BoRit Superfund Site TimelineBoRit Superfund Site Timeline

•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.

•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.

•A list of the most serious sites identified for possible long-term cleanup.

•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.

•If the release of hazardous

substances requires immediate or short-

term response actions, these are

addressed under the Emergency Response

program of Superfund.

•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.

•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.

•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.

•Work began November 2009.

•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.

• Activity based sampling occurred in summer/fall 2011.

•Proposed to the NPL September

2008.

•In April 2009, the site was listed on the NPL, making

the site eligible for federal cleanup

funding.

•EPA expects to complete the

RI/FS in approximately 3 years, depending on the needs of

the investigation.

Please Note: Time frames for site activities can vary depending on influences such as schedules, contracts and weather. Draft updated March 12, 2012

•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

•Preparation and

implementation of plans and

specifications for applying

site remedies.

•All new fund-financed

remedies are reviewed by the National

Priorities Panel.

•Ensures that Superfund

response actions provide for the

long-term protection of human health

and the environment.

•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.

•Removes a site from the NPL once all

response actions are

complete and all cleanup goals have

been achieved.

Notes

•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.

NotesNotes Notes

•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.

Please Note: Time frames for site activities can vary depending on influences such as schedules, contracts and weather. Draft updated March 12, 2012

•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.
