EPA is correcting errors in the hazardous waste regulations that appeared in the Federal Register on December 6, 1990 (55 FR 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 (40 CFR 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. This notice corrects errors and clarifies language in the preamble and regulations of the December 6, 1990 final rule.
