EPA Selects Cleanup Plan
The U.S. EPA, with concurrence from the
Pennsylvania Department of Environmental
Protection, has selected the cleanup plan to address
contaminated waste and soils associated with the
Clearview Landfill portion of the Lower Darby
Creek Area Superfund Site, also know as Operable
Unit 1 (OU1). The selected cleanup plan for OU1 is
documented in the Record of Decision (ROD) and is
summarized on the next page.
In August 2013, EPA released the Proposed Plan for
public review and comment on the preferred cleanup
option. We received more than 130 comments from
the community and our responses to those comments
are documented in the ROD in the section titled Re-
sponsiveness Summary. To view a full copy of the
ROD, the Responsiveness Summary, and documents

Description of the Cleanup
Plan
EPA selected an Evapotranspiration (ET) cover as
the cleanup plan for (OU1). An ET cover, also called
a water balance cover, is a thick layer of soil with a
dense strand of trees and vegetation planted on its
surface. The soil and tree cover absorbs precipitation
and holds it until the water can evaporate or be used
by the trees and vegetation. The roots of the trees
and vegetation also prevent erosion of the landfill
cover.
Now that the ROD is signed EPA will work with the
Potentially Responsible Parties (PRPs) to design the
cleanup plan. This process typically takes 12-36
months to complete.
In addition to the ET Cover, the other main parts of
the plan are:
~ Excavating contaminated soils outside the ET
cover itself that are above cleanup levels.
~ Long-term erosion controls along creek banks.
~ Permanent relocation of businesses from the land-
fill.
~ Collecting and treating the leachate using a sub-
surface trench along the creeks and engineered
wetlands.
~ Long-term maintenance and monitoring for all
parts of the remedy.
~ Legal controls to protect the remedy and public.

Benefits of the ET Cover
ET covers have been successfully installed at a vari-
ety of sites across the country. The ET cover for
Clearview Landfill will:
~ Provide long-term protection to the community
and the environment by preventing exposure to
contaminants above cleanup levels.
~ Compared to the other cleanup options that were
considered, the ET cover :
- Is just as effective,
- Can be constructed in less time,
- Is more cost-effective,
- Is durable and requires less long-term
maintenance; and,
- Provides greater environmental benefits.
Groundwater Investigation Update
~ EPA is also conducting a separate groundwater
investigation for the Clearview Landfill. A plume
of the contaminant 1,4-dioxane has been detected
in the overburden groundwater and extends sev-
eral hundred feet east of the landfill. A smaller
area of groundwater contaminated with 1,4-
dioxane and trichloroethene (TCE) was found in
the bedrock groundwater and is moving south of
the landfill.
~ The contaminated groundwater is not being used
by anyone for drinking or other uses. There is no
evidence that anyone is being exposed to the con-
taminants in the groundwater at this time.
~ An additional groundwater investigation is also
being conducted at the Folcroft Landfill, by a
group of responsible parties, which has also been
contaminated by 1,4-dioxane and TCE. As with
Clearview, this groundwater is not being used for
any purposes and there is no evidence that people
are being exposed to the groundwater.

EPA s Commitment to Community
Involvement
Technical Assistance Programs
The goal of Superfund community
involvement is to advocate and
strengthen early and meaningful
community participation during
Superfund cleanups.
In May 2014, an independent Community Assess-
ment was completed with the purpose to identify key
community issues and concerns and develop recom-
mendations for improved communications. In con-
junction with the results of the assessment, EPA is:
~ Taking action on many of the community assess-
ment recommendations and meeting with repre-
sentatives from the community organizations and
increasing the number and frequency of our meet-
ings with residents most affected by the cleanup
activities.
~ Seeking ongoing input from the community and
providing updates about our work as we make
progress.
~ Offering technical assistance resources to the
community in an effort to enhance two-way com-
munication.
~ Working with various government health organi-
zations and the University of Pennsylvania to
evaluate various health concerns expressed by the
community.
~ Updating the Community Involvement Plan (CIP)
for the entire LDCA Site. The CIP will document
how EPA will keep the community informed
throughout the cleanup process and will include
recommendations from the May 2014 Community
Assessment.
Technical Assistance Grant (TAG): Provides
money for activities that help your community partic-
ipate in decision making at eligible Superfund sites.
A TAG has been awarded to the Darby Creek Valley
Association. For more information, go to:
http://www.dcva. org
Technical Assistance Services for Communities
(TASC): Provides experts who can explain haz-
ardous waste problems in the community and EPA's
cleanup plan and other technical information.
Community Advisory Group (CAG): Provides a
public forum for community members to present and
discuss their needs and concerns related to the Super-
fund decision-making process.
Superfund Job Training Initiative (SuperJTI):
Supports job training programs in communities af-
fected by nearby Superfund sites and encourages the
employment of trainees at local site cleanups.
