Environmental activists have long focused criticism on the amount of fuel consumed by cross-country and international jet travel, but government and academic researchers announce that they are researching alternative fuels for jets. A usable product is years away, but the length of time such an endeavor takes is only one of the many challenges facing development of these alternative fuels:

  • Such fuels are even more expensive than Jet A right now.
  • The fuels are difficult to transport and manage in harsh weather conditions, making snow-prone northern climes more costly for such fuel usage.
  • Some of the alterna-fuels, such as biodiesel, freeze at lower temperatures – making high altitudes "interesting" (tm Peter Kirsch)

Regardless, the inquiry is a positive development. TAL hopes the project proceeds apace and leads to a usable product soon.

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.
