The Environmental Protection Agency (EPA or "the Agency") is correcting errors and removing obsolete or redundant language in regulations regarding notification requirements for releases of hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Consistent with ongoing regulatory reinvention initiatives within the Agency, EPA has reviewed the CERCLA release reporting regulations and has identified several categories of errors, including: typographical errors in the table of CERCLA hazardous substances; definitions made legally obsolete because of changes in CERCLA's statutory provisions; and redundant or unnecessary information.
