Under United States environmental policy, hazardous waste is a waste (usually a solid waste) that has the potential to: *cause, or significantly contribute to an increase in mortality or an increase in serious irreversible, or incapacitating reversible illness; or *pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, or disposed of, or otherwise managed. Many types of businesses in the United States generate hazardous waste. Some are small businesses that may be located in a community. For example, dry cleaners, automobile repair shops, hospitals, exterminators, and photo processing centers all generate hazardous waste. Some hazardous waste generators are larger companies like chemical manufacturers, electroplating companies, and oil refineries. In the United States, hazardous wastes generated by commercial or industrial activities may be classified as "listed" hazardous wastes or "characteristic" hazardous wastes by the United States Environmental Protection Agency (EPA). Under the 1976 Resource Conservation and Recovery Act, a facility that treats, stores or disposes of hazardous waste must obtain a permit for doing so. Generators of and transporters of hazardous waste must meet specific requirements for handling, managing, and tracking waste. Through the RCRA, Congress directed the EPA to create regulations to manage hazardous waste. Under this mandate, the EPA developed strict requirements for all aspects of hazardous waste management including the treatment, storage, and disposal of hazardous waste. In addition to these federal requirements, states may develop more stringent requirements or requirements that are broader in scope than the federal regulations. EPA authorizes states to implement the RCRA hazardous waste program in lieu of the federal program. For states to receive authorization, they must maintain standards that are equivalent to and at least as stringent as the federal program. Implementation of the authorized program usually includes activities such as permitting, corrective action, inspections, monitoring and enforcement. ==Regulatory history== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hazardous waste in the United States」の詳細全文を読む スポンサード リンク
