OSHA dosent really write the standards, they take industry standards like the NFPA 70E, change the wording to make it enforcable, and publish it as an OSHA standard.
The upcoming release of the new OSHA electrical standard is based on the 2004 NFPA 70E. The person who was the chairman of the 70E commitee now works for OSHA, probally to help with the release of enforcement of the new proposed standard.
Big Ed, there is a video on the internet of David Wallace from OSHA discussing OSHA's viewpoint of enforcement and compliance of the 70E, you should be able to find this video with a quick google search.
