BoRit Superfund Site Timeline
•A “removal action” is an
action intended to stabilize or
clean up an incident or site
which poses an immediate
threat to human health or the
environment.
•A Preliminary Assessment
(PA) is designed to determine
whether a sites poses little or
no threat to human health and
the environment or if it does
pose a threat, whether the
threat requires further
investigation.
•If the release of hazardous
substances requires immediate
or short-term response
actions, these are addressed
under the Emergency
Response program of
Superfund.
•A Site Inspection (SI)
identifies sites that enter the
NPL listing process and
provides the data needed for
Hazard Ranking System
(HRS) Scoring and
documentation.
BoRit Process
•Phase I: July 2008-June 2009 –
Stabilization of stream banks so
that asbestos-containing material
(ACM) does not enter the streams is
begun. In June 2009, EPA
completed stream bank
stabilization at Wissahickon Creek.
•Phase II: July 2009-May 2010 Stream bank stabilization was
completed at Rose Valley Creek.
•Phase III: May 2010-June 2010 –
Stabilization completed on the
reservoir berm parallel to the
Wissahickon Creek.
•Phase IV: June 2010-July 2011 - Pile
clearing and stabilization of
Tannery Run completed.
•Phase V: July 2011-September 2011
– Stabilization completed at
Wissahickon Creek from the dam to
its confluence with Tannery Run.
•A list of the most
serious sites identified
for possible long-term
cleanup.
•After a site is listed on the
NPL, a Remedial
Investigation/Feasibility
Study (RI/FS) is performed
at the site.
•The RI serves as the
mechanism for collecting
data to:
characterize site
conditions;
determine the nature of
the waste; and
assess risk to human
health and the environment.
•The Feasibility Study
(FS) is the mechanism for
the development,
screening, and detailed
evaluation of alternative
remedial actions.
•The RI/FS is a multi-step
process including:
Scoping
Site Characterization
Development and
Screening of Alternatives
•Work began November
2009.
•In April 2006, an EPA
Site Assessment Team
conducted a baseline
sampling event at the
BoRit Asbestos Site.
•Results from the
sampling event showed
the presence of asbestos
in the air, soil, surface
water and sediments.
•Proposed to the NPL
September 2008.
•In April 2009, the site
was listed on the NPL,
making the site eligible for
federal cleanup funding.
Please Note: Time frames for site activities can vary depending on influences such as schedules, contracts and weather.
•Phase I of field work, which
included surface water,
sediment, soil, and waste
sampling, completed January
2010.
•Phase II activities, which
included community air
monitoring, installation of
groundwater monitoring wells,
and additional onsite and offsite
(including residential) soil
sampling, began October 2010
and completed November
2010.
•EPA expects to
complete the RI/FS in
approximately 3 years,
depending on the needs
of the investigation.
• Activity based sampling
occurred in summer/fall 2011.

BoRit Superfund Site Timeline
•A ROD contains site
history, site
description, site
characteristics,
community
participation,
enforcement
activities, past and
present activities,
contaminated media,
the contaminants
present, scope and
role of response
action and the
remedy selected for
cleanup.
•Preparation and
implementation of
plans and
specifications for
applying site
remedies.
•All new fundfinanced remedies are
reviewed by the
National Priorities
Panel.
•Remedial Action
(RA) follows the
remedial design
phase and involves
the actual
construction or
implementation
phase of
Superfund site
cleanup.
•The bulk of the
cleanup usually
occurs during this
phase.
•Ensures that Superfund
response actions provide
for the long-term
protection of human
health and the
environment.
•Included here are:
Long-Term Response
Actions
 Operation and
Maintenance
Institutional Controls
 Five-Year Reviews
 Remedy
Optimization
•Removes a site
from the NPL once
all response actions
are complete and
all cleanup goals
have been achieved.
•EPA’s goal is to make
sure that at every cleanup
site, the Agency and its
partners have an effective
process and the necessary
tools and information
needed to fully explore
future uses, before the
cleanup remedy is
implemented.
•This gives the Agency the
best chance of making it’s
remedies consistent with
the likely future use of the
site. In turn, EPA gives
communities the best
opportunity to use sites
following cleanup.
BoRit Process
•It is important to note
that EPA has NOT
chosen a long-term
cleanup option for the
site.
•EPA plans to work
with the community to
keep them informed of
our progress and of the
options we’re
considering for the final
cleanup.

•Once the RI/FS is
completed, EPA will
propose a final cleanup
option and will offer the
community a sixty day
period to comment on
the proposed plan.
Please Note: Time frames for site activities can vary depending on influences such as schedules, contracts and weather.
