1 BoRit Superfund Site Timeline Removal Action Preliminary Assessment/Site Inspection National Priorities Listing (NPL) Process Remedial Investigation (RI) Feasibility Study (FS) 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 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. 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 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 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.

EPA expects to complete the RI/FS in approximately 3 years, depending on the needs of the investigation.

The bulk of the cleanup usually occurs during this phase.

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. 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.
