Its central finding is that the combined value of the benefits of the 106 regulations far exceeded their combined cost: $136 billion to $651 billion in annual benefits versus $44 billion to $62 billion in annual costs (all figures are in 2001 dollars; the costs amount to much less than 1% of the economy).SHA estimated the cost of compliance to its new cotton dust standard as $280 million a year (1982 dollars). Actual costs turned out to be an estimated $83 million a year, or less than one third the expected amount. Costs were brought down as the byproduct of a movement toward plant modernization.
