This is one of a series of guidance manuals that provides information on standards for facilities that treat, store, or dispose of hazardous waste. The manuals are being developed to assist permit writers in evaluating facilities against standards (40 Code of Federal Regulations, Part 264) issued by the U.S. EPA under Subtitle C of the Resource Conservation and Recovery Act of 1976, as amended. Included in these documents is detailed information about design, equipment, and specific procedures for evaluating data submitted by the permit applicant. The guidance manuals also contain bibliographies that can be used to locate additional information.
