Underground Storage Tanks (USTs)

Petroleum Brownfields


Brownfield is a term applied to a property where its expansion, redevelopment, or reuse may be complicated by the presence or potential presence of a hazardous substance. A petroleum brownfield is a type of brownfield where the contaminant is petroleum.

Of the estimated 450,000 brownfield sites in the U.S., approximately one-half are thought to be impacted by petroleum, much of it from leaking underground storage tanks (USTs) at old gas stations. These sites blight the surrounding neighborhoods and threaten human health and the environment. Petroleum can contaminate groundwater, the source of drinking water for nearly half of all Americans.

Petroleum brownfields, such as old abandoned gas stations, are being cleaned up and reused to the benefit of communities across the country. EPA’s Office of Underground Storage Tanks (OUST) and Brownfields Program jointly focus on the cleanup and reuse of petroleum-contaminated sites. The Brownfields Program awards brownfields grants for the assessment and cleanup of petroleum brownfields (e.g., those determined to be relatively low-risk priority).

OUST is responsible for promoting the cleanup of federally-regulated leaking underground storage tank sites (e.g., high risk petroleum release sites). Once a site is cleaned up, it can be reused and provide new businesses, jobs, and tax revenue or other amenities for the community, such as parks and recreation, increased property values, and improved walkability.

History of EPA Petroleum Brownfields

Since its inception in 1995, EPA's Brownfields Program has grown into a results-oriented program that has changed the way contaminated property is perceived, addressed, and managed. Initially, EPA provided small amounts of seed money to local governments that launched hundreds of two-year brownfield pilot projects.

Petroleum-contaminated sites were not eligible for traditional brownfields funding. Through passage of the Small Business Liability Relief and Brownfields Revitalization Act in 2002, brownfields policies that EPA developed over the years were passed into law. A key provision of the law allocates 25 percent of brownfields funding each year to assess, clean up, and ready for reuse relatively low-risk petroleum brownfield sites.

Identifying, Assessing, and Cleaning Up Petroleum Brownfields

It is not hard to locate petroleum brownfield sites. Sometimes it is as simple as driving past and taking note of an old abandoned gas station and then checking with your state implementing agency for information on the site. Many state and local government websites contain lists (often called inventories or databases) of brownfield properties, including petroleum sites, within their jurisdictions. EPA encourages states and local areas to develop and maintain lists or inventories of brownfield properties that could potentially be reused. Your state implementing agency or state brownfields program is the best place to find a listing of brownfield sites.

Once identified, the management of a petroleum brownfield site requires specific technical expertise. A petroleum-contaminated site must first be investigated (assessed) to determine the nature and extent of the contamination. An assessment will guide how a site is to be cleaned up. As much as possible, it is important to consider the reuse of a petroleum brownfield site when planning to clean it up. In several states the potential reuse of a site can affect the cleanup design. Petroleum-contaminated sites that are to be cleaned up and reused for residential housing, for example, may require more stringent remediation than for a parking lot where contamination may be encapsulated and paved over.

Identifying Petroleum Brownfields

Petroleum contamination can be found at many different types of properties. Many abandoned sites, such as old gas stations, auto service businesses, factories, mill sites, shipyards, transit stations, and junkyards have been found to be contaminated by petroleum. A property that is perceived to be contaminated by petroleum is a potential petroleum brownfield site until assessment of the site proves there is no petroleum contamination or clearly identifies contaminants of concern so they can be cleaned up to meet the designated end use.

The size of petroleum brownfield varies significantly; some sites are smaller than an acre, while other sites are huge former industrial properties. Some sites are bare soil, while others have existing buildings and infrastructure. For redevelopment purposes, it is important to remember that small sites can be combined to make larger sites if that is what is needed.

State and Local Inventories of Petroleum Brownfield Sites

Below are just a few examples of the lists (often called inventories or databases) of brownfield sites compiled by some states and local jurisdictions. State and local officials use these inventories to promote the availability and marketability of their petroleum brownfield sites. Developers and others use the lists to look for potential reuse sites. Some inventories contain only addresses of petroleum sites while others contain detailed information or maps of brownfields sites. Even if an area does not have a brownfields inventory, they may have publicly available information about leaking underground storage tank sites, some of which could be petroleum brownfields.

Assessing and Cleaning Up Petroleum Brownfield Sites

The petroleum assessment and cleanup process varies by state. Each contaminated site must be cleaned up to satisfy state and federal requirements. State requirements usually match and often surpass the federal requirements. For petroleum brownfield site assessments and cleanups, implementing agencies are often the first place to seek information and assistance, and states maintain websites with this information.

Addressing Liability Issues

EPA encourages the cleanup and revitalization of contaminated properties by clarifying Superfund liability concerns and implementing the landowner liability protections. However, petroleum brownfields do not always fall under those protections. If someone buys a property with petroleum contamination, they could become legally responsible for cleaning up that contamination. Prospective purchasers should start coordinating with relevant regulatory authorities as early as possible to protect themselves from liability during and after the cleanup and reuse of the property.

Financial Resources

There are numerous sources of financial assistance for the cleanup and redevelopment of petroleum-contaminated sites. Many local, state, and federal government environmental and economic development programs provide financial assistance in the form of grants and cleanup funds. The resources highlighted in this section provide a brief glimpse into common revitalization themes.

