OMB Watch has assembled this list of midnight regulations finalized during the Bush administration. If you know of additional regulations, or have additional information on efforts to undo any of these actions, please leave your thoughts in the comment section below. (Last updated Dec. 6, 2010.)

Effective Feb. 10, the Consumer Product Safety Commission (CPSC) will begin enforcing new standards for children's products containing lead and phthalates. The standards take effect just days after a federal court voided a Bush administration effort to legalize the sale of products not meeting the standards if the products had been manufactured before Feb. 10. CPSC is enforcing the regulations in response to a 2008 law that gives the agency new powers and responsibilities to protect the public from potentially dangerous consumer products.

The Bush administration rushed out a host of problematic regulations in its final months. Many of these "midnight" regulations actually represent deregulatory actions that weaken or eliminate safeguards protecting health, safety, the environment, and the public's general welfare. Now, the Obama administration and Congress bear the responsibility for undoing Bush's last minute actions. Check here frequently for the latest news. 

Just hours after President Barack Obama took the oath of office on Jan. 20, new White House Chief of Staff Rahm Emanuel issued a memo setting out the Obama administration's policy for dealing with some regulations left by the administration of President George W. Bush. The Emanuel memo puts a freeze on all regulations still in the pipeline and gives agencies leeway to deal with those Bush-era regulations already finalized but not yet being implemented. However, the memo does not address most of the controversial regulations finalized by the Bush administration in its last days; these rules are already in effect and impacting the nation.
