WHTI became law in December of 2004. It became known in April of 2005, when they started releasing the rollout of the law. A final rulemaking has come out. We've submitted to the first rulemaking--there was an opportunity to submit input--and we've submitted now to the final rulemaking.
It will take effect on January 8 of 2007 for air and sea and on January 1 of 2008 for land.
