Reuse and the Benefit to Community
Waste Disposal, Inc. Superfund Site
Executive Summary
The Waste Disposal, Inc. (WDI) Superfund site is a former waste disposal area in southern California.
Collaboration and cooperation between EPA, the City of Santa Fe Springs, the California Department of Toxic
Substances Control (DTSC), the Regional Water Quality Control Board (RWQCB), multiple responsible parties and
business owners has led to its successful cleanup and continued use. Stakeholders recognized the need for
businesses to be able to remain open during and after cleanup. Maintaining future commercial and industrial
development opportunities was also important for the area's economy. EPA worked with the community to
ensure the compatibility of the remedy with existing land uses. Today, diverse commercial and light industrial
facilities are open for business. Existing buildings host manufacturing facilities, an equipment rental company,
vehicle maintenance facilities, construction firms and a sound recording studio. This case study explores the
site's cleanup and reuse, illustrating the opportunities and positive impacts of Superfund redevelopment in
action.
Positive Impacts
•	Site businesses employ over 160 people, providing annual employment income of about $9.5
million to the local community.
•	Over 40 commercial and light industrial businesses are currently active at the site.
•	In 2013, site properties generated over $144,000 in tax revenues and have an estimated
property value of $9.7 million.
•	EPA's cleanup plan allowed for the ongoing use of site buildings, enabling businesses to remain
open throughout the cleanup process.
•	In 2013, site business sales reached nearly $23 million.

Introduction
Superfurid cleanups restore value to properties and benefit surrounding communities. Once a property is ready
for reuse, it can strengthen a local economy by supporting jobs, new businesses, tax revenues and spending.
Cleanups may also take place while properties are in active use. This case study captures the on-site and
community impacts of well-coordinated cleanup and continued use at the WDI Superfund site.
The 38-acre WDI Superfund site is located in Santa Fe Springs, a city in southeastern Los Angeles County,
California (Figure 1). Light industrial facilities, commercial areas and neighborhoods surround the site. Santa Fe
Springs Road borders the site to the northwest. Los Nietos Road is located to the southwest (Figure 2). Greenleaf
Avenue is located to the southeast. A warehouse and a private high school are located northeast of the site.
According to 2012 Census data, about 16,700 people live in Santa Fe Springs.
Site History
The center of the WDI site contains a 42-
million-gallon, concrete-lined reservoir. The
reservoir, also known as the dial, was used
for crude petroleum storage in the 1920s
and 1930s. Between the early 1940s and
the mid-1960s, the dial was used for
disposal of a variety of hazardous
substances, including liquid and solid
wastes. These wastes included petroleum-
related chemicals, solvents, sludge,
construction debris, drilling muds and other
materials. Wastes were also disposed of in
areas surrounding the reservoir.
Disposal activities were unregulated until
1949; Los Angeles County permitted
disposal activities from 1949 until the dial's
closure in 1964. While disposal activities
continued during the 1950s, the reservoir
and areas nearby were gradually developed
for commercial and industrial uses, In 1984
and 1985, testing by the City of Santa Fe
Springs detected hazardous substances in
site soils. Based on these findings, EPA
placed the site on the Superfund program's National Priorities List (NPL) in July 1987.

In 1988 and 1989, EPA did a remedial investigation and feasibility study to determine the nature and extent of
contamination at the site and to identify long-term cleanup options. EPA identified the reservoir in the dial's
central area and waste materials in surrounding areas as the primary sources of contamination. Contaminants of
concern included volatile organic compounds (VOCs), metals, pesticides, polychlorinated biphenyls (PCBs) and
polycyclic aromatic hydrocarbons (PAHs).

