Brownfields to Cleanfields


The term "brownfield site" means real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant.


U.S. Environmental Protection Agency

There are over 450,000 designated brownfield sites in the United States, all of them representing opportunities for redevelopment supported by a wide array of Federal and State incentives. The U.S. Environmental Protection Agency has specifically recognized the potential of converting brownfield sites to alternative fuelling stations, and in 2008 launched the Re-Powering America's Land initiative to encourage the development of renewable energy on potentially contaminated land. The EPA's Office of Underground Storage Tanks (OUST) is collaborating with the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) to promote the development of alternative fuel stations on these sites.

Unlike heavily contaminated Superfund or potential Superfund sites, brownfield sites typically involve relatively mild levels of environmental contamination. A common example would be a disused filling station with leaking underground tanks. These sites can be effectively remediated by well established engineering techniques. The combination of effective remediation with construction of alternative fueling stations replaces an environmental liability with an environmental asset, and the ability to tap incentives for both brownfield remediation and alternative energy development.

Cleanfield Energy, Inc. is a specialist in the conversion of brownfield sites to clean, profitable alternative fueling stations. Our staff can assist communities or filling station investors in developing the plans and documentation needed to secure the highest possible degree of official support, which can provide up to 100% of remediation and development cost and continuing business incentives. CEI's strategic partners have extensive experience in remediation engineering and alternative fueling station construction, allowing Cleanfield Energy, Inc. to present one-stop packages for the entire remediation, conversion, development, and operation process.

Thousands of gasoline stations have shut down over the past 50 years. Many of them could be regarded as petroleum brownfields because they have the presence, or potential presence, of contamination… At the same time, there is a large push to increase the amount of alternative fuels used in vehicles in the United States because of their numerous environmental, economic, and geopolitical advantages. All of these fuels require refueling facilities that are convenient to vehicles, which tend to be the same sites as former gasoline stations.
