In this rule, EPA corrected errors in the hazardous waste regulations that appeared in the Federal Register (FR) on December 6, 1990 (volume 55 of the FR starting on page 50450). In that rule, EPA promulgated regulations under the Resource Conservation and Recovery Act (RCRA) to add three categories of wastes to the list of hazardous wastes from non-specific sources (Title 40 of the Code of Federal Regulations in section 261.31). These wastes, designated F032, F034, and F035, are generated from wood preserving processes that use or have previously used chlorophenolic formulations, facilities that use creosote formulations, and facilities that use inorganic preservatives containing arsenic or chromium, respectively. EPA also promulgated standards for permitting an interim status for drip pads used to assist in the collection of treated wood drippage.
