auto salvage yard.
!
Mixed industrial and
residential use.
!
Numerous potential
releases
!
Currently a blight and a
hazard to the residents
of Uhrichsville.
Starkey Junk Yard - Adjacent Property
Starkey Junk Yard - Adjacent Property
Site Background
Auto salvage yard on the Property since
before 1938.
! All potential sources and source areas
associated with on-Property activities.
! Potential releases:
!
"
"
"
Salvage operations including automotive fluids,
used batteries, scrap metals and burned tires.
Scrap tire fire in 1985.
Open dumping complaint in 2002 – industrial
waste, metal, oil, welding materials and slag.
Identified Area Summary
!
!
Identified Area #1:
Junk Shop Area
(Existing building and
concrete pads from
former buildings).
Potential sources
include automotive
fluids and batteries.
COCs include VOCs,
SVOCs, TPH and
Metals.

Identified Area #2:
Compactor Area
(Concrete pad in
southwest portion of scrap
yard where hydraulic
pumps were used to
operate a compactor).
Potential sources include
automotive fluids,
hydraulic oils (possibly
containing PCBs), metals
and batteries. COCs
include VOCs, SVOCs, TPH,
PCBs and Metals.

Identified Area #3:
Scrap Yard Area
(The remainder of the
Property).
Potential sources
include automotive
fluids, metals and
batteries. COCs
include VOCs, SVOCs,
TPH and Metals.
Proposed Reuse
!
!
!
The Village of Uhrichsville
wishes to reuse the
property as a park and
baseball diamond.
The village sought a
grant-funded targeted
brownfield assessment
(TBA) from Ohio EPA to
provide support for a VAP
Phase II investigation.
The results will be used as
part of an application for
Clean Ohio Fund cleanup
money.
Requesting a TBA
!
Submit a TBA application form and formal
request letter.
!
Receive request for additional information,
explanation of deficiencies, or invitation to
a kickoff meeting from Ohio EPA.
!
Attend kickoff meeting to discuss scope of
project.
!
Work with district or SIFU to develop work
plan and data quality objectives (DQO).
TBA Process
!
!
Ohio EPA staff visited
the site and learned
the community’s
assessment needs.
A DQO scoping
meeting was held
between Ohio EPA
staff, the community
and their CP prior to
developing a work
plan.
TBA Process
!
DQO scoping meeting
"
!
Benefits of coordination between CP,
community and agency
Staff, personnel, field work, etc.
A meeting of
public and private
interests.
CP’s Goals for DQO Meeting
!
!
!
Discuss proposed
ecological studies by
SIFU to characterize
sensitive ecological
receptors.
Identify geologic and
hydrogeologic conditions
below the Property.
Collect both POC and
subsurface soil samples
in Identified Areas.
!
!
!
!
Collect screening data to
characterize ground
water across the
Property.
If possible, use a VAP
Certified Laboratory to
perform analysis.
Assure that laboratory
MDL’s comply with VAP
generic standards.
Request the CL provide
a VAP Affidavit along
with their reports.
DQO Scoping Meeting
Discussion Agenda Outline
I. Introductions
II. State/Define the
Problem (describe the
data-gathering activities)
▪ i.e. - Adequately assess the
contamination problem(s)
that might exist at the site.
III.Identify the Decision
▪ i.e. - Collect data of
sufficient quality and
quantity in order to provide
the basis for the identified
further action(s) at the site.
IV. Identify Inputs to the
Decision
▪ C-O-C’s?
▪ VAP considerations?
▪ Enforcement Issues?
▪ Other potential technical
issues?
V. Define the Study
Boundaries
▪ Physical characteristics of
the site/property
▪ Eco Assessment
▪ Groundwater issues?
▪ Additional areas to
investigate (waste piles,
storage tank area, etc.)?
DQO Scoping Meeting
Discussion Agenda Outline
VI. Develop a Decision
Rule
“If the concentration of
contaminants at
_________________
exceed _____________
then the site shall
be__________,.....”
VII. Specify Limits on
Decision Errors
▪ Soil Borings (method/
location/number/depth)
▪ Piezometers
(method/location/
number/depth)
▪ Groundwater Samples
(method/location/number/
depth)
▪ Soil Sampling (Procedures/
analytes/methods)
▪ Groundwater Sampling
(Procedures/analytes/
methods)
▪ Time-frame for field
activities
▪ Turn-around time for
analytical data
▪ Reports
VIII.Optimize the Design
Field work
The Geoprobe®
was used to
sample soil.
! A hand auger was
used to collect soil
samples in terrain
not accessible with
the Geoprobe®.
!
Field Work
Establishing a piezometer using the Geoprobe®.
Field work
Samples were
screened for VOCs,
PCBs and metals onsite using the mobile
lab.
Field Work
!
!
A geologist was on
site to examine and
log soil cores.
Soil samples
collected with the
Geoprobe® can be
screened on site or
sent to a fixed-based
lab for analysis.
Field Work
!
Samples were
screened for VOCs,
PCBs and metals onsite using the mobile
lab.
!
Confirmatory
samples were sent to
the State-contract
VAP certified lab.
Ecological Assessment
Ohio EPA Division of
Surface Water,
Ecological Assessment
Section staff returned to
the site in August to
assess biological and
water quality and to
conduct sediment
sampling in Stillwater
Creek adjacent to the
property.
Ecological Assessment
Ecological Assessment
Findings of the SIFU investigation
!
Lead and arsenic exceed residential DCSS in all
areas - compactor, junk shop, scrap yard,
vegetation north and vegetation south. (Lead
also exceeds commercial/industrial standard.)
!
TPH (DRO) in soil exceeds petroleum standards in
compactor area only.
!
VOCs, SVOCs, PCBs all present, but below
residential DCSS.
!
Lead in ground water exceeds generic standard
(to be verified through monitoring well
installation and sampling).
Tasks to be completed
!
Complete Phase II Property Assessment to
include ground water characterization,
ground water classification and (probably)
risk assessment.
!
Implement remedies that may include
O&M Plan, Risk Mitigation Plan, Property
Use Restrictions or cover materials.
!
Estimate remediation costs and apply for
Clean Ohio funding.
With all of the
efforts put into
this project,
the end result
is a true
"thumbs-up"
experience.