Beyond this assistance is a wealth of public and private resources that may be available depending on the intended reuse of a cleaned up site. For instance, parks and recreation programs at the local, state, and federal government levels may have resources devoted to the development of new parkland or recreational facilities. Federal, state, and local housing authorities may have resources devoted to developing low-income housing. Many governments also provide tax incentives to encourage redevelopment.

Federal Government Programs

Each year, EPA awards brownfields grants to local governments, states, tribes, and non-profit organizations to assess and clean up brownfields, including those impacted by petroleum contamination. The Small Business Liability Relief and Brownfields Revitalization Act in 2002 outlines specific criteria by which petroleum sites may be eligible for brownfields grant funding. These criteria are briefly described as follows: the site must be of relatively low risk; there can be no viable responsible party; the applicant cannot be potentially liable for cleaning up the site; and the site must not be subject to a RCRA corrective action order.

To determine if a leaking underground storage tank site is eligible for brownfield grants, it may be necessary to request a determination of eligibility from the state petroleum regulatory authority regarding low-risk priority petroleum-contaminated or suspected sites. Where the state is unable to make the eligibility determination, EPA will make the determination. EPA will make the determination for tribes.

Aside from EPA funding, other federal programs administer resources for which petroleum brownfields are often eligible. The resources listed below describe of many of the other federal programs.

State and Local Programs

Many states also have programs and resources that provide technical and financial assistance for the assessment, cleanup, and reuse of petroleum sites. A good place to look for information are the state implementing agencies websites. Several of the guides below include information on both public and private funding.

Private Sector Resources

In the private sector, civic-minded organizations and trusts may have resources such as grants and loans to encourage the redevelopment of old sites. For example, a Habitat for Humanity project (PDF) (1 pg, 103 K, About PDF) worked with property owners and local governments to organize labor and other resources to reuse petroleum sites for affordable housing. Financial institutions may provide loans or other assistance for projects. Private sector resources include:

Reusing Cleaned Up Petroleum Sites

Petroleum brownfield sites are being cleaned up and reused for many different purposes across the U.S. Some old abandoned gas station sites are now the locations for new businesses and new affordable housing. This section provides numerous examples of how petroleum brownfields are being reused and offers ideas to consider when planning a petroleum brownfields reuse.

The cleanup and reuse of a petroleum site is a contribution to sustainable environmental practice. Cleaning up and reusing petroleum-contaminated land saves pristine land elsewhere from development and potentially from future contamination. As much as possible, it is important to consider the reuse of a petroleum brownfield site when planning to clean it up. It takes close cooperation among many differing parties to plan and carry out a petroleum brownfields reuse project. Federal, state, and local governments are often involved in the cleanup and reuse of petroleum brownfields, as are the assistance and resources of private entities.

Successful government involvement in a revitalization project usually involves collaboration across program lines and between different governments. It is important that all levels of government - federal, state, and local - work together. Within each government level, tank remediation, brownfields, revitalization, and economic development programs must cooperate to fully capitalize on the potential of reusing petroleum brownfield sites. Depending upon the reuse of a site, it is possible that government offices including housing, parks and recreation, and others may become involved.

For a description of how Colorado used cross-program cooperation for brownfields, see "Colorado's Historic Byways Revitalization Initiative," Exit on page 5 of the September 2006 issue of LUSTLine, a publication of the New England Interstate Water Pollution Control Commission. EPA is committed to building partnerships to foster brownfields cleanups and reuse with all levels of government.

Public and Private Partnerships

There are many benefits from public and private partnerships for communities, and for regulators. These partnerships can promote the coordination of regulatory programs, the streamlining of administrative procedures, and a multi-stakeholder examination of cleanup solutions and risk sharing. In addition, public and private partnerships may pursue more public interest development and realize end-use possibilities for abandoned gas station sites that have societal benefits, such as a police station or a medical clinic. EPA is committed to building partnerships to foster brownfields cleanups and reuse.

Opportunities for Small Businesses

An old, abandoned property contaminated by petroleum can be an excellent site for a new small business. Abandoned gas station sites often have traits that can make them excellent locations for a small business, including:

  • Relatively small size that easily accommodates a small business
  • Prominent location, many times on a corner lot on busy thoroughfares
  • Already possesses necessary infrastructure, negating the need for expensive land clearing and for new access to water and power sources and other amenities
  • Useable buildings are already in place

In addition, many state and local areas have created incentives to foster the cleanup and reuse of these sites, including tax advantages or financial incentives.

Reuse Project Examples

This section provides success stories for petroleum brownfields categorized according to how a site is reused, such as for housing, commercial and business, public, or environmental and recreational reuse. Each success story includes a wealth of information on how the project was conducted, which can help others undertake and complete similar projects.

  • Housing Reuse: Petroleum-contaminated property has been cleaned up and reused for affordable housing, assisted living, public housing, and private residences.
  • Commercial And Business Reuse: Petroleum-contaminated properties are being cleaned up and reused for all sorts of businesses large and small. Small businesses find old gas station sites a perfect fit for a new fast food restaurant, bank, or pharmacy. Larger developments have occurred on larger properties or where smaller properties have been combined.
  • Public Reuse: Because old, abandoned gas stations are found in many communities, governments often find these sites to be excellent locations for new public services, such as firehouses, police stations, health care centers, education centers, and government services offices.
  • Environmental And Recreational Reuse: Petroleum-contaminated properties are being cleaned up and reused in ways that both enhance the environment and enrich community living. A cleaned up petroleum site can make a major contribution to cleaner water in rivers, lakes, and harbors and provide recreational facilities for the local community.
