Two articles from the Martindale.com website explore the Final Rule issued on November 1, 2005 by the EPA. The rule doesn’t differ much from the earlier proposed rule and clarifies what the agency considers to satisfy the "all appropriate inquiries" standard under CERCLA. As the first article by Suzanne C. Lacampagne and Hong N. Huynh comments, "The long-awaited rule provides some clarification with respect to the responsibilities of potential buyers of environmentally contaminated property as well as imposes additional burden on them." The second article by Jean H. McCreary and James S. Kerouac presents some of the same information with a slightly more purchaser-oriented analysis. Registration is free but required for full access to both articles. The text of the final rule can be found here in PDF format.
