The Commerce Department has prepared a list of 20 regulations that business people find most burdensome and costly.

The list, quickly dubbed "the Terrible 20" by the U.S. Chamber of Commerce, was culled from nominees that business sent to the Task Force on Regulatory Relief at the request of Vice President Bush.

Five agencies were responsible for most of the 20 -- the Environmental Protection Agency, the Nuclear Regulatory Commission and the Labor, Energy, and Health and Human Services departments. Many of the regulations have already been targeted by the administration's regulatory reformers and a new list of regulations to be reviewed is expected to be released shortly.

Here is the list of regulations, with business' estimated costs of industry-wide compliance, where available.