Property Cleanup and Transformation
Early on, EPA fenced the site to secure the area and prevent potential
human contact with site contaminants. EPA also put in multilingual
signs to inform the public of potential health risks. EPA selected a
cleanup plan to address site contamination in 1993 and updated it in
2002. It addressed waste materials, contaminated soil, subsurface
liquids, subsurface gases and ground water conditions. Cleanup
activities included covering the site with a protective cap, collecting
and treating soil gases, collecting and removing site liquids,
controlling stormwater drainage, long-term ground water and soil
vapor monitoring, and water use restrictions. The selected remedy
also included soil gas and indoor air monitoring, engineering controls
and institutional controls.
Figure 3: Cleanup of the dial area.
EPA, property owners, the City of Santa Fe Springs and the parties responsible for generating the site waste -
known as the Waste Disposal, Inc. Group, or WDIG - worked together so that the site's cleanup would protect
public health and the environment, while also making it possible for businesses on site to remain open. A key
early challenge was how to manage contaminated soils located beneath the many buildings on site. Removing
the soils was impractical; it would have required extensive demolition of active facilities. WDIG worked with EPA
and site property owners on parcel-specific cleanup plans for each structure. WDIG inspected existing buildings,
sealed building foundations and repaired cracks in floor slabs to prevent vapor intrusion from the soil below.
WDIG also repaved business driveways, parking areas and walkways, extending the site's capped area to cover
wastes buried around and between businesses. In addition, WDIG worked with the nearby high school to
address public safety concerns. WDIG built a large backstop behind the school's baseball and soccer fields to
prevent stray balls from entering the site, eliminating the need for students to enter the site to retrieve them.


The City of Santa Fe Springs also played an important role in the site's
cleanup and continued use. In 2000, EPA awarded the locality a
$100,000 Superfund Redevelopment Initiative (SRI) grant to support
a community-based planning project supporting future use. Based on
the project's findings, the city designated the site for industrial uses
and developed the site's Specific Use Plan, which provides guidelines
for future site development. Parts of the site - the central dial area
and sections along Greenleaf Road - are vacant and available for
development. EPA and WDIG coordinated with the City to ensure the
site's cleanup and land use plans were consistent with EPA's selected
cleanup strategy. The City's plan requires engineering controls, such
as vapor barriers, for any buildings built on site in the future. The
plan also called for restrictive covenants requiring EPA approval prior
to new construction. The covenants, now in place, ensure the integrity of the remedy and minimize the potential
for exposures to hazardous substances. Santa Fe Springs' City Council officially adopted the plan in May 2004.

EPA worked closely with the City, property owners and the broader community throughout the cleanup to share
information and bring reuse ideas into the Superfund process. In 2003 and 2004, for example, EPA and WDIG
hosted several informal open house meetings. EPA and WDIG representatives met with the community in small
groups to discuss the project and potential impacts on area businesses. In one case, EPA staff hosted a large
outdoor loading dock meeting at an adjacent business to update employees about the ongoing cleanup. EPA
also worked closely with the community and business representatives to minimize inconveniences caused by the

cleanup. EPA, DTSC and other public entities also formed an Interagency Committee (IAC). The U.S. Army Corp of
Engineers (USAGE) helped review design documents and inspect construction work. The IAC coordinated
technical reviews, worked with PRPs, and hosted public meetings to provide the community with regular
updates. The RWQCB also provided guidance and oversight for water-related aspects of the Site's cleanup. EPA
approved on the site's remedial action completion report in September 2006, marking the completion of the
site's cleanup. PRPs continue to perform long-term operations, maintenance and environmental monitoring
under EPA oversight.
Local Impacts
The site's successful cleanup protects public health and the environment, and has had a significant positive
impact on the local economy. Originally, EPA envisioned that some business relocations might be necessary due
to the location of waste under existing buildings. However, careful planning and cooperation between EPA and
the IAC allowed the continued operation of Site businesses, preventing the costs and disruptions associated with
business relocations. By remaining open during and after cleanup, businesses have continued to support jobs
that generate revenues, income and spending in the area. Today, the site is home to 44 companies. They
provide about $10.1 million in employment income and generate local and state sales and property tax
revenues. Following are highlights of some of the site businesses.

collection of sales taxes, which support state and local governments.1
Future Site Use
The central dial area and parcels of land along Greenleaf Avenue
are undeveloped. These areas are among the last large open
spaces available in Santa Fe Springs, making them sought-after real
estate. The City and local developers are currently exploring
potential projects that would be compatible with the site's
remedy.

Conclusion
Collaboration and cooperation among EPA, local and state
agencies, WDIG, site business owners and the community was vital
to the successful cleanup and continued use of the WDI Superfund
site. EPA's carefully designed cleanup, which relied on existing
infrastructure to help prevent exposure to site contaminants, not
only protected public health and the environment, but also enabled businesses on site to remain open. Today,
site uses support local economic growth, providing over 160 jobs and about $9.5 million in annual employee
income. These businesses also generate sizable tax revenues and provide the community with a wide variety of
commercial and industrial services. Looking to the future, the site's cleanup has also set the stage for additional
redevelopment opportunities in an area where vacant property is in high demand.
