Today, the White House issued a memo to the heads of federal agencies regarding risk assessments — a process by which agencies identify and evaluate risks such as toxic exposure or structural failure. Susan Dudley, head of OMB's Office of Information and Regulatory Affairs, and Sharon Hays, a senior official in the Office of Science and Technology Policy, issued the memo. The memo takes existing principles from a 1995 White House memo and includes additional text in order to place the Bush White House spin on each item.
