Brownfield land
Brownfield is a term used in urban planning to describe land previously used for industrial purposes or some commercial uses. Such land may have been contaminated with hazardous waste or pollution or is feared to be so. Once cleaned up, such an area can become host to a business development such as a retail park. Land that is more severely contaminated and has high concentrations of hazardous waste or pollution, such as a Superfund site, does not fall under the brownfield classification. ''Mothballed brownfields'' are properties that the owners are not willing to transfer or put to productive reuse.
The term applies more generally to previously used land or to sections of industrial or commercial facilities that are to be upgraded, although this usage is becoming more commonplace.
== United States ==
The term ''brownfields'' first came into use on June 28, 1992, at a U.S. congressional field hearing hosted by the Northeast Midwest Congressional Coalition. Also in 1992, the first detailed policy analysis of the issue was convened by the Cuyahoga County Planning Commission. The United States Environmental Protection Agency selected Cuyahoga County as its first brownfield pilot project in September 1993.
