Container and waste pile standards for owners and operators of hazardous waste facilities: consolidated permit regulations--Environmental Protection Agency. Amendments to interim final rule.

The Environmental Protection Agency (EPA) is today promulgating amendments to the hazardous waste management regulations regarding the management of hazardous waste in containers and piles and associated permit regulations (40 CFR Part 264, Subparts I and L, and Part 122, Subpart B). These amendments better tailor the standards to the particular type of hazard posed by specific situations. The standards for containers are amended to waive the containment system requirements for wastes that do not contain free liquids, provided that the wastes are protected from contact with accumulated liquid. The standards for waste piles are amended to waive the containment system requirements for wastes that do not contain free liquids, provided that the pile is protected from precipitation by a structure and from surface water run-on and wind dispersal of the waste by the structure or some other means. The Agency believes these amendments believes these amendments will not reduce the level of protection of human health and the environment.
